Future e-access to the primary literature

Editor-in-Chief, Nature
The topic of this Nature forum — the impact of the Web on the publishing of the results of original research — has, since the emergence of the Internet, filled volumes in the reports of conference proceedings and reams of individual articles. Many of the often arcane and complex socio-economic and technical issues involved are well-trodden paths for a narrow circle of specialists, and excellent in-depth coverage of the issue is regularly provided by specialists outlets such as the D-Lib Forum and the Journal of Electronic Publishing. The main aim of this forum is to bring some of the substance of this Brownian motion of Internet issues to a broader grassroots audience and debate the implications for the future dissemination of scientific information.

Beyond the academic debate, there is constant cross-fertilization. Science feeds the development of online initiatives with bold projects like Internet2 and computer 'Grids' and the commercial Internet provides new challenges and opportunities for scientists with the professionalization of technologies such as peer-to-peer computing. Then there is the plethora of joint initiatives in Extensible Mark-up Language (XML) and other standards and technologies. The list of potential Internet opportunities for science is endless.

The issue is, to say the least, multifactorial. At one level, there is the economics. It is hardly a state secret that some commercial publishers have charged high prices for low-circulation journals, and enjoyed very high profit margins while contributing to the so-called serials crisis. Few if any libraries can afford subscriptions to even a significant fraction of the literature (see Nature 397, 195-200; 1999).

The most recent and prominent manifestation of the debates surrounding this topic is an initiative by researchers — The Public Library of Science. (PLS) who, by threatening a boycott, are trying to force publishers to release archive reports of original research into centralized, (as opposed to dispersed) databases that are freely available and to which there is unrestricted access.

Is this the optimal solution?
The question is an open one. While this is a solution that has superficial appeal and is noble in its aspirations it does, on closer examination, raise many questions. PLS argues that its scheme poses few financial risks for publishers, but this is far from established. What about "responsible publishers" such as the non-profit learned societies, the revenues of whose journals often fund their core activities? Ann Okerson, Associate University Librarian at Yale University, warns that we must be careful not to thoughtlessly abolish a journal system which, for all its failings, works and replace it with a model that, while attractive, is still lacking in terms of detailed economics and how it would provide the quality controls that exist in the established system. The PMC option is also, in practice, dominated by the United States and this in itself raises serious issues.

That these topics are now being addressed in earnest is good news, but anyone who believes that they have a monopoly on the solution should be mistrusted; the socio-economic and other implications of the Web in science do not lend themselves to dogmatic solutions. While pressure for change can only be welcomed, the reality is that all of us involved in scientific information and exchange are in a phase of experimentation, the outcome of which remains uncertain. The challenge is to preserve the best of the current journals system, while seizing the opportunities of alternatives.

If we just look at the economics of scientific publishing, the landscape has completely changed over the past few years. The way in which electronic journals are bundled and sold (as opposed to the way print is distributed), means that powerful consortia of libraries and indeed whole countries can now use their collective weight to negotiate stiff deals with publishers and, in a market economy, this is a healthy development. Could it be that spreading the reduced but inevitable costs of quality electronic publication over a wider market might ultimately be a better solution than free access? This is also perhaps an open question.

The PLS initiative has drawn attention to the reasons for rethinking the traditional model and also promotes the idea of centralized databases. In stark contrast, most of those involved in the Internet business see a future in distributed computing, and consensus standards. Indeed, a valid question for all scientists is how Medline, PubMed and similar public services, for all their much vaunted qualities, measure up to current mainstream content management standards in industry. PubMed Central has now dissented from the central PLS proposal and decided that, while it requires participating publishers to deposit material with PMC for indexing, publishers can choose to allow viewing of full text via links to their own sites.

Change in the models for scholarly publishing is inevitable, and is badly needed. But perhaps functionality and people's needs are more important than the issue of cost. What do scientists consider most lacking in the current system, and what is at the top of their wish lists? In what way could scientific information be better handled so that they can work more easily and efficiently? Do use the forum to let us know.

We believe it is time to explore the many dimensions of these issues and debate them fully. The way we have chosen to do this is to invite leading representatives of the main groups of stakeholders and observers -- including libraries, promoters of free access, non-profit and for-profit publishers, database publishers, digital libraries, online-repositories, economists and people at the forefront of technological advance -- to express their views in 1,000-word articles. While we don't expect to reach any firm conclusions about where scientific publishing on the Internet is heading -- something we can all only guess at -- we do aim, in this comprehensive suite of articles, to examine some of the key factors that may determine the future.

We also strongly encourage readers to contribute their thoughts and opinions and proffer useful facts, and will consider publishing these contributions in the forum. The forum will be moderated by Declan Butler and Tony Delamothe, web editor of the British Medical Journal, which is making its content freely available on the Web on publication, both on its own site and on PubMed Central.

In short, we hope to help identify some of the best opportunities offered by the Internet, and see what the best public and private strategies might be, in economic and other terms, to ensure that science reaps the most benefits.

XML Within the Enterprise

2008-10-08T14:56:00.000+07:00

The last four decades of the twentieth century witnessed the birth of the Computer Age. Computers have become an essential tool for nearly every corporate worker. Personal computers are now found in over 50 percent of U.S. households, and with this proliferation has come the explosion of the Internet. The Internet has not only changed the way consumers gather information and make their purchases, but it has also completely changed the way corporations must do business.

Today corporations must be able to respond quickly to market pressures and must be able to analyze large quantities of data to make appropriate decisions. To be of any use to the corporation, this data must be accurate, relevant, and available immediately. As we will see in this tutorial, a Digital Nervous System (DNS) will provide the corporation with a computer and software infrastructure that will provide accurate, relevant data in a timely manner. One of the most important elements of the DNS is the movement of data. In many circumstances, the ideal way to move this data will be in Extensible Markup Language (XML) format.

XML can be used to create text documents that contain data in a structured format. In addition to the data, you can include a detailed set of rules that define the structure of the data. The author of the XML document defines these rules. For example, you could create a set of rules that can be used for validating Microsoft Exchange email documents, Microsoft SQL Server databases, Microsoft Word documents, or any type of data that exists within the corporation.

An industry initiative called BizTalk, which was started by Microsoft and supported by many other organizations such as CommerceOne and Boeing, provides a standard set of rules that are agreed upon by different corporate communities and individual corporations. These rules are stored in a central repository and can be used to build standardized XML messages that can be sent between applications within the corporation and to applications belonging to the corporation's partners. Both large and small corporations can benefit from using these XML messages because it allows them to do business with a wider range of partners.

XML can do a great deal more than just move data. Data can be included in an XML document and then an Extensible Stylesheet Language (XSL) page can be used with the XML document to present the data in Microsoft Internet Explorer 5 (and hopefully other Web browsers in the near future). Using an XML document and an XSL page allows Web developers to separate data and presentation. tutorial 2 will examine why this technique is essential for corporate Web development.

Another initiative, the Simple Object Access Protocol (SOAP), enables you to use XML to call methods on a remote computer on the Internet, even through a firewall. The SOAP initiative is being developed by Developmentor, Microsoft, and others. For more information on SOAP, visit http://www.develop.com/soap/.
BizTalk, Internet Explorer 5, and SOAP address three of the most important issues facing corporations today:

Creating standardized messages that can be moved inside and outside the corporation (BizTalk)
Separating data and presentation when building Web pages (Internet Explorer 5)
Calling methods through firewalls and between different platforms (SOAP)
The focus of this book will be on the features of XML and how it can be used to address these three issues.

Learn About Furnace Torches, Gas Torches, And Soldering Torches

2008-06-14T17:56:00.001+07:00

Metal Casting provides the hobbyist with a great way to create personalized parts and pieces that may otherwise be unattainable or far too expensive. Casting is an ancient art that is still is use to this day by major industries to artists to those with backyard foundries. This skill is a valuable one that promises to provide the hobbyist with a rewarding past time. Most hobbyists begin their casting careers with a modest sized furnace to fit their most basic needs. Within a few months, the hobbyist might find that the furnace has grown and that they are casting at every chance that comes along. Don't worry, this is completely natural.To say that metal casting is addictive is an understatement. Metal casting provides a way for an idea to materialize through molten metal.

This is perhaps one of the greatest parts of the entire metal casting process like seeing what was once just sketches solidify from liquid iron, or whatever metal is used. All the metal caster needs is an idea and red hot liquid metal.The furnace is the pride and joy for the metal caster.

Most will construct their own furnace tweaking the design here and there to better suit their needs. Many home foundries are based on home made furnaces and if constructed correctly can prove to be highly effective. The crucial part of the furnace is the furnace torch. The torch brings the heat, incredibly high heat, and without it that chunk of metal would just sit in the crucible and never see life as something new and exciting. Except as a paper weight; a very ugly paper weight.When searching for an appropriate casting torch the hobbyist will need to take several things into consideration. The size of the furnace, and what metals you plan to use are chief among the considerations. Many casters will use a torch that uses propane gas as it provides enough pressure and heat to melt most metals. If the hobbyist plans to use natural gas like the kind that is provide in households they may find that the pressure is just not enough and the desired temperatures will not be reached. The same is true for Butane. While natural gas and Butane can be used, propane seems to yield the best results. Oxyacetylene torches are a favorite with many casters especially for casting iron.Price is yet another consideration. While it may be possible to rig a casting furnace it is not always advisable. Torches can range in price from $40 to several hundreds of dollars depending upon the size, the use, and accessories.Many jewelers are able to use small independent casting torches but when dealing with metal casting in furnaces you will need to use a torch that can be mounted and used in such a fashion. Many think that just because you need a furnace torch you are going to need a large furnace. This is simply not true.

A small furnace and furnace torch can produce enough heat to melt aluminum, iron, and a number of other metals. One of the furnaces functions is to help the flame reach optimum temperature and in the case of Reverberatory Furnaces, a furnace torch is an absolute requirement.Casting torches can be found in some hobby shops and in hardware stores. Several online shops also sell torches for the hobby metal caster. When buying a torch hobbyist should shop around in order to find the best deal. Always use caution when dealing with a furnace torch.

It may seem an obvious thing to say but when it comes to a notebook computer the battery is the thing that really makes it work. Many people know this, but they forget that the battery only has a certain life span, and at some point you'll probably need to replace it if you want your notebook to keep working at the performance level that you require. This article will look at some of the considerations you need to bear in mind when you're looking to find a cheap deal for your laptop battery needs.
The first thing that you should remember is that you need to exercise care when you're looking for a battery at the cheap end of the market. One of the first things you need to bear in mind is that the shape and the overall design of the battery needs to fit in with the notebook you have. For instance, a cheap battery pack that you bought for a Toshiba notebook may not fit in with the overall design, and so when you go to buy a battery for this make, or any other make for that matter, it is a good idea to take the laptop along with you to the store and make sure that it definitely fits in the housing provided.
The second thing that you need to make sure is that the size of the battery is not such that it will short circuit the laptop itself. You can do a lot of damage to the internal mechanism of a notebook by choosing the wrong battery size and this is something that should be avoided at all costs.
Another thing that is a major consideration when you buy a laptop battery is that the voltage is absolutely correct for your particular model. There are many different types of computer accessory on the market nowadays, and some of them may be made in places where manufacturing standards are not as high as those in others. Make sure that the voltage is just right, because the wrong type of voltage can really do some damage and you could end up completely ruining your laptop all for the sake of buying the cheap battery.
When you go to buy a battery for your laptop make sure that it is one which is being manufactured by a company that is recommended by the actual makeup of the laptop itself. In this way you will avoid any kind of complications which could end up to be an expensive mistake.

2008-01-27T18:38:00.000+07:00

A few tips to find the best computer buy!
Computers, computers, everywhere!! How to find a great one without over paying?
1. Research what kind of computer you want. Once you decide which brand or brands and what components you want. You may want to go look at them in a store and see which ones feel right to you. Write down the model # and brand of each computer you would be interested in purchasing.

2. Places like Circuit City offer a price gaurantee, however you will have to deal with rebates.

3. If you enter the exact model and brand into the google search engine it will come up with a list of stores and their prices. Also try Amazon.com, www.overstock.com, www.everyprice.com. These will give you a list of places to buy the same item at different prices.
Remember its more important to make sure you buying the type of computer you want rather then the price of the computer.

How To Use Inkjet Printer Ratings To Choose The Best Inkjet Printer For You

2008-01-09T19:33:00.000+07:00

How To Use Inkjet Printer Ratings To Choose The Best Inkjet Printer For You by John Snyder

In the advancement of technology comes the need for information. Thankfully there are numerous websites out there that offer comparisons, reviews, and ratings for the different technology products. In particular you can find inkjet printer reviews from tech magazines and websites which not only offer consumer reviews but also professional experience and hands-on product experimentation. However, with all these reviews and information, where can you find a comprehensive compilation of everything? There is a website called Consumer Search which provides this.

Consumer Search provides a collection of consumer and expert from places all over the web including magazines such as PC Magazine, MacWorld, and Consumer Reports to consumer reviews at CNet, Trusted Reviews, or Amazon. Consumer Search provides complete information on inkjet printer ratings from details about the experts reviewing the products, where to buy the products you're searching for and listings of the top rated products. Consumer Search, if you will, is like a review of the review that products get. So not only can you see what the original experts are saying, but you can see if those experts have merit or are just spewing ad copy in order to get people to buy them. It's similar to getting a second opinion on a doctor's diagnosis.

If you're using individual sites to get inkjet printer ratings, then keep in mind that there is a certain amount of salt that needs to be considered. Sometimes reviewers don't always put in the correct rating when they review. I've seen glowing reports on a product that was only give 1 "star" and horrible reviews which give the product 5 "stars". The real meat of the product information is in the reviewer's description, not so much the actual rating. Plus certain consumers look for things that may not be important to you, and thus the product receives a lower rating. So it's a good idea to make a list of the things that you need when looking for a product. Do you want the printer to be able to do duplex printing? What about the software required for install? What type of operating system do you have? Do you care how much room the printer takes up? Do you plan on printing mostly in color or in black and white? These all will give you a basis of comparison when reading the ratings other people have given a product.

Another thing when considering ratings is that people are notorious for leaving bad ratings for things that aren't about the actual performance of the product. I've seen poor ratings because a box was damaged, the sales person at the store was rude or inattentive, or because the consumer didn't like the logo of the company. People's opinions are just that, and sometimes it isn't relevant to what they're asked about.

What Is Regression Testing Software?

2008-01-04T18:29:00.000+07:00

What Is Regression Testing Software? by Terry Edwards

Regression testing software is a software series that is designed to help isolate issues that have arisen with software on the hard drive that was working fine, yet suddenly developed a problem. Essentially, the software works its magic by taking a look at diagnostics and backups from previous periods when the problem was not present, then compares the data to that of a current diagnostic. This simple process can often supply valuable clues about what has changed and created the operational issue.

The beauty of regression testing software is that it can identify problems with a number of different origins. For example, the software may be able to pick up on a local reason for the problem, such as some new virus or bug being introduced to the hard drive and becoming embedded in one or more of the files used to drive a program. In other cases, the regression software may uncover some factor that activated a bug in the software scripting that remained dormant until something caused it to activate.

Even if the origin of the issue is not local, there is a chance that testing software can still help isolate the problem. To illustrate, if one program interfaces and writes to a different database, and in the process creates some sort of a change, that change may in effect break some aspect of the receiving database. Until the change is corrected, the performance of the receiving database will be erratic at best.

Generally, regression testing software can isolate a problem, but does not have the ability to automatically fix the issue. However, knowing what is causing the issue makes it possible to select the right tools that can be used to correct the situation, and restore your hard drive and all the loaded software to the same level of efficiency that was enjoyed before the problem began.

Cool Designs In Consumer Electronics

Cool Designs In Consumer Electronics by James Brown

Most consumers own several electronic devices that have features that perform the same function. This is because consumer electronics are designed to blend in with the needs that consumers have and are marketed solely on one feature and the other features tend to blend into the background. A cellular telephone will include features such as calculator and calendars, but since these consumer electronics are sold individually, there is little talk about duplicated features in any magazines.

Consumer electronics like personal digital assistants are designed to perform tasks that are identical to tasks performed by larger devices but are used more because they are portable and can be enjoyed in many settings where the larger device will seem inconvenient. Many people will own personal computers and use the connectivity devices to download music to the handheld consumer electronics such as MP3 players and PDA's, but they will enjoy the storage space found on the computer and store musical files until they are needed.

A person has the option of installing global positioning devices into the dash of their automobile or using these consumer electronics from portable devices such as PDA's. Some computer software programs will serve the same purpose and a person will find that they can use the internet search engines to find websites that will perform exact distance calculations from one place to another. All of these consumer electronics will perform the same task but consumers are given a choice in which one they want to use and most users will consider the cost of using each method.

Some people use consumer electronics to help with mathematical calculations. A handheld calculator is very useful to a budget conscious shopper, but will prove to be an invaluable tool for someone who is performing intricate equations for algebra. Some users will need consumer electronics while at work because buying materials for a job site will require a building contractor to know the square root measurements of all building surfaces.

Computer software can be used to calculate the cost of every home remodeling project and consumer electronics like flash sticks can be used to store the files safely until they are needed. Computer technicians can use these devices to store many files that are needed for completing compute repairs, and other consumer electronics can be used to verify if electrical connections are energized or not safe to work on.

Other consumer electronics will make tasks simpler and reduce the cost of building projects. Electronic devices such as stud finders allow building contractors to find objects behind drywall that are not visible with the naked eye. A contractor might need consumer electronics such as heaters to make paint dry faster. When the building is finished, the occupant will rely on other electronic devices to maintain a comfortable temperature throughout the building.

While the design of consumer electronics is angled toward accomplishing a specific purpose, many devices can be used to accomplish a variety of tasks. Electronics are meant to simplify life and serve as forms of entertainment outside the home. Radios are one of the consumer electronics that can provide safety information if it is tuned to the right channel, or it can help keep drivers awake while driving for hours on a busy highway. Some consumer electronics are capable of putting drivers in contact with fire, police or ambulance companies in the event that an accident occurs on the roadways.

HP Inkjet Printer Review

HP Inkjet Printer Review - Find The Right HP Printer For Your Needs Without All Of The Marketing Hype by John Synder

HP has really become of the leaders in home based technology from their personal computers and laptops to being the folks that brought all-in-one printing into the home. Back when the internet first began gaining popularity and Microsoft Works was still the word processor of choice I owned a Hewlett Packard and swore them off ever since. However, that changes a couple of years ago when I purchased my first all-in-one printer which did photos. I fell in love with the crisp quality of the printing, the ability to use the machine without needing to hook it up to a computer but I hated the bulkiness of the required software, especially on my Macintosh. If I would have taken a minute to look at the hp inkjet printer reviews out there instead of making an impulse buy, I probably would have chosen a different model. We live and learn right?

In earlier days one would have to spend time searching Google and other sites to find reviews for hp printers, but it seems now the major manufacturers have caught on. Upon reviewing HP's website I noticed they provide their own customer review capabilities as well as giving potential buyers the ability to check out other review sites, like Cnet, and showing what rating those sites have given the product. All in all it's a pretty handy feature for the hp inkjet printer reviews to be right there on the manufacturer's page.

However, just in case there are several other sites still accessible with product reviews. Not to insinuate that HP is being Machiavellian but no company wants to display reviews and ratings that paint not so beautiful pictures of their products. So just be sure to check around and don't be suckered into buying an hp printer based solely on the reviews. Also be sure to read the hp inkjet printer reviews thoroughly and decide if the pros or cons the other consumers listed fit your specifications. While a Macintosh user may have problems with the software, like I did when I bought my HP printer, if you use Windows as an operating system then in all likelihood that won't be something that affects you. If a user gives the printer a low rating because it's slow to print black and white, but you want the printer for photos then that review isn't necessarily relevant and their recommendation shouldn't be held as highly in your mind.

While consumer ratings or hp inkjet printer reviews can be helpful to see how the population responded, it's always a good idea to get reviews from experts who have more understanding of what a printer should be capable of and what they're dealing with. Sometimes the population feels like a piece of technology should be able to perform a task much better than we are actually capable of making, or their "forever" is actually a fairly standard time period.

What is the Best Way to Remove Spyware

What is the Best Way to Remove Spyware

Trying to find a file on your computer that is invisible can be a headache in itself. Trying to find this same file that is causing you so many problems is downright aggravating. You could be spending more time enjoying your computer or even more importantly working from your computer than trying to find the culprit that keeps opening explorer every time you open outlook express.

With the time and aggravation that is taking its tole on you it is time to act on this intruder once and for all. First of all, uninstall all programs that are not essential to you. This mean that alarm software you downloaded to wake you up but could never get to work right. And yes, get rid of some of you search bars also. These are breeding grounds for spyware and the likes.

Once you uninstall the unwanted programs from you add/remove console, begin by cleaning your hard drive. Use the native one that comes with windows or download your own. I personally like system mechanic, but that is just preference. Once you know that a lot of the junk files are cleared from your computer, It is time to run an anti-virus program. Any will do that is up to date. Key being up to date. After this is done it is time to attack the menace from within. Your adware, spyware, malware or whatever you want to call that gremlin.

Start by downloading an anti-spyware program. Here is some reviews on a couple of good ones, http://mertod.bezoogle.com/pp/adware/ , Then once you have the right one for you download it and get the latest update. ALWAYS ALWAYS updater your spyware software. Updating gives new definitions and uses the old ones as well. So what might work today might not work tomorrow unless you update.

After you update it is time to run your spyware to find that nasty adware. Exit all of your windows programs first. Get down to the bare desktop. If you have to go to task manager do cnt + alt + del. Close any know programs that are open. The reason you close all the programs is some spyware removers cannot clean a file that has adware on it if it is open. It will not scan it. So be safe and close every thing you can. It is also good to exit from the internet. This keeps the spyware from opening browsers and the likes.

After scanning the drive for spyware I like to rescan. If time permits do so. Also immunize your computer after the scan. This helps the spyware protection software to keep tract of what it found to be suspicious. After you have run the scan, restart your computer and repeat the scan again. Let the spyware remover rescan your computer until all accounts of the adware are gone.

If the problem is so bad that you cannot get rid of the spyware or even worse your computer begins to act strange or be unresponsive it is probably time to take it to a local technician. Hopefully we can take preventative measure before we reach that step in getting some spyware protection and prevention on your machine as soon as possible. Once you are infested with spyware, your computer and your life become a pain when it comes to getting the most out of your computing.

Hopefully you will take the steps to protect and prevent unwanted spyware from taking over your computer and causing you a massive headache in the process. Adware and spyware are major enemies to your computer and should be removed immediately. The more time without a spyware remover on your computer the more time the spyware can hide and eventually ruin your computer from inside. Take the steps to remove these unwanted visitors from your computer.

Spyware - Don't Fight It By Yourself

Spyware - Don't Fight It By Yourself

There are many reasons why spyware could be very annoying if it went onto our computers. Spyware gets on your computer and acts as a spy for marketing and advertising companies. They will go into your private life and find out where you go to surf and what sites you like to visit. As soon as the spyware gets on your computer it will start sending information back to the site it came from. It acts like a parasite as it sits on your computer and works in the background reporting everything you are doing.

Spyware can creep into your computer and record your web browsing history and even scan documents on your hard drive. This is all done quietly in the background without your consent. It can often be used as information for advertisers who will then simply annoy you with ads. This type of spyware though it not directly harmful can clog up your computer�s resources and slow the programs down. Though it does not perform any illegal act it does affect your life and causes and great deal of annoyance.

They are powerful and so can they hack the entire memory of your computer by scanning history and also by scanning the documents present in the hard drive. These works are done behind the curtain and you are not to get alerted for all the spying done by it. Later you will be annoyed with several ads by the advertisers who aimed at collecting information regarding your browsing pattern. They could have an adverse effect on your computer by clogging up the resources and thus slowing down the programs as such. They do not prove to be illegal but it does affect the over all performance of the system.

Spyware is considered to be the perfect way in sending promotions and products to the appropriate people by the advertisers. This would help the advertisers understand about the products you are in search of, so that they can send related product information to your system. You can categorize these promotions to be in the junk items if you are not interested. Some of the Spyware can also change the settings of the computer linked with the homepage. It can automatically change the homepage of the system to the website that you would like to search for. You can also see pop up adds on your system which is stated as another Spyware attack.

Some spyware is even dangerous. Not only will it collect information on your web surfing habits but it can steal passwords or financial details! This is especially dangerous for businesses. They can make attempts to intercept when sending passwords or credit card numbers and steal the information and perform some illegal act.

Spyware are removable and by using the right spyware removing soft ware you can remove most of the spyware programs form your computer. Some of this spyware are however difficult to remove. You can directly down load spyware programs using internet and some of these programs have the capacity not only to remove spyware from your computer but also to prevent spyware from entering from your computer.

Windows Task Manager is not enough for complete protection of your system as Spyware remains to be hidden from them. The Spyware detection software�s can really help you in detecting the Spyware running in your computer. Several anti-virus programs also detect spywares and protect from further Spyware attacks as they come along with antispyware programs.

CNC Control Computer

2007-11-18T18:40:00.000+07:00

CNC Control Computer

The Control Computer generally resides in the shop somewhere near the CNC machine it is controlling. Control Computers don't have to be the top of the line, every bell and whistle type of computer. These are the workhorses. Save your money for a good design computer. You will save much more time having a fast computer for your designing.

A control computer doesn't have to be that powerful for a few good reasons. It doesn't have the workload. It takes G-Code and turns it into signals that it transmits to the Machine Controller. Turning G-Code into signals is not that labor intensive for a computer.

I have used multiple types of control computers. Everything from a 486 DOS running "$30 special" to a modern Dell with Windows XP. I have yet to try one with Vista. I will keep you posted. Generally I like to find a good used computer for a couple hundred bucks, wipe the hard drive and only load the control software onto the machine. That way you know what you have.

There is another good reason you don't want to spend a lot of money here. This computer will usually be located in the shop. Dirt will be located in your shop. Using logic here, dirt will be located in your computer. If the computer does go belly up, you aren't out your children's college tuition.

Here is my strategy in a nutshell for Control Computers. The dirtier the job, the less money I spend on the computer. My plasma cutting computers are bought in the $40 range. They eat a lot of dust and dirt. I blow them out frequently. My wood routing computers are in the $100 dollar range. My milling machine computers usually are in the $200 range. Truth be told, they all last a very long time if you keep dirt, dust and plasma smoke out of them.

How is the CNC Control Computer used?

The control computer has the control software loaded on it. You start up the control software then load up the CNC Program you created. When you do this, the G-Code will be visible and ready to go. Once you prep your CNC Machine and zero it out, you can begin your "cycle." A cycle is usually completing one CNC Program, which is a machining sequence. You will also hear the term "Cycle Time" on the professional side of CNC a lot more. The quicker you can get the cycle time, the more parts you can make. And yes, that translates to more money.

Back in the good old days of Home CNC, everything was transferred on a disk. Now I have seen people include their Control Computers on their home computer network and transfer the files needed wirelessly. At a very minimum, get a good jump drive and transfer things back and forth that way.

CNC has become a very popular hobby and more and more people are starting to hop on the band wagon of CNC. Its a fun hobby and easy to do from your very own home with just a little elbow grease and creative mind.

CNC Process Overview

Quick Explanation of the Process

This is how I view CNC. I break it down into simple steps that I can remember. Now, they all interact, but it is good to keep them in boxes for simplicity sake. I also like to keep them in a logical, progression type order. Here they are: Design, CAD, CAM, Control and Machine.

Today you are going on a journey. You are going to learn about the basics of CNC. I hope you are as excited as I am about this topic.

I have been using CNC equipment in my home shop for six years now. The technology gets better and better every year.

The software gets better every year. At one time large companies could only afford this technology. Now there are hundreds of thousands of these machines working in garages like yours and mine.

There are basically five elements to a CNC Project that you need to know:

Design - thinking and planning what you want to build CAD - translating it into the computer CAM - converting it into machine language Controlling - directing your machine's motion Machining - building the part to specifications

These five elements are really the building blocks to a CNC project. As you see them above, that is generally the order people associate them in. For example, you can't control until you have a design. You can't use your CAM software before your CAD software. One of the main things you need to address is how these elements interact with each other.

Right now this may seem confusing. Over time, it will seem very basic. The more you use these elements with one another, the more their order will become second nature.

Note: The A-axis is the rotational axis. Why is it called that? I don't know. It is also sometimes called the B-axis. I have even heard it called the W-axis. A-axis is the rotational axis around the X-axis. B-axis is the rotational axis around the Y-axis.

Buying a completed CNC Machine

If you purchase a CNC machine outright, it will have a machine controller as part of the package. Everyone does it a bit different though. Some try to make it a black box that only they can fix. Other use commonly used components so you could repair it if need be. You will just have to ask the manufacturer and see what they say. My experience says they usually tell you that it uses common components that you can get anywhere if needed. If something goes wrong, it seems you can only get the part from them. You will have to decide.

Internal Machine Controller Parts

There are many different electrical components that go into a machine controller. I won't pretend that I am an expert on this. Actually, this is one of the components I buy pre-made so I don't have to do it. If you are an electronics junkie you could build your own. I know where my skills are at and it isn't in assembling and understanding electronics.

How To Prevent Your Computer From Being Slow

2007-11-17T20:51:00.000+07:00

How To Prevent Your Computer From Being Slow

One of the most common complaints that we hear from PC users is the slowness of their PCs. You must have had the same problem with your computer some time or the other. And generally the answer we get to this problem is that perhaps you have stored way too many files and documents on your personal computer, which makes it slow down gradually. This is indeed a valid explanation for a slow computer; however it is not the only reason for a slow computer. Other than this something very vital which you need to look into is the registry of the computer.

The registry or the registry files in the computer keeps stock of everything-information and settings of all the software, operating system software, hardware and every single file and functions running on the computer system. The registry files have to be maintained in proper order; otherwise once any of the files go awry, the computer faces problems in functioning smoothly and might even hang up. The computer requires starting up any particular software by looking into the registry files. In case the registry file is absent or not in its proper shape, the computer is liable to stop running the given software. This in turn slows down the computer generally. The slow computer is unable to do anything with the software. In such a situation there is the possibility of the computer hanging or getting locked up. This is where you need to take care that the registry files are in working order, or fixed properly when the need be.

The basic thing you need to have in order to fix your registry files is registry repair software. You can get the very best standardized registry repair software and use it on your personal computer. The registry repair software is imperative for such a situation; you cannot repair the damaged registry files otherwise. Using the registry repair software helps because it points out the number of files that are corrupted and need to be repaired. Then you can give command to the registry repair software to fix each and every registry file and restore them to their original configuration. The entire process is surprisingly simple, and can be done in only a matter of minutes. And because it is a relatively simple process you can check your registry files from time to time. For instance if you use the registry repair software once a week it is enough to ensure that the registry files are in proper shape.

A slow computer is a very common malaise in computer systems. As mentioned earlier, storing an excessive amount of files and folders may also cause your computer to operate slowly. In such cases we find that the speed of the computer decreases; a file or folder might take more time in opening than it earlier used to or your CD writer might take an unusually long time in writing material to a blank CD. But you should not forget the importance of registry files and how you can keep them in perfect order with the help of the registry files repair software.

But for your knowledge, the granny is on her trip to somewhere else. So what is sounding so dubious? You may be frightened. Kindly pay a vigil attention to your computer. You may find the alter ego of the snoring granny. The cause of snoring is the dust that has built its permanent hill station in your system. Dust chokes the vents behind your computer and forces it to give you the glimpses of the snoring granny. Do you know the fact that dust not only makes your computer to behave dubiously but also makes the CPU to heat up? Heat is the most potent enemy of your computer which causes component failure. So clean computer regularly and minimize the threats which affects the performance and efficiency of your computer.

Tools required for cleaning computer

You need simple tools to clean computer and you can do the cleaning at home with the help of these tools. The tools required are a screw driver, can of compressed air, cotton swabs, rubbing alcohol, anti static cloths and water. You can find the compressed air can at computer dealers. Never use cotton ball in place of cotton swabs when you clean computer. It may not provide the desired result.

Turn off the computer and disconnect the power supply when you start to clean computer. With the help of the screw driver open the case opposite to your mother board. Do not touch the inside parts of computer frequently. Keep your fingers away from the cards and cords when you clean computer.

Then blow air from the compressed air can around all the components of your computer. The nozzle of the can should be four inches away from the machine. The inside cover should be wiped with a light moistened cotton cloth.

After you clean the inside of the case, start to clean the outside. Dip the cotton swab in rubbing alcohol. Then give a gentle wipe to the outer side with this cotton swab. After the outside is cleaned properly, clean the keyboard. Keyboard has the maximum chance to gather dust as they have the maximum exposure to the outside. Clean the keyboard with the help of the cotton swab. While cleaning make sure the cotton swab is damp not wet. If it will be wet, further problems can occur.

Clean the monitor with the help of the moist paper towel softly. While cleaning, do not spray liquid directly on the screen. Spray the liquid on the cotton cloth and clean the monitor with that cloth.

After cleaning all the equipments, connect the power supply only when they are dry. Perform this cleaning once in every three months to make the life span and performance of your computer satisfactory.

Medical Document Imaging Transforms Medical Practice

2007-11-16T10:39:00.000+07:00

Medical Document Imaging Transforms Medical Practice

Medical document imaging can transform medical practice by capturing patient charts in an electronic form. Unlike paper charts, practitioners can access electronic charts with utmost ease, by clicking a mouse (or touching their PDA). Whereas they had to wait for the paper chart earlier, now the chart is available to them instantly.

The patient chart is the key document in healthcare. It communicates the specific information that doctors need. Even if the patient moves to another city the patient chart can be accessible by doctors there over the Internet.

Lab results can also be scanned immediately into an electronic document, and made available within hours to doctors. Even if the results are stored in another hospital, doctors can access it by dialing to the hospital.

This kind of scenario is very different from a paper-based one. Paper charts and lab results have to be physically moved around. Doctors have to make a request for the documents and then wait while it's being located and transported.

Lost charts are a frequent problem when large numbers of paper-based charts have to be managed. Frequent retrievals and transportation could not only increase the risks of loss but also damage the records. Even otherwise, legibility is typically a problem.

E-Prescibing, where a doctor uses a PDA to check drug databases and make an electronic prescription can solve the legibility problem. Medical document imaging solutions often come with e-prescribing solutions also.

How Medical Document Imaging Reduces Costs

Paper-based charts require storage equipment and space. Dedicated staff are needed to attend to the paper-handling, filing, maintenance, and retrieval tasks. The problem is compounded because charts can be misplaced or lost and time might be spent on fruitless search.

Where the chart has to be sent to another location, courier charges are incurred, as against the Internet access possible to electronic records from anywhere.

Even within the same practice, the records can be accessed from any of the networked hospitals, clinics, or even from the homes of practitioners.

In a computer-based system, the paper charts and reports can be shredded once they've been captured by the medical document imaging system.

Other benefits of Medical Document Imaging System

Where doctors have to consult one another, the same patient record can be simultaneously accessed and studied by the doctors involved from their workstations.

Security and confidentiality can be improved if paper records are destroyed once they are done with. Access to the electronic records can be strictly controlled.

Medical document imaging is easy to install. It is easy to use, users can be trained in little time and regular imaging operations can start within a month or so.

Conclusion

Medical document imaging clearly brings out many of the advantages of document imaging systems. Patient charts and lab reports are scanned into the system, which can then be accessed by doctors from their workstations, or transmitted to distant hospitals if needed. Costs are reduced because paper handling and storage requirements are eliminated or minimized. Security and confidentiality are improved through more effective access control.

Free Mp3 Download Provider

Almost everything is available in the Internet nowadays, articles, news, books, softwares, applications and the most downloaded MP3 song provider. Downloading free MP3 in the internet requires you to install a file-sharing software. One of the infamous MP3 file sharing software is LimeWire. LimeWire is a peer-to-peer file-sharing client for the Java Platform, which uses the Gnutella network to locate and share files. Released under the GNU General Public License, Limewire is free software. It also encourages the user to pay a fee, which will then give the user access to LimeWire Pro.

Here's a quick reference to its features and system requirements:

Written in the Java programming language, LimeWire is able to run on any computer with Java Virtual Machine installed. Installers are provided for Microsoft Windows, Mac OS X, and Linux. Support for Mac OS 9 and other previous version was dropped with the release of LimeWire 4.0.10. It offers the sharing of its library through Digital Audio Access Protocol. As such, when LimeWire is running, any files shared will be detectable on the local network by DAAP-enabled devices (eg. iTunes).

* Ease of use - just install, run, and search.

* Ability to search by artist, title, genre, or other meta-information.

* Elegant multiple search tabbed interface.

* "Swarm" downloads from multiple hosts help you get files faster.

* iTunes integration for Mac and Windows users.

* Unique "ultrapeer" technology reduces bandwidth requirements for most users.

* Integrated chat.

* Directly connect to a computer.

* Browse host feature--even works through firewalls.

* International versions: Now available in many new languages.

* Automatic local network searches for lightning-fast download.

System Requirements: Must have the Java2TM Runtime Environment, v.1.3.1 (JRE), 64 MB RAM

LimeWire is must-have software of MP3 enthusiast. It provides unlimited downloads and most specially, it is for free. Another way to download free MP3 is the use of µTorrent software. µTorrent is BitTorrent software that allows you to download from torrent files. It is Micro-Sized Yet Feature Filled. Most of the features present in other BitTorrent clients are present in µTorrent, including bandwidth prioritization, scheduling, RSS auto-downloading and Mainline DHT (compatible with BitComet). Additionally, µTorrent supports the Protocol Encryption joint specification (compatible with Azureus 2.4.0.0 and above, BitComet 0.63 and above) and peer exchange. Resource-Friendly, µTorrent was written with efficiency in mind. Unlike many torrent clients, it does not hog valuable system resources - typically using less than 6MB of memory, allowing you to use the computer as if it weren't there at all. Additionally, the program itself is contained within a single executable less than 220 KB in size. µTorrent also has support for localization, and with a language file present, will automatically switch to your system language. If your language isn't available, you can easily add your own, or edit other existing translations to improve them. Actively Developed and Improved, the developer puts in a lot of time working on features and making things user-friendlier.

It can be used to download single mp3 files but it can also be used to download albums or song collection of artists. µTorrent is for free and you can download it at its official website. A detailed guide on how to use µTorrent is also available at their website.

What Is The Difference Between A Worm, Virus And Trojan Horse?

2007-11-16T10:33:00.000+07:00

What Is The Difference Between A Worm, Virus And Trojan Horse?

Tips and recommendations for protecting your PC...

Most of us don't make a real difference between worm, virus and Trajan Horse or refer to a worm or Trajan Horse as a virus.

All of us know all are malicious programs that can cause very serious damage to PC. Exist differences among the three, and knowing those differences can help you to better protect your computer from their often damaging effects.

A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. Some viruses cause only mildly annoying effects while others can damage your hardware, software or files. Almost all viruses are attached to an executable file, which means the virus may exist on your computer but it cannot infect your computer unless you run or open the malicious program. A virus cannot be spread without a human action, (such as running an infected program) to keep it going. People continue the spread of a computer virus, mostly unknowingly, by sharing infecting files or sending e-mails with viruses as attachments in the e-mail.

A worm is a program or algorithm that replicates itself. A worm has the capability to travel without any help from a person from PC to PC and have ability to replicate itself on your system, so rather than your computer sending out a single worm, it could send out hundreds or thousands of copies of itself, creating a huge devastating effect.

A Trojan Horse is a destructive program that "working" as a benign application ( (like changing your desktop, adding silly active desktop icons) or can cause serious damage by deleting files and destroying information on your system. Trojans are also known to create a back door on your computer that gives malicious users access to your system, possibly allowing confidential or personal information to be compromised. Trojans do not reproduce by infecting other files nor do they self-replicate.

Added into the mix, we also have what is called a blended threat. Blended threats combine the characteristics of viruses, worms, Trojan Horses, and malicious code with server and Internet vulnerabilities. By using multiple methods and techniques, blended threats can rapidly spread and cause widespread damage. Characteristics of blended threats include: causes harm, propagates by multiple methods, attacks from multiple points, and exploits vulnerabilities. This combination of method and techniques means blended threats can spread quickly and cause widespread damage. Characteristics of blended threats include: causes harm, propagates by multiple methods, attacks from multiple points and exploits vulnerabilities. They are considered to be the worst risk to security since the inception of viruses, as most blended threats require no human intervention to propagate.

Therefore is very important to protect your PC with a good anti-virus software installed on your system with the latest fixes for new viruses, worms, and Trojan horses.

Additionally, you want to make sure your anti-virus program has the ability to scan e-mail and files as they are downloaded from the Internet. This will help prevent malicious programs from even reaching your computer. You should also install a a system that prevents unauthorized use and access to your computer (firewall as well). A good software firewall will protect your computer from outside attempts to control or gain access your computer, and usually provides additional protection against the most common Trojan programs or e-mail worms.

What do you do when your hard drive crashes

2007-11-16T10:10:00.000+07:00

What do you do when your hard drive crashes

If you have lost some data due to either hardware failure or physical damage it is very likely that you will not be able to recover the data yourself. In such a situation you will need to look elsewhere to get your data recovered.

Data recovery is big business and because of that there are many companies offering service. With so many options out there it is important to choose the right data recovery business for your needs. In addition, your data is important so it is also important for you to move quickly.

When trying to choose a service provider, look for one that can recover data due to multiple reasons as well as one with a good track record. An example: They should be able to assist with physical damage as well as general hardware failure. And always check references.

Contact the manufacturer of your hard drive for a list of service providers they recommend. Some data recovery businesses specialize in specific brand of hard drives.

After selecting a service, read the service agreement very carefully. You will need to understand your financial obligations. Some services will only charge full price upon the successful recovery of your data while other services base their fees on the time and attention your situation called for.

Ask for an estimate of the final cost. This will give you the best ballpark figure of your final expense. Although data recovery services can often be expensive, the value of the information you recovered can be priceless.

It is sad, but stories of laptop computers being dropped into water are all too common. Sometimes its a different story, like lightning striking a phone line and causing damage through your computer's modem. In the end it doesn't matter what causes the damage but it does cost businesses thousands thousands of dollars every year.

The price can seam very high when personal finical documents and family photos are at stake. So if your hard drive is ever damaged and you fear you have lost important information then the best thing you can do is to pay the price and contact a professional.

External Drives Data Recovery

2007-11-12T12:25:00.000+07:00

External Drives Data Recovery

A wide variety of failures can propel severe external or physical damage to drives and storage media. When the drive is physically damaged, a greater level of precaution needs to be exercised in order to ensure that the data is still recoverable. To clarify your understanding, external hard drive data recovery means the process of recovering data from external hard drives like USB or Fire wire when the data is neither lost nor inaccessible because of some reason or the other. External hard drive data recovery process comprises the same process followed while trying to recover some lost files. Let's take the example of the ICD-ROMs which may get damaged because their metallic substrate is scratched. Keep in mind that hard disks can suffer any of several mechanical failures, such as head crashes. There can be a case of failed motors so physical damage always causes at least some minimal case of data loss. Most physical damaged drives cannot be repaired by the end users. For example, opening a hard disk in a normal environment is a complete no-no because the dust would obviously settle on the surface. If that happens, that could worsen the damage caused to the platters and complicate the external drive data recovery process even further. The difficulty is that most users aren't experts nor do they have the hardware or technical expertise required to make these repairs. So it is best to opt for data recovery companies to do the job rather than make costlier mistakes that complicate data recovery processes further. Most professionals use Class 100 clean room facilities to protect the media while repairs are being made. How this is done is discussed herein.

The extracted raw image is used to reconstruct data that can be used after any repair of the logical damage is carried out. Once the repair is complete, the files may be in usable form although its actual recovery may turn out to be very incomplete. Some helpful examples of physical recovery procedures include removing a damaged PCB (printed circuit board) and replacing it with a matching PCB from a healthy drive. Other good examples comprise changing the original damaged read/write head assembly with matching parts from a healthy drive, removing the hard disk platters from the original damaged drive and installing them into a drive that works fine. As these procedures are technical in nature, it is best that these are taken care of by professionals and not by untrained persons. When the hard drive is physically damaged, remember that any additional access to the same drive would definitely corrupt data. This would make it much more difficult to get information back. Note that if the damaged drive happens to be the drive containing the operating system, don't consider trying to boot the drive. But for a desktop, there is less cause for worry as all you must do is disconnect the boot drive and replace it with a new drive. A tip for you is that do ensure the drive can accommodate the image of the current drive.

Next, an operating system can be easily installed on the new drive. You just need to reconnect the old drive or put it in an external case and connect via USB or FireWire. In creating a new primary drive, you would be able to run the disk imaging software from the new drive. This way, you would be able to prevent the need for any writing to the old drive. If your hard drive works in a RAID system, you need a service that specializes in RAID data recovery as it wont be a good idea to do it on your own. When a hard drive is prepared for its initial use, the drive is magnetized. This is done with a number of self-synchronizing magnetic bits. The purpose of this self-synchronizing structure is that, no matter where the hard disk is in its rotation cycle, the hard drive controller would be able to speedily touch down as to which of these bits represent no-man's land, which of these actually represent the drive's formatting, and which represent critical data. Various situation based examples were discussed to clarify your queries on external data drive recovery. So do utilize this informative discussion sometime when you come across data problems on your external hard drive.

Data recovery services and professionals

The world of data recovery is somewhat a big mystery for most consumers and even for some IT professionals. This is largely because hard drives are complex devices and their technological specifics are not generally well known. No wonder, the market for data recovery services and professionals spanned a stunning, astounding figure of over US$100 million. This reflects how rapidly the industry for data recovery services and professionals has grown by leaps and bounds. Let's first understand what brings about data loss. Data loss can be caused by a combination of factors which often requires professional assistance. The current finding of cloning the damaged, malfunctioning drive and using the cloned version on a new drive as a means to recover data may be helpful but it is best to engage professionals to help you. Coming back to our discussion on causes of data loss, this may also occur if your OS fails to boot or if you get a blue screen error, but this should not give an impression to you that all is lost. These data losses can be caused by bad sectors which stall the drive head every time it tries to read them. If your drive is detected by another computer, there is hope of copying your data prior to total failure. There can be situations where you have a brand new hard drive but you still suffered data loss. Sometimes a faulty component or a faulty installation can also lead to data loss. Sometimes it can be due to sudden electric failure to which the brand new hard drive may not be immune. So there are countless causes that can lead to data loss. One of the most often asked questions that you would naturally want to ask if you have suffered a loss of data is, "how can you help me to retrieve or recover my lost data?" Do not worry. With the right blend of knowledge, experience and tools, it is possible for a competent data recovery professional to carry out a recovery 'surgery' for your data loss problem. The data recovery services and professionals are extremely well equipped with an amazing array of software, hardware and other technologically advanced tools to help recovery data. Most of the data recovery labs utilize a combination of the best and most high quality proprietary software, specialized hardware, and years of valuable experience to recover data after a major crash, or even acts of sabotage. There are also highly trained computer forensic specialists who are competent to handle each recovery to ensure your data will not be compromised during the process of the recovery. Most data recovery professionals are extremely conscious of the fact that your data is sacred and irreplaceable to you, so they handle the issue with great care. The first thing that a data recovery firm would do on receiving a hard drive is evaluate it. They would try to see whether logical recovery is required or not. Most firms of repute do not charge evaluation fees but some firms do so and there are other firms that levy an additional charge of on site support. Perhaps these contradictions simply mirror the highly saturated nature of the booming data recovery industry where it seems to be a dog-eat-dog world. The time frame for data recovery comprises about 5-10 business days for physical issues and 2-4 days for logical issues. In situations where the components are not available, this may extend to several weeks to complete the recovery. The costs associated with data recovery services and professionals vary to a great extent. There would be quotes that range from $300 to $5,000 for standard hard drive recoveries. So before you send your drive for data recovery to any professional or firm, make sure that you locate a company that will give you an up front cost, be it for either a logical or physical recovery. In most cases, you will be able to recover your data through data recovery services and professionals. Go ahead and show your confidence and engage data recovery services and professionals to do their job and ease your tensions!

iPod Data Recovery

There is a lot of bad news nowadays because data is getting lost faster than eve before. This has now become a matter of grave concern because large companies are fighting each other to make profits yet their functioning is getting their profit lines into deep trouble. A large part of our work depends on data stored in computers, laptops and even iPods. The iPod is a great device that revolutionized the music industry. Apple's sleek digital audio device is one of the world's most successful tech gadgets that crossed whopping sales of more than 3 million units since the year 2001. By making the iPod so tremendously user-friendly, this device has more a customer base of millions and millions of consumers from all over the world. The iPod makes it legal for consumers to access legal music on demand for just a dollar for every song. This means you don't have to go to the store to buy a CD for $15. You can listen to it on your iPod. This is how the iPod became a household name. But from a security perspective, the iPod hasn't created a good impression at all. Thus, the future of iPods doesn't look too bright. Most gadgets like the iPod, when used by professionals, pose serious and severe risks in the context of organizational security and data loss. Thus, it is now an established fact that when gadgets such as iPods are connected to a work PC, this can be extremely risky. A malicious code can easily enter the corporate network and remain undetected by the intrusion detection software or the corporate network's firewall system. Another danger is that the iPod can work as a USB mass storage device and can serve the same role as a USB pen drive so it does have an impact on computer security though Apple never had that in mind. Controlling the access to iPod data and resources is thus essential. There are methods and mechanisms can be used to accomplish this type of access control, but historically they're generally software-only solutions. But most of these are trapped in evolving phases which makes it difficult to attempt iPod data recovery without the help of professionals. Further, most access control mechanisms relating to iPod data recovery seems vulnerable to software bugs and implementation errors. As this may result in data compromise, it is not worth pursuing. In 1971, a paper titled 'Protection' was presented by Butler Lampson where he explained the concept of data protection through the concept of multiple domains of information running on a single host. This idea is mainly that each domain would execute independently and with differing rights that exist for the programs in each of the domains. This great theory was a huge and tremendous inspiration for countless computer scientists who were researching on the subject. This becomes even more significant in the light of the fact that for content providers such as record companies, this idea from Lampson will allow them to ensure that their content is accessed only in a manner of which they approve. For instance, when we refer to a system like the iPod that has these domains implemented, then the files can be read only by trusted and authorized programs. The problem with this protection theory is that it is not always possible to achieve complete control of data with software-only solutions. Most access control mechanisms fall prey to loopholes that severely damage data later on. Another reason is that access control mechanisms can't be manipulated beyond a point as these are so complicated that they require interaction with the user very frequently. No doubt, the iPod is not an entertainment device any longer. In fact, it is a device that can leak information and store information so handle iPod with care and in case of data loss, get help from the experts.

Delete spyware - an introduction to spyware and adware

If you have been around on the internet for a while, you have probably heard about spyware and adware before. These are two different types of programs, but they definitely have one thing in common - they can both end up wasting your time and making it hard to use your computer. In addition, both programs are made by unethical companies with the main purpose of making profit, at the expense of your being an annoyance and taking up your computers processing power.

That said, there are a few fundamental differences between spyware and adware. In order to prevent your machine from getting infected, it is worth having a basic understanding of what these programs can do.

Definition of spyware:

Spyware is a malicious program that is almost always installed without you knowing about it. It runs in the background, silently taking up your computers processing power and hiding in places like the registry. Software like this is designed to "spy" on you, mostly by collecting personal information (often through keyloggers which record your passwords for bank accounts and send them back to another person) and tinkering with personal settings.

Definition of adware:

Adware is a similar kind of program, but with an important distinction: rather than collection personal information, it has the intent to display advertisements more than anything else (this is where the name comes from). Software like this will still try to remain undetected, but it will be more obvious that you have it, because you'll tend to be bombarded with things like pop-up ads once you have it. Companies who make software like this have one main goal, and that is to make money off each computer they infect and display advertisements ti.

If you suspect you are infected with malicious software, you are definitely not alone. Sources vary, but with the rise of programs like this since 1998, it is estimated that a whopping 90% of computers connected to the internet are infected with some kind of spyware. What's also interesting is that many people infected do not even realize that they have damaging software like this on their machine, because it runs in the background and try's to avoid detection.

What should you do if you suspect you are infected? Well, the first thing you should do is get a good spyware cleaner software. There are a number of good programs that you can download free, that can run an extensive scan to see if you are infected. Then, the anti-virus software will try to delete spyware found. No matter what you are doing on the internet, it is important to get protection like this.

Spyware Cleaners and what spyware does to your machine

2007-11-09T20:25:00.000+07:00

Spyware Cleaners and what spyware does to your machine

Spyware and adware can prove to be extremely annoying in a number of ways. Programs vary greatly in terms of damage, and there are is a wide range of malicious software that might just slow your computer down, all the way up to programs that render your computer completely unusable. In order to protect ourselves from harmful programs it is important to know exactly what they can do.

The first thing spyware does is slow down your computer. Why? Well, malicious programs typically have to perform a function like tinkering with your settings, displaying pop-up advertisements or recording your information, and in order to do this they need to use your computers RAM and CPU. Therefore, software may run slower due to adware and other programs taking up your computers resources.

When this happens, you'll often find that your computer takes a much longer time to start up, and it takes a much longer time to open software. It can also cause your computer to completely lock up and have trouble running complex programs that it could otherwise normally handle. The problem increases with the more spyware you get. If you have noticed your computer seems to have become slower and slower for no apparent reason, then there is a good chance your machine is infected.

Other than slowing your computer down, a second thing programs like this do is relay information (this is the definition of spyware, which aims to "spy" on you). This is much more damaging than programs that simply slow your computer down, because it puts all your information at risk. You have probably heard of things like identity theft before. Well, guess what, a very large amount of this arises from cyber-criminals who infect numerous machines.

If you use the internet to order online, then malicious programs running in the background can easily record sensitive information such as bank account numbers and passwords, as well as access details to paypal and other online processing systems. People who make malicious programs and record information like this often sell it to other criminals, who use it mostly for identity theft (and occasionally for money laundering). As you can imaging, this is the most damaging kind of spyware.

How can you protect yourself from things like this? The first thing is to get some kind of spyware cleaner software. This will scan your PC from a database of thousands of known threats, and then try to delete any spyware found.

Adware and how to tell if you're infected

2007-10-29T22:03:00.000+07:00

Adware and how to tell if you're infected

When it comes to malicious programs, one of the most annoying is so called adware. Adware is software that, once installed on your machine, will begin to serve advertisements mostly in the form of pop-ups. Companies who make adware make money off advertisers who pay them each time their ad is served on an infected machine.

Here's some of the things you can do to tell if you have adware:

1)You keep getting pop-up advertisements.

Pop-up ads come in two forms. Either the website you're visiting is serving them, or you have adware on your machine that spawns pop-ups each time you surf the internet. If you go to a website like Google or Microsoft, and you see a pop-up ad, then this is an almost sure sign that you're infected with adware. Pop-up ads can also be served when you just start up your computer, or when you run an application.

2)Your computer is running slowly

Adware will often take up your computers processing power in order to serve pop-up advertisements. Therefore, if you're computer seems to take a long time to do simple tasks or it just seems to be running slow in general, then the odds are pretty good that you have some form of spyware or adware. Many people see their computer running extremely fast when it has nothing on it or when they reinstall windows. The reason is because their machine is no longer infected with spyware.

3)Your settings are being tinkered with

One thing adware often does is change personal settings, in order to display even more ads. Symptoms include changing your homepage to something else, adding websites into your favorites menu, installing new toolbars or adding icons to your desktop. The technology exists now to do this just from someone visiting your website, but quite often, adware companies will install new toolbars and change your homepage once your computer is infected.

Once you suspect you have adware on your machine, it is very important to do something about it before it gets any worse (adware companies will often install more adware on infected machines). To do this, you need to get a spyware or adware removal software. What this does is scan your machine for known adware, and then take measures to delete it. In some cases, your computer may be infected so badly that the only solution is to reinstall windows.

The best protection against adware, of course, is to not download it in the first place. Remember to never click on a link in an email from a sender you are unfamiliar with (adware often infects people who download it from spam emails) and always take caution when downloading .exe files. Don't run a .exe file unless you trust the source or you downloaded it from a trusted software directory. By following these simple guidelines, you can greatly reduce the risk that your computer will get infected with adware.

Better Computer Performance - 9 Free Or Inexpensive Fixes

2007-10-29T22:02:00.000+07:00

Better Computer Performance - 9 Free Or Inexpensive Fixes

Poor computer performance by your Windows-based machine can sneak up on you gradually. You may find its performance deteriorating increasingly until one day you realize you must fix it or buy a new one. Signs of poor performance can include applications running very slowly, programs closing or freezing up suddenly, and a generally slower response time to OS (operating system)-related commands. I have compiled 9 fixes for you here that you can leverage right now to greatly improve your computer's performance.

Fix #1: Download and run MS Service Pack 2:

Every operating system requires patches and upgrades by its maker from time-to-time, with Microsoft XP being no exception. While Service Pack 2 was released in 2002, some people with older systems are still not running it: make sure your computer is. You can download it FREE from Microsoft's Web site.

Fix #2: Run the Disk Cleanup utility:

Your computer likely has a number of unused and unneeded files that take up valuable space on your hard drive and slow performance. Run your FREE, built-in Disk Cleanup utility to automatically remove these files. Find it by going to: Start | Programs | Accessories | System Tools | Disk Cleanup and following the prompts.

Fix #3: Defragment your hard drive:

Over time, your computer will store files in an increasingly inefficient manner on your hard drive, affecting file retrieval times and other performance factors. To fix this, you need to defragment your hard disk drive. To do this for FREE, just go to: Start | Programs | Accessories | System Tools | Disk Defragmenter. First, highlight the drive you want to clean up (e.g., C drive) and choose Analyze. Once complete, choose Defragment. Note that the defragmentation process could take up to an hour or more, so do this during a time when you can step away from your computer.

Fix #4: Run an anti-virus tool:

Computer viruses are malicious programs that drastically affect your computer's performance, either all at once or insidiously over time. You can stop a virus attack by installing and running anti-virus software which performs regular scans, locates the offending viruses and quarantines them.

Fix #5: Clean your registry:

Your computer's registry is a tool that most non-computer specialists never see but which is vitally important to computer operations. Your registry stores settings and options for your hardware, operating system, and other software. Unfortunately, given its fundamental role in the performance of your system, your registry is often the target of attack or infection. To thoroughly and automatically clean your registry, run a regular registry scan using a registry cleaning tool. I recommend RegCure, which recently found 1,626 problems with my registry (ugh!), is cheap and easy to use.

Fix #6: Run anti-spyware software:

Spyware is computer software that installs itself in your computer and performs a number of unwanted functions, including monitoring your computer usage and interfere with your control.

It represents a real threat and has become a significant problem in recent years. Fortunately, fixes are easy to find and include a number of free and inexpensive anti-spyware programs. Try SpyBot Search & Destroy. Get it FREE online.

Fix #7: Increase your computer's memory:

Today's applications require more and more memory (RAM) to run. If your computer is more than two years old or if you selected the minimal memory option upon purchase, you might benefit from adding another 1 GB or more to your computer. Check online or at your local computer dealer for pricing.

Fix #8: Clean your hard drive:

More comprehensive than the Disk Utility tool introduced above, cleaning your hard drive with professional cleaning software is a great way to improve performance. Try CCleaner for FREE by doing an online search.

Fix #9: As a last resort, re-format your hard drive:

If after trying all of the above items and your computer still performs poorly, a last resort is to completely reformat your hard drive. Warning: proceed with caution since this action will erase your entire hard drive, including your operating system (OS)! If you decide to take this route, consult an online tutorial for how-to steps. At minimum, remember two things: be sure to back up all of your files and applications and retain a copy of your OS on CD so that you can re-install it later.

Anti Virus Software - It's NOT 100%

2007-10-27T18:15:00.000+07:00

Anti Virus Software - It's NOT 100%

Ever get a virus? And no, we're not talking about the kind you get from the kid down the street sneezing all over you. We're talking about the kind you get when your computer runs into some nasty vindictive hackers. These are people who have nothing better to do with their time but make other people's lives miserable. If you've ever been attacked by one of these things you know what I mean.

Enter the anti virus software. In short what this software does is detect a virus either on your computer or one that is threatening to slice your PC into little bits and bytes.

The most popular anti virus software companies are McAfee and Norton Anti Virus, the latter actually owned by Symantec. There are other companies and now even some ISPs like AOL are providing anti virus software. But McAfee and Norton are still the kings of the industry.

Before you can understand how anti virus works you have to understand how the virus itself works and how it infects your computer.

Contrary to what people believe there are other ways to get a computer virus other than to open an attachment in an email, though that is the most common way. Email virus infections occur when the user opens up an email with an attachment and downloads the attachment to the hard drive of the PC. What happens from there can vary greatly but in general what happens is the attachment, which is usually an EXE file, when saved, releases some code that performs an action on your computer. This can be anything from getting private information such as passwords and credit card numbers and transmitting it to the sender of the email to simply wiping out your hard drive to the point where it is beyond repair. There are debates as to which is worse.

Another way to get a virus, and this is the scarier one, is to go to a web site who's server has been infected with a virus. This virus can be passed along through the Internet connection and place a dangerous file on your hard drive. Again, the actions taken afterward by the virus can be just about anything.

So what exactly does anti virus software do about this? In simple layman's terms the anti virus software detects the intruding file and tries to do several things in this order.

First it tries to delete the file before it can ever even get saved to your hard drive. If it is successful, it is as if the file never existed and no harm is done.

Second, if it can't delete the file it tries to repair it, if it is a file that is actually yours to begin with and has been modified by the virus itself. If it can repair the file again it is as if nothing happened.

Third, if it can't repair the file then as a last resort it places the file in quarantine so that it can't infect any other files. Yes, viruses can spread. In this case some harm may have been done and you may have to replace the file that has been infected with a new copy. Sometimes this requires reinstalling the software the file came from. Other times the file is simply lost, especially if it is a user created file, though it may be possible to recreate the file depending on what kind of data it contained.

So how does anti virus software detect viruses? To put it simply, your anti virus software has a list of known viruses. It scans every file that you download to your PC and checks it against this list. If it finds a match it warns you of the virus giving you the name of it and then attempts to go through the steps I've outlined above.

So where does this list come from? Well, that's the hard part and the reason that anti virus software can never be 100%. The list comes from known viruses that the software company has either come in contact with itself or viruses sent to them from users who have been attacked. Therein lies the less than 100% effectiveness of anti virus software. There is always a chance that you will be the first one attacked by a new virus. You won't know it until something goes wrong with your computer and then after you report the problem to Norton or McAfee they will have you send them the file you think caused the problem and run tests on it. No, it's not an exact science but it's the best we have.

So since anti virus is not a sure fire prevention the best prevention is not to download attachments when you have no idea who sent them to you, make sure your OS has the latest patches and be very careful about what web sites you go to.

At least you don't have to drink your mother's chicken soup.

UnHack Your Computer

UnHack Your Computer

There's nothing new under the sun, and rootkits are no exception. In the early days of personal computers, in the age of the DOS command-line operating system, there were viruses that hid their presence from the users and anti-virus programs. They did it by intercepting some system calls that were responsible for reading the files, and lied to the system by filling these calls with fake information. You could view an infected file right in front of your eyes and see nothing but legit code! These viruses were called 'stealth' in those days.

When computers evolved, Windows replaced the DOS. Old viruses did not run under the new operating system, and it wasn't easy to develop simple hacks to intercept system calls in Windows. But time has passed, and now there's a new wave of viruses that can work on Windows and hide their presence even more efficiently than the stealth viruses of the old days. These new viruses are called rootkits.

Today, using an antivirus does not guarantee complete safety. A rootkit could install into your system and fool the antivirus system by hiding itself. The problem is that modern antivirus programs try to detect rootkits at the time when they are already active. Antivirus programs use the very functions that are intercepted by the rootkits specifically for the purpose of deceiving antivirus. It's a gun vs. armor race and your PC is the firing range.

Microsoft tried to address the problem by releasing their own Rootkit Revealer. While being a correct concept, this tool fails on too many levels. Microsoft Rootkit Revealer is intended for use by system administrators and software developers. The results of its work are not detections but rather hint that there's something in the system that's hidden. And of course, Rootkit Revealer does not remove rootkits, making its benefits questionable at best for a regular computer user.

Complement your antivirus with a rootkit detection and removal system and liberate your PC from rootkits! UnHackMe with Partizan technology is highly compatible and designed to complement other antivirus solutions instead of conflicting with them.

The Partizan technology is unique to UnHackMe. Microsoft states that there exists no sure way to know of a rootkit's presence from within a running system. Instead of trying to combat rootkits on their own ground, Partizan fools them by booting with the operating system and taking control before any rootkits can load. Being the first to load, UnHackMe can safely watch all stages of the Windows boot process, effectively detecting and terminating any activities attempted by the rootkits.

Once there's no rootkit in the computer's memory, detecting and removing one is a matter of routine. UnHackMe can remove known rootkits by itself or simply block the rootkit from loading into memory and pass control to your regular anti-virus.

Scanning your entire PC for the presence of a rootkit with a regular antivirus can take hours of time depending on the number of files and programs you have. UnHackMe takes scanning speed to another level by taking only a few seconds every time your computer loads.

An overview of spyware and adware - what it is, and how to avoid it

An overview of spyware and adware - what it is, and how to avoid it

Adware and spyware are two different kinds of malicious programs, and each have the ability to make your computer a mess. If you end up using the Internet for anything in your life, or if you rely on your personal computer for anything, it is a very important that you completely understand what these things are and how they work.

The first thing you need to know about protecting yourself from these things is to totally understand what they do. Once you know what spyware and adware is, you'll be able to take measures against it infecting your machine.

What Is Spyware?

According to Microsoft, "spyware" is a malicious type of program with the aim of collecting personal information or changing the configuration of your computer. Spyware is often unethical, in that it is often downloaded without your permission. Usually, you won't know it's even there when it enters your system, and you'll need to have anti-spyware software installed in order to remove it.

What Is Adware?

The difference between spyware and adware is not large, and they are essentially the same kind of thing. With spyware, it is possible that your personal information could be given to another source. In other words, someone is "spying" on you, hence the name spyware. With adware, however, the software is designed primarily to display advertisements on the user's PC.

Is It All Bad?

It is unfortunate, but several people tend to believe that all types of this software are harmful and definitely should be avoided. That's not always the case. Of course, in most cases spyware and adware are harmful and are not the kind of thing you want on your PC, but there are exceptions where you may actually want software like this on your PC.

Remember, to make it spyware it has to be downloaded to your computer without your consent. Spyware can sometimes be downloaded through such things as "driveby" downloads or through other exploits, so that the user never even knows it is on their machine. Any program that is downloaded with the users permission is technically not spyware.

Why would you want to have spyware that tracks your personal information and surfing habits running on your computer? And more importantly, why would you want those advertisements? Well, there may be some exceptional cases it may be useful. For example, you may actually sign up for a service online and when you do you may also agree to receive targeted ads.

Companies like this find it useful to track where you go online (monitoring your surfing habits) and looking at what you do, in order to provide you with ads that are highly targeted to your interests. For example, if you were to search for dog food, the spyware company may give you advertising from dog food companies. So, rather than seeing annoying ads that have no interest to you, you may instead see things that are targeted and useful to what you are searching for.

In most cases, though, spyware is damaging. Many programs such as keyloggers will steal your personal information, and adware is often an inconvenience that most people could do without.

How to detect if you have spyware - symptoms and causes

Spyware and adware are a malicious programs that may have a number of undesirable effects on your computer. Symptoms include changing search results when you do a search on Google, or changing your homepage. Other forms of spyware and adware will even change the configuration of your PC.

The main problem of spyware and adware is that they are very difficult to remove. Often, it will be impossible to manually remove spyware, and you'll need an anti-spyware program to remove it. Here are a few symptoms of a spyware infected machine:

Slowing Your Computer Down

A major annoyance of having spyware and adware on your machine is that they will significantly slow your computer down. Most of all, it can hurt you by being annoying. Pop up ads may happen when your surf the internet, as a result of having adware installed on your machine.

Often, your computer will begin to get slower and slower the longer you have adware on your machine. Moreover, if you don't realize that you have spyware when you first get it, you'll usually end up getting more spyware and this makes it even more difficult to remove.

Why does spyware make your computer slower? Well, your computer is basically made to do more, thus slowing it does. Not only does it need to perform the tasks that you want it to do, but (with spyware installed) it now needs to do a number of other things such as monitoring your surfing behavior or displaying annoying pop-up ads.

Things such as tracking what you're doing, recording information, displaying advertisements and running malicious programs all take up your computers processing power. Thus, your computer will run slower.

In rare cases, spyware can even cause your computer to completely crash.

Relaying Information

Some types of spyware go beyond just displaying advertisements. There are a number of worse types that are also common. Like adware, spyware can track what you're doing and where you're going on the internet.

In some cases, spyware can record the websites you have visited and the keystrokes you have entered. It may take this information and report it back to the company who makes the spyware.

Once your personal information is relayed back to the company or individual running the spyware, your personal information, such as your credit card information, your addresses, paypal account and other sensitive information will be in the hands of the spyware owner. They will then have your username and password for all accounts you have logged into online.

If you have heard about identity theft before, this is where it comes from - malicious spyware programs who record what you do and where you go. Unfortunately, this is alarmingly common and many people do not recognize how serious the problem actually is.

How to remove spyware from your computer

2007-10-27T18:00:00.000+07:00

How to remove spyware from your computer

Once you know you have spyware infecting your PC, it is crucial that you remove it before it does more damage. There are a number of ways to remove spyware infecting your machine. Fortunately, if you have a knowledge of spyware and adware, then it is not that difficult to remove once you have the right tools.

Spyware and adware can be found in the same way as a virus is detected. This is done through a spyware and adware scan, from a piece of software with that scans your hard drive for known traces of spyware and adware. This is the same way as viruses are found. The software will then delete the spyware from your machine once it is detected.

If you suspect you have very large amounts of spyware or adware on your machine, then it may not be so easy to clean your PC. Many spyware programs are very sophisticated and are difficult to delete. In this case, you may need to reformat your entire computer, and reinstall windows. This will involve backing up your entire hard drive and installing windows from scratch as if it was a new computer.

Fortunately, you won't always have to reinstall windows and start from scratch unless your spyware infection is exceptionally bad. There are a number of other things that you can do first.

It's Gotten Bad

It is important to understand that spyware is extremely common, and not just something that happens in rare circumstances. In fact, it is estimates that over 90% of computers connected to the internet are infected with spyware.

You have to consider this a strong risk as you would a virus. Thanks to the sophistication of many spyware programs, you may not even need to download it to get infected. Spyware can get on your computer through "drive by" downloads and other exploits, and chances are you have spyware already on your computer right now.

There are a number of programs around that claim to remove spyware. Some of these programs are spyware programs themselves, and so you need to be careful when downloading software that promises to scan your computer. Make sure you check to see awards, reviews or testimonials for an anti-spyware program before installing it.

In order to remove spyware, you will definitely need an anti-spyware program. Professionally made spyware programs are often very difficult to find and delete, and it is often difficult to get rid of spyware infecting your machine unless you have a program that can recognize it. Good anti-spyware programs will not just scan for spyware, but will also give you instructions for deleting it.

Anti-spyware software can cost you. Also, if you currently have no anti-spyware software on your computer now, then you will need to invest in it, because the odds are overwhelming that your computer will get infected.

What is Data Recovery?

2007-10-27T17:56:00.000+07:00

What is Data Recovery?

Data Recovery is the process of retrieval of inaccessible or corrupt data from digital media that has become damaged or has been corrupted in some way. Data Recovery can be used to recover data from devices as varied as Hard Disk Drives, Memory Cards, Tapes, Mobile Phones, Personal Digital Assistants, Floppy Disks, CDs, DVDs, Data Cartridges, Xboxes and many more items.

If knowledge is power, then after you have finished this article, you will be feeling like Mighty Man when this subject is brought up in casual conversation.

facts Recovery may be wanted for reasons which could embrace issues as diverse as hardware fiasco, (the fasten has been 'chain' up, the hard disk constrain has botched, it could have suffered fire or flood harm, or sensible fiasco, there can be corruptions in firmware, semiconductor fiasco, or accidental fiasco/deletion, a storeroom symbol could have been dropped, a hard disk constrain may have been 'accidentally' formatted). All of these instances will imply the military of a professional data recovery band if the data was of such estimate (be it sentimental or fiscal) that the expense of the military are excluding than the perceived estimate of the data which is no longer accessible.

It is not just businesses who are at expose from data injury. Clients requiring data recovery come from all walks of life, plus governments, large corporate, minor businesses, and the person employed to "Joe open" who, with the introduction and subsequent boom in the use of PC's and digital cameras etc to fastest unusual occasions, feast videos and photos etc may have gone something from sentimental data to risky emails, and personal account facts. Students are regularly grouped under this course too.

There are copious customs that data can be improved from digital media which can disagree soberly; the simplest mode can imply the operation of vital software on the storeroom avenue in quiz. This is accustoms a risky idea, because the recovery data could overwrite the very data that is being improved. More compound commercial software tools are presented which will do this job more professionally. No software fix should be stabled earlier to the earliest media being viewed, enabling the recovering band to work on a 'back-up' of the earliest software. The most professional companies will also take a support view should there be a conundrum with the first view that is being worked on for recovery.

As we continue, we will take a look at how this new information can be implemented in very special ways.

The next conundrum is what happens when the hard disk or storeroom symbol doesn't work. For the minor 'facts Recovery Companies', this is a conundrum, and it is when the more sober facts Recovery Companies get implied. It is accustoms recommended that the most risky work should be sent to a real data recovery specialist, (sound guard out the accreditations - guarantee the specialist has ISO9001-2000 attribute poise type, and is expert to ISO BE EN 14644 to guarantee that their fresh feature is at the mark amount for forward data recovery work, find out how long that band has been trading, and sound guard their testimonials).

Once you have found the band that you are joyful with, if the data storeroom symbol doesn't work, there is a high likelihood that the digital media will imply standby parts. There are specialist organizations which promote standby parts for old and hard to get grasp of disk constrains to facts Recovery Companies enabling them to get the earliest data accessible for long enough to view the data against a committed storeroom symbol, enabling that data to be duplicated again which in transform allows a sound recovery stab to be achieved.

The data recovery job is usually perfect when a tilt of all the improved documents is sent to the client. Once the client approves this sleeve tilting, they are then shipped the data on an appropriate media. This can be a hard disk constrain, floppy disk, CD or DVD. Alternatively, if a sleeve is considered risky, it can be encrypted and then emailed to the client.

It should be renowned that in excessive luggage it may be impossible to recover any data.

The best guidance I can deal the client is this:

"As shortly as you have gone data you should poor off your symbol and propel it to a professional facts Recovery party to optimize your odds of a successful recovery".

Digital Radio: The New American Revolution

Digital Radio: The New American Revolution

Americans are nothing if not selectively fickle. It took almost no persuasion for them to abandon their analog landline technology-based telephones, camera, and record players in favor of digitally based alternatives.

But when it comes to their listening pleasure, Americans have been fighting the digital revolution with as much gusto as they fought the American one. They are however, beginning to come around. Having spotty reception, or none, on long commutes or when in the back country on a recreational outing, or simply because they live in a particularly reception-unfriendly area has finally made many Americans start to take notice of their digital radio options.

The first digital radio alternative is satellite radio. Both Sirius and XM Satellite radio have eliminated the commercials from their digital radio transmissions and are beaming their broadcasts into the automobile receivers of millions of US drivers, no matter where they are located. The glitch is that the service is subscription only, and many older cars do not have the satellite digital radio receivers. And in some large urban areas, the reception is lacking, although Sirius and XM are working on fixes for their problems.

But between them Sirius and XM have still managed to collar only fifteen million of the estimated two hundred and thirty million AM/FM listeners in the US. The two companies have applied to the FCC for permission to discuss a merger, which will cut costs for both. But even a single entity may never move satellite digital radio beyond the niche stage.

The real up-and-comers in the US digital radio field appears to be local radio stations, both because they do not charge their listeners, and because the price of digital radio receivers is beginning to drop rapidly. At the beginning of 2006, a digital radio receiver cost a minimum of $500; now the most expensive are half that. With rebates it is frequently possible to find a digital radio receiver for under $100.

Hybrid digital radio is the result of combining digital power with the regular broadcasting of an AM or FM station. It costs a traditional broadcasting station upwards of $100,000 to make the transition to Hybrid Digital technology, and even then they have to pay royalties to iBiquity, which developed the process. But more than 1300 radio stations have either bought, or plan to buy, the necessary equipment.

Think about it, every shot you take goes through that lens. Really the camera is just a case for the mechanisms inside. You could make a case for reversing the spending, more on the lens and less on the actual camera. Most digital video cameras don't come with the ability to change lenses.

The clarity is much better from glass digital video camera zoom lens.

If you do plan on purchasing a video camera where you can change the digital video camera zoom lens then compare the options of each lens to find the one that you want. Experts recommend that you purchase brand names such as Canon, Pentax or Nikon. Be sure to check if the lens will work for your camera.

Cisco CCENT / CCNA Certification Exam Tutorial: Logging Synchronous And Exec-Timeout Commands

2007-10-17T20:37:00.000+07:00

Cisco CCENT / CCNA Certification Exam Tutorial: Logging Synchronous And Exec-Timeout Commands

Throughout my CCENT and CCNA exam tutorials, you'll notice these two curious commands on the console port:

line con 0

exec-timeout 0 0

logging synchronous

I've been recommending these commands for years to CCNA and CCNP candidates putting their own home labs together, but they can come in handy on the job as well. Let's take these commands one at a time, starting with the logging synchronous command.

When the router wants you to know something, it wants you to know right now. If the router sends a message to the console while you're entering a config, by default the router will interrupt your work to show you that message.

In the following example, I opened a Serial interface, which will always result in at least two messages relating to the physical and logical state of the interface. I started typing a sentence immediately after I opened the interface to show you what happens. I've bolded the sentence I was entering.

R1(config)#int s0

R1(config-if)#no shut

R1(config-if)#^Z

R1#so here i am

4d04h: %SYS-5-CONFIG_I: Configured from console by consoletyp

4d04h: %LINK-3-UPDOWN: Interface Serial0, changed state to uping and

4d04h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to upi've been interrupted quite badly!

4d04h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to down

This may seen trivial, but when you have a long command entry interrupted by a console message, you'll wonder how to prevent that from happening. (After you stop yelling at the router, that is.) By configuring the logging synchronous command on the console port, you're telling the router to hold such messages until it detects no input from the keyboard and no other output from the router, such as a show command's output.

R1(config)#line console 0

R1(config-line)#logging ?

synchronous Synchronized message output

The second command I always enter on the console port of a home lab router or switch is exec-timeout 0 0. This disables the default inactivity timeout of 5 minutes and 0 seconds. If you want to change that timer rather than disabling it, the first number represents the number of minutes in the inactivity timer and the second number is the number of seconds.

R1(config)#line con 0

R1(config-line)#exec-timeout ?

<0-35791> Timeout in minutes

R1(config-line)#exec-timeout 0 ?

<0-2147483> Timeout in seconds

R1(config-line)#exec-timeout 0 0 (disables the inactivity timer)

This command can also be configured on the VTY lines to set or disable the inactivity timer for Telnet and SSH users. Here, we'll set the VTY line inactivity timer to 10 minutes.

R1(config)#line vty 0 4

R1(config-line)#exec-timeout ?

<0-35791> Timeout in minutes

R1(config-line)#exec-timeout 0 ?

<0-2147483> Timeout in seconds

R1(config-line)#exec-timeout 10 ?

<0-2147483> Timeout in seconds

R1(config-line)#exec-timeout 10 0

Some network admins hate these commands, and I personally don't like to disable my router's Telnet and SSH inactivity timers. They're great commands for your present or future home lab, and I also recommend you know them for your CCENT and CCNA exams!

Laptop Battery Memory

2007-10-17T20:36:00.000+07:00

Laptop Battery Memory

When we buy a laptop, it comes to us in a so called "discharged condition." It needs to be charged before usage. To have the maximum capacity, it is advised that the battery is charged at least 2-3 times. The first time you charge the batteries of the laptop, it would indicate that the charge is complete say after 10-15 mins. This, as indicated by several experts is the normal procedure to charge batteries. All you need to do is to remove the batteries and charge them again. You must always remember that the battery should be fully used before it is charged again. If this is not adhered to, then it shortens the life of the battery. The task of discharging the battery is simple. Run the laptop till such time the battery is fully exhausted or till such time you get a message, "Low battery, kindly recharge."

You must however make sure that you use the battery as frequent as possible. Failing to do so, it is wise to store in a dry and cool place. Do not get alarmed to find the battery becoming warm while it is being charged. Remember, a battery which is charge will for sure lose its charge in the long run, if it is not used. Therefore, it is better to charge the battery even after it is stored.

The so called run-time depends on the need for power by the equipment. For example, notebook computers make the use of monitors and the hard drive exhausts the battery, thereby reducing the run time of the battery.

There are several do's and don't which should be adhered to when it comes to battery performance. You should charge or discharge especially for the first three cycles when it is new. You should make sure that the battery and the contact terminals are clean. Be sure that you do not expose the battery to heat and cold. Make sure you use up the battery as the battery may wear of if it is not used for a longer period of time. You can make use of the accessories which come along with the laptop. Recondition the battery after a specific period.

There are however several don't which also should be kept in mind. You must take good care of the battery and not even drop or play around with it. Avoid putting the plug into the wrong socket. Never try and expose the contents of the cell and they may just be harmful. Make sure you do not expose the battery to external problems like water or moisture. Finally throw the used battery away. It cannot be recycled so make sure you know which trash can it needs to be thrown into.

Clean Registry Regularly For Better Speed

Clean Registry Regularly For Better Speed

Clean registry of your Windows based computer at regular intervals. Cleaning registry regularly will keep the registry trim and up to date.

Before we start discussing the need to clean registry for better understanding of the subject and faster computing, let us take a look at what registry is and what is its importance? Registry is a file in which all the hardware and software configurations are stored for the system to function properly. Registry is a typical feature of Windows operating system. That means you will find a registry in each and every computer that runs a Windows OS. More precisely since the Windows 95 version, Microsoft adopted this technique of storing the system configuration through a registry. Earlier, that is before Windows 95, these details were stored in the INI files that used to be stored throughout the hard disc in a scattered way, making the system inefficient and slow.

With the introduction of registry, all the system settings are stored in a single file that helps the system to access these data as and when required within less time. So, registry in a way makes the system run faster. You must be wondering that if registry is helping the system to function smoothly then, why should you clean registry? Before we answer that, let's take a deeper look at the functioning of registry or to be correct, Windows registry.

As we have already mentioned, registry keeps the configuration of the computer and settings of the systems, it also creates a log for every change that you make to your computer. Whenever you install or uninstall any software, add or remove any hardware device, or make any changes to the settings of the system, a log is generated in the registry. The worst part is that the previous log is never automatically deleted, and you need to clean registry to do that. But then what's wrong with the entries? What if we do not clean Windows registry and let all the entries remain as it is?

It is important to clean registry from time to time as to keep the registry up to date. With so many entries that are cluttered in the Windows registry, the system becomes slower and vulnerable to frequent malfunctioning. With registry clean software you can easily clean the Windows registry of all the outdated and unwanted entries. It will always keep your registry up to date and ensure better and faster computing. So, if you want problem free computing experience, do clean your PC registry regularly.

iPhone Availability Tracker

2007-10-13T18:48:00.000+07:00

iPhone Availability Tracker

Apple has launched a small web application that will let customers check up on iPhone availability at its 164 national retail stores. The Apple retail availability tracker allows iPhone seekers to select their state of residence and then will display a list of Apple retail stores with iPhone availability indicators. If there is a green dot next to your local Apple store, then iPhones are in stock. A red dot indicates that iPhone availability is negative. This simple system is a great way to see iPhone availability without trouble. It is an incredibly user-friendly system that can be used by almost anyone.

Unfortunately, however, Apple plans only to update the tracker system on a nightly basis. This, therefore, means that shoppers might want to supplement the information available on the site by placing a call to the local Apple store just before making the trip. This will ensure iPhone availability and save time and hassle.

A separate section of the Apple retail availability tracker website also informs the iPhone shoppers on how to "get the most out of the iPhone," offering lists of free workshops that cover the basics of the iPhone and beyond. In addition, the Cupertino-based company notes that its One to One members will have easy access to private tutorials on everything from how to sync their iPhone with iTunes, to receiving and sending email and surfing the web. Reservations for these One to One tutorials can be made up to 14 days in advance.

The iPhone retail availability tracker is a great tool made by apple. Informing all potential shoppers on where your product is available is a great idea. Shoppers will be more much more willing to buy products if they know that when they go to buy the product, it will be available.

IPhone availability, though, has not been a huge concern. IPhones have been widely available for all buyers. It has not been too difficult for a desiring customer to find a store with iPhone availability. The quantity of phones available has stayed relatively the same since the release of the iPhone. Also, buyers have not been incredibly fast in purchasing iPhones. It seems that many are willing to wait for the price to drop and for the bugs to be worked out. Therefore, Apple doesn't plan on raising the output of iPhones in the very near future. IPhone availability is good, and buyers are happy. Shortages have not been a concern at all.

Overview Of Iphone Accessories

Since the iphone has proven to be a widely popular item on the consumer electronic and computer market, it is no surprise that there are a number of iphone accessories that have debuted on the market. Now, some may be dismissive of the advent of the accessories seeing many of the accessories as unnecessary (this, by the way, is a thoroughly inaccurate notion, albeit one held by many who have gradually become cynical consumers). However, there are a number of vital accessories that provide great value to extending the life of the iphone. Granted, the owners of the iphone seriously need to consider taking proper care of the iphone and its accessories in order to maintain the functionality of the iphone.

Iphone accessories are not going to be worth much to you or your iphone's functioning if they are not properly maintained. Simply owning iphone accessories does guarantee that they will perform perfectly. Consider the following: if you leave your iphone accessories by an open window and it rains, the accessories are going to be destroyed. And guess what? It is a destruction of expansive items that could have clearly been easily been avoided. Granted, the example provided is somewhat extreme. (On second thought, it may have already happened a few times by now) There is a moral, however, to the example provided: if you are going to invest into a series of critical accessories, they must be properly taken care of or the money investment on not only the accessories, but the iphone as well will be utterly wasted.

Of course, there will be those who feel that iphone accessories may be somewhat out of their budget of affordability. In order to purchase those items that are needed, one needs to clearly and effectively decide on what accessories are of vital importance to purchase. In other words, the consumer may be looking at a collective of accessories and deeming the collective as too expensive as opposed to making a decision based on eliminating those accessories that are not important to purchase. In order to drive at this decision, one should separate those items that are helpful in the iphone's operation such as battery chargers vs. those items that are not entirely necessary such as carrying cases. Additionally, a scanning of consumer electronics review sites may provide insight into what products to purchase and which ones to avoid.

Advanced Registry Cleaner Comes With Many Useful Features

Advance registry cleaner tools have some great built in features. The back up, schedule cleaning and other options make the registry cleaner easy to use. With advance registry cleaner software you can keep your registry clean and up to date to ensure better and faster computing.

Registry is an integral part of the Windows based computer. Windows creates and uses the registry file to store all the vital information about the hardware and software configuration and system settings of the computer. Windows registry is a better and improved way to store the vital information as the system can access them in less time and with better accuracy. In earlier versions of Windows that is before the introduction of registry, which came into being from Windows 95, these data about the hardware and software configuration was stored in the INI files. As these INI files were stored all over the hard disc in a scattered way, it took the system more time to access these data.

So, Windows registry undoubtedly benefited the user by making the system efficient and faster. The main problem with the Windows registry is that, it can not keep itself up to date. As all the changes in the hardware and software are logged in the registry file, it becomes cluttered with entries as you keep using your system. The new registry entries keep adding without the deletion of the previous and outdated entries. This makes the registry file cluttered with unwanted and useless entries, resulting in slower functioning of the system and frequent system failures. An advance registry cleaner can eliminate all these problems by cleaning the registry of all the outdated entries.

The advance registry cleaner software is designed to scan the registry and clean it by removing the outdated entries. The registry cleaners tools these days come with smart features like schedule scanning and back up facility. With these complete registry cleaner tools you can schedule the registry scan to take place at regular intervals according to your convenience. It saves your time as it keeps checking and updating the registry at the back ground when you can do other things.

Another plus point of the advance registry cleaner is that you can back up your registry file at any given time. So, in any case if you find out that your PC is not functioning properly after you have cleaned the registry, you can always restore the back up and get the problem fixed up. So without wasting you more time, download advance registry cleaner software and get rid of all pests in your computer.

3D Computer graphics

3D Computer graphics

Powerful computers and computing capability have enabled realism in computer generated imagery. The animated films made today are realistic to a fault. For instance, Shrek 3.0 has been wildly popular because of the life like characters which inhabit the movie.

3D animation basically consists of generating depth in 2D objects by various means. Lighting and shading is a powerful way to provide depth to objects and characters. At first the model of the object is created using a number of polygons. The density of polygons or the number of polygons for a given area defines the smoothness of an object. In applications like 3D video games where real time response is more important than faithful reproduction, the polygon density is obviously less. In applications such as a animated movie, realism of scenes take primary importance. The complexity of the objects requires a high polygon density.

Once the objects have been modeled, they have to be imparted motion or they have to be animated. Finally the animated objects which are essentially 3D in nature have to be converted to 2D. This process is called rendering. More the polygon density, more time it takes to render an object. It is often required to combine video and 3D images. This process is called compositing. Rendering process is one of the most important in generating a 3D image. A small bit of a movie lasting just a few seconds can take days to be rendered. Render farms and piping are phrases associated with 3D animation. Mental Ray is a renderer provided as a part of Softimage and Maya 3D packages. It is also gaining in popularity among other 3D developers. Renderman is a renderer used by Pixar and some large film production companies, for development of feature films.

A number of operations are involved in creating 3D animations. The three most popular software commercially available for 3D modeling , lighting and shading are Maya, 3ds Max and Softimage .Each of the software has its strength and tools to address various requirements of 3D design and development .

Maya was originally developed by Alias which has now merged with Autodesk. The developers of Maya claim its tools have superior capabilities for production of 3D animated movies.

3ds Max is also a Autodesk product, originally from Discreet. Due to its high availability and competitive cost, 3ds Max claims to be the most popular 3D software. It has an excellent game engine and is extensively used for video game development.

Softimage 3D software is a part of Avid. The developers of this software claim mixed pipeline management leading to more efficiency, less time for development and uniquely suited for game development.

3D computer generated imagery has caught the imagination of the public. US based movie moguls are spending hundreds of millions of dollars to create realistic feature films. These in turn are grossing many millions of sales. The 3D computer graphics industry is therefore growing in leaps and bounds. Features like natural hair, skin and human expressions are being refined and polished, to give life like appearance to animated objects.

Microsoft Windows

Microsoft Windows is an operating system for computers. Microsoft is the company and Windows group name for the various versions of operating systems that the company offers. An operating system is the platform for the computer. It makes it possible for the various software programs to function.

An operating system can be described like a power source. You have power coming into your home through the electrical supply. The electricity itself cannot bake a cake. In order to perform a task like baking a cake you will need several appliances that use the electricity. You will need a refrigerator to keep the milk, butter and eggs at a safe temperature until you are ready to use them. You will need a mixer to combine all of the ingredients. You will need an oven to provide the heat to bake the mixture. And it would be nice to have a dishwasher to help with cleanup. This is an overly simplified example, but it helps to demonstrate the difference between an operating system like Windows and software like Office.

An operating system can also be viewed in terms of security. Just like in a home or business, steps are taken to protect the people and property inside. Doors are locked. Alarms are set. Security guards are posted in key locations. Monitoring devices are used. For example, if the business is a bank, the cameras, the alarm panic buttons, the security guards really have nothing to do with the core business of banking. But in a society were safety is a concern, they are necessary for employees and customers to be willing to enter the building.

Another comparison from the business world is the role of a director of operations. This person is in charge of all the stuff that must take place in order for the company to do the work it does. This is the person who makes sure the building is safe and well-maintained. This is the person who makes sure the copiers work, the air-conditioning works, the phone system is up-to-date. This is the person who creates an environment where the function of the company can thrive.

Over the years that Microsoft has been in business, they have frequently launched new versions of the Windows operating system. Each version offers new, enhances features to make productivity and security better. The latest Windows operating system is Windows Vista. New computers that feature Microsoft components will be pre-loaded with Vista. For existing computers, IT professionals and individual owners will likely keep the operating system they already have. The systems will be compatible in most cases. When the company or person is ready to buy a new computer, they will make the change over to Windows Vista.

Windows Vista offers improved Internet experience with the ability to browse multiple pages at the same time from a single window. A Quick Tabs feature will allow you to see thumbnail views of webpages before you open them. Users can set controls to regulate when the computer can be used and what access the different users can have. This is a great way to control a computer used by the entire family.

Movie Social Networking Sites

2007-10-09T18:45:00.000+07:00

Movie Social Networking Sites

With the emergence of social networking sites, there has also been a small influx of a niche in this market - movies. Each one has its pros and cons as they relate to the future and where to go in the future. Below is a detailed look at each one.

IMDB.com: The perfect movie information site. It has virtually every director, actor, writer, movie, tv movie, year released known to man. The site is quoted more times than any other movie site. Often, the information found here is considered law. Its social network side of things is a little blah and lacks a lot to be desired. It has a few login features and some list generation, but other than that it is nothing to get excited about - especially something you and your friends would want to get involved with. The overall outlook of the site is incredibly promising. It has everything that is needed for a movie site, and could easily incorporate a few more interactions with the social side of things.

RottenTomatoes.com: A monster movie review site. It has all the critical reviews compiled for each movie. It does a great job of getting people into or out of the theater with an idea of how good the movie will be. It also provides some info for release dates, actors etc. But, for social networking it lacks a little something. It does have some movie list functions and some message boards to keep people interested in coming back signed in. But, there is no substance or nothing really pushing you to interact.

Flixster.com: A newer true social networking site dedicated to movies. Users can do all sorts of stuff as well as recommend movies, rate movies, review them, and talk with friends. The movie information is there as well. But, it doesn't push you to come back to the site. It has some nice features, but most users frequent the site for a short time never to return. It does have a facebook application, but how much it draws users to the site is unknown. Some call this the myspace of movie social networking - this was the first.

YMDB.com (shompy): Old, outdated, and not frequented much. It has one feature - movie lists. Users can fairly easily create a top movie list, explain why they think it is good, then chat with a few friends who may stumble across their list. It has no movie reviews, no true social interaction, and nothing intuitive. It is a one and done site that never really generated revenue. No one knows how it is able to keep a float. It is possible to get some knowledge about non English films.

Spout.com: This little site has a decent amount of movie information and some cool tools. It finally has some type of movie review feature although all it really is is a blog attached to it. The design is nice and the people seem nice as well. It lacks social interaction and a bug free site. I enjoyed looking for movie via an instant movie search, but it was buggy. It had some good movie list functions and a way to look at hot or not films. In the end though it was a confusing site that most will not go back to many times.

FilmCrave.com: A very young but ambitious social networking site. It lacks a strong movie database (though it looks like it is growing), some social interaction, and a solid heart. What it does have is almost everything else. Strong movie reviews, intuitive movie list creation, enough social networking, and potential. It is less than a month old by the looks of it so it is not known where it will go or grow, but everything looks promising.

YahooMovies.com: A very large part of yahoo is yahoo movies. They have movie reviews, movie lists, recommendations, critics, and number ones. They pretty much have it all. It is not focused or very intuitive. It is a site that can be used once in a while or very often. It has great movie data but as far as social interaction it may be too spread out to get users to enjoy the company of others. It looks like it is mostly used for movie reviews.

As you can see, most sites have good and bad points. It is up to you to decide if any or all of them are worth joining. I find it easier to join all of them then come back to the ones that I feel like I need to come back to. Some day, one of these sites will do all of them combined better than anyone else. Currently, it looks like it could be flixster or filmcrave.

Rewarding Expired Domains

2007-10-09T18:41:00.000+07:00

Rewarding Expired Domains

Reap the rewards from other people's hard work. Often a difficult goal, but this is exactly what you can achieve with expired domains.

Broadly speaking, the life cycle of an expired domain has been:

1 - the domain is registered 2 - a website is built on the domain 3 - the domain is promoted 4 - the domain receives visitors 5 - the domain is not re-registered and the domain expires

Once the domain expires, visitors will still arrive at the domain, only to see that there is no website there any longer. These visitors could be visiting your website.

A lot of effort goes into building a website. And as any web site owner will tell you, getting visitors to your site is a long hard struggle. But if you can register a domain that already receives visitors, this gives you valuable a head start.

Finding one of these visited expired domains can be tricky, and then actually registering them before anyone else manages to can be even harder. There are several websites that specialize in grabbing these domains on your behalf, and some list the domains that are about to expire in the next few days. You can go through this list of domains, and find any with names that seem relevant to your chosen topic.

With this shortened list of domains, you can then conduct research into each domain. The most important thing to check is to see how many backlinks they have - ie how many websites link to each domain. On many search engines, using the phrase "link:" (note the colon) before the full domain URL will return the number of links pointing at a given domain. For example, type in something like link:http://www.domain.com (note that in most cases you shouldn't use any spaces). In general, the more backlinks there are, the more visitors the domain will receive.

There are several other checks that can be carried out on a domain, but finding the number of backlinks is generally the most important.

Once you have found a domain you like, you then need to register it the moment it becomes available - before anyone else does. I would strongly recommend using one of the many websites that offer this service - they have the know-how and beating them to the registration could be a hard task. Also, some of these services have exclusive rights to re-register the domain before anyone else so it may not be possible to grab the domain by yourself.

Your next step should be to check out the different services, and see if any of them have exclusivity on your chosen domain. If none of them do, then chose the services you like the look of and get them all to chase the domain on your behalf. Most of these services will only charge you if they manage to get the domain on your behalf.

You may need to go through this process several times before you successfully register an expired domain that matches your criteria. As you can imagine this may take up a lot of your time.

I can recommend using another service in this field - there are several website out there that can carry out the legwork for you. They list the domains that are about to expire, along with the number of backlinks, and search engine rankings. They are well worth taking a look at.

Blu-Ray: How HD-DVD And Blu-Ray Differ

Blu-Ray: How HD-DVD And Blu-Ray Differ

DVDs continue to be the prominent medium for home theater entertainment. The technology is being refined and improved upon by a number of manufacturers, making its future slightly uncertain though it is definitely clear that it will continue is one format or another. Many of you have probably been hearing about Blu-ray and HD-DVD discs and their path as the next generation of DVDs. The discrepancies between the two are confusing many home theater buyers, so it's important to know just what each of these new technologies has to offer so that you can make an informed decision on what to purchase and when.

Let's start by discussing just what Blu-ray is. Chances are, if you've stepped into any of the leading home theater and electronics stores in the country, you've seen Blu-ray discs advertised in the DVD section. In truth, Blu-ray discs are somewhat like traditional DVDs, except that they have the ability to record, rewrite, and playback high definition (HD) video that is compatible with the growing number of HD televisions finding their way into home theaters every year. Unlike traditional DVDs, Blu-ray discs can hold nearly five times as much data. On a single layer disc, they can hold 25GB of data, and 50GB can be stored on a dual layer disc. By being able to hold so much more, Blu-ray discs are able to easily store the advanced information necessary to provide content in HD format.

HD-DVD offers the same technology, though it isn't able to hold as much information as Blu-ray. Developed by Toshiba and NEC, it is able to hold three times as much data as traditional DVDs. While this may be less than Blu-ray, the data capacity of HD-DVDs still exceeds the amount needed to watch major blockbusters in high-definition. HD-DVD also came out much sooner and was first quoted to be the successor to the standard DVD format. HD-DVD is completely compatible with HD-DVD players, which in turn are compatible with HD televisions. High definition technology is certainly the wave of the future for home entertainment, and HD-DVD was the first disc technology formatted for it.

Both Blu-ray and HD-DVD discs use a new form of laser that improves on what the standard DVD used. While older, standard DVD models used a red laser to transfer content from disc to player to screen, these two technologies use a blue-violet laser instead. The main benefit with using blue-violet lasers is that they have a shorter wavelength than red lasers. This means that they can be focused with a much higher rate of accuracy.

As you can see the differences between these two formats are very few, In short, Blu-ray is able to hold more information than HD-DVD, but HD-DVD has been around for much longer and still holds an adequate amount for any applications currently in the market. Both formats use blue-violet lasers to better read the information.

The biggest question right now is which format will end up on top. Blu-ray has the added advantage of being backed up by some major players in the movie business. Seven of the eight major Hollywood movie studios have released films in Blu-ray format recently, while five of them are releasing films exclusively on Blu-ray. HD-DVD has the backing of several major consumer electronics manufacturers but does have some ground to make up with the production companies. However, with the added experience of being in production longer and having consumers more familiar with the name, it's very possible for them to pull ahead. The race to be the top home entertainment format will continue on and the consumer will simply need to wait to see which one wins. In the meantime, players are available for both formats and some manufacturers have players that satisfy both formats available.

The Incredible, Inevitable Adware Machine

The Incredible, Inevitable Adware Machine

Everyone's heard of computer viruses. You know, those nasty little programs written by even nastier people, programs that love to tear apart your computer's file structure in search of your credit card numbers. However, there's also a category of programs that, although less harmful than viruses, are arguably just as infuriating. The common name for these programs is Adware.

If browsing the internet is one of your favorite past times, then there's a good chance your computer has picked up a few hitch-hikers on its digital journey. Mine sure has. As a college student, browsing the internet for anything to stave homework off for a few more minutes is a common activity, as is searching the sketchiest of forums for textbook solution manuals. It was these activities that made me aware of the importance of a good firewall. If I had kept mine up to date last year, maybe my new computer wouldn't have been dragged into the dirt by adware.

If your computer is suddenly running at the speed of death, then there's a good chance you've picked up some adware. Worse, it could be spyware (stuff that not only throws pop-ups at you but spies on your every move. For the purpose of this article, it's all adware). The stuff I got--a mix of web tracking programs that were feeding advertisers information about my surfing habits and something that would occasionally redirect my browser to random web pages promoting lawn ornaments--was hogging system resources 24/7. I had been planning to reformat my computer anyway, so it wasn't a big deal. But, if I had prevented the stuff from latching on in the first place, life would have been a whole lot easier.

To keep your computer from turning into the Incredible Adware Machine, you only need to do two things. First, get a good firewall. Use the Windows firewall if you have to, it doesn't matter. Throwing a firewall up is a good way of keeping sneaky viruses, worms, and adware on the outside of your hard drive. Second, don't download anything from shady websites, unless you're feeling overly daring. You'll be lucky enough if you don't get a virus, and, if by some miracle you don't get adware too, you've probably used up your luck for the rest of the month.

For those of you with computers already suffering from adware's infernal grip, there is a solution. Big anti-virus companies like Norton have started to incorporate anti-adware and anti-spyware solutions into their products. Next time you go to get the latest version of your preferred anti-virus program, dig a little deeper and see if it comes with anti-adware capabilities. If not, there's a few software solutions dedicated solely to the eradication of adware, and they should do the trick.

Nuts And Bolts Of Data Recovery

You must be aware of the fact that everyday your computer is at risk to almost all the computer disasters available. Whether you are using Mac or a Personal Computer, viruses, hackers, power surges, natural disasters, human errors, hardware failures and many threats can be encountered. For you to keep your data in a safe, you will need to do a back up on your hard drives. However, when hard drive failure takes place, your only solution is data recovery.

Ideally, you need to back up data to keep your files safe and sound. It is also done to avoid the use of complicated process like data recovery. But if you run into steps to prepare your computer from hard drive problems, you might find it hard and experience problems.

Make Sure That You Know The Meaning of Data Recovery: If you are working diligently away on a document or spreadsheet in Microsoft Office and the power goes out, you may still be able to recover the documents you were working on when the lights come back on. This type of data recovery is relatively easy and straightforward. Software manufacturers recognize that power outages are inevitable and unpredictable and most office applications incorporate what is known as auto save features.

At set intervals, the documents you have open are saved to a cached file. They remain in that cached state and should be accessible once your power is restored. Simply opening Microsoft Word or Excel will usually bring these documents back. For instance, when you open Word after a power failure or a software error, you will be presented with a document followed by the word recovered in parentheses. This is the document you were working on at the most recent auto save point. You may still lose a couple minutes worth of work this way, but it sure beats having to go back and retype the entire document.

If the recovered document does not appear automatically, search your hard drive for files ending with tamp. Look for one created close to the time of the power failure or software error and open it. This is most likely the document you had open at the time. If this method of data recovery does not work, you may need to follow the steps listed below.

Try to Call an Expert:

If some programs in your computer do not function well, turn your computer system off. This is a very easy task but you need to do it. This can prevent damages on the disks and avoids data loss. If you will notice an unusual sound, the process is already taking place. The moment you notice that your hard drives are working overtime, you need to turn your computer system off to avoid your computer to self-destruct. If you will not do this simple task, you have your computer system damaged.

There is also a do-it-yourself software for data recovery. However, you have to be careful in choosing which one is for you. Most of the self instructed data recovery software are very complicated and are dangerous by nature. This can ruin the function of your computer instead of treating it. If someone boast about the effectiveness of their data recovery self instruction, be able to know how to handle it properly. Read carefully the instruction and do it well.

Costa Rica Real Estate Makes "Cents"!

It never fails. When I meet someone who has read any of the articles that I've written about Costa Rica, the number one question is: "Why are you always raving about Costa Rica real estate? That's usually followed up by: "What does Costa Rica have that other places don't have?" or "It just seems like it wouldn't be a good idea to invest in real estate in a foreign country." The questions surprise me every time...but not because of what you'd think.

I'm never surprised that the questions are asked but rather at the fact that people still feel the need to ask the question. Though I'm a huge proponent of Costa Rica, I'm not the only person who knows about the great real estate opportunities there. I'm certainly not the only one who has made significant profits from investing in Costa Rica land either. Still, when I come across a person with a question or comment like that above, I just tell them the truth. I say, "I do it because right now, in this first decade of the 21st century, there is no better, safer place to invest money." You know what they say next? "Tell me more!" Here's how I explain it to them...

Costa Rica has a lot of undeveloped land. About one quarter of it is protected to maintain the nation's unique biodiversity but much of the land is earmarked for development purposes. Demand for land is strong, and steadily growing, but it doesn't outweigh the supply YET. Therefore, prices for Costa Rica land lots are low. Inevitably, the person I'm speaking with asks, "How low?"

I usually give them an example. For instance, what comes to mind right now is a community in the southern Pacific of Costa Rica that I've heard about. There, an investor can purchase a half-acre to 1.25 acres of golf course or waterfront land for under $80,000. Add a four bedroom, three and half bathroom house to the mix and they could spend less than $200,000 for both. Property in any other similar location--Hawaii, Jamaica, the Bahamas, Mexico, etc.--would cost two to three times that much. Next, I tell them that property taxes one quarter of one percent of the value of the property, and then they're really interested. (For those who aren't math wizards, that's about $250 for every $100,000!) After that, I give them my top financial reason for investing in Costa Rica real estate: The fact that returns of 100% or more in the first two years of ownership are common!

Once people learn about all of the financial perks of investing in Costa Rica real estate, they understand why I rave about Costa Rica and why investing in a foreign country is a good idea. It makes financial sense and millions of cents. The thing is, that conversation leads to a whole new conversation. It usually begins with, "Can you help me ________," but I don't mind. Makes me feel good to help others get on the path to financial freedom and knowing what it feels like to own a piece of paradise.

Introduction The main concept behind this article is the steps that lead to Designing and developing of Joomla based SEO websites. The first work to be done before going through the steps is to install standard version of Joomla along with some mandatory installation of other essential components (URL changing SEF and sitemap component).

Importance of SEF URL changing component Search Engine Friendly is abbreviated as SEF. At the time of Joomla installation, the URL is: 'index.php?option=com_content&task=view&id=5&Itemid=6'. Standard URL of Joomla does not explain anything related to the contents of the webpage. This feature also called SOS (Search Optimization Stunted) is disliked by most users. SEF URL Changing component plays a huge role in removing this discrepancy. It takes the standard URL and modifies it to become meaningful for a general viewer, e.g. 'purchase-red-bag-here.html'. The drawback that is associated to SEF is that there is a concealed advert in coding from their respective developer. SEF does an acceptable task of transforming Joomla URL's to SEF, still the chances of duplication of many URL is there.

Installing SEF URL converting component SEF URL converter can be installed using interface of Joomla Administration. After installation it is to be checked that 'Search Engine Friendly URL's' is positioned 'Yes' in 'Site->Global Configuration->SEO (tab)'. It is to be ensured that the file 'htaccess.txt' of the root directory during Joomla installation is transformed to .htaccess and then follow the simple instruction for turning 'mod_rewrite' on. It should be followed by going to 'JoomSEF Component and Configuration' for turning it on. After the complete procedure, less confusing URL's can easily be generated.

Sitemap Installation Working out a Sitemap is the next process following SEF installation. The legitimate component of Sitemap is Joomap. Standard 'Joomap' version has no output for a file of XML format of a Search engine. Hence, it is advisable to download a 'Joomap patch', which has similar installing procedure as SEF URL's converting component. There is no configuration required after installing Joomap patch. Now, it is left on us to select and include the menu we desire in Sitemap. Top Menu and Main Menu are generally included. Creation of fresh Items in Menu and selecting the linking components are the task that follows. This leads to getting Joomap and the procedures that are left undergoes automatically.

Importance of Joomap One big advantage that is associated with Joomap is the way it permits to hooking up with Sitemaps of different search engine websites. Admin interface have the URL of Sitemap of search engine website. Now the thing required to do for generating a dynamic sitemap of the search engine website, is to paste the URL in the webmaster interface of the website. At the end of the procedure when the search engine requires downloading the sitemap of your website, it acquires a version that is dynamic in nature. Joomap allows the search engines to get the information of all the pages connected to your website for effective scanning procedure from them.

Windows and Repair

We are living in an Information age and today more and more people use computers to help them reach information or to do some work. Every computer in order to operate uses an operation system and one of the most frequently used operation systems today is called Microsoft Windows. It has many versions but when it comes down to repair there are some fundamental things that people should know to easily help themselves and to know exactly when a help from a specialist is necessary. Now I will tell you about some basic operations you need to learn to perform on a regular basis. The first one is called backup. It is done by simple copy of your important data into one or more locations or you can use more sophisticated methods like partition backups or system backup. I will not give any details because the goal of this article is only to give you the basics to enable anyone who want to begin from there. No matter what happens with your system or application software the backup will ensure the safety of crucial data. When making backup keep in mind that the keeper of it is very important. If you store the backup on your hard drive the chances for it to be damaged are big. They are even bigger when using floppy diskettes or CDs. One good way could be a fast ftp access or on other Internet location that is secured, big enough and fast enough for your needs. The system checking is another opportunity to analyze possible problems with your software or hardware components. Every Windows system has tools designed to help you on that matter. On the market you can find some more advanced software too provided from Symantec or other software corporations. The system registry is another part of your system you should know about. It is made to keep almost every option that software and hardware use to work. Many programs could help you clean it up and tune up your system but you should know that sometimes this could be dangerous because if you damage a critical segment of your registry data the system may crush or some of your software could not work properly. Usually people reinstall the software that causes problems and most of the time this could fix things up but the system registry always needs to be taken seriously no matter what operations you want to perform on it. Many problems could arise when you work with software and that's why Microsoft made some troubleshooting ways to keep their users informed of many issues that people are having. Always start with the help section of the software that you thing is not working properly. Try to reinstall it and then search the web for your problem. This should become a routine when you fight your way through a problem. Information is the most power tool you could ever have. Try to inform yourself on the best possible way before reaching out for solutions which could take much time or even cause more problems. Usually there is a way to repair your installation by using the add/remove programs section of your system tools in the control panel of your system. The software most of the time works together to help you move data and operate on every level you need but this could also contribute for some problems to arise. There are system parts that are shared by many programs and if there is a problem there many programs could ask for repair and give you error messages with code or simple signs. If there is an error you don't understand you can ask professional or search for it on the web. Now I will give you a set of terms and brief discussion on every one of them to help you understand them and use them in the future. The first one is system scan. Scan means analysis and it is in fact a base of rules software uses to analyze possible problems with the system. Hard disk defragmentation is another term. Defragmentation is a process that reduces the fragments of the data that is stored on your hard drive. This is done by reorganizing it and it could automatically be performed for you. Statistics shows that 42% of PC users fails to do that and this usually only affects the system performance and it is not a major problem but you should know that it could speed things up for you and it is not necessary to do it on the day if you need the computer. You could let it do the work during the night when you are sleeping. You could also make it as a schedule task and by doing this you will let the system defrag the disk for example every week on time that is good for you. Keep in mind that your system partition should have a top priory when beginning defragmentation. Today viruses are a major problem when talking about computer systems because they could damage your data and software beyond repair. You should always keep an antivirus program running on the system especially when large amounts of data passes by your system. Everything - even the data accessed by your browser on the web is a potential holder of a malicious code. You don't need to think about protection all the time but keeping an antivirus running and updating it regularly could safe you time and important data. Sometimes when you store important information you may even want to ask professionals to keep you safe because it is impossible for everyone to know even the main principals on how viruses works and how to keep yourself save from them. There are many ways to contact a professional today. This could save you not only time, nerves and money but it could help you design a new way to perform the operations you need and help you take your work to a new plane.

Life of a Camera

Life of a Camera

The best photo's are usually the ones which are the worst for your camera. Going clubbing and tagging your camera along is a fantastic way to recall what happened that night, as chances are, you probably won't remember when you wake up.

The camera will travel with you in the car, getting huge vibrations bouncing on it from the sound speakers. It will then be shoved in a small handbag for safekeeping. When the bouncer asks you for your ID, your camera will play bumper cars with your wallet, sunglasses, make up kit, keys, and all other hard, sharp objects as you toss it about the place trying to find your drivers license.

Once in the Club, it will be yanked out into the unknown. As you extend you hand as far a way from yourself and your group of friends who are huddling around, smiling, your camera will be at the other end, like a box on a crane. It will be vulnerable and open to anyone bumping into it, or knocking their drink, because they didn't see your hand.

During the night it will be shoved in and pulled out of your handbag probably about twenty times, for every memorable moment of the night. Friends who liked each and finally hooked up will be shot, someone falling over or slipping in unknown substance will be shot, people taking shots will be shot, it just never ends.

Taking a camera with on holiday is also ideal. For the entire journey it will make friends with your shoes, toiletry bag, jeans and other items. It will then become very close friends with them, when you turn around a sharp corner and your luggage falls over. On the actual holiday, depending on where you go, it will be exposed to all types of things.

Bumpy safari rides during the day, dust by night or variations of sand from beach to river. It will be exposed to direct rays of light as it sits on the passengers seat, or your baby will chew it while you listen to the tour guide. While you are having a picnic either some strange dog might run off, or ants and other unidentified bugs will crawl all over it. These are all occupational hazards for your camera.

Even day-to-day life of sitting at the bottom of a bag, integrating with grit that has collected there is a life-threatening moment for it. Eventually strange noises will come, as the zoom lens doesn't quite make it out. The springs will grind against dirt from the club, the confetti from the wedding or the sand from the desert.

Bits and pieces will work their way into the mechanism and card errors will show up. Reminders of downloading the images will become more of a warning as both you and the camera sense that your time together has come to an end, unless it has already died from being accidentally dropped into the toilet bowl, or having champagne sloshed all over it from the party.

The chances of a camera having a long life span are slim. The memory card will survive though and with the help of professionals, the images can be revived. Your camera's sacrifice will be worth it as you browse through looking at photo's of your life, yourself, your friends and family and some where your camera will be thinking it was worth it.

Some Specific Reviews on Technology

Although the technology for using a web cam to send live pictures and video over the internet has been around for a long time, video chat technology continues to get better and better. One of the great business tools of the last few years that the internet has brought to the marketplace is video conferencing. All across America, millions of Dish Network subscribers, have ditched the VCR and made the smart move to a free DVR (Digital Video Recorder).

One way to prevent a computer crash and the subsequent need for data recovery is by taking good care of your workstation. One of the most fatal emergencies most people are never really ready to accept is a problem with personal or business computers, as this most often results in vital data loss, and a data recovery system is probably the last thing on anyone's mind when they buy a computer.

In theory, the concept of mobile payments has a strong business case, given the high market penetration rates of mobile devices, such as cellular phones and PDA. After mobile phones hit the market, it wasn't long before phones started to come equipped with games.

So you own the best digital camera? When someone buys a new digital camera for recreational purposes, they rarely look at the type of storage media the camera supports. With the bewildering number of digital cameras on the market, it's increasing difficult to know where to start for your first purchase.

Those of you who like me may be frustrated by the amount of cabling that only seems to increase within the house, each time new computer equipment is purchased, I would recommend checking out a wireless connection with bluetooth as well. If you're toying with the idea of purchasing a Bluetooth headset or set of headphones, you'll need to understand that - as a result of the nature of this type of technology - they aren't as small or light as a headset that isn't wireless. If you're not planning to wear the headset or headphones all day, then you'll need to be sure that they're kept close at hand if a call should happen to come in on your phone.

As technology advanced forward, many of the things we've taken for granted for years are being reborn under the banner of wireless or wireless satellite Internet. Broadband has promised a lot for many years - such as endless streaming content from wireless broadband access at the touch of a button from anywhere in the world. There are a lot of benefits that are offered by the major cell phone carriers today that many people don't take advantage of - simply because they're unaware of them.

Technology and costs have changed drastically in the last few years, and it seems as if today digital cameras nearly out number all the classic film cameras, and to all but the classic photography buffs, digital is the way to go. Underwater digital cameras are small and lightweight, and the quality is comparable to film if you go for the higher resolution shots. Both the film disposable camera and the digital disposable camera are convenient and fun, but if you are looking for professional results or a variety of options, stick with the higher end film or digital cameras.

DISH Network satellite is the second largest provider of satellite TV services in the United States. With more than 250 channels, Dish Network is the fastest-growing digital satellite television provider in the country. Dish Network is the nation's leading digital satellite television service provider, with a customer base exceeding 12 million and a variety of programming that offers something for everyone.

Computer Firewall Security Tips - What You Should Know About Firewall

Computer Firewall Security Tips - What You Should Know About Firewall

The Internet contains so much information and people can search any information from the comfort of their home. You can search and download software, e-books, ordering books, online ticket booking, doing online banking and so much more.

However, Internet also contains threats that will cost you more than buying a new PC. The hackers can hack into your computer and steal your private and confidential information by using malicious software. If the malicious software gets into your computer, it will attempt to send your private information to the hackers without you knowing.

So, how can we prevent the malicious software from sending our private information? The answer is firewall. Firewall can filter your ingoing and outgoing traffic. Therefore, if any malicious software is trying to send your information to the outside world, it will filter it and your information will stay in your computer safely.

Firewall is a very useful tool and it can take the forms of a router, stand-alone server or software. Some people think that if they have an antivirus installed in their system, they no longer need any extra protection. But without firewall, malicious software can easily send the private information to the hackers.

But how can we test that our firewall is working perfectly? Luckily there is a way to test the firewall. The LeakTest software was created to test if the firewall will be able to block outgoing traffic or not. Shockingly, there are big companies firewalls out there that fail this simple test and they claimed that this test does not prove their firewalls cannot block outgoing traffic.

In my personal opinion, this simple test is very useful to determine if you have a good firewall installed in your system. The LeakTest software is a freeware and you can download it for free. Google it and download and remember to read the instruction before performing the test.

Laptop Security .... Why Is It A Must.

2007-10-03T16:35:00.000+07:00

Laptop Security .... Why Is It A Must.

Almost half of the world communities are getting a notebook, I believed it has become an essential need to mankind nowadays.

To have a notebook is an enjoyment but I believed nobody wants their privacy be leaked.

That is why I strongly believed that a notebook security is a Must!

I've been visiting some friends lately and most are asking me the same question, "How to do?"

That's is why I am creating this post to clear any doubts that any users might have in their aim to have not only a fun, lightweight, nicely designed, fast notebook but an unbreakable one too.

Here are the 10 best practices that you can use in order your notebook data is safe.

* Protect Hard Drive with Data Encryption Software If you using Windows Vista, you can use the in built EFS (Encrypting File System) named Bit Locker. It can be found at the Control Panel but unfortunately it only applies to Windows Vista Ultimate and Enterprise editions only. For those whom wanted to use a third party software, there's Steganos. They are currently the leading software maker in security and privacy.

* Track Your Notebook Tracking software are available for you to track keyloggers. What keylogging does is that it detects whatever the users keys in the computer and reports it back to the creator..... kinda like an invasion to your privacy.... no-one would like that!

* Install Virus and Spyware Detection cum Removal Tools An anti-virus and at least spyware removal tool is a need. The "sulks of these robotic mechanism" (in another terms ... pests) can silently be installed in one computer without being noticed. Sophisticated viruses and spywares have been widespread and even the state of the art anti-virus are unable to be captured. But it is essential to protect you from the 99% of all harm and dangers to your notebook.

* Lock It Down How? Use a lock of course. Be it a software or hardware lock, it's essential to those who travels a lot and did not want to loose their prized asset. Cable locks are examples of hardware locks, wherelse Laptop Alarm is an example of the software ones.

* Firewall Necessity The firewall is the first line of defense in every notebook. This should be the primary task. Often users tend to think that anti-virus is the one but however that is not the reality. But these days there are a lot of Internet Security Suites by various companies and you will get the 2 in 1 package minus all the headaches in configuring the anti-virus and firewall separately.

* Patch Up Your OS Windows is a very exposed and vulnerable software. Thus patches are important to block all those "leaked holes" in the system. The same applies to Linux users too.

* Secure Passwords Strong passwords can proof to be a blessing in disguise in protecting your data. But you would want it too difficult as it might backfired on you one day.

* Wi-fi Caution With the convenience of Broadband anywhere at shopping malls, restaurants and fast food outlets ... connecting without caution could have a deadly effect. Remember to disable all "Shared folders" and have your notebook secure before entering such networks. You might not know who might be crawling beside you.

* Disabling Unwanted Services Some services are simply cloaking up the system. Unnecessary for some and even vulnerable left unattended. Thus actions need to be taken in solving this issue. I'll be sharing about this in my next post soon.

* Is Your Notebook Insurance Protected? Some of you might think this maybe not applicable. Well for those who are constantly traveling, this might be a good benefactor as you wouldn't want to loose your prized asset.

Copying DVDs is Easy

Copying DVDs is Easy

The Basics of DVD Copying

The most important aspect of copying DVD's is choosing a program that best suits your needs. There are many available on the market that are easy to use and inexpensive. The first thing to research is a programs ability to be easily understood. The more elaborate a program is designed, the harder it will be to use. Generally, I stick with programs with a one button next step process that is easily understood no matter what level of experience you have with a computer. Secondly, you should have the proper hardware in your computer. Sufficient hardware will make the process of copying much quicker. If your computer is older and lacking adequate memory, you may run into program crashes and 2 hour long copy sessions. Again, do some research and see what other users are saying about the software they use and which hardware they have.Before deciding to copy DVD's, be sure you are the owner of the disc being copied. It is illegal to copy DVD's that you do not own. Once that is established, you may legally copy any disc you own.

Types of DVD Copy Software

After doing some research, you will see many "free" programs offered all over the internet. These programs tend to be easy to use, but some have hidden cost. Be sure to read reviews and be certain they do not contain spy ware or adware. I have personally had good experiences with free copy software, but found they tend to lack some needed options. For instance, you may need to compress a DVD in order for it to fit on a CDR disk. CDR disks are used if you want to copy a DVD to watch on your computer. CDR's are much cheaper in bulk than blank DVD's and can be replaced cheaper if you damage or lose a copied DVD.Some other programs even offer a free trial, which doesn't hurt if you aren't committed to buy.

Why make copies of your DVD's

Making copies ensures your original disks will stay in pristine condition. For example, if you have children who view DVD's in their bebrooms, you know how abused these disk's become. Also, if your traveling you can have copies and not worry about losing them. Basically, you are protecting your initial investment of the DVD you bought.

What Hardware Do I Need?

In order for you to copy DVD's on your computer, you will need a DVD burner. In recent years, most computers now come with a DVD burner. You cannot record DVD's if your drive is only a DVD reader. To determine which kind of drive you have, simply read what is displayed on the cover of your drive. More than likely it will read "DVD R/W". This indicates the drive can read and write a DVD. In other words, it plays and copies DVD's. Another important piece of hardware for this task is memory. The more you have the better. I would suggest a minimum of 1 gigabyte.

It's that time of year again in South Africa, where electricity becomes a gamble. It was this time last year when Cape Town was covered in darkness, at different times, in different stages. This year, hopefully it will not happen, but already in the rural areas it has started.

With continuous power surges, business and individuals are losing money and it's not only the ones that are directly at harm, such as the shops with fridges risk losing produce. Power surges are also causing problems with all companies and individuals that rely on computers. The surge before the electricity blacks out damages the PC, causing the life span of a hard drive to drop.

When the power comes back on, another surge rages through causing further damage. Computer owners are turning to data protection devices to try and control the amount of electricity that is conducted. The device does this by clamping down on the amount of voltage shot through, similar to the workings of a valve system.

The slight catch with these devices is that if the surge exceeds the limit, either the device itself won't be able to handle it, or the voltage will still go through. Businesses that manufacture these devices are now putting on lights so that individuals can see if the device is working or not.

The biggest problem with power surges and computers is the information that gets lost in the process. The surge causes the computer to crash or die completely, causing the system to lose a lot of data. Although more systems are now making it standard to add protection against power surges, it's still a good idea to create backups.

Prevention is usually better then a cure and back-ups are recommended as the best solution. However, with the unpredictability of black outs, generally you can only do this to a certain extent. There will be times when you are right in the middle of something and the electricity will be cut. There are programs that can help with this. They collect the data that hasn't been saved in a cache and keep it until it has been saved.

By doing this, if a power cut happens, once the computer is running again, you can retrieve your data from the cache, without any permanent information being lost. The other option is to invest in a battery operated device. This fits in between the power source and the computer. If the power cuts, there is enough battery power to give you about five to ten minutes, which is more then enough time for you to save what you were doing.

In the worst-case scenario, you will need to take your hard drive to a data recovery specialist, who will be able to find the lost data. It is recommended as soon as you realise there is damage that you don't attempt to recover it yourself, as you might make the situation worse.

Also, unplugging all computers, printers, monitors and everything else after a power cut is also a step in the right direction. When the power comes back on, you at least are able to eliminate one surge from damaging your system.

How to pick right ERP system

How to pick right ERP system

An ERP (Enterprise Resource Planning) system is considered as the only system developed to cover all the basic functions of an organizational work, regardless of the organization's business or charter for integrating all aspects of data and processes related to it. It started as a group of applications or software which focuses on combination of multiple systems into one integrated system through which data can be shared across the company; it thereby reduces redundancy of data entry and processes. It provides almost all the functions of an organization in a single package that is covered by more than one system.

The term ERP signifies the system which is designed to increase the utility for wide resources of enterprise. An ERP eliminates the external interface and replace independent application of an organization as well as provide additional benefits like standardization and lower maintenance which enhances the reporting capabilities in easier or greater manner. ERP is seen as an opportunity to integrate data of systems and refine processes in the interest of gaining efficiencies and to increase employee's growth professionally by the enforcement of fresh knowledge and skills for procedures.

Selection of ERP software is not done all of a sudden. It requires lot of hard and base work to introduce the ERP into a offshore product development system. There are several reasons for uncertainty, foremost being Internet. Because of ERP the scope of computers has been expanded and business has been changed technically. As a result it has increased the demand and expectations which were not seen earlier.

As we all know that business is not a steady process it requires growth and development in this reference ERP package will need more changes. The packaged ERP has proved itself as an excellent in their ability to amend and grow with the business, a flexibility advantage that is often recommended by vendors.

There is no doubt that a packaged ERP solution is better at adapting to changing business requirements, but it is necessary to determine that its flexibility is worthwhile for the cost because it is not necessary that the organization will make fundamental changes in the future. For example, basic business processes such as accounting finance and general ledger will rarely undergo radical changes. But there are several other areas in ERP can be proved as an ultimate solution. ERP is been utilized in many of the areas where the use of computer were not previously. Few areas can be stated as Integrated Financials (General Ledger, cash management, multi-currency, multi-language, fixed assets), Business Intelligence (executive information systems, multi-dimensional modeling), Manufacturing / Importing & Scheduling, Distribution (Inventory management, bonded warehousing, logistics, transportation planning), Customer Service (Sales order processing), Communications (Internet / Intranet).

What are the Differences between Laser Printer and Inkjet Printer?

2007-09-26T15:13:00.000+07:00

What are the Differences between Laser Printer and Inkjet Printer?

The differences between a laser printer and an inkjet printer are really based upon how you plan on using the printer. Unless you are planning to do quite a bit of quality color photo printing both the inkjet printer and the laser printer will work fine. There are, however, a few thoughts to consider as you go about making your decision on what your printing needs really are.

How quickly do you need it?

Pages per minute are one of the leading sales tools of the printer manufacturers. If you need a large print job now a laser printer is likely the printer for you. The laser printer needs a minute to warm up for the first page but once it does get warmed up it can crank out the pages quickly. Then again, think about how quickly you need the print job in a smaller document setting, say several times in a half hour. Do you want to wait that minute three times a half hour, with a client standing at the reception desk? Perhaps the quality can take half a step down in favor of moving that person along.

Spend now or later

Whether it is HP, Cannon, Epson or Samsung printers you can often get an inkjet printer for a song up front. You will, of course, pay as you go in ink costs. If you don't print that much who cares, an inkjet will do. If you print a bunch then possibly a laser is a better long term buy. The benefit here is that you also get better monochrome printing capabilities. Generally, if you're talking monochrome printing you'll find a $0.02 cost per page for a laser printer and $0.15 for an inkjet printer. The difference is that you pay the cost differential upfront with the laser and as you go with the inkjet.

Color

The discussion above was primarily directed at monochrome printing decisions. What if color comes into the equation? Lasers will give nice crisp images but what about their color truthfulness. When it comes to printing pictures inkjets are really the way to go. Laser devotees can chime in all they want but inkjet printers just get the job done better with their individual mixing tanks.

They are also more convenient as you are replacing individual cartridges as you go and not one size fits all. If cyan runs out all you need to do is replace cyan and not the entire cartridge. When it come right down to it, if you want it all buy both and a network card

Tips to Maintaining Your Printer by Yourself

Tips to Maintaining Your Printer by Yourself

It is easy to forget about your printer as you go about your computing needs. It sits there on your right hand side and springs to life when needed. Or at least it is supposed to. If you do not take a minute or two, a couple of time per week, you may find some interesting words coming out of your mouth when streaks or paper jams occur.

Keep it clean

This is easily said and done. The printer heads are the biggie in this area. Printer heads are definitely prone to clogging. If they are not used on a regular basis, or if they are used at a quick clip, they will clog. Every now and again take out the printer cartridges and give a quick clean with a non-linting cloth or moistened Q-tip. If you do use your printer quite a bit think about all those pieces of paper rolling through the printer. It is unlikely that each and every piece of paper will roll through without a shard or tear coming off the paper. These shards will attach themselves to the rollers or other inconvenient printer elements. It is wise to open up the printer every now and again and give it a quick wipe down with a moistened Q-tip.

Turn off and cover

It may seem like many of these tips involve the printer heads, and they do. The printer heads are the area where most preventable maintenance issues occur. Most people, me included, are prone to turning off the computer but not the printer. This leaves the printer heads exposed to the air and possibly drying out. At the ends of the day turn off the printer at the printer. Not from the power cord but at the printer. This will cover the printer heads. Particularly if you are in a dusty region, or if you have a pet, cover you printer. Dust and hair are killers for a printer.

Use the printer

One of the biggest ways to take care of your printer is to use it. Many people really do not use the printer all that much, myself included. This is a digital age and everything tends to stay on the computer. At least twice a week print something that will use all the printers' workings. A colorful website will do but give it a bit of a workout and most of the other maintenance issues will never arise.

How do Laser Printers Work?

2007-09-26T15:10:00.001+07:00

How do Laser Printers Work?

It is one of those things that most of us really don't think about. How does a laser printer work? Well, you click "print" and it works, right? For most of us that is all we need to know or would care to know. But, in reality, it is something you should an understanding of if you are going to be buying a laser printer for the office network or shelling out a decent amount of cash.

Chemistry isn't that bad

Most people have horror stories about chemistry class, me included. But when it comes to figuring out how a laser printer and chemistry work together it is not all that bad. Whether it is a HP, Epson, Cannon or Dell laser printer it works the same way, positive charges and negative charges. The old saying actually applies, opposites attract.

Getting charged

Within the laser printer there is a drum that slowly turns. As it turns it is given a charge by a wire (charge corona wire) or, in some cases, another roller. After the drum is charged the printer shoots a laser at the surface of the drum discharging the drum in certain places. These places end up looking like letters and numbers on the drum.

To get these discharged letters and number shapes off the drum and onto a piece of paper the laser printer covers the discharged shapes with charged toner. It then hooks them up with an oppositely charged piece of paper. As makes sense the toner is attracted to the paper and there it is, toner on paper. If you have ever changed a toner cartridge you can attest that the stuff loves to attach itself to just about anything. The process so far just makes the toner attach itself in an ordered fashion or letter and numbers.

Getting toned

The process is just about complete at the most basic level. What needs to happen to finish off the process is for the toner to be fused into the paper permanently. To accomplish this the laser printer rolls the paper by a heat roller to melt the toner into the fibers of the paper. As the laser printer does this it real eases the charge with yet another roller.

Ultimately, when the process is in synch there is no muss and no mess. But everything needs to be timed just right. In the end, there is a warm static free piece of paper with all the words fit and unfit to print.

iPod Downloads - Free or Not Free

2007-09-24T22:25:00.000+07:00

iPod Downloads - Free or Not Free

Just about every where you look there's an ad for freeiPoddownloads. When you get to there they all want money. Is it or Not?

Why people or online business's advertise "freeiPoddownloads" is beyond me. If some one say's free then it should be right? If you see an ad, link, classified or even an article and the title say's you can get free-downloads, then wouldn't you assume that after clicking that link you would land on a page or website that allows you to download any thing you want, right?

Well how come when you do, it always seems to be the same old story. They all want money to access to unlimited iPoddownloads. Now that's not free is it?

It just simply isn't true. As far as most people are concerned that's false advertising, but the twist is when you pay to join one of these iPod-Downloads, then you can have access to all the free-movies, games, music you want. So the right thing to do and I think and the majority of most people would agree is if someone advertises the word free and expect you to buy some thing then the word buy should be included some how or say something along the lines of "FreeAfterYouBuy" right?

The Danger of Free iPod Downloads

If you do a search on Google or Yahoo for "FreeiPodDownloads" you would get a ton of results. The one thing you have to look out for when joining or getting free access to iPod downloads is the viruses and spyware that come with them.That's right when you download media file's from unprotected resources or file sharing networks you are vulnerable to all these danger's.

So the best way to avoid this problem would be to find a review that you feel most comfortable with and the reason being is because they allow you see what works the price and there best recommendation. Another good thing to know is, just about all review sites post safe, legal iPod downloads that you can trust and not have to worry about getting some strange virus that will do all kinds of damage to your pc.

The Best Way To Get iPod Downloads

Find a site that you feel comfortable with and pay the $30.00 or what ever it is their asking for instead of trying to get away with getting something for nothing. Because there is usually some stipulations (and in this case risky ones) that come with something for nothing.

Consider this, there are some excellent iPoddownload ebsites out there that will give you way more for less other then getting free iPod downloads for nothing and sometimes less is better then nothing because nothing can be allot more trouble then what it's worth.

The Need For Quality IT Support Staff

2007-09-24T22:24:00.000+07:00

The Need For Quality IT Support Staff

Any company engaged in providing IT support will no doubt exercise great care in who they hire on their roster as the importance of a good; if not outstanding IT support staff cannot be emphasized enough. It means having a good IT supervisor who can coordinate computer programming as well as perform system analysis. He/she should also coordinate computer operations such as data exchange methods, and also submission as well as distribution. The IT support supervisor shall also need to be able to format specifications as well as do the coding procedures. There may be more than one supervisor with others being involved with other aspects of IT support such as overseeing systems programming for workstations as well as taking responsibility for database administration and being there to answer specific issues related to individual edits.

At a lower level, the IT support staff would consist of persons that provide administrative support to the client and maybe even assists in website maintenance. There should also be personnel available that will manage the client's local area network as well as other personal computers and also should be able to manage Internet servers and also their applications. Other responsibilities should include installing as well as upgrading personal computer hardware as well as software.

Some of the IT support staff may be hired to provide computer programming support and are responsible for writing code to process as well as edit incoming data. In reality, the responsibilities of the IT support staff would also encompass day-to-day support for an information system that could even involve handling the client's multiple sites. The support staff should have the requisite knowledge as well as experience to handle PC as well as MAC hardware repairs, Server OS, Exchange as well as are able to maintain network switches as well as infrastructure. It is also necessary for the IT support staff to have good and even excellent communication skills as well as be good with people skills.

It is also a requirement for IT support staff to have at least two years of college background in the relevant subjects, A+ Certification as well as is Microsoft Certified, with hands-on experience in relevant hardware and software platforms. An individual with MCSE or CCNA would obviously be well suited for the job of IT support staff.

IT support spans a wide array of services for which a company that provides such services would need to look for specialists to handle the various functions required. There is an administrative side that handles normal client needs such as email, internet, computing services, mailing lists, and user groups. The support staff should also be conversant with various administrative systems in order to discharge their duties satisfactorily. In addition, they may also be called upon to provide training and provide resources and also handle telecommunications as well as other computing services.

With all these different areas of functionality to be addressed, the IT support staff needs to actively be the customer's backup against all manner of breakdowns and disruptions which should be dealt with and put right at the earliest possible time.

Computer Forensics Files: The Case of the Little Dame That Wouldn't

Computer Forensics Files: The Case of the Little Dame That Wouldn't Real CSI Cases from Burgess Forensics #14

The stories are true; the names and places have been changed to protect the potentially guilty.

A dame, a rich guy, and an email account: what more do you need for a story?

I was in my office one fine spring day in Marin studying the benefits of Eastern philosophy, engaged in my special snoring meditation, when the buzzing of the telephone dragged me back to the present. It was Sam & Dave - not the Soul Men, but the lawyers in the Valley. They had a situation. A computer expert was heading over to their offices to make a copy of their client's computer - the dame's laptop - to try to prove that she sent endearing emails to a scorned male - the rich guy...Mr. Silicon Valley.

See, rich guy had not been so rich until some computer hardware of his design had been snapped up by a big player in the computer world for a hefty sum. Newly rich Mr. Silicon decided to try his hand at picture books - picture books of natural looking young ladies in their native birthday attire. The hook was that they would be all natural - no silicone for Mr. Silicon.

One day, Mr. S was driving through the Rockies when he espied a liberated young lady. Liberated in the sense that she was 17, but living on her own. S offered to liberate her from a deadend waitress job if she would come live in his Valley mansion. It would all be very Platonic - they'd each have their own end of the mansion - and she would work with the picture book office staff.

But as our young lady reached adulthood, Mr. S became enamored enough to make our lovely waif a bit uncomfortable. She thought he was acting like a creep. She wanted out - out of the office and out of the mansion. The word "harassment" strikes fear into the heart of many an employer, and Sam & Dave were looking for a settlement to enrich all involved. But Mr. S was not to give up so easily. He maintained that the lovely Miss had been sending him endearing loveletters from her America OnLine account. Sure enough, her account had sent those letters - but had she been the one to send them? AOL has a setting that allows a user to sign in automatically - that is, to sign in without having to type in a password. This setting is nearly always a mistake, unless no one else is ever near your computer. I always recommend to my clients that they take the extra 5 seconds out of their busy schedules to type an actual password. You might have guessed that her AOL was set to automatically login.

But the letters had been sent after she had already left the office. That meant that if she had sent them, she must have drafted them on her laptop from home. A deal was made. Mr. S hired a computer expert to do some digital discovery. He'd make an identical copy of the hard disk from her laptop, while sitting in Sam & Dave's conference room. This is where I entered the picture. S & D wanted me to make sure that the hired thugs ... er, experts ... would not pull any funny stuff. I went to observe on the day of the copying.

Just a short half hour or so after their scheduled arrival, the other experts arrived. They were decked out in full company regalia. Their bright jackets, hats, and business cards announced their offices in New York, Tokyo, London, Hong Kong, and Los Angeles. These guys were apparently internationally jetting big shots. As it turned out, only one was the bigshot - the other guy was the gofer. Bigshot sat in a chair and bragged about his exploits while Gofer unloaded their equipment. A large, high-powered desktop computer, with external drives hooked up through an Adaptec SCSI host adapter appeared on the tabletop. A briefcase full of secret computer forensic software was opened to reveal its treasures. The golden floppy disk was removed from the briefcase. Bigshot examined the laptop, and announced, "We can't do this copy - there's no floppy drive."

I was a little dumbfounded. Surely these guys had all of the computer forensic equipment known to mankind. "I have EnCase and ByteBack," he said, "but I need to boot from a floppy drive to make a copy." This was at least half accurate. Whenever a drive is operated in a Windows environment, Windows writes bits and pieces of data to the drive. Under such circumstances, the data is changed and is not a true identical, "bit-for-bit" copy. It's not a forensic image. But when the system is booted from a DOS diskette, nothing gets written to the hard disks. This is what the fellow was looking to do.

I suggested he remove the hard disk from the laptop, and hook it up through a write-blocker to his desktop computer. "What's a write-blocker?" he asked. "Gofer, do we have any write blockers?" Gofer's look of befuddlement answered for him. I explained to Bigshot International that a write blocker is a device that can be hooked up between the hard disk and the cable it is attached to, or between an external enclosure holding the hard disk and the USB cable leading to the computer. The MyKey NoWrite FPU is one of my favorites. The Tableau works well. The Disk Jockey Forensic wasn't around then. The DriveDock & others would have been fine. But he didn't have any by anyone.

Still, removing the hard disk, attaching it to his system and booting the system from his floppy diskette should have been fine. I suggested as much. "How do you take out the hard disk?" he asked. Apparently laptops are different in London and Hong Kong and those other places he had offices.

I asked S & D's secretary for a little Phillips screwdriver, and removed the hard disk for Our Man. "It doesn't hook up to my IDE cable," he said. You see, laptop IDE hard disks and desktop IDE hard disks are different sizes. Most in laptops are 2.5" and most in desktops are 3.5" and never the twain shall meet - at least, not on the same cable. The 40-pin connector on the laptop is, unsurprisingly, smaller in size. "How about an adapter?" I said. "Have you a 2.5" to 3.5" adapter?"

"Have we got one, Gofer?" Befuddlement answered wordlessly again. I suggested a quick run to the local computer store. I even volunteered to go, for the Mensa-level technical skill was getting to me a little at that point.

Twenty minutes later, we had an adapter from a local Mom & Pop computer shop. Some adapters for laptop drives hook up the opposite way from what is intuitive. Once I warned against hooking the laptop drive up backwards, Bigshot got everything set up right, the computer booted, and a good copy seemed like it was only minutes away. That is, until I heard, "My target disk drive isn't big enough." Well, I didn't want him to have to go all the way to Tokyo or New York for another. I suggested hooking up additional drives from his special briefcase to the SCSI bus, then changing the image size. Many computer forensic programs allow one to acquire a large drive as several or many contiguous images of a smaller size. By changing his configuration, Mr. B could make many successive CD-sized images of about 650 MB each, instead of one giant one that wouldn't fit in the available space in any one of his hard drives.

With the copy proceeding apace, I asked S&D what I should do next. We saw the estimated time of completion was about five hours away! I wondered if sitting waiting for electrons to move was the best use of my time and their money, and they seemed to think it was not. I explained what to look out for - any cables being unplugged, any keyboards being typed on, any utterances of "oops" or "oh no!" from the Dynamic Duo making the copies. The job should be mostly babysitting until the copy was completed. I headed back to the airport, and to my offices at Burgess Forensics to finish my interrupted meditation.

How did it all turn out? There were no loving emails drafted on the laptop. The computer she had used at the office was being used to send bogus emails from her auto logon AOL account. Mr. S was ready to settle... after just one more meeting.

As part of the settlement, Mr. S & our lovely Miss had one last lunch together. They met at an outdoor café. It might have been romantic, but Miss sat well out of reach, her lawyer sat just out of earshot a couple of tables to the West. The attorney for S sat just out of earshot a couple of tables to the North. Everybody ate lunch. S paid the bill - three bills, actually - one for lunches, one for the lawyers, and one settlement for the lovely lady. She then walked away and never looked back.

While I never met the lady, I was alerted to look for her on a fashion show. There she was, on the TV, looking like the waif models are apparently supposed to resemble. I couldn't tell if she looked any richer, but I hoped she would spend some of the settlement on a few more lunches - she could have filled out a little and looked a bit more...natural. But that's outside my area of expertise. A nutritionist I'm not - I do computers.

This is just one of the many "CSI (Computer Scene Investigation) - Computer Forensics Files: Real Cases from Burgess Forensics" cases in the file. Stay tuned for more stories of deceit uncovered by science.

Conference Calls Are Good For You

2007-09-24T22:21:00.000+07:00

Conference Calls Are Good For You

You need to call a business briefing, but some of your employees are traveling to pitch the company at a trades show three states away. You'd like to present a sales pitch to a potential client across the country, but they want to hear your group's ideas now, not whenever you can send someone out to them. You want to ask a couple of co-workers a few questions about your latest project, but you're all too busy to leave your desks and set up a "formal" meeting.

Conference calls have been the means to bridge the gap between co-workers, customers, and clients for decades. Conference calls allow three or more parties to touch base or conduct business from one part of the building to another or from across the world.

Conference calls are still frequently used to speak with co-workers inside the same building or even to hold meetings when co-workers are on a business trip, but most conference calls, particularly sales pitches to clients, are now Web conference calls or a combination of traditional conference calls and Web conference calls. The video and data-sending ability of Web conference calls makes business more productive as it allows potential clients to see the charts and outlines of a sales pitch.

Conference calls are also often used for companies to offer a means of communication to their stock holders or for local politicians to offer an open-question line to his or her constituents. The stockholders or the public, people who might not usually get a chance to meet corporation representatives or politicians in person, are given a phone number to access an "open meeting" held over conference calls, allowing them to call from the comfort of their own homes.

Conference calls have also long been used for social network connection, like with "party lines." For a fee, callers can use the conference calls service to chat with three or more new people at once, looking for new friends or dates. These types of conference calls were more popular in the 1980s and early 1990s, before the advent of Internet chat rooms and text messaging party lines, but they still exist today.

You can take this social network conference calls idea to organize any number of large functions, like family reunions or weddings, and speak with two or more family members or function services at once! Be as efficient and organized as a typical corporation and take advantage of conference calls!

Most phone companies have three-way calling or conference call options included with their service, although there is an extra charge for all conference calls. If you operate a business that frequently makes conference calls, you may want to find a better deal on conference calls and you may want to work with a conference call company that can set up your business for the fastest, most reliable conference calls and Web conference calls.

There are a number of businesses that offer low prices to facilitate conference calls, whether through the phone or the Web. Visit conferencecall.com, corporateconferencecalls.com, or conferencecalls.com to start shopping around for the best facilitator of conference calls for your business or social event!

Hard Disk Data Recovery Still An Important Asset

Hard Disk Data Recovery Still An Important Asset

Hard disks have evolved along the years to be a lot more reliable than their ancestors, but no matter how good they got to be, they are still open to damage and errors that could cause loss of data. If this happens, hard disk data recovery is the solution and a big problem solver if the information on the hard drive is important and not backed up.

A hard disk can crash because of a range of different reasons but the most encountered is an unstable power supply. A hard disk is quite open to attacks from sudden power surges or power outages. Such power problems can cause both physical damage and logical errors. Logical damages are possibly easy to fix with a HDD scan and fixing the disk file system.

In most cases, you can observe some signs or symptoms that the unit is about to crash. An imminent crash will cause frequent disk error messages. If the disk will not be shown during the startup of the operating system or the information provided is incorrect when the disk is analyzed are almost sure signs of hard disk damage. If you can hear your HDD make weird sounds, clicking or whirring, the problem is mechanical and you will need professional hard disk data recovery assistance.

Some regular clues that may suggest hard disk damage are:

* When files are accessed or the system is powered up you might head ticking, grinding or clunking noises * Problems with the operating system booting process * Problems reading files that exist on the hard drive

To have your data safe, in case you notice such signs, make sure you back up the drive or the most important information at least. This way you will have an easy solution if the worst happens.

There are software applications that you can use to recover hard disk data and correct logical errors but they are quite dangerous in the hands of unexperienced users. If the information present on the damaged hard drive is of an elevated importance you might want to use the services of hard disk data recovery company.

Zombie Computers Roam The Internet

Zombie Computers Roam The Internet

Spyware and viruses are so common that you would be hard pressed to find anyone that isn't aware of them. Under the umbrella term Malware, these little programs have been causing trouble for computer users for many years, and they seem to get more powerful everyday. A new incarnation of malware is becoming very common as of late, and it involves using a virus or trojan horse to place a computer under the remote control of a hacker. The controlled computer is referred to as a zombie and it is used to commit various dastardly deeds without the knowledge of the computer owner.

Zombie computers are almost always attached to the Internet via a broadband connection such as DSL or Satellite Internet. This is important as spammers have found that by using zombie computers to send out their junk mail they can easily avoid detection. As of 2005 it was estimated that up to 80% of all spam was sent via zombie computers, and that number is on the rise.

The increase can be attributed to smarter hackers and better technology, but the real driving causes behind the increased zombie trend are better spam filters and anti-spam laws. According to Tom Spring at PC World Magazine, "spammers are hiring virus writers and hackers to help them create armies of zombie PCs to send spam." This union of hackers and spammers has been beneficial to both parties in opening new revenue steams that are extremely difficult to shut down.

Gregg Mastoras, a senior security analyst at the security firm Sophos says, "A new underground economy is evolving." This new economy is for the most part illegal and to date impossible to stop completely.

As of late the Chinese hackers have thrown their hat into the game and have taken the zombie computer business to the next level. Senior Pentagon Advisor Paul Strassmann recently said, "As of September 14th 2007 there were exactly 735,598 computers in the United States infested with Chinese zombies".

Large groups of zombie computers can be used to form a "botnet" or network of slave computers. This network can be used to send out millions of spam mails in a short period of time. Slave networks are also used to commit a DoS attack. DoS attacks, or Denial of Service, target a particular website and overwhelm the server with information requests until the server can no longer handle the load. These attacks or in no way secretive, and once discovered are easily shut down. There will be a period of time however when site traffic will be disrupted by the DoS attack. Larger more sophisticated networks such as those used by governments or large firms have defensive measures in place to prevent damage from a DoS attack.

Try One of These Four Tips to Watch TV On The Computer

Imagine viewing with your PC the thousands of videos, TV shows and movies that the Internet has to offer. If you have a laptop, then your TV viewing can be done on the go wherever you have access to the Internet.

Things are even more interesting if your Internet connection is wireless. These are just a few of the benefits of watching TV on the computer and this article will give you four tips on how to do this.

1) There is an enormous quantity of classic films, old movies and TV shows as well as documentaries available for you to view in the public domain. When the copyrights of content expire, they are placed in the public domain and can be viewed or even sold by anyone.

Try looking for this material on a search engine using phrases containing 'public domain' plus 'film' or 'video', etc. With just a bit of persistence, some real gems can be uncovered.

2) If you wish to view the shows that your television receives on your monitor, then you may want to purchase and install a TV tuner card in your PC. Many tuner cards will also record television programs into your computer's hard drive for later viewing.

No Internet connection is necessary here since the TV tuner inputs the same signals that your TV set does. If you are looking for quality, you can expect to pay anywhere from $100 to $200.

3) Want to know a guaranteed method of getting DVD quality movies to play on your computer? Just put a DVD into your CD-ROM drive! Before you attempt this, you have to download the right media player with this functionality.

You can download it free at Realplayer.com. Find the yellow 'Get it free' button, click on it and follow instructions. When you're finished with the download and installation, insert a DVD, start the player, open the 'play' menu and click 'Play CD or DVD'.

4) One of the more popular ways to watch TV on the computer involves the use of software that allows you to watch satellite TV over the Internet. Since the TV shows come over the Internet, no satellite dishes or other hardware is required. All that you need is a PC and an Internet connection.

With this software, you will typically have access to more than 3000 channels all over the world . The software prices are between $40 to $100. This is a one time purchase that will set you up for life with no other recurring fees or payments.

Hopefully this article has given you an idea of what's available to you through your PC and its connection to the Internet. The good news is that there is no end in sight to the explosion of Internet TV and video.

Finding The Best Ergonomic Chair For You

2007-09-23T23:46:00.000+07:00

Finding The Best Ergonomic Chair For You

It isn't always easy to find a cheap ergonomic chair or a low cost ergonomic office chair. Incorrect ergonomics can cause back pain, neck pain, shoulder pain, headaches, and other medical issues. Whenever people shop for chairs and desks for the home or office, they're not usually looking for something that is good for their bodies, but more about what looks good or is low cost, cheap or what's on sale.

No matter what the task, an ergonomic chair or ergonomic office chair will pay for itself fast due to less pain and increased productivity. The terms computer ergonomics and office ergonomics are often used to mean the same thing; they are usually referring to body-adapted ergonomic chairs, office chairs, stools, desks, keyboards, mice, etc. Try out several chairs at furniture, office supply and back-care stores before you pick the best ergonomic chair for you.

There are some extra large ergonomic chairs that are great for security guards as the size of this chair allows for equipment to be worn on the belt and not to become hooked on the arms of the chair. Fabric selection is important with the ergonomic industrial chair as cleaning may be an issue. For ergonomic industrial chairs and seating the caster selection is particularly important for industrial or manufacturing areas; you'll want a hard floor caster designed for concert floors.

Ergonomic intensive use chairs or seating, also known as 24/7 seating, is for dispatch room security monitoring areas, control rooms, and 911 emergency dispatch offices. Tilt options on the industrial chair mechanisms as well as cylinder height must be considered depending on the job to be handled. Ergonomic intensive use chairs are very durable and especially need to be ergonomic in design, because workers are typically sitting for a lot of hours.

Adequate lumbar support in an ergonomic chair is the most crucial element of a backrest. Look for chairs that provide mid-back and upper-back support as well. The seat should always extend at least one inch from either side of the hips for optimum comfort because insufficient hip room can make you sit too far forward and not get enough thigh support.

Look for an ergonomic chair on wheels that swivels to avoid excess stretching and twisting of your spine and a five-point base won't tip over when you recline. The tilt mechanism maintains support as you move and recline; it's best to have your back slightly reclined while seated at your desk.

The seat pan is the component of the chair that supports the majority of the user's weight. Three or four fingers should fit between the seat pan's front edge and the back of the knees. Tilt adjustments are preferred to allow for a forward working or reclined posture.

Other ergonomic products you can buy include: document holders, ergonomic workstations, telephone mounts, ergonomic keyboards and mouse devices, footrests and speaker stands. It's important to remember that you probably spend a lot of hours on your computer and it's really a long term investment in your health. Hopefully these ergonomic facts and tips about features and types of ergonomic chairs will help you when shopping for or buying an ergonomic chair online or at your local office supply store or office furniture store.

The Truth About SEO And Meta Tags

2007-09-23T23:45:00.000+07:00

The Truth About SEO And Meta Tags

In earlier days, when the Internet was still pretty new meta tags were everything. They were vital in helping search engines determine what the site was all about and how to rank the site in their search results. When the databases were smaller and more manageable, this meta tag provided a quick and easy way to figure out which keywords were important on a site. At that time, meta tags were king. Many SEO services could get web sites placed high because of the presence of meta tags.

As the Internet grew larger beyond all expectations, there was fierce competition in trying to get into the search engine's top ranking. SEO services who could not get their sites ranked through fair means resorted to unfair means. In an effort to bring traffic to their site they abused the system by incorporating useless and completely irrelevant keywords into their meta tags.

With the result that today, Google and most other major search engines pay little or no attention to meta tags. What is given more importance is the content within the pages of the site. A few engines still take notice the words within the meta tags, but they are used more as minor supplements to the actual content and title tag of the web page.

So, should you or shouldn't you use meta keyword tags anymore? It certainly couldn't hurt to use it. Search engines use many different factors to determine site rankings, so it makes good sense to use meta tags along with any other acceptable and legitimate technique that is available. At best, it increases your chances of getting a higher ranking and there's no downside to it unless you rampantly stuff your page with irrelevant keywords.

Website Performance And Load Testing

2007-09-23T23:44:00.000+07:00

Website Performance And Load Testing

Your company is rolling out its new web application. This web application is well designed and attractive. It has been well tested by your quality assurance group. You have spent a lot of money marketing your new website. The website now goes live. Very soon you realize that your new web application is unable to scale to your typical production load and the response times and performance reach completely unacceptable levels. Your web logs indicate that most of your website visitors simply leave the new website before buying anything since its response times are very poor. You start to panic, and one of your friends tells you that the reason your application does not perform adequately is that you do not have ample hardware. Hearing this, you decide to add more server hardware. While this has a small effect on the website response time, it is still woefully inadequate. You soon realize that problem does not really lie with the hardware but rather with the web application itself. It appears that your web application was not well optimized for the typical peak loads. It becomes increasingly evident that most of your marketing dollars were wasted.

Enter the world of performance and load testing. In order to ensure that your application scales as the load increases, it is necessary to perform tests where your application is tested against a simulated load that closely resembles the actual load that it will be subjected to when it is exposed to the outside world.

It is important to distinguish between functional or regression testing and load or performance testing. Functional and regression testing is used to automate a large number of scenarios to ensure that your website works as intended. Load testing on the other hand gauges how well your website performs when it is subjected to a large load, such as a large number of simultaneous users.

Load and performance testing require the use of automated testing tools. It is impractical if not ridiculous to try to simulate a load of 200 concurrent users by having a group of 200 folks sit on 200 machines and try to perform operations at the same time. Before you can begin any kind of load and performance testing you will need to identify the test scenarios you need to automate. A load testing tool will typically record web requests and responses based on user interactions with a website. As you perform various operations on your website or application, the tool records all the web transactions that take place. When you finish recording, it generates an automated script. Alternatively you could use the tool to manually create the script. Typically testers will perform a combination of the two. They will use the recording mechanism to generate the skeletal foundations of their scripts and then manually modify the scripts to take into account specialized scenarios. The load testing tool should also allow the tester to simulate constrained bandwidth situations. This means for example that it would accurately model users who would use the application on a slow modem connection. It should also allow the tester to drive the script using random data from large external data sets.

Load testing scripts can be either graphical or textual in nature. Good load and performance testing tools do not require the testers to be programmers. Testers that are not familiar with programming will work with scripts that can be graphically manipulated. Graphical scripts will typically show all recorded steps in the form of a hierarchical structure and testers would modify any of the steps in order to modify the recorded script. Testers who are proficient in programming may want to manipulate their scripts by editing the code. These testers would work with code written in a well known programming language such as JavaScript, VBScript or C.

Once your script has been created, you may wish to put specialized checks in place. These checks would typically be related specifically to the application under test. For example you may wish to check that the response returned by a certain web request meets certain textual criteria. This would involve the placement of a text checkpoint. A text checkpoint can verify that a given text segment is present or is not present in a specified portion of the web page. Once you have finished the creation of the script you would typically test the script on your own machine as a single user to ensure that the test script runs as intended.

You are now ready to perform a performance based load test. A good load testing tool will allow the tester to fine tune the execution of the test. This means that it will allow the tester to choose the number of concurrent virtual users, how the script ramps up, how it ramps down and for how long it runs. It should also allow the tester to create various groups of concurrent virtual users that have their own ramp up, steady state and ramp down characteristics. A good testing tool will allow the user to distribute this load over several machines since a single machine may be only able to scale up to a few hundred users.

To understand the behavior of the loaded web application, it is also important for the load testing tool to enable the tester to track the performance characteristics of external components such as operating systems, web servers, databases etc. This allows the user to see how the performance of his application correlates with the performance characteristics of the external component. This kind of analysis will allow the tester to pinpoint the root cause of performance bottlenecks fairly easily.

During test execution the tester should be able to view the performance graphs in real time for performance metrics such as the transaction response time, HTTP responses per second grouped by HTTP code (e.g. 200, 404, 500 etc), passed transactions per second, failed transactions per second, total transactions per second, hits per second, pages downloaded per second etc. The tester should also be able to simultaneously view the performance characteristics of the external components described above. For an operating system this could be something like the % processor time, for a database it could be the number of writes per second. At the end of the test, the tester would typically be able to view and save this data as a report for further analysis.

Load and performance testing allow you to simulate the behavior of your application under a typical production environment. This will allow you to plan your hardware deployment strategy effectively and ensure that your application will deliver the expected performance characteristics. Rolling out a web application without testing its performance characteristics under expected production loads would resemble crossing a road blindfolded. Load testing is an essential part of the development cycle of a web application and should never be overlooked.

Trusting Digital Reviews

Trusting Digital Reviews

Digital camera reviews are abundant not just online but also in the newspapers, magazines and even TV shows. We often wonder why most digital camera reviews always praise all the digital camera out in the market, that's why we end up getting confused on which product to buy or get our loved ones.

Here's one thing you should never trust regarding digital camera reviews - never trust press releases or reviews that are directly from the manufacturer or advertising office that is directly connected with producer of the digital camera. Why?! Well because these digital camera reviews are never too truthful, or they just give out the good points about their products. I mean, what would you expect, supposing you own your own line of digital cameras and to boost your sales, you release digital camera reviews about your products. Of course you wouldn't point out the bad things or the glitches of your product in your digital camera reviews, because that way you will never be able to shoot up your sales. Press releases or digital camera reviews from manufacturer are always half-truths. Haven't you had any experience with that?! I mean, that just doesn't go for digital camera, remember that brush-blower thingy that you bought over the internet that says it would work tremendously for your hair, but ended not working for your hair after all. Press releases are press releases, meaning that they are aimed to get people to buy the product or to give the product a better name. One more thing that you can never fully trust are home shopping networks and advertisements. As much as press releases, they pretty much pose the same claims about their products. But hey, don't trust me, you can always get them and return them after proving to yourself that it doesn't work. Never mind the time and effort that you've wasted, you chose to listen to a half-truth digital camera review, that's what you get for that.

The best digital camera reviews available are those found in specialty magazines (computer based and technical magazines), special websites catering to techie stuff and unofficial digital camera reviews. Why?! Well because! Because these digital camera reviews are always truthful. These reviewers and critics are never afraid to list down the good as much as the bad points of digital cameras. These digital camera reviews usually points out the difference between the products that a certain manufacturer has released and how it is worse or better than the previous one. These reviewers and critics are also knowledgeable in their craft, so its say to safe to say that they know what they are talking about when it comes to digital camera reviews. One more thing, most of the time, these digital camera reviews are actual first hand experience with the product itself and not just some advertising agent asked to come up with flowery words to capture you and your wallet.

Another best source for a digital camera review is one that you can write yourself. And how can you do that?! Of course, you first need to buy your own digital camera, try it out and compare everything that you do with it to the things that it claims to be. (be careful to read the specs, options and features that you need to try out, be on the lookout for words such as weatherproof, meaning that they are splash resistant as to waterproof that are water resistant. You don't want to get your newly bought weatherproof camera wet, just to prove to yourself that the things they claim are not true). After doing so, then you can write your own digital camera review or reviews, depending on how many things you've learned from your digital camera. Be sure to indicate that your review is an on-hand experience with the product and not just some wild guess.

IBM to offer free office software, targeting Microsoft
www.chinaview.cn 2007-09-19 14:22:33

BEIJING, Sept. 19 (Xinhuanet) -- IBM Corp. is to start offering free programs for word processing, spreadsheets and presentations, in another bid to upset the dominance of Microsoft's Office suite, media reported Tuesday.

The company was scheduled to announce the desktop software, called IBM Lotus Symphony, at an event Tuesday.

The name for the suite is the same name IBM used for its first integrated productivity suite, which it offered in the 1980s but which never took off with customers.

Mike Rhodin, general manager of Lotus Software for the IBM Software Group, said the company brought back the name to "herald in a new age" of productivity software.

The programs will be available as free downloads from the IBM Web site.

IBM's Lotus-branded proprietary programs already compete with Microsoft products for e-mail, messaging and work group collaboration. But the Symphony software is a free alternative to Microsoft's mainstay Office programs -- Word, Excel and PowerPoint. The Office business is huge and lucrative for Microsoft, second only to its Windows operating system as a profit maker.

Microsoft's Office suite of products already faces some competition from Google Inc's online tools, called Google Apps.

Stop Computer Hackers

I have used a computer since about 1993. I love all the things I am able to do with one. And now that my fingers are no longer so nimble I love it even more. I am able to communicate via E-mail and to write using my word processor.

One thing about computers which I absolutely hate is the way some others use their computers -- hacking! Hackers should be jailed without regard to their age. Hackers have caused both you and me to lose a lot of money.

And they are guilty of causing unnecessary frustration and aggravation to those of us who are simply trying to enjoy our computing experience. Hackers are a pitiful group of people with nothing better to do with their time than to cause problems for the rest of us.

I expect I have spent 100 hours trying to diagnose various computer problems over the years. I will estimate that I have spent at least $5000 replacing my computers and in buying software to correct or prevent problems which hackers create.

I read recently that successful computer hackers might also be able to steal your identity. Now that is scary! Viruses, trojans, adware, and slow loading or non-functioning computers are bad enough. But now we learn that hackers could actually destroy your life by stealing your identity!

Why is all this necessary?

Many anti-virus, anti-spyware, and other similar computer protection programs are available. Many, if not most, do nothing to stop someone from placing programs on your computer. Those programs seem only work once a problem has been recognized. They do not stop the problem from being placed on your computer in the first place.

I think I have found a program which will protect my computer from hackers. I have downloaded Security Suite which runs continuously in the background and stops hackers from messing with my computer. The program downloaded in less than a minute. I feel much more secure since the free scan turned up no problems on my computer .

With a full eight week money back guarantee, there is nothing to lose.

If your computer has been acting up, you should at least get the free scan. I am certain you will agree that this product is worthwhile for your peace of mind and for your personal, or business, security.

LCD or CRT - Which One For Me?

LCD or CRT - Which One For Me?

To have a choice sometimes makes things a bit confusing. When there's only one to choose from it's easy. So when you have to choose between LCD or CTR how do you go about it? First you need to find out what you want most; space or quality? Although with quality, the gap between the two is quickly closing. If you are a graphic designer, you might want to stick with a CRT - Cathode Ray Tube - screen for the time being. It seems to have the best resolution as yet.

LCD screens save a heap of space and are light and easy to handle. Resolution is the watchword when buying any kind of screen. The maximum resolution needs to be 1024x768 at the very least. This will enable it to support all your applications and icons. The more pixels your screen has, the better it will be to work with.

The CRT is generally thought to be cheaper, better to view and with better colour depth than the flat screens. But CRTs are falling in popularity, probably due to the ease of use that the flat screen has. It is not heavy and can fit in places that the CRT would not. There is no hot air to contend with as the CRT has, so if you don't have air-conditioning, maybe that's the one you should get.

Introduction to Macro Software

2007-09-19T15:37:00.000+07:00

Introduction to Macro Software

Macro software plays an important role in modern life. But most of you don't know what it is, and how it works. Here is a basic introduction to the software.

The macro software is a powerful utility that collects of several separate applications, all working together to act like one cohesive unit. It is designed for automating the tasks that you perform repeatedly or on a regular basis. The primary purpose of the software is to simplify and make your life and job easier. So if your jobs are plodding and repetitive, you can free from them by using the macro program.

Before you use the software, you should be familiar with the basic usage for macro software.

What's a macro? It is an essential concept you need to know first. A macro is a set of keystrokes, mouse actions and instructions that are recorded, saved, edited. The recorded keystrokes, mouse actions and instructions can be played back (executed) in further. In other words, a macro is a series of commands, keyboard or mouse actions that are recorded to perform a given task automatically when a certain key is pressed or a certain command is entered. These tasks can be something simple from typing your email address into a site to something more complex such as transferring data between two applications.

Knowing what a macro is, you can now create a macro. The macro software allows you to create macros in two ways. The most common method is to create a macro by recording keystroke and mouse activities. When the recording starts out, you can perform the activities or tasks that you want to script. During the recording process, the macro program will track keyboard events and mouse events, and then turn these actions into macro steps. When finished, you stop the recording and save the macro. The other method is to create a blank macro by editing manually. You open the script editor and inset the action list you need, and then you can edit the script for a macro manually. Later, you can use macro editor to modify existing macros and remove unwanted mouse moves or delays and optimize the performance even further. Of course, for the recorded macros, you can use the macro editor to further customize and fine-tune it.

For macro software, there are two ways to play a macro, regular playing and quick playing. For the regular playing, using hotkeys or keywords to replay recorded macros is a simple one. You can specify a hotkey or keyword for a macro, and press the hotkey or keyword to play back it when you want to perform the macro task. The quick playing differs from the regular playing. That means you can schedule or trigger a macro. Scheduling a macro is an ideal way to perform a task automatically without your supervision. You can schedule it to run at a specific time it is convenient for you; or you can schedule it to launch periodically (daily, weekly or monthly). Alternatively, you can launch a macro based on one or more system events. Whenever, a system event occurred and a macro has been triggered with it, the macro will be launched automatically.

Web 2.0

2007-09-18T12:03:00.000+07:00

Web 2.0

Possibly one of the most useless phrase that's currently doing the rounds is 'Web 2.0'. I call it useless as the term implies that there is a new version of the World Wide Web available, and that us fools left using the old Web 1.0 should probably catch on and make the switch; fortunately this isn't the case.

The term was coined by O'Reilly Media 2.0 back in 2003, and was popularised by the first Web 2.0 convention in 2004 and then a series of successive conferences. Eventually it become adopted by the wider community however when a customer of mine asked me earlier today to define exactly what Web 2.0 meant I was stuck; hence my sudden need to write this article.

I don't feel bad for not knowing how to define the standard as even Tim O'Reilly, the man who is credited with creating the term seems to describe it in an incredibly cryptic and nondescript way. Apparently "Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as platform, and an attempt to understand the rules for success on that new platform."

Right, so in English what exactly does this mean? I think the best way I can describe it is to say that Web 2.0 is a term used to describe a website that has increased the overall functionality of the Web; as such, the term can mean different things to different people. Broadly speaking a website that provides new and interactive technologies such as weblogs, social websites, podcasts, RSS feeds and online web services can fall under the Web 2.0 umbrella.

Personally I think that the phrase is a nonsensical buzzword which has been coined for no real reason than the fact that it sounded catchy. Using the phrase in a meaningful way can be close to impossible since many of the core components of Web 2.0 have existed from the very earliest days of the web.

For educational purposes I should really go over the typical characteristics that are used to make up a typical Web 2.0 site and these are as follows:

- Users being able to contribute to the data on a site; Wikipedia is a good example of this.
- An element of social networking such as MySpace.
- Allow users to use applications entirely through a browser. A web operating system such as Goowy which I reviewed several months back is a good example of this.
- A smart and user friendly interface; often based on a new technology such as Ajax.
- An ability for the user to enhance the application or website as they use it.

Our website design company Refresh Creations often gets people touting that their websites are categorised as Web 2.0, but when you delve deeper it becomes apparent that they have simply installed a trivial feature such as a blog to allow them to make this claim.

Personally, I hate buzzwords and have little time for people that utilize them when pitching ideas or sales pitches to me. Therefore it is somewhat unsurprising that I simply don't 'get' Web 2.0 - due to the lack of set standards to what it actually refers to you can end up making the phrase mean practically anything you want it to.

Even after researching this article for best part of an hour I'm still a little bit unsure as to what the phrase actually means and I don't think this is my failure to grasp the concept but rather the fact that it hasn't been correctly, accurately or solidly defined.

CNC Control

2007-09-18T11:47:00.000+07:00

CNC Control

Since we are dealing with CNC machines that do work for us, we need to control those CNC machines somehow. We need to control them for safety reasons as well. If you give a machine improper commands it can easily get out of control and cause harm to you or the part you are machining. We want to give appropriate commands to our machines, at appropriate times so they are not "out of control".

The language that these machines use is called G-code. G-code has been around since the early 60's. There are a number of variations of G-code, but most are very similar to one another. See the previous section for a sample of G-Code.

We will need to use a computer to talk with our CNC machine. Our computer will send signals to our CNC machine. In-between our computer and our CNC machine sits a controller. A controller converts commands into signals that are used to control the motion of our machine.

As these signals are sent out of the CNC controller, they go to either stepper or servo motors. This is how we create motion. These motors drive our various axis on our CNC machine. While we are moving our axis, there is generally a cutting tool of some sort removing material. This is the machining process coupled with CNC.

Here is a brief description of the two types of motors generally used in CNC:

Stepper motors:

Simple design Easy to use Generate torque at low rpm Do not know their position in relation to the program

Servo Motors:

Generate torque at high RPMs Generally need gearing of some sort to be effective More sophisticated Can maintain their relative position, thus, they can be more accurate

CNC Machine Controllers

Controllers generally stand alone near the CNC machine. They act as a translator between your control computer and your CNC machine. Generally, they add quite a bit of cost to a CNC machine as well. Controllers can cost anywhere from $1000-$20,000 or more depending on their sophistication.

Overview of Mobile Framework

Why Mobile Framework is needed?

The need to display content on mobile devices continues to burgeon - especially with the seamless extension of enterprise data onto the small screen. As a result, solutions for shortening the content-to-mobile implementation cycle are on the rise. If you want to take your content mobile, and do it quickly and efficiently, have a look at mobile frameworks.

Purpose of Mobile framework

The purpose of a mobile framework is to utilize a standards-based architecture that leverages existing IT infrastructure and maximizes return on investment. Such a framework is relatively easily deployed and extends enterprise content to mobile users with both good quality and user experience. The purpose of a mobile framework is somewhat different from actual mobile development tools, which are specifically used to develop mobile applications. Mobile frameworks extend existing applications (such as Customer Resource Management (CRM) to mobile workforces and their devices. Just make sure the mobile framework is truly a mobile framework.

Use of Mobile Framework

You're on your way to a pivotal meeting but the flight's been delayed. You need to notify your client, make some last minute adjustments to your presentation, and figure out the fastest route from the airport to their office. In short, you really need to have your office with you. The answer is MOBILIZE YOURSELF! Explains how to maximize the mobility of the technology you have today--and it provides smart answers about the mobile technologies and services you might be considering.

Mobile framework Requirements/Features

This list will help you identify a mobile framework. Usually, a mobile framework will include the following: A graphical development tool that visually maps complex server logic and data to device resident applications

Flexibility for customization and the ability to incorporate new code (MMAPI, .NET, Insignia) Secure access and user identity

An API extension to let other applications "hook" in Enabling of media (video, audio, images) transformation (Java MMAPI, Insignia Mobile Media Framework)

Ability to provide lightweight technology for mobile agent-based distributed computing (Taco Framework)

Ability to provide for content syndication (Jet speed)

Ability to provide content transformation

Agents for device detection

Asynchronous transactional messaging for guaranteed data delivery and integrity Allowance of true mobile client applications with seamless disconnected and real-time operation Mobility is still a new approach to the workplace. Reaching business systems puts special demands and requirements on access, security, and collaboration infrastructure. This can all be reassured with mobile frameworks.

The name MOBILE is derived from the first letter in each of the six categories that make up the framework.The six categories are:

M the need for mobility O the need to improve operations B the need to break business barriers I the need to improve information quality L the need to decrease transaction lag E the need to improve efficiency

Advantages of Mobile Frameworks

So what's important in Mobile Framework is to get the technologies that take you farther and to

# Learn how to choose, customize, and synchronize notebook computers, Pocket PCs, and other mobile devices

# Evaluate your connectivity options--infrared, wired and wireless LANs, cyber cafés, and more

# Make your e-mail, files, corporate data, and favorite Microsoft Office applications road-ready--and secure

# Do more with less gear--get driving directions, enjoy music and video, even manage your stocks and expenses on mobile devices

# Help your company stay agile with sales automation, ERP, and other applications for mobile employees

# Know how to buy accessories and gadgets that aren't just cool, but solve real business problems

Thus Mobile Framework has a large spectrum of different applications, requirements and features. But we Specialties are concentrating on small part of that spectrum and that is "sales automation, ERP, and other applications for mobile employees"

Database Indexing - An Introduction

Database Indexing - An Introduction

Databases are excellent data storage and retrieval tools, ranging from simplistic tables of information to complex, intricate collections of multiple linked databases. A database is created and named based on the particulars of its application, and stores data in tables consisting of an organized collection of rows and columns. Data may be manually entered into databases, but is more commonly written dynamically into databases by web sites or by connected software applications. Companies often maintain constantly growing databases containing data such as client information, financial figures and performance analyses, for instance, and the ever expanding nature of such databases warrants techniques for streamlining the process of locating specific pieces of information within them. Indexing allows for the rapid retrieval of specified data by queries, and is therefore a powerful tool for databases containing hundreds or even millions of records.

At initial set up, the creator of a database typically defines the primary key, which is a column within which the data in each row is unique. For example, a column containing client last names would not be identified as the primary key, as multiple entries may have the same name. However, a column containing unique client ID numbers could be designated as the primary key. When the primary key is defined, an index is actually created. When data from the column defined as the primary key is requested in the form of a query, the database automatically utilizes this index to quickly locate the requested data. However, the primary key is likely not the only column that will need to be searched for data. For queries that will be used frequently, an index can be added to the appropriate column to speed up the process of data selection. Indexes speed up the process of retrieval while lessening the workload the server must endure to perform the search.

Much like the way the index of a book makes finding a topic easier, database indexes make locating a queried piece of data easier. Instead of flipping through and reading each individual page of a book to locate a topic, you can refer to the book's index and know where to look right away. Likewise, instead of a query asking each record in a database if it contains the information being sought, it can be directed by an index to the appropriate data.

Effective use of indexes requires establishing a balance between an efficient number of indexes and too many. Since indexes take up space, using too many can counteract the purpose by slowing the database down. Indexes may be unnecessary for smaller databases, where the queries can locate data quickly and easily. But indexes are dynamic and powerful tools for optimizing the performance of large databases.

$25 Million in Prizes Is Offered for Trip to Moon

$25 Million in Prizes Is Offered for Trip to Moon

The group whose $10 million prize spurred privately financed rocketeers to send a small piloted craft to the cusp of space in 2004 has issued a new challenge: an unmanned moon shot.

With the audacious new contest comes a much bigger prize: up to $25 million, paid for by Google, the ubiquitous Internet company.

The “Google Lunar X Prize” was announced yesterday in Los Angeles at the Wired magazine’s NextFest. The contest calls for entrants to land a rover on the moon that will be able to travel at least 550 yards and send high-resolution video, still images and other data back home.

The X Prize Foundation saw the new contest as one of “the grand challenges of our time that we can use to move people forward,” said Dr. Peter H. Diamandis, chairman and C.E.O. of the foundation.

The prize for reaching the moon and completing the basic tasks of roving and sending video and data will bring the winner $20 million, according to the contest rules. An additional $5 million would be awarded for other tasks that include roving more than 5,500 yards or sending back images of artifacts like lunar landers from the Apollo program.

Carnegie Mellon University immediately announced that a roboticist on its faculty, William L. Whittaker, would be pulling together a team to seek the prize. Why would anyone sign up for a challenge that will almost certainly cost more than the prize will bring? John M. Logsdon, the director of the Space Policy Institute at George Washington University, said: “There are a variety of reasons to do it, including ego gratification, including loss-leader reputation building, including a fascination with doing things in space. I don’t think they’re driven by the amount of the prize.”

Dr. Logsdon said the goal was realistic once a launch vehicle is obtained. “Russia and the U.S. did that sort of thing 40 years ago,” he said. “The technologies aren’t easy, but with all the experience in industrial robots and sensor devices, I don’t see any reason why you couldn’t put together a robotic machine that could meet these requirements.”

The $20 million grand prize will be available until Dec. 31, 2012, and then will drop to $15 million for two years. The contest would be likely to end after that time, though Google and the foundation would be able to extend it.

The new contest follows the path of the original Ansari X Prize, which was won by SpaceShipOne, a manned spacecraft designed by Burt Rutan’s Scaled Composites and financed by Paul Allen, a co-founder of Microsoft.

That prize was paid for through a special insurance policy secured by Anousheh Ansari, a telecommunications entrepreneur in Texas and a board member of the X Prize Foundation who has since orbited the Earth aboard the International Space Station. Mr. Rutan is designing a second generation spacecraft called SpaceShipTwo that will be used by Sir Richard Branson’s space tourism company, Virgin Galactic.

The new X Prize, Dr. Diamandis said, grew out of research performed last year for the National Aeronautics and Space Administration as a contest that the space agency would sponsor. The research suggested that six or seven contenders could be expected to try for the prize, but NASA ultimately backed away from financing the project, Dr. Diamandis said.

Then, in March, Dr. Diamandis pitched the idea to Google’s co-founder, Larry Page, who sits on the board of the X Prize foundation. “Sounds like a lot of fun,” he told Dr. Diamandis. The multimillion-dollar project, Mr. Page said, would be “doable,” but his Google co-founder, Sergey Brin, would have to sign on as well. This also happened quickly, Dr. Diamandis said.

NASA has announced plans to return astronauts to the moon as early as 2020. But without the need to keep humans alive or to make a return trip, the X Prize trips would be comparatively simpler.

A number of successful entrepreneurs from the world of computing and the Internet, like Mr. Allen, have pursued childhood fascination with space with efforts to create real spacecraft. Elon Musk, a founder of PayPal, has developed rockets through his company, Space Exploration Technologies, and Jeffrey P. Bezos, the founder of Amazon .com, is developing rockets at a facility he owns in West Texas.

Roger D. Launius, curator at the National Air and Space Museum of the Smithsonian Institution, expressed enthusiasm for the new competition, which he said “might unleash a kind of furor of innovation” and heighten interest in space exploration.

“It’s certainly a challenge that is worthy,” Mr. Launius said. But he also expressed worries that the robotic adventurers would head to the site of the Apollo 11 landing, a prospect he said was troubling since “the last thing I want to see happen is to see Tranquility Base disturbed.”

Computer Training Course

Computer Training Course

There are several types of computer training course available to the person seeking to learn about computers today. In fact, the whole arena of computer training can be so intimidating that it is good to take your time in selecting what courses you are wanting to take. In this article, we will examine the outline of a computer training course that would appeal to the computer newbie. This course outline is not meant to be all inclusive, nor is it meant to be professional advice for someone looking to enter into the computer technology field. It is simply a broad outline of which subjects are suggested, and in what order, for someone to learn about computers. That being said, let's take a look at our suggested computer training course.

To start, it would be a good course of action to look at classes teaching the basics of how to operate a computer. Information for this computer training course should include things like the basics of using an operating system, how to save information on a hard drive, floppy drives (although they are quickly becoming obsolete), and CD / DVD ROM drives. It is a good idea in the computer training course to also learn some basics about the internal operation of the computer (i.e., what makes it tick, how it works). It may seem like it is best to leave information on how the memory works and what RAM actually stands for to the professionals ... however, this would be a mistake.

It is important even for the average home computer user to understand some of these basics, as it will impact how they use the computer and their expectations of performance under certain work loads and software compatibilities, among other things.

Moving on from the basics, a computer training course should teach more advanced concepts as well. Some of these concepts would include back-up procedures, file maintenance, and data recovery. Security issues are also on the rise, with the increased usage of the Internet, and safeguarding your computer against viruses and other attacks should also be covered in a computer training course. All of these are items that the average computer user should be aware of how to operate. Just knowing this information can save you in the long run from calling that professional for a service call that could literally cost you as much as the computer did in the first place!

Last, but certainly not least, every personal computer user should learn how to install and replace the basic plug-and-play circuit boards or cards that are in every personal computer. A computer training course would simply not be complete without this information. There are many parts that are truly user-replaceable, but unless you know how, you will end up paying that tech big bucks for a simple part swap. Things like that newest video card, an upgraded modem card, installing a firewire card, network card or extra USB port card are very simple.

Unfortunately, unless you are selective in your outline of courses, many basic computer training courses will fail to train you in these aspects of computer maintenance.

Computers In Libraries Won't Replace Books Anytime Soon

The idea of a paperless society has been the dream of computer enthusiasts for many years. Along with the "cashless society", the hope that computers would replace the written word has resonated through sections of American society for many years. Although home computer usage has grown incredibly in the last 15 years making this seemingly possible in the near future, government agencies are slow to catch up. Libraries will have shelves of books for many years too come.

With home computer and Internet usage at an all time high it is no surprise that public libraries are struggling to make ends meet. Research that would have in the past required the use of a library can now be done much faster using a home PC and a few hours on Google. Couple this with the fact that library computers are generally out of date and over crowded, home research becomes the obvious choice. The Bill and Melinda Gates Foundation in association with the American Library Association (ALA) recently funded a study that shows the demand for computer and Internet services has stretched existing library resources to capacity. The study also shows that "more than 73% of libraries reported that they are the only source of free public access to computers and the Internet on their communities". Although there is clearly great demand for these resources, there is little growth ahead. During peak usage hours it is not uncommon in some communities to have an hour wait time for computer access, and only 25% of all libraries report they have the computers to meet demand according to the ALA. Most libraries have not had a substantial increase in computers or technology since 2002.

This lack of technology is doing the most harm to the poor. Americans who have home computers and a fast Internet connection may not realize that large portions of society are cut off from the potential this technology can bring. Many Americans are now at the point where they could not imagine not being able to access the Internet, and the knowledge that would be denied is enormous. As a bastion of knowledge it has fallen to libraries to upgrade their capabilities and help more people access the information they need.

Cost is an issue in upgrading the existing public library technology infrastructure. Tax revenue is still the primary method of funding public libraries, but local government taxes have not been enough for a long time. It has become necessary to increase fines associated with library use and solicit donations in order to make ends meet and provide information services to patrons in need of a computer. Even using older refurbished laptops and desktops that have been donated or purchased has not offered enough saving to allow libraries to catch up to demand.

A new method of cutting costs and reducing computer wait time is wireless networking. By using wireless and Satellite Internet more than 17% of libraries claim they can reduce wait time by becoming a "Wireless Hot Spot" and allowing patrons to access the Internet from their own laptops as well as the library's. This solution also solves many bandwidth issues libraries are having, but not all. Considering that some libraries still use dial-up Internet access any improvement in this area would be helpful.
