In the present internet world, almost every home has a computer. You may use your computer for personal or business reasons, but you certainly have to look for software and applications that you need.

Apart from the operating system, several applications including antivirus are essential for computers. Without protecting your computer, you cannot be safe. To find utility software, you have to search on the internet. You may find many commercial products that provide best service. However, if you want to save money, you have to look for free software.

Many people think that free software is something junk or garbage. They think that they cannot find a software with good features at zero cost. This is absolutely false. On the internet, there are several experts who wish to help their peers. These people design excellent applications and give them for free to make them popular. Also, you won’t have to worry about copyrights issue while using the software as the software is available for free. Just like commercial products, you will find updates for free software as well. The user interface and features will be definitely competent if you find a right software.

Antivirus program is an essential software that must be present in your computer. Without antivirus program, you cannot work or browse safely using your computer. Several websites on the internet provide free antivirus download.

Avg free 8.0 is a very popular antivirus software that can be downloaded and used for free. This is a well known antivirus tool used in several thousands of computers in the world. Installation and use of Avg free 8.0 is easy even for a novice computer user. This software gives protection against viruses and spyware.

When you choose antivirus programs, you have to make sure that you download only legitimate ones. If you don’t choose a proper program, you are at the risk of increasing computer vulnerability. Just because a program is advertised as free, you should not choose it.

Free antivirus download such as Avg free 8.0 constantly updates its database to protect your computer against latest threats. This is an important feature that you have to look in any antivirus program. Moreover, you have to be provided good customer support by the developers. When you start using any software, you are likely to get many questions and it is important that all your questions be resolved to make the software usable.

Free software has to be downloaded from internet with more caution. Several spammers and malicious programmers send out spyware and malware along with some software and make them available for free. You can escape from scams, when you download free antivirus download from legitimate websites. These websites don’t give you torrents for download. So, you can be sure that the file you download does not contain virus or any other malicious program. Legitimate websites provide you access to many free applications more than just antivirus programs. All those downloads are freeware applications that can be downloaded and used as many times you want to as many computers you need.

We’ve all seen LCD touch screens at work around us. Anyone that’s ever used their credit or debit card to make a purchase at the grocery store has to swipe their card through a reader and then use a pen to select and sign the signature line on a touch screen. Versions that are more sophisticated can be found in Photo Centers that allow consumers to print their own pictures or create Christmas cards from disks or memory cards found in your local Longs or Target stores. However, the LCD touch screen is beginning to make inroads into other areas, as well.

One of the first companies consumers think of when the “touch screen” is mentioned is Apple. Their familiar items such as the apple ipod touch and the apple iphone use a touch screen to allow the user to navigate without the need for buttons or trackballs. This is not the limit of their uses, though. The home computer market is now seeing a number of computers available with LCD touch screen functionality.

How does an LCD touch screen work? In essence, it is no different than using a mouse or the touch pad on your laptop, though touching your monitor screen may seem counterintuitive to many consumers (after all, don’t we go to great lengths to keep our fingerprints off them?). Touch screen monitors essentially look like regular lcd monitors but are equipped with additional features. Basically, a touch screen is actually just another piece of hardware. A thin film of touch sensitive lamination (clear) is placed over the computer monitor; this is then wired into the computer. The pressure from your finger is transformed into an electric signal, which is then sent to the CPU.

There are two main types of touch screen monitors on the market today: add on systems and built in systems. Built in systems come ready to use in the box, just plug them in and go; though you will most likely need to install the software drivers first, if your system was not designed to use a touch screen. Add on systems are installed by the consumer over their existing computer monitor and then plugged into an accessory outlet on the computer. Once again, device drivers are required to tell the computer how to recognize the signals.

Touch screen monitors like the ipod touch and iphone will be affordable for the average consumer while POS (point of sale) touch screen monitors will be geared more towards businesses. And how can we forget to mention the glamorous touch screen displays as seen on CNN and ESPN? Yes, those are very large touch screen monitors. I’m sure you saw one in use during this year’s election when CNN used it to track the Democratic and Republican States. These gigantic displays just mentioned will only be affordable, and needed, by a few.

There are a number of popular manufacturers creating these devices today. Some of the most popular are Planar, GVision, Megavision, NEC and HP. Do your research, regardless of the brand that you choose, though. User forums and reviews can give you the information you need to make a good purchase in a device that will perform well for years to come. If you are a small business to medium sized business, make sure you check for discounts.

The very technically minded amongst us will know exactly what an API is. For the rest, a short explanation is in order. API stands for Application Programming Interface and without this little software creation that powerful graphics card sucking up everything it can from both your PSU and bank balance would be so much circuitry and scrap. APIs allow the treasured hardware inside one’s machine to function correctly. It uses function calls to direct the resources available and allow, in the case of a graphics card, rendering and other more advanced functions to take place.

The major point is that there are only really two graphics APIs worthy of notice. Much like the NVIDIA/ATI divisions that are the subject of almost every tech-forum, API usage is spilt into proponents of DirectX, the current market leader and the brainchild of your friendly neighborhood Microsoft, and OpenGL, the resident underdog that could still turn DirectX on its ear.

What’s the point?

Both OpenGL and DirectX have gone through many incarnations since their inception and cataloguing absolutely everything is a job for Wikipedia. There have been some major differences over the years that have set each apart from the other and it is these which are of interest. OpenGL and DirectX have used completely different methods from the very beginning; with the line between the two blurring in later versions. We’ll find out why this is the case, though some can spot why right off the bat.

According to Microsoft

DirectX is Microsoft’s favorite little creation, allowing them to wield the banhammer on a lot of folks by virtue of its proliferation. Direct3D is the major component in DirectX, supporting only Windows systems and pretty much anything else Bill Gates has touched. It is even the base software for the Xbox and the 360. Created to deal with 3D applications and graphical rendering, Direct3D handles all of those nifty features that show up while setting up options in your latest game. It controls hardware acceleration, should the hardware be capable of using it. Functions such as anti-aliasing and texture mapping are also handled, as is everything else to do with the GPUs 3D functions. Software emulation of certain bits of a GPU are also picked up by DirectX. Direct3D can emulate vertex software but it cannot do as well with pixel shaders. It’ll allow an image to hit screens but it will be of shocking quality.

Open source opinion

OpenGL is Microsoft’s open source competitor but the major battles are now confined to the past. Some folks still code games to take advantage of the API but it is often sitting side by side with the Microsoft equivalent. Being open source, there is no real limit to the number of versions out there but a stringent qualifying process is needed to qualify for the OpenGL standard. OpenGL is the default API for almost everything that is not Windows-based, running the iPhone, most of Sony’s consoles, some of Nintendo’s hardware and Mac and Linux-based systems. It also runs on Windows but has none of the exclusivity that Direct3D enjoys. With this wide base of operations it should seem remarkable that DirectX holds so much sway in the API arena.

Head to head

Each API has positive and negative points. Some are valid or can be corrected or lived with. Others are nigh unbearable, forming the bane of programmer’s and end-user’s existence. Let’s start with a few of those.

Microsoft’s DirectX is a completely proprietary system, functioning only on selected hardware. In case it was not clear, this translates to Microsoft only systems. Other problems have included the standard Windows bloat for programs which appears to crop up in some of their software. Even the almighty XP has been guilty of this failing. Other cons for DirectX only appear on direct comparison with the competing API.

The fundamental differences in how DirectX and OpenGL go about their business are miles apart. DirectX has tended to focus on the capabilities of the hardware itself without giving much thought to additional features that may lie outside the realm of the GPU in question. The software allows whichever features a card may hold to be utilized by a system and beyond that does not concern itself much with anything else.

OpenGL has been about creating a system whereby all possible features are made use of, either by driving a card’s inherent capabilities or by using software to render as much as possible. In the case of OpenGL software is the de facto method of driving a 3D application, with hardware acceleration being used if it is available.

Seeing the difference in approach between the two APIs, OpenGL appears to have a much more robust and potentially more powerful application. With software rendering being the first line and acceleration being secondary, OpenGL’s capabilities at running a 3D application would be higher than DirectX’s, should the system they are running on have identical hardware.

The best way to keep computer safe
Computer security is a very vital and a very important aspect of the computer, especially when your computer has a lot of vital information and documents that you cannot afford to loose.
A lot of computer users suffer from data lose as a result of poor computer security. If your computer is vulnerable to virus attacks, you are likely to experience computer crashes and heavy data lose.
Keeping your computer safe and secured is just like owning a car, fueling it, washing it and changing oil, makes your car gives you maximum performance.
In this article I will be sharing with your some step to take in other to keep your computer safe and secured.

1. Limit your account user right

If you have an administrative right on the computer that means you can install any thing and also perform any system configuration on the computer, so also viruses using your administrative right can install themselves on the computer and also enter registry values. But when you limit your user right to a power user, no auto run file will be able to run on your computer without your permission and also no system configuration will be done on your machine without your permission, but when you want to install a program you right click on the program and click run as then enter the admin user name and password. Or you log of the current user and log in as administrator to install or configure your computer.
How to Change your user account right can be found here. This is the first step in keeping your computer safe.

2. Use Internet security software

Using a good internet security will not only keep you safe from viruses it will also monitor spyware and malwares also it will monitor your internet connections and sites that are harmful to your computer will be blocked
A good internet security should be updatable offline, easy to use and configured, and must be able to dictate harmful programs and sites and prompt for user action to run or block.
Remember that you have to make sure that your antivirus solution is consistently updated.

3. Perform system cleanup regularly

Performing system clean up erases all the junk files that accumulate memory in your computer. If you clean up your computer regularly, your system will run faster. How to clean up your junk files read the article here.

4. Scan external drives:

Because you never can tell if an external drive has a virus by merely looking at it, you need to scan any external drive attached to your computer before using it.
Lastly scan your computer frequently so that if any infectious file has entered your computer, your internet security will remove it.
If these steps have been taking, you are on your way to keeping your computer safe and secured.

Fax Machines on ShoreTel? It is not uncommon for system administrators to create a user named FAX SEVER, then define it as EXTENSION ONLY. Though I personally have been trying to eliminate all the forest eating fax machines and printers on the planet, it would appear that Fax machines are going to be with us for quite some time. Even with a fax server, people want to stick a piece of paper into the machine and watch it “go through” after dialing the distant end. This is an example of “Experiential compatibility” as the marketing folks like to say. We are more comfortable with a technology that is compatible with our experience.

Often, there are other analog devices that survive the move to IP telephony. For example, the credit card machine! Many company’s will have another ShoreTel user named CREDIT CARD and it also is defined as EXTENSION ONLY. These devices share one common trait that many clients find very annoying. If you connect a fax machine or credit card machine to a ShoreTel analog port, the device will now need to know how to “dial 9″ to get an outside line, to complete a call. So these means that you have to reprogram the fax machine and the speed dial lists that most companies have accumulated over the years. Not an exciting thought and a great waste of human resourcess.

Is there a way to “hack” l the ShoreTel configuration database to just connectthe fax machine to an outside line without the need to “dial 9″? The answer is yes, there is a way. I hope that you have watched enough of my stuff to have loaded a copy of SQLyog on your ShoreTel Server by now? In the MySQL configuration database for the ShoreWare sever, there is a data table named “USERS”. In the USERS database, look for the column labeled EXTERNAL DIAL TONE. Find the USER of interest, in this example FAX MACHINE, and locate this column. You will find that the existing default value is 0, requiring the user to “dial 9″. By changing this value to -1, the user is directly connected to an outside line and is able to dial without using an access code. Be careful changing this configuration database! If you do not know MySQL or SQLyog, you should probably find someone who does. The film clip accompanying this blog will walk you throught the configuration change. Enjoy!

Laptop screen scratches are highly annoying. They interrupt in your work. A single scratch requires immediate laptop screen repair. Any neglect on your part can damage the screen display and cost heavy on your pocket. Hence, an intelligent user should mend the screen as soon as a scratch occurs. After all, who likes to work on a laptop which has damaged screen display.

Ideally, you should appoint an experienced and competent technician to conduct the laptop screen repair task. Don’t avail into cheap technicians who use second hand or pirated parts for laptop repair. Remember, cheap repairing techniques can deteriorate your laptop screen. Hence, you’ll be left with the option of buying a new laptop which would have serious impact on your budget.

If you can’t avail into a technical expert, then you can use this technique to repair the screen yourself. This is known as petroleum jelly method. This technique works with small cuts. Take a cotton ball and dip it in some petroleum jelly. Now, apply it on the scratched area. Take a new cotton or damp cloth to rub the petroleum jelly across the screen. Rub till the scratch blends with the laptop screen.

If this technique doesn’t work, then buy a laptop screen repair solution. This solution is rarely available hence you can also use a CD cleaner. You can also buy the screen repair kit for yourself. It has the necessary solution and instructions to repair the laptop screen. You can follow them step by step and repair the laptop yourself.

This technique works in most of the cases. You can also check Internet laptop repair websites. Several websites provide tips and tricks to repair the laptop screen. These websites and tool kits are alternatives to solve the issue with minimum investment but the safest mode is to appoint a technical expert for the task of screen repair.

So, don’t neglect the scratches on your laptop screen. Get the laptop screen repair immediately.

As compared to the past, the satellite today has moved miles ahead. Today, the GPS unit can work from any weather conditions with the availability of a signal from three to four signals. With this in place, the satellite is able to calculate the unit positions. The GPS does not require subscriptions like the case is with mobile phones, although some of the GPS have extra features which require a monthly charge. This includes real time traffic updates like it is with Garmins Nuvi that has free life traffic for the specific unit.

The parallel multi channel design deserve all due thanks for the accuracy that they have instilled in the GPS today. These satellites have features that enhance quick reaction. Not only do they lock onto satellites but they maintain their stand on lock in even a place that has a close proximity of buildings for instance a city. They have the capability to maintain signals to a level of not below eight satellites. If in any case they fall to the eighth signal connectivity is still experienced.

After the wide area augmentation was developed by the Federal Aviation Administration. There came a lot of dependency on it other than the purpose it was made to serve. It was originally aimed at augmenting the global positioning system to enhance the accuracy, availability as well as integrity. This came as a great advantage as it was later used widely to measure tiny variations in signals and most of the GPS receivers are heavily relying on this system today.

The stations in this case are quite vital because they are used in measurement as well as sending references of messages to the geostationary satellites which are WAAS enabled. Accuracy in this case is improved as computation takes place on the earth as a result of correction messages being send as data for the computation process. With the competitive market that we have today, much has been achieved since WAAS enabled GPS have proved accuracy working within proximity of three meters hence securing the best position in the market today. This GPS is capable of tracking your car by indicating the direction it is heading as long as you have the mapping that bucks “lane assist” direction. These satellites are currently rocking the market bearing in mind that we have no charges imposed on them than it is the case with cell phones.

The GPS systems has not only been useful in tracking but also in the field of political issues as it is widely used by different governments today in communication using radio call based devices. Countries are able to communicate securely via encryption and decryption of information. The advancement is still at a demanding pace and it is hoped to penetrate quickly in to the market.
