It’s very common to hear complaints from people whose computer has slowed down to the point of a crawl.  Over time a computer will tend to slow down.  When this happens most people seem to think that they have to go out and buy a new computer system.  The simple truth is that it’s not necessary to do that.  You can actually speed up your sluggish PC by cleaning it out and making a few small changes.  Most people out there are not very computer literate and have no idea how to do this.  Read on to find out some strategies to help speed up your computer so you can get new life out of it!

Add More RAM

Adding more RAM to your computer is a very easy way to speed it up.  RAM stands for Random Access Memory, and it’s basically a measure of how many tasks your computer can do at once.  It’s just like working at a real, physical desk, and the RAM is the size of the desk.  The bigger your desk the easier it is to multitask on the same desk.  More RAM means a bigger virtual desk for your computer to work with, allowing it to run more programs.  RAM is incredibly cheap these days, and you could easily double your RAM and double the speed of your computer.

Clean The Windows Registry

There are a few different opinions regarding cleaning out the Windows registry.  Even Microsoft seems to recommend cleaning the registry out, like they say on their Windows OneCare website.  If your computer has been running for a while then cleaning the registry might help you out.  If you want to clean the registry you should definitely use a registry cleaner software program to do the job.  There’s quite a few good programs on the market that are safe and easy to use.

Clear Temporary Internet Files

One surefire way of clearing out more disk space on your hard drive is to clear out the temporary internet files.  Quite recently I was helping a friend with her computer that was running very slow .  One big reason it was slow is that the temporary internet files had filled the hard drive to the brim.  One rule of thumb is that you should only fill the operating system hard disk up half way, otherwise it will probably slow down.  You can use a software program to thoroughly wipe out all the temporary internet files and folders that reside on your computer.  Check out our PC Health Advisor review for more information on a great program that will do all this and more.

Microsoft COO Kevin Turner has announced the launch of Windows Phone 7 in Europe and US. But the Aussies are puzzled about their launch Down Under!!

He has announced that Windows Phone 7 will be launched in Europe around October, and for the US market in the month of November. This he said while giving a presentation about Microsoft’s next-generation mobile operating system targeted for consumers. The features of the Windows Phone 7 also include the radical re-designed structure, Zune support, Xbox integration, and more. The wait is just a short little longer.

With the final version of Windows Phone 7 getting ready to be released in October and November, the manufacturers have a quite a lot in store to deal with.

Two more added to the list of Windows Phone 7’s limitations:

1.

Windows Phone 7 lacks the simple feature nowadays available even in a basic model. It is a well known fact that it uses background pictures in the unlock screen and the photo hub but the place where everyone would prefer to have it is, on the start page which as of now be cannot be changed. This won’t affect a majority of WP7 fans, but this was not expected in a Smartphone of the twenty first century.

2. NO CONNECTIVITY IN HIDDEN WiFi

The current version of mobile given out to developers (dev phones), cannot connect to hidden WiFi Networks, ie., for those WiFi networks  that do not broadcast their SSID. For the purpose of security, it is always recommended to hide your SSID with a strong password set in WiFi. But in the case of Windows Phone 7, you will have to keep it visible to browse on this network again.

Two more reasons for us to dump even before launch

Release of the Exilim Card EX-S200 and Exilim Zoom EX-Z800 cameras was announced by casio, marking the latest additions to the Exilim family of digital cameras. Both cameras sport advanced features in a slim, compact and stylish body, including a Super Resolution Digital Zoom that extends the zoom range.

The new cameras make use of the Exilim Engine 5.0 and super-resolution technology to take photos with exceptional clarity and resolution, while the Super Resolution Digital Zoom maintains image quality through 1.5 times the range of the optical zoom. Other features include the highly-regarded Premium Auto function, which automatically produces beautiful photos with just a press of the shutter button.

The EXILIM Card EX-S200 is a slim, high-quality, card-sized camera that is just 17.8 mm thick and only 14.9 mm at its thinnest part, while the EXILIM Zoom EX-Z800 is compact enough to fit in the palm of the hand. Both cameras sport a 4X optical zoom lens that starts at a 27 mm wide-angle view (35 mm film camera equivalent) and is capable of taking images with an effective resolution of 14.1 megapixels, while packing numerous other camera features such as Casio’s CCD-shift image stabilization mechanism in a slim, compact and stylish body.

The EX-S200 uses a flat lens barrel and lens ring to achieve a thin and stylish card-sized body that smoothly combines contrasting geometric shapes. The camera was designed with an emphasis on functionality and simplicity, achieving a design that is at once elegant and understated. The EX-S200 comes in five different colors: silver, orange, blue, black, and pink. The Quick Mode function powers on the camera with a press of the shutter button, previews a photo after shooting, and automatically powers down. Combined with the portability of the card-sized body, Quick Mode ensures that the user will never miss a photo opportunity.

The lens, LCD monitor and buttons of the EX-Z800 are flat to achieve a compact body that fits the contours of the hand. The EX-Z800 comes in six different colors, ranging from basic black and silver to vivid pink, red, yellow, and blue. The polished finish of the camera gives it an elegant yet dynamic look. The camera features dedicated Shoot, View and Delete buttons that provide access to each of the basic operations of a digital camera, so that even beginners will find the digital camera easy to use.

Casio’s unique Dynamic Photo function creates composite moving images, making it possible to have multiple characters moving independently of each other against a background of moving images up to as long as 20 seconds. The Art Conversion function takes saved images and makes them look like artwork. These features make it possible to enjoy photos in a way that is only possible with a Casio digital camera.

EX-S200/EX-Z800 Features:

• Super Resolution Shot delivers images with exceptional clarity and resolution – Both cameras use super-resolution technology to analyze and optimally process the respective areas of the photo that are contoured, textured or flat, delivering photos of exceptional quality and resolution.
• Super Resolution Digital Zoom extends the maximum telephoto range of the optical zoom - The two cameras use super resolution technology to respectively enhance edges, flat areas and textures when enlarging images, by analyzing and adjusting the contours in images and the relief of the subject. The Super Resolution Digital Zoom extends the maximum telephoto range of the optical zoom up to 1.5 times, while reducing image quality degradation. Both the EX-S200 and EX-Z800 offer an optical equivalent 6X zoom range that maintains image quality for 14.1-megapixel high-resolution photography when using the optical zoom with the Super-Resolution Digital Zoom.
• Premium Auto function produces beautiful photos with just a press of the shutter button - Premium Auto enables the camera to automatically analyze the scene being photographed — including distinguishing night scenes, back lighting, a blue sky, green trees or a sunset — as well as sensing whether there is a face in the frame, the movement and position of the subject, and whether a tripod is being used. It simultaneously optimizes settings for exposure, ISO, sensitivity, focus location, photo blur correction, tonal range and color balance, and level of noise reduction. Images are analyzed pixel by pixel to apply different correction to people and backgrounds. Premium Auto delivers an advanced level of full auto photography, ensuring high quality photos with just a press of the shutter button.
• Dynamic Photo function for creating composite moving images – These cameras offer Casio’s original Dynamic Photo function, which makes it easy for users to create “moving photos” right on the camera by cutting moving subjects from the background in images taken with continuous shooting, and combining those images on a different still or moving image background. With Dynamic Photo on these cameras, it is possible to make multiple characters move independently of each other against a background of moving images up to as long as 20 seconds. These capabilities not only make it more fun to create images, but also offer the fun of sharing images by making it easy to upload images to YouTubeTM using the included software or post them to a blog.
• Art Shot and Art Conversion functions create photos with the look of a painting - The Art Shot function makes use of the image processing technology in Exilim Engine 5.0 to create photos of scenery or human subjects that have the look of an oil painting, crayon, or a water colour. With the Art Conversion function, it is now possible to apply the same look as the Art Shot function to saved images.

Retrograde melting is one of the most counter-intuitive phenomena that nature has to offer. Why would some materials melt when they get cooler when everything else melts when they get warmer? Well, technically speaking, there aren’t any individual materials that obey this rule. Instead, very carefully designed mixtures can create the perfect set of conditions needed to make a material liquefy at temperatures far below its natural melting point.

Let’s look at how this trick was recently accomplished with silicon. Using a highly specialized device that gave them precise control over the heating and cooling processes, a team of MIT researchers essentially created a chemical “sandwich” with silicon as the bread. In the middle, they placed a mixture of copper, nickel, and iron, and then they started heating up the sandwich until these three metals melted and dissolved into the silicon. Crucially, they remained below silicon’s melting point of 1,414 degrees Celsius.

With this accomplished, they then started cooling the newly created compound down. As the mixture reached 900 degrees Celsius, it became supersaturated, which means there was now more metal in the silicon than could occur under stable conditions at that temperature. At that point, a process of precipitation began, in which the metals were forced to melt into a liquid and dissolve out of the silicon. Some of the silicon also melted during this process – at a point 500 degrees lower than would otherwise be physically possible.

The side effects of this process could have tremendous benefits for the production of computer chips and solar cells, both of which use silicon as a primary raw material. The precipitation process attracts impurities in the silicon towards the liquid portion, leaving the more pure silicon behind as a solid.

Solar cells in particular would benefit immensely from this, as even small impurities can greatly impede their performance. A retrograde melting treatment would allow manufacturers to use less pure silicon in the production of solar cells, which would make such cells far less expensive than they are now. In the computer realm, this discovery could aid the creation of better silicon nanowires, which are small, extremely conductive tubes, which again need to be as purely silicon as possible to work.
