In the world of web development, the choice of which development language to use commonly comes down to two popular choices. Web applications, specifically those relying on back end databases, are typically being created using either Microsoft’s ASP.Net language, or the Open Source alternative language of PHP. Reasons why one might choose one over the other can include: The cost of development tools, or availability of such tools, or even ones comfort level with the Open Source initiative. The goal of this article is to provide some perspective on reasons why one might choose one over the other.

Active Server Pages or ASP has long been an option for creating dynamic web content. Active Server Pages facilitates the ability to use databases such as Access or SQL just to name a few, to create dynamic, feature rich websites. The work going on behind the scenes in serving up the dynamic content is being done at the server level by the Active Server Pages source code. Microsoft has spent a great deal of time and resources promoting their .Net family of programming languages of which ASP.Net is a member. In order to develop with ASP.Net one must obtain the extremely expensive Microsoft Visual Studio Programming Suite. While expensive, Visual Studio is an asset to any programmer due to its vast amount of features. As with all of Microsoft’s products, support and updates are constantly made available for ASP.Net. The shear amount of features that Microsoft packs into Visual Studio, coupled with Microsoft’s extensive support make certainly make ASP.Net an attractive solution for any corporation’s web development needs, but the cost can be prohibitive, if not impossible to afford for the individual web developer.

PHP which is in its 5th revision now, is an Open Source web development language that also facilitates the creation of feature rich, dynamic websites that can use databases. Being Open Source means simply that PHP isn’t owned by anyone. Just as with Active Server Pages, the work going on behind the scenes of serving up the dynamic web content is being done by PHP at the server level. As with most Open Source products, the resources available to a PHP developer are free of charge. This makes PHP extremely attractive to the independent web developer. There are some commercial quality development suites available from companies like Zend, but there is also wealth of free resources just a Google Search away. Because there is really no corporate entity behind PHP, support and development on PHP is done by the community of its users and developers themselves. Surprisingly this does not seem to adversely affect the ability to find support for PHP.

All in all, ASP.Net and PHP are both excellent options, offering basically the same functionality. Whether the decision comes down to the cost of initial investment, or the comfort level one has regarding Open Source, or something else entirely, the end result depends upon the mastery of whichever language is chosen.

Many people are interested in making the most of their hardware. So here are 10 simple tips on how to make your Windows XP computer run faster without having to purchase additional hardware.

1. Defrag Disk to Speed Up Access to Data

One of the factors that slow the performance of the computer is disk fragmentation. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. To speed up the response time, you should monthly run Disk Defragmenter, a Windows utility that defrags and consolidates fragmented files for quicker computer response.

* Follow Start > All Programs > Accessories > System Tools > Disk Defragmenter
* Click the drives you want to defrag and click Analyze
* Click Defragment

2. Detect and Repair Disk Errors

Over time, your hard disk develops bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing difficult or even impossible. To detect and repair disk errors, Windows has a built-in tool called the Error Checking utility. It’ll search the hard disk for bad sectors and system errors and repair them for faster performance.

* Follow Start > My Computer
* In My Computer right-click the hard disk you want to scan and click Properties
* Click the Tools tab
* Click Check Now
* Select the Scan for and attempt recovery of bad sectors check box
* Click Start

3. Disable Indexing Services

Indexing Services is a little application that uses a lot of CPU. By indexing and updating lists of all the files on the computer, it helps you to do a search for something faster as it scans the index list. But if you know where your files are, you can disable this system service. It won’t do any harm to you machine, whether you search often or not very often.

* Go to Start
* Click Settings
* Click Control Panel
* Double-click Add/Remove Programs
* Click the Add/Remove Window Components
* Uncheck the Indexing services
* Click Next

4. Optimize Display Settings

Windows XP is a looker. But it costs you system resources that are used to display all the visual items and effects. Windows looks fine if you disable most of the settings and leave the following:

* Show shadows under menus
* Show shadows under mouse pointer
* Show translucent selection rectangle
* Use drop shadows for icons labels on the desktop
* Use visual styles on windows and buttons

6. Disable Performance Counters

Windows XP has a performance monitor utility which monitors several areas of your PC’s performance. These utilities take up system resources so disabling is a good idea.

* Download and install the Extensible Performance Counter List (http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/exctrlst-o.asp)
* Then select each counter in turn in the ‘Extensible performance counters’ window and clear the ‘performance counters enabled’ checkbox at the bottom button below

7. Optimize Your Pagefile

You can optimize your pagefile. Setting a fixed size to your pagefile saves the operating system from the need to resize the pagefile.

* Right click on My Computer and select Properties
* Select the Advanced tab
* Under Performance choose the Settings button
* Select the Advanced tab again and under Virtual Memory select Change

* Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.

8. Remove Fonts for Speed

Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require.

* Open Control Panel
* Open Fonts folder
* Move fonts you don’t need to a temporary directory (e.g. C:\FONTBKUP?) just in case you need or want to bring a few of them back. The more fonts you uninstall, the more system resources you will gain.

9. Use a Flash Memory to Boost Performance

To improve performance, you need to install additional RAM memory. It’ll let you boot your OS much quicker and run many applications and access data quicker. There is no easiest and more technically elegant way to do it than use eBoostr (http://www.eboostr.com).

eBoostr is a little program that lets you improve a performance of any computer, powered by Windows XP in much the same way as Vista’s ReadyBoost. With eBoostr, if you have a flash drive, such as a USB flash thumb drive or an SD card, you can use it to make your computer run better. Simply plug in a flash drive through a USB socket and Windows XP will use eBoostr to utilize the flash memory to improve performance.

The product shows the best results for frequently used applications and data, which becomes a great feature for people who are using office programs, graphics applications or developer tools. It’ll surely attract a special attention of laptop owners as laptop upgrade is usually more complicated and laptop hard drives are by definition slower than those of desktops.

10. Perform a Boot Defragment

There’s a simple way to speed up XP startup: make your system do a boot defragment, which will put all the boot files next to one another on your hard disk. When boot files are in close proximity to one another, your system will start faster.

On most systems, boot defragment should be enabled by default, but it might not be on yours, or it might have been changed inadvertently. To make sure that boot defragment is enabled:

* Run the Registry Editor
* Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction
* Set the Enable string value to Y if it is not already set to Y.
* Exit the Registry
* Reboot

Do you want to download games onto PSP? Hardly anybody doubts the usefulness and many facets of the Sony PSP, but a lot of people feel that the games themselves are considerably overpriced. If you do your research, you can find the right places and methods to download games onto our PSPs, and we can even do this without breaking the law!

How to Download Games onto PSP- Step 1-
Your standard PSP games will come on disc, or UMD as they are called. As you download games onto PSP however, they will go directly on to a memory stick/card. (Although some people call them memory sticks, and others refer to them as memory cards, there is no difference between the two.) The standard PSP memory card of 32mb will just be big enough to do the job with modern games. PSP owners as a rule should get the biggest and best card within their budget. It is not difficult any more to find reasonable deals on 2 or 4 gig models on eBay and Amazon. When you have acquired your memory card, it will need to be formatted before you can use it. This will effectively wipe the card clean, and is an essential step, so don’t leave it out.

One of the biggest problems is finding a place to download the games from. It is not difficult to find places that will let you download games onto PSP, but so many of them are unreliable and dangerous. Apart from the risk of downloading something that will be different from what was promised, you could even find your computer infected with a virus or spyware. Not good! Make sure you find a reputable site to download PSP games from. The trustworthy ones will charge a small fee in advance, and for that you will get access to unlimited downloads.

As you start downloading to your computer, make sure you only download files that end in “PSP” or have “PSP” in the title, as otherwise the file will not be compatible. Sadly it will often be found that the untrustworthy sites out there will trick you with all sorts of different files as downloads, so make sure you are very careful about a file before you download it. A very good idea when downloading the games is to save them to their own folder on your desktop called “PSP Downloads”. This is the most logical place to put them!

Once you have quite a few games downloaded, you can then transfer therm from your PC onto the memory card of your PSP. This is not complicated, and will only need a standard USB cable to connect the two, and the PC should then accept the PSP and think of it as some form of removable drive, like a flashdrive or removable HD. When everything is connected, you need to open up the PSP using the PC and drag and drop the needed files onto the PSP memory stick, just as you would with any kind of removable drive. It is important that as you do this, you put the files into folders marked PSP, and then GAME on your memory card. You must create these files if they are not there already, and it makes sense to use all capital letters.

As soon as you have transferred the games to your PSP, you should be able to play them by opening up the GAME menu and choosing the game you want from the stick. You may get error massages, and these are often caused by incompatible firmware. This happens most often with downloading homebrew games. It can mean that you have to downgrade the firmware for your PSP to be able to play these homebrew games.

It really is quite easy to download games onto PSP when you have learned how to do it, the hardest part is finding a reputable download source!
