Hello All!
I am your humble software/programmer/application designer. You will be immersed in articles ranging from application design concepts, cross-platform development, web 2.0 applications, and cool Linux and OS X hacks that will enhance your experience.
Since I cannot help giving a quick tip at least once a day… here is the first.
Are you tired of having a mouse and keyboard set for each of your computers? Then you are in luck. Synergy is a nifty software application for all platforms that allows you to control many computers with a single mouse and keyboard.

The upcoming post will be “Ajax is your Friend”.

The setup detailed in this guide: a wireless router and a PC with a network card and wireless card. This PC (PC One) will connect to the router via wireless. A network cable will then be connected between PC One and the next PC, PC Two. PC Two will get its internet through PC One.
Go to Control Panel > Network and Internet > Network Connections. PC One will have something similar to the screenshot below.
Right click on the wireless adapter. Now select Properties.
Under the Sharing tab, select the option: “Allow other network users to connection through this computer’s Internet connection”.
Now, select the wired network adapter. Right click, go to Properties. Under the default Networking tab, left click Internet Protocol Version 4 (TCP/IPv4). Now click Properties.
Select the button “Use the following IP address:”. Copy the numbers below into your window. Remember, this is PC One’s wired adapter. Click OK once you’re done.
Under PC Two, go to Control Panel > Network and Internet > Network Connections. Select the wired network adapter that you will be using to connect the cable between the two PCs to. Now, select the wired network adapter. Right click, go to Properties. Under the default Networking tab, left click Internet Protocol Version 4 (TCP/IPv4). Now click Properties. Copy these numbers into the window. Note that this is nearly identical to the previous step, except that the IP address for PC Two is 80.1.1.2, instead of 80.1.1.1. Click OK through all the windows, and you should be good to go. Just don’t forget to connect the network cable.
Following is my experiences with WD’s updated 10,000RPM HDD.
First off, this drive is noticeable when operating, even in an Antec 1200 case. That shouldn’t matter though: the consumers who are usually purchasing one of these drives care more about performance than it dB level. For my comparison I used HD Tune Pro 3.5 and ran the read and random access benchmarks against the Velociraptor (300GB) and my previous system drive, WD’s Caviar Blue (640GB). With it’s built in heatsink, the Vrap also runs cooler than the Caviar. During my benchmarks, the Vrap ran from 21-22°C as opposed to the 24°C temperature of the Blue.
One final item of note: the Raptor drive is obviously going to outperform the Caviar. These benchmarks are not intended to showcase that the Raptor is the better drive (which it is), but to show the performance gains I achieved by installing it in my system.

Comments:
Again, this review wasn’t to pit the Blue and Raptor against each other, just to show the performance gains available to someone in need of an enterprise-class HDD. The Caviar Black would be a HDD worth pitting against the Raptor.
