How to Create a Hirens Boot CD Usb Thumb Drive

Occasionally I get a PC in my shop which has a broken or non working cd drive. One of the mail tools I use is a disk called Hirens Boot CD. Yes I know its considered Warez however it is by far the best collection of tools for a PC tech around so I use it all the time.  I will leave finding the actual disc up to you however once you have it you may want to create a USB drive with Hirens for situations when you dont have your cd or the cd option is unavailable.

Launch iPhone Screen Capture Utility From The Command Line

I have an iPod Touch 2G that is fairly messed up and both the power button and home buttons are currently not working properly which makes taking screenshots much harder than normal in iPhone firmware 2.X and 3.X. If you have installed Cydia however on your iPhone or iPod Touch then you can launch the screen capture from the command line without issue. Once you have taken a screen capture you can then email the photos to yourself or SCP (Secure Copy) them to your computer. To launch the iPhone screen capture utility from the command line follow the directions below.
