Generally when we think of shell scripts we think of editable text, but it's possible to add binary data to your shell script as well. In this case we're going to talk about adding a binary payload to the end of your shell script.

If I play video games they're usually pretty low tech ones. One of the few games I miss from the old days is Duke Nukem, and I'm talking about the Duke before he went 3D. If you have an old DOS game that you'd like to run, or for that matter any old DOS program, check out DOSBox.

In my ongoing quest to take over the world with Linux as my OS of choice, I've noticed that simply handing someone an install CD doesn't really do the trick. I've also noticed that formatting their Windows 95 install with a fresh version of Linux tends to make angry faces as well. The more tech savvy the user is, the more resistant to change they tend to be.

ScaleMP's vSMP Foundation aggregation platform enables the creation of high-end x86-based symmetric multiprocessor (SMP) systems, providing superior performance at prices significantly lower than traditional SMPs and comparable to managed x86 clusters.

Technically, the Noahpad from E-Lead Electronic is a Linux-based UMPC, or an Ultra-Mobile PC. Generally speaking, a UMPC is smaller than a notepad and bigger than a Mobile Internet Device (MID). But, in fact, the Noahpad is so versatile and odd, it may deserve another category entirely.
