Everyone has an episode somewhere in their youth involving the use of an aerosol spray as an impromptu flamethrower. Take some mildly inebriated teenagers, given them a deodorant can and a box of matc...

One morning, a balaclava-wearing hacker walks into your office. You assume it’s a coworker, because he’s wearing a balaclava. The hacker sticks a USB drive into a computer in the cube n…

The PC power supply has been a standard of the junk box for the last couple of decades, and will probably continue to be for the foreseeable future. A product that is often built to a very high sta…

We did a bit of looking through the ODROID forums and apparently it’s quite possible to squeeze an impressive amount of performance out of these little single board computers, if you don&#821…

For the last decade, Macs have been running a UNIX-ish operating system on x86 processors. They’ve been fantastic developer’s machines, and the MacBook Pro is the de facto standard lapt…
