Some of you might remember when we tested some security gadgets two months ago, and found a nameless cheapo USB security lock gadget seriously lacking.
The idea was good (walk a way from your PC and it gets locked automatically). There wasn't anything wrong with the hardware, but the software was useless.
The good news is that a guy called Bryan Batchelder has taken the hardware and written software for it that actually works. Have a look at his blog for details.
