For those of you that have gawked at the fact that there are devices out there … yes, bluetooth devices, that allow you to step away from your computer and have it lock up but only for Windows? Look no further, BlueProximity brings that functionality to linux.
Usually set to a device such as your mobile phone, when your mobile phone leaves the vicinity, the computer will automatically lock itself. When the phone comes back? Bam! Computer is back in action. Amazing eh? It’s got to be one of the most interesting ways of locking a device and now it’s for linux and open source. Totally neato skippy.
