Motion: Use Your Webcam as a Security Camera

Last month, my landlord told me he had to send an engineer to fix the heating in my room. I could not be at home at the time they would come, but they would have access anyway. This is one of the many occasions in which you wish you had a hidden security camera at hand (together with when you want to know if you roommate is really stealing your chocolate and when you suspect…

MailMe: How to Get Notifications Automatically via Email through BASH

In my job, I have to perform calculations on a remote machine to which I connect through ssh. It happens quite often that I have to run a few jobs overnight, if not for days.
