Some useful links:

Chronocontrol - a little program that forces to take breaks in a regular intervals. I do a lot of coding, and this program saves from aching eyes, headache, and useless work. 

Changedetection - a free web service that allows you to track changes on static webpages. I use this to track some 50 economists in whose work I'm interested in. This tool sends me email every time a new paper shows up on the web.
