Which computer lab has free PCs?

This post is over 5 years old, it may be out of date.

Since recently, the website welke.tk shows which computer lab has free pc’s. Advantages of this site over the existing current usage page are that it is realtime and that one can immediately see whether a lab is or will be reserved for lectures. The website welke.tk can be viewed on smartphones too. The website has been created by Bas Westerbaan in cooperation with C&CZ, the design was made by Judith van Stegeren, Ruben Nijveld helped with mobile support. The source of the reserved hours is Ruuster.nl.
