The dJulkalender is the CS chapter's very own advent calendar where every door is a challenge. The challenges are within e.g. computer security, the internet, algorithms, programming languages, Unix, hacking, nerd culture. The doors get harder over time such that everyone can participate from the start, but few get to the end. Compare yourself to your friends on the live leaderboards in META.
==> We are looking for authors for calendar doors, web designers, story writers and especially TESTERS for the calendar doors. Email [email protected] if interested.
