We have a calender with all upcomming events on our website. We also announce special event on our mailing list.

Weekly meeting[edit]

Feel free to come by every Tuesday night 19h00 for our weekly meeting! We usually try to cook something and you can always buy something to drink (softdrink / beer).

Since our space opened we are been open every Tuesday with only rare exception. You will find our address and instructions how to enter the building here:

Weekly meeting (practical info)

Coder Night[edit]

The idea is to have 1 or 2 talk about a programming topic. Then there is plenty of time to eat, discuss and maybe even do some programming !

Those event where originally planned to happen every month but are now fairly intermittent. If you are interesting in giving a talk or know someone, let us know.

Some past topics: 20 minute Unity 3D scripting primer, Power of parallel programming with OpenMP, How to rock the house with C++...

More information: (french). (if you don't understand French we recommend you inquire about the language the talk will be given in)
