Yes, SnowCamp is unique and in Grenoble, it will drive you NUTS!
SnowCamp will be held on a Thursday and a Friday so we can go skiing/snowboarding/sledging on the Saturday. But there will also be a university day on Wednesday for those who want to learn a new technology.
To avoid being just another conference (even with snow) SnowCamp is an opinionated conference.
Various talks (Web, IoT, Cloud, DevOps, Big Data), lightning talks from PhD students, researchers and even from people who code.
But it is also an unconference Saturday on the 11th of February, we can can all meet on the snow slopes for fun.
