RGB2Rv18 Codegolf
To participate in this years codegolf challenges, you need to be in the rgb2r wifi and SSH into a special machine:
ssh <username>@golf
When you first connect, your user will be automatically created and your public key authorized for that user. It is not possible to connect without a public key (i.e. there is no password auth). Once you are connected, you can run the golf command to see the existing challenges, submit solutions, see the leaderboards and get further information. After the event, I will copy all the relevant information here.
You can ask Merovius (on RobustIRC) if you need any help or have any questions.
FAQ
Lol, it's so easy to cheat or break this
It is definitely possible and likely easy to cheat and/or break the raspberry pi we use. That means that if you do cheat or intentionally break stuff in a way that spoils the fun for others, the only thing you prove is that you're a buzzkill - not that you are clever. Please keep that in mind :)
What languages are supported?
There currently is a hardcoded list of languages (for uniformity), containing Brainfuck, C, C++, Go, Haskell, Java, Javascript, Julia, Perl and Python. What language to use is determined on file-extension. If you want to use a different language, you can query Merovius a) what debian-packages are needed, b) how to build (if needed) programs for that language and c) how to run programs for that language.

I get some weird behavior when using ssh
Please file a bug against simsim. In the meantime, there is an OpenSSH sshd running on port 2222 that you can use via ssh -p 2222 <user>@golf or scp -P 2222 <user>@golf. User creation, however, only works on port 22, so you need to use that at least once.
