Frequently Asked Questions

What are the keyboard shortcuts?

We do use Ace Editor, the shortcuts are documented here.

HackInScience has one shortcut: Ctrl-Enter to submit an ansser.

Do I loose ranking points if I submit wrong answers?

No. Your ranking is only base on the exercises you solved and when you solved them:

  • Solving more exercise will guarantee a higher ranking, even if late.
  • In case of equality, ranking is disambiguated using who solved what first.

Can't connect to correction server?

If you have the correction server connection error, there's two main possibilities:

Either your internet provider (or VPN, or ...) blocks WebSockets, in which case you should politely ask for them to update their blocking policy.

Or my server is down (in which case you should not even be able to read this message).

Anyway don't hesitate to open an issue in the bug tracker, so I know.

My question is not in the FAQ, how to add it?

How do team works?

Teams are named groups that have their own leaderboard.

Anyone can create a team at any moment, and leave a team at any moment, but:

  • Joining a non-existing team creates it, you become the team staff, you and only you can now grant new members in the team.

  • Joining an existing team marks you as willing to join, you'll have to wait for the team staff to accept you in.

By default a team is public, shoot me an email if you need a private team.
