Nice, you have experience in data frames in R, Python and Julia! Which one of those do you like the most? I know that the ecosystem isn't really comparable, but from your experience, which one is the best to work with for core operations, etc.?
Problem with that is that you will probably have a downtime for several minutes (or at least many seconds) each day. That's not optimal for a site where at any time of the day thousands of people are playing chess...
Somewhat offtopic, but sesse.net runs a Stockfish instance with the (probably) deepest analysis of live chess games: http://analysis.sesse.net/
I visit it daily for the Chess World Championship match.
These type of repositories have existed since the first Hacktoberfest. They might even be useful for beginners to learn how to prepare their first pull request. But the idea of Hacktoberfest is clearly not to submit all your pull requests to such a repository.
It even seems as though DigitalOcean is blocking these type of repositories. From the FAQ:
My pull request is marked as being on an excluded repository. What does this mean?
Unfortunately, your pull request was made on a repository that doesn’t align with the core values of Hacktoberfest. We’ve decided that pull requests made to this repository will not count toward completing the challenge.
I'm as well a long time lurker. Whenever I contribute something, I feel that it should be helpful for many other people out there. This comment probably isn't...
