When I first got into CP, I'm pretty sure I saw on Benq's github https://github.com/bqi343/USACO a calendar with a bunch of programming contests, including some on camelot.ai which had fairly regular schedule of these beginner's contests in data science where you'd use pandas in python. I have no background in programming and actually really liked how the website mixed learning new stuff with a contest-style format.
Then I think the website just died, and now it's back and it's totally different. Does anyone know what happened to the original camelot.ai (did it move domain?)?
