I hadn't thought about these in a while, but what happened to Topcoder, Code Jam, etc.? I did some quick research and saw that those two shut down in 2023, but there wasn't much explanation as to why. I thought of this because people keep talking about how productive they are with LLM coding tools, and I thought it would be fun to put the people proclaiming this (along with their LLM tools) up against people not using LLMs in a topcoder competition. Turns out, those competitions don't exist anymore and I'm sad.
If you're looking for a community, there is also an IRC channel named #algorithms on Libera where competitive programming discussions are on topic. The channel is not officially associated with the Codeforces community but there is some overlap, in the sense that some people who are active on Codeforces also spend time there. Visit <https://web.libera.chat/#algorithms> to join the channel via the web gateway.
Disclosure: I am one of the people who has been operating this channel since 2007, first on Freenode and later on Libera.
