AI is writing more and more of our code. I think that means we need to get much better at reviewing it. We have a lot of tools to practice coding (LeetCode, HackerRank, Codewars, and so on).

Trying a different approach to social media: no politics, no AI spam Most social platforms feel increasingly noisy lately: political arguments everywhere, bot accounts, AI-generated comments, and feeds optimized to keep people angry. OddsRabbit takes a different approach. It’s a community platform focused on hobbies and interests, with politics kept opt-in and AI/bot spam heavily restricted.
