2948 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

  3. Pattern Recognition advanced

    Discord's Read States service was fast most of the time but showed latency spikes every two minutes. The pattern looked familiar to anyone who has seen a service under load. The cause published in 2020 was Go's garbage collector scanning a large LRU cache. What does this teach about pattern recognition, and which check would have got there faster?
