Distributed systems are mostly theory until the first partition; after that, they’re mostly operations. The theorems still matter - they tell you which failure modes are unavoidable - but the day-to-day is timeout tuning, replica promotion drills, and arguing about whether “eventual” is good enough for this particular counter.

Posts under this hub land as I write them; right now /stack/go and /stack/kafka are the closest pointers to operational practice in the repo.
