if you haven't read the factorio devblog before, please do!

after HN, it's one of my favourite places on the internet because i constantly learn new, random, insane things almost every time. imho it teaches you how to think + shows you what great engineering taste looks like. sorry if i'm overly effusive but each post is so deeply technical and well-written that i can't believe it's free.

you don't need to know anything about factorio or gamedev btw (i don't), just pick a random number between 1 to 438 and start reading :)

Yep FFF is such a treat to read. They do an amazing job of explaining complex problems and their solution in a way where anyone can understand.

I used to say the same about the Eve Online dev blog, but at some point I stopped reading because they were creating an ad hoc, informally-specified, bug-ridden, slow implementation of half of Erlang.

Concurrency is hard. Blizzard added progressively more and more concurrency over time to rescue orphaned resources assigned to a single shard that was undersubscribed while another shard in the same AZ was seeing flash mobs. But the way they documented it was more of a tea leaves situation. Only enough data to guess what they had done if you were familiar with the space.
