Lmao so the answer to "why crowdstrike broke" is that they literally have no staging deployment for the cloud based updates, and somebody deployed a thing without testing it at all because the offline content validation said it was fine.

the rental bikes simply predate the scooters, they've existed for a long time. (and having scooters doesn't seem to make the rental bikes stop being a thing either) - also they do have the scooters now.

Do it in zero draw calls! All compute!

for concrete examples: all our hash maps (in internal builds) have a version number used to detect and assert on concurrent writes. when resizing our growing array, we fill the moved-from memory with a specific bit pattern, so it's really obvious in crash dumps when you've invalidated an iterator (but without the overhead of actually tracking iterator invalidation). stuff like that.

i'm sure it's *fine*, but yeah we don't use it at all for the most part. at any decent scale I think the cost of implementing your own datastructures becomes negligible compared to what you can gain from controlling the implementation across all platforms. the easy cases are things like unordered_map where the std version is very not good, but in general it's useful to be able to inject things throughout, profiling hooks, debugging tools, error detection, that kind of thing.
