In Linux everything is XOrCrash, since allocations never fail but the OOM killer can get you later.

This is a great article but it goes into a lot of detail that can be intimidating at first. For me, the reading that made asymmetric fences "click" is this: https://pvk.ca/Blog/201…

Yeah the number sounds a lot less impressive if you say that you only get 2^61.44 integers out of 2^64. In other words, a 4% entropy loss. Information quantities are more meaningfu…

That's a false dichotomy: you optimize both the application and the allocator. A 0.5% improvement may not be a lot to you, but at hyperscaler scale it's well worth staffing a team …

It's not just that zeroing got cheaper, but also we're doing a lot less of it, because jemalloc got much better. If the allocator returns a page to the kernel and then immediately …

RSA was also not given that name by its authors, the name came later, which is usually the case. In the original paper they do not give it any name: https://people.csail.mit.edu/ri…

Here RE2 does not fall back to the NFA, it just resets the Lazy DFA cache and starts growing it again. The latency spikes I was mentioning are due to the cost of destroying the cac…

> are there eviction techniques to guard against this? RE2 resets the cache when it reaches a (configurable) size limit. Which I found out the hard way when I had to debug almost-p…

This is drawing broad conclusions from a specific RW mutex implementation. Other implementations adopt techniques to make the readers scale linearly in the read-mostly case by usin…
