This is a new program that got announced today: https://www.ea.com/news/introducing-ea-advertising. For reference, EA's FC26, one of the games that they're advertising in-game product placement opportunities for, costs 70 dollars.

For this use-case, you can squeeze out even more performance by using the SHA-1 implementation in Intel ISA-L Crypto [1]. The SHA-1 implementation there allows for multi-buffer hashes, giving you the ability to calculate the hashes for multiple chunks in parallel on a single core. Given that that is basically your usecase, it might be worth considering. I doubt it'll provide much speedup if you're already I/O bound here though.

For those that thought the process of speeding up CRC was interesting, I strongly recommend reading [1]. It describes a step by step process on how a naive CRC implementation might be improved, until finally arriving at an implementation in assembly with a staggering throughput of 62 processed bits (almost 8 bytes) per CPU cycle. Yes, you read that right.

Their Rust game is currently in closed alpha: https://wim.live/en/.
Last time I tried it, they were working on integrating wasm support for user-accessible custom scriptable scenarios (a la Roblox).

If compiled with -O3 on clang, the loop is entirely optimized out: https://godbolt.org/z/M1rMY6qM9. Probably not the fairest comparison.

Time and time again we learn that people do stupid things under stress. Consider Transair flight 810 [1], in which a simple engine failure during takeoff results in a complete loss of the aircraft when both pilots mistakenly identify the _wrong_ engine as malfunctioning, despite identifying the failure correctly only minutes earlier. OP has an article on that crash too, actually [2].

OP also has an article on Helios 522, for those interested: https://admiralcloudberg.medium.com/lost-souls-of-grammatiko...

The same author as the OP also has a great article on Helios 522: https://admiralcloudberg.medium.com/lost-souls-of-grammatiko...

If you liked this article, definitely consider checking out other articles written by Kyra (Admiral_Cloudberg). She has done a ton of articles on almost all notable (near)crashes, including their root causes, investigations, and subsequent effects on the airplane industry.
For some crashes that have interesting causes (at least from an engineering perspective) beyond "maintenance failed to identify a problem before takeoff" or "pilots fail to identify problem or take wrong actions", I strongly recommend the articles on TWA 800 (1996) [1] and the near-crash of SmartLynx Estonia 9001 (2018) [2]. The first goes into great detail exactly _how_ the FAA discovered the root cause, whereas the second one involves a logic oversight in the flight computers of a modern Airbus plane.
