I understood it as compression is 25% better : a quality of 10mbps in av1 can be achieved with 8mbps in Av2.
But, it needs 5 times more compute power for this 25% gain.
The specification for AV2 has only been finalised very recently, so performant encoders have not yet been developed. Meaningful comparison to older codecs like H265 and AV1 will only be possible once that has changed. (It'll be slower, but almost certainly not one-frame-per-second slow.)
dav1d is the av1 decoder and it’s an insane feat of engineering. Written in assembly, it even eschews the normal c calling convention to get even better performance.
The normal C calling convention is really only for cross-binary calls (e.g. between shared libraries). If you're not doing that you can ignore it; it's not a weird thing to do. It would be odd to strictly follow it in assembly and I assume compilers don't either.
Odds of dying in a jet crash are about 1 in 16 million per flight, odds of dying in a mass shooting in the US by living there for one year and doing random things and going random places are within an order of magnitude of that.
I could have said "car" and "driving" instead and it would have been far more likely.

Works OK for small teams. If a user forgets to close the database then other team members are only able to open it as read-only. My biggest gripe is that you don't know who is holding the write lock. We work around this by using a setting in our keepass client to close the db after a certain amount of time.
Plants generally aren't grouped with green algae despite them having evolved from a common ancestor. I guess it's a bit like the crustacean/insect division, so maybe I was being a bit too facetious.
