you are not proposing a federated amazon, this is just federated ads and/or reviews.

how to process payments? how to ship goods? how to handle refunds? how to handle contestations?

please you can’t just make anything federated. this protocol is built for social media and struggles to take over that sphere, we should focus on one thing rather than throwing random stuff at the wall hoping it sticks (cough federated tik tok cough)

this is an icky issue because lemmy sends votes with empty addressing, so remote instances should count them but not show them to anyone. however mastodon (and *key) sends likes with empty addressing too, but considers them public. lemmy is (surprisingly) right here and should request that the rest of fedi respects the protocol and hides stuff based on its addressing. maybe open issues on mastodon and friendica

also this issue probably exists when seeing lemmy posts on any microblogging instance

your statement is so extreme it gets nonsensical too.

compilers will usually produce higher optimized asm than writing it yourself, but there is room to improve usually. it’s not impossible that deepseek team obtained some performance gains hand-writing some hot sections directly in assembly. llvm must “play it safe” because doesn’t know your use case, you do and can avoid all safety checks (stack canaries, overflow checks) or cleanups (eg, make memory arenas rather than realloc). you can tell LLVM to not do those, but it may happen in the whole binary and not be desirable

claiming c# gets faster than C because of jit is just ridicolous: you need yo compile just in time! the runtime cost of jitting + the resulting code would be faster than something plainly compiled? even if c# could obtain same optimization levels (and it can’t: oop and .net runtime) you still pay the jit cost, which plainly compiled code doesn’t pay. also what are you on with PGO, as if this buzzword suddenly makes everything as fast as C?? the example they give is “devirtualization” of interfaces. seems like C just doesn’t have interfaces and can just do direct calls? how would optimizing up to C level make it faster than C?

you just come off as a bit entitled and captured in MS bullshit claims
