tl;dr:
manage process resource limits

i wasn't gonna include the prlimit one in this thread, but the manpage grouped them all together, so i figured i would include it too.
lots of bugs in the history of these syscalls. i guess it's a relatively complicated system.
the concept of soft limits and hard limits is pretty interesting. it makes me curious as to the history behind this design decision. i'm sure someone out there knows it. maybe that one anon who posts a lot of cool history tidbits?
which resource do you most often find yourself modifying, anon? some are definitely going to be a lot more common than others, but i'm curious to hear what you all have to say

I'm getting the vibe that there's a syscall bloat problem... We need a simplification with an optional translation layer.

uwah!
>>108407942
if you want to know the truth, i generally just search my gallery for a relevant word, and then pick the image that comes up which i like the most
so for example this time i searched "limit" and that was one of the images that came up
there are some other good ones, e.g.

syscall autist anon, that's just a funny pic you chose for OP, right? You're doing just fine and dandy? Because I dunno if you get the appreciation you need for your particular kind of autismo bightening up the catalog amidst the shilling wars and aisloppa generals.

There are only two codes I can imagine hitting this limit and one of them is isEven.

I think the only limits that regularly trip me up with cryptic error messages every other year are the user process limit, file descriptor count and coredump size.

>>108409101
what tool are you using to find images via ai/multimodal models? I'm aware that you can use something like CLIP to generate embeddings and then do a distance search to find similar things but I haven't really looked too much into it if there's some simple existing solutions that can handle a lot of files somewhat efficiently.

This is why retards shouldn't be allowed near kernel interfaces. We'll be paying the price of these for centuries, and all because one tard once thought

aww, thanks for the concern anon. that's really sweet of you. i'm doing pretty well these days, all things considered. it's always really nice to hear from people who appreciate my threads, though. i worry sometimes that i am wasting my time making them, so replies like yours mean a lot to me

i just use samsung's stock gallery app lol. a few years back they added some fuzzy search tool, and it works decently well (certainly isn't perfect, though). but it's good for stuff like this
