is there a conventional name for a file that contains the sha256sum of all the other files in the same directory?

here's an interesting way of expressing logic in a rust program:

match statements where the patterns are produced by a local macro.

one of the main problems with rust pattern matching imo is just how large the match statements often are, and local macros fix that.

it's much nicer to write key!('q') instead of Event::Key(KeyEvent{ code: KeyCode::Char($code), .. }

the rust "impl" keywork is kinda weird.

usually, it is used to define methods, but in function arguments, it serves as syntactic sugar so you don't have to name generic types... but in a return type, it has a meaning that is slightly different, and actually expresses a semantic not even vanilla haskell can represent!

basically, instead of being able to return any type implementing a trait, it states that it can return at least one type that implements a trait.

in haskell terminology, specifying a generic type parameter is "forall a", while returning an "impl" is "exists a".

it's not really a question of if unauthorized AI training is copyright infringement, it pretty obviously is, expecially with models that are large enough to just embed a subset of their training data.

the question is if they will reach the same critical mass as video game livestreams, where the backlash of trying to shut it down is too much

the interesting thing about the domain-specific bytecodes of a lot of retro games is they're surprising resilient to segfaults, due to not having a null pointer check.

like, if you found something like the minus world glitch in a modern game, it would almost certainly just crash immediately.

here's a tip if a command is taking a long time and you want a notification when it's done:

^Z fg; notify-send 'done'

pressing Ctrl-Z in a terminal emulator will pause the current running command. running "fg" will resume it in the foreground, but returning to the shell has the added benefit of allowing you to queue up multiple commands in a single line (technically you can do this by blindly typing the command while something else is running (as long as that command doesn't read from stdin), but i think this is more elegant.

notify-send is from libnotify, it allows sending a desktop notification from the command line.

one skill that i don't think is taught enough: given an unfamiliar codebase, how to find the code that handles a specific behavior.

one thing i do a lot in this romhack is go "ok, i want this thing to have effect X", then search the codebase for the name of an existing move/ability that does something similar, since it will probably appear within the function that i want to modify.

frequency can be used to measure things that really feel like they should use different units.

"how often should my OS check the state of the keyboard"

"middle C"

this is technically a coherent answer

the rust attribute syntax was undoubtedly inspired by haskell

it even allows you to enable experimental compiler features like you can do with ghc

linux hardware support is actually like, so insanely good? like i can pull a 10 year old laptop out of the trash and slap the newest 6.7 kernel on it and it runs fine.

you're not getting that from windows, and you're certainly not getting that from apple.

amending tagged commits breaks nix build.

it will keep using the un-amended version
