they're generally pretty but they should really hide the cursor, it looks offputting in basically all cases

"is shared_ptr thread safe?" is a classic question asked thousands of times. the answer by the way is "it's as thread safe as a regular pointer"

atomics aren't free even without contention. the slogan of the language is "you don't pay for what you don't use", and it's really not great that there's no non atomic refcount in the standard. the fact that it is default atomic has also lead people to assume guarantees that it doesn't provide, which was trivially predictable when the standard first introduced it.

maybe some car pool services for the most frequent routes could run at regular intervals. there could even be some predefined stops to efficiently batch many people getting on and off the car pool at once

random example, may or may not come from a real situation that just happened:

    - other team opens jira ticket requesting a new type of encabulator
    - random guy who doesn't know anything of how the current encabulator system works picks up the ticket for whatever reason
    - 10 minutes later opens a 2000 line vibe coded pr with the new encabulator type and plenty of unit tests
    - assigns ticket to the person who designed the current encabulator system for review
    - encabulator system designer finds out about this ticket for the first time this way
    - "wait wtf what is this?  why are we doing any of this?  the current system is completely generic and it takes arbitrary parameters?"
    - waste an hour talking to the guy and to the team that requested this
    - explain they could just use the parameters, close pr and ticket

it's so incredibly productive

tested it on this https://github.com/izabera/cube.bash/tree/timep

i ran `source /path/to/timep.bash; timep ./cube.bash "R U R' U' R' F R2 U' R' U' R U R' F'"`

without profiling https://i.imgur.com/JE93ony.png

with profiling there's a bunch of errors but overall it's ~300x slower https://i.imgur.com/qif7Qp3.png so i'm sceptical on all the efficiency claims

not trying to be a hater but how is 100mb/s high performance in 2025? that's as performant as a 20 years old hdd

I post a lot of silly personal code on GitHub and the vast majority of issues/pull requests I receive are completely inane and generally not remotely helpful. Things ranging from "I've added a subtle shadow effect to the title in the readme" (thought it was someone's first pr just to get started but that wasn't even the case) to "I've added support for $obscure_system_youve_never_heard_of" (well meaning but the code is now 4x longer and a maze of ifdefs so maybe you should just keep it in your branch?) to "I tried this on my extremely outdated system that's old enough to vote and it threw an error" (yes it very much will throw an error, none of this can work there and I cannot help you).

But a few people have reported certain fundamental problems with my approaches or have otherwise put in a significant amount of work to debug and fix issues, and they've been extremely helpful and I can only hope I'll get more of them in the future.

ffmpeg is not too different from a microbenchmark, the whole program is basically just: while (read(buf)) write(transform(buf))

what a "real life application workload" looks like is entirely dependent on your use case, but fio is very widely used in the storage industry

it's a good first approximation to test the cartesian product of

- sequential/random

- reads/writes

- in arbitrary sizes

- with arbitrarily many workers

- with many different backends to perform such i/o including io_uring

and its reporting is solid and thorough

implementing the same for your specific workload is often not trivial at all

this is a hosted lamp stack, we had it 20 years ago. is cpanel is not fashionable anymore?
