<rlb>...how have I not been using ${x@Q} all the time in bash? (Have to see what version added it.)

<rlb>So much more convenient than printf %q in some cases.

<dsmith>ACTION looks at the bash man page....

<bremner>ACTION waves at some familiar faces

<bremner>is there a published statement about LLM generated contributions to Guile? I didn't see one in a cursory look at the web site.

<Alavi_me>Hi

<Alavi_me>I'm searching about janet and guile, They both seem to have the same purpose and philosophy. Janet is more clojure-y and more batteries included. But what are the main differences and pros/cons in you guys' opinion? I can't find much online.

<ekaitz>hi! can I force guile to be single threaded?

<ekaitz>i mean, i want it to only use the 100% of my CPU, not more

<identity>ekaitz: i would guess you can set NPROC RLIMIT to 1

<ekaitz>i don't know what that is

<identity>as in setrlimit(2)

<ekaitz>thanks! i'll read about it

<old>ekaitz: use taskset(1)

<ekaitz>i'll read that too (i've never done this before)

<ekaitz>old: reading through it... I don't want guile to run in an specific processor but just using one

<identity>ekaitz: if you allow it to run only on e.g. CPU 1, it should not be able to use more than 100% CPU, as it is only allowed to run on one (specific) core

<ekaitz>identity: yes, but it wouldn't change the CPU, and any normal single-threaded long-running process would

<ekaitz>i mean, it's not the "natural" environment

<ekaitz>(i'm doing this whole thing as a performance comparison to GNU Mes)

<bremner>ekaitz: depending on your OS, you may want to look at cgroups

<rlb>bremner: hmm, I don't know of any right now.

<rlb>I'm not sure I knew this. If you want guile to pick up ../foo.go for the invocation "guile ../foo.scm", it's "guile -C . ../foo.scm" not "guile -C .. ../foo.scm", and it won't find it otherwise.

<rlb>But default, I'd expected "guile ../foo.scm" to look for foo.scm.go in the path, not ../foo.scm.go...

<rlb>"By default"

<rlb>Is there a way to invoke ",time x" as a function from a script?

<rlb>nvm, I just copied and adapted the code, though seems like it might be a nice utility function to have someday.

<old>ekaitz: on linux what you want is probably mm_cid then

<old>idk if it's available as of right now, but you can limit the concurrency of a memory mapping process to a number

<old>so no more than X threads in your process can run in parallel, without touching the CPU masks

<ekaitz>i don't know what that is either

<ekaitz>haha

<old>it's part of the RSEQ system call and is ABI between the kernel and userspace. But you probably need a recent glibc to handle that

<old>so your best bet is to use cgroup

<old>and limit the load of your process

<ekaitz>old: i was looking for a way to just call guile --jobs=1 or something so I could test the single thread performance
