Maybe re-pin the election announcement?

caird coinheringaahing

I don't think we can

at least, it only shows "unpin" for me

Bubbler

It does show "pin this message" for me

caird coinheringaahing

Weird

Bubbler

On first click it apparently unpinned instead of repinning, so I had to do it again and it is now repinned

doubly weird

The question collection thread is due to be posted at any point in the next few days tbh

It's typically posted a week away from the nominations opening, so that'd be the 19th

anyone have other feedback on codegolf.meta.stackexchange.com/a/25092 ? I'm thinking of going with xnor's comment, undecided on pajonk's

Aiden Chow

@att is it allowed for submissions to just graph the function directly instead of asking for input

(I assume no)

Bubbler

Wtf, this code compiles to loopless code

No need to apply mathematics with your own brain

att

@AidenChow it's not graphical-output

user

@Bubbler Is it because usize is finite?

Because I saw a thing involving the Collatz conjecture and the compiler optimized the whole thing away because it held for ints (that was gcc or clang compiling C though)

Bubbler

not sure, it appears to me that the compiler can apply sum(x^2 for x in 1..n) formula

Q: Shorten this dns txt record request script as much as possible

I have made a short script that will pull dns txt records down from a server and combine them into a single string. DNS txt records are: 1.website.com 2.website.com 3.website.com each of these are iterated through using the single digit number. the double quotes at the beginning and the end of th...

@att rip, figured I would ask tho

CMP: Nil type?

emanresu A

Nah

0

PyGamer0

doesn't really replace nil

for example FindIndexOf([1,2,3],4) → 0

whereas FindIndexOf([1,2,3],4) → Nil

i could use []

but what if this happens AllEqualsReturn([[], [], []]) → []

(k also has nil types)

emanresu A

Nil types are bizarre and rarely make sense

@PyGamer0 -1

PyGamer0

i will just keep it [] for now

@Neil Thanks, I know what a page fault is. However, in this case you should get only 2 page faults right? One for loading the program and one for accessing the memory the program is using for the first time

Neil

8:33 AM

@mousetail you'll at least get a fault for each page of the program including all of the linked libraries and shared objects that are needed for it to run

note that you get a page fault for a shared library even though it's in memory; it's just not in your memory yet

mousetail

@Neil A empty program shouldn't require that many shared libaries right? Maybe like 10-20

Neil

I really have no idea

mousetail

Do you know a convenient way to measure page faults offline?

pxeger

10:00 AM

@mousetail ATO's measurement will also include the page faults of the compiler and a few intermediate wrapper processes used by ATO

mousetail

@pxeger I get that. I wouldn't have cared about page faults at all if it hadn't been shown but now that I see it I'm wondering what a accurate measurement would look like

pxeger

@mousetail ato.pxeger.com/…

ATO is no match against TIO

looks like it won't even output "hello world

even if you write main(){printf("hello world");}

TIO atleast prints it

mousetail

10:41 AM

@py3programmer ATO prints it?

mousetail

10:52 AM

this is more like it: ato.pxeger.com/…

pxeger

11:31 AM

@py3programmer What?

user

11:52 AM

@py3programmer sounds like a you problem lol

Maybe it’s just taking longer to execute

mousetail

Hello world prints instantly though

Maybe the runner was down for a moment

emanresu A

ATO is kinda sus sometimes

~~use DSO~~

mousetail

The frontend is super nice though

I'd like ATO's frontend with DSOs backend

py3programmer

guess something was wrong with my laptop

emanresu A

"backend"

py3programmer

11:57 AM

now its printing

mousetail

Code running system

emanresu A

It's just browser JS / a python venv

mousetail

Oh really?

That explains the weird language selection

emanresu A

Pretty much - I use pyodide.org for the python stuff and I occasionally find motivation to fiddle with wasm and other stuff

In theory porting v86's lua / ruby should be possible for example

mousetail

did it use to have a backend? I thought I remember some talk about streaming logs over websockets but that might have been another tool

emanresu A

12:00 PM

That's probably ATO. It's never had a backend, from the start the whole premise was broswer-based stuff

Also that my wrapper files would load interpreters from source for easy autoupdate

mousetail

That's cool

My CellTail online interpreter works like that too

emanresu A

rust to wasm?

mousetail

Yea

Built in a github action

emanresu A

steals

mousetail

Feel free to steal my code

emanresu A

12:03 PM

Bubbler has TIB which operates on a similar premise

@mousetail It's probably more readable than ngn/k or rustpython lol

ngn/k is hand-golfed and does some weird allocation stuff, rustpython is fricking webpacked

mousetail

Damn you are going to run out of 3 letter acronyms soon if everyone builds a online runner tool

py3programmer

true

@mousetail RTO (had/has/was going to have) that I think

mousetail

@pxeger That could be it. In that case I'd like to see RTO's backend with ATO's frontend

pxeger

I am currently rewriting ATO's backend so hopefully you'll like it more soon lol

I'm sure it will start off more buggy but hopefully quickly become less buggy than the old one

mousetail

Like there is nothing wrong with your backend, it's just I vagely remember RTO having some cool features. I don't remember what they where though

@pxeger What are you rewriting it in?

pxeger

@mousetail Streaming I/O was one of them, and ATO's new backend should make it easier to add that

Rust

mousetail

Cool cool

pxeger

12:34 PM

Previously a mishmash of Go, C, Zsh, and Bash

There's nothing particularly wrong with any of those, but I chose each as the "right tool for the job" and it's much nicer to have one tool which is right for all the jobs

mousetail

Need any help? I'm looking for something to practice some rust with

pxeger

@mousetail Sorry, I'm doing perfectly fine at the moment ;)
