Very cool

@hyper-neutrino It's Arnauld's answer but Jellified :P

@lyxal yep, it's tomorrow

(in UTC)

hyper-neutrino

i can't think of a good way to do this is vyxal immediately

no "repeat until non-unique" built-in

wait the number of bits in X is always <= X. i could probably use this

Q: Sum on a Fenwick Tree

It's not a typo

@NewMainPosts I was getting worried about you. Wondering if you'd gotten diabetes or something

glad to see you're back

lyxal

@hyper-neutrino if I use single quotes, it messes up the description hoverboxes on the keyboard

hyper-neutrino

...

then just say "does not"

@lyxal wrong

Redwolf Programs

We're ignoring the obvious solution

doesNt

hyper-neutrino

0⁽⌐Ẋ doesn't terminate

lyxal

How about ↔ then?

hyper-neutrino

00:08

this should work for this challenge

but repeat until non-unique is different from repeat until invariant/idempotent

lyxal

Ighto

One built-in for non uniqueness coming up

hyper-neutrino

pog

this one will work for this challenge if anyone wants to solve it tho

caird coinheringaahing

Just do while non-zero instead

hyper-neutrino

no worries! I just answered it earlier today, lol

i just searched by "asterisks" and sorted by votes

caird coinheringaahing

Bruh, just go to your user page

LorenDB

caird coinheringaahing

01:55

Sorting your posts by newest (the default IIRC), it's the second one there :P

hyper-neutrino

@cairdcoinheringaahing shhhhh i only remembered that after i searched

also it's my first answer sorting by newest which makes it even easier to find

but then i need to share the question or remove the answer ID from the link

caird coinheringaahing

It's also pretty high up on the Active Questions page :P (10th)

Make that 1st :p

LorenDB

Obviously I didn't look very hard :D

hyper-neutrino

new posts fetched my yuno answer

my userscript may be out of date

LorenDB

Changing the subject: how could I go about getting Barrel into TIO? Do I just need to talk to Dennis or can I PR the TIO repo or is there something else I need to do?

hyper-neutrino

02:02

@LorenDB unfortunately all you can really do for now is ask caird to add it to the update/request list for TIO. dennis hasn't updated TIO in a while and we have no time estimate for when he will return (you can see more about that in the TIO chat room itself)

caird coinheringaahing

in talk.tryitonline.net, Jan 26 at 10:06, by caird coinheringaahing

@Nirvana Currently, in order to update a language on TIO, Dennis has to update the version of the language stored and used by TIO (slang term "pull"). As the owner/maintainer, only Dennis has the power to do so. From my understanding, Dennis was working on creating user accounts for TIO so that if you were registered as a language developer, you'd be able to "pull" your language by yourself without having to go through Dennis. I have no idea how far along that idea is though

Dennis, unfortunately, is (as HN said, and can be found in the chat room) not maintaining TIO, however

hyper-neutrino

i wonder if it'd be worth to launch a community initiative to reboot dennis' TIO (or create a new version, maybe like pxeger's ATO or something) to a) take the load totally off of dennis' mind, and b) maintain it across more people for faster changes / updates and less work for each person or w/e

LorenDB

All right @cairdcoinheringaahing, the ball's in your court now

caird coinheringaahing

TIO is entirely open source, if someone wants to host it, they can. Additionally, I'm pretty sure Dyalog (Correct me if I'm wrong @Adám) has offered to help pay for the costs of the servers

@LorenDB Do you have a repo link for Barrel?

hyper-neutrino

it's definitely possible. i'm not sure i know how but i could give it a shot at booting it up

my laptop should have enough memory and be able to run more or less permanently (my server is too small i think)

just to like test it out

caird coinheringaahing

02:05

If I knew anything about Linux, I'd give it a go :/

LorenDB

@cairdcoinheringaahing Yeah, github.com/LorenDB/barrel

caird coinheringaahing

@LorenDB Updated the list of requests

hyper-neutrino

even if i can just pull all of the new requests and updates into a fork and PR that maybe Dennis would be able to update that, if he's still watching the room and feeling well enough to do that

though, that might introduce bugs, and it's better than TIO remains stable, even if outdated

caird coinheringaahing

@hyper-neutrino I have a hunch/belief that Dennis is still watching the chat room. If you click on his pfp, the "seen" value is very rarely in minutes, and every time someone notices a major bug (i.e. preventing a language from running, bug in TIO as a whole etc.) it gets fixed pretty quickly

hyper-neutrino

Yeah, I do think (and hope) he still is. I do remember once the whole thing seemed to be freezing/not working and I mentioned it and he fixed it really fast.

caird coinheringaahing

02:09

Opening a PR that is able to just be integrated into TIO with a single click (no major bugs, etc.) would probably be the best way to get updates to TIO

hyper-neutrino

the thing is TIO is actually coded properly and not just a shitty flask server you can run with one command like my interpreter

so it actually takes brain cells to figure out how to launch it. you can run my interpreter by just cloning it and doing python3 server.py or smth

caird coinheringaahing

@cairdcoinheringaahing I should probably follow Journeyman's suggestion and rework it as a feature-request, but it's past 3am here, so I think I'll do it in the morning :) See y'all o/

Redwolf Programs

02:35

I'm fairly experienced with Linux and have some practice running servers, and know a bit about front end web development. I don't think I have the time to run a TIO clone (or make my own), but I'd 100% be willing to contribute to any efforts to set something up if needed.

Testing on Godbolt reveals that each function compiles to a plain function, and a constant expression using ! explicitly calls the compiled code for ! (even with optimizations turned on). The code is definitely not computing those at compile time. — Bubbler 33 secs ago
