@cairdcoinheringaahing well yes but actually no

Still 19 hours to go - that's 6am tomorrow for me

How about a classic snake koth, with two bots racing against each other on two separate boards?

mousetail

One board is more interesting

thejonymyster

one board reminds me of the light bike tron one, but whats the strategy in two boards?

mathcat

yeah, but it already exists :(

mousetail

I've won at that exact KOTH before so I'm all for but since the competition was all first year CS students it was pretty easy

most snakes where actively suicidal

thejonymyster

lol maybe misere snake then

mousetail

12:42

Then you could just turn left 4 times and lose right? Not much creativity needed

thejonymyster

hm

some kind of snake chicken, where you wanna go as long as possible while still dying first?

idk :P

mousetail

Might be interesting

not sure how a chicken KOTH would work

Question: For the election, how many are "not enough" eligible candidates?

pxeger

Fewer than the number of positions available to elect to?

mousetail

So less than 1 in this case

@Catija can you confirm?

thejonymyster

1 per person

Seggan

13:26

yeah

mousetail

@mathcat Manjaro

Seggan

even better, 2 per person

seriously, Debian

mathcat

I'm thinking of using a WSL

mousetail

In WSL it doesn't really matter at all, it works mostly the same. Systemd is nice to have but I think all distros except debian have it now

Seggan

13:32

whats systemd

i only ever used debian

mousetail

way to manage background tasks, like docker, servers, databases etc.

debian has another system but I find systemd more convenient, and more services support it natively so often you don't even need to touch it

Background tasks as things that should always be on, not like things running in the background that you expect to complete

Seggan

Systemd

systemd is a software suite that provides an array of system components for Linux operating systems. Its main aim is to unify service configuration and behavior across Linux distributions; Its primary component is a "system and service manager"—an init system used to bootstrap user space and manage user processes. It also provides replacements for various daemons and utilities, including device management, login management, network connection management, and event logging. The name systemd adheres to the Unix convention of naming daemons by appending the letter d. It also plays on the term "System...

mousetail

oh nice, I guess debian is fine then

I used a different tool on ubuntu on a old computer which was pain before but that was a while ago maybe it changed or maybe ubuntu is different from plain debian

@mathcat arch. linux.

@mathcat why

mathcat

That way I get clean GUI + a good terminal

PyGamer0

@mathcat am i the only one who thinks linux has a good gui :p

mousetail

Linux does have a good gui though, you just need to customize it a ton before it looks ok

PyGamer0

i like customization, i spent 1½ years customising (neo)vim :P

mousetail

Then linux guis are for you

there's a subreddit for pinped linux desktops

I forget what it was called

pxeger

Linux does not have a good gui

Linux does not have a gui

mousetail

There are good guis available for linux

pxeger

And there are bad guis available for linux

mousetail

yes

pxeger

I happen to use a good one

PyGamer0

@pxeger oh

mousetail

14:44

that's the cost of customizability

PyGamer0

@pxeger which one?

pxeger

@PyGamer0 Hannah Montana Linux

mousetail

The best one

pxeger

though I want to switch to the keyboard one someday

PyGamer0

@pxeger lmao why does that exist

pxeger

(but similarly, you can make KDE both good and bad)

PyGamer0

@pxeger Killer Desktop Environment?

I think it's just "K Desktop Environment"

K is just the letter K

i wish making fonts was easier

PyGamer0

@pxeger ~~ahhh it's named after Arthur's k~~

mousetail

14:47

I'm just a big fan of trolling my coworkers by making my screen as ugly as possible. I used to have everything in purple and pink but eventually I wanted to go back to being able to read

PyGamer0

@mousetail reminds me of my attempt at making a Minecraft font link

mousetail

@PyGamer0 what does it look like?

PyGamer0

looks like the minecraft font but i messed the spacing so its wider

@mousetail check mathcat's game tams-tams.itch.io/gravitruttle

pxeger

@mousetail You seem to be using the default KDE clock/calendar. May I introduce you to Event Calendar

If you like customisation, this is what you want

Seggan

is there any function that maps an input to a random unique output given a seed?

by unique i mean no other input will have that output and the output will change only if the seed changes

thejonymyster

15:01

what's the random part then

Seggan

the seed

nvm misread

the mapping input -> output

lemme eat then ill answer ur questions

thejonymyster

ah i get what youre saying now though

thejonymyster

15:25

i suppose youd have to give it your list of possible inputs and list of possible outputs as part of either the seed or the input?

like, domain and range for the mapping

or at least a type :p

and then i guess a mapping of seeds to functions/permutations? i wonder if there are any languages in which this is really easy to implement cause of builtins lol

@mathcat Fedora, 100%

You've got almost as good of support as Ubuntu, since there's Fedora, CentOS, and Red Hat that are all pretty similar, it's easy to use, much more than Arch IME.

I've only ever used server distros of it tho

Seggan

@thejonymyster yeah the inputs/outputs are hardcoded

only thing i can think of is reconstructing the mapping every time the function is invoked using the good old "choose random from list and remove it" trick

fun f(in, seed) {
  mapping = {}
  for (input in inputs) {
    output = random.choose(seed, outputs)
    mapping[input] = output
    outputs.remove(output)
  }
  return mapping[in]
}

And of course, not two hours after I accept the job offer, I get a call from a different place I'd applied to, about setting up an interview. After six months of not getting an interview anywhere. Nice :|

Wheat Wizard

@RadvylfPrograms My deepest condolences.

caird coinheringaahing

@RadvylfPrograms That's great, you get to say no to them with no consequences :P

Radvylf Programs

Yeah, except this place would've paid $18/hour :p

@RadvylfPrograms good luck ;_;

Radvylf Programs

Yeah, but this one's not too much worse of pay, and it's closer.

Seggan

@RadvylfPrograms noice

what job?

Radvylf Programs

Grocery store

Seggan

as what? (hope you dont mind me asking)

thejonymyster

as the groceries

mousetail

Or as the store?

Radvylf Programs

17:20

@Seggan I am the store itself

mousetail

Cool, can I please have 2 tons of groceries then?

Radvylf Programs

(I'm just going to be the guy who scans the things when you buy them)

thejonymyster

@RadvylfPrograms do you also make the beep sound? if so, can you change it to the lyxal's fridge sound?

Radvylf Programs

Yeah, it's the person's job to make the noise. It takes weeks to get it just right. If we don't make the noise we get fired and sued by the company for millions, so I can't make the fridge noise.

LDQ: should the "list of divisors" builtin include itself

Radvylf Programs

17:31

Ash had two divisors built-ins

One didn't include 1 or the number itself or duplicates

And one did include 1 and itself, and it included duplicates

Seggan

well fig doesnt have too much codepage space

Radvylf Programs

So for example, 9 would be 3 with the first one and 1 3 3 9 with the second

@Seggan Oh yeah this is for fig

Hmm

Do you include 1?

Seggan

ye

Radvylf Programs

I can see advantages of both, so I'm not sure

The idea behind Ash's second one was that the second half of the list is the first reversed, and un-divded by the input

Which might be a useful property, or might not, idk

I think Jelly excludes the number itself, and Jelly tends to make good life choices

DLosc

@Seggan Do you want the result for 1 to be [1] or []?

Seggan

17:46

rn its []

idc tbh

@RadvylfPrograms hmm jelly has no factorization builtin?

wait do we not have a normal factorization challenge

Radvylf Programs

Q: Find the positive divisors!

Definition A number is positive if it is greater than zero. A number (A) is the divisor of another number (B) if A can divide B with no remainder. For example, 2 is a divisor of 6 because 2 can divide 6 with no remainder. Goal Your task is to write a program/function that takes a positive number ...

Did y'all make an event manually or are we being a bit... effusive with the events?

Ginger

who knows, they just seem to magically appear q:

thejonymyster

@Catija i just googled "effusive", i have no idea what youre asking, but its probably cause im stutupid

Ginger

20:26

verbose, I think

Catija

@Ginger Ah. Yeah. Huh - did not realize that effusive was limited to emotion... Hmmm. collinsdictionary.com/us/dictionary/english/effusive the AmE definition seems to be how I use it.

Ginger

alternately: relating to the eruption of large volumes of molten rock

Seems reasonable - if words == rocks :P

CMC: Come up with an actual challenge using those tags :P

emanresu A

LMAO at deadfish

probability-theory is the odd one out

The rest is some sort of deadfish metagolfer

Wheat Wizard

@emanresuA Are metagolfers really open ended?

emanresu A

I'd say yes, you can output anything you want as long as it's valid by the criteria of doing the requested thing

Wheat Wizard

In that case optimized-output is a subtag of open-ended-function

And I don't really feel like that makes sense.

emanresu A

22:03

¯\_(ツ)_/¯

DLosc

@WheatWizard Given a string S and a number N, return a Deadfish program that outputs a string whose Levenshtein distance from S is at most N.

/hj

Wheat Wizard

... exactly 50% of the time.

Unrelated String

22:23

@WheatWizard yeah, i feel like there's a pretty big difference between open-ended-function bearing on a validity criterion versus metagolf/optimized-output bearing on a scoring criterion

in both cases the exact output for any given input isn't specified, but the variation in outputs is fundamentally different

although i guess metagolf also bundles a validity criterion in there with it, you still don't have any variation in the output that's motivated by factors internal to the solution itself, because nothing about the solution as code is being scored
