The Nineteenth Byte

CMM: Could TNB do with a couple more room owners? On the one hand, most of the current ROs are inactive. On the other hand, we can usually get in contact with a mod fairly easily, and we don't have too many issues that require an RO anymore (e.g. star spam). Thoughts?

Has there actually been any time when someone asked a room owner to do something and all ROs and mods were inactive.

Bubbler

Even if there were none recently, it's good to have one who can handle it, just in case (I guess)

@pppery Off the top of my head, not that I can remember. But IMO it wouldn't hurt to appoint a couple of high-rep chat-active users as ROs just in case

i should make a language specifically to solve AOC problems

maybe a project for next year

and what may that be

I got 0 for my answer and I tried submitting it

my mistake was returning ip

bruh how to do part 2

nice. big brain

@Lyxal brute force

@Lyxal my favorite tool, total brute force

ASCII-only

5:13 AM

im like

pppery

Yep, I also used brute force

ASCII-only

yea for aoc brute force is usually the easiest way (c.f. day 1)

Unrelated String

it has to be a problem specifically constructed for that purpose for brute force to be prohibitively slow

Redwolf Programs

I made a stupid mistake on part one, mistyped a 1 instead of a 0

ASCII-only

i wanna see everyone else's solutions

bc i always absolutely butcher mine

5:17 AM

@HyperNeutrino I'm making a language that transpiles to JS for solving AOC, it slows me down a bunch but it's fun :p

HyperNeutrino

ooh, sounds cool :D

ASCII-only

@RedwolfPrograms why not use my lowquality lib

pppery

Whoops, I realized my part 2 had a typo that would make it give me the wrong answer 50% of the time and apparently got lucky.

HyperNeutrino

i'm thinking of hyper-optimizing some quickly codeable thing with like ez regex input matching and common math/array manipulation things for speed coding

ASCII-only

bruh

HyperNeutrino

5:18 AM

wow nice :P

ASCII-only

@HyperNeutrino it's called github.com/Aplet123/iterplus

Redwolf Programs

The problem is I can type my solutions way faster now, so I don't end up thinking through them enough :p

lol

i need to get on making my aoclang

smh everyone making langs

just use cjam.

Lyxal

No lol

ASCII-only

aka "google code jam lang"

Unrelated String

5:21 AM

is that actually the story behind cjam

ASCII-only

probably.

Redwolf Programs

lol

Unrelated String

~~and the best they could come up with was extended golfscript~~

ASCII-only

@UnrelatedString if you mean backwards pyth, yes

Lyxal

What's the probability that this lang will be featured more than once?

ASCII-only

5:22 AM

negative.

pppery

Unlikely

It's not like we'll see this poor kid ever again once the plane lands

Redwolf Programs

Not really much you can do with it anyway, unless they just decide to teach us x86 assembly with some different syntax

Lyxal

So no esolangs page like last year?

Unrelated String

i'd hope not

this lang was basically just shitty assembly

Lyxal

Intcode kinda was too until they added stuff

ASCII-only

5:25 AM

with three instructions

and no branching so it's not turing complete

Lyxal

Welp, back to learning Jelly and playing Minecraft I go

Bubbler

5:57 AM

F*** assembly again

5233/6032

Took an entire hour to finish

Maybe I should just have written a while loop instead of a sophisticated recursive function, which tripped me A LOT of times with stack effects here and there :/

Unrelated String

yeah

Q: Generating versions of an array with elements changed in ruby

I'm new to code golf challenges. My problem came up in Advent of Code 20202 Day 8 The input is an array of arrays.

Okay wow I only just understood Leaky Nun's username with some help from the way back machine

here's the explanation (scroll down for a bit)

Oliver Ni

Anyone wanna help me golf something down

I think I got it as down as I possibly could but

Lyxal

What language?

Oliver Ni

Python

(lambda f,z:print(-f(z,f),max(f(z[:i]+[("njompp"["nop"in z[i]::2],z[i][1])]+z[i+1:],f)for i in range(len(z)))))(lambda x,f,i=0,a=0,s=[]:a if i>=len(x)else-a if i in s else f(x,f,i+(1,int((t:=x[i])[1]))["jmp"in t],a+("acc"in t)*int(t[1]),s+[i]),[*map(str.split,open("i"))])

The challenge is here adventofcode.com/2020/day/8

Bubbler

Paste code and Ctrl+K

Maybe change for i in range(len(z)) to for i,v in enumerate(z)? I think it'll save some bytes as you have references to z[i]

Oliver Ni

Oh that did save 5 bytes

@Lyxal I remember when he changed name. But you probably don't know why he chose exactly that anagram.

Lyxal

10:04 AM

Do tell me exactly why.

Adám

Kenny visited me at home (yes, IRL) a couple of times, and I think I figured out why he chose that name, but it'd be a private matter and not for me to discuss here without his approval.

Lyxal

10:30 AM

Oh okay I thought you meant the exact reason was something public on CGCC rather than personal

@2x-1 What is that about? it has no description.

maybe it could be "this is for the fun & silly conversations had in The Tarpit that might get in the way of on-topic conversations"

Can anyone find a way to make this output any specific value? (or just one specific funny value?) it looks like it'll involve solving equations with modulo in them, which I don't know how to do

Q: For what block sizes is this checksum valid?

The input: As an example, take a list containing a number of bits (in this case, 32): 11000010000100111011000011001011 We can calculate a simple checksum of this data by dividing it into evenly sized blocks, and taking the XOR of each of them. For example, with eight bit blocks: 11000010 0001001...
