The Nineteenth Byte

haha american nerds doing it at like midnight

hyper-neutrino

i'm still conflicted on if I want to use a library for python / my solver or just vanilla python

on one hand i am aiming to get as high of a score as I can but on the other hand it lowkey feels like cheating :p

Redwolf Programs

My JS library is going to basically completely overhaul the language, so it feels less like cheating because I basically wrote my own language lol

lyxal

I wonder how well codex will do for aoc

hyper-neutrino

my "solver" is really just a super scuffed lisp heavily based around step-by-step processing with the REPL lmao

but given how limited it is and the fact that i'm too busy to write enough utility to make it useful by dec 1st i'll probably just stick to vanilla python

Redwolf Programs

I'd use vanilla JS if it wasn't total frick

Thomas Ward

23:10

lol python... rare to see a CGCC person say they'll use vanilla python

@hyper-neutrino who are you and what did you do with the REAL hyper-neutrino?

hyper-neutrino

@ThomasWard wait wut

i love python tho

ok that's a lie it's the only language i kinda tolerate tho

Thomas Ward

lol as i said who are you and what did you do with the real HN?

hyper-neutrino

is the real HN supposed to dislike python o.O

well crap my cover's been blown

caird coinheringaahing

@ThomasWard I use vanilla python :P

Thomas Ward

lol

caird coinheringaahing

23:12

But only because I suspect my course won't let me use Jelly instead :P

Thomas Ward

lol accurate xD

caird coinheringaahing

Actually tempted to ask, just for the shits and giggles :P

Redwolf Programs

Python + jelly is the only programming language that is perfect

hyper-neutrino

pretty much all the personal project code i've written in the past like couple years has been python lol. jelly and vyxal for golfing and racket, C, and C++ for class, but python otherwise

Thomas Ward

@hyper-neutrino python for most of the stuff I do, minor Bash scripting for some quick admin scripts.

... which reminds me i need to finish my aiosmtp based replacement for the workplace home-grown IMAP-driven listserv solution xD

lyxal

23:14

Nothing wrong with using snakes for the purpose of computational processing :p

on a different note, someone's made a userscript/browser extension that brings back the dislike button on YouTube

Unrelated String

lol

caird coinheringaahing

bruh just use the app

Unrelated String

is it an api call or did they forget to actually remove the data from the page itself

caird coinheringaahing

It has to be an api call, cause the app still shows exact numbers

Thomas Ward

@lyxal true, or for dissecting email messages and doing stuff with them

like listservs need to work xD

caird coinheringaahing

23:20

("exact" if low, but still numbers)

lyxal

@cairdcoinheringaahing it is

Apparently it's still working

Thomas Ward

combine asynchronous processing and redis driven workers for actually processing individual messages and BAM things work great and nmake listservs much more functional than waiting on a never-cleaned IMAP inbox to respond to commands xD

hyper-neutrino

@lyxal ah did you see that on truttle's server as well

just saw the ping for it

Thomas Ward

@hyper-neutrino not gonna lie, Python sucks for golfing, but for pure easy readability, ease of learning, and expandability and flexibility for different tasks you can do on it, Python's a pretty good language

that and most linux distros ship it xD

lyxal

@hyper-neutrino lol yes

hyper-neutrino

23:22

@ThomasWard that's true. but TBH these days i do more non-golf coding than golf coding

but yeah python isn't great for golfing; i usually just use jelly

Thomas Ward

@hyper-neutrino yeah that's me too. i will admit though that i had to take a lot of time to learn how aiosmtp and its constructors work recently

THAT was pain xD

mainly 'cause i had to build a StartTLS compatible constructor for it heh

caird coinheringaahing

@ThomasWard As someone who only really codes for fun, you could've just shuffled the dictionary, chosen some words and put them together, and I'd believe that was something tech-y that you probably do/did :P

Thomas Ward

lol

hyper-neutrino

as someone who is in CS for my degree, same

Leaky Nun

CMC: Given positive integer n, determine if n*n and n have the same units digit

Thomas Ward

23:39

@hyper-neutrino using pure C, build an email listserv system. :P

shows self out

Adám

@LeakyNun APL: 10=.|⊢,×⍨

lyxal

@LeakyNun Vyxal, 5 bytes: e"vt≈

Or Try it Online! for multiplication

hyper-neutrino

@LeakyNun Vyxal, 4 bytes: 5%1≤ (Try It Online!)

lyxal

(because I totally didn't accidentally read it as n^n not n^2)

Leaky Nun

@hyper-neutrino cheeky

hyper-neutrino

23:44

:)

lyxal

@hyper-neutrino w....h...how?

How tf does that work

hyper-neutrino

units digit of product only cares about units digit of factors

the working units digits are 0, 1, 5, 6

you get units digit by doing % 10

and then units digit % 5 must be 0 or 1

but %10 %5 is just %5 because 5|10

therefore %5 <= 1

you can do it in jelly for shorter with %5Ị

Adám

So that's 1≥5| in dzaima/APL with a trailing ⊢ in other APLs.

hyper-neutrino

oh you need a trailing ⊢

that's why i couldn't get it working

i wanted to outgolf adam in apl first :p

Thomas Ward

@hyper-neutrino never going to happen xD

hyper-neutrino

23:46

:(

Thomas Ward

'course if it does that means the Codepocalypse is happening so we're all doomed

lyxal

I'd take that over code golf contests on sites which score every language (even the ones with SBCS) as utf8

hyper-neutrino

vyxal has a %5 built-in but it's a shame it checks ==0 ~~because fizzbuzz overspecialization smh~~

lyxal

Shh don't say that.

We're focusing on more generalised overspecialisation, remember? /s

in Vyxal, Oct 31 at 13:01, by lyxal

yeah I figured that we should stop overspecialising for just fizzbuzz, and start overspecialising for more challenges :p (that's a joke please don't quote this out of context lol)

Leaky Nun

CMC: Given a positive integer, return the alternating sum of the digits starting from the units digit. e.g. 43134 -> 4-3+1-3+4 = 3

hyper-neutrino

23:51

starting from units digit as in 1234 becomes -1 + 2 - 3 + 4?

Redwolf Programs

@LeakyNun Using a palindromic number seems like the worst possible test case choice lol

hyper-neutrino

^

caird coinheringaahing

What's the LYAL this time?

Unrelated String

^

Leaky Nun

@hyper-neutrino yeah

lyxal

23:52

@LeakyNun can we take input as a list of digits?

Leaky Nun

sure

caird coinheringaahing

Zsh, Stack Cats and Lost are the top voted

Redwolf Programs

@LeakyNun f=x=>x&&x%10-f(x/10|0)

Alan Bagel

def altsum(num):
sign = 1
s = str(num)
total = 0

for i in s:
total += int(i) * sign
sign = -sign

return total

(not golfed)

hyper-neutrino

ctrl-k to fix the formatting

Alan Bagel

23:53

def altsum(num):
    sign = 1
    s = str(num)
    total = 0

    for i in s:
        total += int(i) * sign
        sign = -sign

    return total

there we go

(still not golfed)

Leaky Nun

I can see that

lyxal

@LeakyNun Vyxal s, 4 bytes: Ṙ⁽Nẇ

hyper-neutrino

f=lambda x:x and x%10-f(x//10) port of redwolf's lol

Leaky Nun

@AlanBagel i think you didn't start from the units digit

Redwolf Programs

Integer division is something I really wish JS had

hyper-neutrino

23:55

|0 is so scuffed

Redwolf Programs

I've always thought \ would be a great integer division operator

Alan Bagel

@LeakyNun how about

def altsum(num):
    sign = 1
    s = reversed(str(num))
    total = 0

    for i in s:
        total += int(i) * sign
        sign = -sign

    return total

lyxal

I really wish python would let list return a list of digits if given a number

hyper-neutrino

@LeakyNun Jelly, 5 bytes: UNÐeS (Try It Online!)

Leaky Nun

@AlanBagel sure

Alan Bagel

23:57

@lyxal Me too. It would probably save a lot.

Fmbalbuena

@AlanBagel Error

caird coinheringaahing

Hmm, I wonder why :P

hyper-neutrino

hmmm

lyxal

@hyper-neutrino haha nerd

Alan Bagel

@Fmbalbuena You copied the wrong thing

try

def altsum(num):
    sign = 1
    s = reversed(str(num))
    total = 0

    for i in s:
        total += int(i) * sign
        sign = -sign

    return total

Fmbalbuena

23:58

@AlanBagel but you used backticks to mention.

hyper-neutrino

well obviously you're not supposed to copy that part lol

you can't multi-line codeblock part of a message without the whole thing

caird coinheringaahing

Anyone object to Zsh being the LYAL this time? We've definitely got an "expert" (i.e. pxeger) around, at least later

Leaky Nun

@hyper-neutrino i have 3 bytes

lyxal

looks like we learning Zsh today
