need my clown role asap

rancid creek
#

I think this is the first year where I used only python for every puzzle. No perl, no C, no solving by hand. Just python.

#

Big shoutout to those that did do it with differnt languages.

strange zinc
#

python is my go to. Then other languages after that

hidden musk
#

fenix and i used python for the prolog day and for 25

#

i forget which was prolog. 5 maybe?

rancid creek
#

Python because I'm lazy and don't want to have to write as much code.
--- followed by me writing 1000 lines of experimenting different ways to solve the same problem.

strange zinc
#

that's only half right? Each day has 2 solutions

rancid creek
#

What was the language for day 25 ?

strange zinc
rancid creek
hidden musk
strange zinc
rancid creek
#

it was 2 days ago. lol

#

I meant 1 day, not day 1

strange zinc
#

oh LOL

hidden musk
#

49? use a different language to parse too :P

strange zinc
#

the only challenge I use for AOC is to do it all without additional packages

rancid creek
#

Doesn't matter how many languages I used I'll never be as cool as the guy that did them all in intcode. ๐Ÿ™‚

#

๐Ÿ˜ฎ

strange zinc
#

havent finished this year yet. will try at some point

mossy basin
#

i spend too long on visualizations to do extra challenges ๐Ÿ˜ฆ

rancid creek
#

There was a couple libs I played with just for fun like shapely and networkx that I didn't need.

strange zinc
hidden musk
#

i didn't know the language enough to use any libraries ๐Ÿ˜ฉ

rancid creek
#

z3 was the only external lib I didn't write an alternate solution for.

mossy basin
#

thanks, i'd like to do my own language one year, but i guess that means i'd have to write one

#

actually had 3 solutons on z3 day

#

and none were z3

rancid creek
strange zinc
#

I'd love to make my own language. Dont know where to start though.
May just wait for doing the module when I do comp sci honours

mossy basin
#

i know where to start, i just haven't started

rancid creek
mossy basin
#

at least i know the books

strange zinc
mossy basin
rancid creek
#

that's python's strength!

strange zinc
#

true. It is lovely to leave it out.
but my mind. I have always used strict type hinting. Probs due to being taught that way

rapid wolf
#

I would suggest crafting interpreters instead tbh, the dragon book isn't that great at getting you to actually write a language.

strange zinc
#

due to that, pyright has become a favourite for me

mossy basin
#

inb4 i just make worse version of julia

strange zinc
#

julia is nice

cyan sleet
#

on top of 25 langs

strange zinc
#

joe_salute
Of those languages, where they all new (or most) new for you? Any that stood out as being "fun" to learn

mossy basin
#

raku

hidden musk
#

we didn't do raku

mossy basin
#

i know, but i saw it a few times and it stood out

#

it's insane

cyan sleet
#

so these are the langs

Screenshot_20231227-192333.png
mossy basin
#

day 11 could've been raku though

cyan sleet
#

ones I've used a decent amount before:
bash, lua, java, C#, C++, Rust

hidden musk
#

i was really impressed by the functional languages

mossy basin
#

didn't see any nim this year

cyan sleet
#

ones I've touched some before:
haskell, perl, php, go, ruby, kotlin

cyan sleet
hidden musk
#

f# was cute. the languages that let you have support of a big ecosystem like scala are great

#

actually usable + functional

#

clojure too

cyan sleet
ripe meteor
#

F# shill now?

hidden musk
#

some of the syntax was just odd though

#

i think i did not understand how to call functions

cyan sleet
#

did you do clojure for lisp day?

hidden musk
#

yeah

#

decided to not want to die

cyan sleet
#

meanwhile I did clisp like a cave man ๐Ÿ˜…

hidden musk
#

the parentheses dream did not come to me

rancid creek
#

(decided (to (not (want to die))))

hidden musk
#

.xkcd 224

#

oh come on

cyan sleet
#

I actually starting getting annoyed at some of the verbosity of later days

rancid creek
cyan sleet
#

granted, it's in part because harder puzzles, but also less functional

hidden musk
#

composability and pipes and chaining ๐Ÿ˜Œ

rancid creek
#

I wonder how much lisp has changed since I last used it ~30 years ago.
I suspect not too too much.

hidden musk
#

i've said it before but clojure's reducers are soooo nice

#

like a cooler version of GNU parallel

rancid creek
#

Hopping on a plane in about 8 hours. Passport still missing. Should I panic now. Think I'll finish my coffee first.

hidden musk
#

i'm sure it'll turn up ๐Ÿฅด

rancid creek
#

Yeah. The question is whether it will turn up today. ๐Ÿ™‚

ripe meteor
#

Whats there to panic about, use your id card

#

Eurobest moment

hidden musk
#

didn't you guys exit ๐Ÿ˜›

ripe meteor
#

They sure did but im an eu citizen

What are you coming here for

#

Its cold and grey and wet

rancid creek
#

mum's 75th bday.

hollow wharf
#

yo do you happen to know someone who does explain the aoc puzzles from the math view?

strange zinc
#

HyperNeutrino?

rancid creek
sleek cave
#

thought this message was about some graph traversal ๐Ÿ˜‚

rancid creek
#

Wasn't there a puzzle a year or two ago that was something akin to papers please?

strange zinc

sees day 12
ah, ||combinatorics|| is evocative of ||dp||, we're in for a fun time
wait, input size is ||brute-forceable||
||naive code|| turns out super clean lemon_fingerguns
sees part 2
๐Ÿ˜ฎโ€๐Ÿ’จ knew it won't be this easy

noble skiff
#

such a slog, I had day 23 done fo ra while but I basically re-implemented much of the logic for part 1 and 2

#

and squeezing them together turned out to be way harder than anticipated

ruby sedge
#

hi

pine ravine
#

i think i did aight

sleek cave
#

and then i realize it's brute forceable :P

#

this year's day ||16|| would be a good example

#

i had a pretty clean implementation for the ||laser and mirrors logic|| as well, so that was fun & nice

and thats in the code

#

how did you do day14 part 2 without mutating the string?

#

should i use lists of chars?

simple raven
#

I used a numpy array of chars, but list of chars would work as well

agile silo
#

i think it's quite bad that python doesnt allow string mutation

simple raven
#

so you don't like using strings as keys in your dictionaries?

rapid wolf
#

I did with string slicing personally

agile silo
mossy basin
#

i didn't make any string copies

agile silo
#

if you make list(a) and a is [[]], does it make a shallow copy?

rapid wolf
#

yup

agile silo
#

you have to make a list() out of each individual one, I suppose

simple raven
agile silo
#

well, not in python. I was talking about other programming languages such as rust

#

but Ig it's kind of a different programming language, and it is not trivial to implement mutations in strings

#

yea

#

in rust for instance you wouldnt be able to mutate the string if the dictionary owns it

#

but there is the possibility of string mutations

simple raven
#

I looked it up, rust saves an immutable copy of the string when it is used as a key, I suppose that's a decent workaround

#

then you can modify the string without affecting the key

agile silo
#

yea, basically the map takes ownership of the string

rapid wolf
#

Yeah, that's not all that possible in python

agile silo
#

i am ||mutating the grid every cycle and comparing the result to the first grid to see when i find a cycle||

#

turns out i am not finding a ||cycle||

#

as i said, the grid is a list of lists of chars

#

i checked that my code correctly performs the cycle

#

so im guessing maybe im doing something inneficient

simple raven
agile silo
stoic moat
#

is this real?

#

Some People Were Asking Why is The File Is .exe

Its Because If I Set It As .py People Will Have To Install python , modules required , pip but still people wont believe me so i will be giving source code of bot below this message.

simple raven
agile silo
#

@simple raven any idea?

simple raven
agile silo
#

i never dfound the first loop (cycle)

simple raven
#

(where I use cycle -> the 4 shifts, loop -> series of cycles that return to the same position)

simple raven
agile silo
#

oh

simple raven
#

to see if any of the previous happen to have the exact same configuration as the new one

#

that's how you find the loop

agile silo
#

i thought it was enough storing first cycle

#

but yea, what you say makes sense

agile silo
#

after doing all iterations, i have to tilt north and count, just like part 1, right?

simple raven
agile silo
#

but it says you need to count the rocks in north support beam

#

oh, you just count the rocks in each line

#

also, am i supposed to iterate anymore after finding the cycle? I mean, are next iterations all going to leave the rocks in same position?

surreal meadow
#

can anyone review my shitty day 23 solution it doesnt work for shit

#

only works pt 1

simple raven
surreal meadow
noble skiff
pine tiger
surreal meadow
cyan sleet
#

you can be more clever about compressing the graph to make the brute force more efficient, but that's about it

surreal meadow
#

yup

cyan sleet
surreal meadow
#

but my code would take like 30 minutes solve

#

what means NP?

#

anyways how long will the site be up ?

cyan sleet
#

to put NP-hard in very rough terms we don't know of any efficient solution to this problem

#

aoc? it's always up

ripe meteor
#

The channel is archived but that wont happen till feb

surreal meadow
#

damn, i hope im a whole lot smarter for next years aoc

#

just gotta get more experienced

ripe meteor
#

There are 7 more years for you to practice on

cyan sleet
#

so the insight for 23 is basically that you can compress things to a pretty small graph

#

maybe 30-40 nodes

#

rather than 1000s

surreal meadow
#

yeah i already wrote the code to find the nodes

#

which was easy

surreal meadow
#

is 23 harder than the average aoc challenge?

cyan sleet
#

so you already have the smaller graph with 30-40 nodes?

surreal meadow
#

yeah

cyan sleet
#

i.e. just keep the ||intersections||

surreal meadow
#

just counting neighbors

#

yup

cyan sleet
#

hmm, it shouldn't be super slow then

surreal meadow
#

just ||counting neighbors for every non #|| tile

#

nah my old code was trash

#

what im making shouldnt take more than 30 seconds to run honestly

cyan sleet
#

there is a simple improvement you can do:
||if you can reach the target, go to the target and don't consider other paths from that point||

well im a beginner so i dont even get level one @ivory vigil

The one I would suggest is Rust

#

Go would probably work fine too

#

But Rust is approaching C speeds whilst being memory safe if you just stick to safe Rust

i'd definitely like to learn rust

#

i don't think my contest supports it though

Bash/Unix tool for counting words/lines/bytes/chars in a file

sleek cave

oh sick

whaaat

#

i never knew that was a thing

#

would've saved me all those "word counter" (and "line counter") google searches lmao

low condor
#

Learning bash tools is so important lol

#

Like if you want to search for a string in a file, there's a good chance that grep is what you need - you don't want to waste time busting out a full language if you don't need it

sleek cave
#

i should watch an overview video on bash tools

coding challenges is good - but learning things like bash can be more practical over time

earnest belfry
#

No, it happens at the end of the year.

#

@shell finch AoC is Advent of Code.

#

It's like an advent calendar but with programming problems.

#

And it's a contest. There's a leaderboard and everything.

#

You get more points the faster you complete the problems.

But you can still do it just for fun.

(I made the error too lmao)

earnest belfry
#

Problem 3 was interesting for me but I had a lot of fun rediscovering Python with it.

low condor
#

Previous years had some fun ones though

earnest belfry
#

It's been a long time since I programmed anything seriously.

low condor
#

Day 3 was interesting to see how a lot of people botched it IMO

#

Trying to do it without preprocessing first seemed like a terrible idea

#

But a lot of people did that

earnest belfry
#

I wanted to challenge myself and try it but I kept failing.

#

premature optimization ftw

low condor
#

Day 3 I think really shows who thinks about data structures and who doesnโ€™t

earnest belfry
#

yes

low condor
#

With the right data structure itโ€™s very easy

#

Or, if you are one of the leaderboard people you can probably do it in a harder but quicker way

#

But the easiest way is to ||map full numbers and symbols to coordinate ranges || or something equivalent

#

Once you have that itโ€™s then very easy to interrogate that to get what you need

earnest belfry
#

Yeah that was my idea using ||finditer because the returned iterator has a span method that gives them to you||.

#

I probably could have done it more nicely though.

low condor
#

To be honest ||regex|| just makes it very easy. You can do it without that but it wonโ€™t be as nice to read

earnest belfry
#

regex ftw yeah

#

I used to be really into Perl so I would say I've got a good grasp on it.

magic oxide
# low condor But a lot of people did that

in my defence i got challenged to do it with convolutions so i tried to do it without preprocessing
which led to me making a solution with preprocessing just so i could debug my solution without preprocessing

low condor
#

Ah perfect

earnest belfry
#

hahaha

#

ultimately I was befuddled by an off-by-one (fixed it and got the star) but in the meantime I wrote something to use termcolor and colorama to highlight the input visually so I could count it myself.

low condor
#

Lots of people had an off by one that day

#

Of the people that didnโ€™t preprocess

#

Cos I read a lot of solutions that iterated by line and attempted to read a number by stopping when they found the presence of a non-numerical char on that line

earnest belfry
#

oh for the rows. I could see that happening.

low condor
#

Not considering the case where the number is right up at the edge of the line

earnest belfry
#

Can I post a link to a pastebin here if I put it in spoiler tags?

Hi, anyone here did 16?

im not understanding the example

the 7th line starting at 0

# 
|v-.\^....
.v...|->>>
.v...v^.|.
.v...v^...
.v...v^..\
.v../2\\..
<->-/vv|..
.|<<<2-|.\
.v//.|.v..```
#

i don't understand whats going on there

#

gets to '|' then goes down, gets to '-' goes right, gets to '/' goes up, '/' again i gess to right again, then \ goes down, '|' makes it go all down outside the thing?

cyan sleet
#

no, you're missing some stuff

#

the beam splitters send stuff in both directiona

#

and idk what you mean about the last |

#

you would encounter a - at that point pithink

hollow wharf
#

i mean i don't follow the >>

#

so the first '|' sends down, right?

#

the '-' sends left and right

#

the first '/' sends up, the second '/' sends right, the \ sends down

# 
.|...\....
|.-.\.....
.....|-...
........|.
..........
.........\
..../.\\..
.-.-/..|..
.|....-|.\

in between the '/' and \ on the purple line

also the green ones

#

whats that about

#

disregard that, i will look at it later more in depth, i'll probably try to implement it first

#

im obviously missing sth

#

no use in following up now

that will later hit the | and go down

putting yellow and red in

@low condor I refactored my stuff using timeit btw :D

I'm going to refactor it further so I can just use the same driver for all solutions. I have to look up the syntax for interfaces in Python first though.

earnest belfry
low condor
low condor
#

Using something like that itโ€™s easy then to plug those into timeit and so on

earnest belfry

because it's fun to overengineer

and I've never done interfaces in Python

#

probably better to do it simpler but I'm not competing anyways so time isn't really an issue I guess

Fair enough - if you want to go down that approach

In which case youโ€™d be looking either at abc module or typing.Protocol, depending on whether youโ€™d want to use type hinting or not

I'm against role-locking, it just adds complexity

Does Discord recommend channels that you haven't checked in your id:browse ?

earnest belfry
#

Discord hasn't suggested any channels for me but everything is checked it seems.

#

I'm using Discord in my browser though so I don't know if it's an app-only feature.

#

I can see how it would make the on-boarding more complex but it might be less confusing in the long run to choose from a smaller pool of channels.

I don't know how much of a problem it actually is though or if it even needs to be addressed.

if we will talk about an startup base companies you need to work on both frontend along with backend. so you need to know some basics in frontend, and backend is most and high payable then frontend.

uh oh

this may be me
