Q: Quickly! Group together!

This challenge will function somewhat like an answer-chaining question, in that new answers will (somewhat) depend on old answers. However, this is (as far as I can tell) a unique form of answer-chaining, so be sure to read the entire challenge if you'd like to take part. Normally, answer-chainin...

Is this a spam? At least it looks total nonsense to me

caird coinheringaahing

It isn't spam, but it should be deleted

Redwolf Programs

Looks totally unrelated to the challenge.

caird coinheringaahing

Flag as "mod intervention" and say that it isn't an answer

NAA sends it to the review queues

I need to stop posting challenges that let @Lyxal reference either 69 or 420 in them :/

@cairdcoinheringaahing good luck with that. I'll try and slip the funny numbers in wherever I can!

12:42 AM

Take a look at the comment they left underneath mine

Unrelated String

> No problems! Thanks, I need to practice with a concatenative morphology programming. I guess you have to decide - do you side with the William of Occam (11th Century Lord), or pre-know about all of the particle physics experiments at post-quantifiable CERN experiments in Geneva? The atonal nature of various eastern languages handles the NLP-aspect of it.

caird coinheringaahing

Also, this answer-chaining challenge is messing with my head. I keep thinking new answers have to follow the previous one ಠ_ಠ

Redwolf Programs

Yeah, just put that post into a markov chain and the output is very similar to the post itself

caird coinheringaahing

@UnrelatedString Personally, I agree more with the well-known Truthful Waist theorem, by Professor Shakira

No problems! Thanks, I need to practice with a concatenative morphology programming. I guess you have to decide - do you side with the William of Occam (11th Century Lord), or pre-know about all of the particle physics experiments at post-quantifiable CERN experiments in Geneva? It's related to what the Dalai Llama said in "Universe in a Single Atom", about effect and an affect, and on-linear kinematics of the real linear number line and conjugates of complexity classes backwards in space and time like-dims. — Sashmit Bhaduri 5 mins ago

@Lyxal YEAAAAAAAAAAAA

Welcome to the club

@Razetime for you, the sandbox now has 7k+ answers instead of 3k lol

oh god

Also, can you tell me if the "new answers to old questions" page is an absolute eye-sore on your device?

need to see iit

@Lyxal I'll see

Tools > new answers to old questions

1:52 AM

hmm where is it

codegolf.stackexchange.com/tools/new-answers-old-questions

10k+ only link ^

everything overflows off the page

Okay cool

So it ain't just me

I raise an issue on MSE later

It happens to me too

Okay so that's 4 confirmed cases of page ugliness

2:00 AM

wonder what they've been doing that ruined those pages

@cairdcoinheringaahing impossible

That's what I said!

Redwolf Programs

2:28 AM

That spam post still exists? I just got it in the VLQ queues

2:40 AM

@RedwolfPrograms yep still exists

Redwolf Programs

Does anyone know if voting "Recommend Deletion" in the LQP queue below 10k actually submit a VTD, or does it just "recommend" someone to do it?

Ok I'll do a test run on one of your answers

and you tell me if it tells you to delete it

Redwolf Programs

How much would y'all bet that my English teacher wouldn't notice if I used a Markov chain to generate poetry?

Unrelated String

that sounds

realistic

@RedwolfPrograms hmm what's the criteria for winning

do they have to say it's a markov chain

Redwolf Programs

2:50 AM

Just suspect that I didn't write it :p

I mean "Cloth jacket on us your side projecting steering as there he said, that bird's nest in his tread" actually sounds like a poem to me

I'll bet Rs. 100

thats about a dollar

Unrelated String

that's a solid class submission poem

your teacher might suspect it's not yours not because it seems like a human didn't write it, but because it's too poem-y
not poetic, but poem-y

rhymes surprisingly well

Redwolf Programs

Yeah, I'm surprised I got such a good one second try (I'm using Moby Dick to generate the markov chain)

Unrelated String

good choice

2:55 AM

now make it recognize meter

Redwolf Programs

Yeah, but then it wouldn't be a markov chain. Kinda feels like cheating to auto generate quality work. :p

it's not cheating if you made the program

anyway tell me if it's recognized and I'll fedex 100 Rs or something

Redwolf Programs

It probably costs way more than that to ship it all the way to Texas :p

hmm yeah

Redwolf Programs

It's fine, I was mostly joking anyway. We could bet 100-rep bounties, though :p

3:02 AM

hmm yeah thats a much easier thing to bet on

Unrelated String

imagine not having been in this convo and just seeing a bounty awarded for "bet"

Redwolf Programs

I have English tomorrow (in about 13 hours), I guess we'll see then :p

good luck

what if, to remind everyone of intcode, one of the aoc stars this year is based on fractran

lol

Redwolf Programs

Oh, the next one is only five minutes away. Hopefully it doesn't get practically DDOSed like last night.

*yesterday afternoon

Unrelated String

*last night

Ight I've got 05AB1E open on TIO, info.txt in the 05AB1E repo, IDLE with a boilerplate input parser and notepad with an empty text file all ready to go

Unrelated String

4:55 AM

lol

honestly yeah having a golflang at the ready is not a bad idea

almost want to just import jelly for use in a python script lmao

3 mins left.

Unrelated String

but there's way too much that's just in lambdas in the one big atom dictionary

Redwolf Programs

Hopefully it's something quickly solveable with vanilla JS :p

Unrelated String

lol

Not open yet, but day 2

4:58 AM

Ooh, it's AoC time again

Unrelated String

for all we know the top 20 answers are all in java

python is actually holding me back

Redwolf Programs

Or lenguage

@RedwolfPrograms yes. Just solve it all in BF

Unrelated String

and if i just did everything in an old c++ dialect my true potential would be unleashed

Redwolf Programs

30 seconds and now I need to pee

Unrelated String

4:59 AM

ikr

xD

Unrelated String

i fucked up in the dumbest way

i didn't decrement the indices

i incremented them

still got rank 122 lmao

dang it

i'm not in top 100

;(

Unrelated String

it should have been a tell that something was wrong when I had to handle out of range indices

I did hit top 100 on star 1 at least

Redwolf Programs

Me too

Unrelated String

5:06 AM

46

I made the exact same mistake for part 2, interestingly

Unrelated String

lol rip

`Because of an outage during the day 1 puzzle unlock, day 1 is worth no points.`

well

that's fair actually

but still

Redwolf Programs

I got 655th for the second part :/

Unrelated String

:\

Redwolf Programs

I messed up four separate times

Unrelated String

5:09 AM

rip

Redwolf Programs

I've dropped to 5th on CGCC leaderboard

my leaderboard position was between 200 and 300 for both parts.

Unrelated String

nice

Redwolf Programs

Looks like more people are stuck on 2 than 1 currently, I guess I shouldn't feel too bad about how I did

Unrelated String

you know, when I saw the input format, I kinda wished I'd refreshed on Python's regex library, but a bunch of splits and slicing works too

Redwolf Programs

5:12 AM

I literally read your comment about how you incremented instead of decremented, and still didn't get what you meant and got it wrong two more times :p

there we go all done

1788 and 1679

Unrelated String

oh yeah i'm actually tied with tckmn on the private leaderboard for now lol

why do i doubt that this will last

out of top 1000 again

same

definitely not a good-feeling way to test drive a new language

Redwolf Programs

5:14 AM

Is it normal for there to be so many fewer people on the second day than the first?

Unrelated String

probably

yeah probably

Unrelated String

numbers fall off just throughout the event

And this kids is why we use python not osabie

You can see last year's stats at adventofcode.com/2019/stats

5:15 AM

@UnrelatedString Yeah, I simply went with splits too

Redwolf Programs

I was expecting something like a 5% drop per day, I guess the /50[34]/ thing might have made some people decide to wait until later

likewise

I got screwed over with the stack mechanics

@UnrelatedString split gang

Unrelated String

i might unironically use jelly if jelly was easy to type and also wasn't completely hopeless with an input format like what we had today lmao

I managed to open my bookmarks tab while frantically trying to use to and stack based languages

Unrelated String

5:16 AM

oh wow

Redwolf Programs

Am I the only one who used regexes? I think it was definitely slower than splitting anyway.

nope no regex

Unrelated String

regex would probably be faster than the shit i did

maybe?

maybe less regex and more like

scanf

scanf would have been faster

Redwolf Programs

.split(/[^a-z]/) probably would have been the best option in JS, I basically reinvented the wheel by replacing it with four assorted chunks of a wheel

Unrelated String

time to homebrew a scanf for python

5:18 AM

Jelly is pretty much optimized to the CGCC's input format

Unrelated String

yeah

so it's not the best choice for something like AoC or any other programming competition that involves parsing input

And I hoped to have a scanf in Factor too :/

at least sscanf

Unrelated String

another problem with jelly for aoc is that a lot of aoc stuff conceptually involves more than three variables

My answers for day 2

Unrelated String

oh yeah i made my solutions repo public for my sister who come to think of it does have a github account but probably forgot the password

Redwolf Programs

5:21 AM

Considering making a simple golfing lang focused on string parsing and quick variable/list manipulation for AoC, with all the most common instructions in lowercase letters

Unrelated String

completely flat hierarchy because i'm lazy as hell

i feel like an optimized aoc language would be more like a shorthand than a golfing language

and it would have to be
extremely imperative
but also have top notch support for functional constructs

Redwolf Programs

Yeah, seems like it might be a fun project, although I'd probably only finish a few days before it ended

Unrelated String

yeah

Redwolf Programs

If anyone's interested, here's the code I used to solve star two.

Unrelated String

whoa

just the casual one liner

Redwolf Programs

5:25 AM

It looks like an OCR scan of something my cat would cough up

Unrelated String

reminds me of how before i found this site i used to golf python one liners with an old friend

and they were for problems we had at a regional in person competition

here's one of them

[(lambda t,s:(t.update({s:int((t['AB']**2+t['BC']**2)**.5)}) if s=='AC' else t.update({s:int((t['AC']**2-t.get('AB',t.get('BC',0))**2)**.5)})) or print('{}: {}, AREA: {}'.format(s,t[s],t['AB']*t['BC']//2)))({l[0]:int(l[1]),l[2]:int(l[3])},({'AB','AC','BC'}-set(l)).pop()) for l in iter(lambda:input().split(' '),['-1'])]

and my older golfer eyes are fucking burning because there's extra whitespace

there's so much extra whitespace

> `input here`

Unrelated String

> `input here`

Weird Chat Markdown strikes again

Unrelated String

maybe i shouldn't be talking when i forgot to print n in my star 1 solution

good thing i'm using idle like the kindergartener i am

Redwolf Programs

5:31 AM

What's with the two `input here`s?

Unrelated String

your code

^

Lol

@UnrelatedString well we're kindergartners together

Unrelated String

lol

Redwolf Programs

Wow, there's still only 6000 people who have completed a star for #2

Not sure how I got Wiwm== instead of Wow

Nooo, I got a popular question and now have 70 badges :(

5:37 AM

Am I the only one who uses a file for input?

I copy-paste the content into a text file, then read it in my program

A problem with using a cloud IDE

Redwolf Programs

True professionals lag the chrome console for 3s by pasting it into a template string with a convenient yet useless default value 😎

Unrelated String

6:10 AM

using a file for input definitely seems cleaner
but with my shitty workflow it's also slower

lol

Unrelated String

6:37 AM

wait since day 1 dosn't count i'm actually on the global leaderboard for overall at the moment lmao

75h place

6:47 AM

you're 75th overall?

mad

46th on both stars

Unrelated String

7:15 AM

just on star 1

112 on star 2 lmao

1 hour later…

8:35 AM

oh lol

8:55 AM

I'm thinking of trying to work on my attempt to create a tacit language again

Where I left it was at a point of being unable to parse it

9:14 AM

@Lyxal What kind of model are you looking at? You may want to study those of Jelly, APL, and J.

Unrelated String

If it was unparseable, maybe it tried some weird mix of fixed valence and ambivalence

9:29 AM

@Adám my previous model was based on the pattern-like syntax of Jelly

Unrelated String

@Lyxal now i'm really wondering where the parsing troubles hit

because the thing about jelly syntax is it's just a series of pattern matches

Q: What does this mysterious code do?

I came across some code and I'm trying to crack the case as to what it does: for 0 <= f <= l < len(A), the function is def foo(A, f, l): if f == l: return A[f] m = (f+l) // 2 x = foo(A, f, m) c = 0 i = f while i <= l: if A[i] == x: c += 1 i += 1 if c > (l - f + 1)/...

2:31 PM

Does code gulf just boil down to the library that's used?

@adamaero I'd say it usually has more to do with the choice of language.

Ya, that's what I mean. Isn't the "smallest source code" (or choice of language) just using some assembly code ideal for that specific scenario?

Redwolf Programs

For a few years now we've had it so every language competes with itself rather than all the others, since some (like machine code or special golfing languages) are so much shorter than, say, Java

Why not just write the assembly code for a particular challenge...

code golf alludes me...

Redwolf Programs

caird coinheringaahing

@adamaero Because a lot of the time, golfing languages (such as Jelly, 05Ab1E, Husk etc.) are shorter than assembly code. In fact, if you browse some of our more popular challenges (>15 answers), you'll usually find an assembly answer

caird coinheringaahing

I'm not voting either way. I understand why they're doing it, but I'm not in favour of it

It is kinda a "damned if you do, damned if you don't" situation tho. Either they get legal issues, or they get community disapproval. As a company, I know which I'd prefer

Redwolf Programs

Who's liable if a mod lies about being 18+? I don't think it's a crime if the mod lies, and SE definitely isn't negligent in that case...
