out of curiosity, is there like a standard way to remove errors while interpreting code
or is it just whatever works

Q: Bigram frequencies in text

willmathsIntroduction This challenge is about producing a code to count the frequency of bigrams in a text. This is super useful in cryptography. In a brute force algorithm, this code may be called many times and as a result, must be optimised to run quickly. Challenge Challenge is in Python 3 and uses N...

 
What's up with ^? Is it an okay challenge?
It's well-written but strict...
And half looks like a homework problem
Idk what to say, someone else can deal with this
 
It could do with a bit of loosening of the rules (e.g. restricting to numpy will make the code naturally slower), but otherwise its mostly ok
As for being a homework question, there's no real way to be sure, and I prefer to err on the side of caution and assume good faith
 
True. On second thoughts, it's missing a lot of the hallmarks of a homework questoin, it's probably not.
 
@thejonymyster try { run_main_program(code, inputs) } catch {error}?
Yeah, the rickroll makes me think it isn't
 
@cairdcoinheringaahing Yeah.

@NewPosts ← CMC
 
im sorry, i must have been reading something while typing
i meant comments lol
is there a standard way to remove comments while interpreting code
 
Btw, what's the deal with and ?
 
not errors >_<
 
12:58 AM
@thejonymyster if (token == comment_start) { while (token != comment_end) { token = next_token } }
assuming you've tokenised the code
 
Nice.
 
The full song is a bit too long for the permalink and chat :/
 
Really? tio.run/…
 
With the lang link + code, yeah :/
Comes to 543 characters, chat's limit is 500
 
Last 3 bytes can be removed if returning a flattend matrix is acceptable
 
1:15 AM
@cairdcoinheringaahing Jelly needs a way to count substrings, ċ only works on characters :/
 
@emanresuA I can't read that. Feel free to explain if you want.
 
Uppercase alphabet, cartesian product with self, map count in input, slice into length 26 rows.
 
Easy. Nice.
 
kA:Ẋƛ⁰$O;₄ẇ
kA          # Push the uppercase alphabet [A-Z]
  :         # and then push it again
   Ẋƛ       # over each item n in the cartesian product of those two items:
     ⁰      #     push the original input
      $O    #     and get the count of n in that
        ;   # end map
         ₄ẇ # and wrap that in chunks of length 26
^ if you want a token-by-token explanation
 
Thanks.
 
1:21 AM
@emanresuA I mentioned that a little while back
It'd been suggested to ask on meta for encryption to be synonymized with cryptography, but I was too lazy to do so
 
Link?
 
Oct 9 at 23:40, by Redwolf Programs
Can we make a synonym of ?
TIL salted caramel wasn't invented until the late 20th century
 
@emanresuA kA:Ẋ$vO₄ẇ works for 9
because for some reason, explicit vectorisation actually works in that instance
 
Oof :p

Evil idea: A screensaver where the little box is arranged so that it just bounces back and forth between two opposite corners
 
That is evil
 
@cairdcoinheringaahing ah, tokenizing is the thing i do not know how to do yet ^_^ im probably doing it bad xd
 
1:59 AM
So...I have an unopened pair of those apple wired airpod thingies they used to include with iphones. It includes a headphone-to-lightning converter. So what I'm wondering is...why couldn't they have put a headphone jack on the thingy itself so you'd use the adapter, instead of just putting lightning on it too (which is what they did). So you can't use it with other phones and/or laptops.
Wonder if it'd be worth it to buy a lightning to USB-C converter and chain it to a USB-C to headphone one.
 
> wired airpods
yes
 
That's basically what they are lol
 
well if they're wired airpods, just turn on the wireless mode by cutting the cords
5
apple doesn't want you to know this, but doing so instantly inserts Bluetooth technology inside the earpods
 
Wonder if I could get my doctor to inject a covid vaccine into it
To upgrade from bluetooth to 5G
 
2:02 AM
Lol
 
@RedwolfPrograms that's just silly
by doing so, you get back to the problem of not having a way to connect them to your phone/device
 
@RedwolfPrograms But seriously, I might do this
 
idk much about connecting that sort of stuff. I just use my wireless headphones
 
I don't listen to enough stuff for headphones to be a smart investment
Although in a few years I'll probably need some since then I'll be going to college and I don't need my roommate judging me for my meme choices
 
they don't have to be those high quality make the audio 69x better trendy brand type
just wireless
 
2:05 AM
I should just get airpods so it can smell like broke in here
 
okay zoomer
side note: Binary Search Trees are cool until you start having to deal with encapsulation and a lack of lambdas/functional programming in C++98
 
Just transpile Vyxal to C++ and hand that in!
 
bruh the assignment is due in 6 days, not 2 years
 
Use a Python-to-C++ tool then
 
bruh the assignment is due in 6 days, not 2 years 6-8 months
 
2:11 AM
@NewPosts I'm temtped to answer in transpiled Vyxal
 
do it
it'd be funny
 
Gonna make it a little efficient tho
 
You're lucky it isn't code golf
 
Python-to-C++: hardcode Python code as string, link against CPython and run it as Python
 
otherwise your submission would be at least 700k bytes
@lyxal I say 6-8 months, because I would not trust 2.4.1 transpiled code, meaning i'd be waiting for 2.6 to be finished
 
2:15 AM
For a second I thought you're talking about Python version
 
Hmm, the only way I can figure out to plug a lightning cable into an audio port requires three separate converters
Lightning to USB-C, USB-C to audio, and audio male-to-male
Costing a total of...$40
Might as well buy wireless headphones for that much >:|
 
And somehow the main site went down
 
Not for me... Is it back up for you now?
 
Then it's corporate firewall going crazy I guess :/
Even downforeveryoneorjustme.com doesn't open

10:25 AM
@Anush I assumed a system of equations, but the general solution for single equation with 4 variables is the same: linear combination of 3 nonplanar vectors.
For the record, LLL doesn't help solving it in the first place. It takes one such set of vectors and refines it to a better one
 
@Bubbler rak1507 had a trick I think to use LLL I think. But most languages won't have LLL built in so it's not too important
@Bubbler yes. I guess that's not too trivial in most languages

This question mentions that it is on-topic on main according to consensus, but I wonder if it should be on meta anyway, since that is where questions like that typically are, and it feels like that would make more sense.
I know meta is the first place I would look for questions like that.
What do y'all think?
 
That should definitely be a meta question I think
Although it depends. I think is also supposed to include writing non-CGCC challenges

its for my marijuana pipe, you see
you can do it red wolf youre a smart :-)
dumb challenge idea: Naive code-golf, you have to do X but your code is only scored on printable/visible characters (so white space gets score 0 ofc but thats besides the point)

Quite the range of opinions
There's a citation after that from someone named "Barry Kaye" but it only had the last name and I read it as "Kanye"
 
oh kanye and his opinions
 
@thejonymyster that could potentially give Vim a pretty good score
 
You could probably use spaces and tabs to encode lots of information in JS/Python/other languages and convert that into a string to eval
 
that exactly what i wanna see tbh
 
Sandbox it!
 
3:18 PM
i guess my only concern is like, a particularly short answer with no unprintables could just as easily do better than anything lol
 
Make it a very difficult challenge to solve succinctly then. Maybe a kolmo or something.
 
it could potentially devolve into "Write the shortest code possible but youre allowed to use whitespace freely so have fun with newlines n stuff"
ooh ok
smart
dilemma though
 
@thejonymyster It'd still be fun to see how we can lower our score in other languages, e.g. a longer Vim score might do better by using unprintables in a roundabout way

Q: Write some Genetic Quines

Redwolf ProgramsIn this challenge, you'll create some programs which behave similarly to genes.

As...

@RedwolfPrograms redwolf your imagen't'd
 
Fixedednty
 
ah there it is lol
ty
 
I'm trying to think about how you'd do this in a practical language. You'd probably need each allele to be a payload-capable quine, then have each one have a 50% chance of returning itself, and follow it with some sort of code that would chain with the start of the second allele to make it return otherwise, and do nothing at the end of the second allele
 
are there any tips up about writing a good kolmo? i have no idea what id do for that
i guess in general i dont know what would be an interesting challenge for unprintable chars lol
i just know i like the framing, but that isnt enough to work with at my level >.< lol

Seems like it would be more boring than a harder actual-challenge though, since you'd be encoding the info itself with whitespace rather than code
So maybe a really tricky actual-challenge would be better, although those are hard to come up with
 
right, lol
and then you get to "so why have the whitespace thing then"
 
Well because it makes it interesting :p
 
id think a tricky actual-challenge would (have to) be interesting on its own lol

SegganScrabble Word Finder Yes, I know there is a similar question, but this one specifically concerns any possible words, even with letters left over, while the linked one restricts to a permutation of the input Objective Have you ever had those moments in a Scrabble game where you're staring at you...

 
ill start brainstorming, but i did just have one off the fly idea
well let me make sure it doesnt exist first lol
 
There's a similar one for abusing a rule about counting characters instead of bytes
 
maybe worth crosslinking, but id say thats different enough
plus if the challenge itself is different and interesting too, itd probly be fine
hm, i cant actually tell if its been done but, fizzbuzz but for all primes? itd be prime checking and string generation ig, i wonder if thatd be interesting enough
 
3:43 PM
Probably not
 
@thejonymyster a large part of fizzbuzz is combining the fizz and the buzz, but with primes, there would only be fizz
 
i dont follow
i meant like
instead of just 3 and 5, any prime
i guess itd be just prime factorization though, but instead of the factors, strings
eg 1 fizz buzz fizz foo fizzbuzz bar fizz buzz fizzfoo
but yea, i can probably do better
 
sorry I misunderstood
 
What about implementing one of the more complicated KotH answers you can find (and get permission to use)? Those tend to have lots of interesting stuff, and can get super complex.
 
@Wezl no worries, i can see where my language could have been clearer anyway :-)
@RedwolfPrograms getting permission sounds boooooooooring :P maybe lol
im trying to formulate the words for my hesitation on that idea
 
3:57 PM
@RedwolfPrograms I think I may ave just broke your challenge. :P
 
Lol. I should have thought more about how the alleles could all just be the same but with some number or letter changed :p
So the penalty/bonus is basically nonexistant, but that wasn't the main focus anyway I guess
 
what is your score, btw grain ghost?
 
0
Or I can get as close to zero as I want by adding more programs.
 
No, just over 98
It's only the bonus/penalty that decreases to be effectively 0
 
Oh that's a bonus.
 
4:00 PM
oh right
 
The scoring section is a little confusing.
 
It is, yeah. I tried a few ways of wording it and that's the best I could figure out.
 
> Your score will be the average byte count of all of your alleles, plus an amount...
 
Your score is 98.0000029206276 :p
 
I might be able to get that a little higher by adding 2 allele programs.
idk
I'm not really interested in finding otu.
 
4:02 PM
lower is better though :P
 
Since I never really golfed the program in the first place.
 
well gg, G.G.
 
4:19 PM
Ok well I realized I had a very silly bug which added a lot of bytes to fix. But now the score is within floating point error range of the allele size.
 
5:03 PM
@AaroneousMiller yes thank you. I'll try again in a bit b:)
 
Idea: A language where basically everything is a dictionary, except one value that isn't and errors with the typical dictionary operations.
Even better, name it almost identically to an existing language so it confuses people.
And then make the type system super weird, and have primitives that are still sort of dictonaries but not really, but they don't cast the way you expect they would

5:34 PM
@RedwolfPrograms wow, this is the best language idea ever. We should package it with all complete web browsers before testing it on different platforms
 
And have a bunch of people add more features specifically because the other one doesn't have it, so that the standards are inconsistent for a decade and backwards compatibility is a complete nightmare
 
5:46 PM
@RedwolfPrograms You completely omitted the red vs blue functions feature!
 
Because I see nothing wrong with JS's async
I used a markov chain on five songs and it gave me this
 
idea: gather up a group of practical languages. Split into two teams. team one builds a new language using the best features of the languages given. team two builds one out of the worst features
 
So for the bad, e.g. you want verbosity of built-ins as in Java, but entirely spelled with non-ASCII symbols, like APL.
 
yes :-)
 
@Adám Specifically, we use symbols that don't render for most fonts.
 
5:55 PM
@AaroneousMiller Do any languages do that?
Ah, Mathematica. Right.
But you'll end up with contradictions in the good. E.g. you'd want mnemonic Unicode symbols of APL, with ASCII-easy typeability.
You'd want full control over memory from C, while you don't need to worry about memory management from various interpreted languages.
 
why contradict when you could simply have both
 
Neat whitespace flow from Python with whitespace insensitivity from many other languages?
 
ok that breaks i suppose
wait, do people like significant whitespace
 
Some apparently do.
How about easy line continuation from C etc. while line breaks end statements from, say APLs.
