Wow ... I'm actually surprised how competitive Madagascar is. I made it as more of a joking-but-still-legitimate answer, but it's doing surprisingly well.
@CᴏɴᴏʀO'Bʀɪᴇɴ Then at the very least, send it in the Sandbox! We will see if staff and people will make the sequel have good reception.
@TimmyD If it is a joking-but-still-legitimate answer, it's a joking answer. Delete it.
@zyabin101 If you want, you can do the challenge.
@zyabin101 Joking answers are still okay.
I have guidelines that decide when I should participate in a challenge. One is that I skip those that have a full page of "parsing rules".
@Geobits Are those free or proprietary?
My guidelines? Proprietary.
Get your own :P
14:04
@Geobits Too bad.
Holy crap. After five days, it's finally moved from "Processing Order" to "Preparing for Shipment". Never again.
@Doᴡɴɢᴏᴀᴛ I like your new avatar, but where is Leftgoat? And how to get this leadboard to work?
@Geobits What?
A thing from the thing place. Slowest order processing I've seen in at least a decade.
@Geobits What exactly?
14:08
The thing.
@zyabin101 It's a better answer than the onslaught of "End-of-the-world" bots, which could be argued as EmoWolf and should be trashed accordingly.

@Geobits What exactly?
I'm not sure why you think bold or italics will get you a better answer.

ok.. new challenge idea... multiply polynomials with very large coefficients
as in 1000 coefficients each of which has 1000 bits
@Lembik UHH... Another math challenge. UHHHH!!!
@zyabin101 yes! We don't have enough :)
@Lembik We never have enough. :]
@zyabin101 well.. actually there is basically no math in this challege... multiplying polynomials is like multiplying integers but easier
but golf or fastest-code.. that's the question!
@Lembik Golf.
It's the most popular challenge type.
Here, at least.
14:12
@CᴏɴᴏʀO'Bʀɪᴇɴ I don't really know what that means.
@Dennis "Is Jelly turing complete"
@zyabin101 that's a reason not to do it :)
@zyabin101 There are a few things I don't like about golf challenges if anyone wants to hear them :)
@Lembik Then fastest code or binary golf?
Yes, I don't really know what Turing complete means.
oh what is binary golf?
14:14
@Dennis Oh.
@Dennis it means can compute anything that is computable by anything :)
BF interpreter in Jelly, gogogo
UHH... *wiki*[turing completeness]
If your language is capable of looping, there's a good chance of it being TC. If your language can simulate another turing complete language, it is turing complete.
In computability theory, a system of data-manipulation rules (such as a computer's instruction set, a programming language, or a cellular automaton) is said to be Turing complete or computationally universal if it can be used to simulate any single-taped Turing machine. The concept is named after English mathematician Alan Turing. A classic example is lambda calculus. A closely related concept is that of Turing equivalence – two computers P and Q are called equivalent if P can simulate Q and Q can simulate P. The Church–Turing thesis conjectures that any function whose values can be computed by...
@CᴏɴᴏʀO'Bʀɪᴇɴ if your language can simulate a nand gate it is likely to be turing complete :)
@CᴏɴᴏʀO'Bʀɪᴇɴ Sell carrots. You should see the wiki post directly above you.
@zyabin101 Wikipedia is too long.
@Lembik That is also true :P
@Lembik Not necessarily, e.g. Befunge-93 :P
@Sp3000 Darn, I was Ninja'd by a few minutes!
14:16
@Sp3000 see "likely" :)
14:28
TC and the theorems and related work surrounding it (like the halting problem) are really fascinating. The Church-Turning thesis itself is mind-boggling.
@TimmyD yep :)
but it's not a theorem
I can see how my wording was confusing. I apologize.
no problem!
I kinda want to take this time to vent about my Into to Linux professor.
you have an intro to Linux professor!
that's already amazing :)

A: Sandbox for Proposed Challenges

Cᴏɴᴏʀ O'BʀɪᴇɴLegendre Symbol Repetition Finder The Legendre Symbol is a number theoretic function that returns -1, 0, or 1. Here, we are particularly interested in the pattern it forms. Observe: n\k 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 24 26 27 2...

or is it that you can't understand what they are supposed to do?
but I love that you have to write bash scripts at all. That's very old skool
14:33
Any suggestions for other test images for my challenge? meta.codegolf.stackexchange.com/a/8186/24877
So we have a giant "dictionary" of words (one on each line), and 1 question is to grep every word with "exactly six consonants in a row." (consonant being anything except aeiouAEIOU)
ok so that's clear isn't it?
@PhiNotPi what is unclear about that?
But, apparently Db16000 (which counts as 7) fullfills the requirement.
@flawr your examples look great"!
Anything that counts digits as consonants is just wrong anyway o_O
:s/exactly/at least/g
yes that is surprising :)
@Lembik Thanks, but to be fair, I did not paint all of them myself.
@flawr :)
@flawr just the bottom one?
And the thing is, he grades our stuff programmatically, so we have to get it right.
14:37
@Lembik Well basically the ones on the right side=)
@flawr :)
@Lembik I think I'm going to release that one today.
@flawr great!
any thoughts about my polys with large coefficients?
A challenge?
yes.. multiply two polynomials with very large coefficients. For example, 1000 coefficients each other 1000 bits
14:40
And he tends to throw trick questions at us, like "1) get all csv files. 2) Get all csv files from the month of August. 3) Get all files from the first 9 days of August." And then most of the class gets the 3rd one wrong because he left out the word "csv"
@Lembik Link?=)
So you want people to use DFT?
@flawr Use ImageMagick, convert -size $SIZE_HERE -seed $RNG_SEED_HERE plasma:fractal a.png, and here you are - infinite masterpieces for your pleasure (and use in your challenges)! And no need to credit!
For more types of images that can be generated, check out imagemagick.org/Usage/canvas.
@flawr a fastest code one would probably be DFT with a twist because the coefficients are so large
@PhiNotPi If it's causing academic hardship, you could approach the dean or the head of the college.
Or the department chair.
@TimmyD It's really not worth my time.
14:51
@PhiNotPi I haven't really worked out what the serious problem is
It's not really that bad.
the question did apparently define a consonant as
"not vowel"
"Make a word using only not vowels i.e. consonants!" H3ll0!
@CᴏɴᴏʀO'Bʀɪᴇɴ Gwynnlynndyg!
(assuming y is a consonant)
14:55
@CᴏɴᴏʀO'Bʀɪᴇɴ that is all consonants!
TBH, it's not really that big of a deal, it's just that I was feeling frustrated with the whole "six consonants in a row" thing because we'd already asked him whether or not more consonants mattered, and he just replied "exactly six consonants in a row."
In a row, not all rows...
@PhiNotPi I think it matters what the full instructions are "Includes exactly six consonants in a row" is different from "Equals exactly six consonants in a row" for example
Let me see...
> Output all the words in the dictionary $HOME/words that have exactly six consonants (non-vowels) in a row.
15:01
@PhiNotPi The words are located in /usr/share/dict/words.
@zyabin101 What is ImageMagick?
@PhiNotPi I think that is clear. If I ask you to list all the words that have two consonants in a row you wouldn't just output two letter words
@flawr ARGH! Here it is.
@Lembik I know, it's clear that other has two in a row, it's just that I wouldn't typically think further has "exactly 2 in a row."
hmm.. so 1234567 is meant to match?
15:05
yes
ok that is a bit odd: )
:)
See?
but I still the prof is correct in an annoying way :)
he/she is trying to teach you to be pedantic
15:06
It's the easiest class in the world, but the most difficult thing is figuring out what he's asking for.
just be really really pedantic is my suggestion
@Lembik s/he\/she/xe/
@CᴏɴᴏʀO'Bʀɪᴇɴ ?
@CᴏɴᴏʀO'Bʀɪᴇɴ Can you explain again what this means?
@Lembik He's basically said that outright, about how "in the real world" we need to provide "exactly" what the contract is asking for or we won't get paid.
And so I feel like I'm being forced to "rules-lawyer" the entire time.
15:07
@flawr cc @Lembik Xe is the alternative gender-neutral pronoun.
Experimental, but it'll catch on.
@PhiNotPi well that makes some sense. Also if you are writing code to fit a protocol
@CᴏɴᴏʀO'Bʀɪᴇɴ it's no good :)
@CᴏɴᴏʀO'Bʀɪᴇɴ i think gender-neutral they is more likely to catch
yep
@primo Yeah, but i use xe around my purist english teachers :P
15:08
math people sometimes just alternate which is funny
you have to remember that he never means he
is xe pronounced she?
@CᴏɴᴏʀO'Bʀɪᴇɴ Use Meta Stack Exchange for this.
@zyabin101 I was joking...
@Lembik i would pronounce 'xe' the same way as 'he', actually
@primo sexist pig dog! ;)
same is in TeX
15:10
that would be key!
@Lembik I'd pronounce it 'zee' or 'ksee'
what would donald trump do? That's the main question :)
win so much he'd get bored of winning
he'd hire the world's best team of pronunciators to figure it out
15:12
we need a trump-trolling tag
@ETHproductions pronounced zee
/zi/
Oh hey @CᴏɴᴏʀO'Bʀɪᴇɴ
@ETHproductions hi!
I need to go back over your guys' suggestions from last night
15:13
why not use an actual z then? :(
ze, or zhe or something
"Where is ze?"
@Lembik In my opinion, it should be pronounced /ɧi/
In Swedish phonology, the sj-sound (Swedish: sj-ljudet) is a voiceless fricative phoneme found in most dialects. It has a variety of realisations, whose precise phonetic characterisation is a matter of debate, but which usually feature distinct labialization. The sound is represented in Swedish orthography by a number of spellings, including the digraph ⟨sj⟩ from which the common Swedish name is derived as well as ⟨stj⟩, ⟨skj⟩, and ⟨sk⟩ before front vowels. The sound should not be confused with the Swedish tj sound [ɕ], often spelled tj or k in Swedish. The sound is transcribed ⟨ɧ⟩ in the I...
nice!
this is exactly how americans say 'he'
how are e instead :)
15:14
ye
hear ye
wait a minute... isn't ye actually gender neutral?
wth people
What would be the gender-neutral for of "him" then?
@primo I think ye means you
derp, yeah you're right
@ETHproductions Xer
15:18
"What's up with xer?"
Ah, that makes more sense
But it seems a little too far from either side to me
And it sounds too French
I thought we decided on "singular they" ...
2
15:21
How about "xem"?
@TimmyD Oh, yeah, uh, that works too
complication:
say, "Where is he?"
now say, "Where is xe?"
@TimmyD That's what I prefer too.
hard to distinguish when spoken quickly
@TimmyD But it's more fun to add even more words to the 100 tangled webs that make up English
Hehe.
15:22
@primo Maybe a liaison? Where isje?

@ETHproductions Is that when someone is simultaneously your brother and cousin? I thought that didn't happen outside of remote rural areas of the American South.
Noun: nibling ‎(plural niblings)
  1. (uncommon) The child of one's sibling (in other words, one's niece or nephew), especially in the plural or as a gender-neutral term.
  2. 1989 November, Gacs, Women Anthropologists: Selected Biographies, University of Illinois Press
  3. She was close to her family, particularly her younger “siblings and niblings.”
  4. 1998 May, D.J. Kruger, Relative worth across disparate types of assistance [1]
  5. Kin selection was strongest for choices between sibling and friend, decreasing across sibling vs. nibling, nibling vs. friend, and nibling vs. cousin.

@TimmyD Stupid wiki icon!

not complicated enough
it needs to be different for older siblings and younger siblings, and whether it's your sister or brother
or we could all just start speaking thai and be done with it
@primo All different in-laws should have their own names. Husband/wife of brother/sister, brother/sister of husband/wife, and gender-neutral forms.

I have two strings S and T both of the same length n. I would like to output the Hamming distance between every prefix of S and every suffix of T of the same length. That is HD(S[1,i], T[n-i+1, n]) for all i.
how quickly can that be done?
TL;DR - our ops team is a bunch of ninjas. https://twitter.com/github/status/693102575223205888
@Lembik Seems like it should be pretty fast, assuming the strings aren't huge
I drew it up in haskell real quick and it seems to be instant on reasonably-sized inputs

Q: How did this user format this comment in this way?

catthis is really a very inconsequential question, I'm just curious. This is a comment on KOTH: A world wide pandemic: At least to my browser's rendering engine, there's a fairly clear difference between the struckthrough text and the other text: both font style and font size. As we can see, ...

@Lembik It looks like a million would need either a better hamming distance algorithm than I have or a more powerful computer to terminate in a reasonable amount of time, although it would terminate if you let it run long enough regardless
@CᴏɴᴏʀO'Bʀɪᴇɴ How do you pronounce taht?
@KevinW. right.. I was wondering about a better algorithm
="sie" in german (she, or they)
17:02
@Lembik Can you use the previously calculated distance (i-1) to calculate the distance for i with a single extra calculation?
@trichoplax that would be great! but I am not sure how
@Lembik Just realised that all the locations are shifted by one so this doesn't work (would only work if both were prefices or both suffices)
@trichoplax right
Maybe find someone who has a skill for parallel algorithms and feed them all at once to a GPU?
:)
actually I think I solved it#
the solution is to pad T with n zeros and then perform convolutions using FFTs :)

The Room is a 2003 American romantic drama film written, directed, produced by, and starring Tommy Wiseau. The film is primarily centered on the melodramatic love triangle among amiable banker Johnny (Wiseau), his fiancée Lisa (Juliette Danielle), and his conflicted best friend Mark (Greg Sestero). A significant portion of the film is dedicated to a series of unrelated and unresolved subplots involving the friends and family of the main characters. Ross Morin, an assistant professor of film studies at St. Cloud State University in Minnesota, described The Room to Entertainment Weekly as "the Citizen...

Rubber is a 2010 French independent dark comedy film about a tire that comes to life and kills people with its psychic powers. It was directed and written by Quentin Dupieux. The film was shown at the Cannes Film Festival in 2010. The film received positive reviews from critics, but it was a box office failure, grossing only US $100,370 on its US $500,000 budget. == PlotEdit == A group of people in a California desert are gathered to watch a "film". A sheriff, Chad (Stephen Spinella), points out that many moments in cinema happen for "no reason", that life is full of this "no reason", and that...

Anyway, the user has uploaded five files. Some of them turn out to be duplicates. I must ask the user a trinary question, and present three options:
- Proceed and overwrite the duplicates
- Proceed and do not overwrite the duplicates
- Abort the entire operation
I'm having trouble coming up with a concise, clear question and three options that fit on a button like "Continue" and "Abort"
I have no desire to see The Room though
All three of those would make for rather large buttons
