A: Sandbox for Proposed Challenges

Add a hidden language to a polyglot Inspired/mostly copied but I don't think it's a dupe. Also Inspired. In this challenge, you will create polyglots that include all languages from previous answers, and another language which you won't share and others must guess. The first language prints 1, th...

^ Any feedback?

Nobody

02:11

> s this too similar to either of the linked challenges? I feel like having to include every previous language instead of just two will really change the way people write answers and change the challenge itself.

I think this is a little hard but codegolf is a big community

hmm, sounds easy in mariolang...

teacher: you son of a XXXXX

this is python class ;-)

hello? ping @emanresuA for your feedback

ATaco

It says algorithm, not program

Thus, submit esoteric pseudo code

Nobody

actually

i omitted the part that said no pseudo code

ATaco

Darn, malbolge it’s is

Nobody

mariolang

wait how do i compile c++ again

ATaco

02:27

gcc?

Or g++ if that’s your style

Nobody

do i have to install gcc

@ATaco

i remember there was a command like

make jcklcwejkl

@ATaco?

@ATaco you there?

Unrelated String

do you have a makefile

Nobody

how do i chekc

thnx

Unrelated String

it would be called Makefile

Nobody

i'm using mac now

so

in cmd

> Makefile?

Pyautogui

02:36

Makefiles are not OS-specific, IIRC.

I have used them on both Linux and Mac.

Nobody

i mean

Pyautogui

I simply type "make <xyz>" into the command line (bash, in my case).

Nobody

how do i check if i have makefile

Pyautogui

ls?

Or the Finder?

ls that is.

Bash command.

Quite useful.

Nobody

i don't have make

> make is not recognized as a command blablabla

Pyautogui

02:38

Install it. I think it comes with xcode command line tools.

If not, maybe brew has it?

Sorry.

Nobody

how do i instakll brew?

@Pyautogui on windows currrently

Pyautogui

K

Got it. I thought you were on Mac.

Nobody

holy shit i typed the wrong thing

Pyautogui

Sorry, my advice is quite useless than; no experience with windows.

Nobody

i'm using windows now sorry eff it

Unrelated String

02:39

you probably want to just use wsl then

Nobody

how

i suck at windows

Pyautogui

Yeah, Windows Subsystem for Linux.

There are tutorials online. May I recommend looking it up?

They are quite good, IMO.

Nobody

or how do i install makefile

or any other way

to compile c++

Pyautogui

Frankly, I again have no Windows experience.

Unrelated String

you'll have to write the normal command for compiling it in the makefile anyhow

Pyautogui

02:41

I wish I could help.

Nobody

like how...

i suck at this...

i suck at windows

i suck at c++. COMBO

Unrelated String

google is your friend

Nobody

is there a way to not download anything

i'm afraid my computer will crash, it's on 100MB something

@UnrelatedString

running the esolangs thing

github.com/tomsmeding/MarioLANG

will it work if someoneelse compile it for me wonderin

Unrelated String

i mean you could use an online interpreter if you want

Nobody

well

which do you recommend

cuz the input is a file like

aaa.cpp file.txt --flags

@UnrelatedString

thnx

Hello!

Anyone up?

lyxal

I think so

I dunno. Maybe not. :p

graffe

:)

in python, what is the golfiest way to convert a list of lists into a single set containing all the elements of all the lists?

Aiden Chow

@graffe one way i can think of at the moment: lambda l:{i for a in l for i in a}

graffe

@AidenChow that is nice and elegant too

Aiden Chow

04:04

@graffe even shorter: lambda l:set(sum(l,[]))

graffe

@AidenChow oh that’s quite evil :)

emanresu A

@AidenChow {*sum(l,[])} I think

Aiden Chow

@emanresuA yeah that also works

emanresu A

I'm honestly surprised that sum works on lists like tha

lyxal

Reminder: last new-content lecture begins in 1 hour 53 minutes

Logic languages this week

Aiden Chow

04:08

@emanresuA ye me too, i didnt come up with it myself, i found it on stack overflow lololol

sum(l,[]) is apparently really inefficient, but this is code golf, so whatever :P

emanresu A

@lyxal Ooh yeah

PyGamer0

@Nobody i used to use msys2 before switching to wsl2

and before msys2 i used to use cygwin

msys2: msys2.org cygwin: cygwin.com

install either one of those and be sure to install c++ and some utilities (including make)

graffe

04:30

@emanresuA that’s great

Nobody

@PyGamer0 ok nvm got an online one

anyone know murderousmaths.co.uk?

i find that 2022 image very stupid

they say in an email

emanresu A

@Nobody Do not use inspect element there if you value your sanity

Their website is built from a hideous kludge of tables, images and iframes

It's like a website from the late 90's

Nobody

> that property is [...] rare

@emanresuA i don;t [value sanity]

> that property is [...] rare

which is not true

CMC: for all numbers 1 to 10000 find numbers that do not have that property

PyGamer0

04:39

@Nobody which property?

how property?

land property?

Nobody

an x has this property if x^2 = a^2 + b^2 + c^2 for a triple (a,b,c) positive integers.

PyGamer0

what is x?

Nobody

2022 in that image

PyGamer0

oh so you mean for every number determine if it cannot be a diagonal of a cuboid with integer sides

Nobody

find alll x that DONT have this property

yah

@PyGamer0

PyGamer0

same difference

Only because you reminded me :P

Anyone?

or say how do i check if a num is neg?

I recently noticed that CGCC has an ability to trigger a silly edge case in tag badge awarding

Nobody

what?

ais523

on the "add a language to a polyglot" question, stasoid now has the requirements for a gold tag badge (200 answers, 1000 reputatoin) with answers to a single question

stasoid has posted over 200 answers to that question and has over 1000 total rep from upvotes to them

Aiden Chow

yo dang i never see u in chat before @ais523

ais523

this means that as long as we make any of the question's tags tag-badge eligible, we can get a tag badge to be awarded from a single question, which is the sort of silly thing that I love doing

all we need for that is to post another 4 good polyglot questions

@AidenChow I don't come here very often, Stack Exchange's chat system is really annoying

or, might be 1000 score, not 1000 rep, but I think stasoid might have that too

Aiden Chow

06:13

@Nobody maybe keep subtracting one from both num until one hits zero, then figure out which num hit zero, the other one is greater

ais523

yes, 1000 score

I do read TNB much more often than I post, because if you know what you're doing it's possible to read chat without enabling JavaScript

Nobody

@AidenChow can you give me a program if applicable thnx

Aiden Chow

@Nobody idk mariolang but the symbols seem similar enough to brainfuck that im sure u can port it over easily: stackoverflow.com/questions/6168584/…

ais523

it does make sense for me to drop in and say something every now and then so that I'll be pingable

Nobody

@AidenChow brainfuck version ok too

Aiden Chow

06:20

@ais523 huh thats interesting

Nobody

oh isee

ais523

actually SE became a lot less readable without JS very recently

the "active", "oldest", "votes" sort buttons used to work without JS

but when they changed to a drop-down, that stopped working

Aiden Chow

so why turn off javascript anyways

ais523

you can still change the sort order by manual URL editing but they changed the URLs, and I'm finding it hard to remember the new ones

@AidenChow because most sites use JavaScript for things that make them more annoying rather than more usable

4

Nobody

for instance ads

Aiden Chow

06:22

but i feel like disabling javascript makes it even more annoying than with it on ?

a lot of site functionalities wont work right

Nobody

sometimes

Unrelated String

sometimes

Nobody

sometimes not

depend on which site

@UnrelatedString clash ;-)

Aiden Chow

@Nobody pretty sure u can just use an ad blocker, dont need to disable javascript

ais523

yes those functionalities normally make the site worse

Nobody

06:23

@AidenChow well aren;t they similar?

ais523

I do sometimes have to bring up an element inspector to delete cookie warnings or make collapsible/spoiler blocks visible, though

but that isn't too hard with practice

Nobody

yep

i regularly edit a site's html for printing

ais523

(it is very frustrating that sites don't just use <details> for this; HTTP has an element specifically for collapsible regions and yet everyone rolls their own)

Aiden Chow

well im not smart enough at website stuff to be able to do that :|

Nobody

erm it is actually pretty simple

i've never LEARNED html for a start

except <h1> </h1> which aout everyone knows without learning it

ais523

06:25

h1 is strange, if the page contains it more than once (apart from in some special cases) then someone has probably made a mistake

and yet SE lets you just enter it in posts

there seems to be something of a formatting war between people who use h1s at the top of codegolf posts and people who use h2s (and the occasional h3 or bold text)

Aiden Chow

huh i dont use html tag in codegolf posts at all, i just use the # thing

ais523

# is how you write <h1> in Markdown

Aiden Chow

oh rly, didnt know that

ais523

likewise, ## is h2, and so on

Aiden Chow

what about ## and ### and so on

oh

answered my q as i said it lol

emanresu A

06:33

@ais523 I have one in the sandbox, although I'm not suure if it's too similar to the ones it's inspired by

ais523

I saw that in backscroll

Nobody

I want it to be published RIGHT NOW i can't waait

I'll do python3.10, python3.11, python3.8, python2.7

3.11: better error messages

ais523

it's a bit strange having created one of the most popular questions on CGCC – we historically have had issues with people seeing highly-voted bad questions and using them as inspiration, but using good questions as inspiration has its own issues

Aiden Chow

@Nobody lol ok isnt it supposed to be hidden tho lmao

ais523

it's never clear what you would or wouldn't have to do to capture the same magic

Nobody

06:36

well it would be pretty apparent

3.10: walrus operator

emanresu A

@ais523 Yeah, especially a certain one

Nobody

python3.8: division

ais523

fwiw, I've been pondering my own idea for a new polyglot (but not answer-chaining) question, with the idea being to write a program that takes a description of a program in some simple Turing-complete language, and generates a polyglot that has that behaviour in a number of different languages

Unrelated String

ooh

emanresu A

@ais523 I doubt any question nowadays will ever be as popular as questions from the past, just due to the site culture

ais523

06:37

but it's hard to find a working set of details, especially in terms of the scoring, submitting an answer and saying "this works in 145 different point releases of Python" is quite hard to stop

ATaco

CMC: in as few comparisons as possible, given 3 values (bytes for the sake of the challenge), determine and return the median. That is, the middle value when sorted.

emanresu A

@ais523 That could be very interesting...

ais523

@emanresuA well, this comes down to how many people you can get to vote on the question, which basically always requires votes from outside CGCC to hit a very high number

an interesting experiment was this question – I realised it was inevitably going to hit HNQ and get a huge number of upvotes regardless of what I did, so I decided to go all out and see how many gold badges I could get from it (I was aiming for two, I actually got three)

this is hard to do nowadays, not just because of changes to site culture, but because most of the questions that could capture that sort of attention have been asked already

emanresu A

@ais523 There's a reason most polyglots have different goals for different languages...

ais523

@emanresuA indeed, but I think it's a shame – parallel-code polylgots are much more interesting than the comment-splitting version, but too difficult to define objectively under CGCC rules

about the only way you could make it work would be to make it a popcon…

actually this is almost a decent task for a popcon, the main issue is that a good answer takes too long to write, which is death for popcons due to the specific way in which SE's voting system is broken

emanresu A

06:42

One of the most popular questions recently gained a lot of upvotes simply because of current events. I think this might've been simply because people percieved upvoting it as a way to support Ukraine, even anonymously

The author repeatedly tried to replicate it, with no success.

ais523

well, the "zoom in on the Swedish flag" answer was incredibly funny, even if it broke the rules

Unrelated String

^

emanresu A

That was me :)

ais523

the best way to make a question take off is to have one really good answer

AaLTaP had a much rougher start, I think it may even have been closed at one point?

emanresu A

Hm okay

Aiden Chow

06:44

da hell is aaltap

hyper-neutrino

@ais523 yep, in fact this is massively reflected in the HNQ algorithm

emanresu A

@ais523 There's the trending sort option they're testing, but whether that'llreally work

hyper-neutrino

(idk how much you know about it already)

ais523

@AidenChow an abbreviation for Add a language to a polyglot

the default.

@emanresuA for some reason it's missing the "Ukraine"~CountryData~"Flag" Mathematica answer. edit: apparently they banned built-in flags :(

ais523

06:46

@hyper-neutrino unfortunately, way too much

hyper-neutrino

ah

ais523

I got very good at gaming the SE reputation altgorithm, in my previous incarnation

but that wasn't much fun and made the site worse, so I stopped, deleted my account, and started CWing everything

there are still some things I do for which I'm not sure whether they help the site, though

like posting answers in A Pear Tree, which is so good at radiation-hardening it feels like cheating

but people seem to like the answers anyway, so maybe they're adding to the site even though they don't take much effort to write #HG9ade

Nobody

@ais523 wdym

ais523

@Nobody as an example, I once decided to repcap every day for a week

and it didn't take that much effort either

Nobody

what is repcap

ais523

06:55

from most sources, you cannot gain a total of more than 200 reputation in a day

Nobody

yah and?

oh

ais523

so if you gain 200 reputation in a day, that's called repcapping

Nobody

@ais523 where is it

@ais523 o ok

ais523

where is what?

Nobody

> well, the "zoom in on the Swedish flag" answer was incredibly funny, even if it broke the rules

Aiden Chow

06:56

@Nobody it was edited to zooming on an emoji iirc

Nobody

where is it

why not just print an emoji

Aiden Chow

71

A: Draw the Ukrainian Flag

HTML+SVG, 39 bytes <svg viewbox=12.5,-8.9,1.5,1><text>😴 The question forbids zooming in on the Ukraine flag... but not the flag of Sweden! Apparently that's disallowed too, so I'm using an emoji. This code is terrible practice and probably doesn't work on most browsers/OSes. It works on Firefo...

ais523

for what it's worth, I believe that CGCC's height of popularity came as a direct result of popularity-contest

Aiden Chow

@Nobody ^^

Nobody

what is that

ais523

06:57

it turns out that when you ask people to optimise for being popular, you get a lot of popular answers, and the resulting posts are very linkable to other sites and draw in a lot of visitors from elsewhere

Nobody

emoji?

> ^^

hyper-neutrino

^ is an up arrow so ^^ means the message two messages up

i've also seen ^^ used as an emoticon before though

Aiden Chow

bruh i never knew two up arrows could form an emoticon lol

ais523

↑ is a much better up arrow

…now I'm wondering why I memorised how to type that

it's probably for some esolang but I can't remember which

Aiden Chow

@ais523 agreed, except idk how to type that lol

Nobody

06:59

yah but hard t type

Aiden Chow

alt code ?

hyper-neutrino

for me it's right alt + y lol (since I have the APL keyboard still, for... some reason)

ais523

for me it is AltGr + Shift + U
