@HyperNeutrino definitely
 
@totallyhuman Mathematica, Roots
 
@Riker can I say hi now or busy?
 
@Blue Busy, playing games w/ brother
Sorry
 
Aww. Okies
 
@Riker ok i hammered bc I really think it's a dupe and if anyone disagrees they can fight me :p (mod pls no ban)
 
12:23 AM
@HyperNeutrino They are quite different: The old one's challenge was mapping to a non-sequential alphabet. This one's challenge was mapping two alphabets (i.e. try to combine it into one translation to save bytes).
 
Oh hm you actually have a very valid point there. I stand corrected. Thanks!
 
@HyperNeutrino Did we just both vote to reopen, or did I just unhammer?
 
I think you just unhammered.
 
@HyperNeutrino I didn't know that power. Wow.
 
Yeah, you can just directly unhammer my hammer. I think I'm not allowed to hammer it closed again at this point but I can't remember.
 
12:28 AM
You can't but someone else with a hammer can
 
But at that point it should go to meta?
 
yeah definitely
 
@DJMcMayhem Halp please explain tio.run/##S0oszvj/…
 
I just remembered an idea for a meta post i had: a post where people can post links to ppcg related challenges but which wouldn't work on main for unobjectivity or such e.g. the one team koth thingy i thought up, or some sort of writing generator challenge or such which requires judges
 
12:44 AM
We should have an answer to the 404 challenge with 404 languages. TIO supports 434, so there are plenty to choose from.
 
Can anyone tell me if this works? It should output 25 in less than a second. It's not working for me
Nevermind, I asked Suever to reboot the server
 
DestructibleLemon! Has he been gone, or am I just oblivious?

@ГригорийПерельман Solution: don't do that.
It's a known problem
in talk.tryitonline.net, Aug 11 '17 at 23:57, by Pavel
@Dennis You can't even read .output.tio without it borking: https://tio.run/##qyrO@P8/ObFEQS@/tKSgtESvJDP//38A
 
>_<
 
@betseg The way it works, it, essentially, there's a randomly generated magic string that .output.tio uses. It's used as a seperator between errors, debug, and regular output. Printing that magic string anywhere will cause it to break, obviously deleting it entirely will break.
Dennis is working on a fix, but it's a more long term goal.
 
1:23 AM
why was this deleted? Isn't this basically an optimal solution in HTML?
 
@betseg Yeah. You can reverse it locally to see what's inside .output.tio
 
k7yQ/UFyxXodPSM2 at that one
 
@betseg Well, it's random.
 
1:46 AM
so does this: Try it online!
 
@betseg I'm not gonna lie, I thought that was Pyth code at first
 
2:00 AM
@Pavel Uhhhhhh you got me there
 
2:44 AM
@Zacharý It's not a particularly massive polyglot challenge. The top three answers are collaborations of three users, so we wanted a chatroom to discuss additions instead of flooding the comments section
 
Ah, that makes sense. How many of you are actively posting in the behemoth?
 
None
I hate the behemoth
@Mego who's shinh on PPCG?
 
he's the guy who runs anagolf iirc
 
Ohh yeah I knew I recognized the name
 
3:03 AM
@MDXF Did you ever post one to the behemoth?
 
Four or five IIRC
Before it got to 100 though
 
The point I stopped caring enough to look at it is cckfck
 
hey
i have a problem
mafia KoTH i can't run it
I am locked out of my linux SU and i need SU to do the KoTH
can anyone help?
 
@Zacharý markdown bork
although cckfck is a better name
 
@Christopher2EZ4RTZ with breaking into your box, or finding another way to run the KoTH?
 
3:08 AM
@Οurous running the koth program
I just need someone with python 2
and PHP
I can send the directory
 
I think the linux boot on my laptop has both, I'll just check
 
kk
that has the entire setup
 
Solution: reinstall linux
 
does PHP version and subversion of py2 matter?
 
3:12 AM
no
 
I do indeed have php and py2
 
just do bash start

3:15 AM
it won't nuke anything outside the directory, right?
 
hmm. I need to move py2, it's trying to use my py3, few more minutes
 
@Christopher2EZ4RTZ not enough players
 
@Οurous uh oh
one sec
@Οurous pull from git again
wait nvm
yeah it is ready
 
3:28 AM
the.. uh.. git hasn't changed
 
opp
pushed it
 
@Christopher2EZ4RTZ it says 'player8', I think it's working?
yeah it still says player8. is it waiting for input?
ah yes
reads instructions in git
@Christopher2EZ4RTZ someone has an else if "You are the doctor" in line: causing a syntax error
continue anway?
and I'm also getting an EOFError: EOF when reading a line from opener = input()
@Christopher2EZ4RTZ since the bounty has 13 hours of grace left, I'm going to get lunch before I finish running this game - also, so you can respond re. the errors
 
4:03 AM
Tfw you work on a polyglot without paying attention to what you're doing and have to spend an hour fixing languages
 
4:14 AM
lol
 
4:36 AM
@Christopher2EZ4RTZ I'm kinda lost: 40% of the players regularly throw the same errors, and I don't know how well / what profile I'm supposed to play the placeholders like
 
4:48 AM
CMP: What should Cubically do when run with an empty program? Read a cube and print the moves to solve it is my first idea.
 
5:28 AM
Do nothing.
Is it possible to show up/down vote tally or show more comments from keyboard shortcut?
@NieDzejkob Same situation. We also have Logo in grade 4/5, and Pascal in grade 8.
@HyperNeutrino Just downgrade it. How can having more features be a problem?
 
5:56 AM
Glad to cause the torture
@MDXF Nothing, it's literally an empty cube
(0x0x0)

@EriktheOutgolfer can you check the sandbox for the image of latex?
 
1st one looks better but 2nd one fits in the middle of the sentence better
 
oh that's what you mean
well, those aren't technically images ;P
 
4:30 PM
Also, does anyone know if there is a way to 'lock' a class in Python i.e make it unable to call any methods or instances?
 
@cairdcoinheringaahing Hammers are great and do all things.
 
@cairdcoinheringaahing why would you want to do that?
 
@cairdcoinheringaahing # :P
 
@NieDzejkob So that the user cannot call any methods after something has been done e.g. call a certain method

4:33 PM
@MagicOctopusUrn Gesundheit.
 
@Mr.Xcoder I beg to disagree. If every closed post (except mods) needed 5 users to close it, then the post would actually be given a chance for users to decide whether it was a dupe or not, rather than have 8 people arguing about its dupeness, excluding the community from the decision.
 
I think that if someone hammers and the community opens, hammers should stop working on that question
 
the community always has the option to reopen / reclose it.
 
@Mr.Xcoder People have tried, but a user with a hammer has always been the first or second voter on that question. If we left it to those without hammers to decide, it would allow for some thought by the community.
 
4:37 PM
I flagged that for mod attention anyway a couple of hours ago, awaiting an action from a moderator
@cairdcoinheringaahing I don’t necessarily fully disagree, but you’re talking like gold badge users aren’t part of the community
 
@NieDzejkob The long story then. I'm making a language with functions that can be pushed to the stack. After the functions are called, they can remain on the stack, or in a register, but can still be modified (such as adding code). I'd rather not have dynamic functions, so I'd like to have a .disable() method, so that they can remain in memory but can't be modified or run again.
@Mr.Xcoder Sorry if it came off that way, of course I think everyone here is part of the community.
 
Ok :P
We need some mods to take action on that challenge, and preferably not just one of them.
 
I think having a proper discussion on Meta would be a great first step, and if it continues to be swing voted, temporarily lock it while sorting it all out.
 
Posting a meta question for a single challenge is not too suitable IMO
 
uh, there is the tag just for that
 
4:43 PM
@Mr.Xcoder It's been done countless times before
 
@cairdcoinheringaahing I don't know why you want to disable running a function, but you can always have a flag that prevents doing something
 
@EriktheOutgolfer Why would want to have that >_<
 
If this had happened, RIP Tetris GoL :/
@NieDzejkob Hmm, I'll have to settle with that. Thanks for the help!

@Mr.Xcoder Uh, to resolve issues pertaining to a single question?
 
or to be able to search for -[specific-question] :P
 
4:50 PM
Wouldn't it be better to generalise the question on meta to make it applicable for other challenges too?
 
the issue is the dispute, which has absolutely nothing to do with the challenge by itself, but is an issue of the challenge compared to other challenges

5:16 PM
Any ideas on how to make the question better? Specifically, is my specification for the output OK?
My post is just the "Extension of the Game of Sevens" listed above.
 
@WeijunZhou in the first example you have 1F as the end and you output it (it doesnt divide 7)
but in the second example you dont output 100 (it doesnt divide 3)
which one is correct?
 
The first one is correct. I will fix it.
 
can we take a moment to appreciate that this question has been hammered 8 times
 
I don't know that "appreciate" is the proper term. :-/
 
apprewhat
that's not a good thing...
 
5:28 PM
appreciate, "understand (a situation) fully; recognize the full implications of."
 
uh, I'd say it has connotations of "enjoying" what you "understand fully"
 
that's only one definition
it's not an uncommon definition or connotation...
 
I'd say it's the most common, especially in the context of the sentence you used.
"It's" meaning Erik's
 
@WeijunZhou I have edited your challenge. Feel free to edit / rollback.
 
@Mr.Xcoder hexadecimal
 
5:38 PM
Oh yeah >_<
 
Yes it's hexadecimal.
The edit is fine and thank you very much. It looks much better now.
 
I'll edit once again to make I/O flexible if you don't mind?
 
@AdmBorkBork regardless, it's still valid
 
True enough
 
only subject to misunderstandings, not necessarily false :P
 
5:42 PM
@WeijunZhou The pleasure is on my side! We try to be welcoming and to encourage new users to get involved :-)
 
I don't mind, just not too flexible.
[16,7,16,31] as input and [[1,0],[1,1],[1,2],[1,3],[1,4],[1,6],[1,8],[1,9],[1,10],[1,1‌​1],[1,13],[1,14],[‌​1,‌​15]] as output in the comment is valid
 
Yeah, believe me, people will not abuse it :)
 
@EriktheOutgolfer connotations are useless for validity :P
 
@Mr.Xcoder prepares to abuse it Sure... No-one...
:D
 
[16,7,[1,0],[1,15]] as input and [16,17,18,19,20,22,24,25,26,27,29,30,31] as output is fine
but not [16,7,16,31] as input and [16,17,18,19,20,22,24,25,26,27,29,30,31] as output
 
5:45 PM
@WeijunZhou You really don't have to worry about such things too much, we have some defaults for that and, while it is good to have a throughout description of input and output rules, don't worry too much about it :)
 
I see, thank you.
By the way are you still editing it?
 
Not right now. I have submitted my edits already.
 
@WeijunZhou you receive a notification if your post gets edited
 
I know that, but not if he is editing it...
 
well, the chance for two edits to collide is very small, and if you edit it while he's editing it he will be presented an additional restriction that his edit must be significantly different from yours in order to be submitted
 
5:50 PM
It's clear now. Thank you very much.
 
@WeijunZhou you don't need to thank answerers :)
you can simply upvote their answer
 
Well, maybe it's bad habit? I sometimes do so as well on other StackExchanges
 
@EriktheOutgolfer There was a time when we were new users too... I remember one of my comments on an 05ab1e answer: Done such a job in just 10 bytes... Impressive! or something... Your comment has made me very nostalgic :)
 
@WeijunZhou if you like an answer and it's useful to the question, you should upvote it, that's why the upvote button is there ;)
 
... That feel when you are trying to decide whether to use Pyth, Gaia, 05ab1e or Husk
 
5:55 PM
I always like seeing the "This is actually X bytes in UTF-8" followed by a heavily upvoted comment saying "Language uses a custom code page" :P
 
I always find those very annoying when there is a [bytes](link to the codepage!)....
 
For whatever reason, I often experience schadenfreude, so I find it amusing :P

it's still not aligned
 
@EriktheOutgolfer i cant randomly add spaces tho, it would look aligned in other fonts
 
Maybe you should add indentation and linefeeds to make it look like production code, then explain that?
 
makes sense, but how do i closure? i dont understand how they work :(
 
uh, indent like your code should if ungolfed?
 
@Mr.Xcoder Dang! Gaia is nearly unusable because you have to push lists separately, Pyth has input quirks for more than 3 inputs, 05ab1e is confusing when it comes to taking multiple inputs and I have problems with type inference in Husk :(
 
6:50 PM
@Mr.Xcoder CJam, obviously.
 
hi everyone
 
hi
 
is eval allowed in quines?
 
Definitely.
 
6:52 PM
@EsolangingFruit Too bad I don’t know CJam
@NieDzejkob As long as you don’t use it to read your source code, sure it is ok.
@LeakyNun Hi!
 
like s="do_something()";eval(s) instead of s="do_something()";do_something();

thank you
 
6:59 PM
@betseg Rev 7 of 8
 
@Mr.Xcoder CJam has excellent documentation, and there's not a whole lot of builtins.
 
@EsolangingFruit Hm I’ve searched for CJam’s docs in the past but never found them. Thanks! (Also, why the heck is it on sourceforge?)
 
@aditsu doesn't like GitHub?
 
sourceforge looks different?
 
I guess not (and I'm not a fan of SourceForge's new design), but I'm not downloading the source so I don't really care
 
7:02 PM
^^
I recall SourceForge as being horrible... Is it just me? Looks much cleaner now.
 
^
 
SourceForge's design is the least of its problems.
 
lol
 
In any case, there aren't ~200 builtins to memorize (only like 120) and it's all printable ASCII so you don't end up going on the docs too much
 
Yeah, but at least it tries to mask that a bit now (still not going to ever use it, though)
@EsolangingFruit Like Pyth for that matter
 
7:07 PM
Yeah, I've tried Pyth a little bit
I probably should use it
 
Now that CJam isn’t too competitive anymore, I am reluctant about learning it
Otherwise I definitely would, seems like a nice language
CMP: Which one would you learn if you had to choose between Retina, SOGL, Canvas and Charcoal?
 
charcoal
 
retina
@Mr.Xcoder What about V?
 
Charcoal because I need ideas to add to Canvas
 
@alicegoldfuss i once had the after-hours support pager for a unix supercomputer company in the early 90s. a call comes in at 6:30PM from NASA: "how do i exit vi?" - my response: "it's not rocket science." - his response: "i know. if it was rocket science i wouldn't have to call you."
@Mr.Xcoder Retina, so I can get better at regex
 
7:20 PM
@cairdcoinheringaahing that's correct, and I really don't like git in the first place

@EsolangingFruit Hm, it was more of a poll to see what I should try to learn, and as of now I don’t quite consider V as an option because I know nothing (and am not planning to learn in the near future) about Vim.
 
@dzaima you can also try to win this one

Here's some useless trivia: I ran a few queries across indexes of file systems of our customers (most of them have file servers with many dozens of TB of data). Pretty consistently, only between 20 and 30 percent of file names (including dir names) are unique for any given system.
