do you have a link to the prolog interpreter?
 
I tacked on a -join',' to the array slice to make output more clear
 
@TimmyD Oh, cool!
 
5:02 PM
run_from_atom is in brachylog.pl
 
@Bálint It's not rendering...
 
If you open the console with F12, does it say anything?
 
Syntax error, line 7.
It's the ES6 function, IE11 doesn't support them.
I'll use Firefox.
 
why were you using IE11...?
 
5:06 PM
^ this
 
@CᴏɴᴏʀO'Bʀɪᴇɴ See my profile.
 
@CᴏɴᴏʀO'Bʀɪᴇɴ It led me to somebody else too
 
Ditto
 
@wizzwizz4 That's not an excuse

IE11 is great and does all things.

for few values of "all things"
 
@TimmyD Like not working
 
@Bálint Actually, Microsoft have started releasing breaking changes to the browser...
 
5:08 PM
@wizzwizz4 -2
 
Timmy's message needs to be above mine so it reads nice on the starboard :p
 
@Bálint downgoat
 
@Bálint Works fine for me, must be a PICNIC issue.
 
@wizzwizz4 changes that break it? Go figure
 
@CᴏɴᴏʀO'Bʀɪᴇɴ It's so they can call Edge "the best browser they've ever made".
 
5:09 PM
that wouldn't be too hard
 
i mean they probably can just call it that now
 
They are breaking the best browser they ever made, so Edge will be better than it.
 
@CᴏɴᴏʀO'Bʀɪᴇɴ I wanted to say the same
 
I like Edge -- it's ridiculously speedy, for one -- but there are a couple oddities that have held me back.
 
Edge is Microsoft's solution to the incompatibility between backwards compatibility and browser standards. I think it's a pretty ingenious solution.
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Why do you have IE11 and Edge on the same line?
 
@TimmyD aren't they the same thing?
 
5:11 PM
@El'endiaStarman Yes, but the interface is bad, it relies on the Metro system that Microsoft haven't finished implementing yet, it has fewer features...
@CᴏɴᴏʀO'Bʀɪᴇɴ The engine in Edge is the IE14 engine, but apart from that... no.
 
Close enough™
microsoft likes skipping numbers ._. what happened to IE12,13?
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Engines in Edge.
 
@wizzwizz4 "Metro"? Good gravy, update your terminology.
 
@CᴏɴᴏʀO'Bʀɪᴇɴ What happene to windows 9?
 
@Bálint Yeah, ikr
 
5:13 PM
@Bálint Somebody else took the copyright. They didn't have enough money for a lawsuit, so they just skipped it.
 
@Bálint -._(._.)_.-
 
@zyabin101 ಠ_ಠ
 
5:15 PM
i think they did it so third party code wouldn't break if it checked for "Windows 9*"
 
@BusinessCat ಠ_ಠ
 
@CᴏɴᴏʀO'Bʀɪᴇɴ The actual reason is because Apple made so much money with OSX. they wanted to join the Version 10 party.
 
I'm currently translating a joke comic, give me 5 minutes
 
@Bálint Windows 9 was removed from the naming scheme to maintain backwards compatibility. There exists a bunch of software that ran different code paths if it was on Win95 or Win98 vs ME or 2000, and they checked against "Windows 9*" for the install.
 
I've heard that it was because 7 8 9
:p
 
5:16 PM
-_________-
 
@CᴏɴᴏʀO'Bʀɪᴇɴ 7 certainly tried to eat 8! 8 gave Windows a bad name.
 
@wizzwizz4 I like 8 :/
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Actually, it was, because 6 7 8.
 
I prefer Windows RG
 
I prefer Debian.
 
5:17 PM
@Poke Is that that Flash one?
 
@BusinessCat yerp
 
@BusinessCat Say, what kind of business are you in to?
 
"Really Good" edition
 
"Reconsider Getting"
 
@wizzwizz4 The engine in Edge is EdgeHTML, a fork of Trident ...
 
5:18 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ Pest control (specifically mice), catching the red dot, etc.
 
@TimmyD You mean "a rebranded version of Trident".
 
@BusinessCat Oh, how enlightening! :3
 
@wizzwizz4 Uh, OK then.
 
@TimmyD Because I am ranting. Ranty ranty rant. [Insert biased opinion here], [insert organisation name] is [insert offense here] because [insert conspiracy theory here].
 
Well, let's just call everything a rebrand of Mosaic and be done with it. :p
 
5:22 PM
Mosaic is just a rebranding of Tiles.

@Meanbits Oh hush.
 
@Geobits Snap out of it.
 
@Meanbits Meanbits, seriously?
 
@Geobits Be yourself again.
@Geobits Come on, be nice!
BE NICE!!!
 
5:26 PM
Why are you guys on about this twin thing again?
I'm clearly not who you think I am.
 
@Meanbits You are Geobits. Not Meanbits. Stop being mean.
 
Is Geobits not mean or something?
 
@Meanbits Good point.
 
I should tear off a brand new site, name myself Nicebits and become Geobits' nice daugther.
 
5:29 PM
I have no daughter.
Neither does he.
 
@zyabin101 s/nice/promiscuous/
ftfy
 
please this meta confusion is just too much
 
@Poke I should tear off a brand new site, name myself Promiscuousbits and become Geobits' promiscuous daugther.
 
MAYBE IT'S JUST ME but "Nicebits" sounds a little promiscuous
that's all i'm sayin'
 
It really does.
 
5:32 PM
oboy.
 
@RidiculouslyNicebits Oh dear.
 
But who am I to judge? That would be mean of me.
 
@RidiculouslyNicebits Holy ***.
 
That doesn't sound very nice.
 
5:35 PM
You changed your name.
 
@RidiculouslyNicebits Seriously
 
Nobody liked Meanbits, so...
 
@RidiculouslyNicebits So you think this is better
 
@RidiculouslyNicebits I like @RidiculouslyNicebits. So long as you can still moderate properly, it's fine.
 
@RidiculouslyNicebits You interrupted me with this.
 
5:36 PM
nah, what we really need is an Aquabits
 
@RidiculouslyNicebits Change to AbsolutelyRidiculouslyNotMeanBits
 
@Bálint I like to think so, but I'm a pretty nice person. Others may not see it that way.
 
Although, remove the @Ridiculously part. That's not very nice.
 
It'd be super effective against a Geobits
 
@RidiculouslyNicebits lol
 
5:37 PM
@NathanMerrill No can do. Aqua Tart might take offense :D
 
@NathanMerrill brb tearing off new site and changing name to Aquabits.

@RidiculouslyNicebits Electrobits then?
 
@RidiculouslyNicebits Who didn't like Meanbits??
 
@NathanMerrill That would have no effect though :/
 
5:38 PM
but Aqua Tart will take care of Geobits, and you can take care of Aqua Tart

@Meanbits You are Geobits. Not Meanbits. Stop being mean.
:(
 
@NewLoopholeProposal You posted! :D
 
or maybe we just do some Psybits
 
Everybody join the the Bits train!
 
> a Geobits
 
5:38 PM
@IrksomeBits Not you too!
 
@trichoplax Ikr, it should be the Geobits.
 
Eastern Bits or Irksome bits?
 
You are @Geobits. Stop being ¬Geobits.
 
@NewLoopholeProposal Thanks for helping buddy.
 
@IrksomeBits Dunno, but there's no space before bits, and it shouldn't be capitalized that way :P
@wizzwizz4 No
 
5:40 PM
@*Geo*bits Yes.
 
@wizzwizz4 "No"
 
@zyabin101 I'm trying to implement !i.:. What should !!!! yield?
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Nothing.
 
@wizzwizz4 That's not very persuasive.
 
! is double volume so !!!! should be 16 times as loud

5:42 PM
@zyabin101 Why? !!! is !! !!, so why isn't !!!! equal to !! !! !!?
 
People star the stupidest things. That's my excuse for saying them
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Moves right three.
 
@zyabin101 Sorry, I'm talking about tokenizing
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Shouldn't that be !!!! = !!! !!! = !! !! !! !!
 
5:43 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ !!!! moves right three.
 
@zyabin101 Okay, so it's parsed as !! !! !!?
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Yes.
 
@IrksomeBits ಠ_ಠ ಠ_ಠ ಠ_ಠ ಠ_ಠ ಠ_ಠ ಠ_ಠ ಠ_ಠ ಠ_ಠ
 
5:44 PM
why is everyone changing their names
 
People get bored.
@Cᴏɴᴏʀbits would know this.
 
I'm not sure two people count as "everyone" though.
 
This review/post. Not sure what to do.
sorta golfed, but definitely not fully golfed. idk
 
ಠ_ಠ
 
5:47 PM
this is pretty funny too:
 
I don't know, can you give an example of someone who hasn't changed their name?
@CᴏɴᴏʀO'Bʀɪᴇɴ Having now actually read the README, I would read !!!! as !! !! !! so I take back my earlier hastiness
 
I haven't heard of them
 
@trichoplax phews good to hear
 
@trichoplax o/
 
5:50 PM
Wow. I'm surrounded by people who stayed true to their original name.

@Dennis rekt
 
It's on Super User...
 
Lol I only just noticed it's a SuperUser post
 
@trichoplax raises hand OOOOO!
 
Downvote if you feel it's worth it.
 
@Dennis You have a reputation.... :P
 
5:53 PM
@Dennis maybe he thinks he's being clever
 
@Dennis Your reputation betrays you
 
@Dennis Where is that from exactly?

how do I interleave two lists in J? I want, say, 1 2 3 v _2 _3 => 1 _2 2 _3 3
 
@Dennis How difficult do you find it to remember not to golf answers on other sites?
 
The instant flood of downvotes would be a good reminder in most cases.
 
plus a single upvote from Olivier
 
6:03 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ I don't remember exactly, but you could try stitching them together with ,. or ,:, and then flattening with ,
 
But that won't work if they don't have the same length...
 
@Zgarb ,. gives a length error on arrays with different dimensions, and ,: leaves a trailing zero.
   ,|: 1 1 1 ,: 2 3
1 2 1 3 1 0
would it be safe to chop that off? it would remove crucial elements
 
@CᴏɴᴏʀO'Bʀɪᴇɴ You could chop off as many elements as their lenghts differ.
 
6:08 PM
Ohey ~rys
 
No wait, the zeroes are interleaved between the actual elements.
 
@CᴏɴᴏʀO'Bʀɪᴇɴ I had a good laugh on this. Especially on Martin Büttner's answer
 
@RenderSettings Just now noticed you there.
 
@Bálint yeah, it's pretty good
@Zgarb I feel like there's a builtin for this, but I guess not
 
@CᴏɴᴏʀO'Bʀɪᴇɴ How do you get a lot of reputation though? I really want to see these, and how much downvite and upvote an answer got
 
@Bálint Basically this. Learn this language, and you're set.

A: Shorten an already short mathematical expression

Cᴏɴᴏʀ O'BʀɪᴇɴEmotinomicon, 48 bytes / 13 characters I do it, not because it is short, but because it is fun. Try it here. You'll have to copy+paste it into the textbox. 😼⏪🆙😦✖😎😿➕😨😼🆙😄⏩ Explanation: 😼 ⏪ 🆙 😦 ✖ 😎 😿 ➕ 😼 🆙 😄 ⏩ explanation 😼 ...

 
@Bálint Just keep asking and answering questions. It happens over time.
 
for people very worried about my android/ipad problem.. I found a solution :)
 
@Lembik It was my camera solution, right?
 
@RidiculouslyNicebits similar
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Or I guess Unary
 
Unary could be made into a very short language, by only wiriting down the count of 0-s
everything could be solved in less than 8-10 bytes
 
I doubt that.
 
@CᴏɴᴏʀO'Bʀɪᴇɴ aha! Oration beat emotnomicon.
 
6:14 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ If your lists don't contain infinities, I think you can specify _ as a fill value to ,. by ,.!._ and remove the _ s from the final result with -.
 
Take this answer for example:
25
A: Just repeat yourself

MaltysenUnary, ~1.86 × 10222 Simple brainfuck -> unary answer. Very sub-optimal ;). The program consists of an even number of 0’s; specifically: 1859184544332157890058930014286871430407663071311497107104094967305277041316183368068453689248902193437218996388375178680482526116349347828767066983174362...

 
if anyone else asks a similar question please point them to me :)
 
@RidiculouslyNicebits How do you even convert a brainfuck program that long to unary?
 
You might want to ask someone who does that. I assume there are tools for this sort of thing out there, but I've never bothered looking.
 
The original program isn't that long - it's only long in unary

@RidiculouslyNicebits I was about to upvote the second comment when I had the jarring realization that I wrote it.

@RidiculouslyNicebits will you change your avatar when we get our shiny new voting buttons?
 
I haven't decided yet. I like this one's simplicity, but I need to see the new one to know for sure.
It also wouldn't make much sense on any site outside PPCG if it was something else :/
 
You can set your avatar per site, so you could use each site's downvote button
 
6:22 PM
@trichoplax True... but then chat-name shenanigans would change my avatar also :(

@El'endiaStarman As long as you can still eat it=)
 
@flawr Slowworm meat
 
6:23 PM
@Bálint You do? What kind of snake?
 
@flawr I show a picture, minute
Or lizard, I don't know actually
 
Haha, it's neither^^
 
^
Slowworm.
 
That's technically a lizard, right?
 
That's what I originally said
 
6:25 PM
That's what I mean
 
apparently yeah, according to wikipedia
 
@trichoplax Oh, true, I had the wrong notion that lizard was a more specific term.
Now I feel really strange, I never would have guessed that horse/rabbit meat isn't eaten that much elsewhere.
 
Rabbit meat isn't that uncommon in the UK, just most people don't
 
You can get horse in Japan, but it's a bit pricey IIRC. Not common though.
 
You used to be able to get very low price horsemeat in the UK, until they found out and took it out of economy "beef"burgers
 
6:28 PM
I might be wrong, but as far as I know it is cheaper than most of the beef here.
 
It was cheaper in the UK because it wasn't from animals bred for eating (with all the regulations that involves)
 
Oh that might be a reason.
How about sheep?
 
I think that's pretty universal
 
(No votes so far=)
 
I answered in terms of me personally - most people in the UK eat lamb/sheep sometimes
 
6:32 PM
@flawr I also eat chicken meat =)
 
Chicken isn't vegan??
 
It sure is vegan, it is basically carrots with wings.
 
@flawr This was an interesting read.
Apart from my aversion to trying new foods in general (I'm a picky eater), I wouldn't shy away from trying horse meat. I guess I just happened to not be influenced by that particular aspect of American culture.
 
if I owned a farm, I'd totally make my own burger fresh just to mess with Econ 101 classes
 
I'd give horse a try.
Rabbit is pretty tasty. Just don't eat only rabbit

Eᴀsᴛᴇʀʟʏ IʀᴋDo not repeat yourself meta-golf Given a number m, output a program that prints out the string Do not repeat yourself. Now for the challenging part: Each program the original code prints out has to have the byte at place m*n be the same as m*n - 1 and the same as m*n - 2 .... all the way down ...

 
@El'endiaStarman Thanks, that provides a nice insight!
Independent of the content this was by far my favourite part "With politicians strongly motivated to do nothing (...)" I feel like this is quite a common trait among politicians^^
 
Hahaha, that was funny.
Although, I don't think that situation is common. It's much more common for politicians to be apathetic. This is politicians purposefully doing nothing to avoid more ire and backlash.
 
@Zgarb Ooo, nice
 
@CᴏɴᴏʀO'Bʀɪᴇɴ How do you create an explanation for emotinomicon?

That would make it a fair bit less
 
@Bálint Wingdings?
 
@Bálint elaborate?
 
6:49 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ HM?
 
what do you mean by "part of the stack"?
 
If I put the code for a "," on the bottom of the stack, and I put things on it, can I somehow copy that to the top of the stack?
I could always reverse the stack though
 
do that, I don't think there's another way
BTW you an capture a string and use its ASCII code
 
Yea, that's a lot better
 
@Bálint wat
