Yay! Detour now has turbo mode!
 
My girlfriend's theory is that PETA is a sham organization set up by the meat industry to make the public hate vegetarians.
 
@Geobits it was a while back
 
@AlexA. This makes sense.
 
Hating vegetarians for PETA is dumb, though. Kinda like hating Texas for Ted Cruz.
 
I totally hate Texas because of Ted Cruz. (lel i kid)
 
3:02 AM
Don't you mean:
> Hating vegetarians for PETA is dumb, though. Kinda like hating America for Texas.
 
That works too ;)
 
@Doᴡɴɢᴏᴀᴛ Yeah, I knew that... I just didn't know JS had such wide Unicode support for variable names
m=ಠ_ಠ=>$(ಠ_ಠ)-1
^ meme, jQuery, downvote, golfiness. Need I add more?
 
No, but must s/\$//
 
@AlexA. So PETA is like a straw man? Interesting theory. Stranger things have happened in the food industry :P
 
¯\_(ツ)_/¯
It sounds super conspiracy theorist-y but I honestly wouldn't be surprised if it were true
 
3:08 AM
@ETHproductions needs perl
 
I'd be surprised. PETA has that ring of authentic assholery that you can't easily fake.
"The greater good" mentality and all that crap.

Anyone know the BF compressor that results in the shortest output for a given input string?

The "hello world" example program now compiles to a 896941-byte executable, thanks to libraries.
 
@Dennis Didn't he just do HW? I mean, I have a string and I want to convert it into the shortest BF code possible.
 
Yeah, use primo
Apply primo to affected area

google copy sh brainfuck generator. too lazy to get a link.
 
I mean, copy.sh isn't bad, but for HW, it's 128 : 81.
 
there we go
I think it was actually made by a PPCG user
 
For my input text it has a ratio of 1:11, which isn't bad
@quartata I've seen copy around

Q: Brainfuck Golfer

JiminPOne of easiest code written by a programming language is a program printing sequence of characters (ex. "Hello, world!"). However, some esoteric programming languages like Brainfuck, even this simplest code is quite annoying to write. Your task is to write a program (don't have to written in bra...

hey, what tools do you guys use for software designm?
I'm stuck on how a particular feature on my personal project should work
so I'm looking for recommendations on helping me think it through

Brains
 
where do you find those? I burnt my last one.
 
I usually just order them Amazon. They'd probably cheaper on ebay or something like that though.
 
do they come in 2 packs? I would want a backup
 
My last message seems to be missing some words. Maybe time for a replacement.
 
@NathanMerrill You can get a whole bag:

Q: Calculate the Cross Product

MaltysenThis challenge is very simple and I'm surprised that it hasn't been done before. You just have to calculate the cross product of two 3D input vectors. The formula for the cross product is given by: a x b = (a2*b3 - a3*b2)i + (a3*b1 - a1*b3)j + (a1*b2 - a2*b1)k where <a1, a2, a3> and <b1, b2, b3>

 
oooh, there are detachable parts!
I could replace my creative side with another logic module
then I'd definitely be a pure vulcan
 
3:36 AM
@ETHproductions Bruh you've seen ESMin.
 
You might need that creative side for software design, though.
 
yeah, that's why detachable is great
I can just stick it back in
 
Anonymous
@Geobits Only for getting through interviews. Then you can safely turn it off. Employers only pretend that they want creativity.
 
Oh, well sure if it's for an employer.
 
well, until I get that ordered, any recommendations for software design tools?
otherwise its the top result on google
 
3:40 AM
What is a "software design tool" even supposed to do?

There's always a way to get it from the SEDE. The issue then is that you have to use the SEDE to get it.
 
count distinct(Id) from Posts where PostTypeId = 1 and DeletionDate is NULL group by CAST(CreationDate as date)
That'll get the number of questions posted each day (untested)
Use it as a subquery, do AVG and get the average q/d

That's pretty far from valid sql
 
It actually isn't...
 
The inconsistent casing is beautiful either way.

1. It would need to be a SELECT clause.
2. COUNT(DISTINCT ...)
 
Advanced SQL programmers only shout the most important parts of the instructions to make sure the computer is extra careful to get them right.

Bugs are good. They tell us that we're human and made mistakes. A lack of bugs is bad, because that either means we've hit the Skeetularity or we made mistakes so bad that they're not even noticeable.

It's normal that in any code challenge or KOTH, someone will post an initial attempt involving minimal sophistication or effort.

Kind of like brainfuck in the way that it uses only a few symbols but it won't ever win a code-golf
 
@Doᴡɴɢᴏᴀᴛ We had a brief discussion about this (I still have to write up a meta post about it) which starts here:
Jan 16 at 21:16, by Dennis
@TanMath In a code golf competition, what is the point of taking an answer in one language and apply an encoding for the sole purpose or making it longer? On top of that, you haven't attributed the answer you encoded, in violation of our terms of service.
 
5:34 AM
@Dennis So are one-time joke esolangs (like Unicorn) are okay?
 
There's no consensus yet. My personal opinion is that encodings of a language (Unary for BF, Unicorn for ES6, etc.) should not be used to achieve a worse score.
 
Anonymous
Agreed
 
Anonymous
I'm also not a fan of the shortened-X languages, but I suppose they're technically valid
 
Of course, if the challenge is not a code golf, Unary or Unicorn might actually achieve a better score.

I just dislike code that is "I took this answer and applied a trivial transformation on it"
 
5:40 AM
What do you mean by shortened-X language?
 
@Dennis I'm assuming something like (example) BF with all of its char combinations shortened down to 1 char?
So +> would shorten to a or something like that.
I think?

@ՊՓԼՃՐՊՃՈԲՍԼ Wasn't it just purely shortened JS when you first created it?
 
@Mego In defense for JS golfing langs. I'd say now they're as close to JS as Pyth is to Python imo
 
@Mego Not quite. I wanted more than that.
Hence the blocks for compression (obfuscation), copy-paste, etc.
 
Anonymous
@Doᴡɴɢᴏᴀᴛ TeaScript and ESMin are about the only ones you can argue that for. Japt, Jolf, and JavaScript Function Golf are literally just shortened syntax.
