TeX, 304 bytes \documentclass[9pt,a4paper]{article}\pagestyle{empty}\begin{document}\count0=0\count1=0\count3=3\count5=5\loop\advance\count1 by1\count0=0 \ifnum\count1=\count3 Fizz\advance\count3 by3\count0=1\fi\ifnum\count1=\count5 Buzz\advance\count5 by5\count0=1\fi\the\count1 \ifnum\count1<1...

I would compare it to javascript where semicolon are both necessary and unnecessary

and I still haven't figured out how the expressions in TeX are parsed

Zacharý

Is that what would be considered a "onebox"?

Leaky Nun

@Zacharý yes

Zacharý

I've heard people say "don't onebox"

... One does not simply ... outgolf Dennis ...

@Zacharý sorry trying to get rid of the spam and made more

Zacharý

@StepHen Does editing re-notify you? ?

Q: How many states do I border?

When I was younger, I had a big map of the US tacked up on my wall across from my bed. When I was bored, I would stare at that map and think about stuff. Stuff like the four-color-theorem, or which state bordered the most other states. To save younger me some brainpower in counting, you are going...

Zacharý

Okay then, stop edit spamming me.

CMC: compute all factorizations of a number, e.g. 4=>[[4],[2,2]], 5=>[[5]].

Step Hen

@Zacharý shouldn't that be [[5, 1]]?

and [[4, 1],[2, 2]]

Zacharý

00:26

No ones.

Step Hen

@Zacharý crap that eliminates the mathematica builtin

Zacharý

Is there a challenge like that? (When I add the extension command to MY, that will be one of the commands, which won't be for a WHILE)

Step Hen

@Zacharý different output format, but basically the same (at least answer-wise): codegolf.stackexchange.com/q/104590/65836

actually that's prime factors, not all factors (although yours isn't all factors either because of no ones)

Zacharý

Should I post this on main?

Step Hen

@Zacharý you probably could

get some bigger test cases first though

and make sure 1 is in the test cases or eliminated from the input domain

Zacharý

00:33

Like this? 20=>[[20],[2,10],[2,2,5],[4,5]]?

Step Hen

and I mean like 6 or 7 characters long

Zacharý

I've got a horrible APL solution that runs so slow that 20 won't run on TryAPL: {∪L/⍨⍵=×/¨L←1~⍨¨,⍳⍵/⍨⌈2⍟⍵}

Step Hen

@Zacharý would the factor sets have to be sorted smallest->largest like yours are?

Zacharý

No order required.

Step Hen

and I mean like 6 or 7 digits long (maybe find a longish prime and a longish perfect number)

@Zacharý maybe a test case like 40340 - one of the last abundant numbers that fits on OEIS

@DJMcMayhem the prophet has spoken...

Zacharý

00:42

... too large ...

Step Hen

@Zacharý for your program or for a testcase?

Zacharý

Both,

ASCII-only

@LeakyNun this is me literally all the time

Conor O'Brien

does anyone know jelly decently in here

2EZ 4RTZ

@StepHen I wasn't on...

DJMcMayhem

00:44

@ConorO'Brien Decently-ish

Zacharý

Just look at the wiki, that's how you do Jelly.

Step Hen

@ConorO'Brien I know how to Ctrl-F keywords...

Conor O'Brien

let's say I've made a list, and I want to remove all instances of the two inputs from that list. how might I do that?

I tried ,ḟ and that didn't seem to work

ASCII-only

@ConorO'Brien ~~yes~~ nobody really knows Jelly decently :P

Conor O'Brien

@ASCII-only I suppose

DJMcMayhem

00:45

@ConorO'Brien So, a list of tuples, remove any instance of the inputs joined into a tuple?

ASCII-only

@ConorO'Brien link pls?

Zacharý

Posted on main.

Conor O'Brien

@DJMcMayhem I think so. jelly concats my list together so idk

ASCII-only

@ConorO'Brien don't they both need to be a list of tuples first

Conor O'Brien

I'm copying and pasting commands and hoping for the best

DJMcMayhem

00:49

@ConorO'Brien Could I have a TIO link?

Conor O'Brien

ok, gimme a sec I think I broke it

ASCII-only

@ConorO'Brien you probably need to W (wrap) the input tuple

Zacharý

Jelly output methods ... blech!!

ASCII-only

@Zacharý ?

Q: Total Factorization

The challenge Given positive integer input n (n>1), calculate the array of unique factorizations of n, not including 1. Order does not matter. Test cases 2 => [[2]] 3 => [[3]] 4 => [[4],[2,2]] 5 => [[5]] 6 => [[6],[2,3]] 7 => [[7]] 8 => [[8]] 9 => [[9],[3,3]] 10 => [[10],[2,5]] 11 => [[11]] 12 =>

@ConorO'Brien Here?

DJMcMayhem

Do we have a regex metagolf challenge yet? (Ala xkcd)

Zacharý

01:02

link to this xkcd?

Conor O'Brien

@ASCII-only yeah that works. too long tho, oh well

ASCII-only

How long did you want it to be

Conor O'Brien

basically under 5 bytes

>.>

ASCII-only

:/

Step Hen

@ConorO'Brien Actually, Seriously... and now you want Basically?

Conor O'Brien

01:04

no I really don't

A ~~nime~~ ctually was a mistake </s>

Zacharý

@ConorO'Brien FINALLY SOMEONE AGREES!

Conor O'Brien

o_O

ASCII-only

@ConorO'Brien why do you have an extraneous end strikethrough tag there

Conor O'Brien

it's a sarcasm tag

Step Hen

@ASCII-only ... /s indicates sarcasm

ASCII-only

01:08

@StepHen but it's in angle brackets

Noooooo it almost worked but it didn't

Downgoat

@ASCII-only ?

Step Hen

@Downgoat [tag:/s]

Downgoat

btw i started on LLIR and working on algebraically doing graph optimize

ASCII-only

Yay

Also: is ><> just >_> with beak

Downgoat

But need help because we're gonna have to write a lot of basic algebra 101 rules

Zacharý

01:12

><> is a FISH!!!!

DJMcMayhem

/bu|[rn]t|[coy]e|[mtg]a|j|iso|n[hl]|[ae]d|lev|sh|[lnd]i|[po]o|ls/ matches the last names of elected US presidents but not their opponents.

Step Hen

@DJMcMayhem hm sounds interesting (I'm assuming you mean the second panel)

Downgoat

Meta regex golf would be interesting test battery challenge

DJMcMayhem

@StepHen I was thinking the infinite one, but now that I think about it, your idea is much better.

:P

Step Hen

@DJMcMayhem yeah I'm thinking the same thing as @Downgoat - something like test-battery

Conor O'Brien

01:17

@DJMcMayhem hey I have a matl question. I'm trying to get matl to run locally with octave on windows. every time I run octave from the command line, it opens up a new console. do you know how I might avoid this?

DJMcMayhem

I've never run it locally, even once lol

Zacharý

c, HUH? That doesn't work on Sandbox.

Step Hen

@ConorO'Brien write a script to close the newest console whenever you run octave

Conor O'Brien

@StepHen right but then I can't retrieve the result...

@DJMcMayhem alright, thanks anyway

Step Hen

@ConorO'Brien uh close the second newest then

ASCII-only

01:21

@Downgoat ok

Conor O'Brien

maybe I'm not making myself entirely clear. When I run octave --eval "disp(32)", it closes the active console, makes a new one, displays the result, then closes that one as well

ASCII-only

@ConorO'Brien -W?

Conor O'Brien

nope

ASCII-only

--persist?

Conor O'Brien

produces a segfault

DJMcMayhem

01:24

@ConorO'Brien @LuisMendo Any idea how to fix this?

ASCII-only

@ConorO'Brien ok wat

Conor O'Brien

@DJMcMayhem oh wait I think I got it. apparently the windows install for octave calls a wrapper function around the raw exe. I just have to call the exe instead of the wrapper

Qwerp-Derp

01:36

Clojure is a nice lang, but it's really painful for anything outside of writing basic command line apps (with the exception of CLJS)

Which is a shame

Server-side CLJ is just cancer, probably due to the fact that it has to wrap around Java

ASCII-only

@Qwerp-Derp this is why node is the best :P

Qwerp-Derp

01:55

@ASCII-only Eww node is even worse

10 libraries just to start off

Express, FS, React, etc.

Step Hen

@Qwerp-Derp but at least it can do STDIN in JavaScript...

Qwerp-Derp

None of the libraries work well together

The ecosystem is pretty crappy IMO

@StepHen What use would that have?

Step Hen

@Qwerp-Derp online interpreters for programming languages :P

Qwerp-Derp

Ehhhhhhhh

Sinatra = best backend :P

Kemal = Sinatra on Crystal = better backend than Sinatra :P

ASCII-only

02:20

@Qwerp-Derp what no

Nick Clifford

Crystal is great!

ASCII-only

@Qwerp-Derp then don't use them?

Qwerp-Derp

@NickClifford :D

@ASCII-only Don't use libraries?

ASCII-only

Exactly

Qwerp-Derp

LOL this is JS, you can't not use libraries

ASCII-only

02:21

They're like jQuery

Makes most things easier but usually unnecessary overhead

Qwerp-Derp

Have you ever written JS without using a library?

DOM manipulation without JQuery is super painful

Zacharý

not-enough-jquery

Qwerp-Derp

Good luck trying to make a server without Express

Nick Clifford

ES6+ makes things better, but it's still kind of a pain

Zacharý

You technically can't do IO in Javascript >_<

Nick Clifford

02:29

can you guys give me some tips on anything I should try to change/improve on with Ohm v2 before I publish it to master?

Downgoat

03:21

@Zacharý wha???

@Qwerp-Derp this is actually pretty simple

@NickClifford looks like you're missing the goat built in :P

Nick Clifford

@Downgoat wow. I can't believe I forgot that. completely unusable without the goat builtin

ASCII-only

@Qwerp-Derp wth no

Just look at zquery

@NickClifford precisely

Nick Clifford

(but actually though does it look ok?)

ASCII-only

03:37

even Charcoal has it

Nick Clifford

is that the canonical ASCII goat?

Downgoat

@Qwerp-Derp if it was 2003 I'd agree with you but other wise not at all

ASCII-only

@NickClifford I think so :P @Downgoat can you confirm

Downgoat

@NickClifford yes

github.com/turbo/zQuery/blob/master/README.md

Qwerp-Derp

@Downgoat What about DOM manip using vanilla JS?

@ASCII-only Link?

NVM

ASCII-only

03:40

@Qwerp-Derp ...

@Qwerp-Derp ......

Qwerp-Derp

OMG I said "NVM" at the end... calm your farm

Nick Clifford

document.querySelectorAll is your friend

ASCII-only

@Qwerp-Derp node version manager?

Qwerp-Derp

@ASCII-only ....................

ASCII-only

@Qwerp-Derp yeah but seriously pls read first geez

@NickClifford also querySelector if you're using an id

Nick Clifford

03:42

right

Downgoat

Also bind operator is amazing for DOM iteratjon

Qwerp-Derp

Oh, did not know that, cool

Read through the zQuery thing, and it's cool

But I would still use jQuery :P

Nick Clifford

03:57

@ASCII-only @Downgoat github.com/nickbclifford/Ohm/commit/…

Qwerp-Derp

IMO JS's random stuff like document.getElementById doesn't match up with the rest of the language

Nick Clifford

then you have things like how giving a DOM element an ID (<div id="hi">hello</div>) creates a global variable (hi.textValue === 'hello')

Qwerp-Derp

And hoisting's a pain :P

IMO Ruby and Crystal > JS in syntax, but usability-wise JS is probs better (more libraries = more support I guess)

ATaco

JS is horrible, But I don't hate JS.

Much like Lua, it's horrible, but I love it.

Downgoat

@ATaco the similarities between JS and alcohol don't end :P

ATaco

04:13

Any noun probably has both an Alcohol brand and a JS library named after it.

Qwerp-Derp

The main thing I don't like about JS is its syntax, and for me syntax makes or breaks a language (I think this might be a bad approach to programming, but I like to program in languages that make me not want to strangle myself while working with its syntax)

ASCII-only

@Qwerp-Derp to slow down the page and waste clients' bandwidth?

@Qwerp-Derp ... JS syntax is C syntax

Qwerp-Derp

@ASCII-only See my point above

ASCII-only

@Qwerp-Derp ... How

Qwerp-Derp

With weird things that you have to watch out for

ASCII-only

04:18

@Qwerp-Derp like?

Qwerp-Derp

@ASCII-only It just doesn't match, you have your nice and easy things like function, var, for and while and bam, document.getElementByClass!

@ASCII-only Hoisting, === instead of ==, super weak typing

ASCII-only

@Qwerp-Derp eww lol end isn't better than braces to me

Qwerp-Derp

@ASCII-only I like end instead of braces, it seems cleaner

ASCII-only

@Qwerp-Derp ... Obviously? Why would DOM manipulation be a language feature?

@Qwerp-Derp how exactly

Qwerp-Derp

@ASCII-only IDK, it just seems cleaner to me

ASCII-only

04:21

I really don't see the difference lol

Qwerp-Derp

@ASCII-only ??? So you think it would be better to place it in a module? BUT WAIT! JS doesn't have a module system!

ASCII-only

It's like 3 char braces

@Qwerp-Derp uh what

Qwerp-Derp

JS = one-file philosophy :p

ASCII-only

@Qwerp-Derp ... Who said that

You have jQuery + your own code = 2 files

Qwerp-Derp

@ASCII-only I mean like all of the code that the programmer writes that isn't a library

ASCII-only

04:23

@Qwerp-Derp when did I say that, it wouldn't make sense as a language feature so it's a method on the document node

Qwerp-Derp

sigh fine

ASCII-only

@Qwerp-Derp well of course, normally you don't run a large project on a webpage

Qwerp-Derp

@ASCII-only But wouldn't it be better to separate your code into separate pages?

ASCII-only

@Qwerp-Derp idk, what do you mean

Qwerp-Derp

files*

Not pages

ASCII-only

04:25

@Qwerp-Derp it's like saying ruby print should be part of they syntax not a function

@Qwerp-Derp yeah? That's what I do with my JS

Qwerp-Derp

@ASCII-only Webpage JS or Node?

ASCII-only

@Qwerp-Derp webpage JS

Well node as well of course :P

Qwerp-Derp

Using a library, I'm assuming?

Or multiple <script> tags?

ASCII-only

@Qwerp-Derp how else

Qwerp-Derp

@ASCII-only But wouldn't it be better to have just one <script> and using a proper module library?

ASCII-only

04:28

Yeah?

Qwerp-Derp

But JS doesn't have modules

ASCII-only

It's called webpack/browserify/a lot of other things

Qwerp-Derp

@ASCII-only Those aren't really modules

And they're external libraries

ASCII-only

05:15

@Qwerp-Derp how.

@Qwerp-Derp you don't use them directly on the webpage though

Qwerp-Derp

05:31

@ASCII-only Don't you have to wrap your entire code with a require statement, and there's limitations compared to actual modules?

ASCII-only

@Qwerp-Derp Limitations?

Qwerp-Derp

@ASCII-only ??? How does that detract from the fact that it's an external library

ASCII-only

@Qwerp-Derp Well the compiler does that for you doesn't it

@Qwerp-Derp Nothing?

But seriously? JS was never meant to be modular

Do you think Brendan Eich could imagine what JS would be used for in the two (?) weeks he took to program it :P

Qwerp-Derp

@ASCII-only Yeah, I see your points

I just don't like JS as much as something as Ruby

ASCII-only

Of course :P if you're programming in a browser though you're either crazy or have no choice

Qwerp-Derp

05:35

What about CoffeeScript? :P

ASCII-only

Makes no difference if it's still in a browser

Qwerp-Derp

Syntax-wise, not performance-wise

Because CS compiles into JS anyway

ASCII-only

@Qwerp-Derp IDK, personally JS is fine to me, but if you're not a fan of C-based languages then CoffeeScript is probably a better alternative

Qwerp-Derp

I have these two equations:

2b - 2x + 3y = 0
y >= 56

Is there a way to create an inequality with only b and x by substituting y in?

I've tried this, but I'm not sure if there's anything wrong with it:

2b - 2x = -3y
2x - 2b = 3y
2x - 2b >= 168
x - b = 84

officialaimm

@Qwerp-Derp I think that would depend upon constraints of b and x, are they always positive or can they be negative?

Qwerp-Derp

b and x are always positive

officialaimm

I got to b>=28

Qwerp-Derp

Wait what

ASCII-only

07:43

@Qwerp-Derp *>= 84

@officialaimm You can't

@DJMcMayhem I'm only used to using Octave through the GUI. But it seems Conor solved it

Zacharý

Yeah, JS has no IO in its specification.

Perl is <insert language here> done wrong

ASCII-only

@Zacharý well it wasn't meant to be commandline so...

@Zacharý ... How

Zacharý

Perl is just confusing as hell.

ASCII-only

12:43

@Zacharý what why

Zacharý

@ASCII-only You can have grammars which barely work, things are referred to by natural language terms (one reason I don't use J), those stupid sigils, operators can be squeezed in between precedences, usage of things like x as an operator, circumfix reductioh, ...

ASCII-only

@Zacharý also you can just avoid them

Zacharý

I'm assuming you use Perl?

ASCII-only

Like most people do

Zacharý

@ASCII-only What is "them" that you are referring to?

totallyhuman

12:49

@ASCII-only i'm aware of that, i accidentally made everything floats

i'm not gonna fix it

ASCII-only

@Zacharý kinda? Not for a project though

@totallyhuman doesn't that mean it's nowhere near golfy anymore

Mr. Xcoder

@ASCII-only ಠ_ಠ

ASCII-only

@Zacharý okay not all of them but sigils aren't that bad, and x is fine if you make it clear for using it as an operator

totallyhuman

@ASCII-only it never was but how does this affect golfiness?

ohh you wanna answer the square challenge?

Zacharý

@ASCII-only Still unclear what "not all of them" is referring to.

totallyhuman

my advice: give up on commata :P
