@quartata I've golfed packages down to pkgs

quartata

@Downgoat Uh, why?

Downgoat

@Quill is there a way to run fs.mkdir as sudo?

quartata

You could do modules or libs

Downgoat

@quartata why not?

Quill

@Downgoat no idea

quartata

01:00

@Downgoat You run sudo

Downgoat

@quartata I'll probably just call it cpmlibs

@quartata I wish it was that easy

quartata

@Downgoat That's redundant though

Downgoat

right now it just prompts the user to run cheesecloth with sudo

which is dumb

quartata

Well generally package managers need root...

But what I meant was you could do system("sudo mkdir /usr/share/cheesecloth")

Eᴀsᴛᴇʀʟʏ Iʀᴋ

727 manually

Maltysen

01:02

@EᴀsᴛᴇʀʟʏIʀᴋ 510 :P

Eᴀsᴛᴇʀʟʏ Iʀᴋ

not dead yet :(

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Now I'm trying to get the worst score

orlp

I think I got lucky on my first run

@CᴏɴᴏʀO'Bʀɪᴇɴ oh that's simple

Maltysen

@CᴏɴᴏʀO'Bʀɪᴇɴ hmmm. code-challenge?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

how many?

orlp

01:02

always go for the shallowest node

Cᴏɴᴏʀ O'Bʀɪᴇɴ

really?

orlp

(least deep)

El'endia Starman

I wonder if a KotH could be based off of this...

Maltysen

@CᴏɴᴏʀO'Bʀɪᴇɴ the shallower the node killed, the deeper the tree its parent creates

Downgoat

@quartata I think it's better to use a built-in command to make directories rather than joining strings to make commands to be evaled

quartata

01:03

Well, I assumed you were just creating cheesecloth

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Maltysen cool

quartata

But seriously, I don't know of any package manager that doesn't run as root (unless you're installing to .local/share)

Just throw an error if you aren't running as root (easy getuid)

Downgoat

@quartata no I'm creating directories to store packages

quartata

@Downgoat OK.

El'endia Starman

OOH OOH...would it be possible/feasible to create a KotH pair where one is for Hydras and the other is for Herculeses?

Maltysen

01:04

@El'endiaStarman like red team, blue team?

El'endia Starman

Something like that, yeah.

Maltysen

or you write two programs

and you play everyone twice

Downgoat

@quartata right now it throws:

An error occured creating the cpmlibs directory:
    EACCES
Perhaps attempt running this script with 'sudo'?

El'endia Starman

Splitting into two challenges allows people to write only one or the other. It'd be like a fusion of CnR and KotHs.

quartata

@Downgoat Perfect

Mars Ultor

01:06

@Maltysen Shallowest normal head? or just shallowest in general?

quartata

Wait, is that just the default error?

Maltysen

@El'endiaStarman sounds fun. now who wants to write the controllers? ;P

Downgoat

@quartata that's what it outputs if something returns a permission error

quartata

Oh, OK.

El'endia Starman

@Maltysen I can Sandbox them and explicitly say that anyone can execute the idea.

Geobits

01:09

Hmm. Is there a provably optimal strategy for either side? That might damper the koth idea, especially if it's not hard to implement.

El'endia Starman

Yeah, I was wondering that too.

It should be possible to devise some variant that allows for non-trivial strategy.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Well, manually finished (the whole way manual) in 1118.

i hate life

El'endia Starman

Title idea: Nobility and Peasantry of the Hill: Hydra vs Hercules

orlp

you guys are running away with my link?

yet no one starred it so other people can see it on the starboard :(

Alex A.

Stars are for important things, like "ROASTE D"

3

Geobits

01:12

I had to scroll to find out what they were talking about. It was horrible I tell ya.

El'endia Starman

@AlexA. I'm pretty sure that one was starred because of the special formatting. :P

Eᴀsᴛᴇʀʟʏ Iʀᴋ

fixed now

PhiNotPi

Did somebody say KOTH?

2

El'endia Starman

@orlp Well, I just starred it, but it's not showing up. :/

@PhiNotPi Yeah. CnR fusion with KotH for this.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

function step(){
	Array.from(document.querySelectorAll("#nodes > [class^='head']")).reduce((p, c) => p.y1.baseVal.value > c.y1.baseVal.value ? p : c).dispatchEvent(new MouseEvent('click', {
		'view': window,
		'bubbles': true,
		'cancelable': true
	  }));
}
setInterval(step, 5);

Worst-score program :D

Q: I'd like to say a [word] or two about this tag

We have a tag: word I see no value in this tag. Here's from the wiki: Use this tag for: Challenges involving generating words Challenges involving using words Challenges involving manipulating words Or other cases where words are a large part of the challenge. Do not...

Quill

[class^='head']

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@MarsUltor really? I'm intentionally trying to score poorly

@Quill what?

Quill

@CᴏɴᴏʀO'Bʀɪᴇɴ what's that for?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Quill it's a query selector

Quill

01:15

@CᴏɴᴏʀO'Bʀɪᴇɴ what does that selector do? I know what querySelector is

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Quill it looks for all elements that contain the word head

Quill

~~if you're looking for an element with class head, you can use .head: #nodes > .head~~ right, well, if the class only contains the word head, then that's okay

Eᴀsᴛᴇʀʟʏ Iʀᴋ

^

> 22018 head so far

@CᴏɴᴏʀO'Bʀɪᴇɴ noice program. :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

danke

Eᴀsᴛᴇʀʟʏ Iʀᴋ

no, no optimal strategy for hercules

markhkim.com/2013/10/killing-the-hydra

only good strategys

@CᴏɴᴏʀO'Bʀɪᴇɴ can you change your code to pick the top heads?

Mars Ultor

01:19

@CᴏɴᴏʀO'Bʀɪᴇɴ *starts with

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@EᴀsᴛᴇʀʟʏIʀᴋ sure. switch the > to a <.

@MarsUltor ah, right

Mars Ultor

$= is ends with, *= is contains

Cᴏɴᴏʀ O'Bʀɪᴇɴ

oh right

that makes sense, regex

Got it in 722 heads (top element)

609

Geobits

How have I been an SE member this damned long without figuring out how to vote on tag synonyms? Someone help.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

ALRIGHT bai

Geobits

01:22

Ok, nvm. Figured it out, and I just don't have the score necessary.

PhiNotPi

I completed it in <300 heads

El'endia Starman

@PhiNotPi Lucky you. 700-800 seems to be the manual average.

PhiNotPi

My strat: out of the deepest nodes, pick one with a brown neck if possible, else pick one with a green neck.

That being said, this is something where a single random event can add 100s to the count.

Q: Find a maximal rectangle

Background I want to buy an plot of land and build my house on it. My house should be rectangular, and as large as possible; however, the available plots have lots of rocky areas that I cannot build on, and I'm having trouble fitting a potential house on the plots. I want you to write a program ...

code-golf array-manipulation optimization

Alex A.

@Geobits I also don't know how .-.

Mars Ultor

01:28

> Hercules has cut 382147 heads so far.

orlp

is Gödel incompleteness theorem the most important result in math?

El'endia Starman

@PhiNotPi That does seem to be a good strategy. 210 heads!

Geobits

@AlexA. Go to the tag page for the target and hit the 'synonym' link. It takes you here, where you can vote on any proposed ones with teeny, tiny vote arrows.

El'endia Starman

@orlp Definitely one of the top three.

Alex A.

@Geobits Awesome, thanks!

It has 0 votes? o_O

Zgarb

01:30

@orlp Very likely, if by "important" you mean "overthrowing the very foundations of the field".

PhiNotPi

258 heads

Quill

I have a good strategy:

> Try not to get mad
Get very mad

Geobits

@AlexA. I tried, but I don't have the clout in that tag.

Quill

works every time

Alex A.

Oh right

PhiNotPi

01:32

@El'endiaStarman From what I can tell, this is similar to the proof that Ackermann's function always terminates: it's strictly decreasing by some kind of lexicographical order.

orlp

@Quill heh

2

Quill

that's a small rug and a large vacuum

Geobits

Well, he's doing everything naked, too, but sure. The small rug is the weird part.

Maltysen

@Geobits what're you talking about? he's wearing a tie in the first panel :P

El'endia Starman

Same strategy and I'm already at 244 heads and this just happened:

RRRG!

At least the particular tameness of this hydra will play into my favor now.

Downgoat

01:37

Can anyone running el captain run node -e "console.log(require('os').release())" and tell me the output?

El'endia Starman

Aaaand all dire necks eliminated.

At 329 heads cut off, the hydra is dead!

Still a good strategy, then.

orlp

@PhiNotPi that's what I did

Geobits

@Maltysen Plot twist: His only plan for the tie is as a noose.

Quill

310 that was a waste of my time

El'endia Starman

And yet, you couldn't help yourself.

Quill

01:42

answer by a new user:

1

A: 1, 2, Fizz, 4, Buzz

Javascript, 64 bytes for(i=0;++i<101;)console.log((i%5?'':'fizz')+(i%3?'':'buzz')||i)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

yeah

I reviewed.

Why is this being VTCed? the winning criterion is code-golf, as tagged?

Phrancis

@Quill lol FizzBuzz

Eᴀsᴛᴇʀʟʏ Iʀᴋ

?

@Phrancis can you write VBA in a text editor (e.g. notepad++) and run it?

Not write in the IDE?

Helka Homba

@EᴀsᴛᴇʀʟʏIʀᴋ Why not? its still just a text file

Eᴀsᴛᴇʀʟʏ Iʀᴋ

idk

but a fizz buzz answer said he couldn't shave off certain spacing because of the editor

Helka Homba

01:51

oh

Geobits

Surely you can turn off the auto-formatting though.

(just don't ask me how, unless you want a straight-from-google answer)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Anybody know of any programming classes designed for advanced (read: fluent in language) coders?

hopefully for python

Phrancis

@EᴀsᴛᴇʀʟʏIʀᴋ Good question, but I don't know the answer

Eᴀsᴛᴇʀʟʏ Iʀᴋ

okay

Phrancis

Also, just wrote this

declare @i int=1 while(@i<101)begin print case when @i%15=0 then 'FizzBuzz' when @i%3=0 then 'Fizz' when @i%5=0 then 'Buzz' else cast(@i as varchar(3)) end set @i+=1 end

Eᴀsᴛᴇʀʟʏ Iʀᴋ

01:54

Do you code VB well though?

read: golf well

Phrancis

169 bytes

@EᴀsᴛᴇʀʟʏIʀᴋ I code as little VB as I can help it

Eᴀsᴛᴇʀʟʏ Iʀᴋ

okai

Alex A.

@Phrancis garden hose

^ I just wrote that

Quill

@EᴀsᴛᴇʀʟʏIʀᴋ You're gonna be hard pressed to find one, you're probably better off doing whatever project pops into your mind or doing CS tutorials

Eᴀsᴛᴇʀʟʏ Iʀᴋ

I thought you were a VB person.

@Quill yeah

Helka Homba

01:56

@EᴀsᴛᴇʀʟʏIʀᴋ Loads of colleges like MIT and Harvard post their entire CS course material online nowadays. You could follow along with a course at your own pace.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

not my idea, apparently the powers that be in my life need proof of my programming skills but not golfed code... :(

@HelkaHomba ooh

Alex A.

Usually only intro CS courses use Python though

Or at least it seems that way

Eᴀsᴛᴇʀʟʏ Iʀᴋ

hm

what languages would they use for more advanced courses?

quartata

There's probably a data structures course in Python on the interwebs you could try. That would be a logical next step.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

R, C, ?

Alex A.

01:57

Java

Why would they use R in a computer science class?

Helka Homba

I think I used python for an upper level compilers course

Alex A.

I don't think CS degrees in the US teach C anymore

(I say, not having a CS degree)

PhiNotPi

My university uses Java and C++ mostly.

orlp

@AlexA. they do

Geobits

@AlexA. Do they even teach the S part? :P

orlp

01:58

or well

Maltysen

@AlexA. u serious? But what about all the low level algorithms?

orlp

often it's C++

but we used C for our system class

Geobits

@Maltysen I think they moved to Scratch for those.

Alex A.

Most of the programs I've seen use Java almost exclusively

Quill

@EᴀsᴛᴇʀʟʏIʀᴋ do a bunch of pretty looking Python projects or make a library or something if it's for a portfolio

Eᴀsᴛᴇʀʟʏ Iʀᴋ

01:59

no

Helka Homba

@AlexA. I did some C, even low level MIPS

Maltysen

@Geobits ._.

Quill

@AlexA. I can confirm this is false, I am learning C at the moment

Eᴀsᴛᴇʀʟʏ Iʀᴋ

for school, hopefully get out of "intro to what is computer" in public school next year

@AlexA. idk

why not?

Maltysen

@EᴀsᴛᴇʀʟʏIʀᴋ public schools are pretty nice with CS and allowing you to skip
