The Nineteenth Byte

@CameronAavik I understand that, but a) many mathematical facts are stated in these challenges since math knowledge is not a prerequisite for these puzzles; and b) it's not obvious that when a knave says p => q it implies p, since p => q can be also be false for ~p universes (e.g., "If helium is lighter than hydrogen, hydrogen floats on top of helium" is a false p=>q statement where ~p).

Give me an interesting disapproval face that does not use markdown.

@Dennis According to the cheat sheet t is set but it doesn't seem to do what I thought it would. What does it do?

@CᴏɴᴏʀO'Bʀɪᴇɴ I'm not sure exactly what that is, but it doesn't look disapproving. More like smartass-mischievous.

@Geobits yup. could not resist.

[0 0 0]1 4t sets the element at index 1 to 4, so it returns [0 4 0].

Oh.

Ohhh

I thought it was literally set(<array>) (like in Python)

4:36 PM

CJam doesn't have sets.

Hm. I can't think of a good way to pull this off.

I need to get the indices of all non-unique elements in this array.

I thought maybe map count + logical not, then just find the zeroes.

@CᴏɴᴏʀO'Bʀɪᴇɴ 𝄑_𝄑

But that seems too long

Find index only returns one index at a time, correct?

too bad

Array.

Yep. That's it.

I always forget that I have the Commander Keen downvote userscript on my laptop. Catches me by surprise every single time.

two more holes

5:11 PM

(best viewed in that size)

I need this

I just added gotoes to my in-progress language design

It still needs conditionals though

Neal Stephenson thinks it's cute to name his labels 'dengo'

There are languages where gotoes and conditionals are the only forms of control flow

Underneath, all languages have gotos and conditionals as the only form of control flow...

5:14 PM

Also gotos are not bad and never were. Irresponsible programmers are the problem.

Wait a sec- since I have gotoex as well as goto, I don't really need conditionals. But they're probably be a good idea anyway.

and suddenly my little map trick doesn't work anymore

It doesn't work with strings.

Great.

I should still add that append method to the string type

@Dennis Does count not work with strings?

It does.

You mean e=, right?

5:17 PM

Yeah.

I'm doing :U{Ue=(!}%

It's probably Java string equality stuff

That should work perfectly. CJam doesn't use Java's strings.

It appears to work for integers just fine and characters just fine but not strings

cjam.tryitonline.net/…

Oh, do you have an array of strings?

Yeah.

In that case, you need :U{U\e=(!}%.

5:20 PM

:U reminds me of alex.

Why the \?

The syntax is <haystack><needle>e=. You can swap it if the needle isn't an iterable.

Ahhhhh

OK. Gotcha.

Where does a question about GitHub for Windows' problems with .gitignore belong: Superuser or SO?

superuser

5:22 PM

Stack Overflow

^

...

why?

git is a standalone application

@Liam Not git. GitHub - the software.

5:23 PM

Stack Overflow is suitable for tools commonly used by programmers, and Git is such a tool.

ahhh

github even more so than just git

Dammit this works but I just realized the challenge only asks for two indices

which is just weird

if you have git issues, they might be on topic on un*x./linux.se

whatever I'll post it anyways

5:25 PM

@Liam Not git. GitHub for Windows. git works just fine on it's own.

Because, y'know, windows.

I know. But if you're using a git prompt on windows (comes with the github application) it is pretty much the same thing.

and at the end of the day, most of the time when people have issues with GitHub, it is really git they are struggling with

A: Sandbox for Proposed Challenges

@Liam No it's not all the same. Private repositories require you to exchange your SSH keys with github when using the git bash. The desktop client uses the GitHub API for authentication. I also don't have any issues with Github as a service, just with the client. It does not parse/commit changes to gitignore files like it should...

Well, the gitignore works for everything except very specific *.dll and *.exe files in very specific sub-directories.

5:34 PM

I probably don't appreciate the difference because the only reason I use git on windows is to pull compile and push back stuff I've done on linux

So I never really use the windows prompt for much

@CᴏɴᴏʀO'Bʀɪᴇɴ your sandbox post reminds me that I wanted to make a meta post about whether golf courses are a bad idea :/

2

oh.

.___.

do you think it's okay?

I personally would like to see them ruled off topic unless there is significant interaction between the individual parts ("you can't use a language twice" is not that... "you can't use any character in two or more of the programs" is)

Oh, I see.

the main problem is that it circumvents the duplicate system

5:43 PM

I see. Should I delete it, then?

there are other problems though whose main symptom is usually "but what if someone copies only one of the 9 solutions from someone else?"

@CᴏɴᴏʀO'Bʀɪᴇɴ don't yet.

okay

and then there's also the question why someone wouldn't post them as separate challenges, to which the answer can only really be "because they're not interesting enough on their own", but then why are they more interesting if you throw 9 of them together?

Why post separate challenges when we can just have a list challenge?

2

this, basically

5:45 PM

Are any of the subchallenges redeemable? :/

@CᴏɴᴏʀO'Bʀɪᴇɴ 2 looks great

Yeah, but isn't it basically "Output the nth triangle number, reflected"?

the rest seem like they're either dupes or "I would never ask this as a separate challenge"

My advice: post on meta asking for a list of ways to improve your list challenge.

@CᴏɴᴏʀO'Bʀɪᴇɴ oh, number of pins

make it the actual pin indices instead

5:47 PM

Hm...

or come up with simulation rules that allow other results than perfect triangles

Like, spin?

Put locations between pins also.

So, 4.5

Oh... hm!

ah yes that would help

5:49 PM

(besides, hitting the center pin dead-on is a terrible way to try for a strike ;)

can someone find a multi-part challenge where there is no interaction at all between the separate parts (just sum your scores, no restrictions between subchallenges), except for Pyth[on] Practice challenges?

most of them seem to at least forbid or penalise reuse of languages.

ah, this one required all of them to be in the same language, that's better: codegolf.stackexchange.com/q/63014/8478

I'm still baffled that Mathematica has a builtin for goatiness. I shouldn't be, but I am.

That is a weird thing to have a builtin for.

Given an image of a game console made by Microsoft, Nintendo, or Sony, classify it as "Xbox", "Nintendo", or "Playstation"

mmmm not a bad idea

Anonymous

So you'd be looking at: [Xbox, Xbox 360, Xbox One, Kinect], [NES, SNES, N64, Wii, Wii U, GB, GBA, GBA SP, GBA DS, all the other DS variants], [PS1, PS2, PS3, PS4, PSP]

As suggested by your comic ... Mom (a variant of Foo), 10 bytes "Nintendo" ... outputs "Nintendo" for every image.

Anonymous

Maybe instead it should identify the game console and not just the generic brand

6:23 PM

@Mego Vita? What about variants, like the PSOne? Or color variations, like the 360 Elite? This is a pretty large scope.

Anonymous

@TimmyD Yeah, I'd need to narrow it down, definitely. Maybe just Nintendo vs Nontendo

That sounds interesting

Anonymous

Which would also balance the number of consoles on each side

@Mego Is classifying a new set of images still adding anything to this genre?

Also, just because I'm that guy ... technabob.com/blog/2007/09/24/xbox-gets-crammed-inside-an-nes

6:26 PM

@MartinBüttner Competitive answers would likely be looking for distinguishing text/icons/ports, which would be significantly different than the usual image classification answers that classify based on general shape

Since they're all rectangular prisms (for the most part), simple shape analysis won't get you far

Hm, possibly.

Huh ... I swear I've seen a "frame ASCII art" challenge before, but I can't seem to find it.

For example, if you could rule out the Wii U, from an image of the output ports, you could very easily classify it as Nontendo by the presence of an HDMI port
