~~Calvin~~ Helka and Knob don't use the Sandbox at all, so take that as you will :P

Anonymous

But they have a lot of experience with challenge writing

@Mego I tend not to either

@Lynn That's one of the reasons I don't like golfing languages, especially jelly because it's so darn short

@Lynn Very true. And I think that's something that has been discussed a lot on the site but no viable solution has ever been thought up besides "think of it as a competition within each language."

10:07 PM

It's like playing actual golf with a sniper.

omg why does rustc -v not work but rustc -V does? why would anyone try to use a capital first?

@CᴏɴᴏʀO'Bʀɪᴇɴ Says the author of multiple golfing languages...

@AlexA. One.

Y, Jolf

one my butt I see your github

10:08 PM

Y is not a golfing language.

badly ninja'd

Says the author of Jolf which by the way is really nice and does all sorts of things totally not endorsing it

Anonymous

I tend to upvote clever tricks in mainstream languages more than short answers in languages that do all the work for you

@AquaTart <3 thanks

I felt like this one could use some extra review

10:08 PM

@flawr yeah seems dodgy

@Dennis Y is a mental experiment of chaining programs. It only happens to be slightly golfy because it has single-char commands.

but I tend to be somewhat impatient

@AlexA. I've had at least one person tell me “code golf is interesting, but half of the answers on this site are keyboard-smashing in languages I've never heard about”... it's a difficult situation indeed v_v

@phase ?

@Lynn I can recommend Labyrinth. You could actually break new ground there. ;)

@Lynn On the one hand, yeah, it does appear that way to the uninitiated. On the other hand, maybe they should learn more languages :P

@Mego Thanks! Honestly I think waiting for Peter to be online for a bit is probably the best piece of advice ;-)

Oh, I see.

hmm

@AlexA. uuhh... If the challenge doesn't need much work I'm usually happy with 24h provided enough people have seen it.

@Mego BTW something I've wondered... is it pronounced "Mee go" or "Mego" (like Mega)?

10:12 PM

@MartinBüttner That's an odd reply to what I said >_>

I'm going to make a new language so I can learn Rust, anyone have any ideas?

@DigitalTrauma I pronounce it like "mega" in my head.

I do "mego" like "lego my ego"

Anonymous

@DigitalTrauma "Me go"

@AlexA. well you're entitled to your opinion, man

Was anyone else disappointed that today's xkcd didn't reference Zalgo at all?

10:15 PM

well that might get weird

@MartinBüttner Why Zalgo today?

@MartinBüttner yeah :|

Using diacritics correctly is not my fortÃ©.

@Dennis It's not needed in 3, but doesn't break anything with its presence. 2 needs it. Trying to write code that's compatible in both is a fun challenge.

Basically it tells Make that anything with the name specified in .PHONY isn't a file.

how does a challenge to output the image of an xkcd given the title sound to you people?

(accessing xkcd.com allowed)

annoyingly simple

annoying because I'd have to close Melee and open up Notepad++

you would have to search all the xkcds though

11:25 PM

get site, see where it redirects to, parse url to get the latest number, search in reverse

@MitchSchwartz Nevermind what I said. I mistakenly thought that 14 would work but all I got is another 64 haha

or start at one, which would save a billion bytes

actually, I forgot most golfing languages can't GET sites, so go for it

does this sound cool?

@CᴏɴᴏʀO'Bʀɪᴇɴ I might be missing something, but can't you just say that the opposite side are equal cuz its a rect?
