@Liam I see you timed my Python answer in a 100-fold loop. Could my C answer get the same love, maybe even with 1000 iterations? I made a two non-trivial improve since the last official score. It should be a lot faster now.
 
yessir
I should be able to do it within the hour
 
No hurry. Thanks!

A: Sandbox for Proposed Challenges

ZgarbRobot on a ladder code-golf counting Background I have a ladder leaning on a wall, and a remote-controlled robot that can climb it. I can send three different commands to the robot: UP: the robot takes one step upwards. If it was on the highest step, it trips over, falls down and explodes....

Q: Can't find clit

j0hI have some lit files I want to convert from mircrosoft reader files to something my other devices can read. My friend says I should have clit, in $ which clit /usr/bin/clit but I cannot find it. I tried locate clit but the results are unrelated. So then I tried sudo apt-get install clit but ...

ohh, it was already posted here, I just haven't scrolled up enough
 
I am not so much into that kind of humor, but just minutes after a workday, to find clit you need calibre ... It's hard to refrain from laughing. — phresnel 3 hours ago
 
ಠ_ಠ this entire conversation
 
I was like, "no, I won't click on it, I'm not that juvenile", turns out I am
 
8:10 PM
Yeah, saw that this morning. Chuckles were had. =P
 
which clit
The fact that this is a valid command on his computer is preposterous.
 
locate clit

^ Same with that one.

That might be a better question for Biology.SE
 
( ͡° ͜ʖ ͡°)
 
8:16 PM
@mınxomaτ I think it's only on half
 
@MartinBüttner Forks would be useful, too. I also would like a way to negate the Transliterate mode. Say I wanted to translate everything but two classes. "T`[^a-f][^0-9]`"
 
randomra mentioned this, but I feel like class negation doesn't make as much sense in T-mode... which character remain? all Unicode?
maybe range-subtraction would be an option
 
Yeah... range/set subtraction would also work.
But replace mode will do this fine for now.
 
@Dennis retimed it.
0.06 seconds on my computer
hilarious
 
\o/
The improvement was even more significant on your machine.
 
8:22 PM
yeah pretty huge
I didn't really expect it to make such a big difference.
Something to keep in mind for future challenges
 
Peak memory consumption is 6.7 MiB now.
 
is there a particular resource you used to implement it?
I kind of want to see if a rust entry using the same algorithm will come close (If I can figure out how to rust long enough to make it)
 
@MartinBüttner what would be a great feature is to match only length in backreference (e.g. (abc)\L1 would match abcdef), do you still use the .Net regex execution r your own?
 
@Liam I used the first Google hit, which was the Wikipedia page of the prime-counting function.
 
I'm using plain .NET regex and I'm not going to write a new regex engine any time soon ;)
 
8:26 PM
In mathematics, the prime-counting function is the function counting the number of prime numbers less than or equal to some real number x. It is denoted by (unrelated to the number π). == History == Of great interest in number theory is the growth rate of the prime-counting function. It was conjectured in the end of the 18th century by Gauss and by Legendre to be approximately in the sense that This statement is the prime number theorem. An equivalent statement is where li is the logarithmic integral function. The prime number theorem was first proved in 1896 by Jacques Hadamard and by Charles...
 
before I do that I want to do some pre-processing of the regex, which should probably allow me to implement this, but even that will take a while
 
@Quill I just found out about this via Imgur on Facebook. :P
 
but yeah that would be useful
open an issue on github? :)
 
@MartinBüttner I remembered vaguely something, like you rewrote it, but that seems like a big hassle
 
I rewrote Regex.Replace
(but the reimplementation is based on Regex.Matches)
 
8:27 PM
I see
 
Haha of course that would be a good place to start
I'm adding it to my list of to-dos
 
@MartinBüttner will do soon

Argenis GarcíaIn Linux its a common mistake to type sl instead of ls, which shows a pretty funny animation of a train.

Huh. I like it, but I don't totally know why.
Also, I'm realizing how bad the lyrics are.
 
Haha, I pretty much always like their covers more than the originals=)
 
I'd never heard of them before.
Have any more recommendations of particularly good covers they've done?
 
I'm digging the horns. I love me a good horn section.
 
Hey, when using SOCKS through an ssh tunnel, do I look for the SOCKS server being located at localhost, or the remote?

any more sandbox comments for this one, before I post today?

@VoteToClose perhaps the subliminal message in your userid? ;-)

why do you think I have this avatar?
 
@DigitalTrauma Maybe a test case that has nested and/or concatenated braces with the {start..end..step} syntax?
 
@Zgarb ok, I'll add one

I'm supposed to be doing inventory for my own computer, and one of the questions is "Was it purchased in 2015?" If the memory was purchased in 2015, but the rest of the machine was purchased in 2013, do you think he cares?
 
Yes.
Why the inventory @Rainbolt?
 
@EasterlyIrk They do inventory every year as far as I know
And rather than go around actually doing inventory, they crowdsource it

We need a site blog.
Dennis can post golfing tips there.
 
We already have a blog for people to post their golfing tips. It's on main.
(You have to sort by active for it to look like a blog)
 
9:42 PM
@Rainbolt You... pointed someone to a tips post? End of days have come...
 
@NewMainPosts Wow, I came up with the sequence expansion idea before I saw this! :D
 
@EasterlyIrk I think @Doorknob considered setting one up
 
@El'endiaStarman Do you know the license on this image (if any)? I can't find it, but have an idea on how to use it in something.
 
@AquaTart Found your (possibly evil) twin by chance: codegolf.stackexchange.com/users/36926/kevin-workman
 
9:47 PM
@Bigtoes haha, yes
 
@Bigtoes Hop down to the "Frequently Asked Questions" section here. Looks like all you have to do is tell the creator that you're using that comic.
 
I have quite a couple evil twins on SE
 
@El'endiaStarman Geobits pinged the milky way image
 
@El'endiaStarman Err, not the comic. The Milky Way.
>_<
 
@Bigtoes They give a reference to the ESO website, which lead me to their copyright page
Looks like it's CC-BY
 
9:47 PM
How did I miss that.
 
Ok, thanks room for finding stuff out for me so I don't have to.
 
I am room, yes
 
Well, know you know even more stuff you didn't need to know! :P
 
@Roujo That's how you pronounce it, right?
 
isn't there a proper place for codegolf.stackexchange.com/q/74456/47019 ? it seems like a good question, but apparently it doesn't even belong on meta ( see here meta.codegolf.stackexchange.com/questions/1723/… and here meta.codegolf.stackexchange.com/questions/8619/…)
 
9:49 PM
@El'endiaStarman Like the fact that the source of the ESO Copyright page contains the letter 'e' 6155 times?
 
Definitely not main or meta.
I honestly think that it doesn't belong in any particular place.
Maybe in "Showcase your language"
 
@AquaTart but why not? the comments just don't say WHY
 
Because the community decided so
I know, it's a dictatorship ;)
 
well that sucks. but WHY did the community decide so? (I know, i'm being a toddler)
 
@Bigtoes IPA: [ʁuʒo], I believe ^^
 
9:52 PM
@epicTCK The comments link to the meta post that gives the arguments, don't they?
 
@epicTCK no, not really, to be honest
 
FWIW, I agree that it's an interesting question, and would be interested in seeing a well written answer. I don't think it fits our scope, though.
It's more of a trivia question than anything.
 
I just hit random on XKCD and got Hoverboard.

Sometimes I feel like the "random comic" button isn't actually uniform. It feels like it's a Gaussian distribution

Oh, for the hexagony quine? Cool!

Yeah. I like rewipes.

Q: Highly composite numbers

Don MuesliA highly composite number is a positive integer that has more divisors than any smaller positive integer has. This is OEIS sequence A002182. Its first 20 terms are 1, 2, 4, 6, 12, 24, 36, 48, 60, 120, 180, 240, 360, 720, 840, 1260, 1680, 2520, 5040, 7560 For example, 4 is in the sequence becau...

I love how the right "popular" column is just Leonardo NoOscaro memes.
 
@flawr Wow, the weight must've been too much. And I'll bet that from that day forward, those people picked the stairs. :P
 
@El'endiaStarman I cannot imagine that there was too much weight. All elevators etc. do have to have huge safety margins.

@MitchSchwartz Good question...
 
maybe people will only post answers with horrible complexity, though
this problem collided with SPOJ and hasn't been an issue (so far) codegolf.stackexchange.com/questions/55240/…
anarchy golf's "create new problem" page has an etiquette note, "NOTICE: Please check if your problem with deadline is not included in other short coding sites such as codegolf.com or Shortening codes at SPOJ. As they don't disclose code, your problem can be a spoiler for these sites." golf.shinh.org/mkprob.html
 
10:58 PM
is minifying a SASS/LESS file an NP-hard problem?
 
@MitchSchwartz No problem for PPCG - we always have spoilers visible. :P
 
Are we included on that list?
 
@El'endiaStarman The other way around, though...
 
is the python quine
SyntaxError:Invalid Syntax
Cheaty?
 
11:14 PM
Yes
We call those “error quines”
 
@Lynn true
 
they're also called kimian quines, sometimes
 
@Lynn I think that that challenge would have been more interesting as a code-golf
searching everywhere for those super short errors :P
then Java would really lose
