@xnor I think so. But since you've whitelisted things anyway, you might as well add a sentence that all other functions related to modular arithmetic and equation solving are disallow unless explicitly whitelisted.

that would ban some innocuous things like subtraction mod n
actually, i think that's fine; i just whitelist subtraction
@MartinBüttner OK, thanks, I posted it with your suggestion.
do you have any ideas for what i'd need to restrict for rank-one matrices to be similarly mathematica-proof?

xnorIs this matrix rank-one? code-golf Your goal is to check whether a given integer matrix is rank-one, using as few bytes as possible. A matrix is rank-one if every row is a multiple of the same vector. Example: 2 4 20 10 -3 -6 -30 -15 0 0 0 0 The definition also holds true ...

@xnor Well Mathematica has a built-in MatrixRank but I'm not too familiar with linear algebra to tell you what the the other ways are you could go about it
@PhiNotPi can languages be reused?

Finally! I wasn't able to log in to chat for 16 hours.
Which one of you kicked me out? :P

And even more interestingly, it's not even the dumbest name for a place here.
TL;DR "The name, in Finnish, means "the island shat by Saara""

@aditsu mr works with negative doubles but not with negative integers? :/

have something smaller ? :P
also, that has to be a dupe, no ?

@Optimizer lol no
I don't think it's a dupe though
I guess nobody dared so far to post that trivial a challenge ;)

Okay, I've decided that, if I ever have any chance at learning a language without putting in too much effort, Lojban is my best bet.

I would state that 'learning' Timlan is trivial, it's just that it's entirely pointless ;)

It took me a while to find a decent Lojban dictionary.

Q: Non-printable characters in answer?

orlpThis mostly applies to kolmogorov-complexity questions. Is it allowed to use non-printable characters in answers? This effectively makes the answer a string of bytes. If yes, how is the answer supposed to be supplied, considering that non-printable characters won't be correctly displayed?

@Phi what about reusing languages for Evolution of OEIS?
oh he's already gone again...
or maybe not :)

I haven't really decided on that.

well, without any further restriction there isn't gonna be an end to the challenge
yay, I got Revival and Necromancer on Arqade :)
these two took me ages on PPCG :D

KOTH idea: necromancy

A: Sandbox for Proposed Challenges

ymarThe Kaplansky Challenge I've been reading this forum for a bit and I thought it might be a good idea to do a short sequence of challenges themed on famous mathematicians. It's my first post here so please point out any shortcomings. It is Irving Kaplansky's birthday today. Among other things he...

I just figured out why this code removes all the contents of my file.
