Q: matrix determinant

Calculate the determinant of a n x n matrix. Rules read matrix from standard input write to standard output do not use ready solutions from library or language input: columns separated by any space char input: lines separated by cr and/or lf Winner The shortest code :)

Q: Should we have a new, improved matrix determinant challenge?

There is currently a challenge to compute the determinant of a matrix. However, it was written 5 years ago, before our current quality standards were established. It falls short of those standards in several ways: Inflexible I/O (must be STDIN and STDOUT) Cumbersome I/O format (whitespace-separ...

There's a Mathematica extension to generate optimized C++. Idea: run it on a single built-in then use the interop most languages have with C++ to call it and never implement ObscureMathFunction manually again.

Shell (computing)

In computing, a shell is a user interface for access to an operating system's services. In general, operating system shells use either a command-line interface (CLI) or graphical user interface (GUI), depending on a computer's role and particular operation. It is named a shell because it is the outermost layer around the operating system kernel. The design of a shell is guided by cognitive ergonomics and the goal is to achieve the best workflow possible for the intended tasks; the design can be constricted by the available computing power (for example, of the CPU) or the available amount of graphics...

Sorry if wrong room, but was there any suggestion on meta to add sorting by byte count in answers? I think that would be better than the snippet. Just click a tab and the answers are sorted the way the leaderboard snippet does

caird coinheringaahing

@Soaku We have had that feature request, but given that not all answers use the same answer format, I think it was rejected. It might come with the site design if we're lucky though.

Soaku

@cairdcoinheringaahing, but why not include a (?) sign next to it, explaining the format? I think that could help...

@Soaku an answer template hes been suggested too IIRC

@Soaku here is the suggestion in question

Soaku

@dzaima, So what's wrong with it, heh? Let's just hope they'll implement that with site design, as @cairdcoinheringaahing said.

caird coinheringaahing

I think the biggest problem is that it would be quite a bit of work, just for this one community, so SE wouldn't really do it, given that they basically ignore us as much as they can

@Soaku The problem is that the design should've been made like a year ago :p

Soaku

@cairdcoinheringaahing, but... well... It's already implemented. But just as a stack snippet. So... I don't think that it would be really hard

caird coinheringaahing

@Soaku Well, the stack snippet doesn't sort the answers on the actual page, just in a separate window.

dzaima

@Soaku There's also the PPCG design collaboratively made by users here which adds byte count sorting to every question (plus many other things)

Soaku

@cairdcoinheringaahing, ikr, but still, they could make it, by modifying the code
