Write a function calc_rel_frac(a,axis=0) that takes a 2-dimensional numpy array and returns the proportion of ones in each column or row divided by the column or row that has the smallest proportion of ones. (As in the previous question, the axis argument controls whether the function should be e...
There are some great programmers who can write code without taking any breaks or looking up documentation. I am not one of those people, but I've come up with a clever solution. Instead of spending time learning languages, I'll get you guys to write a program that makes it look like I'm program...
I think LLVM has no way to simply assign the value of register A to register B, so I'm creating a one-element struct containing the value of A, and then extracting it into register B.
It's 42!
This challenge is to codegolf a program that proves that the next number in a pattern is 42 based on the website Actually it's 42.
In your program, the user inputs a pattern of numbers and it has to output the equation that proves that the next number is 42.
For example the user input...

@MistahFiggins Fun fact: I'd changed my PPCG username to Totally Not Mistah Figgins for about 20 minutes after you sent that but the chat username refused to update so I changed it back
So I have a matrix challenge (quandles), and someone is inquiring about being allowed to use 1-indexing instead of 0-indexing. Thoughts on whether I should allow that? On one hand, it's really not that big a deal, but on the other, it means the submission could only handle quandles up to order 9 instead of order 10.
I'm not familiar with matrix quandles, but is there any situation in which only having to handle up to order 9 would give someone an unfair advantage? (As in, does not having to handle order 10 quandles simplify the procedure at all?)
@PhiNotPi In languages that use 1-based indexing (Octave, Julia, Jelly, etc.), dealing with 0-based indices is a bit of a nuisance, so unless there's a very good reason not to, I'd allow both.
I wonder what I should do for "Episode II." Some ideas are: creating a conjugation quandle from a group, determining if a quandle is a conjugation quandle, evaluating a quandle expression, or knot theory stuff.
I'm only going to include questions, answers, users, comments, voting, comment voting. No spam protection, no flags (yet), you can't change your vote ever, and other implementation-simplifying details
This is weird: 90% of my StackExchange rep is from PPCG, but my top-voted question and now my top-voted answer are on other sites. Dunno if that says more about PPCG voting patterns or about my participation.
CMC: given a string in a certain written language (e.g. spanish) output the language that it is in. You may (and are encouraged) to use preexisting online resources (e.g. google translate)
CMC: name a commonplace, non-coined, non scientific, non proper noun word that has the same meaning and spelling in as many languages as possible. e.g. "omelette" scores 3 for french, english, and german
Someone in Code Review chat made a userscript to allow the formatting [badge:a-real-badge-name] in chat to actually display correctly along with the badge's rank etc.
