I've been developing some programs involving me fetching a vector from a url using Alpha-2 country codes (such as GET /jp.svg for Japan). Except, oh no! All the country data on my computer uses Alpha-3! That just won't do...The task is simple: Take an Alpha-3 country code (e.g. UKR) and return i...

As of recently, we've lost 3 of our 4 moderators. This means we only have 1 moderator left. Also, several people are expressing their concerns that things are dying around here. With the recent mess over on SE, the growing inactivity of past regulars, and a presumable lack of people wanting to ...

TL;DR: "The sca.js pixel as mentioned collects data required for ad verification. There is no individual user tracking happening as the browser signals they collect via their js does not collect any PII." is wrong, SO isn't starting audio but ads use it for fingerprinting, IAS ToS + GDPR invalida...

I often have my browser's devtools open since I'm often debugging a snippet. I noticed this message often recently: Why is Stack Overflow trying to start audio? Update. I see it's from an ad(?). https://static.adsafeprotected.com/sca.17.4.95.js Update 2 It happens when this ad appears, f...

Desmos, 124 bytes b(n)=mod(floor(n/2^{[floor(log_2(n+0^n))...0]}),2) d(l)=total(2^{[l.length-1...0]}l) c(l)=l[length(l)...1] f(n)=d(c(b(n)))^2 Try it on Desmos!

Desmos, 30 bytes f(n)=random(-mod(n,2)).total+n A lot of stuff that I tried just gives undefined instead of erroring out, but I finally found something that worked. There must be something else that's shorter than random() + total, but I don't see it at the moment... Try It On Desmos! Try It On ...

Derivative of a product In calculus, the derivative of a mathematical function defines the rate at which it changes. The derivative of a function f(x) can be marked as f'(x), and these can sometimes be abbreviated to f and f'. The derivative of the product of two functions fg is f'g + g'f. The de...

Add a language to a polyglot was fun while it lasted. However, it's kinda stagnated due to the difficulty of running all the languages. I propose that we repost this challenge, maybe with stricter rules on what types of languages can be used but otherwise exactly the same. The current consensus o...

Shortest restricted superstring code-golf string optimization subsequence Let \$ a \preceq b \$ denote "\$ a \$ is a substring of \$ b \$". This is a non-strict substring relationship, so \$ a \preceq a \$ for all \$ a \$. Given two sets of strings, \$ D \$ and \$ R \$, find the shortest string \...

Is Wally there? code-golfarraydecision-problem Inpired by recent Stand-up Maths' video. Task Given a list x of positive digits and an array A of positive digits determine, whether any array made of wrapping x contains A. Rules Any reasonable input format is acceptable (list, string, array, etc....
