A divisor of a number n is any number that evenly divides n, including 1 and n itself. The number of divisors d(n) is how many divisors a number has. Here's d(n) for the first couple n:
n divisors d(n)
1 1 1
2 1, 2 2
3 1, 3 2
4 1, 2, 4 3
5 1, 5 ...
@LeakyNun Hey Kenny, do you remember that "is x a power of y" question that I answered with a regex? Turns out that Ruby's base conversion on works with bases 2 through 36. For more general cases, I'll have to think of another algorithm
Would anybody mind reviewing and giving me some suggestions on a video I'm making? It's an ad for my friend's resource pack and I'm not sure what else to do with it (besides add music, but we're getting there).
Hi! I have three questions: 1. There is no invisible in the chat, so everybody who appears offline really is, right? 2. How can you contact someone who is not in the chat right now? 3. If you post a comment to your own answer to some challenge, will the person who asked the challenge receive a notification about your comment?
The answer to 2) kinda depends on how long they haven't been in chat for/whether they've been in chat before. If it's been too long, then pinging won't help.
The 24 Game is a card game. On each cards are four interger numbers. For a player, the goal is to use Addition, Subtraction, Multiplication and Division to end up with 24.
The goal of this code golf/puzzle is to write a program that, for four intergers, will state the one or multiple solutions p...

Smallest Number to add up to its origin
Perhaps you know the term "digital root" which is the sum from every single number making up a number (Originnumber 11 -> Digital root 2 = 1 + 1).
The challenge is to write a program to calculate a kind of reversed digital root (since there is no possible...
@PhiNotPi Found offer for phinotpi.com on 1&1. Got 3 unrelated domain offers with that:

ICANN (or IANA, I forget which) governs TLD's. Each TLD can have a sponsor company, who govern registrations of domains under it. A domain name registrar (DNR) simply asks the sponsor if the domain is registered; if it's not and you want to register it with that DNR, they ask the sponsor to point the domain to the DNR's nameservers, which they use to give you control of what happens with it after that.
@flawr Uhm, they already do. TLDs are not regulated by some company, but by the DNS you are using. If you want a new TLD, you just need enough DNS servers to agree with you ;-)
@quartata Exactly. I don't remember what TLD it was, but there was a fairly popular custom TLD a long time ago and ICANN just annexed it. So if "your" TLD is popular enough, they'll eventually just take it from you.
@Sp3000 Sorry late reply. The four functions usually allowed are +, -, *, /. Barring a function f(x) = c any exponential, factorial, logarithmic, trigonometric, mathematical in general that doesn't just return a constant is valid. But your score is by how many of the possible arrangements of cards your system can solve, then by how many of those extra functions you extended the game by
@CᴏɴᴏʀO'Bʀɪᴇɴ I think the challenge would either end up being find the moves from the start to the given configuration, or given a list of moves return a golfed solution to get to the resulting configuration. Both are the same as solving the puzzle, but the 2nd is presented in a more creative way.
@CᴏɴᴏʀO'Bʀɪᴇɴ Also, I think I just proved that any configuration of lights on/off can be reached.
@mbomb007 Some people have a sock puppet account (another account that they don't declare is under their control). I was joking because Sok joined the room with a similar avatar to you, so your avatars were adjacent on the avatar bar at the top right of the screen.
@CᴏɴᴏʀO'Bʀɪᴇɴ Your auto-moves don't get added to the move list.
@CᴏɴᴏʀO'Bʀɪᴇɴ Here's the first glider I found, though it's not the most famous position of the glider: [[0,2],[2,0],[0,0],[1,1],[0,1],[0,2],[2,1],[2,2],[2,1],[1,2],[2,2]]
@QPaysTaxes What if the challenge was to find the shortest solution.
