all the talk about this has been on the discord but I just feel like patting myself on the back a bit more for actually being on the global leaderboard for day 5 of advent of code
while Doorknob is just casually global rank 4 across all stars lol

Background
A Latin square is a square grid of side length \$ n \$ filled with \$ n \$ different symbols, where each row and column contains each symbol exactly once.
Let's define a row (resp. a column) as a maximall...

Round up my number code-golf sequence
In this task you should create a function or sequence that deals with the following sequence that is (astonishingly) not on oeis.
Here is the sequence in its full glory:
3, 3, 3, 6, 6, 6, 9, 9, 9, 12, 12, 12, 15, 15, 15, etc.
What's that frequency?
This is my first code-golf challenge, so apologies if it is a little unclear/already has been done. I gave the past challenges a good look over, but I may have missed something.
Create a function or a full program which accepts a frequency value, and then outputs the clo...
You get a string which contains an integer between 1000 and 99999999 as input. The input string might contain leading zeroes but cannot be longer than 8 characters.
Your goal is to output all dates between 6th of December 1919 and 5th of December 2019 which fit the input in these formats:
day ...
While I'm unclear how useful this would be, you can wrap the code in <pre><code>...</code></pre> blocks, such as:
>! <pre><code>
>! function hidden() { }
>! </code></pre>
Which produces:
I'm pretty sure you'd lose any syntax highlighting.

@cairdcoinheringaahing Hold on, anyone can put anything on Wikipedia. That doesn't make it true. That notation isn't mentioned on MathWorld. [citation needed]
Name the hydrocarbon
A hydrocarbon is a chemical compound which consists of only hydrogen and carbon atoms. For this challenge, we will only consider the three simplest kinds of hydrocarbons: alkanes, alkenes, and alkynes with no branches.
An alkane with \$n\$ carbon atoms contains \$2n+2\$ hyd...
Game of putting lines through dots.
This is a game that I remember having learnt from my grandparents in my childhood, but don't know it's name nor origin. (if you know I would appreciate that).
Description
The game is played by a single player on a 2-dimensional infinite grid.
The grid at the...
