A Puzzle about a Calculator (aperiodical.com)
It’s now been a year since I took over the puzzle column at New Scientist and turned it into the BrainTwisters column. By way of celebration, I thought I’d write up an interesting bit of maths behind one of the puzzles, which I made a note of at the time and have been meaning to share.

Show HN: I made a calendar where every month is also a crossword (aaronson.org)
Ever heard of the Tetris effect? It’s where you play so much Tetris that the game starts to seep into your thoughts, your dreams, your half-waking hallucinations, and pretty much every part of your reality that has nothing to do with Tetris. Well, I do a lot of crosswords—by “do” I mean both “solve” and “make”—and it turns out the “crossword effect” is also a very real thing.

A boy girl paradox – or maybe not? (shankwiler.com)
The most liked comment answers 1/2, but the user got worn down by others until he recanted and agreed that the answer is 1/3. Many other comments give lengthy explanations as to why the answer is 1/3.

Can a Rubik's Cube be brute-forced? (stylewarning.com)
When I was about 13, while still a middle-schooler, I became fascinated with the Rubik’s Cube1. I never got terribly good at solving it, maybe eventually getting into the 30 to 40 seconds range. While I didn’t have a penchant for memorizing move sequences, I was drawn into how we find these move sequences.

Solving Sudoku in Python Packaging (github.com/konstin)
Solving the versions of python package from your requirements is NP-complete, in the worst case it runs exponentially slow. Sudokus are also NP-complete, which means we can solve sudokus with python packaging.
