From Rodrigo, @mathsppblog@fosstodon.org, A crossword where all hints are regular expressions!
Regex isn't hard enough, so I present you with a crossword where all hints are regular expressions!

I confess at first it looked like the hints don't contain enough information to solve the puzzle but after some slow but steady progress I can confirm that they do 🤣

The original puzzle is from https://puzzles.mit.edu/2013/coinheist.com/rubik/a_regular_crossword/

I shared this on my blog: https://mathspp.com/blog/problems/regex-crossword

I printed it out, and it took me a couple of enjoyable hours to solve. I did have to check my understanding of the finer points of regular expressions at https://regex101.com by typing in some of the clue expressions and then trying different values to see if they matched.

You get 47 geek gold stars for this one!

(Seems like this would be a good programming test for a job interview)

Do primes always make for nice triangles?

silveradept: A kodama with a trombone. The trombone is playing music, even though it is held in a rest position (Default)

That is quite the test, and that it is only part of that year's Mystery Hunt shows just how much the MIT folk enjoy making and solving puzzles.
