Do-nothing Polyglot
Challenge
This challenge requires you to write a polyglot which contains as many types of comments possible.
The comment must say This is a polyglot comment.
The program must do nothing at all.
Besides comments, your code may contain no-ops from the language(s) you are usi...
@MartinBüttner So you're converting to numbers from 1 to 26, adding the numbers in the same position in the strings, mod 26, and undoing the conversion to numbers
while we're trying to get back on topic, I've created something like a Game of Life on an icosahedron... despite a really naive guess at the rules it seems to be pleasantly chaotic (provided I don't have a bug):
Does my lipogramming challenge during December count as something that I can put on PPCG memes if I find the messages where I started the challenge, accidentally typed e once or twice, and finally finishing the challenge?
I've got my A181018 solver outputting the grids, so I can check their plausibility, and it looks good. Estimate 11 hours to calculate A(15), and 3 days for A(16).
okay, that icosahedral game of life instance seems to have a period of 100, although it appears that up to rotation/reflection or something the period is only 10
When I was younger, I use to play a word game called Word chain. It was very simple. The first player chooses a word; the next player says another word that starts with the same letter the previous word ended with. This goes on forever until somebody gives up! Trick is, you cannot use the same wo...
Your task is to create an algorithm/programme which takes a black and white outline image (creative commons example images below) and fill it in with colour.
EDIT: Due to anti-aliasing on lines causing non-black/white pixels and some images that may contain grey instead of black/white, as a bonu...
Make a Punnett Square! - Part 1
In genetics, a Punnett Square is used to find the probability of a genotype, the genetic basis of an organism, of an offspring based on the parent genotypes. I will explain how to do one by doing an example. Let's say the parents both have a genotype of Aa. Since ...
@FlagAsSpam fair enough. still ridiculous. when I was studying in Potsdam (next to Berlin), I got a semester ticket (6 months) for Berlin and Brandenburg (the federal state surrounding Berlin) for all local transport systems and regional trains for something like 150 euros.
