A comic I did for a blog post ages ago (the site is dead now, sadly) which taught people some basics of RegEx using Pokemon as examples.
Don't worry if you don't get it - it's quite industry specific. Basically, Regex is a set of rules (in programming languages and other things) that allows you to determine certain outputs.
In this comic the idea is to use RegEx to search an entire computer for specific Pokémon using one line of code instead of hunting through boxes and boxes!
The guy in the comic is my friend Jules
