TIL (Today I Learned)

"Study hard what interests you the most in the most undisciplined, irreverent, and original manner possible." --Richard Feynman

This is a collection of short articles about things I've learned. They are too short for my blog.

I stole this idea from jbranchaud/til, who shamelessly stole that idea from thoughtbot/til.

The spirit of this project grew into Hashrocket's Today I Learned.
