I write. Here are some stuff I've written:

  1. 0a explains: calculus (188 points in HN, 500+ on reddit)
  2. 0a explains: axiomatic set theory (190+ upvotes on reddit)
  3. The Boolean Satisfiability Problem in 5 mins or more
  4. Jekyll in 3 minutes

I'm putting them here for SEO basically. Not sure if it actually helps though. Just like any typical 19 years old, I love the fact that when you google "calculus explained" my article appears at the first page です.
