there are lots of people who have a knack for things that don't fall into the traditional Stanford-Binet definition of "gifted". Nor does it account for a person who matures in their teens or 20s or beyond. I am also somewha

I think Clojure or ClojureScript is a very important as a member of the Lisp family and yet also compiles to Java or JavaScript. This is complementary to languages like Elm or Haskell which emphasize type purity. I have gone the second ro

i can't speak for everybody or for all book consumption. in New York City book consumption is unevenly distributed. there are places like Strand Bookstore where thousands of books in carts are left out in the street. I found a copy o

there is ClojureScript Koans if you want to learn tiny bits of FP. I held a meetup event once everyone really liked it. Since we were all learning JavaScript already http://clojurescriptkoans.com/

here is a more technical discussion by Paul Bourgade @ NYU. I still re-read it from time to time for orientation. Quantum chaos, random matrix theory, and the Riemann ζ function http://www.cims.nyu.edu/~bourgade/paper

I program with Elm which aspires to compete (or coexist) with React. Basically I am going to have to learn React as well in order to do interOp. So, extremely helpful.

Microsoft is kind of like McDonald's. If I want a decently cooked burger I should cook it myself. If I am totally unfamiliar with an area, I go to McDonalds. I expect a certain minimum from Microsoft and the book exceeds that. Also U

there's a nice trick in Thurston's book on 3-manifolds where you glue a strip of paper at the ends into a Möbius band and cut along the middle to get a trefoil knot out of paper. i did it with 3 and 5 twists and cut along the midd

the challenge for this style of app is to balance mathematical content with good UX/UI. It is tempting to sacrifice one for the other. also from yesterday: https://news.ycombinator.com/item?id=13256222

i think this is really cool. Can anyone remind me (on formal grounds) why a programmer might be interested in a compiler LISP --> GO-lang I am a huge fan / user of Python (which is an interface to C) but that also did take
