Programming Achievements: How to Level Up as a Developer

This gist is part of a blog post. Check it out at:

http://jasonrudolph.com/blog/2011/08/09/programming-achievements-how-to-level-up-as-a-developer

Learn a variety of programming paradigms:

• Write a program in assembly language

    //The file goes through heuristics that turn object properties into
    //a hash table
    //run with
    //d8 --enable-natives-syntax prop_heuristics.js

    //Note that even if object has fast properties, there are still 2 kinds of
    //fast properties (in and out of object) and only one of them is even faster.

Tail-Recursion helper in Python.

Inspired by the trampoline function at 
http://jasonmbaker.com/tail-recursion-in-python-using-pysistence

Tail-recursive functions return calls to tail-recursive functions
(themselves, most of the time). For example, this is tail-recursive:
