Julius

I love math, rally racing video games, statistics, and number theory (in that order). My primary professional experience has been maintaining PyMongo, PyMongoArrow, Motor, and PyMongoExplain. Before that I did a research project utilizing advanced NLP techniques to categorize patents.

Recent projects:

I also love messing around with the Python interpreter and internals:

  • I made a concurrency fuzzer that injects byte-code to opportunistically release the Global Interpreter Lock called Confuzzion
  • I made a transpiler from Python to MongoDB Aggregations called PyMongoAgg
  • I made a tool that transpiles Python code into expression-only syntax (lambda functions and list comprehensions only), in addition to reflowing that code into ASCII art called Exprify

    I recently discovered a relatively obscure algorithm for calculating the digits of pi: https://en.wikipedia.org/wiki/Gauss–Legendre_algorithm.

    Well, at least obscure compared to Chudnovsky's. Wikipedia notes that it is "memory-intensive" but is it really?
