(How to Write a (Lisp) Interpreter (in Python))
This page has two purposes: to describe how to implement computer language interpreters in general, and in particular to build an interpreter for most of the Scheme dialect of Lisp using Python 3 as the implementation language. I call my language and interpreter Lispy (lis.py). Years ago, I showed how to write a semi-practical Scheme interpreter Java and in in Common Lisp). This time around the go

Why Python is Slow: Looking Under the Hood | Pythonic Perambulations
We've all heard it before: Python is slow. When I teach courses on Python for scientific computing, I make this point very early in the course, and tell the students why: it boils down to Python being a dynamically typed, interpreted language, where values are stored not in dense buffers but in scattered objects. And then I talk about how to get around this by using NumPy, SciPy, and related tools

Mailbox has grown unbelievably quickly. During that growth, one performance issue that impacted us was Mongo DBâ€™s database-level write lock. The amount of time Mailboxâ€™s backends were waiting for the write lock was resulting in user-perceived latency. While Mongo DB allows you to add shards to a Mongo DB cluster easily, we wanted to spare ourselves potential long-term pain by moving one of the most f
