Setting up a Docker dev environment for Elixir+Phoenix
Benefits One-line setup and bootup: docker-compose up.

First example that comes to mind: software development done too quickly which creates technical debt as it goes. In the short term, a project like that can seem very successful, exceeding expectations for delivery time and customer satisfaction. And then…More
Python vs. Haskell round 2: Making Me a Better Programmer

I started with the Python implementation, and wrote this test: Very simple: I had already downloaded the web page and so this function had to do just two things: (1) read in the file, and then (2) parse…More
