I transcribed some videos.

In building your Python application and its dependencies for production, you want to make sure that your builds are predictable and deterministic. Therefore, always pin your dependencies.

Some thoughts on how I like to write libraries as "open source" projects.

Today, I'm open sourcing a project that I've been working for the last few months. It is a Python library to put work in the background, that you'd typically use in a web context. It is designed to be simple to set up and use, and be of help in almost any modern Python web stack.

Finally, I've made the move to a static blog engine! I'm using Nanoc now. Nanoc is a very flexible and customizable static site generator, written by Denis Defreyne. As with all static site generators, nanoc lets you write your source files in a simple markup language. However, nanoc is much more flexible and customizable than most of the others out there. Let me show you a sneak peek of its internals.

After the overwhelming attention and feedback on the Git branching model post, a general consensus was that this workflow would benefit from some form of proper scriptability. This post proposes the initial version of a tool I called git-flow.
