Overview of Python dependency management tools
I briefly describe each tool (pip, venv, pip-tools, pyenv, conda, pipenv, poetry and Docker), why it’s created and the problems it’s tackling. You can find a table summarizing all the information and the usual setups people use.

A Nix terminology primer by a newcomer
Maybe I just haven't been paying attention before, but in the last year or so, there seems to have been an increase in discussion around the Nix package manager. This is also what got me to finally try it, and I'm very happy with the results, even if the road is a little bumpy.

26 April 2018 by Phillip Johnston • Last updated 10 June 2021You may call them guidelines, heuristics, or rules of thumb. No matter, the purpose is the same: to provide a reasonable approximation of the truth. These rules of thumb can help guide your understanding of the systems you work on, focus you toward the ……

A simple way to get more value from tracing
A lot of people seem to think that distributed tracing isn't useful, or at least not without extreme effort that isn't worth it for companies smaller than FB. For example, here are a couple of public conversations that sound like a number of private conversations I've had. Sure, there's value somewhere, but it costs…

Xfce switches to GitLab
Starting today, May 1, we’re switching from our cgit/gitolite setup to GitLab. Our old server, git.xfce.org, is now a ready-only in-sync mirror (so you can still pull code). Our new server is gitlab.xfce.org.

Finding secrets by decompiling Python bytecode in public repositories
Cache rules everything around me. `pyc` files can contain secrets and should not be checked in to source control. Use the standard Python [.gitignore](https://github.com/github/gitignore/blob/master/Python.gitignore).

The use of `class` for things that should be simple free functions
For those who only read above the fold: I don’t say that all object-orientation is bad! OOP, especially classical polymorphic OOP, has a well-deserved place in real code. I’m going to talk about a very specific antipattern that I see with some frequency: the use of class for things that should be simple free functions.

Regexes vs. Combinatorial Parsing (2019)
Recently, I’ve been working on a music app that needs to get a musical sequence (like a melody) from the server to the client. To do this, we use a format called ABC. (You can read about how ABC music notation works here .) We chose ABC because it’s more readable than MIDI, it’s pretty concise, and it’s a standard, so…
