This is a list of guides I wrote on this blog. They are setup guides for some technologies, or ways to implement best programming practices.

  • Deploying Python Web Applications with nginx and uWSGI Emperor

    Topic: Python, web apps Platform: Ubuntu, Debian, Fedora, CentOS, AlmaLinux, Rocky Linux, Arch Linux

    You’ve just written a great Python web application. Now, you want to share it with the world. In order to do that, you need a server, and some software to do that for you.

    The following is a comprehensive guide on how to accomplish that, on multiple Linux-based operating systems, using nginx and uWSGI Emperor. It doesn’t force you to use any specific web framework — Flask, Django, Pyramid, Bottle will all work. Written for Ubuntu, Debian, Fedora, CentOS 7, Alma Linux, Rocky Linux and Arch Linux (should be helpful for other systems, too). Now with an Ansible Playbook.

    Revision 8 (2022-02-20): works with Fedora 35, AlmaLinux 8, RockyLinux 8

  • Python Virtual Environments in Five Minutes

    Topic: Python virtual environments Platform: any platform

    In Python, virtual environments are used to isolate projects from each other (if they require different versions of the same library, for example). They let you install and manage packages without administrative privileges, and without conflicting with the system package manager. They also allow to quickly create an environment somewhere else with the same dependencies.

    Virtual environments are a crucial tool for any Python developer. And at that, a very simple tool to work with.

  • Setting up a Python development environment

    Topic: Python Platform: Windows, macOS, Linux

    Setting up Python is usually simple, but there are some places where newcomers (and experienced users) need to be careful. What versions are there? What’s the difference between Python, CPython, Anaconda, PyPy? Those and many other questions may stump new developers, or people wanting to use Python.

  • Spawning subprocesses smartly and securely

    Topic: spawning subprocesses Platform: Unix/Linux (and partially Windows)

    As part of your code, you may be inclined to call a command to do something. But is it always a good idea? How to do it safely? What happens behind the scenes?

  • Python Apps the Right Way: entry points and scripts

    Topic: Python Platform: any platform

    There are multiple ways to write an app in Python. However, not all of them provide your users with the best experience.

    One of the problems some people encounter is writing launch scripts. The best way to handle this is the Entry Points mechanism of Setuptools, and a file. It’s quite easy to implement. If you’re interested, read on to learn more!

  • Unix locales vs Unicode (‘ascii’ codec can’t encode character…)

    Topic: Locale support/Unicode Platform: Unix (Linux, macOS, etc.)

    You might get unusual errors about Unicode and inability to convert to ASCII. Programs might just crash at random. Those are often simple to fix — all you need is correct locale configuration.

  • Structuring and automating a Python project with the Python Project Template

    Topic: Python Platform: any platform

    To create a project that other people can use and contribute to, you need to follow a specific directory structure. Moreover, releasing a new version should be as simple and painless as possible. For my projects, I use a template that has the structure already in place, and comes with automation for almost every part of a release.

  • Adventures in Windows: Music Player Daemon

    Topic: MPD Platform: Windows

    Recently, I had to reinstall Windows. One of the things I had to set up was MPD, the Music Player Daemon.

    This is a short guide on how to do this.
