I use pyenv for Python version mgmt and sometimes existing venvs are broken after patch update.

This weekend I spent some time improving Ansible playbooks to recreate venvs I work on every time new version is installed through pyenv. I'm pretty happy how it turned out!

High Volume Automated Testing is not discussed often, but I wanted to try one ever since I learned about them. I go through design decision points in the latest article on my blog:

Is there a community consensus around Wordpress state today? Did we move to something else (fork or not)? Did we say everything's fine? Is it still brewing?

Did you know that when doing interactive git rebase, you can pick any commit from any branch? It’s obvious when you think about it, but you would be excused for doubting it.

A fellow engineer was uncertain how they should spend their limited time - should they test the new thing and work on automation later, possibly after the release? My answer is on the blog:

A fellow engineer submitted a question to internal mailing list. The gist is: a new feature is supposed to be released in a few months and there is no automation coverage for it. What should a person ...

In this post I will discuss a few key points that have mattered to me, and setting my context, in different companies and teams.

Now that poetry supports PEP-621, I spent couple of hours updating all my projects to be compatible. In case of Pelican plugins, that also meant aligning to current community tooling baseline, which involved fixing a number of issues that ruff complains about.
