Architecture is a property of a system, not a description of its intended design --Stefan Tilkov

Had a week off, yay! Spent most of the time visiting museums, swimming pools and playgrounds. For open source, I'm still working on a performance-oriented refactoring of django-cast. This is much harder than expected. It's basically about being able to generate the html for all the performance critical pages like blog index, feed and post detail from a cachable data representation (serializable Python dict for example).

As a rule, software systems do not work well until they have been used, and have failed repeatedly, in real applications. — Dave Parnas

Last week working on SSO using django-saml2-auth. Didn't get much done besides work because the kids were sick and we were traveling a lot. Fixed a small bug in the post preview for django-cast. After I heard the latest core.py episode where Łukasz Langa asked if maybe someone could try to update python.org to a newer version of Django, I thought, ok, maybe I'll give it a try. But Jacob already submitted a PR 🚀, so I did a review instead. I also spent some time outside, the cherry trees over here are in bloom 🌸.

For open source, I

created a new django-cast release mainly fixing some bugs:

• Fixed a bug that caused the detail page link to be rendered twice on an episode detail page
• Fixed a caching bug in the feed generation that caused the wrong feed to be served
• Fixed broken galleries missing an id
• Fixed rendering of relative episode detail links for podcast feeds that were not clickable in podcast clients

Spent some time outside - this week had the first really warm days this year 🌤️.

Normal work week. Still catching up on my open source stuff:

• Finally released django-cast 0.2.28 which adds a way to provide all the data needed to render lists of posts without hitting the database. At the moment this is only used by the feed view, but more views will follow soon. And Wagtail 6 is now supported, while support for Wagtail 4 and Django < 4.2 is dropped.
• New kptncook release fixing a bug in the json export, thanks to @ton-An
• And a django-filepond release fixing some minor issues

Two weeks ago, I thought I had got my home network problems under control. But I was wrong - after my futile router and switch replacements, my wife's masterful Ethernet crimping skills finally fixed our home network problems.

Normal work week. Attended the PyDDF Python Spring Sprint which was great. I had to stop working on django-cast in January and used the Sprint to finally catch up. It's now possible to fetch all the data needed to render a list of pages (example: the feed) in one go and then pass that data to Wagtail, which then renders the pages without hitting the database. This opens up a lot of possibilities for performance improvements. The original plan was to work on a transcript feature, but this is fine too 😅. Adding transcripts is the next big feature on the list.

Mid-week I stumbled across this Mastodon post that forced me to indulge in some Vietnam travel nostalgia. I Went to an opera performance which was also great. And we released a new podcast episode about freelancing. Oh, and I managed to patch my favorite terminal font MonoLisa with some nerd font symbols because I finally started using Neovim again via LazyVim. Hmm, quite a busy week.
