Did some cleanup after switching to the new wagtail-based django-cast for my homepage and python-podcast.de. Had to rename the users, backup, and remove the old services. Made sure the new backup is working. Then I deployed a self-hosted Mastodon instance and migrated my user there, which worked out well.

Went to the trivago Tech Get Together event to meet with friends and former co-workers. Had a lot of fun and heard about openpodcast.de - an open platform for podcast analytics, which is an interesting and promising project.

"Better to sink in boundless deeps, than float on vulgar shoals; and give me, ye gods, an utter wreck, if wreck I do." —Mardi

Lots of stuff happened last week besides work. After we finally found time to meet for some podcasting the week before last week, I finished producing our podcast episode about Python 3.11 😎.

Last week I wondered how long it will take to migrate the content after being able to deploy my new wagtail-based django-cast version. Turns out it didn't take that long, because now both this website and python-podcast.de are running the latest Python/Django/Wagtail combination. Ok, I have to admit it was a lot of work, and I broke some stuff, but now it's done. Finally 🍾! I started this project around 2019, so long ago that I don't even remember exactly when!

No images this week, I was busy sitting inside staring at computer screens.

Lots of stuff to do. Some of the projects I worked on last week:

Homepage

Since last week it's possible to deploy my homepage to staging using the new Wagtail-backed django-cast. I start to wonder how much effort it will be to migrate the content. In the old system, blog posts are just plain Django templates that are stored in the database and will be rendered upon request. This works fine but only if you fully trust the content editors, since they can inject arbitrary javascript code for example. But I want to use it to build a SaaS product and this would make it rather unpleasant I guess. In the new django-cast version I'll use the Wagtail CMS editor which should be safe to use for untrusted editors.

But now I need to convert all my template-based content to StreamField. Which seemed difficult at first, but then my lack of HTML knowledge saved the day: just throwing my old HTML content into a RichTextBlock living in a StreamField worked surprisingly well (see this: from legacy to wagtail conversion notebook). Seems like I can get away with just converting my custom template tags for images, galleries, videos and audio into proper StreamField blocks and keeping the rest of the html basically as it was. Sweet.

Django-Cast

Added a DELETE_WAGTAIL_IMAGES setting to be able to deactivate wagtail delete images physically to be able to test migrations.
This only works if cast happens to be placed behind wagtail in INSTALLED_APPS since Django has no way to call a function after all apps were installed. Video posters do now work with wagtail videos. The gallery modal now also works on the blog list page and not only on the post detail page.

Short work week. Gave me time to indulge in heavy yak shaving. At first, I tried to just make django-cast (the develop branch) work for newer Django and Wagtail versions. Then I realized I had to fix wagtail-srcset first and replaced poetry with flit while I'm at it. Then I got lost fixing some stuff in kptncook before I remembered that I have to also update django-indieweb and django-fileresponse to be able to finally fix django-cast and make it deployable on my staging system using the latest and greatest Django and Wagtail versions. Oh and then I fixed some bootstrap stuff in the commands.py of my Django startproject template. Maybe I'll manage to merge the develop branch of django-cast back into main soon after develop started to diverge back in 2019 iirc because I wanted to use Wagtail as a CMS. Looking forward to meet some hairy yaks on the way.

Spent quite some time fiddling around with my phone and Computers because of the iOS 16.1 / macOS 13 releases. Notes stopped syncing with my Macs (which happens with every major release). Reminders synced shared lists across different users and phones (wow, that usually also breaks on new releases), but it stopped syncing with my watch, so I had to take out my phone and look at it during grocery shopping (like an animal). I also tried out the eagerly awaited shared iCloud photo library, and ran into a lot of edge cases/bugs (the image and video counts stopped being accurate for me a while ago, but now they are just going crazy: edited images are converted to  tiff sometimes and then they cannot be uploaded to iCloud anymore and some images just refuse to be added to the shared library, etc pp). Maybe I have just too many notes, reminders, and photos.

Worked a little bit on django-cast to bring its dependencies up to date. There's a Wagtail RFC 71: support for responsive images that maybe makes my wagtail-srcset workaround obsolete. Would be cool if this is no longer needed. Planning to look into this in the next week.
