On the road holding a Python training course. Didn't do much else.

Recorded and produced a new Podcast Episode about Ansible. Had to learn that streaming 48Khz 24bit FLAC audio to AirPods is too much for the Bluetooth bandwidth. At first, I thought the recording was broken, but then realized it was just a Bluetooth glitch, phew.

Did some preparation for a Python training course next week (setting up a JupyterHub instance, preparing a HedgeDoc installation).  Also, normal work as usual until we got evacuated because of a bomb disposal (a 500kg bomb from the second world war was found a few hundred meters down the street).

Software

• Excalidraw | Virtual whiteboard for sketching hand-drawn like diagrams. Collaborative and end-to-end encrypted.
• Donut on Hugging Face / Donut on GitHub | I've done things like this with tesseract getting much better results. But I'm really happy to see people starting to use transformers for problems like this. Very promising.

Podcasts

• WR1392 Strukturwandel ist teuer (WRINT Wirtschaftskunde) | Instead of raising the base rate (making investments to lower gas comsumption more difficult) or artificially lowering the gas price (providing an incentive to consume more gas) the rational economic way to handle a gas shortage would be to tax gas consumption. Of course this is not possible politically, but..
• #309 – John Carmack: Doom, Quake, VR, AGI, Programming, Video Games, and Rockets (Lex Fridman Podcast) | Good episode
• Pydantic v2 - The Plan (Talk Python To Me) | pydantic-core is completely written in rust, leading to smaller binaries compared to cython
• WR1390 China (Wer redet ist nicht tot) | Interesting, media coverage about Chinas social scoring is mainly creating a myth, etc..
• Jochen Distelmeyer (Reflektor) | Trying to listen to more music instead of podcasts - maybe I can start by just listening to podcasts about music, no?

Back to work. Picked up my jogging habit after having to stop during covid / vacation and it worked out fine. Made plans to get more into music again (atm just got more hardware).

• #35 test coverage is now at 100%
• #36 fixed some mypy issues
• #37 replace poetry with pip-tools
• #38 fixed showing multiple running deployments at the same time for tests
• #39 tried to speed up ansbile (mostly without success)
• #40 handling of exceptions raised during starting a deployment

For the last two weeks, I was on vacation, so no work. Seems my job is to listen to podcasts because there were significantly fewer episodes I listened to. Need to check with my boss 😄.

Had to learn the hard way that shared albums in apple photos are completely broken and will cripple your images (max width or height set to 2048px + conversion from heic to low quality jpeg). And even if you stop following a shared album, those broken images still sit in your library and you have to remove them manually one by one. Great fun if you just imported a few hundred photos from a shared album. I don't understand tech companies'  obsession with destroying their user's photos. Signal is bad, Whatsapp is worse, and now even you Apple? A working method for Apple devices is to generate an iCloud share link (which takes lots of time) from which others then can import the original photos.

Progress on having a landing page where people can create podcasts/blogs:

• Finished Add Email Backend for Registration Mails. This feature uses mailgun which is a pretty crappy service, if you've found a better one, please let me know.
• Add WordPress Ansible Service #28 moved the ansible folder over from podlove_test
• Cleaned up the register link and removed some unused code #30
• Use always _base.html in favor of base.html #31
• Added styled allauth templates #27

I've done one big vue project and lots of small htmx / Django projects in the last year and I feel much more productive using the latter. Learning Vue was always a hedge against being forced to use Javascript for web development, but the risk lowered substantially over the last year. But occasionally I still like to look at Vue content 😀.

Found a workaround for the fastdeploy / SQLAlchemy / asyncpg / Linux deadlock bug. I now instantiate a new SQLAlchemy engine on every request. That's probably not very efficient, since it would be better to use the engine's built-in ability to hold a connection pool, but having working code is a good start.

Progress on having a landing page where people can create podcasts/blogs:

• Finished Add remove domain / deployed fqdn #14
• Finished Switch between cast / wordpress #2 for deployments 🍾 - it was a complete surprise for me that this is even possible. But since I have now a working deployment system where all responsibilities are nicely separated, it's possible no not only to deploy Django, but anything including weird stuff like Wordpress without having to worry the rest of my system might suffer.
• Finished Fix pytest warnings + some cleanup stuff and coverage
