I find OOP philosophically unsound. It claims that everything is an object. Even if it is true it is not very interesting — saying that everything is an object is saying nothing at all. --Alexander Stepanov

Using Django, htmx, alpine.js and tailwind for work, which is a very powerful combination. Did some vacation planning and misplaced my keys. Discovered that it's super easy to replace an AirTag battery.

Treason doth never prosper, what's the reason? For if it prosper, none dare call it Treason. — John Harrington (1561-1612).

Took a closer look at neapolitan and liked it. But imho it's not so much about reusing code from CRUDView as a template for how to structure a couple of views that all share some common logic. Found out the hard way that it's surprisingly difficult to convert html to pdf.

Then the preschoolers said goodbye, but not much else happened besides work.

Interviewer: do you have an example of projects you spent too much effort on?

Me: I suppose the work on Mambo 1 to 4 was a bit of a waste... --Chris Heilmann

Wrote my first UI Tests using Playwright as a pytest plugin, because the UI I'm currently working on is quite javascript heavy. Overall it was a good experience. But it's hard to get the test browser to behave like the real one:

• Drag and drop just looks different (I have no idea why).
• Clicking on a link in the test browser results in href navigation, while clicking on the link in the real browser triggers hx-get

One of the projects I worked on last year went live: Plastic IQ tool launched in Brazil and Indonesia (link goes to Linkedin).

- where did he go?

A deep dive into htmx and Alpine.js. Mixing hyperscript in weird htmx attributes with javascript in even weirder alpine attributes embedded in already weird Django template syntax is often too much for PyCharm and djhtml. But it still works - so far I can't complain. A while ago, my printer broke down. I got a new one this week. I had to deal with some bureaucracy because the refund went to a bank account that no longer exists.

Another WWDC was held and some weird hardware got announced. But on the plus side, PWAs on Apple platforms finally seem to be getting interesting. So, yay for that. I went to a meeting of the local Python user group, which was a lot of fun. And finally, summer is here, so I spent a lot of time out in the sun, barbecuing, etc.

Slowly getting back to work, combining Tailwind and htmx with Django. Released a new version of django-cast which now includes all the information needed to run a SPA in front of it from a theme. This was more work than expected. To make sure there's all the information needed for a SPA theme, I built a Vue.js cast-vue theme for django-cast, which is now feature complete after adding comments and the podlove player for audio content last week. Also met with Manuel to work on training LLMs from scratch using all the Python code from GitHub.
