Languages that try to disallow idiocy become themselves idiotic. — Rob Pike

For the first time I paid to have a work of art professionally framed. For django-cast, the work on separating the data fetching from rendering the content is almost done, so I moved on to the next interesting problem. As the saying goes: To make an easy change, first make the change easy (which was really difficult) and then forget about the easy change and do something completely different because it's not challenging anymore. At least I managed to get the changes I made so far into a new release.

• One of the things about charlatans is that we—oops, “they”—are an uninformed person’s idea of a genius 🧵
• Today at @answerdotai we've got something new for you: FSDP/QDoRA. We've tested it with @AIatMeta Llama3 and the results blow away anything we've seen before. I believe that this combination is likely to create better task-specific models than anything else at any cost. 🧵

Einstein repeatedly argued that there must be simplified explanations of nature, because God is not capricious or arbitrary. No such faith comforts the software engineer. --Fred Brooks

I had a lot of fun recording a podcast episode about DevOps. Then there was this month's Django Cologne user group meeting and I talked to a lot of nice people. Somebody has to build a RAG website for the Django documentation, please! The next day the Python User Group Düsseldorf met, which was also really interesting.

During the week I worked a bit on django-cast, trying to cleanly separate database access from template rendering, which is still going on and more difficult than I expected. But I got some comfort from listening to a Django Chat episode about Kraken where Çağıl talked about how they use dataclasses (or some other kind of value objects) to render their templates to avoid having database operations going on during template rendering. Seems they face similar problems over there.

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 🌸.
