I think that Swift is an awesome language for functional programming! Many (functional) programmers don’t seem to know this. Hence, I gave talk about “Functional Programming in Swift” at @bobkonf.bsky.social — it is now online: media.ccc.de/v/bob11-2024...

Vandaag voelt een beetje als de dag na het eindexamen. Een gevoel van afsluiten en een moment van terugkijken op mooie herinneringen. Tegelijkertijd kijk ik vooruit, met nieuwsgierigheid naar wat komt. Na vier intensieve, mooie jaren is het tijd om afscheid te nemen van mijn plek in de Kamer. 1/5

It’s about positioning SwiftUI in the field of tension between MVC and model-view-update — for a good explanation of that field of tension, see https://dl.acm.org/doi/10.1145/3759163.3760429

This a big deal: "China’s carbon dioxide emissions have been flat or falling for 18 months"
China's economy has grown by ~5% in the last year, so this comprehensively debunks the idea (again) that emissions are tied to growth. So yes, faster progress needed, but this is how you turn the corner.

That chart is well worth studying. Share of daily transactions taking place in cash around the world. As an Australian, I’m very much used to cashless everything by now. I’m still totally against going fully cashless.

It seems that Banksy has just appeared in Lviv
We already know that in these difficult times, the world's most famous street artist has chosen Ukraine.
Art as resistance. Art as solidarity. Art as voice.
When the world watches, artists speak.
