This Sunday I gave a talk at a conference and someone came to me afterwards telling me that my posts played a part in politicizing them. Still thinking about that. A lot of the time it feels like one is just yelling at the clouds but we can sometimes make a difference in each others' lives.

May I hold up the mirror a bit more? DevRel: most report into marketing. Which means they do marketing, aka the stuff they produce is there primarily to sell more products/services. Also: DevRel mostly writes sample apps, not production-grade. All tech looks awesome when writing hello-world apps.

JavaFX is back — now part of the Java Verified Portfolio. Proper support again across Java versions. Big for desktop apps. Modern Java can do way more than people think — even AI and full stack with fewer moving parts. Also: great hallway track, Brian Goetz, Stuart Marks, and Duke 🙂

Excellent read. A sufficiently detailed spec is not far from code. I wouldn't be surprised to see a formal grammar for specs emerge, at which point we'll just have invented a higher level programming language or reinvented MDA. And then we'll just need a compiler, not an LLM.

Can't wait for the loosened up, non-perfect, but quickly shipped AI-enhanced updates to hit my banking and insurance services next year. Im sure there will be no issues there at all.
software development in 2026 is going to require some to loosen up a little
code doesn't have to be as perfectly crafted the way we did it pre-ai
call it slop if you want, but if you're still demanding perfection on every pr while your competitors are shipping "slop" that works.. you're fighting from a disadvantaged position
shipping velocity matters more than perfection
