Imran Nazar recreated a JavaScript animation demo on 1982 hardware and wrote up every decision along the way: 6510 assembler, fixed-point math with no floating point available, a CPU bug turned into a cosine lookup. When he lands at 30fps, he can tell you exactly why without running it. It's very cool.
An essay from the creator of Primate argues that the JavaScript ecosystem traded cohesion for composition and has been paying for the seams ever since. The diagnosis reaches well past JavaScript: Java's own graveyard of JSF and GWT proves the seam problem is universal, and WebAssembly is about to make the question unavoidable for everyone.

Andi Roberts wrote up Alex Pentland's research on why some teams outperform others. The research is good; the practical advice mostly assumes a watercooler you may not have. Some additions from the trenches: what Brooks actually said, two cheap levers for building the idea flow, and when you want the opposite.

Reader Hideki Idoru argues that AI is a decent information distiller and a bad tool for nearly everything else in software, because no one can cheaply verify that generated code is correct. The deeper claim is that most programming was already trivial, unabstracted busywork, and AI has only torn the mask off. It's worth reading and thinking about.
Ray Myers wrote up the Bun rewrite and the fight around it. It's emotional in places, but there's real signal in it about how agentic work is sold versus how it's done, and one review technique worth stealing.
Java stripped out the SecurityManager and offered nothing in its place. Peter Firmstone's answer: fork Apache River and OpenJDK to bring back both JINI and JVM-level authorization. Laudable, even necessary - and a very hard sell, because it runs only on his JDK. It's like a post-mortem for JINI while it's still trying to breathe.
A Reddit user on r/SaaS is looking forward to the consulting rates he'll command once the wave of projects trying to dig out from under AI slop hits. He's not wrong, but he's dated the pattern to 2010 offshoring when it's older than that, and the lesson never sticks: coding was never typing.
Christian Rackerseder argues that the real axis for testing decisions isn't integration versus end-to-end, it's control: whether a team can make a dependency predictable enough for a given test and actually act when it fails.
Roseau, a new breaking-change detector for Java libraries, compares your code against your last released baseline and fails the build when the API contract breaks. JUnit already uses it. The reflex says the compiler and tests cover this, but if that were the case, updates would be easier than they are.
