@bagder I have been wondering for a while now why people go on a rant about for instance Java and then add the hashtag #java to it. Doing that will bring it to the attention of people who are interested in Java and almost certainly not interested in their ranting.

So with me it gets them muted. Is that what they want? Or do they really expect to get a response by using that hashtag? 🤔

It makes no sense to me. But it certainly is handy for shaping my bubble by removing some jokers from it. 🥳

I have no idea if people still read blogs or just ask everything to AI. But I redesigned my blog and I am quite proud of the result. See https://www.wimdeblauwe.com/

There is now also a search to quickly find past articles. Give it a try and let me know what you think!

'Never use double for money' is dogma, not engineering.

Guest author Stefano Fago breaks down when double, BigDecimal, or fixed-point is the right call, and the production traps that quietly undo each one.

"XMLUI turns conventions into contracts. Component metadata defines the allowed props; markup defines the reactive graph; framework-owned components manage resource lifetimes. When programmers and their agents cannot use dangerous primitives, whole classes of mistakes vanish from the space of possible programs."

@jnkrtech Not specifically Spring, but solid and up-to-date book on #Java concurrency: https://www.oreilly.com/library/view/modern-concurrency-in/9781098165406/

Does anyone know of good introductions to #Java concurrency, specifically around thread pools, async, and #SpringBoot?

I’ve just joined a team which uses SpringBoot for gRPC microservices after spending my last 14 years in a single-threaded language. I’ve found a UDemy course which I might take but I’m wondering if anyone has other recommendations. I’m specifically *not* interested in just reading API documentation; I’ve been looking at it but I’m missing the thousand foot view and so nothing really fits together in context.

I have a CS degree and understand basic concepts like mutexes etc. already.

Here’s what I’m looking at buying next; I would love feedback on whether this is a good idea ahead of time:
