I'm very excited about the Java track at Devoxx Belgium (devoxx.be). This is real content, from human core developers who *understand* what they are doing. It helps understanding how and why Java works the way it does. If you want improve your developer skills, I recommend joining. #java

Java verbosity is cheap. Ambiguity is expensive. A clarifying question from a coding agent costs a full round trip. A record, a sealed interface or a Bean Validation annotation costs a few tokens, and javac verifies it for free. Six points 👉 adambien.blog/roller/java_... #java #airhacks

After a day of interacting with German web sites, I am reminded of Hanlon's razor (en.wikipedia.or...: "Never attribute to malice that which is adequately explained by stupidity." Or it's corollary, Grey's law: "Any sufficiently advanced incompetence is indistinguishable from malice."

Looking for input/feedback from Java developers on 2 different topics: 1. Is there interest in a JavaFX workshop/conference/training in Belgium? 2. Is there interest in a gathering with fellow Java developers working on scientific topics (writing java code, not only using 3th party code) #java

IMO the quality of #Java has improved *a lot* between 2015 and 2025 -- excellent work of the heroes at #OpenJDK. As for the #community, I hope we can get more diverse. One of the great things in the early days was "Java Everywhere". Think about education, science, data/embedded,... #innovation

All folks who speak at conferences should read this and think long and hard about whether they want to risk speak in the US in the future. Also anyone who works while traveling. comicon.com/2025/03/18/f...
First of all, they all confirmed what I thought.
The majority of comics creators travel to the
USA on an ESTA — "The short is that almost everyone just goes in on a ESTA. "That's the electronic tourist visa, easy to apply for, valid for two years. Things are slightly different for Canada, they have their own version of an ESTA, and anecdotal reports say that some Canadian shows implicitly include visa requirements in the guest information.
But when you're going in on a tourist visa like the ESTA, the Immigration and Border Control can and will interrogate you about what you're visiting for. And if they have even the slightest idea that you're working whilst you're there, they can and will deny you entry and/or detain
you.
The problem now is that all those previously accepted and overlooked things that can be classed as 'working', such as Becky's chores for board or a hotel room for a comics convention
in return for your appearance, could well see you denied and/or detained.

This project is key to Java. We need a notebook to bring Java towards students, scientists,... and help them doing research/POC's in the same language that can later be used in production systems where performance/stability/scaling/security is key.

Apache NetBeans is the only IDE I use. I know it is less popular than a few others, but it somehow feels as it respects me as a developer. That's something I miss in other IDE's, which often give me a feeling of "Trust me, I know (better than you) what you want to do".
