Last week, I attended an excellent JUG meetup! The attendance at Poznan JUG was great, and the discussions were engaging. The theater venue was simply superb. I'm glad I had the opportunity to share some thoughts on #VirtualThreads and the @helidon-io.bsky.social .

A nice run around the islands of #JavaCro with @kec.bsky.social #runWithJakartaEE #EclipseFoundation #Community #JakartaEE

Right time, right place to be for #jugtoberfest! #poznanjug

Another @czjug.bsky.social in progress together with #KBTechMeet. Starting with Jirka Pinkas and his talk about DDD.

Just learned at #geecon that @adambien.blog never worked!

We just integrated a performance improvement to Java String that will provide a ~10x performance boost in some applications where Strings are used as keys and where the associated values are constant foldable. This will make JDK 25 faster. github.com/openjdk/jdk/...
