This is a really useful collection of upgrades in a easily digestible format.

Time to open your mind to the #JVM or admit you're holding onto prejudice; these features are GPL, and a few, explicitly for you!

Proteus - Tapir-style #gRPC endpoints in #Scala, by Pierre Ricadat, just got #Ox integration for streaming responses! All in direct-style, leveraging #JVM's virtual threads.

Check it out :)

Just published: a real-time ISS tracker built with Java and Quarkus.

It streams live spacecraft position updates using Server-Sent Events, renders them with Qute, and runs entirely on the JVM.

Space + Java = always a good combination.

Ever wonder what your #JVM really sees? Most #Java devs ship code every day without knowing what the bytecode actually looks like — or how the #JDK tools interpret it.
Mahendra Rao breaks it down with javap & reveals what happens behind the curtain.

Less boilerplate sounds great. But are you trading it for hidden complexity? #PatternMatching adds power—and surprising pitfalls. @cayhorstmann dives into where it actually pays off.

What kills a technically solid #OpenSource project? Not bugs. Not architecture. Adoption. @verhas explains why his enterprise-grade documentation tool never found its audience & what developers actually want instead.

Java TLS has been a blind spot for eBPF-based #observability tools for years. JSSE runs entirely inside the JVM with no exported symbols and nothing to attach to.

Here is how to solve it: https://coroot.com/blog/java-tls-instrumentation-with-ebpf/

Benchmarking our eBPF Java TLS agent against OpenTelemetry, Coroot added only +15% CPU overhead vs +38% from OTEL, which dropped 20% of requests under load.
