Akihiro Nishikawa is now discussing post-quantum cryptography migration at #JNation. #Java #Security #Cryptography #Coimbra

Luckily, I've had some great opportunities to speak at a bunch of conferences in Europe since February 2026, like Jfokus, JavaLand and Devoxx France. The next one is JNation in Coimbra, Portugal 🇵🇹. I'm not used to long-haul trips between Europe and Japan, though.

We are pleased to announce Micronaut 5.0.0-RC1 – a release candidate.  micronaut.io/2026/05/12/m... Please take a moment to try the milestone release and report any bugs before it goes GA within the next few weeks.  To help with upgrading, a migration guide is available. github.com/micronaut-pr...

Finished updating my slides for a conference in this month.

I am very much looking forward to attending #GraalVM Community Summit, which has an extremely interesting agenda!!

Automatic instrumentation can seem like magic—but it’s not! The latest #OpenTelemetry blog breaks down how it really works, from monkey patching and bytecode instrumentation to eBPF and runtime APIs. buff.ly/aWbGOzf

The presentation outline is finalized. The main line will not change after this, but I will need to gather updates on the topic to add to the outline until the day. And I've started practicing my presentation.

I'll talk at Devoxx Morocco 2025. Let me share migration strategy rather than how to use. See you there! devoxx.ma/speaker/?id=...

The itenerary is fixed to head to #JJUG_CCC after speaking at #Devoxx Morocco via RAK🛫MUC 🛫HND.
