Johannes Bechberger @mostlynerdless.de · 22/04/2026Dear bluesky: Does anyone here work at #SAP and want to show off a cool #opensource project they work on (at least partially) on company time?

Johannes Bechberger @mostlynerdless.de · 26/02/2026I need your help: If anyone wants to send me an audio snippet saying "Boring" (as in "Java 26 is stable. It's boring."), I would happily accept them. I want to play this audio via a button press during a talk. In other news: I'm speaking at @amsterdam.voxxeddays.com with @lutskedev.bsky.social. 211

Johannes Bechberger @mostlynerdless.de · 02/12/2025I'm happy to announce that my meta-agent (a Java agent that instruments other Java agents) now has a nicer Web UI (thanks @hardcoding.fr): github.com/parttimenerd... 172

Johannes Bechberger @mostlynerdless.de · 07/07/2025RIP Java Applets. You made Java popular and helped it grow to what it is today. JEP 504: Remove the Applet API has been proposed to target (openjdk.org/jeps/504), so there will be no more applets with the next JDK (JDK 26). 03420
