On my way to Amsterdam

Habt ihr euch auch schonmal gefragt wo man `chown app 8080` eingeben kann damit der "app"-Account Exklusivzugriff auf #linux IP-Port 8080 bekommt?

Dann empfehle ich meinen frisch veröffentlichten #clt2026 Vortrag über mein #eBPF Projekt bindzwirn:
https://media.ccc.de/v/clt26-353-bindzwirn-linux-port-berechtigungen-per-ebpf

Zum Code geht's hier entlang:

Besonders jetzt, wo ich Version 1.0 vorbereite, würde ich mich sehr über Feedback freuen.

Bindzwirn is a really interesting project using eBPF

Java 26 is here, but it's boring. Nothing really exciting. But that's a good thing, as the boring stability is what made Java successful:

TIL: Removing the errorprone annotations package can reduce the JAR size by over 10MB (don't ask me why this package pulls in the google commons packages):

<dependency>
<groupId>com.google.errorprone</groupId>
<artifactId>error_prone_annotation</artifactId>
<version>2.40.0</version>
<scope>compile</scope>
</dependency>
