Java profiling in Coroot now covers memory allocations and lock contention. It requires no code changes, no JVM flags, and works with any HotSpot JVM: https://coroot.com/blog/java-profiling-with-async-profiler/

Enable it with a single environment variable for flamegraphs and time-series metrics. Learn how to set it up #opensource on your system.

I worked on `kubectl rustnet`

It creates an ephemeral pod running full TUI with eBPF process attribution, deep packet inspection for 21+ protocols, and automatic cleanup when you're done.

No sidecar, no DaemonSet, no leftover resources.

Working on what's next: resolving pod names and container IDs so you can see exactly which workload is generating that traffic.

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:

Zum Code geht's hier entlang:

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