Another xcover release: 0.5.0 🚀
🔎 Go binaries: automatic tracing scoped to the Go module
🪲 Stripped binaries: support for companion debug files via external .symtab fallback to DWARF - thanks @toabctl@fosstodon.org for your first contribution! 🎉

I'm excited to share that I'll be speaking at the @OpenSouthCode 2026.
I'll talk about cross-language coverage profiling using kernel instrumentation:
opensouthcode.org/conference…
If you're attending and are interested in runtime observability or eBPF, come and find me!

xcover 0.4.0 is out!
Support for stripped binaries has been introduced, among a latency benchmark, and other things.

👀 This is exactly why we created Chainguard Libraries. We can help! chainguard.dev/libraries

resurgo v0.4.0 is out.
github.com/maxgio92/resurgo/…
Accuracy numbers are starting to feel solid: up to 100% of function entries detected, with less than 1% false positives. Tested on Debian Trixie's grep 3.11-4, compiled with GCC 14.2, CF protection and fully stripped.

Was adding stripped binary support to #xcover with no debug info.
So I started playing with the Go disassembler and pulled the implementation out into #ResurGo: a Go library for prologue detection call site analysis, supporting x86_64 and ARM64.

Now #xcover supports stripped Go binaries. Take a look here: github.com/maxgio92/xcover?t…
I'll cut a new release soon.

Turns out you can communicate across containers via 63-bits of available space in a shared lock you acquire on /proc/self/ns/time that all processes have access to.
No networking required. The post has a demo of a chat app communicating across unprivileged containers.

Looking for a way to profile #coverage for functional tests transparently I built github.com/maxgio92/xcover
It generates a function clverage. Using #ebpf uprobes it supports ELF binaries and it's cross-language compatible.

I'm starting the eBPF verifier errors project, a collection of verifier error logs and their resolution, to make the verifier less scary, especially for new developers. It's a collection by the community for the community.

I’ve published the second part of a blog series about profiling with frame pointers.
In this episode you can read how to write a simple continuous #profiler with kernel instrumentation with #eBPF and #libbpfgo
