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:

If you're attending and are interested in runtime observability or eBPF, come and find me!

Support for stripped binaries has been introduced, among a latency benchmark, and other things.

Chainguard Containers now supports 1st Party RPM compatibility for RHEL 9 and RHEL 10, and we're joining FINOS 🎉

Here's what it means for financial services: https://t.co/BIGDsLRW2j

@leodido Interesting! Do you patch the bytecode of the filter tail programs at runtime in order to filter l4 stuff like the ports?

[Chainguard ⛓️ @chainguard_dev]

@karpathy 👀 This is exactly why we created Chainguard Libraries. We can help! https://t.co/foJuoDoK7f

@antirez I agree. I am believing more and more that AI amplifies **everything**, good and bad patterns in the development lifecycle.

just picked up this bad boy. can't wait to write some software with it

resurgo v0.4.0 is out.

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.

[maxgio92 (@[email protected]) @maxgio92]

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.

[maxgio92 (@[email protected]) @maxgio92]

Now #xcover supports stripped Go binaries. Take a look here: https://t.co/kclmErMlzO
I'll cut a new release soon.

[maxgio92 (@[email protected]) @maxgio92]

@artuskg @antirez I was going to do the opposite turn, from alacrity. I'm curious, what are the reason for you to do so?

[maxgio92 (@[email protected]) @maxgio92]

@fntlnz @antirez Just in time for @fosdem

[maxgio92 (@[email protected]) @maxgio92]

@fntlnz Impressive. Good job 👏

[maxgio92 (@[email protected]) @maxgio92]

@parttimen3rd @confooca I wish I could be there 😲

[maxgio92 (@[email protected]) @maxgio92]

@chiefnoah13 @ibuildthecloud TIL I've assumed it was possible on xorg as well. I'll never go back probably then lol

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.
