This is a learning project for fun, but finally it works! github.com/maxgio92/yap Now it supports binaries compiled with frame pointers because they're currently essentials for the stack unwinding and doesn't supports stripped because the symbolization relies on the ELF symtab

man I work with nerds this is an ooo reply 🤣

My dangerous boredom, as Alessio Greggi called it, led me to this notebook notes.maxgio.me/notes/program-… about the #execution environment of a #program, while rethinking github.com/maxgio92/yap I could polish it to make it a blog 🤔 Should I?

I just published the first episode of a blog series. It dives into #frame pointers and their critical role in building a CPU #profiler. blog.maxgio.me/posts/unleashi… This episode will explore the fundamentals of a program's execution environment.

Single threaded languages 🙈

Massive JS library compromised

I needed a way to look into some documentation that apparently lacks a proper search function 👀 I ended up with github.com/maxgio92/wgrep 🔍 $ wgrep [-r] [-i] [—include=PATH] [—element=FILTER] PATTERN URL

I'm really digging the #Kubernetes builtin policy engine that went GA in v1.30. Checkout my guide on how to secure #FluxCD on multi-tenant clusters using validating admission policies written in CEL fluxcd.control-plane.io/guides/flux-po…

Andrew S. Tanenbaum, Vrije Universiteit, receives the ACM Software System Award for MINIX 🥰 Fun fact TIL, first Linux floppy had, as Minix had, “ast” account with password “watchwoord” that stands for “password” in Dutch. acm.org/media-center/2…

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 blog.maxgio.me/posts/unleashi…

Thank you 🤩

The video of my talk from the last #GoLab is now available! I shared insights on my side project harpoon and how to use it within test pipelines. Take a look and let me know your thoughts! youtube.com/watch?v=A5A_Ll… Link to the project: github.com/alegrey91/harp…

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. Read more about the project at mostlynerdless.de/blog/2025/01/1…

Every story begins with #!/usr/bin/env bash

BTW, I use Arch. 😜

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.

Writing good POSIX shell code is hard.
