It's been a while since I posted here, and at this point all of my previous posts have auto-deleted. Might as well reintroduce myself.

I am Gabriel, and I am based in Costa Rica. I work as an independent software developer and systems administrator.

As of late, my computer interests lie in #selfhosting, #Linux, and #containers. I care a lot about #privacy and ownership of our data and devices.

I am also passionate about #permaculture, #reading, #cycling, #fermentation, and #synthesizers.

My "Introduction to ICS Malware Analysis" workshop was accepted at the SANS ICS Security Summit.

You'll learn about ICS malware by analyzing samples modeled on FrostyGoop and CRASHOVERRIDE. No prior RE experience needed.

It's running twice: June 8 and June 10. Hope to see you there!

The coreutils Rust rewrite story is pretty funny.

Coreutils are tools like rm, mv, mkdir, etc. Unlike binutils, this isn't a fertile ground for memory safety bugs. But, the rewrite was completed, and in the spirit of progress, Canonical decided to switch.

But do you know what coreutils are a fertile ground for? Race conditions around file creation, deletion, permission setting, and so on. The original code accounted for decades of hard-learned lessons in that space. The Rust rewrite did not:

PS. I'm not dunking on Rust. It's just that... starting over from scratch has its hidden costs.

Reminder: de-skilling as a trend in software engineering was already in progress well before LLMs.

Toxic productivity culture, people meeting badly-designed internal reward metrics, hopping jobs and never seeing the consequences of bad choices, plummeting quality, short-termism.

Sure LLMs add fuel to this fire, but I’m not at all convinced they’re causal.

If anything, their popularity seems more a consequence of the culture than cause.
