“I paid for 10 cores, I’m gonna use 10 cores!”I set out today for a silly explore hoping to waste some CPU with a whole bunch of ractors doing math, but I find that YJIT is pretty amazing.Ruby 3.0.0 came out in December 2020, more than 4 years ago now, and with it came Ractors (and Fiber Scheduler but that’s another...

Recently, a ticket came across my desk asking for help with stopping people from using a free GPU service to mine cryptocurrencies. The tool they requested to do this was Falco, an eBPF-powered agent that runs in a Kubernetes cluster, watching for suspicious syscalls using a set of rules. To detect cryptomining, the...

This is the text underlying my presentation at OSDay 2025, held on 21 March 2025 in Florence, Italy. There was limited time, so I couldn't go into much detail and had to keep things more general and structured than usual. I was also a bit nervous because of that — and honestly, it wasn’t my best performance. My Engl...

I recently read A Philosophy of Software Design by John Ousterhout (of Tcl/Tk, Raft, Sprite fame). One of the core concepts explored in this book is the distinction between “deep” vs “shallow” modules (in the author’s terms a module is any kind of abstraction, separated into the user-facing interface and the underly...

After leaving the networking industry in 2013, I decided to replace the Cisco network equipment at home with Mikrotik for reasons of cost and power.

Recently, I heard someone complaining that "this language is so stupid. Why do I need to touch eight different files to add one checkbox?"Well, I don't know for sure, but I think it's probably not the language that caused it, it's probably a combination of the architecture of the solution and a misunderstanding of w...

I care about the performance of RavenDB. Enough that I would go to epic lengths to fix them.

As a backend developer whose frontend experience is mostly from using Phoenix and Django that utilize server-side rendering, I’m wondering why do most people choose React and JavaScript as the “default” frontend solution, even for pages and SaaS products that don’t really benefit from any additional client-side interactivity?
