Following the celebration of my 20 years with Linux, I wanted to recreate the moment I installed Ubuntu “Breezy Badger” 5.10 for the first time, and with QEMU it was quite easy to do on my modern Fedora 44 environment of 2026. Install and Run First of all I downloaded the install CD for i386 of that old release,...
Ah, so you think I’m going to talk about the dance called Tango; but no, this time I’m going to talk about an album called “Tango”, by those two towering figures of Argentine rock, namely Charly García and Pedro Aznar. Now, you’re reading this and you’re probably asking yourself, why? As Simon Sinek once said, start...
So here is a new project on GitLab called NeXTClock: a small browser-based recreation of a NeXTSTEP-style clock applet from the 1990s. This modern version renders a 64-unit clock face into a square <canvas> using JavaScript and requestAnimationFrame(), with optional scaling from 64 to 500 pixels, because, well, Java...
Regular readers of this blog know that I’ve been quite a happy user of Cursor for the past year, but the recent news of its mother company being purchased by SpaceX has made me reconsider my decision, and cancel my current subscription altogether. The same way I don’t have a Twitter account anymore, or I don’t own...
At this point it’s becoming increasingly clear that I can ask Cursor to read any of the implementations of my Conway and translate that into any other programming language that I want; this is what I’ve done last year with NASM, Scala, and Bash, and this year with Haskell. Yes, I have read Miran Lipovača’s...
Call me late to the party if you want, but I recently adopted Neovim as my new full-time text editor for work, and I have to say I’m very pleased of having done so. In case you don’t know (which given my audience, I’d be surprised to hear) Neovim is a successor of Vim, built since 2014 on a fork of version 7 point...
I always share stuff from Argentina, but after listening to this song you might want to head towards Brazil instead. I’ve been listening to it in a loop for the last few days. It’s like having a streaming service of sunny weather in your ears. I thought you could use some sun, too. It struck a chord in me. It made...
How do we secure massive, complex supply chains without slowing your developers down to a crawl? This talk provides a simple preview to Red Hat’s Trusted Software Supply Chain, based on three pillars: Transparency through the Trusted Profile Analyzer; Identity, thanks to the Trusted Artifact Signer; and Guardrails,...
Let me tell you the story of what was sounding in Buenos Aires’ FM radios almost exactly 40 years ago. “Oktubre”, by “Patricio Rey y los Redonditos de Ricota” released in its entirety in October 1986, is widely considered to be one of the greatest albums of Argentine rock of all time. During that year they released...
Three years ago I wrote about a workflow to generate PDF files out of my Markdown content, both on this website and on De Programmatica Ipsum. That first setup involved Pandoc and TeX, and it was a solution that worked well, but was unfortunately slow as hell, particularly given the amount of articles I have in both...
In this blog I’ve often mentioned the name of my late friend Bertrand Dufresne, who passed away 10 years ago this year. Despite all the good memories I have with him, I wanted to remember him through an object he offered me once. The eiPott was this short-lived thingy made by Koziol in 2010: a small, colorful...
This year I decided to treat myself with a new keyboard, and I’ve chosen the Keychron Q3 Max; this post is a short summary of my impressions after a few weeks of use. To begin with, the mandatory TL;DR: I love it. There is no way to put it; this is by far the best keyboard I have ever owned, and I cannot believe I...
