Performing my own: Capriccio e Incrocio in La minore con arpeggi (da Josep Bigorra) 🎸
#guitar Alhambra (#spanish classical guitar)

I riff some #classical #music and Spanish tones with the Crossroads #arpeggio

In this video, I explore the haunting beauty of A minor, focusing on the transition between rapid-fire arpeggios and the "crossing" technique with beautiful tone and subtle touch, balancing the dark, #melancholic tones of A minor with rhythmic drive. 🎼

It is a sad day, at the same time I look back and realize the journey was beautiful and taught me a lot.

I am no longer running a 100% #guix system. I got tired of things breaking, being removed without warning or explanation, undocumented things, cryptic error messages.

I am but one person and cannot afford to debug stuff everyday.

I therefore took the pragmatic choice of scripting some things on top of #fedora and spread the risk, with #guix #nix #flatpak and #dnf packages.

oh man... i am still in pain from day 3 AOC 2025 🎄 ✨
but it works.... after scrapping my naive combinations approach (i was trying to compute 121 billion combinations and compare them, my computer glitched and shutdown haha) now i went with a greedy stack based comparison....

ok day 2 is in as well for the AOC 2025 🎄 ✨

this felt easier than day 1 to be honest

solved the first day 🎄 ✨
ok ok, this was a mindf*ck, the 1st day of advent of code 2025... need a break 🧠

but it's there, and under the 100 lines of code, also purely functional style, no mutations 🫧

done in Lisp (Guile Scheme)
it's also quite fast (much faster than my first naive list shifting idea)

hope I manage to solve ALL the challenges 😃

Olive CSS (v0.1.5) a Lisp powered utility class vanilla CSS framework that allows opinionated "Tailwind-like" syntax and custom optimized production builds - no JavaScript (all Guile Scheme λ )

https://codeberg.org/jjba23/olive-css

You can use this in any web project, it is vanilla CSS, and it serves as a kind-of drop-in replacement for Tailwind so the syntax is mostly transferrable.

A minimal, declarative setup for productive Rust 🦀 hacking on Emacs + Guix

https://jointhefreeworld.org/blog/articles/rust/simple-guix-emacs-rust-development-environment/index.html

I noticed there was a blatant lack of resources and documentation on this particular setup.

With a tiny manifest and a small Emacs configuration, you get a powerful, reproducible, elegant Rust development environment.
