A Calustra

It was early 2017, and I was working remotely as a software developer for a company in London.

One of the things that's been worrying me about the current AI landscape is how we handle tools, or MCP, if you prefer.

As 2025 draws to a close, I find myself reflecting on what has been an extraordinary year, incredible in ways I never could have anticipated and at the same time, one of the most difficult periods of my life.

I've been experimenting with dictation for a while now.

It was about a year ago when I was lying in a hospital bed.

Over the years, I've tried to understand how companies work.

A little while ago I finished up a personal project that made me genuinely happy.

Everyone’s talking about AI and large language models (LLMs).

The other day, I was chatting with a friend about design patterns and realized that we often use them without knowing their formal names.

It's been an exciting few weeks for the European Space Agency!

This week the Biomass satellite was launched, one of the most ambitious Earth observation missions by the ESA.

One of the things that I considered easy was working with IMU (Inertial Measurement Unit), but I have found a few challenges.

It was the 19th of November.

I did not attend college, so I learned a lot of things on my own.

I've been working with embedded Rust for a while now, and there's one thing that keeps coming back to bite me - debug visibility.

I really enjoyed this Carlos Sainz interview, where he talks about sports, parenthood, perseverance, winning, and losing.

A Industriosa é un espazo único que moitos apreciamos profundamente.

Recently I've read a lot of security-related stuff, mainly because of the awesome 38C3 conference.

The world of media and Linux got a major update over the last few years thanks to the work done in Pipewire.

This year has been a journey of resilience, marked by two surgeries and multiple recovery periods.

I’m currently on my second tumor recovery, and, as in the past, I need to spend most of my time lying in bed.

Over the last months, I've been working with LLMs full-time.

When I tried to use the national certificate, I was unable to do so due to the encryption algorithm.

I had the privilege of attending PyConEs, the largest tech conference in my town.

A year ago, I was leaving the oncologist's office; everything was dark!

This week, I was with a friend whose team had an issue with the measurement of an acoustic device, so he asked for advice from a former manager.

I went to an awesome workshop at our local hackspace about Google Gemini and function calling.

Over the past few years, I had weekly 1:1 meetings with my manager.

Lately, I've been using Nix more and more as a development platform.

For a couple of years, one project I have wanted to pursue is building a Lap Counter TV application for our local Slot Racing Club.

Have you heard of ESPHome?

Over the past few weeks, I have been immersing myself in mathematics and physics, while also exploring the latest advancements in GPU technologies and the broader world of computing.

A lot of people know me as the person full of notes and lists.

Recently, a good friend convinced me to dive into a book I initially approached with scepticism.

I have been using org-mode for a few years now.

The other day, I explained how to deploy a sandbox VM to develop Kernel modules written in Rust.

Life is a whirlwind, isn't it?

Pandas is one of these projects that you can only feel in love.

Writing a kernel module is something "almost" straightforward, it has been in there for years, and it's generally easy to work with.

The other day, I found myself in a situation where I needed to transmit data via LORA, and then, I realized I needed dynamic serialization for my data structures.

One of the most important aspects of programming in Rust is efficient debugging.

One of my hobbies has been extensively working with Rust in embedded development.

As every year, the first week of February, Fosdem took place.

My manager confirmed my promotion to Principal software engineer a few days ago.

European Union is pushing some money to all countries to develop infrastructure for the regions.

Embedded Rust is something that it's taken off over the last months.

Over the last few years, I have been jumping between multiple Golang projects within different teams.

Last week I was on a call with my internet provider, and surprisingly the agent started to offer me a revolutionary product, "health insurance", yes it was my telecom provider.

One of the best readings this year was Agassi's biography, "Open".

Pulpocon is, for me, one of the best conferences in Spain.
