Windows no ha sido históricamente el sistema operativo más amigable para instalar paquetes de manera rápida y centralizada. Durante años, la norma fue buscar un instalador .exe o .msi en una página web, descargarlo y seguir un asistente de instalación. Hoy en día, sin embargo, el ecosistema ha evolucionado y contamos con opciones robustas: WinGet, el gestor oficial de Microsoft, y…

Einstein’s relativity opened a new chapter in physics from his first notes in a treatise on the electrodynamics of light. Special relativity already raised a point that emphatically separates the new physics from traditional Newtonian physics, and that is the non-absolute conception of space and time.

Already in special relativity we find that at higher speeds time passes more slowly for us than…

Now that I use Manjaro instead of Ubuntu, one of the problems I encountered when adapting the development environment I use for work, is that the MySQL connector for Python MySQLdb depends on libmysqlclient-dev, which is not available in Manjaro. Here is how I solved the problem.

MySQL Connector

The database connector provides an interface to interact with databases from an application.…

Coding agents are here, and they are not going away. But after months of using them —Antigravity, AmpCode, Opencode, Zed’s built-in agent— I have reached an uncomfortable conclusion: the problem is usually not the agent, it is the project. A poorly prepared repository will defeat any agent, regardless of how advanced its underlying model is.

I wrote about context engineering before, and…

En equipos de trabajo donde conviven perfiles técnicos y no técnicos, es frecuente que el equipo técnico desarrolle _notebooks_ en Google Colab para procesos periódicos: reportes mensuales, análisis de datos, tareas recurrentes. El problema surge cuando estos procesos requieren ejecución periódica con pequeñas variaciones —un mes diferente, otro departamento, un nuevo archivo de entrada— y la…

In a previous post I talked about Stremio and Torrentio as the best free alternative to Netflix, and I still think it’s an excellent option, especially on a computer or Android TV. However, today I want to talk about Seekee , an alternative that has surprised me with its ease of use and its extensive content catalog.

What is Seekee?

Seekee is a free mobile app that lets you watch movies…

Si has instalado Antigravity o AmpCode en Windows 11 y te ha resultado imposible iniciar sesión, no eres el único. Este problema de autenticación es más común de lo que parece y las soluciones habituales no siempre funcionan. Te cuento cómo lo solucioné.

El problema

Al intentar iniciar sesión tanto en Antigravity como en AmpCode, el proceso de autenticación basado en el navegador no se…

In teams where technical and non-technical profiles coexist, it is common for the technical team to develop notebooks in Google Colab for periodic processes: monthly reports, data analysis, recurring tasks. The problem arises when these processes require periodic execution with small variations — a different month, another department, a new input file — and the responsibility of running them…

En una publicación anterior hablé de Stremio y Torrentio como la mejor alternativa gratuita a Netflix, y sigo pensando que es una excelente opción, especialmente si estás en computador o Android TV. Sin embargo, hoy quiero hablar de Seekee , una alternativa que me ha sorprendido por su facilidad de uso y su catálogo en español.

¿Qué es Seekee?

Seekee es una aplicación móvil gratuita que…

La ingeniería de prompt se vendió como la habilidad del futuro. Cursos, certificaciones, títulos de cargo, libros y hasta programas de posgrado surgieron alrededor de la idea de que saber cómo hablarle a una inteligencia artificial era una competencia técnica diferenciadora. Pero, ¿lo era realmente, o era solo un parche temporal a las limitaciones de los modelos de lenguaje?

El origen: un…

In recent years, a tool has become popular not only as a base for the data analytics ecosystem («data science» as some also call it) but also generally for Python development (scientific, web, or general purpose). This tool is Anaconda, which not only provides us with a cross-platform package distribution system, a main repository with broad cross-platform support (_default_ or _anaconda_…

Los agentes de código están aquí, y no van a irse. Pero después de meses usándolos —Antigravity, AmpCode, Opencode, el agente de Zed— he llegado a una conclusión incómoda: el problema no suele ser el agente, sino el proyecto. Un repositorio mal preparado derrota a cualquier agente, sin importar qué tan avanzado sea el modelo que tenga detrás.

If you’ve installed Antigravity or AmpCode on Windows 11 and found it impossible to log in, you’re not alone. This authentication issue is more common than it seems and the usual solutions don’t always work. Here’s how I solved it.

The Problem

When trying to log in to both Antigravity and AmpCode, the browser-based authentication process doesn’t complete. In Antigravity, the login screen…

Prompt engineering was sold as the skill of the future. Courses, certifications, job titles, books, and even graduate programs sprang up around the idea that knowing how to talk to an AI was a differentiating technical competency. But was it really, or was it just a temporary patch for the limitations of language models?

The Origin: A Patch for Deficient Models

To understand why prompt…

I’ve been using Manjaro for 7 months now, and I’ve become passionate about it. I like having new features quickly, without sacrificing stability (which happened to me in my attempts with Arch Linux), its hardware and Linux kernels manager seem like very good utilities to me. In addition, pamac is a very useful tool to manage packages in Manjaro, much more friendly than pacman from…

Almost two years ago I set out to learn Rust, but I didn’t have time or really lacked the discipline to keep going. Now, I am firmly committed to this goal for 2025 and here I am taking notes, doing some exercises and starting a project. Regarding these notes, they should be considered personal notes, and well, I cover the basic details to start a project with _cargo_ , print to the console,…

Faced with the barrier of accessing specialized information, typically because it requires payment, there is a variety of open access alternatives.

In my days as a student, researcher and teacher, I had these limitations, and it was not always easy or quick to manage a resource through the library network when it was not available in the databases contracted by the university. As a result, the…

The best thing about growing up is not forgetting something fundamental: that we were also children once. Perhaps I think this now because sometimes, without realizing it, we can destroy the illusions that children weave around fantastic stories, which are the food for their creative capacity, and we, being older and «knowing» how things are, tear down that magical world with two words: «DOESN’T…

Besides my personal interest in this language, I am also interested in the ecosystem of tools that have been developed in Rust for the Linux terminal and for supporting other programming languages (like its impact on Python, which is my main development language).

I previously told you about Starship, and next we are going to expand this universe of Rust possibilities for the Linux terminal.

Historically, Windows hasn’t been the most developer-friendly operating system when it comes to installing software quickly and centrally. For years, the default workflow was finding an .exe or .msi on a website, downloading it, and clicking through a setup wizard. Today, however, the ecosystem has matured. We now have solid options: WinGet, Microsoft’s official package manager, and…

For years, the Python ecosystem has grappled with the “two-language problem”: we write code in Python for its ergonomics, but when performance becomes critical, we drop down to C or C++. This transition has always been painful, introducing memory safety risks and considerable maintenance complexity. However, we are witnessing a paradigm shift. **Rust has become the new standard for building…

Recently, for work reasons I have had to work on Windows and that is why I had the need to look for a comfortable option to use Git on Windows, with support from Bash to which I am accustomed in Linux and with Python Anaconda recognized. Somehow, the minimum version of how to use Windows without dying trying.

Anaconda Python

The first thing is to proceed to install Anaconda Python from its…

Well, after some time I return with posts that are finally related to something other than technology. The motivation for this publication is the particular birthday message that my brother left me, which says:

Happy 28th! 28 is a perfect number, literally. Because of that it is also hexagonal and triangular. It is true that it is the second perfect number, but it is also the last one you will…

En mi artículo sobre el marco de preparación para agentes expliqué cómo evaluar y mejorar un repositorio para que los agentes de inteligencia artificial trabajen de forma efectiva. Pero preparar el entorno es solo la mitad del problema. La otra mitad es decirle al agente cómo comportarse dentro de ese entorno.

Después de meses usando agentes de código —Antigravity, AmpCode, Opencode— he…

In my article on the agent readiness framework I explained how to evaluate and improve a repository so AI agents can work effectively. But preparing the environment is only half the problem. The other half is telling the agent how to behave inside that environment.

After months of using coding agents —Antigravity, AmpCode, Opencode— I have noticed recurring error patterns that no linter…
