Blog Cosmoscalibur

Welcome to my blog, Cosmoscalibur.

This is a space to share about different topics, not only popular science content. Mainly, there are posts about science, technology and my own poems, but over time this may change following a pattern of curious items I want to share or personal notes that serve as reminders.

About me, you can learn more at Edward Villegas

My latest posts are listed below, but you can see the full list at Posts.

  • (2026-03-23) Rust Ecosystem for the Linux terminal

    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).

  • (2026-03-07) Agent Readiness Framework for Coding Projects

    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.

  • (2026-02-24) Best practices in Google Colab for sharing with non-technical teams

    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 always falls on the technical team.

  • (2026-02-23) Prompt Engineering: Technical Skill or Scam?

    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?

  • (2026-02-22) Seekee: free alternative to watch movies and series

    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.
