Wayland and Hybrid Graphics Issues in Linux
- 2024-12-18
Hybrid graphics cards are a strategy used by modern computers to incorporate two graphics cards: one integrated and one dedicated, with different capabilities and energy consumption. The idea is not to use the dedicated card unless necessary for 3D rendering. However, this is not a resolved issue in Linux and affects native applications running on Wayland, which is the new and modern protocol for server-side graphics communication used by window compositors in Linux (replacing X11), that utilize Vulkan.

“Distrohopping”: Switching Linux Distributions Without Losing Your Mind
- 2024-12-03
I’ve recently switched Linux distributions twice, which got me thinking about the associated effort and how it could be reduced. It also reminded me of the concept of “distrohopping” and the discussions about this practice, where many claim that it’s a waste of time and offers little value. However, I disagree and want to share the value I see in it and how to make it easier.

Recently, my girlfriend asked me to help her download the videos of a course before access to the account expired, and it involved downloading videos from Vimeo.

UV: A Fast Alternative to PIP and VENV
- 2024-06-30
UV is a package manager and virtual environment alternative for Python,
developed in Rust, which promises to be very fast in the processes it aims to
replace those of PIP and VENV. In this sense, all you need to do is add uv
before the usual instructions, and it should work (except for some particular
cases of compatibility or lack of implementation).

Creating Documentation for a Python Project with Sphinx
- 2020-01-06
Without a doubt, an important step in any development project (and not just software projects) is generating documentation. For software projects, it’s possible to rely on tools that help automate documentation generation by extracting comments from the code, using keywords and markup language to modify style in the text, or including other elements such as images, equations, and links.
Installing Packages in Linux (Mint)
- 2019-10-22
In Linux, we now have many more options for installing our favorite and daily-use programs according to personal interests in reducing disk space, increasing stability, improving security, always having the latest version, having very good integration with the operating system, or not requiring administrator permissions. Some of these strategies even make it possible to use the same mechanism across multiple Linux distributions, thus enabling a smoother transition.
