Open Source

Software That Serves People

I believe software is at its best when it's open, shared, and built to serve people, not just companies. For me, open source isn't just a license; it's a philosophy about freedom, longevity, and putting the user first.

A lot of software today tries to nudge you into buying more or consuming content that benefits the vendor. I believe in building tools that do the opposite: they give you control. A simple podcast downloader, for example, should just download podcasts, without trying to sell you anything else. This respect for the user is at the heart of my approach.

A Simple, Open-Source RSS Podcast Fetcher

Tired of being constantly nudged toward "more relevant content", I built a script to break free from commercial or closed-source podcast apps. I just wanted a tool that quietly grabs my favorite shows—no fuss, no tracking, no extras. Read this post to learn more; it's free/libre software under GPLv3.

This philosophy also extends to making things last. In a world of planned obsolescence, free and open-source software can give old computers a new life. It's a powerful way to reduce waste and help bridge the digital divide by providing useful tools to everyone, regardless of their hardware.

Installing Debian GNU/Linux on an old laptop

This week a man brought his laptop to the community centre where I help people with computer problems as volunteer. The old laptop wouldn't start anymore and had to be reinstalled. Instead of Windows, I installed a free operating system. I think it is important to tell you how and why I did it.

This belief system is why I'm taking my biggest step yet by open-sourcing Gran Fondo, my app for runners and cyclists. In an industry where personal health data is a valuable commodity, I want to create a powerful, private, and completely transparent alternative that is owned by its community.

A Leap to Libre Fitness and Freedom

Gran Fondo, the app that tracks runs and rides, is going open-source. I’m removing its subscription model and make it libre. This isn’t about short-term revenue—it’s about building something enduring, private, and free for all. Here’s why I’m taking this plunge and what’s next.

This isn't a new idea for me. My commitment to open source began years ago, starting with simple but useful scripts that I shared freely with the world. It's a long-term belief that I continue to build on with every new project.

Backup Rotation Scheme

Rotate your backups with 'rsync-backup-rotator'

In today's digital age, safeguarding your data is paramount. Simply creating a copy of your files may not be enough as they can get corrupted, overwritten or blocked by ransomware. Having multiple, time-rotated (and ideally, offsite) backups is a stronger defense. I created a new tool, rsync-backup-rotator, to help you with this.
