About This Site Link to heading

This site was built entirely by hand, using 100% recycled (and free-range) electrons. On a more serious note, it was created entirely using free software—because free software is great. It is built, maintained, and hosted on various machines, all running Debian GNU/Linux. (For the curious: Emacs, Hugo, and Apache.)

Debian Link to heading

Debian is a project bringing together over a thousand developers worldwide who collaborate to create a universal free operating system: Debian GNU/Linux. They all share a commitment to the highest standards of quality, and Debian’s renowned stability makes it one of the very best distributions available.

Debian includes a vast array of software (about 70,000 packages), all integrated into a cohesive, reliable system that runs consistently across numerous hardware architectures.

Services

The range of services offered covers a broad spectrum of open-source computing. The following list is not exhaustive but provides an overview of what I offer. Naturally, other types of services are available upon request.

Development and customization Link to heading

A key characteristic of open-source software is its flexibility; it can be tailored to specific needs—such as integration into an existing infrastructure—or extended with new features where none previously existed. Such development and customization are not restricted to the software’s original authors and can therefore be handled by third parties.
