See the Site Map for Mark's commercial and open source software, books, and short-form technical writing.
In view of the EU’s Cyber Resilience Act and an abundance of caution, I have withdrawn all my free software.

I am interested in the long defunct Personal Computer World magazine.

I use the Commit Mono font for coding and for my xterms. For typesetting and diagrams I used the Lout Typesetting System, although nowadays for typesetting I use asciidoctor.

I can be contacted via an “issue” at this website's github page.
