Konrad Hinsen's blog

How can we document software and computational analyses in such a way that others can convince themselves of their validity, and build on them for their own work? The question has been around for many years, and a number of attempts have been made to provide partial answers. This post provides a brief review and describes my own tentative answer, inviting you to play with it.

Issue 084: Spreadsheets

Welcome to the 84th issue of De Programmatica Ipsum, about Spreadsheets. In this edition, we declare spreadsheets the most popular software programming environment of all time; in the Library section, we learn how to use Lotus 1-2-3 for science reading "Spreadsheet Physics" by Charles Misner and Patrick Cooney; and in our Vidéothèque section, we discover that Excel is a Turing-complete, functional programming language through the eyes of Dr. Felienne Hermans.

On Long Term Software Development - Bert Hubert's writings

Recently the Dutch Electoral Board (where I am also a very part time advisor) invited me to do a talk reflecting on their open source Abacus vote tabulation software. Much software is now provided as a service, and is typically deployed continuously (CD, continuous deployment), surrounded by enough automated testing (CI, continuous integration) that we can be reasonably sure that a new revision is likely to at least work to some extent.

Old and new apps, via modern coding agents

I have been interested in machine-assisted ways to do and teach mathematics from as far back as 1999, when I started coding several applets in Java 1.0, both for my complex analysis and linear alge…
