Pandoc vs. Pandemic
While things were shifting away from away from keyboard, I found little pleasures in seeing software tools in production. Most of all I enjoy small scripts1 that take a few lines of readable text and turn it into a website for an online course, into lecture notes, or a slide deck for presentation.

Adjoint Systems for Optimal Control from Pontryagin to Wikipedia
While it seems common knowledge how to formulate necessary optimality conditions backed by the famous Pontryagin’s Maximum Principle, the direct derivation from the very general original formulations is not obvious. Sometimes, authors like me1 provide some plausibility like obviously this term has to vanish, refer to other sources that miss the derivation too, or attach the complete book by Pontryagin to a specific formula2.
