** Star Wars, and a year in review **
I tried to write a“ year in review” kinda post, but it got wicked melodramatic pretty fast. This year has been a slog…it really fucking sucked.

Rather than reflect on it further, I thought I’d write about something vapid that I’ve been thinking a bit about lately instead: Star Wars.

Despite my best efforts, I’ve always loved Star Wars. As a child I spent hundreds of hours pouring over novels, and comics, and books of sch … ⌘ Read more

Paul Schaub: PGPainless 1.0.0 Released!
Close to the end of 2021 I’m excited to announce the release of PGPainless version 1.0.0! After a series of release candidates, it is finally time to party! The OpenPGP library successfully underwent a security audit in late November and I feel like it finally reached a state of sufficient maturity to be worthy of a major release with a “1” at the front.

Peter Saint-Andre: Meditations on Bach #9: Musical Monadology
In meditation #7 of this series, I took note of some similarities between the aesthetics of Aristotle and the music of Bach. Another intriguing influence might be the monadology of Gottfried Wilhelm Leibniz (1646-1716), who directly influenced philosophers and musical theorists in the Bach’s orbit: for instance, Bach’s student Lorenz Mizler (1711-1778) was a follower of the Leibniz scholar Christian Wolff (1679-1754).
