Like before, this will be a mostly personal ramble about things that happened during the year. You’ve been warned. For the usual technical content, please tune in next year. The elephant in the room Let’s just get this out of the way: this year has been absolute rubbish. There’s no going around or sugar coating […]

This article is also available as a talk, check out the slides and recordings here. Introduction While the focus of this article is libraries, everything here applies to any project that has multiple modules.
