The list of things for the week doesn't seem to be any shorter, but there's only one day of proper-work left! (Tomorrow begins the Wikimedia Hackathon\footnote{\url{https://www.mediawiki.org/wiki/Wikimedia\_Hackathon\_2022}}.) The dramas I've been having with my rear gear shifting have been resolved, so at least that's good news. It seems my gut feeling was right: it felt like there was \emph{something} preventing the derailleur from springing outwards, but I couldn't figure it out. I lubed all cable sheaths, cleaned springs, pulled everything apart and put it back together clean and lubricated. But I'd underestimated the simplicity of the shifters (Microshift BS-A09 I think they are), and hadn't realised that it's actually perfectly correct to just \emph{loosen} the bolt a bit. This frees up the mechanism, and allows the derailleur full control. Everything is nice again now. \end{document}
