I have switched to using fossil SCM for managing the source code of this website. I am attracted to the idea of having a decentralized store not only for code but also for tickets, wiki, forums / chat, etc etc. Basically everything github provides, but capable of offline working.
Fossil is quite different to git, so I expect some learning curve. Starting with my own personal site is easy enough. I also have fossil running as a server on code.mfashby.net, and I might try to convert the old github repository into a mirror of the fossil.
