I created my BitBucket account and started publishing some of my code.
So far I pushed two projects there:
Mercurial Keyring is a (newly written) Mercurial extension which uses keyring library (the same I have already been using in greader2org) to securely save HTTP and SMTP passwords. See the source or the wiki page for detailed description
mekk.xmind is a library which provides pure Python code for generation and parsing of XMind mind-maps. I wrote it while working on nozbe2xmind but it is of general use. The library is a bit rough (in particular, some comments and commit messages are written in Polish), I plan to polish it in the future.
I also hope to publish more code (in particular sources of the projects I described here) in the future.
