Behind the scenes it moved from Apache httpd + mod_wsgi to nginx and uwsgi and from Debian Squeeze versions of the Python modules to the versions in Wheezy.
I started this new blog using the Nikola static site and blog generator. I really like writing this way (with my favourite editor, ReSTructured Text and git) instead of using some awkward browser based GUI. I chose Nikola over other alternatives because it's Python based.
I hope that I'll write a bit more often than I did in the past.
