I've just switch the mgautier.fr backend to Pelican.
Until now, Drupal was the CMS of the website. However, regarding the number of posts and the number of Drupal updates, I was updating Drupal more often than I was writing post. So I switch to Pelican.
Pelican is a "small" soft written in Python generating static websites from content wrote in markdown of reStructuredText syntax. Finally, there is an output directory containing static content. No script, no PHP and no update :)
The only drawback ? It is static :) So, there is no commentary system. But I've got some idea to add them. Waiting them, you don't have the right to speak :P
