After several months of waiting, the git repository and gitweb for the site are finally installed. For now, you will find two OpenERP modules that will serve as the basis for tutorials. In the future, all my projects that will be open-sourced will be found there.
Here is the link to access the gitweb, which allows you to browse the various projects, see diffs and branches, and here is how to clone one of the projects:
$ git clone http://git.inspyration.org/OpenERP/todolist.git
And finally, here is a mini-tutorial on using git.
