Ok, so I finally got my own domain and hosting to put my stuff without worrying about letting my own machine running 24/7 with dynamic ip address and dns resolution.
For the moment I’m hosting it at DreamHost. It’s not that expensive and it let you access it by a ssh connection (on a debian machine).
I already got my own git repositories :-), by using it with webdav, quite easy to set it up.
Now it’s easier to share anything I want, and with git everything it’s even easier ;-).
