Thierry, if/when you manage to revive any of your projects please add an image to show us what you are working on.

Re: loss of your old projects. It is a lesson to all of us that a copy or two of the data is NOT a backup. It is merely a copy and with our current technology you can lose that data at any time. Identifying and implementing a sufficient backup process is what is required and then adhering to it. All my old projects are making their way to github whether I find them useful/current/helpful or not. I no longer make the choice, I just stick everything on github and mark it obsolete/current as necessary.
