Where have all the files gone, long-time passing?
or everything you know about content versioning is wrong
1 A presentation on the history, current state, and vision for a better future of filesystems for the non-technical user. 2 How people loose metadata and how they preserve it. 3 How the GNU/Linux community may improve the situation. 4 Room for discussion of personal experience with these topics, and sharing of ideas for making life easier.
