The next conference was about GnomeZeitgeist . This is an app for easily find files in your computer but the method of search is based in the date when you work with this file. So you can find the file you open two weeks ago for example.
The other great new is that ebassi announce us in his conference about Clutter that the next week will be released the 1.0 version of clutter (API/ABI stable in 1.x). Wow !!
