One of the new features of Mac OS X Leopard is the Time Machine, this new feature allow the users go back in time and recover deleted files and configurations. Now is possible to have a similar feature in Linux with Flyback.
Flyback is a snapshot-based backup tool based on rsync It creates successive backup directories mirroring the files you wish to backup, but hard-links unchanged files to the previous backup. This prevents wasting disk space while providing you with full access to all your files without any sort of recovery program. If your machine crashes, just move your external drive to your new machine and copy the latest backup using whatever file browser you normally use. Flyback have a simple GUI build with GTK, the OpenGL view of the directories like “Apple TIme Machine” will be a future work.

To install Flyback under Ubuntu you need the following packages : python-glade2 python-gnome2 python-gconf rsync.

After all dependencies are satisfied just extract the program, go the the new directory and run python .

Time Magazine write a article about the best inventions of the year. The top invention is the somewhat well-known iPhone, but there are some extremely cool projects included that I had certainly never heard of, including a device for capturing waste heat from car engines to increase efficiency up to 40%, a novel car designed to run entirely on compressed air claiming to have a range of 2000km with zero pollution, a James Bond style GPS tracking device that police can use to avoid high-speed chases, a small-scale printing press capable of printing and binding a paperback book in 3 minutes for under € 2/book, a microbe-based technology for turning soft sand into sandstone, a water-based display which uses computer controlled nozzles to produce coherent gaps in the water, and a way to convert type A, B, and AB-negative blood into type O.

Timer Applet

When we are working sometimes we forget to do something, we need to put a reminder to avoid this problem. Timer-applet is a small applet for the GNOME panel that does this for you. The applet takes the form of a small button sitting on the GNOME panel. When you click it, the timer setup dialog box appears, and you can put some reminders there, once the chosen time period elapses, the applet notifies you with a bubble, and the button begins to flash. This little applet is very good to put timers, reminding to rest a little bit, after working a couple of hours.

Timer-applet is available in Debian since etch and in Ubuntu since dapper. Ubuntu gutsy features the 2.0 version of timer-applet which has a slightly better user interface, you just need to download the package and add it to the GNOME panel.

For KDE users exist Kalarm, with similar functionalities.
