It’s great that Mac OS X will have DTrace built into Xcode, and Time Machine, a GUI that can show nifty views of your files going into the past. If you want to start exploring these technologies now then you should have a look at OpenSolaris.
We’ve got some excellent visualisation tools that use DTrace, and with the aid of the excellent ZFS, we’ve also got the ability for users to take
automatic snapshots of their files, and even a prototype of a GUI to view snapshots.
As I’ve said before, OpenSolaris is ready for your desktop now – you don’t have to wait for Mac OS X to see how these exciting new technologies could be applied in your day to day computer usage. That said, I really look forward to Apple’s participation in the OpenSolaris community – welcome aboard guys!
