Hello,
This is an idea a had some time ago. It might be a waste of time or it might
be a good idea, you decide.
A short description would be "continuous system hibernation". Say you are
running Firefox, writing an e-mail in mutt and compiling the next X.org
release. The power goes off, your computer crashes or something happens and
you lose everything you were doing (yes, sadly you haved saved your e-mail as
a draft yet).
The "continuous hibernation" is some kind of memory snapshots taken, say,
every 5 minutes. The next time your system starts after a crash, it'd say "oh
oh, looks like something went wrong" and offer you a list of the last N (for
instance, 4) snapshots and you can recover your system to the very same state
it was before power went off or your dog unplugged your CPU. It might even
ask you which individual applications you want to start from that snapshot:
maybe you don't want to start Quake 3.
Provided the implementation is fast enough and you have a large hard drive, it
might even allow you to say: "I want to restore the system to the same stage
it had on Monday, 11.04PM"
That's it. Please, shoot at the idea not at the idealist :-)
