I'm kind of surprised and amused that Ubuntu chose the name of a NBA expansion team (1980): http://en.wikipedia.org/wiki/Dallas_Mavericks

I'm kind of surprised and amused that the NBA expansion team chose the name of a surfing location in Northern California (1961): http://en.wikipedia.org/wiki/Mavericks_(location) ;)

..which was named after a dog. So I suppose in a round about way it is still named after an animal.

Not a lot of technical specificity around "memory compression". Edit: Ok, I stand corrected, somebody's done some research and found the code.

Windows 8 does a similar-sounding trick. At some timer interrupts they de-dupe pages and make them copy-on-write when they are identical. I seem to recall also reading that some VM products (VMware?) do this - so if you have a few instances of the same OS, only unique pages end up getting stored.

From the presentation I wonder if they're doing this, or if they might be putting the pages through a compression algorithm. (I hear "compression" and I think this, but it seems like that would make page faults needlessly costly.)

I really hope iCloud can be disabled in OSX-M. As far as I am concerned iCloud is a disaster. It causes all manner of data loss on iDevices, generally without the user having a choice. For example, my wife lost her entire calendar -all events- just for turning off calendar synchronization. All events had been originally entered through her phone. Somehow iCloud decided to delete anything that was also stored in the cloud, which meant everything. I really don't get the logic behind this behavior. It's really dumb. You never loose user data. So, I don't trust it now. I don't care to have anything to do with it.

From the pdf linked in another post below: They use WKdm, a very fast compression.

Lots of people are already doing this with 1Password either in iCloud or on Dropbox. As long as it's encrypted with the appropriate algorithms, what's the issue?

Yes or https://lastpass.com/ encrypted and free. Works wonders.

*free for desktop use; you do need to pay to use it on mobile.
