Website should be up, I just rebooted AWS :)
Oh don't do that. We have other shit running on it.

#12There's so much amazing stuff I could do with this. Imagine persistent redis? Huge huge pages? Booting from a DIM?
The possibilities are endless.

#16Why can't we just put a battery onto DRAM that maintains state if the power goes out, and be done with it?

We do on RAID cards. It has limits.

Because the power consumption to keep DRAM refreshed is fairly high so you'd need a pretty big battery, and because it would still be more expensive than 3DXP. It's just not practical for most use cases.

That is how storage worked on PDAs back in the day with volitile memory. Let's the batteries completely die or change them incorrectly and you lost your data. Let's not go back to those days!

#20It seems obvious in retrospect, but persistent memory adds a pretty exciting new advantage for persistent data structures.
Another thought: As potentially paradigm changing technology like this becomes available will it ever make sense to redesign the OS?
