It's not plug-and-play. It still needs a custom firmware:
"(...)The presented methods allow us to deploy a custom SEV firmware on the AMD-SP, which enables an adversary to decrypt a VM's memory.(..)"
Voltage glitching is no double-click. It would be a huge embarrassment to AMD if just double-click defeated the secure processor's firmware authentication. This requires electrically messing with the power supply of the processor.
So this means the secure VM feature is secure up to the threat model of someone able to crack open the hardware.
Honestly that's kind of what I would have expected. Just making it almost impossible to get VM memory remotely by owning the hypervisor is pretty good and reduces your attack surface to people who can get into the data center and have electronics expertise.
In this summer, for my vacations, I've decided to re-read several of sci-fi books, with some popular new ones, and opted for a ebook reader (kindle) to avoid carring several pounds of books to the beach. Started with Isaac Azimov's Foundation triology (all), made a jump to William Gibson's Neuromancer and now, just ended Frank Herbert's Dune (1st volume only).
Coincidence is seeing this article just after returning from the vacation's, still imagining riding on a Shai-Hulud.
The only true comment that would like to add to this thread regarding Blanch's "The Sabre Paradise" is something that I've heard from an old teacher: most, probably all the books are derived from Homer's Odyssey; which created most of the writing styles, characters constructions and interactions, world creations, etc. After, there's not a single book that brought anything new to the writing, except the way you mix or the characters that you replace.
But even with this idea in mind, we cannot say that reading Homer's Odyssey means that you've read ALL the books, and there isn't not even that this is the best of books. To be honest I like the imagination created by it, but it's real "drag" if you try reading it...
At the end, for me at least, what counts is the mood: I prefer Dune over "The Sabre Paradise", the same way that I prefer J.R.Talkien's Lord of the Rings over "All Quiets on Western Front", even if both are based on the developments of the Great World War (I).
If you have time (and mood) read'em all... But still, keep away from "Odyssey" (there are a lot of more fun versions of the same story)! :)
PS: My next books in line are the (new for me) "Hyperion" and "Three Body Problem" from Liu Cixin. And recommended detours? :)
My opinion is to read 3 body problem first and complete the trilogy. I like Hyperion and read all the series but found each subsequent book less satisfying than the last (kind of like reading the sequels to Ender's Game). On the other hand, the series by Cixin gets even better after the first.
Have you read The Sparrow or any of Ted Chiang's short stories?
I read Chiang's Exhalation [0] prompted by your question. So much story in so few (6505) words! Great use of a crafted universe to tell a story relevant to us. That's the beauty of sci-fi as I understand it. Worth the 30 minutes.
Just want to add that the Three Body Problem trilogy is exceptionally good. The first book is the slowest, so make sure you read the other two as well. Each one builds up on the last.
