For my non-tech followers, specifically my activist followers, you should know that the entire tech industry has been freaking out for the last 36 hours because pretty much all computers are now totally fucked.

It's not just Intel. Spectre is scarier and affects basically all out-of-order-execution cpu designs including modern ARM (Android & iOS phones), AMD, even some RISC-Vs.
-
Is that confirmed? Last I read, the researchers hadn't tested it that far.
-
AMD only confirms variation one is in effect (but patches are here) / variation two has near zero risk / variation three has zero risk. Just my 2cents
-
"Variant 1" in the P0 blog notation? That's the attack that makes any kind of JIT'd embedded language (JS, Lua, etc.) unsafe and is probably the most likely to be exploited in the wild right away.

All AMD processors suffer from a similar, slightly less obvious but no less ridiculously awful flaw.

Any idea if AMD processors are similarly vulnerable?
-
AMD corporate speculative-execution page states variation 1 is vulnerable variation 2 is near zero risk variation 3 is zero risk.
