Read original comment ↗Holy shit, Christopher Domas is back. I remember watching his Defcon talks on x86 shenanigans[^1][^2] and being amazed at what he's been able to discover. Then he got whisked away by Intel and now drops this. I'm excited. [^1]: [VIDEO] [^2]: [LINK]
Read original comment ↗While somewhat interesting, I'm not sure there's much to discuss unless the presentation or details are already available.
