Wondering if there was a security thing with that wide-sweeping changes as #spectre/#meltdown; I don't remember any.
All OSes are scrambling to patch their kernels, browsers to patch their JITs and disable features (like threading), compilers adding flags to make virtual calls more expensive to mitigate, etc. etc.
Interesting and scary all at once :)
@jessehall Yeah, good question. Basically boils down to, do you want fast (everything that made CPUs faster in last 20 years, besides clock speed), or do you want secure?
I guess good thing is, things like Spectre don't affect majority of the code/programs. Only things that potentially cross privilege domains or "other things that should not be seen".
