    One consolation about Spectre & Meltdown. We've been hearing (a lot) about these vulns that will end life as we know it, but so far, (as far as I know), there has not been a single malicious example used in the wild, anywhere, any time, by anyone against anyone. The Y2K bug was lot more real and present and easy to demonstrate...
    I'm not saying they can't be used in the wild, but we've heard a hell of a lot about them, but after 4 or 5 months, there's still not been a single case of anyone catching gonorrhoea off a toilet seat.

    Spectre is incredibly impractical to exploit. It can really only be used effectively against task-specific machines since the standard home user machine has so much junk data. This supposedly makes it a very useful exploit to steal hashing addresses and wipe out crypto wallets though. Enterprise servers that process payments are ripe targets as well.

    If you have any old netbooks lying around from 2008-2011 or so, the models of Intel Atom processors those netbooks use are NOT affected by either Spectre or Meltdown. Just slap Linux on it to replace XP, and use that for the more security-sensitive tasks. That's one option, anyway.

    And who tells me that Intel didn´t know all along and they didn´t want to fix the problem for performance hit? What if AMD knew about it and they kept their CPUs more safe in the expense of performance? The biggest problem with Intel chips is that these vulnerabilities can be remote executed as were with AMD physical access to the computer is first needed to be exploited. But that´s all a theory for now...
