    The best thing you as a user can do to protect yourself against #meltdown and #spectre is install an ad blocker. uBlock Origin, specifically.

    Practice good security hygiene, and you’ll have less to worry about when the next threat comes along.

    This post, on why the Raspberry Pi isn't susceptible to #Spectre or #Meltdown, is a wonderfully clear explanation of how they actually work: https://www.raspberrypi.org/blog/why-raspberry-pi-isnt-vulnerable-to-spectre-or-meltdown/ (via @Sangokuss)

    Aplico el parche de #Meltdown que baja el rendimiento un -30%, pero luego hago limpieza profunda de pelusas de polvo dentro de la caja de la CPU = +30% de rendimiento. Conclusión, me quedo como estaba. ?

    1. A Simple Explanation of the Differences Between Meltdown and Spectre
      from Daniel Miessler
      Many people have pinged me asking for a dead-simple explanation of the differences (and similarities) between these two attacks. Here's an extremely basic

    "To make the best use of the TLB, every mainstream operating system splits the range of virtual addresses into two. One half of the addresses is used for each program; the other half is used for the kernel."

    Basically, #Meltdown and #Spectre are exploits of what already is an exploit of the TLB design... Interesting stuff!

    Prediction:

    Software will be used to mitigate #meltdown and #spectre, slowing everything down.

    In 2020, a new line of Intel CPUs hit the market where you pay a premium for "virtual security extensions" (VSE) that let you turn off the mitigations.

    Google, AWS buy truckloads.

    Intel profites.

    Yay!

    Just FYI, the #OpenBSD project knew about the potential harm of #Spectre and #Meltdown 11 years ago

    https://marc.info/?l=openbsd-misc&m=118296441702631&w=2

    This is before exploits routinely started getting catchy names and even before MySpace was a thing. Let alone Twitter and Facebook was around to share news of the impending CPU apocalypse

    Too bad so few people listened
