The fallout from Meltdown and, especially, Spectre continues. This includes predictions that Moore's Law (exponential growth in computing power) will end: https://www.theregister.co.uk/2018/01/24/death_notice_for_moores_law/ Post-meeting exercises for <s>the reader</s> participants (based on talk): * How much physical RAM does your computer have? * How much 'swap' does your computer have? * Use lscpu (from `util-linux` package), or look in /proc/cpuinfo, to see what "flags" your CPU has? ** Which CPU flags are to do with memory virtualisation / isolation? (WARNING: time consuming question) * Run: uname -a to find your current running kernel. * Run zgrep CONFIG_PAGE_TABLE_ISOLATION -- /boot/config* to see if your running kernel has KPTI enabled. * Run the `spectre-meltdown-checker` to see what your computer's vulnerability level is. On Debian, can be installed via backports: ** https://packages.debian.org/stretch-backports/spectre-meltdown-checker *** https://backports.debian.org/Instructions/ Other topics discussed include the use of public Wi-Fi. The Mozilla Foundation has some safety advice on it: https://advocacy.mozilla.org/en-US/safety/public-wifi You might also want to checkout: * https://noscript.net/ * https://www.eff.org/https-everywhere * https://www.eff.org/observatory Any preference on next month's talk?
