    [$] Control-flow integrity for the kernel
    Control-flow
    integrity
    (CFI) is a technique used to reduce the ability to
    redirect the execution of a program's code in attacker-specified ways. The
    Clang compiler has some features that can assist in maintaining
    control-flow integrity, which have been applied to the Android kernel. Kees
    Cook gave a talk about CFI for the Linux kernel at the recently concluded
    linux.conf.au in Gold Coast, Australia.

    [$] A tiny Python called Snek
    Keith Packard is no stranger to the linux.conf.au stage; he has spoken on a
    wide variety of topics since he started going to the conference in 2004
    (which was held in
    Adelaide, where organizers apparently had a lot of ice cream for
    attendees). One of his talks at this year's conference was on an
    education-focused project that he has been working on for around a year:
    a version of Python called "Snek" targeting embedded processors.
    He gave a look at some of the
    history of his work with 10-12 year-old students that led to the
    development of Snek as well as some plans for the language—and hardware to
    run it on—moving forward.
