    Poettering: systemd for Administrators, Part XVIII (controllers)
    The eighteenth installment of Lennart Poettering's "systemd for Administrators" series covers an interesting newish feature: integrated support for control group resource controllers. "When thinking about service management for systemd, we quickly realized that resource management must be core functionality of it. In a modern world -- regardless if server or embedded -- controlling CPU, Memory, and IO resources of the various services cannot be an afterthought, but must be built-in as first-class service settings. And it must be per-service and not per-process as the traditional nice values or POSIX Resource Limits were."

    Followers of the series may also want to take a peek at Part XVII, covering management of the journal.

    Raspberry Pi VideoCore driver code released
    The Raspberry Pi Foundation has announced that the
    source code for its video driver is now available under the BSD license.
    "If you’re not familiar with the status of open source drivers on ARM
    SoCs this announcement may not seem like such a big deal, but it does
    actually mean that the BCM2835 used in the Raspberry Pi is the first
    ARM-based multimedia SoC with fully-functional, vendor-provided (as opposed
    to partial, reverse engineered) fully open-source drivers, and that
    Broadcom is the first vendor to open their mobile GPU drivers up in this
    way.    "

    Ext4 data corruption trouble
    Stable kernel updates are supposed to be just that — stable. But they are
    not immune to bugs, as a recent ext4 filesystem problem has shown. In
    short: ext4 users would be well advised to avoid versions 3.4.14, 3.4.15,
    3.5.7, 3.6.2, and 3.6.3; they all contain a patch which can, in some
    situations, cause filesystem corruption.

    [$] The 2012 realtime minisummit
    As is generally the case when realtime Linux developers get together, the
    discussion soon turns to how (and when) to get the remaining pieces of the
    realtime patch set into the mainline. That was definitely the case at the 2012
    realtime minisummit, which was held October 18 in conjunction with the 14th Real Time
    Linux Workshop     (RTLWS) in Chapel Hill, North Carolina. Some other
    topics were
    addressed as well, of course, and a lively discussion ensued. Click below
    (subscribers only) for LWN's full report from the event.
