  • EXT4 Patch For Statx Support

    The statx system call was added to Linux 4.11 for providing enhanced file stats. While the statx() system call is in place for Linux 4.11, not all of the file-systems yet support it.

  • TEE Subsystem Proposed For Linux 4.12 Kernel

    Linaro developers are hoping to merge the generic TEE subsystem into the Linux 4.12 kernel this spring.

    TEE is short for the Trusted Execution Environment and is a trusted OS running in a secure environment, such as TrustZone on ARM CPUs or a separate secure co-processor. We've previously covered the work on TEE for Linux and obviously not everyone is happy about "trusted" computing efforts on Linux and implementations like TEE.

  • Bcachefs Brings New On-Disk Format With Encryption, Better Multi-Device Support
  • Bcachefs - encryption, fsck, and more

    It's been far too long since the last announcement - lots of stuff has been
    happening. The biggest milestone has been all the breaking on disk format
    changes finally landing, but there's been lots of other stuff going on, too.

    On the subject of the breaking on disk format changes - there's an excellent
    chance this'll be the last breaking change, so if you're thinking about trying
    out bcachefs this is an excellent time. Also, if you have a filesystem in the
    old format, code to read your filesystem is available in the bcachefs-v0 braches
    of both linux-bcache and bcache-tools.

GNOME: Mutter, gresg, and GTK

  • Mutter 3.25.2 Has Bug Fixes, Some Performance Work
    Florian Müllner has pushed out an updated Mutter 3.25.2 window manager / compositor release in time for the GNOME 3.25.2 milestone in the road to this September's GNOME 3.26 release. Mutter 3.25.2 has a number of fixes ranging from fixing frame updates in certain scenarios, accessible screen coordinates on X11, some build issues, and more.
  • gresg – an XML resources generator
    For me, create GTK+ custom widgets is a very common task. Using templates for them, too.
  • Free Ideas for UI Frameworks, or How To Achieve Polished UI
    Ever since the original iPhone came out, I’ve had several ideas about how they managed to achieve such fluidity with relatively mediocre hardware. I mean, it was good at the time, but Android still struggles on hardware that makes that look like a 486… It’s absolutely my fault that none of these have been implemented in any open-source framework I’m aware of, so instead of sitting on these ideas and trotting them out at the pub every few months as we reminisce over what could have been, I’m writing about them here. I’m hoping that either someone takes them and runs with them, or that they get thoroughly debunked and I’m made to look like an idiot. The third option is of course that they’re ignored, which I think would be a shame, but given I’ve not managed to get the opportunity to implement them over the last decade, that would hardly be surprising. I feel I should clarify that these aren’t all my ideas, but include a mix of observation of and conjecture about contemporary software. This somewhat follows on from the post I made 6 years ago(!) So let’s begin.
