Power of Unikernels and Linux Graphics

  • Unikraft: Unleashing the Power of Unikernels

     The team at NEC Laboratories Europe spent quite a bit of time over the last few years developing unikernels – specialized virtual machine images targeting specific applications. This technology is fascinating to us because of its fantastic performance benefits: tiny memory footprints (hundreds of KBs or a few MBs), boot times compared to those of processes or throughput in the range of 10-40 Gb/s, among many other attributes. Specific metrics can be found in these articles: “My VM is Lighter (and Safer) than your Container,” “Unikernels Everywhere: The Case for Elastic CDNs,” and “ClickOS and the Art of Network Function Virtualization.”

    The potential of unikernels is great (as you can see from the work above), but there hasn’t been a massive adoption of unikernels. Why? Development time.  For example, developing Minipython, a MicroPython unikernel, took the better part of three months to put together and test. ClickOS, a unikernel for NFV, was the result of a couple of years of work.

  • First Batch Of AMDGPU Changes For Linux 4.16: DC Multi-Display Sync, Vega Tuning

    Alex Deucher of AMD sent in today their first batch of feature updates for Radeon/AMDGPU/TTM feature code for DRM-Next, which has already been queued, and will in turn land next year with the Linux 4.16 kernel.

  • Samsung Improving Cairo's OpenGL ES 3.x Support, May Eye Vulkan In Future

    Back in September there were developers from Samsung's Open-Source Group adding initial OpenGL ES 3.0 support to Cairo. The GLESv3 upbringing in Cairo is still ongoing and not yet fully vetted, but Bryce Harrington of Samsung OSG has now blogged about this effort.

    While there is the initial support for creating an OpenGL ES 3.0 context with Cairo, as Bryce explains in his new blog post, the work on GLES 3.0 for Cairo isn't complete. Additional code is still to be written to leverage new GLES3 functionality and they originally started writing this code for their Tizen platform.

Mozilla Adware

  • Mozilla Angers Firefox Users After Force-Installing Mr. Robot Promo Add-On
    Mozilla took a bit of heat this week after the organization force-installed a Mr. Robot promotional add-on in some Firefox browsers. The add-on, called Looking Glass, was intended to promote the season 3 finale of Mr. Robot that aired on Wednesday, December 13, but the whole media stunt failed miserably.
  • Firefox is on a slippery slope
    This extension was sideloaded into browsers via the “experiments” feature. Not only are these experiments enabled by default, but updates have been known to re-enable it if you turn it off. The advertisement addon shows up like this on your addon page, and was added to Firefox stable. If I saw this before I knew what was going on, I would think my browser was compromised! Apparently it was a mistake that this showed up on the addon page, though - it was supposed to be silently sideloaded into your browser! There’s a ticket on Bugzilla (Firefox’s bug tracker) for discussing this experiment, but it’s locked down and no one outside of Mozilla can see it. There’s another ticket, filed by concerned users, which has since been disabled and had many comments removed, particularly the angry (but respectful) ones.

Review: Daphile 17.09

Daphile is a minimal Linux distribution which is designed to be run on a computer dedicated to playing music. Daphile can be run on headless machines and its media controls are managed through a web-based interface. Basically, Daphile is intended to be run on a computer we can stick in the corner of a room and use it as a media centre without worrying about managing software, tweaking settings or navigating desktop environments. Daphile can be run from a CD or USB thumb drive for maximum portability and does not need to be installed directly on a hard drive to work. Daphile reportedly has the ability to rip audio CDs, play audio files from a local drive or stream music across network shares (Samba, NFS, FTP and OpenSSH services are supported). This gives us a pretty good range of media sources for our music collection. Under the hood, Daphile has its roots in Gentoo, though the operating system is somewhat stripped down and we cannot use Gentoo's package management utilities. Daphile runs the Busybox userland tools and a light web server, and very little else. In fact, Daphile does not provide a login interface to allow us to tinker with the operating system. The operating system is dedicated entirely to the task of playing music and our sole access to the media controls are through its web interface. The distribution is available in 32-bit and 64-bit builds and the ISO file we download for Daphile is 195MB in size. While Daphile is capable of running entirely without a screen, when we do boot from Daphile's media the distribution displays the distribution's IP address, which it obtains over DHCP. We can connect to the IP address using any modern web browser which automatically gives us access to Daphile's media controls, there is no user authentication built into the web interface. Read more
