  • Introducing dumb-init, an init system for Docker containers

    At Yelp we use Docker containers everywhere: we run tests in them, build tools around them, and even deploy them into production. In this post we introduce dumb-init, a simple init system written in C which we use inside our containers.

    Lightweight containers have made running a single process without normal init systems like systemd or sysvinit practical. However, omitting an init system often leads to incorrect handling of processes and signals, and can result in problems such as containers which can’t be gracefully stopped, or leaking containers which should have been destroyed.

  • Behind the scenes: How the FCC migrated to the cloud

    “We literally retired two Sun E25Ks, which as background, these systems each weigh one ton. We clearly did not want to load those into the trucks, and they were 11 years old. Those were moved to newer server blades that were lighter, more modular, etc., so that they could be more easily transported to the commercial data facility. Those one-ton systems could now be gracefully retired and disposed of as appropriate,” Bray said.

Leftovers: Software (Subsurface, GRUB, GIMP, and Todo.txt)

  • Announcing Subsurface 4.6.4
    The Subsurface development team proudly announces the release 4.6.4 of Subsurface, an open source dive log and dive planning program for Windows, Mac and Linux.
  • Subsurface 4.6.4 Open-Source Dive Log and Planning Tool Adds Many Improvements
    The development team behind the Subsurface open-source dive log and dive planning application was proud to announce the immediate availability for download of the Subsurface 4.6.4 release. Subsurface 4.6.4 is the latest stable version of the popular program developed by Linus Torvalds in collaboration with other developers, and adds a great number of improvements over previous builds. These include a new planner mode to calculate minimum gas, better handling of notes when replanning dives, as well as support for the border width setting in printing templates.
  • GRUB 2.02 Bootloader Officially Released with ZFS LZ4 & LVM RAID1 Support, More
    The long-anticipated GRUB 2.02 open-source bootloader software project was finally promoted to the stable channel after being in Beta stages of development for the past few years. The development team took their time to finalize the release of GRUB 2.02, which should soon make its way into the stable software repositories of your favorite operating system, but it's finally here and we want to thank them for all their hard work and the awesome new features and improvements implemented so far.
  • [New] GIMP review
    GIMP (short for GNU Image Manipulation Program) is a free alternative to Photoshop that more than holds its own. But don't think that the lack of a price tag means GIMP is lacking in features; it packs enough punch to genuinely rival Adobe's imaging behemoth. GIMP comes with impressive selection and montage features, various ways to retouch your images, cropping, noise reduction and colour adjustment tools, customisable brushes, gradients and so much more. There's plenty for the more advanced user, too, including layer masks, bezier curves, filters and even an animation package.
  • Todo.txt – A Nifty ToDo Indicator Applet for Ubuntu
    Todo.txt is an extremely simple indicator applet that lets you quickly tick off the tasks contained in your todo.txt file. It lives in the system tray and has options: Edit todo.txt, Clear completed, and refresh. Ultimately, its job is to help you edit your todo.txt file and mark tasks as completed without needing to open a full-fledged text editing application.
