    Tschumperlé: My latest ten months working on G’MIC
    David Tschumperlé has posted an
    extensive summary of his work on G'MIC    , an image-processing tool.
    One of those projects was comic colorization:
    "The idea is very simple: Instead of forcing the artist to do all the
    colorization job by himself, we just ask him to put some colored key-points
    here and here, inside the different image regions to fill-in. Then, the
    algorithm tries to guess a probable colorization of the drawing, by
    analyzing the contours in the image and by interpolating the given colored
    key-points with respect to these contours.    " (LWN looked at G'MIC in August 2014).

    The Puppet design philosophy (O'Reilly)
    O'Reilly has posted an
    excerpt from Puppet Best Practices    , an upcoming book about the
    Puppet system configuration tool. It's a good place to look for those
    wanting an introduction to how Puppet works. "Puppet can be somewhat
    alien to technologists who have a background in automation scripting. Where
    most of our scripts scripts are procedural, Puppet is declarative. While a
    declarative language has many major advantages for configuration
    management, it does impose some interesting restrictions on the approaches
    we use to solve common problems.    "

    Announcing the release of Fedora 22 Beta
    Fedora 22 Beta has been released. It comes in Workstation, Server, and

    latest versions of rpm-ostree and rpm-ostree-toolbox and introduces the
    Atomic command line tool. The Server edition features a new database server
    role based on PostgreSQL, an updated Cockpit, and XFS as the default

    transitional Wayland support, and much more.

    How Tor is building a new Dark Net with help from the U.S. military (The Daily Dot)
    The Daily Dot reports
    that the Tor project is receiving some funding from the US Defense Advanced
    Research Projects Agency (DARPA) to improve Tor's hidden services. "The Dark Net road map moving forward is ambitious. Tor plans to double the encryption strength of hidden service’s identity key and to allow offline storage for that key, a major security upgrade.

    Next-generation hidden services may be run from multiple hosts to better deal with denial of service attacks and high traffic in general, a potentially big power boost that further closes the gap between the Dark Net and normal websites.    "
