[$] The kdbuswreck

By corbet Few readers will have failed to notice by now that the attempted merging of
the kdbus interprocess communication system into the 4.1 kernel has failed
to go as well as its proponents would have liked. As of this writing, the
discussion continues and nothing has been merged. This article constitutes
an attempt to derive a bit of light from the massive amounts of heat that
have been generated so far, with a specific focus on the issue of metadata
and capabilities.

How Tor is building a new Dark Net with help from the U.S. military (The Daily Dot)

By ris 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.”

The Puppet design philosophy (O’Reilly)

By corbet 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.

Tschumperlé: My latest ten months working on G’MIC

By corbet 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).
