Securing the future of GnuPG

sze, 2014-12-17 19:40
The GnuPG project is seeking donations. "For a critical project of this size two experienced developers are required for proper operation. This requires gross revenues of 120000 Euro per year. Unfortunately there is currently only one underpaid full time developer who is barely able to keep up with the work; see this blog entry for some background." (Thanks to Paul Wise)

Harmer: Overview of Qt3D 2.0 – Part 1

k, 2014-12-16 20:08
Sean Harmer covers the revival of Qt3D, a 3D framework. "With OpenGL taking a much more prominent position in Qt 5’s graphical stack — OpenGL is the underpinning of Qt Quick 2’s rendering power — and with OpenGL becoming a much more common part of customer projects, KDAB decided that it would be good for us and for the Qt community at large if we took over maintainership and development of the Qt3D module. To this end, several KDAB engineers have been working hard to bring Qt3D back to life and moreover to make it competitive to other modern 3D frameworks. This article is the first in a series that will cover the capabilities, APIs, and implementation of Qt3D in detail."

The Open Source Initiative's 2014 annual report

k, 2014-12-16 18:26
The Open Source Initiative has posted its annual report for 2014 [PDF] describing its efforts to increase its relevance. "In that context, 2014 was a turning point for OSI. Our decision to hire a General Manager started to bear fruit both in the form of a growing membership and of heightened activity. We saw news from new Affiliates appearing daily, profiles of individual members inspiring us through the newsletter and both categories of members bringing forward new ideas like the curriculum for further education and the hosting of OpenHatch. We also saw more corporate sponsors than ever before generously offering funds to support our growth. That meant we had the resources both to promote open source and to challenge abuses of the term around the world."

Scalability Techniques for Practical Synchronization Primitives (ACM Queue)

h, 2014-12-15 14:02
Davidlohr Bueso gives an overview of kernel locking scalability techniques in this ACM Queue article. "There have recently been significant efforts to address lock-scaling issues in the Linux kernel on large high-end servers. Many of the problems and solutions apply to similar system software. This article applies general ideas and lessons learned to a wider systems context, in the hope that it can be helpful to people who are encountering similar scaling problems."

Chromium to start marking HTTP as insecure

szo, 2014-12-13 15:24
The Chromium development team has posted a plan to start actively marking web pages served with HTTP as not being secure. "We know that people do not generally perceive the absence of a warning sign... Yet the only situation in which web browsers are guaranteed not to warn users is precisely when there is no chance of security: when the origin is transported via HTTP."

Launching CollabMark Project to Hack Trademarks for Free Culture

szo, 2014-12-13 01:03

Stanford Law School's Center for Internet and Society (CIS) has announced a project named CollabMark designed to "provide information about how open source and free culture communities can use trademarks." Specifically, the project "seeks to offer some strategies to collaborative communities, including a Collaborative Mark Policy that they can adopt to protect their name and logo in an open way" until, the announcement says, "trademark law evolves to accommodate collaborative work."

Fairphone: Our approach to software and ongoing support for the first Fairphones

cs, 2014-12-11 19:42
Over at the Fairphone blog, Kees Jongenburger reflects on what went right—and wrong—for the software that went into the first version of the Fairphone, which is a project aimed at creating a mobile phone that is, well, more "fair". The project seeks to inject social values into the supply chain so that minerals come from conflict-free mining, for example, and that the workers are provided with a living wage. "Fairphone’s high-level ambition is to bring more fairness to software. To us, that means focusing on two key principles: transparency and longevity. We believe products should be long-lasting. The longer a phone lasts, the less waste it creates and the fewer resources it requires. Longevity plays a role in hardware choices; and at the software level, longevity means keeping the software up-to-date and secure after the product was sold. Openness ties directly into our ideas for longevity. We believe that our community should have access to the source code of our software to make improvements, add cool functionality, and extend usability. We believe that releasing the code as open source will prolong the life of the phone past its commercial life. For the first Fairphone, we pinpointed a number of (in retrospect, over-ambitious) goals that aligned with the ideas of transparency and longevity." We looked at Fairphone back in July 2013.

[$] Emacs and changing documentation formats

sze, 2014-12-10 23:52

The GNU Emacs project is debating the idea of changing the format in which its official documentation is written and maintained. Proposing the change is Eric S. Raymond, who argues that the Texinfo format currently used is archaic and constitutes a barrier to entry. His proposal has its supporters—including Richard Stallman—but plenty of other project members contend that whatever shortcomings the Emacs documentation may have, replacing Texinfo as Raymond suggests is not the fix.
