Roadies vs. rock stars: The art of open leadership (Opensource.com)

Tuesday 28th of July 2015 10:15:25 PM
Matt Thompson talks with Allen Gunn, Executive Director of Aspiration, at Opensource.com. "I think you lead with a very earnest form of humility. The best forms of open are lovingly subversive, in that they draw others to form their own conclusions about the benefit of open rather than beating them over the head with it."

The Dronecode Foundation aims to keep UAVs open (Opensource.com)

Monday 27th of July 2015 09:37:37 PM
Opensource.com follows up with the Dronecode Foundation, which was founded in October 2014. "In the past year, Dronecode's developer community has grown from 1,200 to more than 2000 contributors, with more than 12,000 commits in the codebase. The rate of development is rapid with 1,000 commits being reviewed a month, with well over 2 million lines of code across the various Dronecode projects. Developers from Qualcomm, Intel, Parrot, Yuneec and many others are actively engaged in the development of the Dronecode technology stack. As a result, updates, new releases and project milestones are in motion all the time. For example, in late May, the APM project released version 3.3 of its flight code, and the PX4 project reached a milestone with the first RC candidate for release 1.0."

The Android "Stagefright" vulnerability

Monday 27th of July 2015 07:48:23 PM
Here is an article on the "Threatpost" site about a set of remotely exploitable media-library vulnerabilities present on vast numbers of Android devices. "An attacker in possession of their target’s phone number could send an MMS or even a Google Hangouts message to an affected device that triggers the vulnerability before the victim has a chance to open the message. In some cases, the attack would delete the MMS in question, leaving behind only a notification that a message was sent."

The fourth 4.2 prepatch is out for testing. Linus says: "I really wish that things were calming down, but it hasn't happened quite yet. It's not like this is particularly big or scary, but it's also not at the stage where it's really starting to get quiet and the bugs are really small and esoteric."

GNUnet: IETF getting cold feet about P2P Names?

Friday 24th of July 2015 09:28:37 PM

The GNUnet blog has this story about recent resistance from the IETF toward the standardization of "special use" domain names (such as .onion or .gnu) "to reduce the likelihood of ICANN accidentally creating a conflicting gTLD assignment."

Despite the provisions made in RFC 6761, the article notes that "there are also a number of DNS-centric people with a totally lack of alacrity in the dnsop WG to continue to stall the process by repeating arguments that were exchanged dozens of times in hundreds of e-mails." Among those offering resistance, it reports, is Internet Architecture Board Chair Andrew Sullivan, who "says the IETF should not support special use domain names threatening the DNS business model."

OpenSUSE Leap 42.1 milestone 1 released

Friday 24th of July 2015 09:03:02 PM
The first development release of the upcoming openSUSE 42.1 distribution is now available. "Milestone is being used to avoid the term Alpha because the milestone is able to be deployed without the additional future items and subsystems that will become available when Leap is officially released." As reported in June, openSUSE 42.1 is a new version of the distribution based on the SUSE Linux Enterprise core.

Day: HIG updates

Thursday 23rd of July 2015 10:24:31 PM

At his blog, Allan Day announces the first major update to the GNOME Human Interface Guidelines since the first GNOME 3 version (released in 2014). Day notes that the GNOME 3 HIG is structured around design patterns, in the hopes that it can be updated regularly to reflect current practices. "These new guidelines are the direct result of design work that has happened in the past year. They attempt to distill everything we’ve learned through our own process of trial and error." Furthermore, "the HIG now links to the relevant GTK+ API reference documentation for each design component. This is nice for knowing which widget does what; and makes the design guidelines a more effective accompaniment to the toolkit."

[$] Django Girls one year later

Wednesday 22nd of July 2015 09:06:30 PM

Though it got a bit of a late start due to some registration woes, the first day of EuroPython 2015 began with an engaging and well-received keynote. It recounted the history of a project that got its start just a year ago when the first Django Girls workshop was held at EuroPython 2014 in Berlin. The two women who started the project, Ola Sitarska and Ola Sendecka, spoke about how the workshop to teach women about Python and the Django web framework all came together—and the amazing progress that has been made by the organization in its first year.

[$] Domesticating applications, OpenBSD style

Tuesday 21st of July 2015 08:54:11 PM
One of the many approaches to improving system security consists of reducing the attack surface of a given program by restricting the range of system calls available to it. If an application has no need for access to the network, say, then removing its ability to use the socket() system call should cause no loss in functionality while reducing the scope of the mischief that can be made should that application be compromised. In the Linux world, this kind of sandboxing can be done using a security module or the seccomp() system call. OpenBSD has lacked this capability so far, but it may soon gain it via a somewhat different approach than has been seen in Linux.
