Real-world use of Linux multipath TCP

Saturday 1st of August 2015 01:56:15 PM
LWN looked at the Linux multipath TCP implementation back in 2013. That code remains out of tree, but it now seems that it is being used in some Samsung phones in Korea. "This service enables smartphone users to reach bandwidth of up to 1 Gbps on existing smartphones. This is probably the fastest commercially deployed mobile network. They achieve this high bandwidth by combining both fast LTE (with carrier aggregation) and fast WiFi networks on Multipath TCP enabled smartphones." (Thanks to Oliver Bonaventure).

OpenSSL: License Agreements and Changes Are Coming

Friday 31st of July 2015 10:10:29 PM

At the OpenSSL blog, Rich Salz has announced the project's decision to migrate away from the "rather unique and idiosyncratic" OpenSSL license to the Apache 2.0 license. In order to make the change in an upcoming release, though, the project "will soon require almost every contributor to have a signed a Contributor License Agreement (CLA) on file." Individual and corporate versions of the CLA are posted; trivial patches will evidently not trigger the need for the submitter to sign and file an agreement. Salz closes by noting that more details are still to come, since "there is a lot of grunt work needed to clean up the backlog and untangle all the years of work from the time when nobody paid much attention to this sort of detail."

Mozilla criticizes browser-selection change in Windows

Friday 31st of July 2015 09:50:20 PM

Mozilla has launched a multi-pronged campaign to challenge a recent change in Windows that has the effect of overriding users' choice of Firefox as the default web browser. Mozilla CEO Chris Beard posted a blog entry outlining the problem as well as an open letter to Microsoft CEO Satya Nadella. The change apparently landed with the recent Windows 10 release and, as Beard explains it, "while it is technically possible for people to preserve their previous settings and defaults, the design of the new Windows 10 upgrade experience and user interface does not make this obvious nor easy." Mozilla has also posted tutorials and videos to help users restore Firefox as their default browser.

A leadership change at FFmpeg

Friday 31st of July 2015 03:45:03 PM
FFmpeg leader Michael Niedermayer has announced his departure from the project. "I hope my resignation will make it easier for the teams to find back together and avoid a more complete split which would otherwise be the result sooner or later as the trees diverge and merging all improvements becomes too difficult for me to do."

Mourning Nóirín Plunkett

Thursday 30th of July 2015 08:53:12 AM
Here are a couple sad notes from the Ada Initiative and the Apache Software Foundation on the abrupt passing of Nóirín Plunkett.

Nóirín's passionate contributions and warm personality will be sorely missed. Many considered Nóirín a friend and viewed Nóirín's work to improving 'Women in Technology' as a great contribution to this cause."

[$] Building a Tizen IVI test experience

Wednesday 29th of July 2015 09:55:29 PM

In November of 2013, I decided to undertake a garage-hacking project and build an in-vehicle infotainment (IVI) Linux box for my own car. Motivated hobbyists have done such things for years, of course. But, after having followed the development of various automotive Linux projects (such as GENIVI and Tizen IVI), I wanted to put them to the test, rather than simply stuff a Raspberry Pi into the glove compartment and run Rhythmbox on a tiny screen on the dashboard. Interesting developments were happening at automakers and software vendors, and they were worth exploring. It turned out to be a rather large project, so to cover it fully will take more than one installment. The first major milestone involves understanding the unique hardware, power, and boot requirements of an IVI unit (as well as finding a distribution that fits the bill).

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

Tuesday 28th of July 2015 10:15:25 PM
Matt Thompson talks with Allen Gunn, Executive Director of Aspiration, at "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 (

Monday 27th of July 2015 09:37:37 PM 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."

Leftovers: Software

  • gtkmm now uses C++11
    All the *mm projects now require C++11. Current versions of g++ require you to use the –std=c++11 option for this, but the next version will probably use C++11 by default. We might have done this sooner if it had been clearer that g++ (and libstdc++) really really supported C++11 fully.
