Real-world use of Linux multipath TCP

9 hours 2 sec ago
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."

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 (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."

KDE and Akademy

  • KDE Has Created Shashlik, A Way To Install Android Apps On Linux
    As you may know, KDE has created Shashlik, an emulator that permits the installation of Android apps on Linux systems. While Android is still Linux because they share the Linux kernel, Google’s OS has its own libraries and services while Linux uses the libraries and services brought by GNU.
  • Passing the Torch
    I hereby want to announce an open call to find a new maintainer for KDE’s speech recognition efforts.
  • Kubuntu Paddleboard Club
  • Akademy 2015 & Kate
    I didn’t do that much work on Kate, I mostly did small bugfixes for the applications bundled with the KDE Applications releases regarding their HiDPI support, finally no Konsole that can’t redraw correctly on scrolling on a HiDPI screen with scaling activated!
  • It’s the final countdown
  • Akademy 2015 coming to an end
    During the BoF days from Monday to Thursday, a great many tiny videos were shot of many of the attendees by Dan Leinir Turthra Jensen. These have been edited and cut up and turned into a video explaining, very shortly, what KDE really is. Being a community of people contributing to the development of software, the conclusion is straight forward. See the unsurprising conclusion in the video entitled What is KDE? (webm, mp4, vimeo), created as a tribute to the KDE community and all the amazing people in it.

  • Android for Work Gets Support from Major U.S. Carriers
    Earlier this year, we were reporting on one of the biggest security holes ever affecting Android. In fact, PaloAlto networks had found that that security breach affected almost 50 percent of Android devices, making them vulnerable to an attack that can swap out a user's pre-installed app with malware that can round up sensitive data. The fact is, concerns about security and other issues have made some enterprises wary of letting users standardize on Android devices.

    The OnePlus 2 will not become available in the U.S. and Europe until Aug. 11, but the first reviews of the Chinese startup's second flagship smartphone are already in, and the verdict is a resounding thumbs up from most people who were lucky enough to be given a preview build. When it comes to the OnePlus 2's design, reviewers agree that the device has a solid, comfortable build thanks to the textured sandstone panel on the back and the slight convex shape that curves right into the hands, while still evoking that premium feel with the aluminum frame holding up the device.
