Kernel prepatch 3.16-rc7

Sunday 27th of July 2014 10:42:43 PM
Linus has released 3.16-rc7. "We obviously *do* have various real fixes in here, but none of them look all that special or worrisome. And rc7 is finally noticeably smaller than previous rc's, so we clearly are calming down. So unlike my early worries, this might well be the last rc, we'll see how next week looks/feels."

The first stable CoreOS release

Friday 25th of July 2014 06:52:27 PM
The CoreOS developers have announced the release of version 367.1.0 of the CoreOS distribution; this is the first version deemed to be stable and ready for production. "Please note: The stable release is not including etcd and fleet as stable, this release is only targeted at the base OS and Docker 1.0. etcd/fleet stable support will be in subsequent releases." LWN looked at CoreOS last April.

Interview with Nathan Willis, GUADEC Keynote Speaker (GNOME News)

Friday 25th of July 2014 05:42:23 PM
LWN editor Nathan Willis is giving a keynote talk at the upcoming GUADEC (GNOME Users and Developers European Conference) and was interviewed by GNOME News. Willis's talk is titled "Should We Teach The Robot To Kill" and will look at free software and the automotive industry. "And, finally, my ultimate goal would be to persuade some people that the free-software community can — and should — take up the challenge and view the car as a first-rate environment where free software belongs. Because there will naturally be lots of little gaps where the different corporate projects don’t quite have every angle covered. But we don’t have to wait for other giant companies to come along and finish the job. We can get involved now, and if we do, then the next generation of automotive software will be stronger for it, both in terms of features and in terms of free-software ideals." GUADEC is being held in Strasbourg, France July 26–August 1.

Kügler: Plasma’s Road to Wayland

Friday 25th of July 2014 03:34:39 PM
On his blog, Sebastian Kügler looks at what's left to be done for KDE's Plasma desktop to support Wayland. He discusses why the project cares about Wayland, what it means to support Wayland, the current status, the strategy for further work, and how interested folks can get involved. "One of the important topics which we have (kind of) excluded from Plasma’s recent 5.0 release is support for Wayland. The reason is that much of the work that has gone into renovating our graphics stack was also needed in preparation for Wayland support in Plasma. In order to support Wayland systems properly, we needed to lift the software stack to Qt5, make X11 dependencies in our underlying libraries, Frameworks 5 optional. This part is pretty much done. We now need to ready support for non-X11 systems in our workspace components, the window manager and compositor, and the workspace shell."

Fedora 21 delayed three weeks

Thursday 24th of July 2014 11:25:42 PM
At yesterday's Fedora Engineering Steering Committee (FESCo) meeting, the release of Fedora 21 was delayed by three weeks (FESCo ticket), with the final release now scheduled for November 4. There are some problems with "test composes" of the release (creating test ISO images) that mean the deadline for the alpha release would be missed. The original plan was to delay for two weeks, but that put the freeze just before the Flock conference, so it was decided to push out an additional week.

An Interview with Karen Sandler (Model View Culture)

Thursday 24th of July 2014 06:19:46 PM
Over at Model View Culture, Adam Saunders interviews Karen Sandler, executive director of the Software Freedom Conservancy (SFC) and formerly the executive director of the GNOME Foundation. Sandler talks about SFC, the Outreach Program for Women, as well as being a cyborg: "I was diagnosed with a heart condition and needed a pacemaker/defibrillator, and none of the device manufacturers would let me see the source code that was to be literally sewn into my body and connected to my heart. My life relies on the proper functioning of software every day, and I have no confidence that it will. The FDA generally doesn't review the source code of medical devices nor can the public. But multiple researchers have shown that these devices can be maliciously hacked, with fatal consequences. Once you start considering medical devices, you quickly start to realize that it's all kinds of software that is life and society-critical - cars, voting machines, stock markets... It's essential that our software be safe, and the only way we can realistically expect that to be the case over time is by ensuring that our software is free and open. If there's catastrophic failure at Medtronic (the makers of my defibrillator), for example, I wouldn't be able to fix a bug in my own medical device."

[$] Browser tracking through "canvas fingerprinting"

Wednesday 23rd of July 2014 06:27:14 PM

Recently, public attention has been called to a new online user-tracking method that is purported to be nearly impossible to block. Called "canvas fingerprinting," the technique relies on forcing the browser to generate an image on the client side of the connection—an image that is unique enough to serve as a fingerprint for the browser that created it. In fact, the basis for this fingerprinting approach is several years old, but it does now seem to be in use in the wild. Whether or not it truly amounts to an insurmountable blocking challenge, however, remains to be seen.

Spencer: The Community Team

Tuesday 22nd of July 2014 07:44:39 PM
Rick Spencer introduces Ubuntu's community team. "First, we created the role Community Team Manager. Notice the important inclusion of the word “Team”. This person’s job is not to “manage the community”, but rather to organize and lead the rest of the community team members. This includes things like project planning, HR responsibilities, strategic planning and everything else entailed in being a good line manager. After a rather competitive interview process, with some strong candidates, one person clearly rose to the top as the best candidate. So, I would like formally introduce David Planella as the Community Team Manager!" Michael Hall, Daniel Holbach, and Nicholas Skaggs are the other members of the team.

Docker security with SELinux (Opensource.com)

Tuesday 22nd of July 2014 06:51:09 PM
Dan Walsh looks at container security, on Opensource.com. "I hear and read about a lot of people assuming that Docker containers actually sandbox applications—meaning they can run random applications on their system as root with Docker. They believe Docker containers will actually protect their host system [...] Stop assuming that Docker and the Linux kernel protect you from malware."

The EFF's open wireless router project

Monday 21st of July 2014 12:04:01 PM
The Electronic Frontier Foundation has announced a project to create a new distribution for wireless home routers. It is based on CeroWrt and is meant to make it easy and safe to run an open wireless network, include all of the latest bufferbloat fixes, and "advance the state of the art in consumer Wi-Fi router security and begin turning back the growing tide of attacks against them." The work is in an early state and only runs on Netgear WNDR3800 routers for now; testers and contributors are eagerly sought.

Kernel prepatch 3.16-rc6

Monday 21st of July 2014 11:55:00 AM
The 3.16-rc6 release is out, and Linus is starting to think that things are still too active. "Anyway, rc6 still isn't all *that* big, so I'm not exactly worried, but I am getting to the point where I'm going to start calling people names and shouting at you if you send me stuff that isn't appropriate for the late rc releases. Which is not to say that people did: while rc6 is bigger than I wished for, I don't think there's too much obviously frivolous in there. But I'll be keeping an eye out, and I'll be starting to get grumpy (or grumpiER) if I notice that people aren't being serious about trying to calm things down."
