Kernel prepatch 3.18-rc6

11 hours 7 min ago
The 3.18-rc6 prepatch is out, right on schedule. Linus says: "Steady progress towards final release, although we still have a big unknown worry in a regression that Dave Jones reported and that we haven't solved yet. In the process of chasing that one down, there's been a fair amount of looking at various low-level details, and that found some dubious issues, but no smoking gun yet."

Introducing AcousticBrainz

Friday 21st of November 2014 10:09:54 PM

MusicBrainz, the not-for-profit project that maintains an assortment of "open content" music metadata databases, has announced a new effort named AcousticBrainz. AcousticBrainz is designed to be an open, crowd-sourced database cataloging various "audio features" of music, including "low-level spectral information such as tempo, and additional high level descriptors for genres, moods, keys, scales and much more." The data collected is more comprehensive than MusicBrainz's existing AcoustID database, which deals only with acoustic fingerprinting for song recognition. The new project is a partnership with the Music Technology Group at Universitat Pompeu Fabra, and uses that group's free-software toolkit Essentia to perform its acoustic analyses. A follow-up post digs into the AcousticBrainz analysis of the project's initial 650,000-track data set, including examinations of genre, mood, key, and other factors.

A Friday kernel collection

Friday 21st of November 2014 09:05:48 PM

Greg Kroah-Hartman has released three new stable kernels: 3.10.61, 3.14.25, and 3.17.4, each containing important updates and fixes.

Version 2 of the kdbus patches posted

Friday 21st of November 2014 06:22:09 PM
The second version of the kdbus patches have been posted to the Linux kernel mailing list by Greg Kroah-Hartman. The biggest change since the original patch set (which we looked at in early November) is that kdbus now provides a filesystem-based interface (kdbusfs) rather than the /dev/kdbus device-based interface. There are lots of other changes in response to v1 review comments as well. "kdbus is a kernel-level IPC implementation that aims for resemblance to [the] protocol layer with the existing userspace D-Bus daemon while enabling some features that couldn't be implemented before in userspace."

McKenney: Stupid RCU Tricks: rcutorture Catches an RCU Bug

Thursday 20th of November 2014 09:30:34 PM
On his blog, Paul McKenney investigates a bug in read-copy update (RCU) in preparation for the 3.19 merge window. "Of course, we all have specific patches that we are suspicious of. So my next step was to revert suspect patches and to otherwise attempt to outguess the bug. Unfortunately, I quickly learned that the bug is difficult to reproduce, requiring something like 100 hours of focused rcutorture testing. Bisection based on 100-hour tests would have consumed the remainder of 2014 and a significant fraction of 2015, so something better was required. In fact, something way better was required because there was only a very small number of failures, which meant that the expected test time to reproduce the bug might well have been 200 hours or even 300 hours instead of my best guess of 100 hours."

Mozilla drops Google in favor of a multiple-search-partner plan

Thursday 20th of November 2014 12:32:19 AM

Mozilla has announced that it is not renewing the longstanding arrangement with Google that made Google the default search engine in Firefox in exchange for a sizable payment. Instead, when the current deal ends, Firefox will adopt different default search engines in different regions, a move described as a "more local and flexible approach to increase choice and innovation on the Web." Yahoo will be the default search engine in the United States, Yandex in Russia, and Baidu in China.

Mozilla CEO Chris Beard frames this change in terms of Mozilla's independence and non-commercial status. "This is why our independence matters. Being non-profit lets us make different choices. Choices that keep the Web open, everywhere and independent." The Yahoo deal, at least, lasts for five years, and one of the conditions was that Yahoo will support Mozilla's Do Not Track header. Google will remain a pre-installed search engine option, and will continue to provide Firefox's Safe Browsing and Geolocation features.

Today's Debian technical committee resignation: Ian Jackson

Wednesday 19th of November 2014 01:34:19 PM
Ian Jackson has announced his immediate resignation from the Debian technical committee. "While it is important that the views of the 30-40% of the project who agree with me should continue to be represented on the TC, I myself am clearly too controversial a figure at this point to do so. I should step aside to try to reduce the extent to which conversations about the project's governance are personalised. And, speaking personally, I am exhausted." (Thanks to Mattias Mattsson).

EFF: Let's Encrypt

Tuesday 18th of November 2014 10:15:09 PM
The Electronic Frontier Foundation (EFF) is helping to launch a new non-profit organization that will offer free server certificates beginning in summer 2015. "Let's Encrypt is a new free certificate authority, which will begin issuing server certificates in 2015. Server certificates are the anchor for any website that wants to offer HTTPS and encrypted traffic, proving that the server you are talking to is the server you intended to talk to. But these certificates have historically been expensive, as well as tricky to install and bothersome to update. The Let's Encrypt authority will offer server certificates at zero cost, supported by sophisticated new security protocols. The certificates will have automatic enrollment and renewal, and there will be publicly available records of all certificate issuance and revocation." Let's Encrypt will be overseen by the Internet Security Research Group (ISRG), a California public benefit corporation.

Live kernel patching for SUSE Enterprise Linux

Tuesday 18th of November 2014 02:27:14 PM
SUSE has announced that it is now using kGraft to make live kernel patches available for its enterprise distribution. "Unlike some other Linux kernel live patching technologies, SUSE Linux Enterprise Live Patching doesn't require stopping the whole system while it performs the patching. And because it is a fully open source solution, it allows for easy code review of the patch sources. SUSE is engaging with the upstream community to help ensure a sustainable future for kernel live patching on Linux in general and SUSE Linux Enterprise specifically."

Linux for lettuce (

Monday 17th of November 2014 09:26:24 PM covers the founding of the Open Source Seed Initiative (OSSI) and its continuing efforts to apply the concepts of open-source to plant breeding, in an increasingly patent encumbered space. "OSSI’s de facto leader is Jack Kloppenburg, a social scientist at the University of Wisconsin who has been involved with issues concerning plant genetic resources since the 1980s. He has published widely about the concept behind OSSI, and his words are now echoed (even copied verbatim) by public plant-breeding advocates in Germany, France, and India. As he explains it, for most of human history, seeds have naturally been part of the commons—those natural resources that are inherently public, like air or sunshine. But with the advent of plant-related intellectual property and the ownership it enables, this particular part of the commons has become a resource to be mined for private gain. Thus the need for a protected commons—open source seed. Inspired by open source software, OSSI’s idea is to use “the master’s tools” of intellectual property, but in ways the master never intended: to create and enforce an ethic of sharing."

Colin Watson resigns from Debian Technical Committee

Monday 17th of November 2014 05:44:49 PM
Colin Watson announced his resignation from the Debian Technical Committee before Russ. "I appreciate that the timing is such that this looks like a response to Joey's mails, or perhaps to some other recent discussions. That isn't the case. I've been doing a good deal of refactoring of my life recently as a result of realising that I was burning out, and right now it's important that I make an effort to spend my Debian time on things I find relaxing rather than things I've been finding stressful." (Thanks to Jeff Schroeder)
