Debian 6.0 to get long-term support

13 hours 57 min ago
The Debian project has announced that the security support period for the 6.0 ("squeeze") release has been extended by nearly two years; it now runs out in February 2016. At the end, squeeze will have received a full five years of security support. "squeeze-lts is only going to support i386 and amd64. If you're running a different architecture you need to upgrade to Debian 7 (wheezy). Also there are going to be a few packages which will not be supported in squeeze-lts (e.g. a few web-based applications which cannot be supported for five years). There will be a tool to detect such unsupported packages."

ISC releases BIND 10 1.2, renames it, and turns it over to community

Thu, 17/04/2014 - 8:10pm
Internet Systems Consortium, the non-profit behind the BIND DNS server, has released version 1.2 of BIND 10, which is the last release it will make of the "applications framework for Internet infrastructure, such as DNS". That completes ISC's development effort on BIND 10, so it has renamed the project to Bundy and turned it over to the community for updates and maintenance. "'BIND 10 is an excellent software system,' said Scott Mann, ISC's Vice President of Engineering, 'and a huge step forward in open-source infrastructure software. Unfortunately, we do not have the resources to continue development on both projects, and BIND 9 is much more widely used.' 'The BIND 10 software is open-source,' Scott added, 'so we are making it available for anyone who wants to continue its development. The source will be available from GitHub under the name Bundy, to mitigate the confusion between it and ISC's BIND 9 (a completely separate system). The name 'BIND' is associated with ISC; we have changed its name as a reminder that ISC is no longer involved with the project.'"

Ubuntu 14.04 LTS (Trusty Tahr) released

Thu, 17/04/2014 - 6:24pm
Ubuntu has announced the release of its latest long-term support distribution: Ubuntu 14.04 LTS (aka "Trusty Tahr"). The release notes have all the details. It comes in a multitude of configurations, for desktops, servers, the cloud, phones, and tablets; also in many flavors: Kubuntu, Edubuntu, Xubuntu, Lubuntu, Ubuntu GNOME, Ubuntu Kylin, and Ubuntu Studio. "Ubuntu 14.04 LTS is the first long-term support release with support for the new "arm64" architecture for 64-bit ARM systems, as well as the "ppc64el" architecture for little-endian 64-bit POWER systems. This release also includes several subtle but welcome improvements to Unity, AppArmor, and a host of other great software."

Plant Breeders Release First 'Open Source Seeds' (NPR)

Thu, 17/04/2014 - 6:16pm
NPR has a look at the cross-pollination of open source software and agriculture, resulting in the release of the first "Open Source Seeds". The new Open Source Seed Initiative was formed to put seeds, and, more importantly, their genetic material, into a protected commons, so they will be available in perpetuity. "At an event on the campus of the University of Wisconsin, Madison, backers of the new Open Source Seed Initiative will pass out 29 new varieties of 14 different crops, including carrots, kale, broccoli and quinoa. Anyone receiving the seeds must pledge not to restrict their use by means of patents, licenses or any other kind of intellectual property. In fact, any future plant that's derived from these open source seeds also has to remain freely available as well." (Thanks to Rich Brown.)

Schaller: Preparing the ground for the Fedora Workstation

Wed, 16/04/2014 - 2:52pm
Here is a long piece from Christian Schaller describing the planning for the upcoming Fedora Workstation product. "So when we are planning the Fedora Workstation we are not just looking at what features we can develop for individual libraries or applications like GTK+, Firefox or LibreOffice, but we are looking at what we want the system as a whole to look like. And maybe most important we try our hardest to look at things from a feature/usecase viewpoint first as opposed to a specific technology viewpoint."

[$] Avoiding memory-allocation deadlocks

Wed, 16/04/2014 - 11:31am
There is a saying that you need to spend money to make money, though this apparent paradox is easily resolved with a start-up loan and the discipline of balancing expenses against income. A similar logic applies to the management of memory in an operating system kernel such as Linux: sometimes you need to allocate memory to free memory. Here, too, discipline is needed, though the typical consequences of not being sufficiently careful is not bankruptcy but rather a deadlock. The history of how the Linux kernel developed its balance between saving and spending is interesting as a microcosm of how Linux development proceeds.

Mozilla's interim CEO: Chris Beard

Mon, 14/04/2014 - 7:14pm
Mitchell Baker has announced that Chris Beard has been appointed to the board of directors and will be serving as the interim CEO. "In this time of transition there is no better person to lead us. Chris has one of the clearest visions of how to take the Mozilla mission and turn it into programs and activities and product ideas that I have ever seen. In the early years at Mozilla he was responsible for leading the Mozilla product, marketing and innovation teams. More recently, Chris was our CMO, leading user, developer and community engagement activities globally, including the initial launches of Firefox on Android and Firefox OS at MWC. Chris is the right person to lead us through this time and he is a strong candidate for CEO."

Kernel prepatch 3.15-rc1

Mon, 14/04/2014 - 12:17am
Linus has released the 3.15-rc1 prepatch and closed the merge window for this development cycle. "In comparison to those large releases, 3.15-rc1 is just big in general. No single big thing, but just lots and lots of commits. Sure, it has a few big new staging drivers (rtl8723au in particular), but even when big, those aren't nearly the bulk of things. There's just a lot going on." In the end, 12,034 non-merge changesets were pulled into the mainline repository during the 3.15 merge window.

Python Software Foundation opens membership to the entire Python community

Sun, 13/04/2014 - 3:13pm
During an April 13 keynote at PyCon, Van Lindberg, chair of the Python Software Foundation (PSF) board, announced that PSF membership would now be open to the entire community. It had previously been a self-sustaining membership, with current members nominating new members, but that has now changed. Community members can sign up as PSF members by way of a "Become a Member" button at the bottom of the Python home page. Filling out a a form and agreeing to the Code of Conduct is all that is required to join. Instead of the roughly 200 members reported at PyCon 2013, he would like to see 30,000 or more PSF members by the end of 2014. This is part of an effort to diversify the PSF in much the same way that the Python community itself has diversified over the years, Lindberg said.
