An updated FSF high-priority project list

Tuesday 17th of January 2017 09:10:37 PM
The Free Software Foundation has reworked its high-priority project list to reflect its view of computing in 2017. See the changelog for a list of the changes that were made. Among other things, the Gnash flash player has fallen off the list. "Smart phones are the most widely used form of personal computer today. Thus, the need for a fully free phone operating system is crucial to the proliferation of software freedom."

[$] The Machine: Controlling storage with a filesystem

Tuesday 17th of January 2017 01:58:23 AM
Keith Packard is the chief architect for The Machine project at HPE; we covered his talk on this project back in 2015. At the 2017 linux.conf.au Kernel Miniconf, Packard focused on one specific aspect of The Machine's hardware and software configuration: how storage is managed and presented to applications. Like much that is being done with this project, its storage architecture is an interesting combination of new ideas and long-established techniques.

Calligra 3.0 released

Monday 16th of January 2017 10:00:18 PM
Calligra 3.0 has been released. The Calligra Suite includes office, graphics, and project management applications. "We have chosen to cut back on the number of applications. Krita has left us to be independent and although it was emotional it was also done with complete support from both sides. We are saying goodbye to Author, which never differentiated itself from Words. We also removed Brainstorm the purpose of which will be better fitted by a new application (nothing planned from our side). Flow and Stage has gone in this release but we intend to bring them back in the future." The 3.x series updates the applications to use KDE Frameworks 5 and Qt5.

Google Infrastructure Security Design Overview

Saturday 14th of January 2017 03:46:22 PM
Google has posted an overview of its infrastructure security. It includes information about low-level details, such as physical security and secure boot, encryption of data at rest as well as communications between services and to users, keeping employee devices and credentials safe, and more. Undoubtedly there are lessons here for many different organizations. "This document gives an overview of how security is designed into Google’s technical infrastructure. This global scale infrastructure is designed to provide security through the entire information processing lifecycle at Google. This infrastructure provides secure deployment of services, secure storage of data with end user privacy safeguards, secure communications between services, secure and private communication with customers over the internet, and safe operation by administrators. Google uses this infrastructure to build its internet services, including both consumer services such as Search, Gmail, and Photos, and enterprise services such as G Suite and Google Cloud Platform."

Quantum Computing Is Real, and D-Wave Just Open-Sourced It (Wired)

Friday 13th of January 2017 09:12:45 PM
Wired covers the release of Qbsolv as open-source software (under the Apache License v2) by D-Wave, which is a company that makes quantum computing hardware. Qbsolv is "designed to help developers program D-Wave machines without needing a background in quantum physics". Further: Qbsolv joins a small but growing pool of tools for would-be quantum computer programmers. Last year Scott Pakin of Los Alamos National Laboratory–and one of Qbsolv’s first users–released another free tool called Qmasm, which also eases the burden of writing code for D-Wave machines by freeing developers from having to worry about addressing the underlying hardware. The goal, Ewald says, is to kickstart a quantum computing software tools ecosystem and foster a community of developers working on quantum computing problems. In recent years, open source software has been the best way to build communities of both independent developers and big corporate contributors.

Of course to actually run the software you create with these tools, you’ll need access to one of the very few existing D-Wave machines. In the meantime, you can download a D-Wave simulator that will let you test the software on your own computer. Obviously this won’t be the same as running it on a piece of hardware that uses real quantum particles, but it’s a start.

Masnick: Techdirt's First Amendment Fight For Its Life

Thursday 12th of January 2017 10:45:35 PM
Over at Techdirt, Mike Masnick writes about a libel suit filed against the site: "As you may have heard, last week we were sued for $15 million by Shiva Ayyadurai, who claims to have invented email. We have written, at great length, about his claims and our opinion — backed up by detailed and thorough evidence — that email existed long before Ayyadurai created any software. We believe the legal claims in the lawsuit are meritless, and we intend to fight them and to win. There is a larger point here. Defamation claims like this can force independent media companies to capitulate and shut down due to mounting legal costs. Ayyadurai's attorney, Charles Harder, has already shown that this model can lead to exactly that result. His efforts helped put a much larger and much more well-resourced company than Techdirt completely out of business."

CVE-2016-9587: an unpleasant Ansible vulnerability

Wednesday 11th of January 2017 11:03:32 PM
The Ansible project is currently posting release candidates for the 2.1.4 and 2.2.1 releases. They fix an important security bug: "CVE-2016-9587 is rated as HIGH in risk, as a compromised remote system being managed via Ansible can lead to commands being run on the Ansible controller (as the user running the ansible or ansible-playbook command)." Until this release is made, it would make sense to be especially careful about running Ansible against systems that might have been compromised.

Update: see this advisory for much more detailed information.

[$] Python 2.8?

Wednesday 11th of January 2017 06:11:07 PM

The appearance of a "Python 2.8" got the attention of the Python core developers in early December. It is based on Python 2.7, with features backported from Python 3.x. In general, there was little support for the effort—core developers tend to clearly see Python 3 as the way forward—but no opposition to it either. The Python license makes it clear that these kinds of efforts are legal and even encouraged—any real opposition to the project lies in its name.

Kadlec: The MongoDB hack and the importance of secure defaults

Wednesday 11th of January 2017 05:09:53 PM
Tim Kadlec looks at the ongoing MongoDB compromises and how they came to be. "Before version 2.6.0, that wasn’t true. By default, MongoDB was left open to remote connections. Authentication is also not required by default, which means that out of the box installs of MongoDB before version 2.6.0 happily accept unauthenticated remote connections."

10 reasons to use Cinnamon as your Linux desktop environment

Recently I installed Fedora 25, and found that the current version of KDE Plasma was unstable for me; it crashed several times a day before I decided to try to try something different. After installing a number of alternative desktops and trying them all for a couple hours each, I finally settled on using Cinnamon until Plasma is patched and stable. Here's what I found. Read more

OpenSUSE and Fedora Elections

  • Michal Hrušecký: Running for re-election
    As you might have noticed, I’m running for re-election. I served my first term as openSUSE Board member, learned a lot and I think I could represent you well for another two years. Although this years elections will be tough as we have in the end quite some strong candidates. So honestly, I have no worries regarding result of the elections as it can’t end badly. Compare it to real world politics and elections where the results can be either bad or even worse… But even though our elections are quite friendly, it is still competition. So what would I do if I get elected? Why should you vote for me? I’ll try to answer it in this post.
  • Elections Retrospective, January 2017
    The results are in! The Fedora Elections for the Fedora 25 release cycle of FESCo, FAmSCo and the Council concluded on Tuesday, January 17th. The results are posted on the Fedora Voting Application and announced on the mailing lists. You can also find the full list of winning candidates below. I would also like to share some interesting statistics in this January 2017 Elections Retrospective.
