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."

[$] The long road to getrandom() in glibc

Monday 9th of January 2017 10:33:57 PM
The GNU C library (glibc) 2.25 release is expected to be available at the beginning of February; among the new features in this release will be a wrapper for the Linux getrandom() system call. One might well wonder why getrandom() is only appearing in this release, given that kernel support arrived with the 3.17 release in 2014 and that the glibc project is supposed to be more receptive to new features these days. A look at the history of this particular change highlights some of the reasons why getting new features into glibc is still hard.

Kernel prepatch 4.10-rc3

Sunday 8th of January 2017 11:21:08 PM
The 4.10-rc3 kernel prepatch is available for testing. Linus says: "It still feels a bit smaller than a usual rc3, but for the first real rc after the merge window (ie I'd compare it to a regular rc2), it's fairly normal."

Vault CFP deadline approaching

Saturday 7th of January 2017 08:03:51 PM
The Vault Storage and Filesystems conference will be held March 22 and 23 in Cambridge, MA, USA, immediately after the Linux Storage, Filesystem, and Memory-Management Summit. The call for presentations expires on January 14, and the conference organizers would really like to get a few more proposals in before then. Developers interested in speaking at a technical Linux event are encourage to sign up.

(Also, don't forget the LWN CFP deadlines calendar, which is a good way to stay on top of conference proposal deadlines.)

My WATCH runs GNU/Linux And It Is Amazing (LearntEmail)

Friday 6th of January 2017 08:45:59 PM
The LearntEmail blog has a look at running AsteroidOS on the LG Watch Urbane smartwatch. "It looks like a watch, it smells like a watch, but it runs like a normal computer. Wayland, systemd, polkit, dbus and friends look very friendly to hacking. Even Qt is better than android, but that's debatable. My next project - run Gtk+ on the watch :)" (Thanks to Paul Wise.)

Linux 4.10-rc5

Things seem to be calming down a bit, and everything looks nominal. There's only been about 250 changes (not counting merges) in the last week, and the diffstat touches less than 300 files (with drivers and architecture updates being the bulk, but there's tooling, networking and filesystems in there too).

KDE Neon Installer

  • KDE Neon Has Stylish New Install Wizard
    KDE Neon has adopted distro-agnostic Linux installer ‘Calamares’ its unstable developer edition. Calamares replaces the Canonical-developed Ubiquity installer as the default graphical installer used when installing the Ubuntu-based OS on a new machine. The stylish install wizard is already in use on a number of other KDE-based Linux distributions, including Chakra Linux and Netrunner.
  • KDE neon Inaugurated with Calamares Installer
    You voted for change and today we’re bringing change. Today we give back the installer to the people. Today Calamares 3 was released. It’s been a long standing wish of KDE neon to switch to the Calamares installer. Calamares is a distro independent installer used by various projects such as Netrunner and Tanglu. It’s written in Qt and KDE Frameworks and has modules in C++ or Python.
