What Is the Intersection of OpenStack and Kubernetes?

Wed, 2018-06-20 18:37

Lew Tucker is a busy man. Aside from his day job as VP and CTO for Cloud Computing at Cisco, Tucker also sits on the board of directors at both the OpenStack Foundation and the Cloud Native Computing Foundation, giving him a unique perspective on both organizations.

Some in the industry have positioned Kubernetes as a competitive replacement for OpenStack, but that's not what Tucker sees. In a video interview, Tucker explains where the intersection currently exists between OpenStack and Kubernetes and why he expects both to be successful.

  • Vulkan Display Extensions To Be Used By SteamVR Merged Into Mesa RADV/ANV

    Keith Packard's long in development work for improving the Linux display stack infrastructure for better dealing with VR head-mounted displays is about rounded out with the new Vulkan extension support being merged into Mesa.

    Just over a year ago famed X developer Keith Packard started contract work for Valve to improve the plumbing around the Linux/X.Org support for virtual reality HMDs for better performance and better integration. Within the Linux kernel and the X.Org Server he's worked and landed the DRM leasing support of outputs to let a VR compositor (Steam VR) have direct access to the output, "non-desktop" quirk handling so VR HMDs don't become mapped as part of a standard Linux desktop, and related work.

  • A Slew Of AMDGPU DC Updates Published, Further Improvements For Raven Ridge

    There hasn't been a new AMDGPU DC code drop in a while as AMD developers work to improve their internal processes, but hitting the wire today is a set of 51 new patches for this "display code" stack that work on a variety of improvements.

  • Sway 1.0 Wayland Compositor Nears With Floating Windows, Tablet Support & More

    The release of the Sway 1.0 Wayland compositor is inching closer with the recent third alpha release. Sway for the uninformed is a very promising i3-compatible Wayland compositor.

    Earlier this month Sway 1.0 Alpha 3 was released to succeed the second alpha release from the month prior. Sway 1.0 is succeeding the Sway 0.15 changes with a great deal of improvements. Most notably with the 1.0 series is now requiring the WLROOTS modular Wayland compositor library.

Security: OpenBSD, FUD and More

Wed, 2018-06-20 17:36
  • OpenBSD Disabling SMT / Hyper Threading Due To Security Concerns

    Security oriented BSD operating system OpenBSD is making the move to disable Hyper Threading (HT) on Intel CPUs and more broadly moving to disable SMT (Simultanious Multi Threading) on other CPUs too.

    Disabling of Intel HT and to follow with disabling SMT for other architectures is being done in the name of security. "SMT (Simultanious Multi Threading) implementations typically share TLBs and L1 caches between threads. This can make cache timing attacks a lot easier and we strongly suspect that this will make several spectre-class bugs exploitable. Especially on Intel's SMT implementation which is better known as Hypter-threading. We really should not run different security domains on different processor threads of the same core."

    OpenBSD could improve their kernel's scheduler to workaround this, but given that is a large feat, at least for now they have decided to disable Hyper Threading by default.

    Those wishing to toggle the OpenBSD SMT support can use the new hw.smt sysctl setting on OpenBSD/AMD64 and is being extended to cover CPUs from other vendors and architectures.

  • Does Open Source Boost Security? Hortonworks Says Yes

    Organizations are best served security-wise if they favor and adopt open source technology — especially enterprise open source — over proprietary alternatives, according to Hortonworks. However, not everybody agrees that open source software intrinsically is more secure.

    It’s tough to argue that open source hasn’t brought significant benefits to the IT industry and the tens of thousands of organizations that rely on IT products to automate their operations. Starting with the introduction of Linux in the late 1990s, major swaths of the tech industry have shifted to open source development methodologies. That includes the vast majority of the big data ecosystem, which has been largely bootstrapped by various Apache Software Foundation projects.

  • Call for Feedback! Draft of Goal-Metrics for Diversity & Inclusion in Open Source (CHAOSS)

    In the last few months, Mozilla has invested in collaboration with other open source project leaders and academics who care about improving diversity & inclusion in Open Source through the CHAOSS D&I working group. Contributors so far include:

    Alexander Serebrenik (Eindhoven University of Technology) , Akshita Gupta (Outreachy), Amy Marrich (OpenStack), Anita Sarma (Oregon State University), Bhagashree Uday (Fedora), Daniel Izquierdo (Bitergia), Emma Irwin (Mozilla), Georg Link (University of Nebraska at Omaha), Gina Helfrich (NumFOCUS), Nicole Huesman (Intel) and Sean Goggins ((University of Missouri).

  • Introducing A-Terrain - a cartography component for A-Frame

    Have you ever wanted to make a small web app to share your favorite places with your friends? For example your favorite photographs attached to a hike, or just a view of your favorite peak, or your favorite places downtown, or a suggested itinerary for friends visiting?

  • Setting up Arcanist for Mozilla development on Windows
  • Taming Phabricator

    So Mozilla is going all-in on Phabricator and Differential as a code review tool. I have mixed feelings on this, not least because it’s support for patch series is more manual than I’d like. But since this is the choice Mozilla has made I might as well start to get used to it. One of the first things you see when you log into Phabricator is a default view full of information.

Canonical: GNOME Software, Buzzwords, Ubuntu Server, Themes and Zenkit

Wed, 2018-06-20 17:09
  • Report from the GNOME Software design sprint

    A couple of weeks ago representatives from across Canonical met in London to talk about ideas to improve the user experience of GNOME Software. We had people from the store team, snap advocacy, snapd, design and from the desktop team. We were also fortunate enough to be joined by Richard Hughes representing upstream GNOME Software.

  • Emerging Trends in Financial Services: IoT, AI and Blockchain

    The answer has its roots at both an infrastructure level, where legacy technology is being replaced with something more akin to what is seen in challengers banks or in technology leaders from Silicon Valley, and in changing mentalities, where a new mindset can be just as important as the technology that’s adopted.

    Of course, to say that this is simply a technological problem is naive, often, technology implementation is the easy part, with the larger challenge coming with organisational acceptance of the need to change.

    Often, the case is that an organisation isn’t culturally ready for change, resulting in projects that fail and negatively impact the ability to evolve with an increasingly tumultuous market that is being impacted by regulatory changes and a technology revolution.

    Mark Baker, Field Product Manager at Canonical, said: “We tend to find that the technology is the easy part once we’ve got the business aligned around a common goal with common sets of objectives and accepting of the change.”

    However, once an organisation is culturally aligned around a common goal and is accepting of technological change, then it is possible to work with a technology partner like Canonical in order to deploying the technology simple.

  • Ubuntu Server development summary – 19 June 2018

    The purpose of this communication is to provide a status update and highlights for any interesting subjects from the Ubuntu Server Team.

  • Simple Dark/Light GTK/Gnome Shell Theme for Ubuntu 18.04 LTS (Bionic Beaver)

    There are many dark themes for GTK with a simple and good color scheme. But, I have been looking for a simple dark theme especially for Ubuntu 18.04 LTS (Bionic Beaver). I tried many Dark themes on Ubuntu 18.04 LTS (Bionic Beaver) and my mind was set on Qogir Dark theme.

    The simple design and the comfort of the dark colors scheme is quite amazing and gives a relief looking for the desktop environment. Qogir comes with a Dark and Light Theme for GTK 2.0 / GTK 3.0 and Gnome Shell. The Dark or the Light theme integration with the default installed applications such as Nautilus file manager, LibreOffice and Mozilla Firefox are quite good.

  • Zenkit: The influence of developer communities in progressing snaps

    Last month, Zenkit published their project management tool as a snap. For those not familiar with Zenkit, they introduced themselves in a guest blog at the time the snap was published which can be read here. Since then, we caught up with Philipp Beck, Full Stack Developer at Zenkit, to discover his opinion on snaps and the publishing experience.

    Philipp was introduced to snaps via a developer friend of his and could immediately appreciate the potential benefits for Zenkit to pursue and the advantages it would offer their users. For the former, Philipp comments: “The biggest draw for us was the ease at which we could reach a diverse range of Linux users, without having to specifically package Zenkit for each distribution. There are obvious benefits here in terms of time saved in updating multiple Linux packages too.”

OpenSUSE Tumbleweed Updated

Wed, 2018-06-20 16:54
  • Tumbleweed Delivers New Kernel, Applications, Plasma, libvirt

    The past week brought a total of three openSUSE Tumbleweed snapshots and a bunch of new features and improvements for KDE users.

    Snapshot 20180618 updated just a few packages to include an updated GNU Compiler Collection 7, which fixes support for 32-bit AddressSanitizer with glibc 2.27+. Both perl-File-ShareDir and python-numpy were the other two packages that gave users minor fixes.

    The snapshots earlier in the week were more KDE centric. Snapshot 20180615 delivered KDE Applications 18.04.2. The updated applications focused on bugfixes, improvements and translations for Dolphin, Gwenview, KGpg, Kig, Konsole, Lokalize, Okular and many more. KGpg no longer fails to decrypt messages without a version header and image with Gwenview can now be redone after undoing them. The Linux Kernel jumped from 4.16.12 to 4.17.1 and fixed some btrfs and KVM issues. The newer kernel also ported an arm fix for HDMI output routing and fixed an atomic sequence handling with spi-nor and intel-spi. The hwinfo package tried a more aggressive way to catch all usb platform controllers with the 21.55 version. Libvirt 4.4.0 added support for migration of Virtual Machines with non-shared storage over Thread-Local Storage (TLS) and introduced a new virDomainDetachDevice Alias. Lenovo, HP and Dell tablets gaining greater support with the updated libwacom 0.30 package. Add support for PostgreSQL-style UPSERT were made available with sqlite3 3.24.0. Other tools like mercurial 4.6.1, snapper 0.5.5 were also updated in the snapshot.

  • OpenSUSE Tumbleweed Jumps On Linux 4.17, KDE Plasma 5.13 Riding Well

Google’s Fuchsia Adds Emulator for Running Linux Apps

Wed, 2018-06-20 16:32

Google has added a Guest app to its emergent and currently open source Fuchsia OS to enable Linux apps to run within Fuchsia as a virtual machine (VM). The Guest app makes use of a library called Machina that permits closer integration with the OS than is available with typical emulators, according to a recent 9to5Google story.

Last month, Google announced a Project Crostini technology that will soon let Chromebook users more easily run mainstream Linux applications within a Chrome OS VM. This week, Acer’s Chromebook Flip C101 joined the short list of Chromebooks that will offer Linux support later this year.

Latest Ubuntu Touch release from UBPorts is based on Ubuntu 16.04 LTS

Wed, 2018-06-20 08:56

Canonical may have stopped developing/supporting a version of Ubuntu for smartphones and tablets. But the folks at UBPorts have kept the idea of a touch-friendly version of Ubuntu alive for the past year.

Now the team has released Ubuntu Touch RC OTA-4, which is the first version based on Ubuntu 16.04 Xenial Xerus.

That’s significant because Xenial is an LTS (Long Term Support) release, which means the underlying operating system will still be supported by Canonical until 2021.

Debian GNU/Linux 10 "Buster" Installer Updated with Linux Kernel 4.16 Support

Wed, 2018-06-20 08:55

Developed under the Debian Testing umbrella, the forthcoming Debian GNU/Linux 10 "Buster" operating system series just received today the third alpha milestone of its installer, which lets people install the Linux-based operating system on their personal computers, servers, and IoT devices, such as the Raspberry Pi.

One of the most interesting changes that caught out eyes is the bump of the kernel support from Linux kernel 4.13, which was used in the second alpha build, to Linux kernel 4.16. Of course, this means that there's better hardware support, so chances are you'll be able to install the development version of Debian GNU/Linux 10 "Buster" on newer machines or if you have some exotic components on your PC.

First Ubuntu Touch OTA-4 Release Candidate Based on Ubuntu 16.04 LTS Is Here

Tue, 2018-06-19 22:10

The latest Ubuntu Touch update from UBports, OTA-3, was released last year near the Christmas holidays, but it was still based on Ubuntu 15.04 (Vivid Vervet), so if you though Ubuntu Phones are dead, think again, because the UBports team has been hard at work to bring you the OTA-4, which will be the first to rebase the operating system on Ubuntu 16.04 LTS (Xenial Xerus).

"The main reason why the arrival of OTA-4 seemed to take so long is because Ubuntu Touch switched its base to Ubuntu 16.04 LTS Xenial Xerus. This is a mammoth milestone for the project, because it allowed us to transition from the unsupported Ubuntu 15.04 Vivid Vervet to a Long Term Support (LTS) base," reads today's announcement.

  • A Session Suspension & Restoration Protocol Proposed For Wayland

    KDE Wayland developer Roman Gilg who started contributing to Wayland via last year's Google Summer of Code is proposing a new Wayland protocol for dealing with desktop session suspension and restoration.

    This protocol extension would allow for more efficient support for client session suspension and restoration such as when you are logging out of your desktop session and want the windows restored at next log-in or if you are suspending your system. While Roman Gilg is working on this protocol with his KDE hat on, he has been talking with Sway and GNOME developers too for ensuring this protocol could work out for their needs.
