  • Virtualization Management with SUSE Manager

    SUSE® Manager 4 is a best-in-class open source infrastructure management solution that lowers costs, enhances availability and reduces complexity for life-cycle management of Linux systems in large, complex and dynamic IT landscapes. You can use SUSE Manager to configure, deploy and administer thousands of Linux systems running on hypervisors, as containers, on bare metal systems, IoT devices and third-party cloud platforms. SUSE Manager also allows you to manage virtual machines (VMs).

    Virtualization is the means by which IT administrators create virtual resources, such as hardware platforms, storage devices, network resources and more. There are quite a few tools that enable the creation of virtual resources (such as Xen and KVM), but what about the management of those tools? That’s where SUSE Manager comes in.

  • Private and Air-Gap registry for openSUSE Kubic

    Sometimes there are occasions where direct internet access is not possible (proxy/offline/airgapped). Even in this setups it is possible to deploy and use Kubernetes with openSUSE Kubic and a local private registry.

    In this blog I will explain how to setup a local server which acts as private registry providing all the container images needed to deploy Kubernetes with openSUSE Kubic.

OnLogic Karbon 700: Passively-Cooled, Up To 8 Core / 16 Thread Industrial & Rugged PC

Filed under
Graphics/Benchmarks

OnLogic (formerly known as Logic Supply until a recent rebranding) announced the Karbon 700 back in August as a durable Linux-friendly computer largely intended for industrial applications but nothing prevents the user from using it as a passively, well-built desktop PC either. OnLogic recently sent over the Karbon 700 and it's been working out very well even with passively cooling an Intel Xeon eight-core / sixteen-thread processor, 16GB of RAM, 512GB NVMe storage, and more.

In suiting the Karbon 700 for industrial applications, this high-performance rugged computer supports power over Ethernet (PoE), wireless, the ability to have an external graphics card (though that variant is no longer fanless), CAN bus support, dual COM RS-232, 8-bit DIO, and other interfaces in addition to triple Gigabit LAN, triple DisplayPort, USB 3.1 Gen 1, and other connectivity options.

MSI Cubi 5 should make an excellent mini Linux computer

Filed under
Linux

If you want a basic Linux desktop, you can never go wrong with an all Intel-based mini computer -- such as that company's own NUC line. Things typically work without issue -- an Intel Wi-Fi card, for instance, shouldn't give you any headaches on Linux.

Intel is not the only game in town, however. Other companies manufacture and sell mini desktop computers too. Today, MSI unveils its latest, and it looks like a real winner. Called "Cubi 5," it comes with 10th gen Intel Comet Lake processors, USB-C, and supports Wi-Fi 6 (802.11ax).

"Keeping in mind the needs of consumers, MSI announces the world's first energy-efficient Mini-PC to be equipped with Intel’s 10th gen Comet Lake processors: Cubi 5. The Cubi 5 delivers upgraded computing capability as well as improved functionality. Cubi 5 may be small, but its performance can be improved all the way up to Intel Core i7 processor (Comet Lake), which helps deliver computing capability that will keep you in the flow, wherever you go," says MSI.

Boardcon has launched a “EM-IMX8M-MINI” SBC built around a “SOM-IMX8M-MINI” module that runs Linux on a quad -A53 i.MX8M Mini with 2GB LPDDR4, 8GB eMMC, and WiFi/BT. The SBC adds MIPI-DSI/CSI, GbE, USB, serial, CAN, and M.2.

Boardcon has produced a lot of Samsung and Rockchip based embedded boards, such as its recent, Rockchip RK3399 based CM3399 module and Idea3399 SBC, but the EM-IMX8M-MINI SBC and its SOM-IMX8M-MINI module are its first i.MX8 family boards. The i.MX8M Mini based EM-IMX8M-MINI, which like the Idea3399 is a sandwich-style, COM-and-carrier product, follows earlier NXP-based SBCs that we missed including the i.MX7-based EINK-IMX7 and i.MX6 UL powered EM6ul. We did cover its earlier i.MX287-based MINI287 module.

  • Woolen adventure game Woven is out today, some thoughts on my adventure

    A world stitched together with a clumsy stuffed animal for a protagonist, a flying mechanical bug companion and a softly spoken rhyming narrator, the adventure game Woven certainly has a lot of initial charm and it's out now.

    The developers said it's like "platform, point-and-click and action-adventure games without being exactly like any of them". To me though, it felt a lot simpler than that, more like a walking sim with basic puzzle elements.

  • Amusing action game Pirates, Vikings, and Knights II adds AI bot support

    The biggest problem for a lot of multiplayer games, even when they're free is pulling in players. To help with that, Pirates, Vikings, and Knights II now supports playing with AI bots.

    In the latest update released this month, it adds in bot support for when playing both offline and online. Now servers can fill up with bots and be replaced by players so you're not waiting around for anyone to join. There's also new achievements to do with the bots too, based on how many bot kills you get and one for if a bot manages to dominate you in the game.

  • Canonical enhances Kubernetes reliability for edge, IoT and multi-cloud

    14 November 2019: Canonical today announced high-availability clustering in MicroK8s, the workstation and appliance Kubernetes, and enterprise SQL database integration for its multi-cloud Charmed Kubernetes.

    “The rapid rise of enterprise and edge Kubernetes creates a challenge for corporate IT, with thousands of edge nodes running Kubernetes, and hundreds of cloud Kubernetes clusters,” said Stephan Fabel, Director of Product at Canonical. “The next generation of Canonical’s Kubernetes offerings reduce the number of moving parts, and embrace standard corporate SQL databases for Kubernetes data stores, to address the operational consequences of Kubernetes cluster sprawl.”

    Canonical’s MicroK8s gained popularity as an IoT, appliance and developer workstation Kubernetes, with a very small footprint suitable for edge devices and laptops. MicroK8s 1.16 added clustering, enabling rapid deployment of highly standardised small K8s clusters. The next step is to ensure high availability of these clusters, using Canonical’s Dqlite distributed SQL engine. Dqlite removes process overhead by embedding the database inside Kubernetes itself, and reduces the memory footprint of the cluster which is important for IoT.

    RAFT and SQLite are well-understood best practices for distributed and embedded systems. Using Dqlite as the Kubernetes datastore simplifies the deployment of a resilient K8s cluster. Telco and retail edge applications can now achieve high reliability at very low cost on x86 or ARM commodity appliances such as clusters of Intel NUCs or Raspberry Pi boards.

  • 2019 Add-ons Community Meetup in London

    At the end of October, the Firefox add-ons team hosted a day-long meetup with a group of privacy extension developers as part of the Mozilla Festival in London, UK. With 2019 drawing to a close, this meetup provided an excellent opportunity to hear feedback from developers involved in the Recommended Extensions program and to get input about some of our plans for 2020.

    [...]

    We recently announced that Firefox Preview, Mozilla’s next generation browser for Android built on GeckoView, will support extensions through the WebExtensions API. Members of the Android engineering team will build select APIs needed to initially support a small set of Recommended Extensions.

    The group discussed a wishlist of features for extensions on Android, including support for page actions and browser actions, history search, and the ability to manipulate context menus. These suggestions will be considered as work on Firefox Preview moves forward.

  • Here’s why pop culture and passwords don’t mix

    Were they on a break or not?! For nearly a decade, Ross and Rachel’s on-screen relationship was a point of contention for millions of viewers around the world. It’s no surprise to learn that years after the series finale, they are not only TV’s most beloved characters, but their names are popular account passwords, too. That’s right. More than thousands of internet users love Rachel, Monica, Joey, Chandler, Ross and Phoebe enough to use their names as passwords.

    Wondering about trends, we turned to haveibeenpwned (HIBP) — the website that aggregates data from known breaches — for pop culture favorites. (Firefox Monitor draws from HIBP to help people learn if they’ve been caught up in a data breach and take steps to protect themselves.)

    We couldn’t access any data files, browse lists of passwords or link passwords to logins — that info is inaccessible and kept secure — but we could look up random bad passwords manually on HIBP. It turns out, quite a lot of sitcom and sports fans are using pop culture passwords for their accounts. These bad passwords are not only weak, they have also been breached. Here’s what we spotted.

    Based on Chromium 78, the Opera 65 web browser is here and it's better than ever, brining a much-improved tracker blocker that finally lets you see which trackers are tracking your digital footprint while you're surfing the Internet.

    Based on the EasyPrivacy Tracking Protection list, Opera's tracker blocker feature will now show you all the trackers following you and let you take action against them if you believe some aren't good for you.

    By default, the tracker blocker will automatically block known tracker scripts to speed up the loading of pages and keep your online activity private. In Opera 65, the built-in tracker blocker can be toggled on and off per site too.

  • Department of Defense Enlists Red Hat to Help Improve Squadron Operations and Flight Training

    Red Hat, Inc., the world's leading provider of open source solutions, today announced that the Department of Defense (DoD) worked with Red Hat to help improve aircraft and pilot scheduling for United States Marine Corps (USMC), United States Navy (USN) and United States Air Force (USAF) aircrews. Using modern development practices and processes from Red Hat Open Innovation Labs that prioritized end user needs, the project team identified unaddressed roadblocks and gained new skills to build the right solution, a digital "Puckboard" application, for their unique scheduling challenge.

    [...]

    The problem facing squadrons was seemingly straightforward: how to improve and digitize the management of flight training operations. The existing process was entirely manual, each representing pertinent information like a pilot’s name, associated with their training syllabus, location and time of flights. Simple at a glance, the number of cognitive variables contained within this undertaking made it stressful for the operator and difficult to scale across squadrons and bases.

    For more than a decade, various project teams within the DoD had tried to improve the system via custom built applications, aircraft scheduling software and hybrid solutions. None of these deployments withstood the test of time or could be replicated if the operator took a new role elsewhere. The Defense Innovation Unit (DIU), an organization tasked with accelerating commercial technologies into the military, took on this challenge.

  • It's RedHat, And Everyone Else

    As time passes, it appears that corporations are primarily considering one distribution when considering installing Linux, and that distro is clearly RedHat. That probably does not come as any major surprise, but it appears RedHat's dominance continues to get stronger. What use to be a landscape littered with a multitude of choices has nearly been rendered down to one. Wow! That didn't take long. The open source software dynamic seemed to be formed on the premise that users were never again going to be pigeon-holed into using one piece of software. Or, perhaps better stated, that was a byproduct of making the source code readily available. And, that is still true to this day. However, as a corporate citizen in today's business climate, one finds themselves with limited possibilities.

    It was a mere 20 years ago when the buzz of Linux was starting to hit its stride. Everywhere you looked, there was a different flavor of Linux. There were nearly too many to count. And, these were not just hobbyist distros. Instead, they were corporations rising like corn stalks all over the place. Sure, there were more dominant players, but one had the ability to analyze at least 10 different fully corporate supported distributions when making a decision. With that amount of possibilities, the environment was ripe for consolidation or elimination. And, we have all watched that take place. But, did we ever think we were going to find ourselves in the current predicament?

    The data that has been collected over the past five years paints a concerning picture. Even a mere five years ago, it seemed likely that at a minimum RedHat would always have Suse as a legitimate competitor. After all, those were the two distros that seemed to win the consolidation and elimination war. At least in the corporate space. As was widely reported during that time, RedHat had somewhere in the neighborhood of 70% marketshare. It was always the gorilla in the room. But, Suse was always looked upon as an eager and willing participant, no matter its stature, and tended to garner most of the remaining marketshare. That is the way it appeared for a length of time prior to this decline over the past few years.

  • Scale testing the Red Hat OpenStack Edge with OpenShift

    Red Hat Openstack offers an Edge computing architecture called Distributed Compute Nodes (DCN), which allows for many hundreds or thousands of Edge sites by deploying hundreds or thousands of compute nodes remotely, all interacting with a central control plane over a routed (L3) network. Distributed compute nodes allow compute node sites to be deployed closer to where they are used, and are generally deployed in greater numbers than would occur in a central datacenter.

    With all the advantages that this architecture brings, there are also several scale challenges due to the large number of compute nodes that are managed by the OpenStack controllers. A previous post details deploying, running and testing a large scale environment using Red Hat OpenStack Director on real hardware, but this post is about how we can simulate far greater scale and load on the OpenStack control plane for testing using containers running on OpenShift without needing nearly as much hardware.

    In order to prove the effectiveness of Red Hat's DCN architecture, we'd like to be able to get quantitative benchmarks on Red Hat Openstack's performance when many hundreds or thousands of compute nodes are deployed.
