Flatpak 1.0 has released which is a great milestone for the Linux Desktop. I was asked at GUADEC whether a release video could be in place. In response, I spontaneously arranged to produce a voice-over with Sam during the GUADEC Video Editing BoF. Since then, I have been storyboarding, animating and editing the project in Blender. The music and soundscape has been produced by Simon-Claudius who has done an amazing job. Britt edited the voice-over and has lended me a great load of rendering power (thanks Britt!).

Red Hat Enterprise Linux 7.6 Beta now available

Filed under
Red Hat

The hybrid cloud requires a consistent foundation and today, we are pleased to refine and innovate that foundation with the availability of Red Hat Enterprise Linux 7.6 beta. The latest update to Red Hat Enterprise Linux 7 is designed to deliver control, confidence, and freedom to demanding business environments, keeping pace with cloud-native innovation while supporting new and existing production operations across the many footprints of enterprise IT.

As Red Hat’s Paul Cormier states, the hybrid cloud is becoming a default technology choice. Enterprises want the best answers to meet their specific needs, regardless of whether that’s through the public cloud or on bare metal in their own datacenter. Red Hat Enterprise Linux provides an answer to a wide variety of IT challenges, providing a stable, enterprise-grade backbone across all of IT’s footprints - physical, virtual, private cloud, and public cloud. As the future of IT turns towards workloads running across heterogeneous environments, Red Hat Enterprise Linux has focused on evolving to meet these changing needs.

  • Kubernetes on Metal with OpenShift

    My first concert was in the mid-80s, when AC/DC came to the Providence Civic Center in Rhode Island, and it was glorious. Music fans who grew up in the 80s will fondly remember the birth of MTV, the emergence of the King of Pop and the heyday of rock-n-roll’s heavy metal gone mainstream era, when long hair and guitar riffs both flowed freely. So recently when Def Leppard joined Journey at Fenway Park in Boston for their 2018 joint tour, I knew I had to be there.

    Metal also dominated the datacenter in the 80s and 90s, as mainframes and minicomputers made way for bare-metal servers running enterprise applications on UNIX and, soon after, open source Linux operating systems powered by Red Hat. Just like heavy metal eventually made way for the angst-filled grunge rock era of the 90s, so too did application provisioning on bare metal make way for the era of virtualization driven by VMWare – with subsequent VM sprawl and costly ELAs creating much angst to this day for many IT organizations.

  • Security Technologies: Stack Smashing Protection (StackGuard)

    In our previous blog, we saw how arbitrary code execution resulting from stack-buffer overflows can be partly mitigated by marking segments of memory as non-executable, a technology known as Execshield. However stack-buffer overflow exploits can still effectively overwrite the function return address, which leads to several interesting exploitation techniques like ret2libc, ret2gets, and ret2plt. With all of these methods, the function return address is overwritten and attacker controlled code is executed when the program control transfers to overwritten address on the stack.

  • Keeping both of your OpenShift Container Platforms Highly Available with Keepalived and HAproxy

    Until Kubernetes Federation hits the prime time, a number of solutions have sprung up as stop gaps to address geographically dispersing multiple cluster endpoints: stretch clusters and multiple clusters across multiple datacenters. The following article discusses how to configure Keepalived for maximum uptime of HAproxy with multiple cluster endpoints. In the following documentation an HAproxy and Keepalived configuration will be discussed in detail to load balance to the cluster(s) endpoints.

    In a production environment a Global server load balancing (GSLB) or Global Traffic Manager (GTM) would be used to give a differing IP address based on the originating location of the request. This would help to ensure traffic from Virginia or New York would get the closest location to the originating request.

    A big part of the Red Hat Open Brand Project has been looking back at our past and examining our roots. It is important that we imbue the new symbol with as much shared meaning from our history and culture as possible. To represent ourselves, we have to understand our origins.

  • October 19th Options Now Available For Red Hat (RHT)
  • Decentralize common Fedora apps with Cjdns

    Are you worried about a few huge corporations controlling the web? Don’t like censorship on centralized social media sites like facebook and twitter? You need to decentralize! The internet was designed to be decentralized. Many common activities, from social media to email to voice calls, don’t actually require a centralized service.

    The basic requirement for any peer to peer application is that the peers be able to reach each other. This is impossible today for most people using IP4 behind NAT (as with most household routers). The IP4 address space was exhausted over a decade ago. Most people are in “IP4 NAT Jail.”

    Your device is assigned a private IP, and translated to the public IP by the router. Without port forwarding to a specific private IP, incoming TCP connections or UDP sessions can’t tell where to forward to, and are dropped. As a result, nothing can connect to your device. You must connect to various public servers to do anything. IP4 NAT Jail forces centralization.

Software
  • Release 1.0.0

    Flatpak 1.0 is the first version in a new stable release series. This
    new 1.x series is the successor to the 0.10.x series, which was first
    introduced in October 2017. 1.0 is the new standard Flatpak version,
    and distributions are recommended to update to it as soon as possible.

    The following release notes describe the major changes since
    0.10.0. For a complete overview of Flatpak, please see
    docs.flatpak.org.

  • Linux Application Sandboxing And Distribution Framework Flatpak Reaches Version 1.0 Stable

    Flatpak, the Linux application sandboxing and distribution framework, has reached version 1.0 stable. Compared to the previous stable series (0.10.x), the new version should have faster installation and updates, it allows marking applications as end-of-life, and it asks the user to confirm app permissions at install time, among other improvements.

    Flatpak is a software utility for software deployment, package management, and application virtualization for Linux. Applications built with Flatpak can run on almost any Linux distribution. Flatpak applications run in a sandbox environment in which the applications are isolated from the rest of the system, and require permission from the user to access the user's files or access hardware devices.

  • Flatpak Linux App Sandboxing Hits 1.0 Milestone After Three Years in Development

    The Flatpak Linux application sandboxing and distribution framework, formerly XDG-App, used for building and distributing conternized apps on Linux desktops, has hit today the 1.0 milestone.

    After being in development for more than three years, the widely-used Flatpak Linux application sandboxing and distribution framework has finally reached the 1.0 version, which means that it's mature enough to be deployed and used in production environments for distributing and running Linux apps.

    "Flatpak 1.0 is the first version in a new stable release series. This new 1.x series is the successor to the 0.10.x series, which was first introduced in October 2017. 1.0 is the new standard Flatpak version, and distributions are recommended to update to it as soon as possible," said developer Alexander Larsson.

  • Red Hat Advances Container Storage

    Red Hat has moved to make storage a standard element of a container platform with the release of version 3.1 of Red Hat OpenShift Container Storage (OCS), previously known as Red Hat Container Native Storage.

    Irshad Raihan, senior manager for product marketing for Red Hat Storage, says Red Hat decided to rebrand its container storage offering to better reflect its tight integration with the Red Hat OpenShift platform. In addition, the term “container native” continues to lose relevance given all the different flavors of container storage that now exist, adds Raihan.

    The latest version of the container storage software from Red Hat adds arbiter volume support to enable high availability with efficient storage utilization and better performance, enhanced storage monitoring and configuration via the Red Hat implementation of the Prometheus container monitoring framework, and block-backed persistent volumes (PVs) that can be applied to both general application workloads and Red Hat OpenShift Container Platform (OCP) infrastructure workloads. Support for PVs is especially critical because to in the case of Red Hat OCS organizations can deploy more than 1,000 PVs per cluster, which helps to reduce cluster sprawl within the IT environment, says Raihan.

Interviews

Lennart Jern is a Swedish-speaking Finn, who has been living in Umeå, Sweden, for about three years. He was born and raised in southern Finland where he obtained his master’s degree in applied mathematics. His time at university exposed Lennart’s true passion. “While at the university, I realized that computer science was really what I wanted to work with.” In order to follow his dream of working in computer science he moved to Sweden with his wife to pursue a master’s program in computer science. After a short while he had learned enough to land a job with a local startup. “I’m working with cloud/distributed systems, specifically with tools like kubernetes and OpenShift.”

Lennart’s first contact with Linux was in 2006. Some of the computers in his high school were running OpenSuse. He installed Ubuntu’s Hardy Heron in 2008 and has been using Linux ever since.

Getting the team together to revolutionize Linux audio

So anyone reading my blog posts would probably have picked up on my excitement for the PipeWire project, the effort to unify the world of Linux audio, add an equivalent video bit and provide multimedia handling capabilities to containerized applications. The video part as I have mentioned before was the critical first step and that is starting to look really good with the screen sharing functionality in GNOME shell already using PipeWire and equivalent PipeWire support being added to KDE by Jan Grulich. We have internal patches for both Firefox and Chrome(ium) which we are polishing up to propose them upstream, but we will in the meantime offer them as downstream patches in Fedora as soon as they are ready for primetime. Once those patches are deployed you should have any browser based desktop sharing software, like Google Hangouts, working fully under Wayland (and X). Read more

  • CLVK Is Piping OpenCL On Top Of Vulkan
    The concept has been talked about before and there has been some previous work in this direction while "CLVK" is a newly-established effort for getting OpenCL running on top of Vulkan drivers. The challenge of OpenCL on Vulkan might not be as big as it seems to an outside observer considering both modern OpenCL and Vulkan rely on the SPIR-V intermediate representation, etc. There is also a plethora of tooling catering both to these compute and graphics APIs like clspv, which this CLVK project happens to rely upon as its compiler.
  • Guerilla UX Testing, and Other Experiences From Akademy
    It’s about a month now since the end of Akademy 2018 and I’ve finally found the time to write up some of my impressions from my favorite event of every year, and to encourage all of you to embrace both your inner User Experience (UX) Researcher and your inner guerilla.
  • Akademy 2018: I was there! part 2
    As you may know, a little more than a month ago Akademy happened at the beautiful place of Vienna. On my first post, I told you about how I was freaking out before giving my talk about Atelier. So, to continue my history, on the following days of Akademy, Tomaz brought his printer from Munich so we could test Atelier and try to dig up what we need to do to improve it. [...] After that fix, Akademy was happening really fast for me. We had Atelier BoF, and as in my talk, I was amazed at all the people that have shown interest in the project and the willingness to help us. Tomaz and I received a few inputs, and we are working with Chris and Patrick on how to achieve them and the goals of this project. Sometimes I don’t believe that I was out there, far from my house and my boyfriend to konquer the world. However, since the internet era, we have all this amazing technology that can record people talking, I had my talk record and it’s alive on youtube. And yes, I still don’t have the courage to watch.
  • I want to talk to the (Font) Manager
    You like fonts, don’t you? Well, we all do. So what happens if you want to install a fresh new font in your Linux distribution, and that distribution happens to be running, say, a Gnome desktop environment? You will have probably noticed that the font management facility available in the system settings tool is rather limited. First, there’s the actual issue of how to handle fonts in the first place – Gnome Tweak Tool – and then, you only have the ability to select from the existing range of fonts, but not really install any new ones. At the moment, it would seem, your one option is to manually copy font files into either the system or home directory fonts folder. Well, there’s a better way. Meet GTK+ Font Manager. Manager, meet your new user.

  • Saying Something Suitable in September
    So far the folks in the Ubuntu Podcast Chatter group have seen bits and pieces stating that I have been fussing over a Mythbuntu installation. It has been rough. I have two aerials in place connected to HDHomeRun Duo boxes. There is some reception of local stations. The problem with this is that I've had to put the antennae in the garage. When you understand that my part of northeast Ohio is essentially life in the deciduous forest, you'll also understand that the main Directv dish also is mounted on the garage as it had the only vantage point with a clear shot to the satellite(s). Eventually I will make further progress.

The text-based user interfaces will be maintained for those interested.
  • Chrome Now Logs all Google Users Into the Browser. Should You Care?
    I understand where Green is coming from, particularly after he clicked no for so long. But if this is the moment that Google leverages its browser in an unseemly way, I’m not seeing it. Sync isn’t enabled by default, meaning there’s not much of a change for users from a practical privacy standpoint. Green disagrees, because he’s seeing settings now that he didn’t have to think about before. But Google isn’t seeing any more or less of his data now than before, and won’t unless users opt in.

  • The future of Java and OpenJDK updates without Oracle support
    Oracle recently announced that it would no longer supply free (as in beer) binary downloads for JDK releases after a six-month period, and neither would Oracle engineers write patches for OpenJDK bugs after that period. This has caused a great deal of concern among some Java users. From my point of view, this is little more than business as usual. Several years ago, the OpenJDK 6 updates (jdk6u) project was relinquished by Oracle and I assumed leadership, and then the same happened with OpenJDK 7. Subsequently, Andrew Brygin of Azul took over the leadership of OpenJDK 6. The OpenJDK Vulnerability Group, with members from many organizations, collaborates on critical security issues. With the help of the wider OpenJDK community and my team at Red Hat, we have continued to provide updates for critical bugs and security vulnerabilities at regular intervals. I can see no reason why this process should not work in the same way for OpenJDK 8 and the next long-term support release, OpenJDK 11.

  • Istio on OpenShift: Technology Preview of Service Mesh Now Available
    We’re happy to announce the availability of our first technology preview of the Red Hat OpenShift Service Mesh, based on the Istio Project. The advancement of application/software development practices combined with technology/practice improvements in software delivery have resulted in a proliferation of application instances within many organizations. Whether these are macro/monoliths, “mini” services, or microservices, as the quantity of services increases, both the number and complexity of interactions increases. Until now much of the burden of managing these complex services interactions has been placed on the application developer. The evolution of sets of libraries like the Netflix Common Runtime Services & Libraries have brought many features and benefits for application resiliency, traffic control, etc. However, the use of these libraries is runtime-dependent (eg: Netflix’ libraries are Java-based) and they must be integrated into the application by the developer.
  • How open source game development hones valuable skills
    Two weeks ago I sat down with Michael Clayton and Jared Sprague to talk about Command Line Heroes: The Game. If you missed that post—have no fear—it is (of course) still available. But wait, why are we talking about games? In large part it’s because we’ve spent the last 12 months on the road asking people about their origin stories. And, after hundreds of interviews, we’ve come to understand that for many (but not all) their introduction to technology and/or computing started with video games. This inspired us to start Command Line Heroes season 2 with “Press Start,” an episode about how open source and video games share an origin story—one that takes place long before the terms “open source” and “internet” were even coined.
  • The Importance of a Nanosecond: Remembering Grace Hopper
    In the mid 1980s I was a young software engineer at Digital Equipment Corporation (DEC). Admiral Grace Hopper in those days worked for Digital as a consultant, mostly a goodwill ambassador. Similar to Red Hat's annual Summit conference, Digital ran an event called DECUS. And it was paired with an internal event called, imaginatively enough, Internal DECUS. Having spent two weeks installing and configuring every software product that Digital made onto a very overloaded VAX 11/730, I was hovering on the Internal DECUS show floor making sure the demos didn't crash.
