Red Hat
  • Fedora 29 Aims To Better Support FPGAs

    A rather late self-contained feature proposal for the in-development Fedora 29 is to better support FPGAs.

    Given the growing number of devices appearing with onboard FPGAs thanks to machine/deep learning, AI, and other workloads that can be accelerated on FPGAs, Fedora 29 is aiming to better support them. The support will be focused on FPGAs with good upstream kernel support and utilizing the FPGA manager framework that is vendor-neutral.

  • [Week 9] GSoC Status Report for Fedora App: Amitosh

    You can now subscribe to a particular calendar from the Fedora app!. No more missed meetings. We also take care of converting the date and time to the local timezone so that you get the reminders at the correct time.

    Subscribing to a calendar automatically syncs all events for a calendar on FedoCal to the device calendar. If the device calendar syncs with a sync provider such as Google calendar, you will get the notification in all synced devices. If a meeting is deleted or removed, the reminder will dismissed as well.

  • Flatpak – a look behind the portal

    There are several principles that have guided the design of the existing portals.

    Keep the user in control

    To achieve this, most portals will show a dialog to let the user accept or deny the applications’ request. This is not a hard rule — in some cases, a dialog is just not practical.

    Avoid yes/no questions

    Direct questions about permissions tend to be dismissed without much thought, since they get in the way of the task at hand. Therefore, portals avoid this kind of question whenever possible and instead just let the user get on with the task.

    For example, when an app is requesting to open a file on the host, we just present the user with a fille chooser. By selecting a file, the user implicitly grants the application access to the file. Or he can cancel the file selection and implicitly deny the applications’ request.

    Don’t be annoying

    Nothing is worse than having to answer the same question over and over. Portals make use of a database to record previous decisions and avoid asking repeatedly for the same thing.

    [...]

    If you want to explore how portals work, or just need to double-check which files an app has access to, flatpak has tools that let you do so conveniently.

An update from Fedora Workstation land

Filed under
Red Hat

Feral Interactive, one of the leading Linux game companies, released a tool they call gamemode for Linux not long ago. Since we want gamers to be first class citizens in Fedora Workstation we ended up going back and forth internally a bit about what to do about it, basically discussing if there was another way to resolve the problem even more seamlessly than gamemode. In the end we concluded that while the ideal solution would be to have the default CPU governor be able to deal with games better, we also realized that the technical challenge games posed to the CPU governor, by having a very uneven workload, is hard to resolve automatically and not something we have the resources currently to take a deep dive into. So in the end we decided that just packaging gamemode was the most reasonable way forward. So the package is lined up for the next batch update in Fedora 28 so you should soon be able to install it and for Fedora Workstation 29 we are looking at including it as part of the default install.

Red Hat and CentOS Fix Kernel Bug in Latest OS Versions, Urge Users to Update

Filed under
OS
Red Hat
Security

It would appear the there was a bug in the previous Linux kernel update for the Red Hat Enterprise Linux 7.5 and CentOS Linux 7.5 releases, which was released to address the Spectre V4 security vulnerability, making connection tracking information to not function correctly, which could lead to connectivity loss and leaking of configuration properties related to the respective connection tracking into other namespaces.

"Previously, the connection tracking information was not cleared properly for packets forwarded to another network namespace," said Red Hat in an advisory. "Packets that were marked with the "NOTRACK" target in one namespace were excluded from connection tracking even in the new namespace. Consequently, a loss of connectivity occasionally occurred, depending on the packet filtering ruleset of the other network namespaces."

RPM And Yum Are A Big Deal For IBM i. Here’s Why

Filed under
Red Hat
Server

By now you’ve probably heard about Yum and RPM, the new processes that IBM will use to deliver open source software to IBM i customers. But you may have questions about how the process works, and what the benefits will be. IT Jungle talked with IBM’s open source guru Jesse Gorzinski to get the low down on why the new tech is so important to the platform.

RPM, which stands for Red Hat Package Manager, is a piece of software created more than 20 years that allows customers in that Linux community to more easily distribute and install the various pieces of software required to create a working Linux environment. Over the years, RPM use has migrated beyond the Red Hat community to other Linux and Unix environments (including AIX), and has essentially become a de facto standard for distributing software in the open source world.

Yum Won't Be Dropped For Fedora 29

Filed under
Red Hat

There had been plans drafted to finish dropping Yum 3 in Fedora now that DNF is quite mature as the next-generation package manager, but that isn't happening now until at least Fedora 30.

Fedora 29 isn't eliminating Yum since it's a fairly disruptive change at this point in the cycle, there still are some important infrastructure components depending upon Yum like Koji, Pungi, and others, among other logistics to work through.

  • Automotive open source virtualization: Bringing open source virtualization in AGL
    The AGL Software Defined Car Architecture white paper defines how the AGL target platform for software defined vehicles can be implemented by using virtualization techniques, presented in the document along with their automotive benefits, challenges, use cases and requirements. From the beginning, this work objective was to provide an architecture for a virtualization platform that can be used, extended or customized by Tier-1 or OEM companies to reduce time to market.
  • Meltdown Protection For x86 32-bit Aligned For The Linux 4.19 Kernel
    Those still relying upon x86 32-bit Linux kernels for aging hardware and continuing to update to the latest software will find mitigation for the Meltdown CPU vulnerability with the upcoming Linux 4.19 kernel cycle. You'll find this mitigation but at the cost of performance. While x86_64 Linux was mitigated back in January for Meltdown, it's taken a while for x86 32-bit support for KPTI, Kernel Page Table Isolation. This is basically applying the same page table isolation approach seen on Linux x86_64 and ARM to now the 32-bit x86 kernel code. Obviously it hasn't been a priority with many Linux distributions not even bothering with i686 install images in recent years.

Cloud-Native/Kubernetes/Container/OpenShift

  • 10 Key Attributes of Cloud-Native Applications
    Cloud-native platforms, like Kubernetes, expose a flat network that is overlaid on existing networking topologies and primitives of cloud providers. Similarly, the native storage layer is often abstracted to expose logical volumes that are integrated with containers. Operators can allocate storage quotas and network policies that are accessed by developers and resource administrators. The infrastructure abstraction not only addresses the need for portability across cloud environments, but also lets developers take advantage of emerging patterns to build and deploy applications. Orchestration managers become the deployment target, irrespective of the underlying infrastructure that may be based on physical servers or virtual machines, private clouds or public clouds. Kubernetes is an ideal platform for running contemporary workloads designed as cloud-native applications. It’s become the de facto operating system for the cloud, in much the same way Linux is the operating system for the underlying machines. As long as developers follow best practices of designing and developing software as a set of microservices that comprise cloud-native applications, DevOps teams will be able to package and deploy them in Kubernetes. Here are the 10 key attributes of cloud-native applications that developers should keep in mind when designing cloud-native applications.
  • Google Embraces New Kubernetes Application Standard
    Once an organization has a Kubernetes container orchestration cluster running, the next challenge is to get applications running. Google is now aiming to make it easier for organizations to deploy Kubernetes applications, through the Google Cloud Platform Marketplace. The new marketplace offerings bring commercial Kubernetes-enabled applications that can be run in the Google cloud, or anywhere else an organization wants. All a user needs to do is visit the GCP marketplace and click the Purchase Plan button to get started. "Once they agree to the terms, they'll find instructions on how to deploy this application on the Kubernetes cluster of their choice, running in GCP or another cloud, or even on-prem," Anil DhawanProduct Manager, Google Cloud Platform, told ServerWatch. "The applications report metering information to Google for billing purposes so end users can get one single bill for their application usage, regardless of where it is deployed."
  • Challenges and Requirements for Container-Based Applications and Application Services
    Enterprises using container-based applications require a scalable, battle-tested, and robust services fabric to deploy business-critical workloads in production environments. Services such as traffic management (load balancing within a cluster and across clusters/regions), service discovery, monitoring/analytics, and security are a critical component of an application deployment framework. This blog post provides an overview of the challenges and requirements for such application services.

Software: Music Tagger MusicBrainz, Pulseaudio, COPR, AV1

  • Music Tagger MusicBrainz Picard 2.0 Ported To Python 3 And PyQt5, Brings Improved UI And More
    MusicBrainz Picard version 2.0 was released after more than 6 years since the previous major release (1.0). The new version was ported to Python 3 and PyQt5 and includes Retina and HiDPI support, improved UI and performance, as well as numerous bug fixes. [...] MusicBrainz Picard 2.0 was ported to Python 3 (requires at least version 3.5) and PyQt5 (>= 5.7). The release announcement mentions that a side effect of this is that "Picard should look better and in general feel more responsive". Also, many encoding-related bugs were fixed with the transition to Python 3, like the major issue of not supporting non-UTF8 filenames.
  • Pulseaudio: the more things change, the more they stay the same
    Such a classic Linux story. For a video I'll be showing during tonight's planetarium presentation (Sextants, Stars, and Satellites: Celestial Navigation Through the Ages, for anyone in the Los Alamos area), I wanted to get HDMI audio working from my laptop, running Debian Stretch. I'd done that once before on this laptop (HDMI Presentation Setup Part I and Part II) so I had some instructions to follow; but while aplay -l showed the HDMI audio device, aplay -D plughw:0,3 didn't play anything and alsamixer and alsamixergui only showed two devices, not the long list of devices I was used to seeing. Web searches related to Linux HDMI audio all pointed to pulseaudio, which I don't use, and I was having trouble finding anything for plain ALSA without pulse. In the old days, removing pulseaudio used to be the cure for practically every Linux audio problem. But I thought to myself, It's been a couple years since I actually tried pulse, and people have told me it's better now. And it would be a relief to have pulseaudio working so things like Firefox would Just Work. Maybe I should try installing it and see what happens.
  • 4 cool new projects to try in COPR for July 2018
    COPR is a collection of personal repositories for software that isn’t carried in Fedora. Some software doesn’t conform to standards that allow easy packaging. Or it may not meet other Fedora standards, despite being free and open source. COPR can offer these projects outside the Fedora set of packages. Software in COPR isn’t supported by Fedora infrastructure or signed by the project. However, it can be a neat way to try new or experimental software. Here’s a set of new and interesting projects in COPR.
  • SD Times Open-Source Project of the Week: AV1
    Open source supporters and companies are teaming up to offer the next general of video delivery. The Alliance for Open Media (AOMEDIA) is made up of companies like Mozilla, Google, Cisco, Amazon and Netflix, and on a mission to create an open video format and new codec called AV1. In a blog post about the AOMedia Video, or AV1, video codec, Mozilla technical writer Judy DeMocker laid out the numbers; within the next few years, video is expected to account for over 80 percent of Internet traffic. And unbeknownst to many, all of that free, high-quality video content we’ve come to expect all across the Internet costs quite a bit for the people providing it via codec licensing fees. The most common, H.264, is used all over the place to provide the compression required to send video quickly and with quality intact.

KDE and GNOME: Kubuntu 18.04 Reviewed, Akademy, Cutelyst and GUADEC

  • Kubuntu 18.04 Reviewed in Linux ( Pro ) Magazine
    Kubuntu Linux has been my preferred Linux distribution for more than 10 years. My attraction to the KDE desktop and associated application set, has drawn from Kubuntu user, to a tester, teacher, developer, community manager and councilor. I feel really privileged to be part of, what can only be described as, a remarkable example of the free software, and community development of an exceptional product. This latest release 18.04, effectively the April 2018 release, is a major milestone. It is the first LTS Long Term Support release of Kubuntu running the “Plasma 5” desktop. The improvements are so considerable, in both performance and modern user interface ( UI ) design, that I was really excited about wanting to tell the world about it.
  • Going to Akademy
    Happy to participate in a tradition I’ve admired from afar but never been able to do myself… until this year. My tickets are bought, my passport is issued, and I’m going to Akademy! Hope to see you all there!

  • GUADEC 2018 Videos: Help Wanted
    At this year’s GUADEC in Almería we had a team of volunteers recording the talks in the second room. This was organized very last minute as initially the University were going to do this, but thanks to various efforts (thanks in particular to Adrien Plazas and Bin Li) we managed to record nearly all the talks. There were some issues with sound on both the Friday and Saturday, which Britt Yazel has done his best to overcome using science, and we are now ready to edit and upload the 19 talks that took place in the 2nd room. To bring you the videos from last year we had a team of 5 volunteers from the local team who spent our whole weekend in the Codethink offices. (Although none of us had much prior video editing experience so the morning of the first day was largely spent trying out different video editors to see which had the features we needed and could run without crashing too often… and the afternoon was mostly figuring out how transitions worked in Kdenlive).
  • GUADEC 2018
    This year I attended my second GUADEC in beautiful Almería, Spain. As with the last one I had the opportunity to meet many new people from the extended GNOME community which is always great and I can’t recommend it enough for anybody involved in the project. [...] Flatpak continues to have a lot of healthy discussions at these events. @matthiasclasen made a post summarizing the BoF so check that out for the discussions of the soon landing 1.0 release. So lets start with the Freedesktop 18.07 (date based versioning now!) runtime which is in a much better place than 1.6 and will be solving lots of problems such as multi-arch support and just long term maintainability. I was really pleased to see all of the investment in BuildStream and the runtime from CodeThink which is really needed in the long term.
