Improved Flathub Website Makes It Easier to Find Flatpak Apps

Filed under
Red Hat

It just got a whole heap easier to find and install Flatpak apps on Linux distros like Ubuntu.

A new version of the Flathub website is now live on Flathub.org, albeit in beta.

The improved front-end to what is the de facto Flatpak app store offers search, browsing and install options.

It’s packed with app descriptions, screenshots, browsable categories, search, meta info, and a beautifully fluid design.

  • OpenShift Commons Briefing: Introduction to Quay with Joey Schorr (Red Hat)

    In this briefing, Red Hat’s Joey Schorr gave a in-depth introduction on and demonstration of Quay, CoreOs’ Application Registry for Kubernetes with OpenShift. Quay is an container registry for building, storing, and distributing your private containers to your servers.

  • Latest CRIU for CentOS COPR

    The version of CRIU which is included with CentOS is updated with every minor CentOS release (at least at the time of writing this) since 7.2, but once the minor CentOS release is available CRIU is not updated anymore until the next minor release. To make it easier to use the latest version of CRIU on CentOS I am now also rebuilding the latest version in COPR for CentOS: https://copr.fedorainfracloud.org/coprs/adrian/criu-el7/.

  • Kerberos Sidecar Container

    The challenge facing this team was how best to implement the Kerberos client for processes running in containers, and how to ensure that the authentication remained valid for long running processes.

    For those not familiar with Kerberos, it is essentially a protocol for authentication, commonly used to allow users or systems to connect to other systems. Tickets are used to authenticate, avoiding the storing, or sending, of passwords, and it is based on symmetric key cryptography.

  • Red Hat Summit 2018: Develop Secure Apps and Services

    Red Hat Summit 2018 will focus on modern application development. A critical part of modern application development is of course securing your applications and services. Things were challenging when you only needed to secure a single monolithic application. In a modern application landscape, you’re probably looking at building microservices and possibly exposing application services and APIs outside the boundaries of your enterprise. In order to deploy cloud-native applications and microservices you must be able to secure them. You might be faced with the challenge of securing both applications and back-end services accessed by mobile devices while using third party identity providers like social networks. Fortunately, Red Hat Summit 2018 has a number of developer-oriented sessions where you can learn how to secure your applications and services, integrate single-sign on, and manage your APIs. Session highlights include:

Early Features Begin Receiving Approval For Fedora 29

Filed under
Red Hat

Today was another weekly Fedora Engineering and Steering Committee (FESCo). We had been looking forward to this meeting for a decision on the GNOME auto-suspend by default behavior but there wasn't a quorum and that topic was then diverted until next week. But there were also early Fedora 29 features approved this week.

Fedora To Decide What To Do About GNOME 3.28's Auto-Suspend Default

Filed under
Red Hat

While Ubuntu developers have decided to no longer enable auto-suspend by default as set with the new GNOME 3.28 desktop when running on AC power, Fedora developers are still debating the issue.

While there is certainly overlap between Fedora/RedHat developers and those working on GNOME, including those that sanctioned this upstream change during the GNOME 3.28 cycle, the Fedora Engineering and Steering Committee (FESCo) has now been summoned to voice their opinion on the matter as well as the Fedora Workstation special interest group.

  • F27-20180404 updated Live isos released

    The Fedora Respins SIG is pleased to announce the latest release of Updated 27 Live ISOs, carrying the 4.15.14-300 kernel.

    This set of updated isos will save about 929 MB of updates after install.  (for new installs.)

  • Yum Command Line Options
  • DNF 3: better performance and a move to C++

    It has only been a few years since DNF replaced Yum as the default Fedora package-management tool; that was done for Fedora 22 in 2015, though DNF had been available for several earlier Fedora releases. Since that time, DNF development has proceeded; it started a move from Python/C to all C in 2016 and has made multiple releases over the years. From an outsider's perspective, no major changes seem necessary, which makes the announcement of DNF 3, and a move to C++, a bit surprising to some.

    For many years, Yum was the package-management front-end for many RPM-based distributions, including Fedora and RHEL. But it suffered from poor performance and high memory use; part of that was attributed to its iterative dependency solver. DNF was meant to fix those problems. It uses the libsolv dependency resolution library developed by openSUSE, by way of the hawkey library.

    Though it wasn't a perfect drop-in replacement for Yum, DNF did replace it. But, even though DNF performed better, often much better, than its predecessor, the project continued to focus on making it faster. Ultimately, that's a large part of the reasons behind DNF 3.

  • Fedora 28 beta is ready for you to test

    Fedora 28 has just been released in its beta version. That means it isn’t likely to be completely free of bugs and that you have a chance to participate in ensuring that it’s ready to go public on May 1.

    This news won’t be particularly surprising to the more enthusiastic Fedora users. Fedora’s release cycle is a fairly regular after all. Every six months, more or less, a new Fedora release is published. Many Fedora users have come to expect to see them around May Day and Halloween each year. Yet, while not surprising, the news is still exciting because of a number of new and enhanced features.

Cloud should have killed Red Hat, but is saving it instead

Filed under
Red Hat

Red Hat's secret formula for making billions of dollars selling free software is not-so-secret, as I've recently written. What still remains somewhat shrouded in mystery, however, is what's driving Red Hat's business.

In a word: Cloud.

A year ago, analysts pointed to the cloud as a harbinger of Red Hat's doom. Today, those same analysts are slowly waking up to the opportunity that a multi-cloud world affords the open source giant.

Red Hat Developer Posts Patches As A Baby Step To Converting Linux Kernel To C++

Filed under
Linux
Red Hat

Either as an elaborate April Fool's Day prank or the start of something more, longtime kernel developer David Howells of Red Hat has posted 45 patches that begin the work on porting the Linux kernel to build under a C++ compiler rather than C.

David Howells posted the set of 45 patches to "convert the kernel to C++", with these patches fixing real coding issues and targeting the GCC 8.0 C++ compiler. At this stage though the C++ compiler gets as far as compiling init/main.c to a file... Obviously just the tip of the iceberg. These 45 patches have various fixes for the code to clean up arguments, ensuring the code would be happy under a C++ compiler, etc and amount to around one thousand lines of code shifted.

In total, they've had around 14,000€ (~$17,000) in sales which is not a lot for a game at all. The good news, is that out of the two thousand copies they say they've sold, a huge 14% of them have come from Linux. It's worth noting, that number has actually gone up since we last spoke to them, where they gave us a figure of 11% sales on Linux.

  • IRS Website Crash Reminder of HealthCare.gov Debacle as OMB Pushes Open Source
    OMB is increasingly pushing agencies to adopt open source solutions, and in 2016 launched a pilot project requiring at least 20 percent of custom developed code to be released as open source – partly to strengthen and help maintain it by tapping a community of developers. OMB memo M-16-21 further asks agencies to make any code they develop available throughout the federal government in order to encourage its reuse. “Open source solutions give agencies access to a broad community of developers and the latest advancements in technology, which can help alleviate the issues of stagnated or out-dated systems while increasing flexibility as agency missions evolve over time,” says Henry Sowell, chief information security officer at Hortonworks Federal. “Enterprise open source also allows government agencies to reduce the risk of vendor lock-in and the vulnerabilities of un-supported software,” he adds.
  • Migrations: the sole scalable fix to tech debt.

    Migrations are both essential and frustratingly frequent as your codebase ages and your business grows: most tools and processes only support about one order of magnitude of growth before becoming ineffective, so rapid growth makes them a way of life. This isn't because they're bad processes or poor tools, quite the opposite: the fact that something stops working at significantly increased scale is a sign that it was designed appropriately to the previous constraints rather than being over designed.
