Red Hat Leftovers

  • Next DevNation Live: Your Journey to a Serverless World—An Introduction to Serverless, June 7th, 12pm EDT
  • Monitoring Red Hat AMQ 7 with the jmxtrans Agent

    Red Hat AMQ 7 includes some tools for monitoring the Red Hat AMQ broker. These tools allow you to get metrics about the performance and behavior of the broker and its resources. Metrics are very important for measuring performance and for identifying issues that are causing poor performance.

  • The Open Brand Project | The end of the beginning

    Red Hat launched the Open Brand Project late in 2017, and 6 months later we ’ve reached a watershed moment. We're wrapping up our first phase of inviting participation, openly debating opinions and ideas and creating prototypes based on our findings. Our designers have drawn hundreds of hats, and their workspace looks like a fedora-crazed hatter’s studio. From here, we're moving on to the selection, testing and refining of final designs. But there is still much work to do.

  • A daemon-haunted (container) world no longer: Introducing Buildah 1.0

    A little over a year ago, I challenged my engineering team to create a “coreutils” of container images—essentially, a utility that could be used with existing container host tools like cp, make, yum, and more to build Open Container Initiative (OCI) and docker container images. These images could then be stored at container registries and used by a multitude of container runtimes. I told the team that OCI images were nothing more than a tarball of related container-specific files, so asked, why can’t we create a simple tool to build them without running a container daemon? The engineers asked me what to call it and I responded: “just call it builder.” The engineers heard my Boston accent and `Buildah` was born. I am thrilled to announce that we feel Buildah is developed enough to declare a 1.0 release, with the intent to continue adding innovation and features in the future.

  • Streamlio Announces Apache Pulsar 2.0, Red Hat Launches Buildah 1.0, Firefox Experimenting with Two New Projects and More

    Streamlio, "the intelligent platform for fast data", today announces the availability of Apache Pulsar 2.0, which is an "open-source distributed pub-sub messaging system originally created at Yahoo and now part of the Apache Software Foundation". This release "adds new capabilities to Apache Pulsar that support easy development and deployment of modern data-driven applications and demonstrate the maturity and enterprise-class capabilities of Pulsar while delivering significantly better performance, scalability and durability than older messaging platforms such as Apache Kafka, as verified in real-world OpenMessaging benchmark tests." For more info, see the Streamlio blog post. Streamlio will be demonstrating the new functionality in Pulsar 2.0 at booth S8 at the upcoming Data Works Summit in San Jose, CA, June 17–21. 

    Red Hat announced the launch of Buildah 1.0 today. Buildah is a command-line utility that "provides only the basic requirements needed to create or modify Linux container images making it easier to integrate into existing application build pipelines". The container images Buildah builds are "OCI-compliant and can even be built using Dockerfiles. Buildah is a distillation of container development to the bare necessities, designed to help IT teams to limit complexity on critical systems and streamline ownership and security workflows." 

  • Updating Wacom Firmware In Linux

    Working with the Wacom engineers has been a pleasure, and the hardware is designed really well. The next graphics tablet you buy can now be 100% supported in Linux. More announcements soon.

  • All Things Enterprise Cloud Native at Red Hat

    At KubeCon + CloudNativeCon in Copenhagen in early May, we caught up with Red Hat‘s Brandon Philips, to discuss the state of CoreOS and containers as a whole. Philips was previously with CoreOS, which was acquired by Red Hat back in January, and the pairing has focused a good amount of Linux thought leadership on the Kubernetes project. In Copenhagen, he and Diane Mueller, director of community development at Red Hat, sat down to talk about what it’s been like merging the CoreOS and Red Hat teams.

    The CoreOS team, and Red Hat overall has been working closely with the CNCF to expand the capabilities of Kubernetes for enterprise users. One big part of this effort has been the Kubernetes Operators Project, said Philips.

  • From a diary of AArch64 porter — parallel builds

    Imagine that you have a package to build. Sometimes it takes minutes. Other one takes hours. And then you run htop and see that your machine is idle during such build… You may ask “Why?” and the answer would be simple: multiple cpu cores.

    On x86-64 developers usually have from two to four cpu cores. Can be double of that due to HyperThreading. And that’s all. So for some weird reason they go for using make -jX where X is half of their cores. Or completely forget to enable parallel builds.

  • Working with modules in Fedora 28

    The recent Fedora Magazine article entitled Modularity in Fedora 28 Server Edition did a great job of explaining Modularity in Fedora 28. It also pointed out a few example modules and explained the problems they solve. This article puts one of those modules to practical use, covering installation and setup of Review Board 3.0 using modules.

KDE: System Settings Progress, Building a Bridge from Qt to DDS, Find your way to Plasma Mobile

KDE
  • System Settings Progress – June 2018

    These past few months have been full of work on the KCMs. Our developers have been able to tackle more and more of them for the upcoming version of System Settings.

    In the process, there have been a few changes to note. Many of them deal with work that needed to change as we went through. The overall vision of a more clear and concise settings page is still the same. However, I have learned that through compromise we can move forward. That’s what we have been doing.

  • Building a Bridge from Qt to DDS

    In our previous posts, we looked into various aspects of using Qt in a telemetry scenario. Part one focused on reducing message overhead, while part two was about serialization.

    To demonstrate a typical IoT scenario, we used MQTT as a protocol and the Qt MQTT module available in Qt for Automation. However, the landscape of protocols in the automation world is bigger and different protocols provide different advantages, usually with a cost involved.

  • Find your way to Plasma Mobile

    The Plasma Mobile project was started by the KDE community with the goal of becoming a free, user-friendly, privacy-enabling and customizable platform for mobile devices. We are always on the look out for more contributors to help push Plasma Mobile forward. However contributions to Plasma Mobile has high entry barrier due to various reasons, among which are the lack of documentation and easily available open tasks for Plasma Mobile.

    [...]

    We realised that for new contributors these tasks can be hard to find and difficult to navigate through. To help with this we created another task to help potential contributors easily find the tasks they can work on. Thanks to Dimitris Kardarakos, we now have a web-page on plasma-mobile.org which provides a set of question-answer nodes and leaf nodes pointing to various phabricator tasks. This system is based on the code used by Mozilla to power similar website.

Security: Updates, Zip, Android

  • Security updates for Wednesday
  • Loose .zips sink chips: How poisoned archives can hack your computer

    Specifically, the flaws, dubbed "Zip Slip" by its discoverers at security outfit Snyk, is a path traversal flaw that can potentially be exploited to perform arbitrary code execution attacks. It affects certain tools that handle .zip, .tar, .war, .cpio, and .7z formats.

    The programming blunders are present in developer libraries made by Apache, Oracle, and others, which are used by thousands of applications. Patches are available for the libraries, and products and programs using the insecure code should be updated to bring in the fixes and then pushed out to the public so people can install them and be safe.

  • Why Viruses on Android Aren’t Really an Issue

    Android itself is a pretty secure operating system—a statement that has only gotten truer over the last few years. Right out of the box, all mainstream Android phones feature a locked bootloader to prevent access to the system partition. Optional “sideloading” of non-approved apps is also disabled by default.

    Linux hardware manufacturer Purism is reaffirming their commitment this morning to shipping the Librem 5 smart-phone in January.

  • Purism’s Security and Privacy Focused Librem 5 Smartphone Makes Major Strides in Manufacturing and Development

    Purism, the social purpose corporation which designs and produces popular privacy conscious hardware and software, has announced that its groundbreaking Librem 5 smartphone is currently on schedule for its planned January 2019 delivery date seven months after its crowdfunding campaign raised nearly $2.5 million for the project.

    The Librem 5 will be the world’s first community-owned smartphone ecosystem that gives users complete control over their mobile device.

  • If I had an eelo co-founder

    BUT our eelo community is growing fast: we have close to 15 developers working full time, a dozen translators/editors… to reach our targets, and I’m currently limiting this number.

    eelo could grow way faster and way bigger!

    The reason of the current limit is that my available time of work is limited, and my TODO list is growing faster than I can execute.

    Therefore, I need to find solutions until we find enough funding to hire some people to structure all projects more.

Plasma Got Tricks – I like big tricks and I cannot lie

Filed under
KDE
Reviews

The Plasma desktop is fun. Rich, detailed, with loads of goodies to explore and discover and play with. I haven’t really gotten bored with it even after a couple of years of rigorous daily testing. There’s always something new and exciting and useful to do, and you constantly come across fresh, handy aspects of desktop usage you haven’t really thought about. The discovery is progressive, which also helps navigate the Plasma environment, without getting a sensory overload of too many choices.

This article showcases only a small portion of what Plasma can do. But the best part about it is: you can completely ignore all of the above and just use it like a traditional desktop. On a day you feel adventurous, it will welcome you into its fold and uncover its many cool facets. In general, the desktop should be a background thing, a canvas to let you get things done. But it does not have to be boring. In this regard, Plasma proves that practicality and functionality do not have to come at the price of fun. You do not need to sacrifice. On the contrary. It’s one giant basket of Easter eggs. Happy hunting.

  • EXT4/Fscrypt Changes For Linux 4.18: Speck File-System Encryption Being Added

    Theodore Ts'o at Google submitted the feature updates today for the EXT4 file-system and FSCRYPT file-system encryption framework updates for the Linux 4.18 kernel merge window.

    On the EXT4 side are many clean-ups and bug fixes, including better dealing with supported EXT4 file-systems. Those changes are mostly routine maintenance work and nothing too dramatic.

    But the FSCRYPT changes are going to be more controversial for this file-system encryption support relied upon by EXT4, F2FS, etc. The main change with the FSCRYPT support in Linux 4.18 is adding support for Speck128/Speck256 as supported algorithms.

​Where does Java in the enterprise go from here?

Development

Containers, microservices, and serverless may be all the rage in new-style enterprise software development circles. Gartner may have declared Jakarta Enterprise Edition (JEE), formerly J2EE, to be a legacy platform, but more than 10 percent of the most popular websites are still powered by JEE.

If the Eclipse Foundation, the group now directing JEE's future, has its way though, JEE may live on in the cloud. You can teach an old programmer new tricks.

Shifting JEE from Oracle to Eclipse hasn't been easy. Mike Milinkovich, the Eclipse Foundation's executive director, wrote, "The Eclipse Enterprise for Java (EE4J) top-level project has been created, and thirty-nine projects established. We don't yet have all of the source code moved over, but you can follow the steady progress on the project status page."
