  • Building an organization that's always learning: Tips for leaders

    In open organizations, informal learning is critical to success. "Informal learning" accounts for all learning that occurs outside a training program, a classroom, or another formalized instruction setting. Unlike the learning in these formalized learning settings, informal learning is unstructured, personal, and voluntary.

    As a result, systematic study of it is difficult. But due to the prevalence and importance of informal learning in workplaces, several researchers have called for additional research into the subject—and particularly for the design of instruments to actually measure informal learning. Such instruments could likewise be useful in open organizations hoping to measure and foster informal learning practices among employees.

  • 9 people for sysadmins to follow on Twitter

    While Twitter certainly isn't the most open source platform, the open source community on the social network brings a lot of great minds together on a daily basis. The site, as I see it, also democratizes access to these brilliant minds since we're all just one @ away.

    Here are nine people whose Twitter accounts are making my pursuit of sysadmin knowledge, and its continued evolution, better. They fall across the spectrum of technology with the one thing they have in common being their passionate, informative, and thoughtful perspective. They share a wealth of knowledge from explaining Linux commands through comics, to applying a PhD's worth of knowledge to making DevOps make sense.

  • Fedora 32 System-Wide Change proposal: x86-64 micro-architecture update
    Fedora currently uses the original K8 micro-architecture (without 3DNow! and other AMD-specific parts) as the baseline....
    
  • Fedora Developers Discuss Raising Base Requirement To AVX2 CPU Support

    An early change being talked about for Fedora 32, due out in the spring of next year, is raising the x86_64 CPU requirements for running Fedora Linux. When initially hearing of this plan, the goal is even more ambitious than I was initially thinking: AVX2.

    A feature proposal for Fedora 32 would raise the x86_64 base-line for their compiler builds to needing AVX2. Advanced Vector Extensions 2 is Intel Sandy Bridge and newer or AMD Jaguar/Bulldozer and newer. This came as quite a surprise even to myself that Fedora is planning to jump straight from their existing AMD K8 baseline to now AVX2-supportive CPUs.

  • Stable docker CE for Fedora 30 are available!

    Do you use docker? If you are using Fedora 30 then I have good news for you. They officially relesed stable docker CE for Fedora 30, yay!

    Most of us have been waiting for stable docker since February, OMG! You can check issue #600 how frustrating most of docker users because we don’t have stable release and unable to use testing or nightly release because of missing containerd.io and forced dev to seek alternatives using old repo (F29) or using Podman as workaround.

  • Outreachy FHP week 7: Pytest, UI enhancements, FAS search

    From Outreachy.org: The theme for this week is “Modifying Expectations”. Outreachy mentors and interns start the internship with a specific set of project goals. However, usually those goals need to be modified, and that’s perfectly fine! Delays to projects happen. Maybe your project turned out to be more complicated than you or your mentor anticipated. Maybe you needed to learn some concepts before you could tackle project tasks. Maybe the community documention wasn’t up-to-date or was wrong. These are all perfectly valid reasons for projects to be a bit behind schedule, as long as you’ve been working full-time on the project. In fact, free and open source contributors have to deal with these kinds of issues all the time. Projects often seem simple until you start working on them. Project timelines are ususally a very optimistic view of what could happen if everything goes exactly as planned. It often doesn’t, but people still make optimistic plans. Modifying your project timeline to set more realistic goals is a skill all contributors need to learn.

    [....]

    I was a beginner in Django when I started working on this project. Earlier I worked on JavaScript-based framework, and switching to Python was a big change for me. So, it was always learning and implementing on my part. Since Django was new to me, I had to learn it fast, at least the core concept. I found some good resources but they were so detailed that at the end of the document, I would have lost interest in some of the topics. Then I found this tutorial, which turned out to be the perfect platform to have an overall grasp of the widely used python framework.

    I learned about containers, their importance and concept of virtualization. How Docker can also be used when we want to deploy an application to an environment. Understood the concept behind it, learned the basic commands and how to deal with multiple Docker containers.

    In the second half of my internship, I improved and wrote tests of the project without having any prior knowledge of the concept at the beginning.

  • Gift ideas for Sysadmin Appreciation Day

    Sysadmin Appreciation Day is coming up this Friday, July 26. To help honor sysadmins everywhere, we want you to share your best gift ideas. What would be the best way a team member or customer could show their appreciation for you? As a sysadmin, what was the best gift you've ever received? We asked our writers the same question, and here are their answers:

    "Whilst working in the Ubuntu community on Edubuntu, I took it upon myself to develop the startup/shutdown sound scheme, which became the default in Ubuntu for, from what I can understand, the next decade. Whilst people had a love-hate relationship with my sound scheme, and rightly so, I had a love-hate relationship with my sound card during the development.

    At the time I had recorded all my sound samples using one sample rate, but my new sound card, as my motherboard had exploded a few days earlier, did not support it. I had two choices, resample all my samples (which I didn't really want to do) or buy a new sound card.

  • Red Hat OpenStack Platform with Red Hat Ceph Storage: Radosbench baseline performance evaluation

    Red Hat Ceph Storage is popular storage for Red Hat OpenStack Platform. Customers around the world run their hyperscale, production workloads on Red Hat Ceph Storage and Red Hat OpenStack Platform. This is driven by the high level of integration between Ceph storage and OpenStack private cloud platforms. With each release of both platforms, the level of integration has grown and performance and automation has increased. As the customer's storage and compute needs for footprints have grown, we have seen more interest towards running compute and storage as one unit and providing a hyperconverged infrastructure (HCI) layer based on OpenStack and Ceph.

    [...]

    Continuing the benchmarking series, in the next post you’ll learn performance insights of running multi-instance MySQL database on Red Hat OpenStack Platform and Red Hat Ceph Storage across decoupled and hyperconverged architectures. We’ll also compare results from a near-equal environment backed by all-flash cluster nodes.

  • The State of Java in Flathub

    For maintainers of Java-based applications in Flathub, it's worth noting that even if you consume the Latest OpenJDK extension in your application, users will not be broken by major updates because OpenJDK is bundled into your Flatpak. The implication of this for users is that they won't see updates to their Java version until the application maintainer rebuilds the application in Flathub.

    If you maintain a Java-based Flatpak application on Flathub, you can consume the latest version of your chosen OpenJDK stream (either LTS or Latest) simply by rebuilding; the latest version of that OpenJDK steam will be pulled in automatically.

  • Kubernetes policy project takes enterprise IT by storm

    An open source compliance as code project has gained a groundswell of popularity over the last six months among enterprise IT pros, who say it simplifies and standardizes Kubernetes policy management.

    The Open Policy Agent (OPA), an open source compliance as code project founded by former VMware employees, was used at Netflix as early as 2017 and accepted into the Cloud Native Computing Foundation (CNCF) as a sandbox project in March 2018. Netflix gave an OPA demonstration at KubeCon in December 2017, and Intuit and Capital One followed at KubeCon in December 2018. After the project advanced to the CNCF's incubating stage in April 2019, and was demonstrated a third time at KubeCon EU in May 2019, it began to generate mainstream buzz.

    [...]

    As Kubernetes environments grow to encompass Istio service mesh and Knative event-based orchestration in what Google calls the open cloud stack, the fact that OPA lends itself to Kubernetes policy enforcement but can expand to include those adjacent utilities boosts its appeal.

  • The Who, What, Where, When, and Why for Mainframe Security [Ed: IBM pays Ponemon for puff pieces]

    For most people, security is a bit of a nuisance. No-one likes having to keep updating their password and then needing to remember the new one. And then there’s all the different passwords that need to be remembered for different things. It all just seems like an administrative nightmare. It just makes getting a day’s work done harder. That’s what most users think right up until the moment there’s a breach. And suddenly the mood has changed. Now everyone wants to know exactly what’s happened. They want to know who has done what, where they’ve done it, when it occurred, how they got in, and a million other questions. Your phone is ringing off the hook. Your e-mail is filling up faster than usual. What can you do? Where can you access the information you need? How do you respond to the incident?

Post-$34 billion acquisition by IBM, Red Hat bets big on India

Filed under
Red Hat

After the International Business Machines Corp. (IBM) completed the acquisition of Red Hat for $34 billion earlier this month, a top executive from the iconic software company with an open source development model has said that it was a "match made in heaven" that will help it accelerate growth globally, including in India.

In India, Red Hat, which specialises in Linux operating systems, has engineering facilities in Pune and Bengaluru.

[...]

Founded in 1993, Red Hat is credited for bringing open source -- including technologies like Linux, Kubernetes, Ansible, Java and Ceph, among others -- into the mainstream for the enterprises.

Today, Red Hat products and services are widely used by government agencies as well as emerging companies in technology, finance, healthcare, civil aviation and other industries.

Armonk, New York-headquartered IBM particularly hopes that Red Hat's open hybrid Cloud technologies would help it position itself as a leading hybrid Cloud provider.

"At the core of what we do is turning projects in the open source communities into products because at the end of the day, our customer is an enterprise software customer," Allessio said.

  • Fedora announces the first preview release of Fedora CoreOS as an automatically updating Linux OS for containerized workloads

    Three days ago, Fedora announced the first preview release of the open-source project Fedora CoreOS as a secure and reliable host for computer clusters. It is specifically designed for running containerized workloads with automatic updates to the latest OS improvements, bug fixes, and security updates. It is secure, minimal, monolithic and is optimized for working with Kubernetes.

    The main goal of Fedora CoreOS is to be a reliable container host to run containerized workloads securely and at scale. It integrates Ignition from Container Linux technology and rpm-ostree and SELinux hardening from Project Atomic Host.

    Fedora CoreOS is expected to be a successor to Container Linux eventually. The Container Linux project will continue to be supported throughout 2019, leaving users with ample time to migrate and provide feedback. Fedora has also assured Container Linux users that continued support will be provided to them without any disruption. Fedora CoreOS will also become the successor to Fedora Atomic Host. The current plan is for Fedora Atomic Host to have at least a 29 version and 6 months of lifecycle.

  • Big Blue’s Red Hat Brings A Big Change Of Heart

    Perhaps, many years hence, we will call the company that, more than any other, created the enterprise computing environment Big Purple now that it has acquired the company that made open source software in the enterprise safe, sane, and affordable.

    Twenty years ago next month, Red Hat went public and everything about enterprise software changed. A company with some tens of millions of dollars in revenues, providing subscription support for a commercial Linux distribution for systems within a few months had a ridiculous market capitalization in excess of $20 billion and the mad dash for open source projects to be commercialized was on.

    Fast forward two decades, and Red Hat is the touchstone for how to work with upstream open source software projects related to datacenter infrastructure and to bring them downstream to harden them to be enterprise grade, package them up, and then sell support for them. Red Hat is by far and away the most successful provider of commercial support for open source code, and has moved well beyond its foundational Enterprise Linux distribution, mostly through key acquisitions including the companies behind the GNU compilers, JBoss application server, the KVM hypervisor, the Gluster parallel file system, the Ceph object storage, the innovative CoreOS Linux distribution, and the Ansible software provisioning tools as well as the OpenShift container controller (a mix of in-house and Kubernetes code these days), the OpenStack cloud controller, and the CloudForms hybrid cloud management system (also largely done in-house). Red Hat, we think, still needs to have a heavy duty open source database management system distribution – perhaps several different ones with different architectural tenets – but it was also perhaps prescient in that it stayed out of the Hadoop storage and data analytics racket, which has not panned out as planned.

  • skuba Dives into Open Source Waters

    SUSE CaaS Platform 4, our next major release is now in beta. It has major architectural improvements for our customers. In the process of planning and developing it, we took a close look at bootstrapping clusters and managing node membership, and we listened to our customers. One of the things we heard from many of them was that they wanted a way to deploy multiple clusters efficiently, by scripting the bootstrap process or by integrating it into other management tools they use.
    To address this, we committed even more strongly to our upstream participation in Kubernetes development. Instead of building SUSE-specific tools as we had in earlier versions, we contributed the efforts of SUSE engineers to the upstream kubeadm component, helping it bridge the gap between its current state and the abilities we had previously implemented in the Velum web interface. Our bootstrap and node management strategy in version 4 is built on kubeadm.

  • An introduction to cloud-native CI/CD with Red Hat OpenShift Pipelines

    Red Hat OpenShift 4.1 offers a developer preview of OpenShift Pipelines, which enable the creation of cloud-native, Kubernetes-style continuous integration and continuous delivery (CI/CD) pipelines based on the Tekton project. In a recent article on the Red Hat OpenShift blog, I provided an introduction to Tekton and pipeline concepts and described the benefits and features of OpenShift Pipelines.
    OpenShift Pipelines builds upon the Tekton project to enable teams to build Kubernetes-style delivery pipelines that they can fully control and own the complete lifecycle of their microservices without having to rely on central teams to maintain and manage a CI server, plugins, and its configurations.

If you’ve been held back by that situation where you need to have someone in operations provision a database for you, then this article will set you free. I’ll show you how to spin up (and wipe out) a MySQL database in seconds using Red Hat OpenShift.

    Truth be told, there are several databases that can be hosted in OpenShift, including Microsoft SQL Server, Couchbase, MongoDB, and more. For this article, we’ll use MySQL. The concepts, however, will be the same for other databases. So, let’s get some knowledge and leverage it.

  • What you need to know to be a sysadmin

    The system administrator of yesteryear jockeyed users and wrangled servers all day, in between mornings and evenings spent running hundreds of meters of hundreds of cables. This is still true today, with the added complexity of cloud computing, containers, and virtual machines.

    Looking in from the outside, it can be difficult to pinpoint what exactly a sysadmin does, because they play at least a small role in so many places. Nobody goes into a career already knowing everything they need for a job, but everyone needs a strong foundation. If you're looking to start down the path of system administration, here's what you should be concentrating on in your personal or formal training.

  • Announcing Fedora CoreOS preview

    On behalf of the Fedora CoreOS Working Group, I'm thrilled to announce the first preview release of Fedora CoreOS. Fedora CoreOS is built to be the secure and reliable host for your compute clusters. It's designed specifically for running containerized workloads without regular maintenance, automatically updating itself with the latest OS improvements, bug fixes, and security updates. The initial preview release of Fedora CoreOS runs on bare metal, QEMU, VMware, and AWS, on x86_64 only. It supports provisioning via Ignition spec 3.0.0 and the Fedora CoreOS Config Transpiler, automatic updates with Zincati and rpm-ostree, and running containers with Podman and Moby. In the coming months, we'll be adding more platforms, building out functionality, and creating documentation to get Fedora CoreOS ready for production use. For now, the Fedora CoreOS preview should not be used for production workloads, and it might change in incompatible ways before the stable release.

  • Build cloud-native apps faster for Kubernetes with Kabanero, a new open source project from IBM

    As companies modernize their infrastructure and adopt a hybrid cloud strategy, they’re increasingly turning to Kubernetes and containers. Choosing the right technology for building cloud-native apps and gaining the knowledge you need to effectively adopt Kubernetes is difficult. On top of that, enabling architects, developers, and operations to work together easily, while having their individual requirements met, is an additional challenge when moving to cloud.
    To lower the barrier of entry for developers to use Kubernetes and to bring together different disciplines, IBM created new open source projects that make it faster and easier for you to develop and deploy applications for Kubernetes.

  • Kubernetes VS PaaS

    If you asked me 3 years ago, I would probably define the professional part of myself as a “Rails developer”. Back then, most of my new projects started with a proof of concept deployed on a free Heroku account. The reason is simple, that was the fastest way to get my Ruby application live. At the same time it was the cheapest (free right?) so that was a no-brainer.
    The last 2.5 years, my work has been mostly on CloudFoundry and Kubernetes. CloudFoundry is an Open Source PaaS solution and Kubernetes is a Container orchestration platform. I work on a project that combines these two (SUSE CloudFoundry runs CloudFoundry on top of Kubernetes). There is an argument I’ve heard more than once regarding running a PaaS on top of Kubernetes and that is: “Why deploy CloudFoundry on top of Kubernetes and not use Kubernetes directly?”. Maybe it’s my science studies, maybe it’s Myth Busters, but I had to test this theory. Thankfully, 2 times a year we get a week to hack on anything we want at SUSE (Check it out) so I got the time I needed a couple of weeks ago.

  • How to earn a promotion as a sysadmin

    There’s plenty of general advice when it comes to career advancement, such as, “Work hard and you’ll get ahead.”

    General advice can start to feel a little pat—too simplistic to put into action, or too difficult to measure. Surely, it’s not as simple as, “Work hard and watch the promotions roll in.” Not to mention, how would you know if it’s the right promotion. Is it one that matches your goals?

    This question becomes particularly important in IT. What if you’re a sysadmin who’s not particularly interested in managing a team of people? Do you grin and bear it while others move up the food chain?
