  • Let's collaborate! Take the 2020 Red Hat OpenShift Developer Survey now - Red Hat Developer

    We are always looking for ways to understand better how developers create, build, manage, test, and deploy applications on and for Red Hat OpenShift. An important part of that effort is the annual OpenShift Developer Survey, which we’ve just released for 2020.

    Keep reading to learn more about the survey, including highlights of the 2019 survey results and what to expect from the survey this year. We also invite you to participate in our OpenShift developer experience office hours and one-to-one feedback sessions for our developer community and customers.

  • Set up ZFS on Linux with yum | Opensource.com

    I am a Fedora Linux user who runs yum upgrade daily. While this habit enables me to run all the latest software (one of Fedora's four foundations is "first," and it lives up to that), it also highlights any incompatibilities between the ZFS storage platform and a new kernel.

  • What is an open source upstream?

    Within information technology, the term upstream (and related term "downstream") refers to the flow of data. An upstream in open source is the source repository and project where contributions happen and releases are made. The contributions flow from upstream to downstream.

    When talking about an upstream, it's usually the precursor to other projects and products. One of the best-known examples is the Linux kernel, which is an upstream project for many Linux distributions. Distributors like Red Hat take the unmodified (often referred to as "vanilla") kernel source and then add patches, add an opinionated configuration, and build the kernel with the options they want to offer their users.

    In some cases, users get releases or code directly from the upstream. Windows and macOS users who run Firefox, as one example, generally get their software releases directly from Mozilla rather than through a third party. Linux users, on the other hand, often get Firefox packaged for their distribution --and usually with a few changes in the release’s configuration to better integrate Firefox to their desktop environment or otherwise be more suitable for the distribution.

    In some cases, a project or product might have more than one upstream. Red Hat Enterprise Linux (RHEL) releases are based on Fedora Linux releases. The Fedora Project, in turn, pulls from many upstream projects to create Fedora Linux, like the Linux kernel, GNOME, systemd, Podman, various GNU utilities and projects, the Wayland and X.org display servers, and many more.

    The Fedora Project releases a new version of Fedora roughly every six months. Periodically, Red Hat will take a Fedora Linux release and base a RHEL release on that. Rather than starting from scratch with the vanilla sources for the Linux kernel, GNOME, systemd, and the rest Red Hat starts with the Fedora sources for these projects and utilities, which makes Fedora an upstream of RHEL--with a further upstream of the originating projects. Fedora is downstream of these projects and RHEL is downstream of Fedora.

  • Resiliency in Banking : A ‘must have’ for continuity in the new reality (Part 1)

    A degree of digital transformation has occurred in the banking industry, yet it appears that there will never be a resting point. The establishment of a "new normal", where responsiveness to external competitive demands, global events, and customer expectations highlights the need for continued resilience. The pace of technology changes and competition from traditional and new players overlaid with the consumerization of banking services, has led to expansion in the breadth of services offered, along with how and when they can be consumed.

    Social distancing has prompted new realities in banking, with some aversion to access physical branch locations and interface through ATMs (with people reluctant to touch the machine and cash itself). Regardless of these challenges, the customer still demands uncompromised and enhanced capabilities, perceiving that services are always available and instantaneous.

    Customers have an expectation of 24/7 access, and with devices of their own, are independent of location. Correspondingly, while still necessary in some instances, the decline of visits to branch locations has been supplanted by the digital experience - particularly in mobile - making the support and execution of this channel the primary driver of customer satisfaction and usage.

    This transformation has placed organizations under greater pressure than ever to deliver higher-quality applications more often, to scale digital business - all while adhering to security and compliance regulations - exposing internal gaps in both engagement and integration capabilities. Furthermore, the emergence and adoption of remote work, coupled with increased digital banking, extends the security risk surface area and potential exposure to nefarious activity.

    A faster, more agile, secure, and scalable implementation approach involving automation is crucial to creating frictionless experiences that can be more easily deployed, updated, and maintained–helping achieve the business priorities that are needed, and ones that customers demand.

  • Join the space debate: A space race is good for humanity

    As the Distinguished Engineer and CTO for Space Tech at IBM, I think about space a lot, as we enter the new space age. And I don’t think I’m alone in my thoughts. Space innovation and exploration has always been inspiring for humanity. From the time most of us were kids, we’ve asked questions about space: “Are we alone in this universe? Are there other habitable planets in our galaxy? How can we send probes to deep space? How do we get to Mars?”

    The need to answer these questions – and more—is driving innovation in the space industry in new and exciting ways. This year alone we’ve seen vast activities in the space industry all the way from launching mega constellations in space to providing broad band connectivity, to the first private crewed spacecraft to reach the ISS and three different nations launching probes and rovers’ missions to Mars. My team even open sourced two new projects – Space Situational Awareness and Kubesat – to take on some of the issues facing space exploration. This rapid expansion of the private commercial companies, public-private partnerships and advancements in technology are defining a new landscape of the coming space era.

  • systemd-resolved: introduction to split DNS

    Fedora 33 switches the default DNS resolver to systemd-resolved. In simple terms, this means that systemd-resolved will run as a daemon. All programs wanting to translate domain names to network addresses will talk to it. This replaces the current default lookup mechanism where each program individually talks to remote servers and there is no shared cache.

    If necessary, systemd-resolved will contact remote DNS servers. systemd-resolved is a “stub resolver”—it doesn’t resolve all names itself (by starting at the root of the DNS hierarchy and going down label by label), but forwards the queries to a remote server.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
