  • 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 |

    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 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.

Linux Candy: Hollywood – fill your console with Hollywood melodrama technobabble

Linux Candy is a series of articles covering interesting eye candy software. We only feature open source software in this series. Some of the programs in this series are purely cosmetic, frivolous pieces of fun. Candy at their finest. But we also include some programs that aren’t purely decorative. There’s a diverse range of programs included in this series. Programs such as eDEX-UI and Variety are actually highly practical programs. ASCIIQuarium has soothing and relaxing qualities for your desktop. Other programs included in this series (such as lolcat, cacafire) are included purely for their decorative qualities. And then there’s some really fun software that just raises a smile or two. Hollywood is a 102 line script that occupies your console with tech geekery. Read more

  • Open Source Defies Conflicts of Interest: Red Hat Tells All

    Only two parts of the guidelines state any sort of limit on company associates, she clarified. The first is that projects use an Open Source Initiative-approved license. The second is that if an associate is asked to sign a third-party contributor agreement, they should check with Red Hat’s legal team.

  • ANZ moves internet banking to Red Hat OpenShift

    The Australia and New Zealand Banking Corporation (ANZ) in October last year turned to Red Hat for help to bring its internet banking proof of concept to life. The bank wanted to modernise its internet banking platform that had passed its end of life and required extended support for some years. Deciding on a Red Hat OpenShift platform, tech area lead for ANZ's digital arm Raghavendra Bhat said the bank wanted to not constrain itself to a cloud-only solution. ANZ has now migrated 30% of its traffic to the platform and within the first hour of go-live, it processed around AU$2.9 billion worth of payments. Speaking with media on Wednesday, Bhat said the bank's expectation is to complete about 80% of the traffic transition onto the new platform by November, with complete transition by March. He said there has been no "cookie-cutter approach" for how it has lifted and shifted the old system onto the new one.

  • Juggling Ansible, OpenShift and K8s? This is for you: Red Hat couples automation to cluster management

    Red Hat is integrating its Ansible automation platform and Advanced Cluster Management for Kubernetes. “We've known people use Ansible and OpenShift and Kubernetes together for years,” Red Hat senior manager Richard Henshall told The Register. “But here we get a bona fide integration between the two.” Typical uses would be to automate deploying system updates, configuring load balancers, or scaling server resources. The integration is in technical preview. “We’ve got the initial plumbing working, so it’s exposed through Advanced Cluster Management (ACM),” said Henshall, referring to the company’s tool for controlling OpenShift clusters and applications.

  • Why it's important to keep the cloud open |

    There's a famous sticker featured on many laptop lids; it goes something like this: "the 'cloud' is just somebody else's computer." There's a lot of truth to that sentiment, but it's not exactly technically accurate. In fact, cloud computing isn't just somebody else's computer; it's somebody else's hundreds and thousands of computers. Years ago, "the cloud" did indeed just refer to the simplified graphic in a flowchart, so the illustrator didn't have to try to accurately depict the multiple networks that comprise the World Wide Web. Now, however, the cloud isn't just describing traffic or small-time remote file storage offers. The cloud of today is a platform of interconnected computational nodes working together to keep containerized Linux images, each running a distinct service (or "microservice" in developer lingo), functioning as applications distributed over the whole world.

  • Full Disk Encryption, without LVM, by default - Call for comments

    Historically Desktop / Server, only configured LUKS full disk encryption with an LVM layer. Thus ones root ext4 filesystem was an LVM volume, on an VG group, on LUKS, on a GPT partition. The upcoming Ubuntu Core 20 has full disk encryption with TPM support. In that configuration ext4 filesystem is created directly on the LUKS volume which is directly on a GPT partitition. For the upcoming HH 21.04 release, I want to change Desktop/Server, to also install in a similar fashion. Specifically such that by default, we simply use ext4+LUKS without LVM. It seems to me that despite having LVM layer, it’s not actually used or appreciated much. Would you be ok with having full-disk encryption without LVM by default?

  • Ubuntu 21.04 Installer Might Allow EXT4 Encryption Without LVM - Phoronix

    An early proposal by Ubuntu/Canonical developer Dimitri John Ledkov is proposing full disk encryption by default without LVM. With Ubuntu Core 20 there is going to be support for TPM-backed full disk encryption created directly on the LUKS volume and in turn directly on a GPT partition without LVM. For Ubuntu 21.04, the developers are looking at changing the Ubuntu desktop/server installers to potentially allow similar EXT4 encryption directly atop LUKS without LVM.

15 Open-Source Push Notification Projects, Alternative to Apple and Google (Firebase) services

A push notification is the message that pops up on your mobile iOS or Android, and sometimes on your desktop or a web browser. It's often used by application publishers and authors to notify the end-user's device about certain event. It looks like SMS text message and local mobile alerts, but they are application oriented only appears to user who use the application. Users can stop any push notification anytime from their mobile settings in the notifications section. However, they are essential for many applications so the user should be selective when selecting the app. Push technology (server push) are technical term for internet-based communication that occurs when a server notifies the client about certain transaction (notification).
