  • Allowing cc/c++ To Be More Easily Changed Out Has Been Deferred To Fedora 34

    Proposed last year for Fedora 32 was aiming to make it easier to swap out GCC for other alternate compilers (like Clang) by using the update-alternatives functionality on Fedora for handling the /usr/bin/cc and /usr/bin/c++ symbolic links. That work was deferred to Fedora 33 as it wasn't completed in time while now it's been deferred yet again to Fedora 34 next year.

  • Fedora Community Outreach Revamp: Update!

    The Mindshare Comittee [sic] approved the Community Outreach Revamp proposal after incorporating input from the Fedora community. Mindshare nominated four contributors for potential co-leads for the Temporary Task Force (TTF). Two of the four nominees have capacity for the initiative: Sumantro Mukherjee and Mariana Balla. They will be leading the TTF over the course of the revamp.

    Sumantro and Mariana’s primary efforts will be to help organize the multitude of tasks and communications that need to occur for the revamp to be a success. They are meeting weekly along with Marie Nordin, Fedora’s Community Action and Impact Coordinator (FCAIC). Currently, the co-leads are diving into each area of the revamp plan and adding in more concrete tasks, blockers, and taking a look at how to implement the plan strategically.

  • Get schooled on UX: learning the design thinking process at Red Hat

    How does a good designer operate? How can they understand users, challenge their own beliefs, and redefine problems to create effective prototypes?

    This is what Bekah Diring, an interaction designer for Red Hat’s User Experience Design (UXD) team, asked a group of high school students. She and fellow designer Gina Doyle helped lead the first meeting of a UX workshop series for Boston Public School students run by visual designer Mary Shakshober. For years, Red Hat’s Boston office has collaborated with the Boston Private Industry Council to engage students with the tech industry through internships and mentoring programs. After participating as an intern mentor, Shakshober wanted to continue working with the program in a larger capacity.

    She created this workshop series to share the importance of design thinking with students. "The design thinking process is a good way to kick off really any introduction to UX," Shakshober said. "It helps practitioners of UX to think holistically about a process, rather than associating it just with design. Design thinking also helps to build problem solving and communication skills too."

  • Improved configuration and more in Red Hat CodeReady Workspaces 2.3

    Based on Eclipse Che, Red Hat CodeReady Workspaces (CRW) is a Red Hat OpenShift-native developer environment that supports cloud-native development. CodeReady Workspaces 2.3 is now available. For this release, we focused on improving CRW’s configuration options, updating to the latest versions of IDE plugins, and adding new devfiles.

  • OpenShift Virtualization 2.4: A declarative coexistence of virtual machines and containers

    Virtual machines (VMs) on one platform and containers on another, technically, are a relic of bygone times. How about having both on the same platform? In addition, what if that comes with proven open source technologies from the leader itself? Hear me out: dream, no more! All out there who are living in the modern world of 2020 and are fans of Kubernetes and the Red Hat OpenShift Container Platform might be already hearing about OpenShift Virtualization 2.4. If yes, that is so rightly so.

    It is brand new with general availability announced on 17 August 2020, and IT professionals at all levels have extreme appetites for it. The curiosity is all about the declarative coexistence of VMs and containers on OpenShift, which is made possible through the smart engineering put into OpenShift Virtualization 2.4, all for good profitable business reasons. Here, declarative means fully automated deployment through operators with a full lifecycle management maturity level.

    Note that KubeVirt (one of the backbone components), its adjacent capabilities (for example, containerized data importer (CDI) and network add-ons), and its technical preview features have been out for a long time. You can now run Windows guest VMs, Linux guest VMs, containers, and serverless all together, yet leveraging a whole common converged ecosystem of OpenShift through its certified, conformant Kubernetes platform capabilities. Yes, you heard me right.

  • The Rise of the Virtual Meetup

    In a galaxy far, far away, there was a planet plagued by a virus. This virus swept across its population, causing entire countries to lock down and whole industries to stop. But in the midst of all this chaos, came the rise of the virtual meetup…

    This period of lock-down and quarantine has been longer than many of us ever assumed it would be. We were confident that events scheduled in April would be able to happen in September. However now, four months since the World Health Organization (WHO) declared COVID-19 a pandemic, we have come to realize the extent to which we will most likely need to extend our lock-down and remain in some form of isolation longer than initially anticipated.

  • Kubernetes-native Apache Kafka with Strimzi, Debezium, and Apache Camel (Kafka Summit 2020)

    Apache Kafka has become the leading platform for building real-time data pipelines. Today, Kafka is heavily used for developing event-driven applications, where it lets services communicate with each other through events. Using Kubernetes for this type of workload requires adding specialized components such as Kubernetes Operators and connectors to bridge the rest of your systems and applications to the Kafka ecosystem.

    In this article, we’ll look at how the open source projects Strimzi, Debezium, and Apache Camel integrate with Kafka to speed up critical areas of Kubernetes-native development.

  • What is generative AI and how much power does it have

    Generative AI refers to programs that can use existing content like text, audio files, or images to create new plausible content. The MIT Technology review described generative AI as one of the most promising advances in the world of AI in the past decade. Generative AI enables computers to learn the underlying pattern related to the input, and then use that to generate similar content. There are various techniques to do that such as generative adversarial networks (GANS), transformers, and variational autoencoders.

    Let’s talk about GANs before discussing the use cases of generative AI and how daunting it can be for some use cases.

  • What we've learned using OpenShift Container Platform in a hybrid cloud environment for Red Hat IT

    As a principal engineer in Red Hat IT focused on container platforms, I know the benefits of using Red Hat OpenShift firsthand and the value it gives to our organization. Since our OpenShift services were first deployed in August 2016, we have seen many key improvements, such as shorter cycle time from code to production, higher density of applications, and better standardization of application architectures.

    While these successes were important, we knew we had to face our next frontier. Other business drivers were pushing us to deploy OpenShift across a hybrid cloud environment. These factors included improved multi-site resiliency, the ability to support burst resources on public cloud, avoiding vendor lock-in, and being able to use the most cost-effective infrastructure possible. In addition, with OpenShift being the abstraction layer for public and private cloud, we also needed to offer our application teams an OpenShift interface to the entire hybrid cloud environment so that they could meet the evolving business requirements for their applications.

  • Fedora IoT To Be Promoted To An Official Edition With Fedora 33

    For the past few years there has been a Fedora spin for the "Internet of Things" while with Fedora 33 this autumn the Fedora IoT version is being promoted to an official edition.

    As outlined earlier this month, Fedora IoT Edition has matured well and sought promotion this Fedora 33 cycle to become an official spin. Fedora IoT relies upon RPM-OSTree for offering atomic updates, focuses on container-based workloads, and other changes that differentiate it from other Fedora spins while catering for IoT use-cases from industrial gateways to smart city devices.

  • Never too young to start messaging, never too old to play!

    Messaging is vital to how enterprises work because it underpins many essential tasks that a business has to deal with, such as employee records, customer transactions, or banking. Without messaging, it would be nearly impossible to do these simple tasks safely and securely.

    In spite of messaging being so fundamental to the world of computing, it receives little coverage in the classroom, even at the university level. As a result, messaging can seem unfamiliar and inaccessible.

    Ever wished messaging software could be easy to use? In the IBM MQ Developer Experience team, we challenged ourselves to make MQ simple enough to use that our team lead’s nine-and-a-half-year-old could write an MQ program. To make this possible, we wrote an extension for Scratch that uses the IBM MQ REST API to send messages. What we ended up with was a great tool to help people to easily understand messaging in general and IBM MQ in particular.

  • Code@Think video: Modernize your infrastructure with Kubernetes and IBM Cloud Pak for Applications on IBM Z

    Back in May, I participated in IBM Think Digital 2020 with my colleague Filipe Miranda to present a Master Class titled “Modernizing Your Infrastructure with Kubernetes and ICPA on IBM Z.”

    In this 93-minute video, I kick things off by giving a quick tour of IBM Z and then dive into current options available for Kubernetes on Linux on IBM Z and LinuxONE, including Kubic from SUSE, Canonical distribution of Kubernetes, Red Hat OpenShift, and other deployments supported by IBM partners and community. I wrap up by demonstrating how you’d run a simple nginx deployment from a Dockerfile on OpenShift running on IBM Z.

  • OpenShift 101: Introduction, architecture, and operators

    Red Hat OpenShift is an open source container application platform that runs on Red Hat Enterprise Linux CoreOS (RHCOS) and is built on top of Kubernetes. It takes care of integrated scaling, monitoring, logging, and metering functions. With OpenShift, you can do anything that you can do on Kubernetes and much more with OpenShift-specific features.

    OpenShift includes everything you need for hybrid cloud, like a container runtime, networking, monitoring, container registry, authentication, and authorization. I explain how OpenShift can do all of that by introducing its architecture and components.

  • Fedora 33 LTO Support Is Now In Good Shape For Faster, Smaller Packages

    Fedora's plans to make use of link-time optimizations (LTO) by default with the GCC compiler when building Fedora 33 packages is looking like it will successfully pan out.

    Thanks to the upstream GCC support being in quite good shape these days for LTO'ing software due to the upstream work done by SUSE, Red Hat, and others, Fedora 33 should join the likes of openSUSE employing LTO when building their packages. Fedora developers have been working through issues when enabling LTO optimizations while now they have it under control and at least have the list of packages sorted out for the time being to skip in applying link-time optimizations until the bugs in the package or upstream compiler shortcomings are sorted out.

  • Fedora Involvement

    I’m Fedora Test days greatest armchair quarterback and my first task has been understanding the communication channels between key players.

  • Upvoting projects in Copr

    Let’s take a minute of our time and upvote our favorite projects in Copr to appreciate the great work their maintainers put it.

    There are tens of thousands of projects in Copr with vast differences in the quality of packages they provide and how well they are maintained. Many of them are just testing projects without any further purpose, others provide production-ready software valuable for many users. For a long time, we wanted to give projects some badge or a shiny plaque, that would reflect their popularity among users, and I am happy to announce, that we finally launched upvoting (and downvoting) of projects in Copr.


    The highlighted upward arrow signalizes that I already upvoted this project. Similarly, a downvoted project would be highlighted with red color. Click the highlighted arrow to remove your vote, or point your cursor to the score number, it will show you the number of upvotes and the number of downvotes for the project as two separate numbers.

    Do you find the interface intuitive and user-friendly or would you rather like see some improvements done to it? Please, let us know. Currently, there is no copr-cli or API support for upvoting and downvoting projects.

  • More Kubernetes innovation, less service complexity: Operators and the future of Kubernetes

    Kubernetes, the orchestration engine itself, has reached a point of incremental innovation. This is to say that wholesale, quantum leaps of capabilities are no longer taking place directly in the platform. Instead, Kubernetes now provides a solid foundation for innovation on top of and around itself - just like the Linux kernel, OpenStack and Linux containers before it.

    Red Hat continues to help drive this incremental innovation with the Kubernetes project as the second leading corporate contributor, but we have never stopped looking for ways to extend the innovation of Kubernetes outside of the orchestration engine. One of the most obvious ways we’re working to push this innovation envelope is with Kubernetes Operators, built on the backbone of the Operator Framework open source projects.

IBM Services Global CTO and Vice President Bridget Karlin won't go that far but said: "We will see an increase in edge computing due to the sheer quantity of instances compared to centralized cloud centers." How many? IDC forecasts that by 2025 there will be 55.9 billion connected devices. Leading Linux and cloud company Red Hat will be ready.

  • Get your choice of Linux distribution on IBM LinuxONE

    When you first learn about IBM LinuxONE, many of the resources talk about security, resiliency, open source, and innovation. These benefits have been covered extensively. But on a practical level, what distribution of Linux does LinuxONE actually run?

    First, let’s back up for a moment. From a Linux perspective, LinuxONE is a mainframe (like its sister IBM Z, often referred to as the s390x architecture in the open source world) that IBM has developed to exclusively run Linux. This is enforced through specific Integrated Facility for Linux (IFL) processors that only run Linux, and do not run some of your more traditional mainframe operating systems, like z/OS. From there, you can run Linux directly on a Logical Partition (LPAR) from the Processor Resource/System Manager (PR/SM) or, more commonly, on z/VM or KVM. Once that decision is made, you can install Linux.

  • Libre/Open-Source POWER10 Hardware Systems Unlikely Until At Least 2022

MagicMirror: a versatile home information hub

Back in 2014, a Raspberry Pi enthusiast by the name of Michael Teeuw shared his build of a "magic mirror" with the world in a six-part series. The system consisted of a Raspberry Pi and monitor running a web browser in kiosk mode, with a web server that provided a dashboard interface — all stored in a custom-built case with a one-way mirror. Since his post, others around the world have built these devices for their home (including myself), forming both a community and an interesting open-source project. The recent release of MagicMirror2 (MM2) version 2.12.0 gives us an opportunity to learn more about where the project started and where it is today. The MM2 project provides the software to convert what would otherwise be a normal household mirror into a valuable source of information. This information could take the form of drive times, train schedules, daily news, server loads, sports scores, or even the feed from the doorbell when someone is at the door. With the right know-how, the surface can even become interactive through the use of hand gestures or as a touchscreen. Read more

  • Thunderbird implements PGP crypto feature requested 21 years ago

    Mozilla's mail reader Thunderbird has implemented a feature first requested 21 years ago. The somewhat garbled request – "I'd appreciate a plugin for PGP to ede and encrypt PGP crypted messages directly in Mozilla" [sic] – appears to have gone unimplemented due to concerns about US laws that bar export of encryption, debate about whether PGP was the right way to do crypto, and other matters besides. Thunderbird eventually chose to use Enigmail and its implementation of OpenPGP public key email encryption. However, it was an add-on rather than integrated. Commenters in the Bugzilla thread stemming from the request kept the dream of an integrated solution alive, though. Then in October 2019, the Thunderbird blog announced that Thunderbird 78 "will add built-in functionality for email encryption and digital signatures using the OpenPGP standard." Thunderbird 78 emerged in July 2020, and late in August Thunderbird contributor Kai Engert (:KaiE:) posted: "We have released support for OpenPGP email in Thunderbird version 78.2.1. Marking fixed."

  • Upcoming US Holidays (for Mike Taylor)

    This is my last full week at Mozilla, with my last day being Monday, September 21. It’s been just over 7 years since I joined (some of them were really great, and others were fine, I guess).

  • Update on Firefox Send and Firefox Notes

    As Mozilla tightens and refines its product focus in 2020, today we are announcing the end of life for two legacy services that grew out of the Firefox Test Pilot program: Firefox Send and Firefox Notes. Both services are being decommissioned and will no longer be a part of our product family. Details and timelines are discussed below. Firefox Send was a promising tool for encrypted file sharing. Send garnered good reach, a loyal audience, and real signs of value throughout its life. Unfortunately, some abusive users were beginning to use Send to ship malware and conduct spear phishing attacks. This summer we took Firefox Send offline to address this challenge. In the intervening period, as we weighed the cost of our overall portfolio and strategic focus, we made the decision not to relaunch the service. Because the service is already offline, no major changes in status are expected. You can read more here.

  • Mozilla Browser Extension to Track YouTube Recommendations

    It’s easy to get caught up in YouTube as it recommends an endless array of videos, with each one offering you more of the same type of content. But it’s not always the same content. Sometimes the process gets convoluted, and you wind up watching something you have no interest in. Mozilla is curious why this happens and created a browser extension to track YouTube recommendations.
