IBM/Red Hat/Fedora Leftovers

• The modern developer experience

  We hear from many clients that developer productivity and efficiency continue to be pain points. Cloud adoption can help normalize developer experiences across application stacks and runtimes. The path and steps for your developers to push code should be clear, simple, and easy to implement, even on Day 1. The modern developer experience provides a unified and normalized practice with modern tools. Developers thrive in the inner loop where unit tests and code come together, and in a penalty-free runtime execution environment where no one gets hurt, no processes take down precious workloads, and no one knows that it took 20 minutes to resolve that pesky runtime error. The inner loop occurs in a developer workspace that is easy to set up, manage, prepare, maintain, and, more importantly, easy to allocate. If a new developer is added to your squad, they can have all of the mechanical things they need to push code changes into the pipeline on their first day. An important part of the modern developer experience is expressed as Red Hat CodeReady Workspaces, which provides a set of constructs to provision a developer workspace in the cloud where they can perform their inner loop. A save action to a workspace file initiates an inner loop build in their local workspace, and an endpoint for the developer to see their changes quickly.

• Call for Code Daily: Grillo, and how your code can help

  The power of Call for Code® is in the global community that we have built around this major #TechforGood initiative. Whether it is the deployments that are underway across pivotal projects, developers leveraging the starter kits in the cloud, or ecosystem partners joining the fight, everyone has a story to tell. Call for Code Daily highlights all the amazing #TechforGood stories taking place around the world. Every day, you can count on us to share these stories with you. Check out the stories from the week of August 10th:

• Culture of Innovation and Collaboration: Hybrid Cloud, Privacy in AI and Data Caching

  Red Hat is continually innovating and part of that innovation includes researching and striving to solve the problems our customers face. That innovation is driven through the Office of the CTO and includes OpenShift, OpenShift Container Storage and use cases such as the hybrid cloud, privacy concerns in AI, and data caching. We recently interviewed Hugh Brock, research director for the office of the CTO, here at Red Hat about these very topics.

• Fedora program update: 2020-33

  Here’s your report of what has happened in Fedora this week. Fedora 33 has branched from Rawhide. Please update the Release Readiness page with your team’s status. I have weekly office hours in #fedora-meeting-1. Drop by if you have any questions or comments about the schedule, Changes, elections, or anything else.

• Fedora Magazine: Come test a new release of pipenv, the Python development tool

  Pipenv is a tool that helps Python developers maintain isolated virtual environments with specifacally defined set of dependencies to achieve reproducible development and deployment environments. It is similar to tools for different programming languages, such as bundler, composer, npm, cargo, yarn, etc. A new version of pipenv, 2020.6.2, has been recently released. It is now available in Fedora 33 and rawhide. For older Fedoras, the maintainers decided to package it in COPR to be tested first. So come try it out, before they push it into stable Fedora versions. The new version doesn’t bring any fancy new features, but after two years of development it fixes a lot of problems and does many things differently under the hood. What worked for you previously should continue to work, but might behave slightly differently.

• Introduction to cloud-native CI/CD with Tekton (KubeCon Europe 2020)

  If you’re interested in cloud-native CI/CD and Tekton but haven’t had a chance to get hands-on with the technology yet, the KubeCon Europe Virtual event provides an opportunity to do that. Tekton is a powerful and flexible open source framework for creating cloud-native CI/CD pipelines. It integrates with Kubernetes and allows developers to build, test, and deploy across multiple cloud providers and on-premises clusters as shown in Figure 1.

• Introduction to Strimzi: Apache Kafka on Kubernetes (KubeCon Europe 2020)

  Apache Kafka has emerged as the leading platform for building real-time data pipelines. Born as a messaging system, mainly for the publish/subscribe pattern, Kafka has established itself as a data-streaming platform for processing data in real-time. Today, Kafka is also heavily used for developing event-driven applications, enabling the services in your infrastructure to communicate with each other through events using Apache Kafka as the backbone. Meanwhile, cloud-native application development is gathering more traction thanks to Kubernetes. Thanks to the abstraction layer provided by this platform, it’s easy to move your applications from running on bare metal to any cloud provider (AWS, Azure, GCP, IBM, and so on) enabling hybrid-cloud scenarios as well. But how do you move your Apache Kafka workloads to the cloud? It’s possible, but it’s not simple. You could learn all of the Apache Kafka tools for handling a cluster well enough to move your Kafka workloads to Kubernetes, or you could leverage the Kubernetes knowledge you already have using Strimzi.

• OpenShift for Kubernetes developers: Getting started

  If you are familiar with containers and Kubernetes, you have likely heard of the enterprise features that Red Hat OpenShift brings to this platform. In this article, I introduce developers familiar with Kubernetes to OpenShift’s command-line features and native extension API resources, including build configurations, deployment configurations, and image streams.

• Man-DB Brings Documentation to IBM i

  IBM i developers who have a question about how a particular command or feature works in open source packages now have an easy way to look up documentations, thanks to the addition of support for the Man-DB utility in IBM i, which IBM unveiled in late July. Man-DB is an open source implementation of the standard Unix documentation system. It provides a mechanism for easily accessing the documentation that exists for open source packages, such as the Node.js language, or even for commands, like Curl. The software, which can be installed via YUM, only works with open source software on IBM i at the moment; it doesn’t support native programs or commands.

• Making open decisions in five steps

  The group's leader made a decision, and everyone else accepted it. The leader may have been a manager, a team lead, or the alpha in a social group. Was that decision the best one for the group? Did it take all relevant factors into account? It didn’t really matter, because people didn’t want to buck authority and face the ramifications. But this behavior was typical of life in hierarchical systems.

• Wine Developer Begins Experimenting With macOS ARM64 Support

  Over the months ahead with Apple preparing future desktops/laptops with their in-house Apple silicon built on the ARM 64-bit architecture, Wine developers are beginning to eye how to support these future 64-bit ARM systems with macOS Big Sur.  Wine developer Martin Storsjo has been experimenting with the macOS + ARM64 support and has got the code along far enough that "small test executables" can run on the patched copy of Wine. 

Wandboard IMX8M-Plus SBC debuts AI-enabled i.MX8M Plus

echNexion’s “Wandboard IMX8M-Plus” SBC runs Linux or Android on NXP’s new i.MX8M Plus with 2.3-TOPS NPU. Pre-orders go for $134 with 2GB RAM or $159 with 4GB and WiFi/BT, both with 32GB and M.2 with NVMe. In January, NXP announced its i.MX8M Plus — its first i.MX8 SoC with an NPU for AI acceleration — but so far the only product we’ve seen based on it is a briefly teased Verdin iMX8M Plus module from Toradex. Now, TechNexion has opened pre-orders for a Wandboard IMX8M-Plus SBC based on a SODIMM-style “EDM SOM” module equipped with the i.MX8M Plus.
