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.

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.
