Build your Kubernetes armory with Minikube, Kail, and Kubens

Build your Kubernetes armory with Minikube, Kail, and Kubens

Kubernetes has grown to be a de facto development platform for building cloud-native applications. As developers, we want to be productive from the word go, or, shall we say, from the word code. But to be productive, we must be armed with the right set of tools. In this article, I will take a look at three important tools that should become part of your Kubernetes tool chest, or armory.

Announcing Red Hat CodeReady Studio, the latest evolution of Red Hat Developer Studio

Announcing Red Hat CodeReady Studio, the latest evolution of Red Hat Developer Studio

Red Hat has been shipping a distribution of Eclipse IDE for years now, including all of the great features of Eclipse along with the add-ons, plugins, and tooling that make working with our products easy and enjoyable. These distributions have gone by different names over the years to indicate how they fit into the Red Hat ecosystem, and to tap into the trust that developers have when they think about Red Hat and what a Red Hat product means for them: it’ll be reliable; it’ll have a published lifecycle; it’s built from source; and if you submit a bug, we’ll fix it (and give the fix to the community). This change is no different.

Red Hat CodeReady Studio is the latest evolution of Red Hat Developer Studio, which itself was an evolution of JBoss Developer Studio. We’re proud to include our distribution of Eclipse IDE in the expanding CodeReady portfolio. Based on the latest Eclipse 4.11, with the latest additions of JBoss Tools and end-to-end testing that ensures everything works as expected, developers can count on the same great experience they’ve grown used to. With tools for working with Fuse and other middleware products and connectors for Red Hat OpenShift that enable super-fast, container-native “inner loop” development cycles, CodeReady Studio is absolutely one of the best desktop IDEs an enterprise JavaTM developer can use.

Understanding GCC warnings, Part 2

Understanding GCC warnings, Part 2

In part 1, I shed light on trade-offs involved in the GCC implementation choices for various types of front-end warnings, such as preprocessor warnings, lexical warnings, type-safety warnings, and other warnings.

As useful as front-end warnings are, those based on the flow of control or data through the program have rather inconvenient limitations. To overcome them, flow-based warnings have increasingly been implemented in what GCC calls the “middle end.” Middle-end warnings are the focus of this article.
