State of Functions-as-a-Service on Kubernetes (OpenShift Commons Briefing)

If you are interested in serverless computing / Functions-as-a-Service (FaaS), and are not following the OpenShift blog, you should checkout The State of Functions-as-a-Service on Kubernetes.  This video is part of the OpenShift Commons Briefing series, which has a lot of great content for developers who interested in cloud-native applications and microservices running on OpenShift and Kubernetes.

FaaS, or serverless as some call it, is a promising compute paradigm suitable for event-driven scenarios. In this briefing, Red Hat’s Michael Hausenblas and Brian Gracely reviewed the current open source offerings for FaaS on Kubernetes (Apache Open Whisk, kubeless, OpenFaaS, etc.) and discussed the pros and cons, on an architectural level and a user experience (UX) point of view. They also covered the topic FaaS vs. containers from a developers as well as an operators perspective.

This talk builds on material gathered by the Serverless Working Group , which is part of the Cloud Native Computing Foundation (CNCF). CNCF serves as the vendor-neutral home for many of the fastest-growing projects on GitHub, including Kubernetes, Prometheus, and Envoy.

March 2018 ISO C++ Meeting Trip Report (Core Language)

The March C++ ISO Standard meeting this year was back in Jacksonville, Florida.  As usual, Red Hat sent three of us to the meeting: Torvald Riegel, Thomas Rodgers, and myself.  Jonathan Wakely attended via speakerphone.  There were 121 people attending the plenary meeting at the beginning of the week.

This meeting was mostly about new features for C++20, particularly when and how to merge Technical Specifications into the draft standard.  In the core language, the ones trying to make C++20 are Concepts (already partially merged), Coroutines, and Modules.  There was a lot of discussion around all three.

GNU Toolchain Update – Spring 2018

The GNU Toolchain is a collection of programming tools produced by the GNU Project. The tools are often packaged together due to their common use for developing software applications, operating systems, and low-level software for embedded systems.

This blog is part of a series (see: Fall 2017 Update) covering the latest changes and improvements in the components that make up this Toolchain. Apart from the announcement of new releases, the features described here are at the bleeding edge of software development in the tools. This means that it may be awhile before they make it into production releases, and they might not be fully functional yet. But anyone who is interested in experimenting with them can build their own copy of the Toolchain and then try them out.

Apache Camel URI completion in VS Code XML Editor and Eclipse Che

Apache Camel empowers you to define routing and mediation rules in a variety of domain-specific languages, including a Java-based Fluent APISpring or Blueprint XML Configuration files, and a Scala DSL. It also uses URIs to work directly with any kind of Transport or messaging model such as HTTPActiveMQJMSJBI, SCA, MINA or CXF, as well as pluggable Components and Data Format options. Apache Camel is a small library with minimal dependencies for easy embedding in any Java application.
