Welcome everyone! We hope everyone is excited (or enjoyed if it has already passed) for the Labor Day weekend if you’re in the U.S. There are some great blog posts over the past couple of weeks we want to highlight and a couple of releases as well.

 

Releases

There are two releases we want to highlight in this editorial. The first is the Keycloak 7.0.0 release! You can of course find all the information you need in the release notes.

Next is the update and release of the new Apache Camel website. The website has had a pretty major overhaul with a new design, graphics, layout and look toward the mobile experience. The website source is hosted on GitHub should you wish to contribute.

Blogs

Oddly enough, the blogsphere has been a little quiet the past couple of weeks, must have something to do with summer.

Red Hat Developer Blog

The Red Hat Developer blog has some great information if you haven’t been there. We’re showcasing just few from the past few weeks:

Eric Schabell has observed that there are 5 common questions he's asked when meeting with existing and potential customers. In this series he tackles each one in turn. In part one he'll be answering:

Recent Drools DMN open source engine performance improvements

The Drools community are always looking for ways to improve the performance of the Drools DMN open source engine. They have recently reviewed a DMN use-case where the actual input population of Input Data nodes varied to some degree; this highlighted a suboptimal behavior of the engine, which we improved in recent releases. In this post Matteo Mortari shares their findings.

 

Beginners Guide - Building an Online Retail Web Shop Workshop (Technical Rules)

With the release of Red Hat Decision Manager 7.3 Eric Schabell has started updating his free online workshop, a beginners guide to building an online retail web shop. In this post Eric explains how to create Technical Rules with Red Hat Decision Manager.

One of the latest and most innovative releases of our community has certainly been Quarkus. The project was published just a few months ago and it’s not surprising that it is now the topic of many materials being released in the few weeks. But especially this week, we are lucky not to have just another article or blog post, but several video presentations all discussing using Quarkus in very different context. Enjoy!

In the previous weeks, a few online presentations—part of the Live From DevNation series, were released and are bound to be of interest for many of you, readers, as they all focus on the latest, shiny and bright little gem of our community, Quarkus:

To demonstrate how the rule engine fits into such an environment, the project contributors have launched a series of articles in the last weeks. The first installment was called Drools & jBPM: Kogito, ergo Rules — Part 1: Bringing Drools Further and its followup Drools & jBPM: Kogito, ergo Rules — Part 2: An All-Encompassing Execution Model for Rules  is now available too! Obviously, those two articles will be a perfect warm-up to the previously mentioned video presentation DevNation Live: Introducing Kogito .

 

3Scale your way into CI/CD

In the last weeks, a very nice series of articles on 3Scale have been released. Nicely organized, their use cases or example are around the topics of CI/CD using Jenkins and thus they form a nice, practical and very concrete example on how to use 3Scale:
