Eclipse MicroProfile (MP) aims at bringing Microservices to Enterprise Java by developing common standards that MP-compliant vendors then implement . This not only applies for developer APIs but also to interfaces for running, configuring, and managing the servers.

Note: This is an updated version of a post I wrote for my private blog years ago.
While working on the REST API of RHQ a long time ago, I had started writing some integration tests against it. Doing this via pure HTTP calls is very tedious and brittle. So, I was looking for a testing framework to help me and found one that I used for some time. I tried to enhance it a bit to better suit my needs but didn’t really get it to work.
I started searching again and this time found REST Assured, which is almost perfect as it provides a high-level fluent Java API to write tests. REST Assured can be used with the classic test runners like JUnit or TestNG.

Air pollution is a major problem in many cities around the globe. Some people in Stuttgart, Germany have developed cheap smog sensors that people can install on their balconies and other convenient places and then report data to a central site. I have written about that on OpenSource.com. The data is sent to a central server, from where it is visualized on a map. At the time of writing the above article, there was no way of seeing how the value has changed over time. Meanwhile, there is a visualization of the last 24 hours available on the map.

Google Summer of Code (GSoC), for those who are not familiar, is an initiative led by Google to encourage students to participate in Open Source projects during their summer break. Projects like JBoss Community, Eclipse Vert.X or Fedora apply to be a mentoring organization and if selected by Google, are paired with students with whom they will mentor. Selected and successful students will receive a stipend from Google for their participation.
The JBoss community has been participating in GSoC for the past several years, with outstanding success, and I am happy to announce that the JBoss community has once again been selected as a mentoring organization for GSoC 2017. I have written about last year’s results in the past.
