A blog about software development, Java and open source.
As part of my work on standards under GA4GH , I frequently deal with API specifications, most often written in OpenAPI 3 (OAS 3) . The setup is always similar – there’s a public GitHub repository containing an OAS 3 YAML file and a few common auxiliary files ( .gitignore , LICENSE , CONTRIBUTING.md , and README.md ). Reference implementations of...
I’m a fan of Travis CI and use it for continuous integration across pretty much all my open-source projects on GitHub. From time to time, I need to obtain a URL to a file in the repository in my build, e.g. to point a particular tool to it, in a way that respects branches as well as pull requests...

Unlike the talks I usually...

In the previous post in this series , we examined features of the Stream API added in Java 9. A very useful API that plays well with streams, and was, in fact, used to make streams more robust, is Optional . Let’s explore it with JShell ! Optional provides a container that may or may not contain a...
In the last post in this series , we took a look at the new convenience factory methods for collections in Java 9. Collections play well with the Stream API, which learned a few new tricks since its introduction in Java 8 as well. There are 4 particularly exciting new features – let’s explore them with JShell ! <h2...
