Performance! 3 reasons to stick to Java 8 for the moment

It is a smart thing to move to newer versions of Java! Support such as security updates and new features are just two of them but there are many more. Performance might be a reason to stick to Java 8 though. In this blog post I'll show some results of performance tests I have conducted showing Java 11 has slower startup times and slightly slower throughput compared to Java 8 when using the same Java code. Native images (a GraalVM feature) have greatly reduced startup time and memory usage at the cost of throughput. You can only compile Java 8 byte-code to a native image though (at the moment).

The Jenkins Build and Delivery Pipeline plugins

Continuous Delivery (CD) is a design practice used in software development to automate and improve the process of software delivery (http://en.wikipedia.org/wiki/Continuous_delivery). Continuous delivery uses the notion of a deployment pipeline in order to validate code. At an abstract level, a deployment pipeline is an automated manifestation of your process for getting software from version control into the hands of your users (http://www.informit.com/articles/article.aspx?p=1621865&seqNum=2). How can such a deployment pipeline be implemented?

In this blog post I'll describe the setup of my environment and my first experience with the Jenkins/Hudson Build and Delivery Pipeline plugins. What it can do to help implement a deployment pipeline and what it won't do for you.
