An Introduction to Kotlin for Serverside Java Developers
Kotlin is one of the newer languages on the JVM from JetBrains, the makers of IntelliJ. It is a statically typed language which aims to provide a blend of OO and FP programming styles. Kotlin compiler creates bytecode compatible with the JVM, allowing it to run on the JVM and interoperate with existing libraries. We present the main features that might appeal to Java developers.

Modeling Uncertainty with Reactive DDD
Vaughn Vernon has written several books on DDD and reactive messaging patterns, and has found that the nature of distributed systems means you must deal with uncertainty. How to respond to a missing message, or a message that is received twice, should be a business decision, and therefore must be part of the domain model.

Improving Testability of Java Microservices with Container Orchestration and a Service Mesh
In enterprise test scenarios, software needs to be tested in the same way as it will run in production. This article provides a practical demonstration of testing Java microservices that are running on Kubernetes with the Istio service mesh. K8s service abstractions enable mocking, and Istio enables us to re-route traffic and inject faulty responses or delays to verify our services' resiliency.

Getting to Know Graal, the New Java JIT Compiler
Oracle have released Graal, a new JIT compiler for Java. For Java developers, Graal can be thought of as several separate but connected projects - it is a new JIT compiler for HotSpot, and also a new polyglot virtual machine, GraalVM. The initial release includes support for JVM bytecode and JavaScript with LLVM, Ruby and R in beta.
