Flow Debt is a leading indicator that provides a view of what is happening inside a delivery system; an important metric for improving software development. This article provides an example how a metric like Flow Debt can be used improperly, i.e. out of their domain, or properly, i.e. context aware usage of Flow Debt with an IT operations team.

Java 9, OSGi and the Future of Modularity (Part 2)

The flagship feature of Java 9 will be the new Java Platform Module System (JPMS). Given the maturity of OSGi there were technical, political and commercial reasons why another Java module system will soon exist. In this article we compare the two from a technical perspective and see how JPMS and OSGi can work together.

Developing Transactional Microservices Using Aggregates, Event Sourcing and CQRS - Part 1

Developing transactional business applications using the microservice architecture is challenging, because domain models, transactions and queries are resistant to functional decomposition. This article describes a way to develop microservices that solves these problems by using Domain Driven Design, Event Sourcing and Command Query Responsibility Segregation (CQRS).

On Abstractions and For-Each Performance in C#

Donald Knuth famously said, “We should forget about small efficiencies, say about 97% of the time”. But when faced with the other 3%, it is good to know what’s going on behind the scenes. So in this article we’ll be taking a dive into the foreach loop.

RXJava by Example

In the ongoing evolution of paradigms for simplifying concurrency under load, the most promising addition is reactive programming, a specification that provides tools for handling asynchronous streams of data and for managing flow-control, making it easier to reason about overall program design. In this article we overcome the learning curve with a gentle progression of examples.
