Remote Ensemble Testing - How an Experiment Shaped the Way We Work
This article shares how an experiment evolved into a common practice at the workplace, using an experimental approach with remote ensemble testing to get teammates on our cross-functional team more involved in the testing activities of the jointly created product. This all started in the times of a global pandemic where the entire team was working from home.

Measure Outcomes, Not Outputs: Software Development in Today’s Remote Work World
Today’s remote work world calls for a closer look at how to measure software developer productivity. Currently, there is no standard metric and widely used methods are flawed. The author describes how they successfully lead 500+ remote software developers by measuring outcomes, rather than outputs in order to produce the ideal balance between speed and quality code development.

Six Features From Java 12 to 17 to Get Excited About!
Oracle maintains an ambitious release schedule for new versions of Java, having one fixed release every six months. Although frequent, only some versions are considered long-term support, which means they’ll have premium maintenance for three years. In this article, I review some of the language additions between Java 12 and 17, for anyone interested in what’s been happening since Java 11.

Growing an Experiment-Driven Quality Culture in Software Development
Have you ever faced a challenge at work that you weren’t sure how to tackle? Experiments to the rescue! In a complex environment like software development, no one can tell what might work, so we have to try things out. Read this article to learn about key challenges, insights and lessons, and get inspired for your own path to experimentation.

Getting Started with gRPC and .NET
In this article, the author introduces the core concepts behind gRPC and how it can be used with API development. The basic pros and cons of using gRPC instead of REST are also explained with a scenario analysis. The text is illustrated with a step-by-step tutorial on how to use gRPC to develop streaming services in .NET.

Lightweight External Business Rules
Complex enterprise applications usually come with varying business logic. Such conditions and subsequent system actions, known as rules, are ever varying and demand involvement of domain specific knowledge more than technology and programming. The rules must reside outside the codebase, authored by people with core domain expertise with minimal tech knowledge.

Introducing the KivaKit Framework
In this article, we take a brief tour of the KivaKit open source Java microservices application framework. KivaKit is a collection of mini-frameworks designed to work together. Each mini-framework is described in more detail at https://www.kivakit.org as well as on Jonathan Locke’s blog State of the Art.

Microservices — the Letter and the Spirit
Microservices to be a pattern of ‘decoupled services’ managed to get the best out of it (the underlying understanding of the pattern (‘small’ vs ‘decoupled’) forces developers to take certain design decisions that are consistent with these objectives. In this article discuss we will discuss well and poor implementations: ‘small-services’ vs ‘decoupled-services’ or ‘Letter’ vs the ‘Spirit’.

Solutions for Testing Blockchain: Private Blockchains, Permutations, and Shifting Left
Blockchain is an emerging software architecture that has the potential to be a big disruptor in the industry. With change however, comes the added risk of quality issues. As developers and test engineers, we need to be prepared for those changes to better adapt to the new technology and allow for the continued development of software and products through it, without compromising on quality.
