Tap Compare Testing with Diferencia and Java Microservices
“Tap compare” is a testing technique that allows you to test the behavior and performance of the new service by comparing its results against the old service. This article provides an example of using a new open source tool, Diferencia, and mirroring production traffic across both old and new services to compare the difference in result.

Automating Your Java Project Workflow with a Modified Gitflow Branching Model
Gitflow is a collaborative branching model that attempts to exploit the power, speed and simplicity of Git branching. But documentation for Gitflow in an automated build, integrate, and deploy environment is sparse. This article provides a flavor of Gitflow that can be used in an automated build environment.

Adapting Projects to Use C# 8 and Nullable Reference Types
This report is a case study on upgrading a C# 7 class library to C# 8 with nullable reference types. The project used in this case study is a collection of MVVM style base classes, reflection code, and various utility functions. It was chosen because it is reasonably small and has a good mix of idiomatic and unusual C# patterns.

Overcoming RESTlessness
New API protocols like GraphQL, gRPC, and Apache Kafka have risen in popularity as alternatives to REST-inspired HTTP APIs. Instead of seeking to replace REST, the software engineering industry should seek to evolve by building on the maturity of the REST ecosystem while exploiting the technological strengths of the new protocols.

Rewriting an API Gateway Service from Clojure to Golang: AppsFlyer Experience Report
AppsFlyer processes nearly 70+ billion HTTP requests a day, and is built using a microservices architecture style. The entry point to the system that wraps all of the frontend services is a mission-critical (non-micro) service called the API Gateway. This article is an experience reporting of migrating from a Clojure-based gateway to a newly designed Go-based implementation.

Why Do We Need Architectural Diagrams?
Software architecture diagrams, when created well, and sparingly, can greatly improve communication within the development team and with external stakeholders. They require an understanding of the intended audience, and thoughtful restraint on what to include. Resist the temptation to think that diagrams are unnecessary or unhelpful, simply because there have been plenty of cases of bad diagrams.

Super Charge the Module Aware Service Loader in Java 11
Uday Tatiraju describes the service loading mechanism in Java and the changes made to it in order to support the native Java module system. Tatiraju also discusses an experimental library called Susel that can assist developers in building modular and extensible applications that leverage the native Java module system. The library removes the boilerplate code required to locate and load services.
