Building Effective Microservices with gRPC, Ballerina, and Go
gRPC is a relatively new implementation of the Remote Procedure Call (RPC) API paradigm. It can play a major role in all synchronous communications between internal microservices. Here we examine key gRPC concepts, their usage, and benefits of having gRPC as an inter-service communication by using a real-world microservice use case.

Functional UI - a Stream-Based Equational Approach
User interface applications can be implemented with an explicit functional relation linking events received by the user interface to the actions to exert on the interfaced systems. Streams by abstracting over time may express that relation concisely. A stream-based implementation is one of the three Functional UI strategies for implementing reliable, well-architected user interface applications.
