AMQP vs JMS

JMS: only java, it is a specification
AMPQ: universal, it is a protocol, it is open standard for messaging

JMS doesn't define a protocol.

JMS is an API and AMQP is a protocol.

AMQP supports 4 message models: Direct, Fanout, Topic, Headers

Async Operations with `useReducer` Hook

9 March, 2019

We were discussing with @erusev what we can do with async operation when using useReducer() in our application. Our app is simple and we don't want to use a state management library. All our requirements are satisfied with using one root useReducer(). The problem we are facing and don't know how to solve is async operations.

In a discussion with Dan Abramov he recommends Solution 3 but points out that things are fresh with hooks and there could be better ways of handling the problem.

Problem

MacOS X + oh my zsh + powerline fonts + visual studio code (vscode) terminal settings

Thank you everybody, Your comments makes it better

Install oh my zsh

http://ohmyz.sh/

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Motivation

Integrate JMH (Java Microbenchmarking Harness) with Spring (Boot) and make developing and running benchmarks as easy and convinent as writing tests.

Idea

Wrap the necessary JMH boilerplate code within JUnit to benefit from all the existing test infrastructure Spring (Boot) provides. It should be as easy and convinent to write benchmarks as it is to write tests.

TL;DR;
