Diesmal wollen wir unsere SOAP-Services testen. Doch wie teste ich einen Webservice aus einem Unit-Test heraus? Wie baut man einen Integrationstest? Und gibt es da nicht auch noch etwas dazwischen?

How is an expert OO developer to improve on their craft? By learning from other paradigms! These six principles of the functional style also apply to OO. Some are part of good practice already; some express patterns both old and new; all give us different ways of thinking about problems. For developers without expertise in functional programming, examples in Java and C# provide new techniques for writing clear, quality code.

Vue.JS ist in der Szene für Webentwicklung aktuell ein heißes Thema. Neben React und Angular ist Vue aktuell das drittgrößte Framework für Single Page Webanwendungen.
Wir tauchen in dieser Folge in die Technik ein und Fabi und Sebi schildern ihre Erfahrungen mit dem Bauen von Webapps mit Vue.

Part three of a series on modeling Java problems as folds, looking specifically at streams in Java 8.

So why bother with Java EE?

We are going to answer this question by showing how easy it is to build modern Java applications using most of the Java EE specs. And, the key ingredient to succeeding here is Eclipse Microprofile: enterprise Java in the age of microservices.

The application we are going to build is RESTful web API to manage people; it's as simple as that. The standard way to build RESTful web services in Java is by using JAX-RS 2.1 (JSR-370). Consequently, CDI 2.0 (JSR-365) is going to take care of dependency injection, whereas JPA 2.0 (JSR-317) is going to cover the data access layer. And certainly, Bean Validation 2.0 (JSR-380) is helping us to deal with input verification.

About this course
Skip Course Description

In order to be effective, leaders need a high tolerance of complexity. Beyond this, they need to inform their people and the outside world of their strategies, policies and decisions. Effective leaders are often inspiring communicators - their own high tolerance of complexity helps them reduce this complexity to a concise and powerful message.

Your sensemaking mindset is therefore of critical importance to motivate others to follow and support you. Your ability to inspire and convince is largely dependent on the way you frame your message, and on your skills at playing the game of framing and reframing. You will learn from a large variety of (video) cases and analyse a large number of situations where leaders’ communication and sensemaking skills are tested and probed. This will ensure that you are equipped to build winning coalitions in your own organization.

What you'll learn

How to derive a concise message from a complex situation
How to use framing and reframing effectively to achieve your goals 
How to gain support from senior management and your teams
Develop and apply a sensemaking mindset

There’s nothing I can praise about Magit that hasn’t been written in a dozen blogs already, but since Jonas started a kickstarter campaign for it I knew I had to say something. If you use Magit, you already know the greatness of it. And if you don’t, hopefully I can convince you to try it in time to back the campaign.

This person is a backend developer, so for a long time, JavaScript was just a fun little toy that added a bit of frontend trickery that could make things on a web page change color. If JavaScript was being really useful, it would add form validation that helped prevent the wrong information from getting into the database. Eight years ago jQuery blew this person’s mind. JavaScript itself was a language one merely tolerated, but never embraced.

Then JavaScript and its modern frameworks ate backend, frontend, and everything in between, and it was time to re-become a web developer in 2017 — who writes JavaScript.

Hi. I’m an ancient web developer who is learning modern JavaScript. I’ve just gotten started and I’m having a ball, but I’ve also got whiplash. There are a few things I wish I’d understood and accepted about the world of modern JavaScript before I got started.
