Angular CLI 6 is here! With it, the Angular team has made it much easier to create libraries.
In this article, we show step by step how to create a simple library using Angular CLI 6. Let’s dive right in…
Getting Started with Xamarin.Forms and Azure Mobile App Service
Earlier this month my friend Ryan introduced us to Getting Started with Xamarin Forms and Prism. In that post, Ryan started a mobile application to display blog posts which he called SimpleBlog.
In this article, I would like to continue that demonstration by adding a back-end server to persist and share these blogs. This will be accomplished using Azureโs Mobile App Service which falls within its free tier services.
Yes, you did read that right: you can spin up an Azure account and have access to try out many of Azureโs features. For instance, the example I am going to walk you through today can be hosted indefinitely without costing you anything, and to that, you could add nine more web, mobile, or API services. See https://azure.microsoft.com/en-us/free/ for more information.
There is no way I am going to be able to cover all the possibilities available in an Azure Mobile App service, much less what Azure has to offer. My intent in this post is to help โwhet your appetiteโ on the possibilities by giving a quick overview of just two great frameworks that play great together: the Microsoft.Azure.Mobile.Client mobile framework tied to an Azure Mobile Apps Service….
AWS Lambda with Spring Boot
The typical deployment scenario for a Spring Boot application in AWS involves running the Java application on an EC2 instance 24 hours a day. Of course, the application could be deployed in AWS ECS as a Docker container, but it still runs continuously on an EC2 instance. In each case, the EC2 instances need to be monitored and you pay for compute capacity used by that EC2 instance.
AWS Lambda provides low cost compute with zero maintenance. Lambda runs your code on demand, without provisioned and managed servers. Lambda automatically runs and scales your code. You are charged for every 100ms your code executes and the number of times your code is triggered. If the code isnโt running, you pay nothing.
Lambda has clear cost and maintenance benefits. But what does it take to run the standard Spring Boot application as a Lambda? How does it work? What are the drawbacks? These are the questions that will be answered in this blog through a tangible example…
Encouraging Good Behavior with JUnit 5 Test Interfaces
JUnit 5, released in September of 2017, is the first major release for the popular JUnit testing framework in a little over a decade. I recently presented on JUnit 5 at Lava One Conf in Hawaii in January. If you have heard about JUnit 5, but are not yet familiar with it, you can check out my presentation here, as well as the JUnit 5 User Guides.
While researching for my presentation, one new feature in JUnit 5 really caught my eye was the ability to declare tests on default methods in interfaces. This feature caught my eye because two issues I frequently face are encouraging developers to write automated tests and promoting consistent patterns across the enterprise. In this article we are going to look at how test interfaces can help accomplish both of these goals.

Girl2Girl Wall is a safe, bully-free zone for pre-teen and teen girls to start social networking. The mobile app was built for both Android and iOS platforms using React Native and can …
