The U.S. defense industry is the inventor of numerous software processes and even a programming language. This series discusses the challenges to using agile in the U.S. defense industry and some ways agile has made a difference. 

Moq is a mocking library for .NET Unit Testing (cue the TDD folks reminding us mocks are unnecessary), and it is by far the most widely used mocking library in .NET (475 million downloads vs 87 million for the next largest, NSubstitute). Yesterday, its author released version 4.20.1; which added nagware and a backdoor to Moq, in a bid to drive up paid usages of Moq through ‘Sponsorships’. 

In the recent interview with Scott Hanselman, Roberta Arcoverde, Head of Engineering at Stack Overflow, revealed the story about the architecture of Stack Overflow. They handle more than 6000 requests per second, 2 billion page views per month, and they manage to render a page in about 12 milliseconds. We imagine they use a microservice solution running in the Cloud with Kubernetes.

Component architectures are an important part of ever modern front-end framework. In this article, I’m going to dissect Polymer, React, Rio.js, Vue.js, Aurelia and Angular 2 components. The goal is to make the commonalities between each solution obvious. Hopefully, this will convince you that learning one or the other isn’t all that complex, given that everyone has somewhat settled on a component architecture.
