Microsoft SQL Server 2012 with HadoopWith the explosion of data, the open source Apache Hadoop ecosystem is gaining traction, thanks to its huge ecosystem that has arisen around the core functionalities of its distributed file system (HDFS) and Map Reduce. As of today, being able to have SQL Server talking to Hadoop has become increasingly important because the two are indeed complementary. While petabytes of unstructured data can be stored in Hadoop taking hours to be queried, terabytes of structured data can be stored in SQL Server 2012 and queried in seconds. This leads to the need to transfer and integrate data between Hadoop and SQL Server. ...

Dependency Injection with AngularJSDependency injection facilitates better testing by allowing us to mock dependencies in testing environments so that we only test one thing at a time. It also enables us to write more maintainable code by decoupling our objects from their implementations. The motivation for using it in AngularJS is to make it easier to transparently load mocked objects in tests.
This book is a practical manual to get you started on dependency injection. It will also take you along the road to creating testable and reusable code. Ensuring productivity and stability are the two most important things that you will learn.
Dependency Injection with AngularJS will introduce you to AngularJS using a simple sample project. By portraying different ways of developing code modules, it will show you the advantages of dependency injection. This will lead to the ability to create reusable components that can easily be tested. ...
