What development stack are you using?

I have been deep in the Microsoft camp of development for more than a decade. Occasionally when I look into what my OSS counter-parts are up to I find myself instantly confused by all the various languages and frameworks. To make matters worse a lot of the technologies seem to be fad driven (will Node.js be widely used in three years?). It is unclear to me what OSS development stacks have made it past the honeymoon period and are now in wide adoption.<p>As an example, if you were to ask me what the typical web development stack is for a Microsoft shop I would say:<p>Framework: ASP.Net MVC<p>Language: C#<p>Web Server: IIS 7.5<p>Data Layer: Entity Framework, NHibernate or straight ADO.Net.<p>Database: SQL 2008 Standard<p>OS: Windows Server 2008 Web (for IIS), Windows Server 2008 Standard (for stand-alone SQL), Windows Server 2008 Enterprise (for clustered SQL)<p>Training: Pluralsight has just about everything I need from beginner to advanced to train staff. Alternatively, highest rated books on Amazon using the above keywords also works out really well.<p>Technical Reference: MSDN is the go to technical reference for all of the above products once initial training is complete.<p>So, what is your development stack? What resources would you give your staff for training? If you were a Microsoft guy, where could you go for training on your stack?
