Active-Active Configuration

I received a comment on one of my previous posts asking how to run a test class using SpringJUnit4ClassRunner from normal application code (i.e. within a main method). I'll admit, I didn't know how to do this, but my interest was piqued.

Today I made some commitments to present some "lightning-talks" on .NET topics for my local .NET user group. I may be giving some discussions on C# basics, HTML5 topics, LESS(CSS), and JavaScript. Like many others who are working in the presentation/evangelism circuit, I feel that this will help force me into showing off some talents that I do have and learning some things that I currently don't know.

Follow the Evansville .NET User Group homepage for more details.

In my current project, I have classes which are modeled like the following. At some point, a method like getReturnTypeForGetId() is called on classes A and B. Calling the method with A returns Integer as expected, but B returns Serializable.What am I missing here? Am I getting bitten by some heinous erasure thing, or am I just missing out on some sort of generic context-clobbering?EDIT: Adding an over-ridden getId() method to B fixes the problem, but I would still like to understand what I am running into.I've also asked this question on stackoverflow.importjava.io.Serializable;publicclassWeirdTester{staticinterfaceIdentifiable<T extends Serializable>{ T getId();voidsetId(final T id);}staticabstractclassBaseEntity<T extends Serializable>implements Identifiable<T>{private T id;public T getId(){return id;}publicvoidsetId(final T id){this.id= id;}}staticclassAimplements Identifiable<Integer>{private Integer id;public Integer getId(){ret…

In doing some investigation for doing contract-first development for web services on .NET, I ran into the wsdl command-line tool. Unfortunately, I was unable to find its equivalent in the MonoDevelop IDE. I finally did some digging around in the terminal and found the MonoDevelop command-line tools at: /Library/Frameworks/Mono.framework or /Library/Frameworks/Mono.framework/Versions/current/bin.

I'm setting out to learn .NET and get some experience creating a non-trivial project. Microsoft does provide Express (free, Windows-only) editions of the Visual Studio application in a few flavors as well as basic version of IIS with ASP.NET and SQL Server. But, since my current personal development environment is a MacBook Pro (OSX 10.6.7), getting started with development on .NET can actually cost money (mostly due to the Windows tax). The primary development tool for .NET developers on non-Windows systems seems to be Mono with MonoDevelop.The latest stable release of Mono (2.10.1) supports much of the functionality of the .NET 4.0 platform and some portions of Microsoft's extended .NET eco-system: F#, IronRuby, IronPython, ASP.NET MVC(1, 2, and portions of 3).The latest beta build of MonoDevelop (2.6 beta 2) provides a lot of support for developing applications using C# and the rest of the CLR.I'll be using these in the coming months to do some experiments in the creat…
