It's extremely common for developers who work in statically typed languages to talk about how much easier their code is to maintain and that the code is self-documenting because of the type system.  However, these same programmers often ta ...

Any software community has a contingent which agrees that tests are a good thing and testing first leads us to a place of stable, predictable software. With this in mind, the biggest complaint I've heard from people is "testing takes too ...

In the post about communicating contracts through enforcing endpoint contracts, we took a look at some basic types which are available in Signet. Today we are going to talk about how to add more information to your types by creating your o ...

What a ride! I spent the last month preparing a talk for and presenting at Lambdaconf. If you haven't been, you should. Of the conferences and coding-related events I have been to, this was probably the coolest, toughest, mind-bendiest on ...

I'm a big proponent of unit testing. This means that any code I can test, I do. When I work in the browser, however, it becomes more challenging to effectively unit test all of the code I write without spinning up an instance of PhantomJS ...
