DRY Your Ember Code with Ember.computed Macros

Ember.js is a very expressive framework that allows for more than one way to implement a feature. Ember computed properties are frequently used, but this can sometimes lead to code that is repetitive. One of my favorite ways for drying up ember code is to use the macros in the Ember.computed module. There are macros […]

Understanding Homoiconicity in Clojure

For my recent LambdaJam workshop on learning Clojure macros from first principles, I created a set of materials exploring the basic concepts. To really understand macros, you first need to have a good understanding of what makes them so powerful — homoiconicity. In this post, we’ll explore that property of the language. Code Is Data; […]

Higher-order Contextual Functions in Clojure

A lot of functions in Clojure take the form (f args1* f2 args2*), where (f args1) represents a context and (f2 args2) represents a computation to perform in that context. I’m going to call this Clojure’s “contextual function” pattern (since I’ve never seen it named before). This pattern is easy to overlook, but it’s powerful, […]

Using CMock when C is Oversensitive

CMock is an extremely useful tool that can make testing C programs nearly painless. Employing CMock is usually straightforward, but here are a few common sticking points and ways to work around them: Calling Functions in the Same Module How do you test a function that calls another function in the same module? Since the […]
