Functional Programming

Joe Albahari is the creator of LINQPad, an application that many of you use in your daily development of .NET applications/services, especially those that employ LINQ in some fashion. It's just a fantastic developer tool for C#; one that C9 celebrity genius and avid LINQPad user Brian…

Tomas Petricek, a PhD student at University of Cambridge focusing on programming models, teaches us about one of his favorite programming languages, F#. The main topic is programming data with F#. You'll learn about Type Providers and Tomas will show how you can easily call REST APIs from F# using…

Over thousands of years, language has evolved in order to provide mankind a mechanism for making it easier to communicate with one another. Today, the world is filled with a wide variety of languages, some of which are radically different from one another, while others bear striking…

Concurrency is a problem that faces all developers as we move to the age of ManyCore processor architectures. Managing state is an important aspect of programming generally and for parallel programming especially. The great Brian Beckman demonstrates three ways of labeling a binary tree with…

"The Expression Problem is a new name for an old problem. The goal is to define a datatype by cases, where one can add new cases to the datatype and new functions over the datatype, without recompiling existing code, and while retaining static type safety (e.g., no casts)." - Philip…

Continuing with the series of conversations filmed in the "social room" at Lang.NEXT 2012, we present Andrei Alexandrescu, Walter Bright, Erik Meijer, and Andrew Adams-Moran discussing/debating various programming topics including pure versus native languages, Haskell, D, and more.…

In part 3 of the Advanced Functional Programming lecture series, Dr. Lämmel focuses on the domain of language interpretation as a method of understanding some important functional programming techniques. As a side effect, some basics of programming language theory are also…

Matthew Podwysocki is a senior consultant for Microsoft platform technologies in the D.C. area. He's been programming since he was a child and has a particular interest and passion for functional programming. Functional programming is all the rage these days. General purpose imperative…

Greg Meredith, a mathematician and computer scientist, has graciously agreed to do a C9 lecture series covering monadic design principles applied to web development. You've met Greg before in a Whiteboard jam session with Brian Beckman. The fundamental concept here is the monad, and Greg…

It's been far too long since we've had some meaty functional programming content on C9. Luckily, none other than Graham Hutton dropped off a present on our doorstep! Dr. Hutton graciously provided Channel 9 with his latest self-filmed lecture—thank you, Graham! We're honored. This is certainly…
