C9 Lectures: Graham Hutton  How To Be More Productive
Avg Rating: 4.75
(6)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 selffilmed lecture—thank you, Graham! We're honored. This is certainly a… 
C9 Lectures: Dr. Erik Meijer  Functional Programming Fundamentals Chapter 7 of 13
Avg Rating: 5
(15)In Chapter 7, Dr. Meijer teaches us about HigherOrder Functions. A function is called higherorder if it takes a function as an argument and returns a function as a result:twice :: (a > a) > a > atwice f x = f (f x)The function twice above is higher order because it takes a function…

(16)In Chapter 6, Dr. Meijer guides us through the world of recursive functions. In Haskell, functions can be defined in terms of themselves. Such functions are called recursive. For example: factorial 0 = 1factorial (n+1) = (n+1) * factorial nfactorial maps 0 to 1, and any other positive… 
C9 Lectures: Dr. Erik Meijer  Functional Programming Fundamentals Chapter 10 of 13
Avg Rating: 4
(12)In Chapter 10, Declaring Types and Classes, Dr. Meijer teaches us about type declarations, data declarations, arithmetic expressions, etc. In Haskell, a new name for an existing type can be defined using atype declaration:type String = [Char]String is a synonym for the type [Char].Like function… 
YOW! 2011: Simon PeytonJones  Closer to Nirvana
Avg Rating: 5
(11)I caught up with Simon PeytonJones, author of the Glasgow Haskell Compiler (GHC) and a key contributor to the Haskell functional programming language, at YOW! 2011. Simon is a pure functional guy. That said, he's OK with side effects as long as you can control them (so, monads are great!). Simon… 
C9 Lectures: Dr. Ralf Lämmel  Advanced Functional Programming  The Expression Problem
Avg Rating: 4
(10)"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… 
C9 Lectures: Dr. Erik Meijer  Functional Programming Fundamentals Chapter 12 of 13
Avg Rating: 5
(13)In Chapter 12, Lazy Evaluation, Dr. Meijer takes us on a journey into the world of order of evaluation (when expressions are evaluated). In the case of lazy evaluation, computation is delayed until the result of the computation is known to be required. Most programming languages that most of you use… 
Erik Meijer and Matthew Podwysocki  Perspectives on Functional Programming
Avg Rating: 5
(7)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… 
C9 Lectures: Dr. Ralf Lämmel  The Quick Essence of Functional Programming
Avg Rating: 5
(10)We had to cover monads eventually, and there are many great monad tutorials out there (see, for example, here: http://www.haskell.org/haskellwiki/Tutorials#Using_monads). In fact, there are web resources concerned solely with organizing the many monad tutorials available in the wild, and developing… 
C9 Lectures: Dr. Ralf Lämmel  Advanced Functional Programming  Evolution of an Interpreter
Avg Rating: 5
(6)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 informally presented.…
