Erik Meijer

Welcome to a new technical series on Channel 9 folded into a different kind of 9 format: C9 Lectures. These are what you think they are, lectures. They are not conversational in nature (like most of what you're used to on 9), but rather these pieces are entirely focused on education,…

In Chapter 2, Dr. Meijer introduces Haskell syntax and notation (via a Haskell implementation called Hugs, to be precise, which is based on Haskell 98) and we learn about the Haskell syntax that represents the fundamental construct of functional programming:functions. It's not like you're used…

Happy Birthday, Channel 9!!! We are 7 years old today! Hard to believe... What a great 7 years it has been. THANK YOU, NINERS! In celebration, we bring you the latest episode of Checking In with Erik Meijer. Our very special guest is Eric Lippert. To Erik, thank you for some many years of great…

Larry Osterman is a legend and one of Channel 9's favorite personalities - it's been too long since you've been on C9, Larry! Now, what would happen if C9 hero Erik Meijer interviewed Larry? Well, you'd get the latest episode of Checking In and one heck of a conversation. Oh…

In Chapter 5, Dr. Meijer introduces and digs into List Comprehensions. In mathematics, comprehension notation is used to construct new sets from old sets. In Haskell, you can create new lists from old lists using a similarcomprehension syntax:[x^2 | x <- [1..5]]The above notation represents the…

It's not often that we can get two minds of Erik Meijer's and Herb Sutter's caliber together for an impromptu technical conversation during Christmas break at Microsoft... Well, we did and the next hour or so contains a lot of intelligence, knowledge, wisdom, and passion. This is one…

In Chapter 4, Dr. Meijer teaches us about the art and practice of defining functions. Functions can be defined using conditional expressions and in Haskell conditional expressions must always have an else clause. Functions can also be defined using guarded equations and pattern matching. You will…

It's always a pleasure to get a chance to sit down and geek out with Anders Hejlsberg. Anders is a Microsoft Technical Fellow (a Technical Fellow is the highest ranking technical position at Microsoft) and programming language design master. He's the creator of C# and one of the founders…

In Chapter 3, Dr. Meijer explores types and classes in Haskell. A type is a collection of related values and in Haskell every well-formed expression has a type. Using type inference, these types are automatically calculated at run time. Ifexpression e returns a type t, then e is of type t, e :: t. A…

Erik Meijer and team (developer Wes Dyer, in particular) have created a profound and beautiful .NET library that will take managed event based programming to new levels. Of course, many of you wish that you could write LINQ expressions over events. Well, now you can thanks to Erik's and Wes…
