Sierpinski‘s Triangle

I am enjoying reading the book The Haskell School of Expression. This book teaches Haskell using graphics, multimedia, and so forth. Indeed, it is an interesting approach to teach a functional programming language than Fibonacci series and factorial numbers. After reading the chapter 2 “ Simple Graphics “, I tried to transcript the source code in F#. Boy, I must tell you, I ran into problems. I tried with WPF and F# and it seems to be not a happy marriage. After trying out several things, I chose DirectX and Winforms...Please read more   www.paul-abraham.com/Sierpinski.doc

Caesar Cipher in F# and Haskell

The roman empire Julius Caesar (100 B.C - 44 B.C) used very simple encipher method to communicate with troops. This method substitutes each alphabet of a word with an alphabet from certain position further in alphabet system. If we use displacement-length 2 for the word “apple”,we will get “crrng”. This cipher method is very easy to crack because we have to check only 25 combinations and every language has characteristic distribution for its alphabets, just like finger print.

Implementing Generic Algorithms in Functional Languages

Haskell has the status like Hebrew ,Latin ,or Greek in the natural languages. Knowledge of Haskell will help you understand concepts of functional programming. I am profiting very much Haskell lectures which gave by Erick Meijer.

Generic functions increase reusability and composability . Let us start with the small example and we want write a function that gives biggest element of a given tuple. Well, if we implement this function Haskell.

Is It An Interpretation or Revelation?

In my Life, I heard many times "Coriolan" Overture " (Beethoven), but this interpretation is a magic . Here comes maestro Carlos Kleiber to conduct :

State Monad in F#

I watched Brain Beckman's Web Cast "The Zen of Stateless State"

and wrote example code for State Monad in F#. Please Check

Now, I know, why I don't have an iPod. Thank you Maestro Riccardo Mutti for valuable Insights:)

Concurrent Quicksort in Erlang and F#

Moore’s Law is no more applicable ( http://en.wikipedia.org/wiki/Moore's_law ) since processors are not getting faster and faster. We have now multicore-processors and developers are confronted with new reality. There are dedicated frameworks like Parallel Extension ,Task Parallel Library(by-product of Microsoft Robotics) for Microsoft.net or dedicated programming languages such as Erlang, but the crucial ingredient for success is to modify algorithms to work parallel as possible. We can gauge achieved improvements by applying Amdahls Law(http://en.wikipedia.org/wiki/Amdahl). I am going to implement these algorithms in F# and Erlang.
