Haskell programming language
Why the world needs Haskell - Devalot This is a technical review of Haskell and why software developers should care about functional programming. For a non-technical review of why your company should be using Haskell you might want to watch this introduction to Haskell video by FP Complete. TL;DR: Writing high-quality, bug-free software isn’t easy. Haskell (and similar languages) provide the programmer with the tools necessary to get closer than ever before.

The Downfall of Imperative Programming | FP Complete Imperative programming is in my bloodstream. I've been a C++ programmer for most of my life. I wrote a book about C++.
VsHaskell See also [LanguageComparisons]. Haskell Haskell is a modern functional language (like lisp). It's not commonly used but the language is used for some "real" projects (not just an experimental language) and is becoming more common in industry. For example, the darcs version control system is written in Haskell.
I've been trying to learn Haskell lately, and the hardest thing seems to be learning about monads. "Monads in Ruby" and "Monads for Functional Programming" helped me finally to break the ice, but more importantly, they gave me a glimpse behind the veil. I finally began to understand something that is trivial to people such as Philip Wadler, but something that never had been explained to me so succinctly. In computer science, we enjoy using mathematic models, but the science still works if you violate the math. And, much to the dismay of purely functional programming enthusiasts, we almost always do. However, when we embrace the math, sometimes the loss in flexibility is more than compensated for by the increase in functionality.
