From: http://blog.csdn.net/tangboyun/archive/2010/04/03/5447688.aspxFirst of all, it must be declared that the content below is just some of my personal experiences and insights. Limited by my personal experience, it will certainly be somewhat confusing or even misleading. Two days ago, I linked a funny picture of language fans at why learning Haskell/Python makes you a worse programmer, as shown above. At that time, I didn't think about it, but I th

Haskell is a pure functional programming language. Haskell platform is an integrated development environment of Haskell. This document describes how to install Haskell platform. Operating System: Ubuntu 12.04.1 lts; Linux 3.2.0-29-generic-pae 1 download Haskell platform an

Take advantage of the opportunity to reinstall your Linux virtual machine by documenting the process of installing Haskell, and helping readers who are still hesitant to wander outside the Haskell Gate.Basic concepts:Haskell:is a universal functional language, almost able to do whatever kind of development, including command line, GUI, database, Web. Source code can cross platform: Linux,mac, Windows, FreeB

Understanding higher-order functions The higher order function is the important property of Haskell, and it is also the common property of all functional languages, and the higher order function is actually the function of functions, which is the form of a function as a parameter of another function, which is the higher order function. Let's take a look at an example of a function that takes a function and invokes it twice, expressed in a mathematica

F # was built from the most of the mature features of versions like Haskell and provides a huge number of practically-indispensable advantages in comparison: F # runs on. net which provides a concurrent Garbage Collector that can be used for GUI programming. haskell has only non-concurrent GCS that incurs arbitrarily-long stils, rendering it useless for real-world GUI programming. F # inherits librar

Today, when Google searched for information, it accidentally found a funny image of the new version of language fans. In combination with an interesting blog, it was a perfect match. So, put them together. Create a backup file for favorites.

Source Address: Haskell Learning-monadWhat is Monad Haskell is a purely functional language, the advantage of pure function is safe and reliable. The function output is entirely dependent on the input, there is no implicit dependency, and its existence is as perfect as a mathematical formula. But the pure function is isolated from the external environment, even the most basic input and output can not be com

I know, a lot (are there actually many ?) People will think that pure static strong functional language such as Haskell is too serious and abstract. It is only suitable for cold and hard scientific tasks. However, dear Paul Hudak (http://cs-www.cs.yale.edu/homes/hudak/), let us see in a speech named "Haskell and the arts, haskell, the original rigorous thinking,

Brain Hole Time: why there are so many programming languages in the world, that is decadent capitalism in order to increase the majority of people's learning costs and the compilation of the principle is too popular, it is recommended that the University of all courses to eliminate the compiling principle, and swing the razor, all the programming language kicked, In addition to machine language, only two languages are left: Assembler and Haskell (esca
