This is part two in a series of tutorials on programming Haskell. You can get up to speed by reading yesterday's introductory article. Today we'll look more into the basic tools at our disposal in the Haskell language, in particular, operations for doing IO and playing with files and strings. Administrivia Before we get started, I should clarify a small point raised by yesterday's article. One issue I forgot to ...Comment on Article Mentions: Haskell

Using “foldr” in Haskell
InquiryLabs (Jul 17 2008) Explore Article
Author: Duane Johnson 17 Jul I’ve been reading Real World Haskell lately in order to get a better grasp on Haskell and functional programming. It’s a book I’d highly recommend—especially when it’s done! One of the fundamental building-blocks of Haskell is the foldr method which, I am told, is called a “primitive recursive” function because it is capable of building any function in a set of useful recursive functions (e.g. ...Comment on Article Mentions: Haskell

eigenclass - Reexamining qsort, eager vs. lazy algorithm analysis and Ruby's (and other's) GC
eigenclass (Jul 17 2008) Explore Article
The Comonad.Reader article attempted to reconcile the theory with the observation that the "quicksort" based on difference lists scales better than the original one. We came up with the following conjecture: what if the amount of GC work scales superlinearly? The improved function uses less memory and would thus be less affected, if GHC's GC had for instance a term. Ruby's GC, for instance, does work (n being the amount ... -
Haskell Quicksort: A Sort of Difference
DZone (Jul 17 2008) Explore Article
Recently there was a post on eigenclass that was picked up by programming.reddit wherein the author performed an analysis of the classic Haskell quicksort example and tried to reverse the folklore understanding that as classically implemented the quicksort used by most Haskell programmers has an n^2 average case performance. Bowing to Lennart's biases I'll admit the Haskell quicksort is not exactly the same thing and refer to it as "quicksort" ...Comment on Article Mentions: Haskell

Holden Karau: Integrating your HUnit (or other) tests into your cabal package
Holden's Blog (Jul 16 2008) Explore Article
As part of one my side projects I'm working on learning haskell, and creating a simple DNSBL lookup tool. An important part of any project, especially one which you plan to build on top off is its testing. There are quite a few options for Haskell testing such as quickcheck,etc., and the one that I ended up using HUnit. Most developers that I know have been burned at one time ... -
