Today I’d like to present the implementation of the quicksort algorithm, starting from a naive imperative solution and improving it for elegance and clarity. Why quicksort?

What is the first term in the Fibonacci sequence to contain 1000 digits? This is the quesion I’m answering, comparing the Ruby and the Haskell solutions. Let’s see the ruby version first, with an imperative approach. require 'matrix' limit = 10**999 FIBONACCI_MATRIX = Matrix[[1,1],[1,0]] def fibonacci(n) (FIBONACCI_MATRIX**(n-1)) [0,0] end i = 1 i+=1 while [...] Related posts:

Let me introduce you to an old friend of mine: Hpricot Hpricot has saved my life many times when I had to parse (x)html documents and extract information programatically. It features a very nice ruby-ish syntax and a blazingly fast xpath-based parser. Combine it with open-uri, and you’re in for a fun ride creating a [...] Related posts:

Top 5 mac tools for web development

Let me show you my ‘must-have’ list for development-related tools on Mac. 1. MacPorts MacPorts is an essential tool for any serious developer. It’s very similar to the ports system of FreeBSD with a little mixin from gentoo’s portage, though it’s a lot simpler than any of those. It is a source-based package manager with [...] Related posts:
