I’m currently read the Ruby Cookbook and found a good explanation for duck typing. You know, the concept to treat objects according to their methods rather their classes/modules. It might be well known to you, but i like to share it anyway.

I just started reading the latest book from the pragmatic programmers: Programming Erlang. In this series of articles, I’m going to summarize and comment on every chapter I read. Enjoy. (The reason I’m doing this in English is that I simply feel like writing some English again and that I hope to reach a larger audience )

What is Erlang and why read that book?

Software written in Erlang is therefore supposed to utilize the power of multi core processors found in today’s and future computers much better than software written in … my precious Ruby? omg.
