"The short answer: This tutorial was written for Node 0.8.x, so not everything here will work for current and future versions of Node. (We're now at Node 0.10.x.). The reason this particular piece of code breaks is that handling of streams has changed slightly between Node 0.8 and Node 0.10. See the answers at http://stackoverflow.com/quest... for in-depth discussion." - Meryn Stol
