• It actually runs well if setup properly

  I don't have a spare computer so I'm not going to discuss performance or show benchmarks. I am talking about ease of use in getting things setup. [...] No, I'm not nearly ready to give up my Linux servers in production and despite Sam Ramji's recent pleas to their open source vendors not to compete on price but compete on value, I can still fail fast and cheap using open source software and operating systems.

• A lot of open source developers just don't trust Microsoft, just because.

  I am, however, willing to give them the benefit of the doubt. I am part of the slim majority on the above poll who thinks they are sincere.

He sets up a scenario about the development of an online pizza ordering system to show how to "decorate" a pizza with each of the toppings on a list (instead of having to list out every pizza in every possible topping combination). Of course, all of the code is included and explained so you understand exactly what's happening. Finally, there's a demonstration of its usage - a simple call that grabs the stock level/name/cost of each of the items in stock (pizza combinations).
