  8. “It’s also worth mentioning that there shouldn’t be doubt in

    anybody’s mind at this point that Ruby itself is slow. It’s great that people are hard at work on faster implementations of the language, but right now, it’s tough.” Alex Payne, Twitter
  9. I for one am scared of Ruby because ... it's

    known to be slow, so if you become The Next MySpace, you'll be buying 5 times as many boxes as the .NET guy down the hall. Joel Spolsky
  10. Rails is for the vast majority of web applications Fast

    Enough... I just happen to care much more about free developer cycles and am willing to trade the former for the latter. David Heinemeier Hansson

    problem (rather than a departmental problem) and often written using an Enterprise Software Architecture.”
  16. Enterprise “Enterprise software is software intended to solve an enterprise

    problem (rather than a departmental problem) and often written using an Enterprise Software Architecture.”
  17. Enterprise “Due to the cost of building what is often

    proprietary software, only large organizations attempt to build such software that models the entire business enterprise [...]”
  18. Enterprise “As many business enterprises have similar departments and systems,

    enterprise software is often available as a suite of programs that have attached development tools to modify the common programs for the specific enterprise.”

  24. matz likes merb Merb has a bright future for the

    people who are not satisfied by the fixed ways in Rails. I think that Merb will give users more freedom in a Ruby-ish way of programming.
