The Bazaar

slide-49

The Lessons of Open Source Software

slide-55

slide-56
SLIDE 56
  • 1. Every good work of software starts

by scratching a developer's personal itch.

slide-57
SLIDE 57

"Write programs that do

  • ne thing and do it well."
slide-58
SLIDE 58

"Write programs that do

  • ne thing and do it well."

"Write programs to work together."

  • Douglas McIlroy
slide-59

  • 3. Plan to throw one [version] away;

you will, anyhow.

If you want to succeed, double your failure rate."

  • Thomas J. Watson
slide-63
SLIDE 63
  • 5. When you lose interest in a

program, your last duty to it is to hand it off to a competent successor.

slide-64

  • 7. Release early. Release often. And

listen to your customers.

  • 9. Smart data structures and dumb

code works a lot better than the other way around.

slide-70

"Bad programmers worry about the code. Good programmers worry about data structures and their relationships."

  • - Linus Torvalds

"Write programs to handle text streams, because that is a universal interface."

  • Douglas McIlroy
slide-73
SLIDE 73

"Write programs to handle negotiated message models, because that is a universal interface."

  • ala Douglas McIlroy
slide-74
SLIDE 74
  • 14. Any tool should be useful in the

expected way, but a truly great tool lends itself to uses you never expected.

slide-75
SLIDE 75

"The value of a well- designed object is that the people who use it can do things with it that the designer never imagined."

  • Donald Norman
slide-76
SLIDE 76

"Web architecture is all about serendipity"

  • Stu Charlton
slide-77
SLIDE 77
  • Scratch a (small) itch
  • Throw early iterations away
  • Plan to hand off the project
  • Release early and often
  • Smart messages beats dumb code
  • Build-in serendipitous reuse

  • 19. Provided the development

coordinator has a communications medium at least as good as the Internet, and knows how to lead without coercion, many heads are inevitably better than one.
