Here’s another highlight from RubyConf 2007: watching Jamis Buck and Michael Koziarski give a terrific keynote based on their joint blog, The Rails Way. I leaned over to Alan Francis and mentioned how encouraging it is to see young programmers with a solid, confident grasp of design and development principles that I didn’t learn until I was much older. I don’t mean to embarrass either Jamis or Koz by this; I admire them greatly. They make me optimistic about the future of my profession. (And calling them young says more about me than about them, perhaps.)
It’s absolutely certain that the biggest factor in their early maturity as programmers is that they’re just very smart guys. I’m also sure they started programming at a younger age than I did.
But Alan and I think there’s a third factor: Ruby itself. Ruby helps to teach those good programming skills, and makes them easier to learn. I got the chance later to talk to Koz about it, and he enthusiastically agreed.
The first thing I said in my talk on Saturday was that Rails is like an instructional laboratory for how to build good software. I think that’s the thing I like most about Rails. A big part of that is Ruby itself. Ruby, its libraries, and its documentation are filled with examples of clean, well designed code, and Ruby makes it easier than most other languages to create clean code yourself. The community values and encourages it. Ruby teaches good programming by setting the goal, lowering the barrier, and providing a lot of assistance and encouragement.
I was thrilled last year when Chris Pine’s Learn to Program was published, and now _why has taken up the flag with his brilliant Hackety Hack. We should support efforts that are focused on using Ruby to teach children to program. I think it’s the best way available right now to grow a generation of great programmers.
