RubyNation 2008 wrap up

I attended RubyNation 2008 last weekend on Friday and Saturday. It was great to meet up with fellow Rubyists in the Washington DC area. It was also my first time helping to organize a conference – I think we did a pretty good job considering that we did it in a short time and the conference was sold out. We do stand on the shoulders of giants though – we had help from fellow Regional Ruby Conf organizers from around the country – Lone Star, Mountain West, etc. I also wrote a nice app (in Objective-C) to pick the prize winners that I’m codenaming Prizes.

As usual, there was the good practical technical meat from JRuby to testing to DSLs. You can find a links to the speakers and the Ruby frameworks and tools that they mentioned at my links pages (which I took with my Mac bookmarking app Webnote) to post it to both delicious and ma.gnolia.



But, what I found more interesting is the philosophy of programming. Neal Ford who gave the opening keynote related how Ruby helps you capture the essence of your problem while avoiding the ceremony that other languages like Java make you perform and that we should learn the lore of programming. Glenn Vandenberg reminded us that we really should try to fit the tools to the problem and that there is always a benefit and cost to each. Rich Kilmer noted that Ruby is becoming mainstream and that is has grown organically (to our benefit.)

Finally, Stu wrapped up with how Ruby is good overall, but that there are some bad practices / parts of the language that could come back to bite us later especially as Ruby adoption grows. He called out: class attributes (use instance attributes on eigenclasses instead), constants (you can’t change them unlike almost everything else in Ruby), accessing instance variables directly (use accessors), and how procs are treated (he likes Giles’ L alias for lambda but solving the ugliness of using more than one block will likely need change at the VM level.)

As a programmer who lives in both the Ruby and Objective-C worlds, I had the additional takeaway of how much the Objective-C community can learn from Ruby practices. Things like testing, mocking and DSLs are under-utilized but I think have the potential for improving our apps.

Going further and thus wrapping back to Neal’s talk about the lore of programming, I think we owe it to ourselves as programmers to learn other languages, especially the “root” languages like Smalltalk and Lisp and to read “the classics”. Neal mentioned The Mythical Man-Month, Smalltalk Best Practice Patterns, and The Pragmatic Programmer. To that list, I would add Refactoring.

Thanks for everyone who spoke, attended and organized RubyNation 2008! We’ll be having another one in June 2009.

  1. RubyNation 2008 was great. I also think Bryan Liles gave to great lightening talks on Testing and Project management. He was by far the most entertaining speaker at the conference.
