RubyConf 2008 has come and gone. It was a great opportunity to meet Ruby friends and make new ones.
I think that my talk on Friday afternoon went well. It’s amazing how your perception of the conference changes
when you shift from fretting about your upcoming talk, to relief once it’s done. I don’t know how many times
I’ve given talks to similar audiences, but the butterflies never seem to stay away, and I think that it’s a good thing
since it keeps you on your toes. If you are going to be in western Michigan on the evening of November 25th, I’ll be reprising
this talk at XP West Michigan.
A Quick Sample of RubyConf 2008 Speakers
Greg Pollack has put up a preview of his upcoming “RubyConf Trailer”
RubyConf in 90 Seconds.
As he did earlier for this year’s RailsConf
Gregg did brief video interviews of as many conference speakers as he could. He’s planning to edit these together,
and provide them as kind of a video “Table of contents” to the full talk videos which will be appearing on
the Confreaks web-site. Coby Randquist of Confreaks told me that he expected
all the videos to be available by a week from today.
A Walk Down Memory Lane
Josh Susser, who is another Rubyist with a background in Smalltalk, tweeted
during my talk, that I was “taking a walk down memory lane.” In a way, RubyConf 2008 was very much a walk down memory
lane for me.
Not only did I reminisce in my talk, but I got to see some old familiar faces from the early days of OOPSLA in the 1980s and 1990s.
Allen Otis, who served as the technical half of the team from GemStone presenting MagLev was one. Another was Monty Williams, also
of GemStone. I had a very nice lunch with Monty and his wife on Saturday, along with another more guy who had recently joined GemStone
to work on MagLev, who we probably bored with old war stories.
Things I learned at RubyConf 2008
In no particular order:
Werewolf fever seems to have died off. As far as I could tell, no werewolf games materialized. The two main instigators weren’t there.
Marcel Molina, apparently never was coming, and Chad Fowler, unfortunately, had to stay away due to the sudden death of his father-in-law.
On the other hand, the musicians, some of them former werewolves, were there in force, leading to an enjoyable jam session.
Jim Weirich and I established that I’ve got a year or two on him, although my hair has retained a bit more of its color.
I also found that I wasn’t the oldest attendee, but I won’t reveal his or her identity.
“PragDave” Thomas gave a great talk, challenging the community to “fork Ruby”, that is to spawn some incubator branches of the language
to experiment with new ideas without delaying or derailing the main Ruby language. If some of these forks produced value, they might
have their ideas merged back. Some of his ideas for forks were Ruby-lite, which had lots of cruft which is not often used removed.
Another was Otuby (for optionally typed Ruby), which was different from Charlie Nutter’s Duby
I thought that the most interesting was probably Cluby, or Ruby with Closures. By making some lexical changes to the language, Dave
suggested that Cluby could allow blocks to always be lambda literals, and to allow blocks to be used in many more places, such as
for ANY argument to a method. This would allow control flow to be implemented by methods, for example an if method which took an
argument to be tested, and one or two blocks, to be executed depending on the truthiness of the first argument, or a looping method which
evaluated it’s second block argument as long at the first block argument evaluated to a truthy value.
He also did away with grammar for both method definitions and class/instance variables. Methods would
simply be blocks which would be called when the object received the corresponding method selector in a message.
He acknowledged, that “Smalltalk had already done this.” Which is half-true. Smalltalk alows arbitrary block closures as arguments,
but you need to look at a language like self for the unification of methods and attributes.
There are some talented musicians in the Ruby community. This wasn’t surprising since there seems to be a positive correlation
between talent for programming and talent for music. Jim Weirich is an avid, and accomplished guitarist, and David Chelimsky and Diego Scataglini
blew me away with a cool acoustic jazz guitar duet! I gotta give those guys, some RSpec!
Appropriately enough, since we were so close to Epcot, once again I learned that “it’s a small world after all.” My wife was along
with me, although she didn’t hang out at the conference. On Saturday evening, Deborah and I tagged along with a group which included
Matz and the members of his team who were there as well as a few of us gai-jin. Deborah is half-Japanese, an Air Force brat who spent
a couple of tours of duty in Tokyo during her formative years. She sat next to Matz and they talked a lot in both Japanese and English.
At one point Deborah was telling Matz about some of our Japanese IBM/ex-IBM friends. When she mentioned Kuse-san, who had visited with us
several times when he was here on business, Matz said “I know Kuse-san!” In retrospect this isn’t surprising, since Kuse-san, now the
director of IBM’s Tokyo Research Lab, has a background in object oriented languages.
And to put a cap on a week full of personal memories, Deb and I flew back home on Sunday for an evening from the 1960s with Ed Sullivan, old VW ads, and the “Beatles.”
