Back from PDC, mailbox dealt with, finally some time to post...
As David observes,
for many of us last week was a wonderful whirlwind of Indigo and Don,
blended together from Monday through Thursday. Here are some thoughts...
Like everyone I know, I'm in love with Indigo. The reason is simple: the
layered API hits the sweet spot. It used to be that building distributed
apps meant writing sockets code. Then along came RPC and object RPC systems
that encapsulated grungy details behind a programming model. Hiding the details was
good, the programming model was okay - except when it wasn't. Unfortunately, with
those frameworks, you didn't have much choice. Indigo, in contrast, layers functionality
so that hiding the grungy communication details doesn't mandate a particular high-level
programming model. You get security, reliability, transactions, etc., whether you
choose to deal directly with XML messages, map message bodies to object models, use
simple request/response message exchange patterns or something more complex, or whatever.
In short, you can build communication models the way you want without having to go
back to sockets and do everything yourself. That is exactly where I want to be.
Don's talk introducing SOA on Monday afternoon was the best one I've seen him give
in a long time. I've learned a lot about being a speaker from Don and it was great
to see him deliver that performance.
Finally, I had the pleasure of spending time with Steve Lucco, who works on Indigo
with Don. Steve joined my wife Sarah as a lead vocalist in Band on the Runtime. He's
really really smart and a great guy to hang out with. (Also, Steve's rendition of
CPU Bound gets my vote for most hummable BotR tune, it's been stuck in my head for
