I've really started to think of SOA as the next level of reuse (as I discuss in my latest podcast).
Reusable services may not seem profound, but I think recognition of this achievement is being lost in all the SOA hoopla around making IT match the business, governance, and so on. All that's good and necessary as well, but at the end of the day for us technical people, a big part of the real promise of services is that they help us reuse the work we've already done.
Why is it that components deployed as services are better than the way components have traditionally been used in the past? I've started to discuss this on my wiki in Service Component vs. Reusable Component.
My first installment is: Service Component vs. Reusable Component: Patching.
I hope this will help make SOA make more sense, just in terms of how it helps you make your applications better.[Read More]

What is it that makes stateless session beans and stateless services, well, stateless? Do they truly have no state?
I discuss this on my wiki in Context-Free Methods.
I prefer the term "context-free" to the term "stateless" because all code has state. ... What makes code "stateless" is that it doesn't know what context it's in ... Any necessary context is passed in from the caller.Hopefully interesting and even a bit educational. Check it out.[Read More]
IBM has actually made a movie about SOA and it premiers today.
The movie, Launch, has its own Web site, SOA Launch. You can see the trailer there or on YouTube.
Actually, it's not a full movie, but a Webcast you can register for, "SOA Demystified! Turn Your SOA Projects Into Lasting Business Success With Higher-Value Services." This is all part of the IBM SOA Marketing Blitz, October 2006.
IBM actually has several items on YouTube:
Those What is SOA? and Mainframe clips are actually reasonably entertaining and do actually teach you something. Check 'em out.[Read More]
What is the fastest growing industrialized nation (population-wise) in the world?
"The United States is the only industrialized nation with significant population growth." The US is the third most populous country, behind China and India. Apparently these countries don't count as industrialized nations. Japan and counties in Europe do, but they're not growing.
And sometime this week, the US population will reach 300 million people. This population growth is being caused not so much by Americans having babies, but primarily by Americans living longer and by people immigrating into America. (The population figures include undocumented residents and other non-citizens.) The environmental impact of so many Americans is cause for concern.

Wish you could read my blog while you go jogging? Probably not. But this might be the next best thing.
I now have an interview in the WebSphere Technical Podcast series, Special episode: Back to Basics on SOA with Bobby Woolf, which I discuss on my wiki. It's audio, so you can listen to me on your computer or take me (well, the interview anyway) with you on your iPod. (What could be better?!)[Read More]
