mBsLOG
Welcome to my weblog. It is an unconventional blog in that I am not planning to post daily or weekly, but only as topics of interest emerge. I enjoyed playing a little with my initials and the word blog and am amused by the fact that it is as much something I am slogging through as something I am blogging about. This listing only shows the five most recent posts.
- Here is an index of all the topics with direct links to the post.
- Here are the posts from 2007.
- Here are the posts from 2008.
- Here are the posts from 2009.
- Here are the posts from 2010.
I will try to discipline myself to keep a more or less regular set of reflections coming, but I can't promise. I have disabled commenting and discussion as it ended up being more maintainence and cleanup than I cared to deal with. That doesn't mean your comments and thoughts aren't welcome. Should you wish to comment on what I have said, I will be happy to add your comments verbatim so long as they are not spam. Simply send an email to me at Pitt -- see my home page. I will insert it in the appropriate post with attribution if you wish. Please reference the title and date of the post on which you are commenting. Also, if you want to suggest a topic that might be covered or discussed, let me know and I will try to include it.

Web 2.0 Developments (Feb 2, 2007)
Technology is developing at a rate that makes it difficult to stay abreast of all the possibilities. Two of the most interesting recent developments are in the area of service oriented architectures and asynchronous javascript and XML. There are exciting and frustrating aspects of both of these technologies and I will be exploring them here over the coming months. Let me begin by talking a little bit about each of them.
AJAX is an exciting new technology that allows us to create an almost seamless interface in the browser which provides the user with an application like experience rather than the jarring page renditions of most web experiences. The cost of this facility is a barrage of exchanges back and forth to the web server that puts a tremendous load on the web server. Further, the technology offers the promise of a push experience but can only do this via the use of polling. There are constant rumors about how AJAX might evolve to allow needed updating without polling, but until that develops, it will remain a small niche technique for select kinds of interface updating.
SOA's are supposed to be the next evolution of distributed systems. Recently we have begun to see commentary that suggests that like so many other paradigms, SOA will be DOA. I think the final evaluation is still out. In the late 90's, HP's espeak presented a significant effort in this direction that dies with the many problems HP faced in the market place. Regrettably, this rather elegant, and complete solution has disappeared. The most recent manifestation of SOA as Web Services has made back a lot of ground, but the implementations tend to be weak on the provision of malleable registries that can be used to discover services located on repositories. Until registries begin to appear, the testing and development of webservices or SOAs will languish.
