On Sunday at PG West, David Fetter gave an interesting presentation about recursive queries; he explained step by step how recursive queries can create Mandelbrot sets and solve traveling salesman problems. I had seen these queries before but this is the first time I heard them explained. Interestingly, two levels of recursive queries were used — one recursive query’s output was fed into the next recursive query, which was then fed into the main query.

Hey – nice blog, just looking around some websites, seems a really nice platform you are using. I’m currently using Wordpress for a few of my sites but looking to change one of them over to a platform similar to yours as a trial run.
Hrmm that was weird, my comment got eaten. Anyway I wanted to say that it’s nice to know that someone else also mentioned this as I had trouble finding the same info elsewhere. This was the first place that told me the answer. Thanks.
What a great resource!
You have really great taste on catch article titles, even when you are not interested in this topic you push to read it
I read a article under the same title some time ago, but this articles quality is much, much better. How you do this?
