Contextually Correlating Events: The Power of Emergent Behavior in Loosely Coupled Systems

Wed Jan 19 16:42:00 2011

One of the real powers of event-based programming is the ability to contextually correlate events. That's a pretty dense phrase. I'm writing this blog post to unpack it a little in my mind. Hopefully it will do you some good as well. Single events, like web:pageview, mail:received, or phone:inbound_call can be interesting. We've made money on Kynetx apps that rely exclusively on these kinds of primitive events. In spite of that, we can create even more interesting applications when we start to correlate one event with another. This is analogous to building Web applications. While there are plenty of

Using Mobile Phones to Find Traffic Jams

Mon Sep 3 11:00:00 2007

Scott Barlow sent me a pointer to this story about using cell phone triangulation data to determine traffic congestion. The Bangalore Traffic Information System is offline at the moment--Slashdot effect, I'm sure. Of course, you can tell more than how congested the roadways are. You can also determine commuting patterns--in aggregate--over time. When they redid I-15 through Salt Lake before the Olympics, all kinds of sensors were embedded in the roads to give UDOT this kind of information. This is a novel use of data that's already there to accomplish the same thing without the additional infrastructure.
