Top Stories by Colin Clark

Ok, so if you’ve been following along, you’ll already know: Installed RabbitMQ, and Written a Twitter OnRamp that subscribes to a sample Twitter feed and publishes it on RabbitMQ, and Written a RuleBot that takes the tweet and breaks it into chunks, putting the chunks back onto the bus. And now I’m going to show the Esper code that gives us the top URL’s in the last X seconds found in the Twitter feed.  Here’s a screenshot. Here’s some output in text mode (easier to read): Event received: {URL=http:\\cnn.com, Total=731} Event received: {URL=http:\\colinclarkeventprocessing.com, Total=643} Event received: {URL=http:\\rabbitmqm.com, Total=636} Event received: {URL=http:\\cnn.com, Total=738} Event received: {URL=http:\\colinclarkeventprocessing.com, Total=651} Event received: {URL=http:\\rabbitmqm.com, Total=642} Event received: {URL=http:\\cnn.com, Total=742} Event rece...

We visited Hell in between dives, and rather than make my ex-wife room reservations or send out postcards, I thought I’d amplify a few predic... (more)

Cloud vs Grid

IBM Session at Cloud Expo I’ve been getting a lot of email, and there have been some posts on this blog, regarding CEP based services in the cloud. So as we go down this road, I thought it would behoove us to examine what a cloud is and isn’t and what a grid is and isn’t. I found this introductory article from IBM.  It’s a good start.  I’ll be looking for some more articles – if you’ve got anything you’d like to add to this conversation, please feel free to contact me or add your comments below. Personally, my experience with grid comes from Capital Markets and calculating pric... (more)
