The EPTS Use Case Study

Posted on 11/28/10 7 Comments

Frankly speaking, I don’t consider myself a “contrarian” regarding CEP and EPTS.  I am simply not a corporate marketing person, living by quarterly earnings reports, and can live by principles, not by corporate greed.  I am sad to say that I don’t support the EPTS use case study because of how it is “mismanaged” (in […]

Anti-Knowledge Cultures and the Internet

Posted on 10/12/10 4 Comments

Having visited over 40 countries in my fortunate life, and lived and worked in three very different cultures, the US, Saudi Arabi and Thailand, I have noticed a bit of sadness creeping into my life about what I would call “anti-knowledge cultures”.    Next spring, if all goes according to plan, I’ll be in Tokyo for […]

Strongly Regulate High Frequency Trading

Posted on 05/25/10 10 Comments

In Regulation: Don’t Throw the Baby Out With the Bathwater, Progress CTO John Bates illustrates the principle of advocating a position based on a natural conflict-of-interest and then wrapping “the package” in rhetorical phrases. First of all, the US economy (read individual investors) would be much better off if financial services firms (or anyone) were […]

TIBCO Continues to Lead in the CEP Space

Posted on 05/24/10 No Comments

After months under the specter of civil unrest in Thailand, and more recently nearly a week dominated by a government imposed curfew in Thailand, I was pleased to read Paul Vincent’s post, TUCON2010: Reviewing the reviews, and yet more CEP presentations…” Paul, Alan and the TIBCO event processing team continue to demonstrate why TIBCO is […]

RETE Engines Must Forward and Backward Chain?!

Posted on 03/06/10 16 Comments

In a new development for me, I recently learned that one of the criteria for a “RETE-based rules-engine” to actually be classified as “RETE” is that the software must perform both forward and backward chaining. A well respected rules professional just informed me: If [the rules-engine] is just forward chaining it’s not RETE because the […]

Disadvantages of Rule-Based Systems (Part 1)

Posted on 03/05/10 8 Comments

In Orwellian Event Processing the discussion moved away from my original intent, which was primarily to discuss the vendor-state-of-denial regarding the prior art for processing complex events, and gravitated toward a discussion on the “inefficiencies” of rule-based systems.  I was surprised learn that there are professionals who believe that there is no basis in fact […]

The Power of Events Revisited (Part 1)

Posted on 03/02/10 No Comments

When I first read The Power of Events: An Introduction to Complex Event Processing in Distributed Enterprise Systems by David Luckham I took away three high level ideas: Events are important in business. Events can be processed in a hierarchical way. Rapide is a modeling tool developed at Stanford that can be used to model […]

Well, after a long period of working on a number of operational projects, I’m going to take a break from writing code and actually do some blogging again. For some this is good news (and I quote from a private note): I’m thankful you’ve started blogging again. For a while there I was afraid you’d […]

Orwellian Event Processing

Posted on 02/28/10 16 Comments

Recently we completed the installation and training of an open source Bayesian classifier to replace a rule-based approach to manage forum spam.  In a nutshell, we found the rule-based approach was highly prone to both false positives and false negatives; however, a statistical approach using a Bayesian approach has turned out to be far superior.
