Blackboard’s Complexity Problems

Commentary by Stephen Downes

This is a fascinating look at some of the complexity behind the scenes in Backboard's code base. It's a mixture of old code and new, of original Blackboard and acquired products, and support for various types of database. It has multiple ways of representing basic entities (like 'person' or 'course'). And I found this dangerous-sounding tidbit: "The software runs on a version of Java which reached its end-of-life several months ago (and will no longer receive any updates, security or otherwise, else the Java version would be still another variable)." All I can say is: eek. Via EdSurge. See also Phil Hill on Blackboard's potential sale.
