Blackboard Wins Patent Suit Against Desire2Learn

edremy writes "Blackboard, the dominant learning management system (LMS) maker, has won its initial suit against Desire2Learn. Blackboard gets $3.1 million and can demand that Desire2Learn stop US sales. (We discussed Blackboard when the patent was issued in 2006) This blog provides background on the suit. Blackboard has been granted a patent that covers a single person having multiple roles in an LMS: for example, a TA might be a student in one class and an instructor in another. You wouldn't think something this obvious could even be patented, but so far it's been a very effective weapon for Blackboard, badly hurting Desire2Learn and generating a huge amount of worry for the few remaining commercial LMSs that Blackboard has not already bought, and open source solutions such as Moodle (Blackboard's pledge not to attack such providers notwithstanding)."

Sure, consumers have allowed companies like Wall-Mart to take off and out-sell smaller companies, but that's the risk of doing business. Letting companies sue each other left and right is not allowing for a free market, and is in the end going to hurt consumers. For example, when Blackboard bought WebCT, they stopped supporting WebCT4 (Blackboard has released WebCT6/BCE6), despite the fact that there are many classes which are not fully compatible with the new version.

The licensing was getting out of hand even pre-acquisition, and my Spidey-Sense tells me we're just about to take it on the chops from Blackboard. This patent, which stakes out the ground for role-based rights as a Blackboard invention, will kill all innovation as well as open source implementations such as Moodle and Sakai, etc. Everyone is going to be afraid for the future of these alternative LMS's, and will be driven to consolidating on a Blackboard platform, which turns out to be rewarding Blackboard for being monopolistic pricks!.

      When Murray Goldberg was hacking Perl scripts at UBC (or whoever he got to do it for him, if) in the early days of what became WebCT, it was motivated out of a genuine desire to extend the reach of education by someone who I believe had a longtime love for teaching. To look at it now, the product would seem quite silly, I'm sure, but it represented the Golden Age of Learning Management Systems.

      I don't know the development internals of WebCT, but it always seemed to me to be a Good Little Idea, but a Bad Bigger Idea. It just didn't scale. It was like there was no architecture, no coherency.

      Near Dawson City in the Yukon Territory, Canada, there is a four story mining dredge that has been designated a historic site. These dredges were incredible Rube Goldberg machines; they were built ad-hoc, with shit hanging all over the place and the next thought-of feature literally bolted on the side of them. They worked, I guess, but they sure weren't pretty.

      WebCT always reminded me of those dredges, a weird world where the next idea is welded on the side of the implementation in the first way someone thought of how to do it. It ends up being this ugly-but-nearly-functional Frankenstein. Maybe I'm being unfair to mining dredges and Frankensteins.

      The biggest barrier to change is, in my experience, faculty who are trained up and comfortable using Blackboard, and who already have their curriculum good to go in Blackboard.

      Students - unite!. Tell your prof that Blackboard sucks, and give them specific reasons why you believe this to be the case. Pressure profs to get whatever the Teaching and Technology/Learning Committee (or whatever it is called at your University) to get a pilot of an alternative LMS underway. Get that prof to pilot some of their courses on the alternative.

      Let's break this monopoly and keep a competitive and innovative LMS landscape, or we'll all be stuck with something that is, emphatically, worse that WebCT. And fsck the USPTO for enabling this horse-shit, even if they are overworked and underpaid. If you don't have the answer, don't pretend you do. Go and find someone to help with evaluation.

    I have also been a blackboard admin for about five years. The above post is 100% true.

    Here is a short list of Blackboard annoyances:

    It produces hundreds of megabytes of absolutely useless logs every day.

    These logs are basically consist of tomcat java core dumps which seemingly happen every second of the day. These java dumps are completely useless unless you are a java programmer, and even if you are a java programmer, blackboard does not provide the source to their jar files. You could probably decompile them, but who would want to given Blackboard's history of suing over IP.

    The built in log archiving utility doesn't work.

    With all of these goddamn logs, you would think proper log management is surely something Blackboard integrates into their product, right? Wrong. They include a nice little log file archiving utility but it contains precisely zero options on how to archive them, and it frequently fails to zero out logs, leaving you with gigabytes of log files after a short time. Many BB admins, including myself, have their own script to manage logs.

    It's built primarily on Tomcat.

    Everything I've ever seen that was built on Tomcat has been either unstable, dog slow, or both. One version of Blackboard shipped with a version of Tomcat that leaked threads, causing BB administrators all over the planet to have to restart the tomcat processes on their BB servers every 7-14 days.

    Their support is nearly non-existent

    Unless you say your server is down, support tickets generally take weeks, and in some cases months to get resolved. Simple ("non-critical") cases are all but ignored. Support reps have been known to answer with a polite equivalent of "RTFM". I was given the "RTFM" response to the case I put in regarding tomcat leaking threads. They never resolved the case. Instead I ended up monitoring threads and restarting tomcat by hand. When we updated to a new version of Blackboard the problem magically went away. I'm not completely sure, but I think Blackboard never even realized that they were shipping a buggy version of Tomcat. They accidentally fixed it by shipping a newer version in a later release.

    They use incredibly inefficient stored procedures which can bring down an entire system

    Most of the complex processes, like deleting entire courses or students are carried out via stored procedures in the database (BB runs on SQL Server and Oracle). In SQL server, the stored procedures are extremely inefficient and can suck up so much memory that they bring the entire system to a grinding halt. I ran across this when trying to delete a bunch of very old courses in our system. In researching the problem I read that the use of cursors was a huge no-no in SQL server (but okay in Oracle!). The stored procedure that deletes courses was, of course, written using cursors. Not being a skilled DBA, I could not rewrite the SP myself, so instead I broke it up into parts and has a script run the individual parts on all of the courses I wanted to delete.

    Indeed, Tomcat is not to blame for speed problems. In fact current versions start up faster than Resin.

    On Windows, however, it does have the distinction of being the only app server incapable of undeploying wars through the expedient of merely deleting their directory. It runs into the file locking issues on Windows, which I do suppose is partly the blame of Windows, but I'd also point out that no other app servers have this problem.

    It also has classloader leaks that go back to the beginning of Tomcat, have never been fixed, and instead get blamed on bugs in the JVM (again it's a 50/50 thing, but Tomcat appears to be the only one incapable of working around it) .

    It is fast, but so much junk for all these reasons. For just plain servlets, Jetty is king now.
