Aug 31New UM Sites Launch

Today we launched the new set of Universal Mind websites:

www.universalmind.com

and

blog.universalmind.com

Adam has gone into a great deal about the technical specifics of the new www.universalmind.com, so I will go into the technical specifics of blog.universalmind.com, since I wrote it (skin by Nahuel and Laura).

Previously, the UM Blog Aggregator had been an experiment in combining Hibernate and ColdFusion with Mach-II. This, over time, proved to be a bit unstable, to say the least. About a month ago, I took on the initiative to re-write the entire aggregator using Java. Under the hood, we're still using Hibernate, but we're also using Spring and SpringMVC to manage the transactions and Hibernate sessions a bit better. One thing you'll probably not notice, but is the coolest to me, is that the post search is now powered by Hibernate Search. What does this mean? Well, every time a new post is aggregated and persisted, Hibernate transparently indexes the object and makes it searchable. It's powerful stuff.

Anyway, I hope you enjoy the site and please give us some feedback.

Andy, you make it sounds like Mach-II was causing the unstable-ness in your architecture. Please elaborate.

Sorry, that was not the intent. The actual problem, I believe, was how sessions and transactions were being handled. Essentially, we were getting stack overflows every few months. SpringMVC handles all that stuff for us and is better suited. Mach-II is not the issue at all.

Can you elaborate about 'getting stack overflows every few months'?

I mean, how you spotted it, what you did to fix it straight away and what you did in the longer term (before your rewrite)

Thanks

@Matt - make sure you clear cache.

@Mark - It was fairly easy to spot... it would start throwing HTTP 500 errors and dumping stacktraces while processing CFOUTPUT. There was no long-term fix, except for the rewrite, as I never really had time to devote a lot of attention to it.
