Finite State Automata in Lucene

· Java Zone

Discover how AppDynamics steps in to upgrade your performance game and prevent your enterprise from these top 10 Java performance problems, brought to you in partnership with AppDynamics.

Lucene Revolution 2012 is now done, and the talk Robert and I gave went well! We showed how we are using automata (FSAs and FSTs) to make great improvements throughout Lucene.

You can view the slides here.

This was the first time I used Google Docs exclusively for a talk, and I was impressed! The real-time collaboration was awesome: we each could see the edits the other was doing, live. You never have to "save" your document: instead, every time you make a change, the document is saved to a new revision and you can then use infinite undo, or step back through all revisions, to go back.

Finally, Google Docs covers the whole life-cycle of your talk: editing/iterating, presenting (it presents in full-screen just fine, but does require an internet connection; I exported to PDF ahead of time as a backup) and, finally, sharing with the rest of the world!

The Java Zone is brought to you in partnership with AppDynamics. AppDynamics helps you gain the fundamentals behind application performance, and implement best practices so you can proactively analyze and act on performance problems as they arise, and more specifically with your Java applications.
