ETech Day Three – Elephants, Fire Eagles and Disaster Tech

I got a bit wrapped up trying to get a side project finished up yesterday, so I’ll just skip to day three of ETech. The morning opening speakers were better that Day Two, although the session thus far have been a bit below Day Two’s. We kicked off the morning with an abbreviated talk by John McCarthy (father of LISP) on a new language he’s working for several years called Elephant. The elephant name coming from the fact it never forgets, and the broad concept of a semantic programming language that can create structured relationships from natural language. Unfortunately he ran out of time before he really got into the guts of it, but there were some fascinating concepts with how natural language can be leveraged in a structured way to do computation. Definitely something worth looking into more, and it reminded me a lot of our thoughts about a context driven architecture and natural language for data. Although we were looking to turn quantitative data into natural language versus turning natural language into data.

Following McCarthy’s talk there were some interesting bits on open source personal robots, then an informal launch on Yahoo’s Fire Eagle. Fire Eagle has taken some flack in the blogs for having minimal or “zero” functionality. I think this misses the point of what Fire Eagle is intended to do. My impression was that Fire Eagle is not meant to be a stand alone consumer application but a straight forward tool that does a simple thing very well. That simple thing being a platform for sharing your location online. The functionality folks are clamoring for is left to the users and developers and I think there are good number of fun possibilities here. For instance with GeoCommons we have big pile o’ data and would be very useful to personalize that data delivery to a users location, or have user have the ability to comment on that data from their location and have that comment geo-located. This creates a dependency on clever users, but form what I’ve heard floating around ETech there seem to be a good number of clever ideas floating around.

The last session of the day I attended was Mikel and Jesse’s presentation on “Disaster Tech”. I’d seen Mikel’s presentation at the State of the Map conference on open source disaster technology, and it was cool to see how the project has evolved. The whole topic is something close to us, especially getting up close doing disaster response after the London Bombings and Hurricane Katrina. The presentation has some great examples of Open Street Maps, Twitter and Google Maps being used in creative ways during disasters. Mikel gave a nice example of using the USGS GeoRSS earthquake feed, the EU lightweight tsunami propagation model and a feed to republish the resulting polygons as GeoRSS. With this approach they can churn out a polygon warning area in under a minute. A similar concept is seen at the United Nations – GDAC application.

All great stuff for ad hoc implementation that is cost effective and not over engineered. Lots of good discussion of how take the information produced by technology and effectively transmit it to non-technical or completely unconnected people. Also Jesse and Mikel had a nice bit at the end of the presentation on anti-patterns – i.e. what happens when you don’t have a champion for the technology to create repeatable and successful implementations. Specifically the case of the search for Steve Fosset where the crowd sourced help to find him actually slowed down the search and rescue teams having to deal with all the input. Resulting in the emergence of champions like InternetSAR that creates a structure that could be replicated and effective for search and rescue. Lots of good thought on an important topic
