On that note, any other HNers planning to be at the demo in Cambridge on Tuesday? http://cyber.law.harvard.edu/events/2009/04/wolfram It seems like it's worth going to - and it's directly related to something I'm doing at work (inference over topic maps).

I'd like to, but it's full! I'll be watching the webcast ...

this sounds like something that spans the (rather wide) gap between google and aws + public data sets. I wonder how far you can go in terms of combining data/hacking on it?

For example they mention real-time financial data. So can I write something that would connect online discussion/activity to stock movements?

A platform for doing large scale, real-time data analysis in a rich descriptive language without doing any of the dirty work would be quite something.

Didn't knew that something like that could be coded in Mathematica.

Indeed, Wolfram himself once solved a Google puzzle (to encourage job applicants) using Mathematica. It was, what's the pattern here, and what's the next row?

1 11 21 1211 111221 312211

Google is smart enough for this:

I always find these puzzles odd

Why can't this row be valid?

1 11 21 1211 111221 312211 1 11 21 1211 111221 312211 1 11 21 1211 111221 312211 ....

Why does it have to be 13112221? Is it just a most close answer according to average math pupil's knowledge model psychologically?

But why Google when you can OEIS? http://www.research.att.com/~njas/sequences/
