This youtube video shows the possibility of using Emacs with a "continuous" compilation feature turned on... it is horribly slow, since the guys who made it do not talk, but only type :-( so feel free to skip all the way to 4':30'' (out of 5') to see the interesting part. Sounds good to me...

I just posted on-line a Demo (work in progress) of a tool for Schema Evolution support i designed and implemented during my stay in UCLA under the guidance of Carlo Zaniolo and with the collaboration of Hyun J. Moon.

 Feel free to test it, criticize it, and report me feedback of any kind: Prism a tool for schema evolution (http://yellowstone.cs.ucla.edu/schema-evolution/index.php/PrismDemo)

 A Video of a typical interaction with the interface is available at: Prism a tool for schema evolution (http://yellowstone.cs.ucla.edu/schema-evolution/documents/Prism-Demo.mov)

 Let me know your opinions ...

I found i nice repository of User Defined Functions for MySQL. In particular there are simple extensions of the few statistical functions offered by MySQL.

In Politecnico di Milano, together with Giorgio Orsi i supervised two students Fulvio Crivellaro and Gabriele Genovese that port Jena to run on J2ME.

The results has been amazing, the API we developed is even faster than the original Jena within 4000 tuples (more than enough on Mobile Systems).

The library available for download at: http://poseidon.elet.polimi.it/ca/?page_id=59

It has also been released in the jena-contrib package, see: http://jena.sourceforge.net/contrib/contributions.html

Please contact me for questions or suggestions.
