One of the many messages left by leaders of the world on a silicon disk was this: "May the high courage and the technical genius which made this achievement possible be so used in the future that mankind will live in a universe in which peace, self expression, and the chance of a dangerous adventure are available to all."

See and Feel the iPhone
A recent patent backs up an idea I had about a haptic interface for the iPhone (it's not a new idea even for the iPhone):
The proposed solution is the adoption of "haptic" display technologies which allow for some tactile feedback from touch screen displays. Apple proposes including a grid of piezoelectronic actuators that can be activated on command. By fluctuating the frequency of these actuators, the user will "feel" different surfaces as their finger moves across it.
JRDF 0.5.5.5
It's been a long while between updates but it's finally here. There's been some general concessions made to long standing "features" in JRDF namely relational semantics and checked exceptions - both are gone. Yuan-Fang added merge-join support which improved join performance (by up to 8 times). There's Groovy support and a nasty memory leak fixed. It's in the usual place. The next version won't be so far away with some further SPARQL query improvements including perhaps some of the newly proposed features.
