An Experiment In BlackBerry Development 207

ballwall writes "We've all read the stories about how lucrative selling apps on the iPhone can be (or not), but what about other platforms? BlackBerry accounts for twice as many handsets shipped as Apple, according to Gartner, so I decided to find out. I wrote about my experiences developing my first BlackBerry application including sales, platform issues, and a bunch of other things I thought new mobile developers might want to know about."

Protecting the Apollo Landing Sites From Later Landings 339

Posted by timothy on Friday June 05, 2009 @02:46AM from the everyone-must-have-a-hobby dept.

R3d M3rcury writes "The Lunar X-Prize is a contest offering $20 million to the first private organization to land and maneuver a robotic rover on the moon. There is also a $1 million bonus to anyone who can get a picture of a man-made object on the moon. But one archeologist believes that 'The sites of early lunar landings are of unparalleled significance in the history of humanity, and extraordinary caution should be taken to protect them.' He's concerned that we may end up with rover tracks destroying historic artifacts, such as Neil Armstrong's first bootprint, or that a mistake could send a rocket slamming into a landing site. He calls on the organizers to ban any contestant from landing within 100KM of a prior moon landing site. Now he seems to think this just means Apollo. What about the Luna and Surveyor landers? What about the Lunokhod rovers? Are they fair game?"

If you could replicate any given item of value a la Star Trek, the basic assumption that all Western economies are built on (there exist products that are not plentiful in nature, and value can be created by making these products available in exchange for other products which are not plentiful in nature, viz. cash) would evaporate overnight.

I think they'll still exist products "which are not plentiful in nature" if replicators are ever invented.

From my understanding anyway, a replicator won't be able to create things out of thin air, but will requires raw materials to put together the new (replicated) object (not plentiful in nature). Also it'll also require power to run while replicating (another non-plentiful thing in nature)
