Google Open Sources Wave Protocol Implementation 183

eldavojohn writes "Certainly one of the most important steps in adopting a protocol is a working open source example of it. Well, google has open sourced an implementation of the wave protocol for those of you curious about Google's new collaboration and conversation platform. It's been reviewed, skewered and called 'Anti-Web' but now's your chance to see a Java implementation of it. The article lists it as still rapidly evolving so it might not be prudent to buy into it yet. Any thumbs up or thumbs down from actual users of the new protocol?"

Finally, a True Green Laser 274

dusty writes "Remember those green lasers from Star Wars? Turns out that faking green lasers has been easy for years, but making true green laser diodes has been the stuff of science fiction. Until recently, that is. Now researchers from Japan have created the world's first true green laser diode. Until now, only red and blue laser diodes were available, and now with the addition of green, new TVs and projectors that are more efficient can be produced. And if you were wondering how green lasers pointers are already produced, it is a hack that involved doubling the frequency of an infrared laser. The new true green laser diodes have much higher efficiency than the current 6%, leading many to expect big time laser display breakthroughs in the near future. Ars Technica has a well-written article on this breakthrough."

Submission + - Be the first to photograph an aurigid meteor (seti.org)

rmelton writes: "As previously mentioned on http://science.slashdot.org/article.pl?sid=07/08/0 8/1830257 The long period comet
"Kiess" laid down debris that will create an unusual meteor shower Sept 1st visible from the western US. These
meteors have never been photographed. Using a ditital camera with long exposure you should be able to
capture images of these meteors. Seti is looking for a picture of the brightest of these.
Chances are that an amateur will catch the brightest Aurigid out there. Even simple cameras can
provide information about how the meteoroids break apart. The color separation can be used as a
simple spectrometer to indicate the meteor composition.
see http://seti.org/news/features/2000-year-old-meteor s-to-rain-down.php or http://aurigid.seti.org/ for more."
