The streetlights are topped by a solar panel crest, and have "kinetic tiles" on the ground below them. These panels reportedly can generate 4 to 8 watts from people walking on them, depending on the pressure of the step. The renewable energy is then collected by a battery for use at night. The solar-plus-kinetic energy design is useful on those rare Vegas days without too much sun -- as long as there is still plenty of foot traffic.
A former Oracle Java evangelist, however, sees the open source move as watered down. "Sun didn't open-source Java per se," says Reza Rahman, who has led a recent protest against Oracle's handling of enterprise Java. "What they did was to open-source the JDK under a modified GPL license. In particular, the Java SE and Java EE TCKs [Technology Compatibility Kits] remain closed source."
Rahman adds that "Without open-sourcing the JDK, I don't think Java would be where it is today."
This new paper offers "a comprehensive picture of the current knowledge of M-dwarf planet occurrence and habitability," pointing out that most of these stars are apparently orbited by planets packed closely together, with "a paucity of Jupiter-mass planets and the presence of multiple rocky planets." And more importantly, roughly a third of those rocky planets are orbiting in a "habitable zone" -- far enough away from their stars to support liquid water.
The researchers add that "at this stage, this hypothesis needs to be confirmed with further work," and Seth Shostak, a senior astronomer at SETI, tells Space.com that "If I were a betting guy, I'd bet this is an artifact of the way they processed their data."
"Demand is off the charts!" the app informed its users, adding "Fares have increased to get more Ubers on the road." Uber soon tweeted that they'd deactivated their surge pricing algorithm for the affected area in Chelsea, "but passengers in other areas of Manhattan said they were still being charged higher than normal fares." One of the affected passengers was Michael Cohen, who is Donald Trump's lawyer, who tweeted that Uber was "taking total advantage of chaos and surcharging passengers 1.4 to 1.8 times." And another Uber user tweeted "I'm disgusted. People are trying to get home safe. Shame on you #DeleteApp."
