Ecuador earthquake: At least 413 people confirmed dead
link

At least 413 people are now known to have died in the earthquake that struck Ecuador, the country’s government says.
The 7.8-magnitude quake struck Ecuador’s Pacific coast on Saturday, and the search for survivors continues.
The cost of rebuilding is likely to be in the billions of dollars, President Rafael Correa said during a visit to the worst-affected region.
He said it was the biggest tragedy to hit Ecuador in the past seven decades. Some 2,500 people were injured.

YouTube live-streams in virtual reality and adds 3D sound
link

YouTube is introducing live-streamed 360-degree videos on its service.
YouTube made it possible to play interactive 360-degree videos on its site just over a year ago.
If viewed on a laptop, viewers can use a mouse to adjust their perspective. But if watched on a smartphone or VR headset, the experience becomes more immersive, as changes in viewpoint correspond to the movements of the device being used.
Until now, clips had to be uploaded to YouTube in their entirety and processed before they could be played back.
“When you use your eyes, you are looking with a field-of-view of at best 120 to 180-degrees, depending on who you are,” said Dr Gavin Kearney, an audio researcher at the University of York.
“But sounds are omni-directional - they are all around us.
“So, binaural audio is important from the aspect of VR because it lends itself to the realism, the immersion, of the experience.
“If you have good visuals but poor audio cues, it breaks the illusion of the reality you are trying to create. But with good binaural audio, it’s much more plausible.”
Headphones must be worn for the effect to be created, and it will only work via YouTube’s Android app on pre-recorded clips at launch.

Google wins copyright battle over books
link

The US Supreme Court has ruled in favour of Google in its 11-year legal battle with an authors group.
The Court said it would not hear an appeal from the Authors Guild, which claimed Google breached copyright laws by scanning books without permission.
The technology giant began the process in 2004, so it could include extracts in a searchable database, and it was sued by the Authors Guild in 2005.
The Supreme Court’s judgement is the final ruling on the matter.

My comment：In the digit age，the share of information is common and needed， so the Google book is a good project if it dont infringe the authors’ copyright。
