Samsung Galaxy Note 7

Samsung's aggressive battery design led to the Galaxy Note 7 explosions

As the report points out, compressing the battery would force the positive and negative layers to squeeze together. Samsung itself said that it might have been too aggressive with the design. In addition, there is a normal amount of swelling that takes place. Some of it comes from the pressure on the battery created through pushing on the back cover (for example, by putting the phone in one's back pocket and then sitting on a chair). 
In order to make the phone thin, the batteries were designed to be carry as much capacity as possible, while keeping to a svelte footprint. The report stated that if the phablet had not been recalled, the body of Galaxy Note 7 units throughout the world would probably have separated.
Samsung was taking a risk by shipping a battery that left very little wiggle room for problems. And yes, this should have been spotted in tests. However, Samsung broke protocol by handling the testing itself. 
"The design and validation process for a new product is challenging for everyone. In this case, Samsung took a deliberate step towards danger, and their existing test infrastructure and design validation process failed them. They shipped a dangerous product. That this is possible at one of the top consumer electronic companies in the world is humbling -- and demonstrates the need for better tools. Instrumental is building them."-Instrumental
Samsung did shoot itself in the foot. By one calculation, the company will tally more than $5 billion in lost revenue and other costs associated with the recall of the Galaxy Note 7.

According to a new report, Samsung's aggressive design for the battery employed by the Galaxy Note 7might have been the culprit behind the multiple explosions that led the company to pull the phablet from the market. The way the cell was designed, a pair of polymer layers drenched in electrolytes was used to separate a positive layer made of lithium cobalt oxide, and a negative layer made of graphite. Should those two layers meet, the electrolytes would heat up causing an explosion.

Kumamoto quakes caused ¥3.8 trillion damage, official estimate shows

Powerful earthquakes that hit Kumamoto Prefecture in April caused damage worth ¥3.8 trillion, the local government has confirmed in its first estimate of the economic impact on the prefecture. 

Homes suffered the worst damage at about ¥2 trillion, with approximately 170,000 houses affected including around 8,000 that were completely destroyed.

A magnitude-6.5 quake hit the prefecture on April 14, followed by a 7.3-magnitude quake two days later.

Damage to the business sector, including factories and hotels, was estimated at ¥820 billion and damage to roads, bridges and other public infrastructure at ¥268.5 billion, the government said Wednesday.

A total of ¥93.6 billion in damage was logged for cultural property, ¥148.7 billion for the agricultural sector and ¥90 billion for waste processing facilities.

In May, the central government estimated the damage in Kumamoto at around ¥1.8 trillion to ¥3.8 trillion.

The Hokkaido government said the same day that four powerful typhoons and an extratropical depression downgraded from a typhoon that hit the island in August caused ¥278.6 billion of damage, with flood damage totaling ¥66.1 billion.

Damage to the agricultural sector reached ¥54.2 billion, with 38,927 square meters of farmland used for growing onions and potatoes spoiled, while damage to the fisheries industry was estimated at ¥7.4 billion and the forestry sector at ¥6 billion.

The local government plans to compile its largest supplementary budget of ¥65 billion to rebuild infrastructure and other facilities

VR 虛擬實境

Mark Zuckerberg shared this video of his 'crazy virtual reality' where 'you can experience anything'

There's no question the next big thing that's coming to entertain you is virtual reality.

But when you see people with those bizarre looking masks on, VR looks like it's an isolating experience: like you'll be hanging out with imaginary friends in your own little world all alone:

Facebook founder and CEO Mark Zuckerberg hoped to dispel that lonely notion during a presentation in California on Thursday. That's when he showed off the latest version of Facebook's next generation VR headset, Oculus Rift.

The presentation was all about how you can use Rift to hang out with real, but far away, people exploring fantasy VR worlds together. Or, if you prefer, you can play card games with them, or have work meetings.

When you enter the VR world, those real people look like cartoons (at least for now), but if you can overlook that, you can see how Facebook has focused on things like facial expressions and gestures.
