Facebook Inflated Video Viewing Stats For Two Years

Slashdot - Fri, 23/09/2016 - 2:40pm
Facebook has admitted inflating the average time people spend watching videos for two years by failing to count people who watched for less than three seconds. CNET reports: The metric was artificially inflated because it only counted videos as viewed if they had been seen for three or more seconds, not taking into account shorter views, the company revealed several weeks ago in a post on its advertiser help center web page. Facebook has been putting a greater emphasis on video in recent years, particularly live video. In March, Facebook began giving anyone with a phone and internet connection an easy way to broadcast live video to the 1.7 billion people who use its service every day.

Oxygen levels were key to early animal evolution, strongest evidence now shows

Science Daily - Fri, 23/09/2016 - 2:07pm
It has long puzzled scientists why, after 3 billion years of nothing more complex than algae, complex animals suddenly started to appear on Earth. Now, a team of researchers has put forward some of the strongest evidence yet to support the hypothesis that high levels of oxygen in the oceans were crucial for the emergence of skeletal animals 550 million years ago.

How to power up graphene implants without frying cells

Science Daily - Fri, 23/09/2016 - 2:05pm
In the future, our health may be monitored and maintained by tiny sensors and drug dispensers, deployed within the body and made from graphene -- one of the strongest, lightest materials in the world. Graphene is composed of a single sheet of carbon atoms, linked together like razor-thin chicken wire, and its properties may be tuned in countless ways, making it a versatile material for tiny, next-generation implants.

Akamai Kicked Journalist Brian Krebs' Site Off Its Servers After He Was Hit By a Record Cyberattack

Slashdot - Fri, 23/09/2016 - 2:00pm
An anonymous reader writes:Cloud hosting giant Akamai Technologies has dumped journalist Brian Krebs from its servers after his website came under a "record" cyberattack. "It's looking likely that KrebsOnSecurity will be offline for a while," Krebs tweeted Thursday. "Akamai's kicking me off their network tonight." Since Tuesday, Krebs' site has been under sustained distributed denial-of-service (DDoS), a crude method of flooding a website with traffic in order to deny legitimate users from being able to access it. The assault has flooded Krebs' site with more than 620 Gbps per second of traffic -- nearly double what Akamai has seen in the past.

Jawbone Fails To Pay Key Business Partners and Has Almost No Inventory In Stock: Sources

Slashdot - Fri, 23/09/2016 - 1:00pm
BarbaraHudson writes: The battle between Fitbit and Jawbone may be coming to an end. Business Insider is reporting that wearable fitness maker Jawbone is facing some serious financial problems as the company has almost no inventory in stock and is running out of options to generate revenue. If you click on any of the products for sale on their site, it will say that they're all sold out. Business Insider reports: "Jawbone's Facebook page is littered with complaints from customers saying they have been unable to get in touch with a customer service representative to help with defective products. The Jawbone Facebook account has been responding to these issues, blaming a backup of complaints for the delays. A Jawbone spokesperson said the complaints were because of Jawbone's customer service restructuring. Another person close to Jawbone told Business Insider that there is almost no inventory left and the company is running out of options to generate revenue. The speculation among some Jawbone employees now is that the company might sell to a private equity firm if it can't raise more money, the person close to the company said. Jawbone also declined to explain why its inventory has sold out. A spokesperson said, 'they have sold through what they have to sell.' The company said it was not because it couldn't pay vendors though. It would not provide any estimate on when products would be available for sale on its site again, but did say it planned to make more products." The report says that, according to an internal NexRep email, the company cut ties with the customer service agency NexRep earlier this month after Jawbone failed to make payments. "The email, written to NexRep employees by a NexRep executive, claims that Jawbone is 'struggling financially' and that it couldn't pay NexRep for its services," reports Business Insider. "It also says Jawbone is 'fighting hard' to raise more funding. 'Jawbone is not able to pay us for past services, and their ability to pay us in the future is uncertain at this point,' the NexRep email reads." This resulted in "many staffers being laid off."
