How much can a fiber carry? Facebook and Nokia are pushing it

Facebook and Nokia have found a way to push a lot more data through a submarine cable across the Atlantic, which could help the social network keep up with the growth of video and virtual reality.On a 5,500-kilometer (3,400-mile) cable between Ireland and New York, the companies tested a new technique developed at Nokia Bell Labs for increasing the efficiency of fiber-optic cables. They say it comes close to the absolute limit for sending bits over a fiber.Facebook CEO Mark Zuckerberg has said VR is the future of social media. If it is, then the networks that link consumers and data centers will have more data than ever to carry. Higher resolution video also is increasing the burden on networks. For example, Netflix recommends subscribers have at least a 5Mbps broadband connection to stream HD video and 25Mbps for Ultra HD (4K) streams.To read this article in full or to leave a comment, please click here

What it takes to become an IT security engineer

When Scott Copeland got his associate degree in network administration back in 2004, the community college he attended didn’t offer IT security courses, “but it gave me the foundation to learn more about network security,” he says. His determination and thirst for learning led him to his current job as an IT security engineer at FedEx Services in Memphis, Tenn. download What it takes to become an IT security engineer | PDF download CSO Online Getting started After being laid off in 2008 from his first IT job in tech support and systems administration, friends encouraged Copeland to use his networking talents to get a certification that would boost his career. He studied for three months and earned his Cisco Certified Network Associate (CCNA) certification in routing and switching. “CCNA was the biggest helper [for my security career path],” says Copeland. “It’s one of the hardest network certifications in the industry.” Also, he notes, “because it ties networking for firewalls and VPN, it has security components to it.” He also scoured daily posts on Reddit, the news aggregation and discussion website, to learn as much as he could about network and IT security, and to keep up with Continue reading

Microsoft completes Windows 10 customized for China’s government

Microsoft has wrapped up work on a version of Windows 10 for China's government and state-owned businesses, and is ready to begin selling the software, a state-run newspaper said today."We have worked extensively to make it secure and controllable. We are now ready to serve the market," Alain Crozier, the CEO of Microsoft's Greater China operation, told China Daily.The modified Windows 10 was the result of a December 2015 deal with China Electronics Technology Group (CETC), a state-backed defense contractor. Microsoft and CETC formed a joint venture, C&M Information Technologies, to license the operating system to government agencies and some state-owned enterprises, including ones that control energy, telecommunications and transportation.To read this article in full or to leave a comment, please click here

Peelytics turns peeing into a way to promote products

Not many companies would want you to pee on their product, but one at Cebit positively encourages it.Peelytics of Heidelberg, Germany, has developed a Bluetooth beacon that detects when someone is urinating on it, and for how long. If that person has a hand free to wake up their smartphone, they can "claim" that micturition as their own using the Peelytics app, and perhaps win a prize if they peed for longest.It's all a game designed to encourage people to improve their aim (keeping restrooms cleaner) and to pay attention to promotional messages while in toilets in bars and clubs -- areas that marketers have already identified as prime placements for advertising.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Acoustic attack lets hackers control smartphone sensor

A newfound vulnerability in smartphones could let hackers remotely control the devices.With the acoustic injection attack, “attackers that deliver high intensity acoustic interference in close proximity” can interfere with a device accelerometer and get the sensor to send “attacker–chosen” data to the smartphone’s processor, say researchers from the University of Michigan and University of South Carolina in a paper.Accelerometers measure changes of speed in a device, and they are used industrially to sense vibration for machinery health. In a smartphone, the accelerometer sensor can be used to detect screen orientation, for example.To read this article in full or to leave a comment, please click here

Upstart Switch Chip Maker Tears Up The Ethernet Roadmap

Ethernet switching has its own kinds of Moore’s Law barriers. The transition from 10 Gb/sec to 100 Gb/sec devices over the past decade has been anything but smooth, and a lot of compromises had to be made to even get to the interim – and unusual – 40 Gb/sec stepping stone towards the 100 Gb/sec devices that are ramping today in the datacenter.

While 10 Gb/sec Ethernet switching is fine for a certain class of enterprise applications that are not bandwidth hungry, for the hyperscalers and cloud builders, 100 Gb/sec is nowhere near enough bandwidth, and 200 Gb/sec, which is …

Why your cloud strategy should include multiple vendors

For decades, enterprise computing environments have been composed of servers, storage and networking equipment developed by different vendors. Those choices often hinged on the best products to power applications and data -- as well as the enticing volume discounts tossed into enterprise agreements. A similar scenario is playing out in cloud computing infrastructure, where CIOs are grappling with how to best architect systems for multi-vendor, hybrid cloud strategies.A telling exchange on cloud vendors occurred during the Wall Street Journal’s CIO Network event last month when an audience member shared his perspective on the challenges of choosing between different cloud vendors with Adrian Cockcroft, vice president of cloud architecture strategy for Amazon Web Services (AWS), who was speaking on stage.To read this article in full or to leave a comment, please click here
