IoT could help give your local area its own power grid

The Internet of Things is mostly about achieving greater scale, but in the case of an upcoming demonstration project, it will show how electrical grids can work at a smaller scale.The testbed announced Thursday by the Industrial Internet Consortium (IIC) will bring together software and other components for microgrids, which link together local, alternative sources of power and energy storage. Those sources, including rooftop solar panels and wind turbines, can keep providing power even if the main grid goes down.Most power grids were built for producing energy in one place and distributing it to users over a wide area. They’re not all equipped to manage or take advantage of small power sources out at the edge of the grid. The IIC, which is trying to get big industries and tech vendors on the same page about the Internet of Things, formed the testbed to promote work on IoT components for microgrids.To read this article in full or to leave a comment, please click here

What excites you about network virtualization?

Virtualization is actually nothing new to me, to be honest, because I’ve been dealing with multi-tenancy, which really in my mind, started on the WAN side where VPNs were really one of the first early versions of introducing multi-tenancy and segmentation of the network, and leveraging virtualization-type technology on hardware. It’s just fascinating to see how much that’s evolved and taken off in the compute world. Now, we’re coming back together full circle with SDN. The network is now playing catch-up with how much agility and flexibility virtualization has provided to the compute world. I believe I have been doing virtual networking for a number of years now, but obviously it’s morphed into something much more powerful Continue reading

The Upload: Your tech news briefing for Thursday, March 16

Facebook lawsuit says it stole data center designFacebook is being sued by a British engineering company that claims the social network stole its technique for building data centers and is encouraging others to do the same through the Open Compute Project. BladeRoom Group says it contacted Facebook in 2011 about using its method for constructing data centers in a modular fashion from pre-fabricated parts. It claims Facebook stole its ideas and used them to build part of a data center in Sweden, and is also sharing them via its OCP initiative.To read this article in full or to leave a comment, please click here

MLD Considered Harmful

Multicast Listener Discovery (MLD) protocol is well hidden deep in the bowels of IPv6 protocol stack and most of us tend to gloss over it when we discuss IPv6 neighbor discovery process… until MLD raises its ugly head to bite an unsuspecting network administrator.

The problems with MLD are not new (and I wrote exhaustively about them a while ago), but it’s always nice to see other people raise awareness of broken IPv6 features like Enno Rey and his security team did during the IPv6 Security Summit (part of Troopers 15 conference).

Facebook’s Like button can still easily be gamed

Facebook’s Like button is a pervasive feature of the Web, a way to gauge the popularity of a website or piece of content. But researchers have found it’s easy to inflate the numbers, undermining its value as an accurate measure of popularity.The problem of bogus Likes has been around for some time, and Facebook has released updates to its software over the last couple of years to cut down on fraudulent ones generated by spammers.But researchers with McGill University’s School of Computer Science in Montreal say the social networking company still hasn’t fixed several major problems with the feature. This week, they released a research paper outlining the problems, which they first told Facebook about in early 2013.To read this article in full or to leave a comment, please click here

FTC says it did not go easy on Google in search probe

The U.S. Federal Trade Commission said its decision not to prosecute Google over its search practices was in line with the recommendations of its staff.The statement issued Wednesday by FTC Chairwoman Edith Ramirez and Commissioners Julie Brill and Maureen Ohlhausen was in response to the leak of an internal document, which suggested that the agency’s staff had concluded that Google’s business tactics had caused “real harm to consumers and to innovation,” and had recommended a lawsuit against the company.The FTC’s decision on the search allegations was in accord with the recommendations of the FTC’s Bureau of Competition, Bureau of Economics, and Office of General Counsel, the three commissioners wrote, claiming that the document, which was inadvertently provided to The Wall Street Journal as part of a public records request, was only “a fraction” of the voluminous record and extensive internal analysis that was reviewed at the time.To read this article in full or to leave a comment, please click here

WhatsApp not as open as Messenger to outside developers

Facebook-owned WhatsApp, the popular mobile messaging and calling service, has no immediate plans to offer tools to outside developers to let them build services on top of it.Doing so could potentially introduce unwanted content into the app, slow it down, and disrupt the flow of one-to-one messages and interactions between its users, WhatsApp cofounder Brian Acton said Wednesday during a panel talk at Facebook’s F8 conference in San Francisco.Acton delivered his remarks after two developers from the audience asked when, if at all, WhatsApp would offer application programming interfaces or APIs to them.Acton was adamant. For the year, the company is focused on its voice calling service—which is available for Android now and coming to iOS soon—as well as its recently launched Web software, he said.To read this article in full or to leave a comment, please click here

Egyptian company says rogue Google SSL certificates were a mistake

An Egyptian company that created unauthorized digital certificates for several Google domains said Wednesday it made a mistake and acted quickly when the error became known.The SSL/TLS (Secure Sockets Layers/Transport Layer Security) certificates would have allowed MCS Holdings of Cairo to decrypt traffic sent by users on its network to Google, a major privacy concern. Google said it doesn’t believe the certificates were misused.But MCS shouldn’t have been able to create digital certificates for Google properties in the first place. It appears MCS and a Certificate Authority (CA) in China both made mistakes, which highlight ongoing problems in the way digital certificates are issued.To read this article in full or to leave a comment, please click here

How Messenger chats factor into what you see in Facebook news feed

Havent seen many posts from some friends lately on Facebook? Perhaps you need to reach out directly to them.How often you chat with someone using Facebooks Messenger app is a signal the company uses to determine how to place posts in your feed. If you havent chatted with someone in a while on Messenger, and then you start chatting again, posts from that person might appear higher in your news feed.That was one piece of information shared by Facebook engineers during a session Wednesday during the companys F8 conference in San Francisco.The algorithm Facebook uses to rank posts in peoples news feeds is a complicated one, and it’s always in flux, but the session, titled “How News Feed Works,” shed light on it.To read this article in full or to leave a comment, please click here
