E-book buyers will soon get settlement payments from Apple price-fixing case

Some buyers of e-books will begin to receive payments Tuesday as part of a settlement in a price-fixing case against Apple. People who purchased e-books between April 1, 2010, and May 21, 2012, will receive credits from e-book sellers, or will get a check if they opted out of receiving credits, according to Hagens Berman Sobol Shapiro, a consumer-rights class-action law firm involved in the lawsuit against Apple. As part of the Apple settlement of the case, e-book buyers will receive US$6.93 for every purchase that was a New York Times bestseller and $1.57 for every other e-book. The settlement covers e-books purchased from Apple as well as from other retailers, including Amazon.com and Barnes & Noble.To read this article in full or to leave a comment, please click here

Getting to the point of dual homing

I wonder how many times I’ve seen this sort of diagram across the many years I’ve been doing network design?

dual-homing

It’s usually held up as an example of how clever the engineer running the network is about resilience. “You see,” the diagram asserts, “I’m smart enough to purchase connectivity from two providers, rather than one.”

Can I point something out? Admittedly it might not be all that obvious from the diagram, but… Reality is just about as likely to squish your network connectivity like a bug no a windshield as it is any other network. Particularly if both of these connections are in the same regional area. The tricky part is knowing, of course, what a “regional area” might happen to mean for any particular provider.

The problem with this design is very basic, and tied to the concept of shared link risk groups. But let me start someplace a little simpler than that—with the basic, and important, point that putting fiber in the ground, and maintaining fiber that’s in the ground, is expensive. Unless you live in Greenland, fiber can be physically buried pretty easily (fiber in Greenland is generally buried with dynamite by a blasting crew, or Continue reading

Does your smartphone embarrass you?

Modern computer and internet technology is amazing, allowing us to do an incredible number of things that simple weren’t possible before, both individually and as part of larger organizations.But anyone who works with computer and mobile devices knows that everything isn’t perfect. Too often, computer systems are frustratingly hard to use. And now, the Nielsen Norman Group has identified a new problem stemming from sub-optimal user interfaces: computer-assisted embarrassment.Earlier this month, Susan Farrell described the phenomenon this way: “Smart devices have invaded our world and inserted themselves in almost every context of our existence. Their flaws and faulty interactions are no longer only theirs—they reflect badly on their users and embarrass them in front of others.”To read this article in full or to leave a comment, please click here

How big data is changing the game for backup and recovery

It's a well-known fact in the IT world: Change one part of the software stack, and there's a good chance you'll have to change another. For a shining example, look no further than big data.First, big data shook up the database arena, ushering in a new class of "scale out" technologies. That's the model exemplified by products like Hadoop, MongoDB, and Cassandra, where data is distributed across multiple commodity servers rather than packed into one massive one. The beauty there, of course, is the flexibility: To accommodate more petabytes, you just add another inexpensive machine or two rather than "scaling up" and paying big bucks for a bigger mammoth.To read this article in full or to leave a comment, please click here

Montreal wins Intelligent Community of the Year

COLUMBUS, Ohio -- Montreal, Quebec, was named “Intelligent Community of the Year” this week at the annual Intelligent Community Forum (ICF) Summit. In the face of economic decline and political scandals, Canada’s largest French-speaking city began its turnaround with a Smart City plan starting in 2011.The city, home to a 10th of Canada’s population, had endured trade losses, an eclipse of manufacturing, and years of separatist nostalgia. The new Montreal staked its future on a broader economic base of Information and Communications Technologies (ICT), aerospace, health sciences, and clean technologies. These sectors now field 6,250 companies with 10% of the region’s workforce.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Dude, where’s my phone? BYOD means enterprise security exposure

Sally called the security desk. She can’t find her personal smartphone. Maybe she lost it. Perhaps it fell behind her sofa. Maybe she left it at a restaurant last night. Perhaps someone stole it. Or maybe she put it down somewhere this morning.Whatever the case may be, it's not good—especially since Sally is a well-regarded and trusted mid-level manager with mobile access to many corporate applications and intranet sites that have a lot of sensitive and proprietary information.Now what?There are several types of dangers presented by a lost Bring Your Own Device (BYOD) smartphone or tablet, and many IT professionals and security specialists think only about some of them. They are all problematic. We’ll run through some of the scenarios in a moment, but first: Does your company have policies about lost personal devices?To read this article in full or to leave a comment, please click here

IDG Contributor Network: IoT decision making improved with impact-sourced human experts

Drowning in data is a real hazard with the Internet of Things (IoT). How should decisions be made with this flood of sensor data? A hybrid approach combining human intelligence and computing power works well. People are good at making decisions that require nuance and judgement, such as identifying hate speech in online postings. Computerized analytics is better at quickly processing large volumes of data. How do you combine the human thought-making process with the scalability of computing power? In machine learning, this is called supervised learning, where a computer program is taught to "mimic" the thought making-process of a human expert. To read this article in full or to leave a comment, please click here

Trying to track down a phisher

Tracking down the phisherImage by REUTERS/Danish IsmailSeveral weeks ago, a key member of the WatchGuard Technologies finance team was targeted by a spear phishing attempt. Spear phishing is a type of phishing attack in which the perpetrator customizes their attack to a particular individual or group of individuals. The attacker gathers information on the victim and then tailors the attack to be more likely to fool the target. The would-be attack arrived as an email appearing to come from the finance employee’s manager, requesting an urgent wire transfer.To read this article in full or to leave a comment, please click here
