How Shared Spectrum Can Improve In-Building Cellular

You’ve been there before: You popped into a store and wanted to look something up on your smartphone while waiting in line. However, the cell signal shows just one lousy bar. You consider logging on to Wi-Fi but there are multiple inconvenient steps that aren’t worth the hassle while you’re waiting in line. Nope, you’ll just wait to go back outside and go somewhere else next time.

Why can’t Wi-Fi be as simple as pulling the phone out of your pocket, like cellular? Or, better yet, why can’t cellular just be everywhere Wi-Fi is, including deep inside buildings? The answer lies in a little-known fact about cellular: Your phone company owns the right to use the cellular airwaves everywhere, even if, as in the example above, it’s not actually using them where you happen to be. 

You may think that the store, realizing that you may never come back, would be willing to spend a little cash for better cell service, but it can’t. The store doesn’t own the right to use the airwaves inside its walls, thus it must work with each phone company individually to convince them to install a Continue reading

Should Technology Mirror Business?

The essence of SDN is to create a software model of the current data network business. This quantitative model is based on volumes of data: what ‘bandwidth’ resources do I have (i.e. supply), and how can I give different quantities of this ‘bandwidth’ to different users and uses (i.e. demand)? -via circleid

I’ve been in information technology since the early 1990’s, and it’s always been like this: business tells IT what to do, and IT does it. In other words, we make technology mirror business. Which is a fine formula for success, so long as you think business is the engine of innovation. The problem is innovation doesn’t come from one department or place. In fact, innovation most often comes from the intersection of two or more things. Think about it.

When did cars first start being innovative? When they combined the technology that existed in the latest horse drawn carriages with the latest in industrial technology, including internal combustion engines and assembly line production. All three of these came from someplace else—many people don’t know the idea of interchangeable parts came out of the firearms world, rather than the automotive industry. When did innovation come into the Continue reading

Worth Watching: The Economics of the Internet

Old economics explains the new economy well. When we buy something, we spend time and money searching for it, comparing it with other products, negotiating a price, and ensuring that we get what we paid for. This is what economists call ‘transaction costs.’ The internet dramatically reduces these costs, making it cheaper for people, businesses and governments to do business. -via the World Bank

Xen’s latest hypervisor updates are missing some security patches

The Xen Project released new versions of its virtual machine hypervisor, but forgot to fully include two security patches that had been previously made available.The Xen hypervisor is widely used by cloud computing providers and virtual private server hosting companies.Xen 4.6.1, released Monday, is flagged as a maintenance release, the kind that are put out roughly every four months and are supposed to include all bug and security patches released in the meantime."Due to two oversights the fixes for both XSA-155 and XSA-162 have only been partially applied to this release," the Xen Project noted in a blog post. The same is true for Xen 4.4.4, the maintenance release for the 4.4 branch that was released on Jan. 28, the Project said.To read this article in full or to leave a comment, please click here

Should you worry about the Internet of Hackable Things?

If 2015 was the year of the Internet of Things, 2016 could be the year of the hacked Internet of Things. That could mean a lot of headaches for CIOs, whether they're fans of these new devices themselves or will be dealing with employees connecting them at work and managing the potential security exposure that brings. "The issue to date is that devices are vulnerable just by the fact that they exist and can connect to the Internet," says Jerry Irvine, member of the U.S. Chamber of Commerce’s Cybersecurity Leadership Council and CIO of Prescient Solutions. "Anybody can get to a device if you don't secure them properly." To read this article in full or to leave a comment, please click here

How to prevent shadow IT

Stopping the armchair IT folksImage by Mette1977 What do complex IT policies, outdated software and lack of IT-supported services have in common?

We’ve always been at war with Eastasia

Our media is surprisingly Orwellian, and it's not always due to government control. People practice "doublethink" at their own volition, without a Thought Police. Social media (Twitter, Facebook) are instituting their own private Thought Police. Online journalism now means that the press is free to edit old articles, to change past reporting to conform to new political realities.

Consider the example in the book 1984 regarding the ongoing war between the three superstates of Oceania, Eurasia, and Eastasia (representing English, Russian, and Chinese empires respectively).

At the start of the book, Oceania is at war with Eurasia. They have always been at war with Eurasia. That's the political consensus, and all historic documents agree. However, Winston Smith (the protagonist) remembers a time five years ago when Oceania was instead at war with Eastasia. Winston Smith struggles with philosophical idea of "truth". Which is more true, what everyone knows and what's in the newspapers, or the memories within his head?

Then Ocean's allegiance switched back again. On the sixth day of Hate Week, as crowds gathered to denounce Eurasia, the Party switched enemies to Eastasia. In a particularly rousing speech against their enemy, the speaker was handed a slip of paper, Continue reading
