IDG Contributor Network: Light network via air hits 224 Gbps

How about this for an idea: run broadband to the home via wires and then spurt the last few meters via airwaves.Neat idea, right? You get the benefits of bulk speed through wire and the portability of a consumer device through airwaves.And, if you think you've heard the idea before, you're not mistaken. It's called wired Internet service coupled with Wi-Fi. Been there, done that.Still, it's a good idea.Well, here's a novel twist on that theme — run broadband via fiber to the home and then send the last couple of yards via airwaves. But, in this case, don't translate to Wi-Fi for the last few yards. Use the light you've already got in the fiber and just extend it outwards from the wire to the devices.To read this article in full or to leave a comment, please click here

Presentations in Markdown Using Deckset

Over the past couple of years, Markdown has become an important part of my computing landscape. I’ve transitioned almost all of my text-based content creation, including this blog, over to Markdown. I’d also been looking for ways that I might be able to extend my use of Markdown into creating presentations as well, but hadn’t—until recently—found a tool that fit into my workflow. Then I started using Deckset.

The idea behind Deckset is not unique; there are other projects out there that do the same sort of thing. (Remarkjs is one example that I’ve also used; more on that in a moment.) You create your presentation in Markdown, using headings, bulleted lists, numbered lists, etc. Markdown is just plain text, so you can use any plain text editing tool you like for this part. Deckset itself is OS X-specific, but the content remains platform- and application-independent (use any text editing tool on any platform you like).

Because Markdown isn’t natively suited to creating presentations, Deckset—along with all the other solutions I tried—have to add some “extensions” to Markdown. For example, in Deckset’s case:

• You’ll use three hyphens (---) to denote the start of a new slide.
• Continue reading

Samsung smart TVs don’t encrypt the voice data they collect

Samsung does not encrypt voice recordings that are collected and transmitted by its smart TVs to a third party service, even though the company has claimed that it uses encryption to secure consumers’ personal information.A week ago, the revelation that Samsung collects words spoken by consumers when they use the voice recognition feature in their smart TVs enraged privacy advocates, since according to Samsung’s own privacy policy those words can in some cases include personal or sensitive information. The incident even drew comparisons to Big Brother behavior from George Orwell’s dystopian novel 1984.To read this article in full or to leave a comment, please click here

Why Apple isn’t likely to compete with Tesla

With nearly $200 billion in cash on its balance sheet, Apple can do almost anything – including buying Tesla at a relatively affordable market cap of just $25 billion. But the swashbuckling Elon Musk's electric vehicle and reusable SpaceX rocket depend on technological breakthroughs and big capital investments over long periods before seeing a payback. That just isn't how Apple rolls.The abbreviation for research and development at Apple should be r&D (small r, big D) because the company keeps the riskier research small and invests big in development. The battery breakthroughs needed for mainstream electric vehicles are still on the horizon, and Apple doesn't have the cultural disposition to put its battery patents in the public domain to stimulate innovation as Tesla did. Nor does Apple have the stomach to make big investments to achieve speculative economies of scale needed for a mass-produced electric vehicle like Telsa has in its battery Gigafactory. No one at Apple has ever said anything like JB Straubel, Chief Technical Officer and Co-founder of Tesla Motors, has said:To read this article in full or to leave a comment, please click here

Why Do TFD Delegates Hate Gartner?

A thought, since I’ve just returned form Networking Field Day 9: I’ve heard it said that delegates to Tech Field Day events hate Gartner; that this is stupid, or that it’s some other form of snobbery. It’s certainly true that on the whole, TFD delegates do not like to see Gartner slides in presentations.

That Gartner Slide

So why do Tech Field Day delegates hate Gartner?

We don’t.

We do.

We don’t, but we do. It’s complicated.

Hey, it’s complicated, alright?

Bonus points for obvious movie reference identification. So look, here’s the thing. You folks reading this blog are likely pretty intelligent. The fact that you read tech blogs means you are looking to get information that will help you make a decision or solve a problem.

In my opinion, the problem with a company at Tech Field Day putting up a Gartner slide and maybe boasting that “we’re in the top right quadrant” is that it’s not what we think we’re there to hear. We’re sitting in front of the actual people who make the product, and instead of convincing us of their product’s merits by telling and showing us how amazing it is, they’re saying “Here’s what Continue reading

Researcher faults unlocking policies from Sprint and T-Mobile

Sprint and T-Mobile don't fully comply with a series of voluntary smartphone and tablet unlocking policies, even though both companies were praised last week by the Federal Communications Commission (FCC) for doing so, according to an independent analysis performed by a former developer of unlocking software."Sprint and T-Mobile aren't delivering on half the commitments they made to the FCC," said Sina Khanifar, a Web developer who conducted the analysis on his own by comparing carrier unlocking policies with a voluntary Code the carriers committed to follow.To read this article in full or to leave a comment, please click here

First look: Windows 10 preview for smartphones is off to a slow start

Last Thursday, Microsoft released its long-anticipated Windows 10 Technical Preview for smartphones. This first public release of Windows 10 for smartphones improves on many Windows Phone 8.1 features, but it offers few compelling new capabilities. Also, while Win10 TP for smartphones is supposed to run universal-style apps (the latest incarnation of what have been called Metro, Modern, and Windows Store apps), there's still little congruence between the new universal smartphone apps and their big-screen universal namesakes.Note that Microsoft limited the beta bits to Lumia 630, 635, 636, 638, 730, and 830 smartphones. The advanced Windows Phone fan base, which has been migrating to the Lumia 930 (Icon), 1000, 1300, and 1500 series, got snubbed. Microsoft explained that it didn't bring this first beta to the 930 or the 1520 because of conflicts with "a feature that will be coming soon called partition stitching."To read this article in full or to leave a comment, please click here

Sony, Microsoft may face same Google Glass challenges

While Google has put the prototypes of its Glass wearable back under wraps, the market is getting a bit more crowded.Japanese electronics manufacturer Sony announced Tuesday that it is developing an Android-compatible pair of computerized eyeglasses designed to show users low-resolution imagery, as well as text. The device is also equipped with a camera.At least one industry analyst said he doubts the new competition will put any added heat on Google, since every company trying to pursue computerized eyeglasses is facing the same challenges.To read this article in full or to leave a comment, please click here

How a university’s data center overhaul makes a green impact

To say that University of Cambridge deployed disparate and diverse data storage and data center infrastructure would be a vast understatement. In a 2013 IT review, data center manager Ian Tasker and his team discovered almost 200 servers across the University's 120 departments. These installations ranged from single servers housed in closets to larger rooms containing 20 to 30 servers, but all contributing to a major drain on power and cooling resources, as well as creating one heck of a management headache."Our IT review is a periodic way for us to look at how we're carrying out the responsibilities of IT, and how to best align IT with the work of the university. What we found was everything was fragmented and each department was doing their own thing when it came to provisioning, storage and management. Where we had a small number of racks, they weren't powered or cooled efficiently, and that was our other mission: to reduce our carbon footprint as a university by about 34 percent by the year 2020," Tasker says.To read this article in full or to leave a comment, please click here

Thinking about buying a refurbished smartphone? You’re not alone

Buying refurbished smartphones will become increasingly popular in the next couple of years, with consumers benefiting from increased competition.That more consumers are considering getting a refurbished smartphone isn’t a surprise. With product innovation slowing down, smartphones that are a generation or two old look increasingly attractive compared to their new counterparts.This will help the worldwide market for refurbished phones that are sold to end users more than double from 56 million units last year to 120 million in 2017, according to market research company Gartner. That’s much more impressive than the anticipated 60 percent growth in sales of new smartphones in the same time period.To read this article in full or to leave a comment, please click here

Show 224 – HTTP2. Its The Biggest (Network) Thing Happening on the Internet Today

HTTP/2 is now submitted to the RFC Editor and will bring major changes to networking. Efficient design means smaller firewalls, less bandwidth and faster response times for users. And the default to encryption means that transparent caches, proxies, IDS/IPS and other network security systems will be seriously impacted.

BlackBerry sues Typo again over latest version of add-on keyboard

BlackBerry has filed another lawsuit against the makers of the Typo keyboard, claiming that the new version of the iPhone accessory also copies its designs and patents.Judge William Orrick of the U.S. District Court for the Northern District of California last year agreed to BlackBerry’s request to temporarily block sales of the first version of the Typo add-on keyboard, which BlackBerry claimed was a knock-off of keyboards on its phones.BlackBerry believes that there is still demand for phones with physical keyboards, despite the introduction by most vendors like Apple of smartphones with only touchscreen interfaces. It announced, for example, the Q10 in January 2013 and the Classic in February last year, which combine a touchscreen and a physical keyboard.To read this article in full or to leave a comment, please click here

Free-Form Discussion at CLEUR

I was fortunate enough to be invited out to Milan, Italy for Cisco Live Europe, and we had a few interesting discussions about a multitude of topics. One of them was more free-form than the others, and focused on defining SDN, what it’s value is, and where that value is most realized.

Check out this video recording of the session; it was good to get a few perspectives from non-networkers, since I’m sure their perspective is different from the network administrator’s as it pertains to the ongoing shift in this industry:

For the record, it’s not fair to say that VLAN provisioning takes two weeks, even after change approval. What the server administrator is usually asking for is an entirely new logical network, and there’s much that has to happen in order to do this, the easiest of which is tagging the server port on the ToR. These networks have dependencies, like IP space, firewall and load balancer contexts. Sometimes, routing configurations have to be changed. Is the current provisioning model optimal, or even acceptable? Of course not - that’s why I’m focusing on the newer, more automated methods. However, there’s more than meets the eye here.

I also want Continue reading
