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

The Upload: Your tech news briefing for Wednesday, February 18

Facebook wants us all to create VR contentFacebook is actively looking at ways to make its $2 billion acquisition of virtual reality headset maker Oculus Rift part of the social media experience. At a re/code conference Tuesday, Chief Product Officer Chris Cox said the company is working on VR apps, and he also said he expected users to one day upload and share VR content. As re/code pointed out, creating that content is currently a nontrivial affair; Cox also told the publication that “We’re probably a long way from everyone having these headsets.”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.

Israel targeted by malware packaged with pornographic video

Israeli institutions have been targeted by an Arab-speaking hacker group that sought to extract sensitive documents, according to Trend Micro.The campaign, which Trend called Operation Arid Viper, focused on sending phishing emails to targets. Those emails came with malware packaged with a short pornographic video, according to the company’s report.The phishing emails were sent to targets including a government office, infrastructure providers, a military organization and academic institutions in Israel and Kuwait.The attacks “targeted professionals who might be receiving very inappropriate content at work and so would hesitate to report the incident,” Trend wrote. “These victims’ failure to act on the threat could have then allowed the main malware to remain undiscovered.”To read this article in full or to leave a comment, please click here
