Network Documentation Series: Physical Diagram

Introduction to the Physical Diagram This article is a quick tutorial for creating and maintaining a physical network diagram. I prefer to use the term “physical” instead of “L1″ because it is more easily understood by somebody unfamiliar with the OSI model. It also removes the assumption (made by many non-technical people) that “L1″ and […]

IBM muscles up on OpenStack with Blue Box buy

Betting that demand for hybrid clouds will grow strongly, IBM has acquired Blue Box, which specializes in offering OpenStack open source cloud hosting services.IBM will use Blue Box’s technology and infrastructure to help its customers adopt hybrid cloud computing, so that their workloads can be easily moved between a public cloud and their own data centers.A private company, Blue Box gives organizations an alternative to setting up and deploying the OpenStack internally, offering the software stack as a service instead. This allows an organization to control workloads from a single console whether they run on Blue Box’s private cloud or on internal infrastructure.To read this article in full or to leave a comment, please click here

Fraud campaign installs rogue app on non-jailbroken iPhones

Cybercriminals in Japan are targeting iPhone users with an online scam that tricks them into installing a malicious application when they attempt to view porn videos.This type of attack, known as one-click fraud, is not new and has been used for years against Windows, Mac and Android users. However, what’s interesting in this particular case is that it works even against non-jailbroken iPhones.Apple tightly controls how iOS apps are distributed to users by forcing developers to publish them on the official App Store where they are subject to Apple’s review procedures. However, there are exceptions to this rule in the form of special development programs for which participants have to pay extra.To read this article in full or to leave a comment, please click here

IT/IT: Resume Building

It’s a discussion in meeting rooms, boardrooms, hotel conference rooms, and post-conference cocktail parties: Why isn’t IT working? Ask anyone in a corporate or government job and you’ll get an earful. As I was writing this book, I’d occasionally throw the question out to friends, clients, and beleaguered airplane seatmates. The responses come fast and furious. They don’t speak our language. They’re too focused on resume building and tinkering, not on driving business value.
The New IT

This single quote describes much of the circuit of the world for an engineer. If I spend my time on driving business value, then I’m appreciated by my current employer — at least until they change systems, anyway, and throw me out on my ear because my skills aren’t “current.” If I spend my time keeping my skills current, so I can add business value, well, I’m not driving current business value, and hence I’m “isolated,” a “tinker in the corner,” who doesn’t understand nor care about the “real problems facing the business.”

What’s the solution? A little “bump in the training budget” isn’t going to fix this. Rather, this is going to take restructuring the way IT thinks about business, Continue reading

How CIOs can reduce shadow IT in government

If government CIOs want to bring IT out of the shadows, they need to start by understanding what kind of tools agency personnel need to do their jobs.That's one of the chief takeaways from a new study looking at shadow IT in the government -- those unauthorized applications and services that employees use without the permission of the CIO and the tech team.MORE ON NETWORK WORLD: 26 crazy and scary things the TSA has found on travelers The new analysis, conducted by cloud security vendor Skyhigh Networks, identifies a startling amount of applications in use in public-sector organizations. According to an analysis of log data tracking the activities of some 200,000 government workers in the United States and Canada, the average agency uses 742 cloud services, on the order of 10 to 20 times more than the IT department manages.To read this article in full or to leave a comment, please click here

Tablets, laptops and desktops based on the new chip architecture are expected in the second half of this year.To read this article in full or to leave a comment, please click here

The Upload: Your tech news briefing for Wednesday, June 3

Senate finally reforms NSA surveillanceNearly two years after former NSA contracter Edward Snowden went public with revelations that the agency was collecting Americans’ phone records in bulk so that it could trawl through them at leisure, the U.S. Senate has finally acted to rein in what at least one court ruled was illegal surveillance. The Senate’s 67-32 vote Tuesday on the USA Freedom Act will allow a limited telephone records program at the NSA, and give it six months to transition its phone records database to U.S. telecom carriers.To read this article in full or to leave a comment, please click here

Microsoft isn’t giving up on basic phones, upgrades the Nokia 105

Microsoft has launched an upgraded version of the Nokia 105 phone, but a growing interest in smartphones will make it difficult for the company to repeat the success of the original version.The US$20 Nokia 105 is aimed at first-time mobile phone buyers and people looking for a long-lasting backup device for their smartphone, according to Microsoft, which decided to keep the Nokia brand for its most basic phones.The new model has a bigger phonebook, better voice quality and longer talk time. Users can choose between models that have one or two SIM slots. It still has a 1.45-inch screen and an FM radio.The original model was introduced in 2013, and has sold more than 80 million units to date. Repeating that will be hard for Microsoft, since consumers all over the world are increasingly choosing smartphones. Microsoft’s overall phone sales dropped by about 30 percent during the first quarter year-on-year, even though Windows smartphone sales increased slightly, according to Gartner. At the same time smartphones represented 73 percent of total phone sales, up from about 63 percent.To read this article in full or to leave a comment, please click here

Meg Whitman Tees up HP Enterprise and the Hybrid Cloud

It's a cloudy future for HP.

This startup promises a better way to buy or sell a used car

Who wants to buy a used car through eBay or Craigslist, when you need a mechanic to inspect it? Buying through a dealer can also be intimidating and expensive, with sales reps often having unclear agendas.Shift, an online startup, thinks it can solve those problems, and provide an easier way for people to sell their cars.The company provides a listing service for used car shoppers to browse other people’s cars, and let owners list their cars for sale. But more than a listing service, the company employs mechanics to perform inspections on cars for sale, and hires workers to gather sellers’ service records and vehicle history reports. Shift’s workers will also deliver used cars to prospective buyers for test rides, within an hour.To read this article in full or to leave a comment, please click here

Video: Implementing VLAN-aware Bridge with OpenFlow

Reinventing the wheels makes little sense. Implementing old solutions with new tools might be in the same category, but at least it shows you the power and shortcomings of the new tools.

Building a VLAN-aware bridge in OpenFlow is thus a mandatory case study, and as you’ll see in the video from the OpenFlow Deep Dive webinar, it’s not as easy as it looks. For more details, watch the whole OpenFlow webinar (6 hours of in-depth videos), which you also get by buying Advanced SDN Training or ipSpace.net subscription.

AMD to launch next-generation Fiji GPUs on June 16

Gamers, buckle up—AMD will launch its highly-anticipated graphics processing unit, code-named Fiji, on June 16 at the E3 conference.Many were expecting Fiji to launch at a press event at Computex on Wednesday, but that didn’t happen. Instead, AMD did show off key technology, which will first appear in Fiji and could give significant speed and power saving gains to future graphics chips.On stage, AMD CEO Lisa Su showed a chip for technology called HBM (high-bandwidth memory), which could make graphics chips faster and more power-efficient.HBM offers 3.5 times the bandwidth per watt of GDDR5, which is currently used in memory chips. Instead of being placed next to each other, HBM stacks memory chips, which are connected through a high-speed thread. HBM is also faster due a wider bus and its closer location to graphics processors.To read this article in full or to leave a comment, please click here

Comcast and TWC are (still) among the most hated companies in America

The annual American Customer Satisfaction Index for 2015 placed Comcast and Time-Warner Cable near the very bottom of all telecom and technology companies in the rankings, the researchers involved announced Tuesday.The ACSI’s ratings – on a 100-point scale – gave Comcast a score of 54 as a TV service provider and 56 as an ISP, well below the industry average of 63 in both categories. TWC received a 51 in the former category and a 58 in the latter. The ratings were based on the ACSI’s in-house analysis of survey responses from 14,000 Americans, which were collected during the first quarter of 2015.+ ALSO ON NETWORK WORLD: Ransomware creator apologizes for 'sleeper' attack, releases decryption keys + Intel to buy Altera for $16.7B, eyes IoT market +To read this article in full or to leave a comment, please click here
