Why America’s obsession with STEM education is dangerous – The Washington Post

A good opinion piece on why America needs more than just STEM education.

Twenty years ago, tech companies might have survived simply as product manufacturers. Now they have to be on the cutting edge of design, marketing and social networking. You can make a sneaker equally well in many parts of the world, but you can’t sell it for $300 unless you’ve built a story around it. The same is true for cars, clothes and coffee. The value added is in the brand — how it is imagined, presented, sold and sustained. Or consider America’s vast entertainment industry, built around stories, songs, design and creativity. All of this requires skills far beyond the offerings of a narrow STEM curriculum.

Map of Triangle-area Google Fiber huts

Google Fiber in the Triangle

Google Fiber in the Triangle


A News and Observer story alerted me to the recent approval by Raleigh City Council of 10 Google Fiber hut sites in the city. A quick look at the city council minutes showed me where they were. I took a few minutes this afternoon to map these sites onto Google Maps to get a better look at where Google Fiber might soon be deployed.

The result is this Google Map. I have since added the four sites in Cary and one in Morrisville which have already been approved. I searched for approval of sites in Durham, Chapel Hill, Carrboro, and Garner but as far as I know these municipalities have not yet approved their sites. If someone learns that this has changed, please give me a heads up and I will add these sites to my map.

The upright Google Fiber bunnies signify fiber hut locations, while the horizontal bunnies indicate where conduit permits have been requested. I’ve also put an icon on Raleigh’s proposed Google FiberSpace at 518 W. Jones St in Glenwood South area.

The Earthquake That Will Devastate Seattle – The New Yorker

Here’s a terrifying story on the Cascadia Fault, which is overdue for an earthquake so devastating it will almost assuredly destroy Seattle. I love The New Yorker’s expert, in-depth writing.

When the 2011 earthquake and tsunami struck Tohoku, Japan, Chris Goldfinger was two hundred miles away, in the city of Kashiwa, at an international meeting on seismology. As the shaking started, everyone in the room began to laugh. Earthquakes are common in Japan—that one was the third of the week—and the participants were, after all, at a seismology conference. Then everyone in the room checked the time.

Amazon backs NC’s 1st large-scale wind farm | News & Observer News & Observer

Remember last year when I wondered why Amazon would suddenly start collecting state sales taxes even though it had no presence in the state? The N&O’s John Murawski reported yesterday that Amazon is investing in a giant wind farm in eastern North Carolina. Boom, there’s your “unspecified investment.”

With the estimated $20-$30 million Amazon is now collecting in sales taxes, Amazon’s wind farm is not only powering 60,000 homes, it’s also powering teacher salaries.

The world’s largest developer of wind-energy farms has teamed up with online retail giant Amazon to build a major wind farm in coastal North Carolina.Amazon, which is building a network of wind farms and also testing Tesla storage batteries, announced the project Monday. The Amazon Wind Farm US East, to be built in Perquimans and Pasquotank counties, will power the online retailer’s cloud-computing division, Amazon Web Services, as part of a corporate goal of achieving energy sustainability.

The sprawling 34-square-mile wind farm will start with 104 turbine spires rising from the state’s eastern flatlands. The $400 million energy project will be built by Spanish wind farm developer Iberdrola Renewables and will start generating electricity for Amazon’s data centers in late 2016.

Broadband Speeds Are Improving in Many Places. Too Bad It Took Google to Make It Happen. | MIT Technology Review

MIT’s Technology Review magazine praises Google Fiber for spurring broadband investment.

State and local governments had done little to disrupt the status quo or push ISPs to invest in upgrades. And governments also showed little interest in subsidizing, let alone fully paying for, a better infrastructure themselves. (There was money allocated to broadband investment in the 2009 stimulus bill, but it went mainly to wire underserved areas rather than lay fiber.) On the municipal level, most cities still had building regulations and permit requirements that, inadvertently or not, tended to discourage the laying of new line, particularly by new entrants. And in many cases, even if cities were interested in building or operating their own high-speed networks, state laws barred them from doing so. The result of all these factors was that the United States, slowly but certainly, began falling well behind countries like Sweden, South Korea, and Japan when it came to affordable, abundant bandwidth.

Five years later, things look very different. The United States is still behind Sweden and South Korea. But fiber-to-the-home service is now a reality in cities across the country. Google Fiber, which first rolled out in Kansas City in the fall of 2012, is now operating in Austin, Texas, and Provo, Utah, and Google says it will expand next to Atlanta, Salt Lake City, Nashville, and Charlotte and Raleigh-Durham, North Carolina, with another five major metro areas potentially on the horizon. The biggest impact, though, has arguably been the response from big broadband providers.

First Measles Death in US Since 2003 Highlights the Unknown Vulnerables – Phenomena: Germination

For the first time in 12 years, an American resident has died from measles. The victim was taking immunosuppressive drugs which made her vulnerable.

Last week, the CDC reported on a man who contracted measles after passing through an airport gate a full 46 minutes after an infected child passed through the same gate. Learn more about why measles is a scary disease here at Buzzfeed.

Shocking news today out of Washington state: For the first time since 2003, a resident of the United States has died of measles. If you wondered, based on my last post, what happens when measles infects unvaccinated people and travels with them in an untrackable manner, this is the answer: It sickens and kills people who are vulnerable for reasons over which they have no control.

Drones not yet cleared for takeoff

An Unmanned Aircraft System (UAS) or "drone"

An Unmanned Aircraft System (UAS) or “drone”


After having had such fun with the Structure Sensor I borrowed through the N.C. State Libraries Technology Lending program, I suggested that they consider lending quadcopters like the DJI Phantom 3. Drones like the Phantom 3 are so cutting-edge that they are far ahead of Federal Aviation Administration regulations, so much so that many common-sense uses of drones (or as the FAA calls them, “unmanned aircraft systems” or UAS) are currently banned outright.

Like other university libraries, N.C. State Libraries would love to lend out drones but the present legal limbo with the FAA prevents that from happening. You see, what many people don’t realize is that the FAA is in charge of the nation’s airspace from the ground up. Not just 500 feet and above but starting at the ground. Public property, private property, it doesn’t matter. If you fly anything, anywhere, the FAA makes the rules.

Scanning 3D objects with the Structure sensor

This is a 3D rendering of me

This is a 3D rendering of me


As an employee of a company located on N.C. State’s Centennial Campus, I have access to the tech lending program of the N.C. State libraries. One of the more interesting devices I found there two weeks ago was a 3D scanner kit consisting of an iPad Air and an Occipital Structure 3D Sensor device. Not knowing much about it I thought I would take it home for a week and see what it could do.

The sensor integrates with the iPad by using the iPad’s built-in camera in conjunction with the Structure sensor. The sensor paints the scene in front of it with infrared grid points. The sensor then detects how this grid is bent by the object in the field and, together with the iPad’s sensitive accelerometers, computes the dimensions of the object. All of this happens in seconds and it’s quite amazing to watch!

Cheap Thoughts: variable-current EV charging

I’ve been mostly happy with our Siemens Level 2 EV charger. It’s simple to use with only two buttons, which I rarely need to press. Still, there is one feature the Siemens does not offer that I wish it had: the ability to adjust the current used based on my electricity rate plan’s Time of Use schedule.

Duke Energy offers a Time of Use – Demand (TOU-D) electric plan (which I’ve discussed in-depth before), meaning an electric customer gets socked with high fees based on how much electricity gets used at the same time.
