Alexander: Do those new chip-based credit and debit cards need protection? – StarTribune.com

I was chatting with the cashier supervisor at the local Large Mart, asking if Large Mart would be going to the new, chip-based credit cards.

“Yeah, we’re going to get those within the next few weeks,” he said.

I nodded. “Well, I’ve been the victim of credit card fraud so many times that I welcome the extra security.”

“The new cards also have security problems,” the supervisor answered. “With the chip cards, thieves can read your cards while they’re in your wallet.”

That was news to me. The chip on my card is definitely a contact card, and any RFID-based credit card would be wide open to the world and truly offer zero security. Fortunately, banks aren’t using RFID, but Near-Field Communication (NFC), and only in some chips (i.e., not in the U.S. at this time). NFC has a range of 2-4 inches, which is about 1/12th the range of an RFID tag. Also, an NFC-capable device does encryption, while an RFID tag would only stupidly transmit static numbers.

So, tl;dr: current chip cards in the U.S. are contact-only, and NFC chips won’t be readable outside of your wallet. Bring on the chipped-card revolution, I say!

Q: Do the new EMV chip credit cards (named after the developers, Europay, MasterCard and Visa) require a protective cover so that they can’t be scanned by nearby thieves, just as RFID (radio frequency identification) cards do? Do other radio frequency ID cards, such as hotel key cards, pose a risk of identity theft?

A: There are two types of credit cards using EMV chip technology. One is read by a slot in a point-of-sale ­terminal; the other is read by holding the card near the sales terminal.

If your EMV card requires physical contact inside a reader, its transactions and account information can’t be scanned remotely by thieves. If it is a contactless card, there’s a chance it could be read by nearby spying equipment, although the credit card ­industry says that’s unlikely.

This Hacker’s Tiny Device Unlocks Cars And Opens Garages | WIRED

Remember two years ago when I was captivated by a mystery device thieves were using to open car doors? This $32 device might just be it.

Thus, all the neighbors who have been claiming stuff was stolen from their cars when they knew their doors had been locked may be telling the truth.

At the hacker conference DefCon in Las Vegas tomorrow, Kamkar plans to present the details of a gadget he’s developed called “RollJam.” The $32 radio device, smaller than a cell phone, is designed to defeat the “rolling codes” security used in not only most modern cars and trucks’ keyless entry systems, but also in their alarm systems and in modern garage door openers. The technique, long understood but easier than ever to pull off with Kamkar’s attack, lets an intruder break into cars without a trace, turn off their alarms and effortlessly access garages.

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.

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.

Cheap thoughts: discouraging nighttime thefts from cars

Saturday night as I lay sleeping in the bedroom just above, a thief quietly slipped up my neighbor’s driveway to his car, tried the door handle, and slipped away. He and his buddy found my other neighbor’s door unlocked and ransacked the car.

This happens from time to time when you live in the big city. You either keep your car locked (always a good plan) or suffer potential thefts. There aren’t many tools to it from happening.

Being a law-and- order-minded geek, I have been considering ways to catch some of these crooks. One way involves altering the battery pack on a laptop to conceal a GPS-enabled smartphone, which would lead cops directly to the thief. Why the battery? It does no permanent damage to the laptop and the remaining cells in the battery could power the laptop long enough for a crook to be convinced it works.

Moore’s Law is dead – Business Insider

“Moore’s Law,” the observation that computer chips has doubled in capacity every two years, is hitting the limits of physical matter. This is a fascinating look at the miraculous physics that makes our smartphone-enabled world possible, and where we go from here.

When Gordon Moore wrote his paper, the most complex chip had only 64 transistors on it. Back around 2000, the processor on my home-built PC was made using a 180-nanometer process technology. The one I’m using now, also built out of parts, uses a 22-nanometer technology. The amount of transistors on the chip has increased from 37 million to over 1 billion in only 15 years.

Moore’s law is based on shrinkage. How small can you shrink the manufacturing process? The smaller you can do it, the more components you can fit on a silicon wafer. We’ve been really good at that for over 50 years.

But we’re hitting limits with how small we can make these components. In fact, over the past several years, it’s become harder and harder to shrink the manufacturing process. Some experts predict we’ll hit the end of the line by 2020. Some say it will be 2022. Either way, it’s going to happen pretty soon.

Past Gas, literally

A backhoe digging in this ditch ruptured a gas main this morning

A backhoe digging in this ditch ruptured a gas main this morning


This morning I got to play hero, ironically driving our electric car with our “Past Gas” license plate.

I was driving to work as usual when I turned off of Hillsborough Street onto Ashe Avenue, a spot where a new apartment building is going up. As I go by, I see a construction worker leap off a backhoe and race across the road. Others scurried away as well, eyes wide with fear. It was then that I smelled natural gas and realized the deafening roar I was hearing was the sound of a busted gas main. Yikes!

I rolled down the road for a moment or two while frantically fumbling to unlock my phone to dial 911 (I temporarily forgot I can do this from the locked screen, but whatever). I blurted out what I saw and heard to the dispatcher and gave my name and number. Though the dispatcher told me they were already sending someone out, I didn’t see or hear any first responders so I took matters into my own hands. I figured I might not be trained in how to direct traffic but any idiot can block traffic, so I pulled my car across the oncoming lane and got my geeky yellow safety vest and my emergency light out from the trunk.

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.
