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.

Why the “biggest government hack ever” got past the feds | Ars Technica

Ars Technica takes an in-depth look at the “biggest government hack ever,” the OPM hack that exposed over 4 million records of federal government employees.

As I posted to Twitter, while the NSA was busy monitoring Grandma’s phone calls, the Chinese made off with 4 million federal government employee records. Tell me again why we are spending billions on the NSA?

n April, federal authorities detected an ongoing remote attack targeting the United States’ Office of Personnel Management (OPM) computer systems. This situation may have gone on for months, possibly even longer, but the White House only made the discovery public last Friday. While the attack was eventually uncovered using the Department of Homeland Security’s (DHS) Einstein—the multibillion-dollar intrusion detection and prevention system that stands guard over much of the federal government’s Internet traffic—it managed to evade this detection entirely until another OPM breach spurred deeper examination.

Stepson of Stuxnet stalked Kaspersky for months, tapped Iran nuke talks | Ars Technica

A fascinating, in-depth account of how security firm Kaspersky was infected by (and later discovered) one of the world’s most powerful hacking tools.

“These guys are so confident to develop their entire platform based on this zero day it means if they get caught and this zero day is patched they probably have another one they can use, which I would say is a pretty scary thought,” he said. “Nobody develops an entire malware platform based on just one simple assumption that this zero day will work forever, because eventually it will be discovered and patched. And when it is patched your malware is not going to work anymore. I think that’s also very scary and quite impressive.”

Computer Space and the Dawn of the Arcade Video Game

Here’s a fascinating account of the creation of the first commercially-successful video game, Computer Space, and of the men who created it, Ted Dabney and Nolan Bushnell. Bushnell would go on to create Atari and, by extension, modern Silicon Valley.

Computer Space pitted a player-controlled rocket ship against two machine-controlled flying saucers in a space simulation set before a two-dimensional star field. The player controlled the rocket with four buttons: one for fire, which shoots a missile from the front of the rocket ship; two directional rotation buttons (to rotate the ship orientation clockwise or counterclockwise); and one for thrust, which propelled the ship in whichever direction it happened to be pointing. Think of Asteroids without the asteroids, and you should get the picture.

During play, two saucers would appear on the screen and shoot at the player while flying in a zig-zag formation.The player’s goal was to dodge the saucer fire and shoot the saucers.

Considering a game of this complexity playing out on a TV set, you might think that it was created as a sophisticated piece of software running on a computer. You’d think it, but you’d be wrong–and Bushnell wouldn’t blame you for the mistake. How he and Dabney managed to pull it off is a story of audacity, tenacity, and sheer force-of-will worthy of tech legend. This is how it happened.

Flexing the muscle of my electric vehicle

Our Ford Focus Electric

Our Ford Focus Electric


There are many days when I’m driving my electric vehicle (EV) that I’m focused on economy. I will try hard to accelerate smoothly, drive at the speed limit (or sometimes more slowly), and brake as gradually as I can. The reward is high efficiency driving, saving as much money as I can.

Yesterday was not one of those days! Having many different events to attend, stretched from one end of the city to the other, I decided to flex my EV’s muscles. On our Time Of Use (TOU) plan, weekend electricity is super-cheap, so why not have a little fun?

As I drove down 401 yesterday, I sensed the guy behind me was becoming annoyed with my efficient driving. He shifted over a lane in an attempt to pass me. Not only are EVs cheap to drive, they also have a ton of torque just ready and waiting. I let the guy pass but caught up with him at the next light, where we both were lined up.

You think my EV is slow? I mentally challenged him. Watch this!

Baltimore Police used secret technology to track cellphones in thousands of cases – Baltimore Sun

"In Baltimore, they’ve been using this since 2007, and it’s only been in the last several months that defense attorneys have learned enough to start asking questions," he said. "Our entire judicial system and constitution is set up to avoid a ‘just trust us’ system where the use of invasive surveillance gear is secret."

Google View

Sitting in the dentist’s chair, enduring the agony of another teeth cleaning yesterday, I thought of the perfect use for the Google Fiber system coming to Raleigh.

I was being forced to watch Time Warner Cable’s News14 channel in front of me and thinking about how TWC’s local news model works. It didn’t take many minutes of watching the video (thankfully without audio, as the suction hose was often going) to realize how boilerplate it is. The TWC guys have an establishing shot, then zoom in on something dumb like police lights reflecting off the stolen car, then move on to another thing. It was obvious that the video doesn’t really tell the story – in fact, it is repetitive and dull. I could choose not to look up between rinses and feel like I didn’t really miss anything.

Google Fiber: Kansas City offers Charlotte ‘Digital Divide’ lessons | The Charlotte Observer The Charlotte Observer

CharO talks about Google Fiber and the Digital Divide

In a past job in Kansas City, Julie Porter was part of an intense, door-to-door campaign to get residents in economically challenged, mostly minority neighborhoods to sign up for Google’s high-speed Internet service.

Community organizers didn’t want residents in these areas to face an even wider Digital Divide.

Now the head of a Charlotte housing agency, Porter has urged local leaders here to get an early start encouraging residents to embrace broadband service, long before Google Fiber makes its planned Charlotte debut.

“It was just very, very challenging,” said Porter, president of the Charlotte-Mecklenburg Housing Partnership, of the Kansas City situation. “I wanted to make sure that Charlotte didn’t have the same experience.”

Hillary’s Secret Email Was a Cyberspy’s Dream Weapon – The Daily Beast

Here’s a good, in-depth look at the perils Hillary faced when she opted to run her own mailserver.

The private email address for Hillary Clinton, which became the talk of Washington this week and created her first major speed bump on her road to the White House, has actually been freely available on the Internet for a year, thanks to a colorful Romanian hacker known as Guccifer.

On March 14, 2013, Guccifer—his real name is Marcel-Lehel Lazar—broke into the AOL account of Sidney Blumenthal, a journalist, former White House aide to Bill Clinton, and personal confidante of Hillary Clinton. Lazar crowed about his exploits to journalists, disclosing a set of memos Blumenthal had written to Clinton in 2012, as well as the personal email address and domain she’s now known to have used exclusively for her personal and official correspondence.

Few journalists noticed that at the time, and it caused no ruckus in Washington. But the fact that Clinton’s private email was now public means she was not just putting her own information at risk, but potentially those in the circle of people who knew her private address.

Apnea hacking

At a follow-up trip to my neurologist I mentioned catching myself not breathing occasionally at night, at which point he ordered up a sleep study. Unlike the previous sleep studies I’d done several years ago, this was a home sleep study. FedEx delivered a sleep study kit to my door Wednesday with instructions on how to use it.

ResMed ApneaLink Air

ResMed ApneaLink Air

We went to the kids’ wonderful Pieces of Gold presentation and got home late. I was in little mood to dig through the paperwork and assemble this thing, and yet I was also tired of being tired all the time. I fumbled through setting up this ResMed ApneaLink Air device that was about the size of a pack of cigarettes and had tiny hoses and wires poking out of it. Surprisingly, it was more comfortable than I thought and soon I was snoozing away.

My directions said to wear it two consecutive nights, so after the second night (last night), I prepared the kit for shipping back. As I wrapped the cables up, I noticed the USB port on the box.

Hmm, I thought. I bet this acts as a USB drive if I plug it into my laptop.
