“My best friend, he’s the king of karaoke…”

We started off our anniversary weekend by attending the birthday party of a friend of Kelly’s Saturday night. There was a karaoke machine present and, of course, I can never resist doing some singing. I did about 6 songs to rave reviews, with some people asking if I’ve done this before. It’s all very flattering but it did get me thinking if I could find a band and maybe take my singing more seriously.

Our family’s been asked if we can rejoin the Highlanders and play some gigs this fall but it appears our ever-crazier schedules won’t allow for it. Plus there’s no singing; the Highlanders play instrumentals. I enjoy being on stage and playing guitar so adding singing would be even better.

So now I’m asking myself if I have the time it takes to rehearse with a band. It might take time but it wouldn’t seem like work if I’m doing music, so maybe this will actually happen.

17 Years of wedding bliss (well, mostly)

Yesterday marked 17 years of marriage for Kelly and me, still going strong. We celebrated by hauling ourselves and our kids off to multiple practices, meetings, and events, so pretty much a typical day. We Turners have lots of interests and solving the logistical challenges take up most of our time. It’s all good, though. We’re busy but happy. With many friends reaching Stage Empty Nest now, I know that the frantic pace we keep won’t continue forever and I’m sure to miss is once it’s gone.

Kelly and I are going out for our celebratory dinner this evening. Of course, it will occur between taking one kid one place and then taking the other kid another place. Ah, life!

Rachel Rosoff

Saturday morning, while my family was enjoying the Labor Day weekend, an Enloe High School student named Rachel Rosoff was reporting to work as a lifeguard at a North Raleigh neighborhood pool. Unbeknownst to her, the pool had somehow become electrified, and she was found floating face-down in the water by an arriving coworker who could not rescue her without becoming a victim himself. She was buried yesterday.

I’ve been thinking of Rachel over the past few days. She had many of the same interests that my kids do. I’ve probably even watched her perform with the Improv group at Enloe’s recent open house.

It’s terrifying to me as a parent how quickly lives can be turned upside-down, how you can work to make things safe and still tragedies happen. One moment Rachel was ready to take on the world and her world ends the next. Terrifying and so sad.

No, I didn’t know Rachel or her family but I feel like she and they are part of my family. I hope the Rosoff family finds some peace.

Tracking planes with dump1090

A RTLSDR receiver and dump1090 can track planes hundreds of miles away.

A RTLSDR receiver and dump1090 can track planes hundreds of miles away.

As an amateur radio operator and full-time geek, I’ve always been interested in the convergence of technologies, especially when the convergence scratches a few of my itches. One one of my latest hobbies is tracking commercial airliners through their ADS-B broadcasts. It’s a hobby that doesn’t take much time outside of setting it up. In about two hours, I configured a receiver, built an antenna, and set up software that shares what I find with the world, and all for under $30. Here’s how I did it.

The ADS-B protocol is a digital “status update” signal broadcast by airplanes which updates other aircraft around it with important location information and the like. The FAA would eventually like to see ADS-B take the place of ground-based radar but not all airplanes use it yet. Transceivers are still pricey and owners of general aviation aircraft like Cessnas largely haven’t yet adopted the system. There’s an amazing amount of data being sent and anyone with the proper receiver can intercept it (oops, that’s what we called radio reception when I was a Navy cryptologic technician), and that receiver can be dirt-cheap like the RTLSDRs.

Three years ago the radio-geek world was set ablaze when it was discovered that a mass-market DVB-T USB device had the ability to become a software-defined radio, basically a wide-range receiver that can easily decode almost any signal. Hobbyists soon were using these $15 RTLSDR dongles for just about everything, including tracking airplanes. I had a few lying around that weren’t really being used for anything so I hooked one up to my Raspberry Pi

Apple defends decision to remove 3.5mm headphone jack, cites “courage” | Ars Technica

I want to love Apple. I really do. But then Apple does something boneheaded like phase out a perfectly-good 3.5mm headphone jack in favor of its own, $160 proprietary headphone technology and I want to throw out every Apple product in my home.

Apple doesn’t want its customers to have choices. It has become the Microsoft of the 2000s. “Courage,” my ass. How about greed? How often do you think Apple’s customers will lose these loose, pricey earbuds?

"Airpods," a.k.a. overpriced junk

“Airpods,” a.k.a. overpriced junk

SAN FRANCISCO—Apple Senior VP Phil Schiller took the stage at Wednesday’s iPhone event to announce the news most tech geeks had been expecting: the iPhone will leave the 3.5mm headphone jack behind. It was Schiller’s job to justify why Apple was doing so, and he defended the company’s decision by citing three reasons to move on—and one word: “courage.”

Schiller explained to the San Francisco event crowd that Apple would push the Lightning port standard for wired headphones and push a new proprietary wireless standard, driven by the new “W1 chip” in iOS devices, which Schiller called Apple’s first wireless chip.

The 3.5mm port, on the other hand, has to go, Schiller said, because the company can’t justify the continued use of an “ancient” single-use port. He described the amount of technology packed into the iPhone, saying each element in Apple’s phones is fighting for space, and it’s at a premium. And while every iPhone 7 and 7 Plus will include a Lightning-to-3.5mm adapter, Schiller was a lot more bullish about the company’s wireless-audio standard.

SpaceX’s Explosion Reverberates Across Space, Satellite and Telecom Industries – The New York Times

This is a fascinating look at all the dominoes that fall when a rocket like SpaceX’s explodes.

The explosion of a SpaceX rocket last Thursday will have an impact across the space industry, far beyond the losses on the launchpad at Cape Canaveral, Fla.

An Israeli satellite operator’s deal to sell itself to a Chinese company is imperiled. Planned launches of communications satellites that support international mobile phone service and digital television are delayed and put in doubt. NASA’s cargo deliveries to the International Space Station will probably be disrupted.

All of them are customers of the Space Exploration Technologies Corporation, or SpaceX, whose rocket exploded in Florida. The private space launch company, led by the entrepreneur Elon Musk, has a generally solid safety record.But last week’s setback and a failed launch last year, when its rocket carrying a NASA cargo fell apart in flight, are raising questions about SpaceX, a company that has risen rapidly by offering lower costs and promising accelerated launch schedules.

Inside The Federal Bureau Of Way Too Many Guns | GQ

Anytime a cop in any jurisdiction in America wants to connect a gun to its owner, the request for help ends up here, at the National Tracing Center, in a low, flat, boring building that belies its past as an IRS facility, just off state highway 9 in Martinsburg, West Virginia, in the eastern panhandle of the state, a town of some 17,000 people, a Walmart, a JCPenney, and various dollar stores sucking the life out of a quaint redbrick downtown. On any given day, agents here are running about 1,500 traces; they do about 370,000 a year.

“It’s a shoestring budget,” says Charlie, who runs the center.
