Oh Columbia, you haven’t aged well

2400 Bee Ridge Road, July 2016.


As an IBM Brat I moved around a lot as a kid (the inside joke is that IBM stands for “I’ve Been Moved”). This made it tough for me to think of home those times I was homesick while in the Navy but it also sort of locked in a time with a place in my memories. In my head, the places I’ve lived will always have a strong association with the brief time I’ve lived there.

Such is the case with Columbia, South Carolina. Columbia was my home for my 3rd grade to 7th grade school years, or 1979 to 1983. There was an actual city with Columbia, different than coming from Spanish Fort, Alabama, though our neighborhood of Spring Valley in northeast Columbia was definitely suburban. Spring Valley is a relatively wealthy, gated community with a private security guard and country club. My brothers and I would walk together with no attending parents to elementary school at Lonnie B. Nelson and we would ride our bikes all over the sprawling neighborhood to visit friends. It was a great place to grow up and provided me with important opportunities that helped make me who I am today.

My Uncle Bill’s death last year provided me the opportunity to catch a new glimpse of my old neighborhood as my brothers and I drove through on our way to his funeral. We lingered long enough to take photos of our old home and our school before continuing on, driving out Two Notch Road to continue our journey on I-20.

During my time there Two Notch Road was the big commercial road, leading from Spring Valley to the new (in 1979) Columbia Mall. Even then it was dotted with the ubiquitous flashing-light-arrow advertising signs, fast-food joints, and the like. These business would sprout up like weeds – wherever they could and seemingly with no thought to how they all fit together.

That time I got a Florida driver’s license without knowing it

One day a few weeks ago I was poking around my Facebook message inbox, looking for those messages that get stuck there when they are sent from someone who isn’t a Facebook Friend. Several messages were weeks or months old but one of them had been sent three days prior in an urgent attempt to contact me.

Reading further, the sender owned a store in western North Carolina and said she wanted to warn me of someone’s possible attempt to steal my identity. She didn’t want to discuss it online, she said, but left me her number so I could call.

Identity theft? Urgent matter? Wouldn’t discuss it online? I was quite skeptical of the whole thing; not only quite sure that my identity hadn’t been stolen, but also how and why was this woman contacting me through Facebook? Deciding I had nothing to lose, I picked up the phone the next day.

D.C. police issue warrant for 12 on Turkish security team in May brawl – The Washington Post

DC Police are looking for these thugs. With any luck they’ll never set foot in America again.

Authorities in the District said Thursday that they have criminally charged a dozen members of Turkish President Recep Tayyip Erdogan’s security team who authorities say attacked protesters outside the ambassador’s residence in May.

At a news conference, D.C. Mayor Muriel E. Bowser (D) and Police Chief Peter Newsham explained the charges against the suspects, who are all believed to be in Turkey.

“I condemn this attack,” Bowser said, vowing that the city will “defend the First Amendment.”

The charges come nearly a month after the clashes at Sheridan Circle along Massachusetts Avenue’s Embassy Row, outside the residence of the Turkish ambassador. Police and other officials say various members of the visiting Erdogan’s security team, some of them armed, attacked a group protesting his regime as police struggled to restore order and bystanders recorded the scene with phones.

As early as 2007, analysis demonstrated that 400-V dc distribution had advantages; Now there’s a way to implement it.


Is DC power the wave of the future for computing environments?

Power distribution in data centers used to emulate the architecture of old telephone central offices. A “rectifier” would step down and rectify the ac from the power line and use it to charge banks of batteries that provided an unregulated 48 V dc, which was distributed around the facility to run the telephone equipment in the racks.

Since at least 2007, data-center engineers have been talking about distributing 400 V dc (sometimes 380 V). Data centers are bigger and use a lot more power than telco central offices. At a minimum, higher voltage distribution would mean lower I2R losses and/or thinner power-distribution cables.

Jumpseat: It’s All About the APU | Flying Magazine

I enjoyed this pilot’s story of how a broken APU on his aircraft caused a mess.

For more than 50 years of jet airliner operation, the APU has been an integral part of airplane independence. The APU is a small jet engine located within the structure of the fuselage. With today’s airliners, the unit is operable both on the ground and in flight. In flight, the APU provides both a backup source of electric power and a limited amount of air pressure at lower altitudes — usually below 20,000 feet.

On the ground, the APU is capable of being the sole source of electricity and the sole source of air pressure. Air pressure from the APU is the standard method utilized in starting the engines. When air is not available, starting becomes problematic. On this particular trip, an inoperative APU became more problematic than my copilot and I could have ever imagined.

Even moderate drinking can damage the brain, claim researchers | Society | The Guardian

Drinking even moderate amounts of alcohol can damage the brain and impair cognitive function over time, researchers have claimed.

While heavy drinking has previously been linked to memory problems and dementia, previous studies have suggested low levels of drinking could help protect the brain. But the new study pushes back against the notion of such benefits.

“We knew that drinking heavily for long periods of time was bad for brain health, but we didn’t know at these levels,” said Anya Topiwala, a clinical lecturer in old age psychiatry at the University of Oxford and co-author of the research.

50 Years Ago: NSA’s Deadliest Day | Observer

June 8, 1967 was the worst day in the history of the National Security Agency. On that date, Israeli airplanes and torpedo boats mauled and nearly sank an American spy ship in international waters, killing or maiming most of its crew. This tragedy appears as a footnote to Israelis, an unpleasant sideshow of their victorious Six Day War, while official Washington preferred the embarrassing episode be forgotten. But NSA has never let the Liberty and her ill-fated crew disappear from memory altogether.

Amazon kills unlimited Amazon Cloud Drive option

Recently I had a scare when our home storage server went on the fritz. Years of photographs, videos, and files were suddenly in jeopardy as they appeared to vanish. Being a resourceful geek, once I caught my breath I was able to revive everything. Still, it was enough of a scare that I accelerated my quest for a good, offsite place to back up our files.

Part of this quest was getting gigabit fiber Internet at home, which I recently did when I could no longer wait for Google Fiber and signed up with AT&T Fiber. Untangling this brave new world has kept me busy recently, not leaving much time for blogging. I will have lots to say about this in the near future but suffice to say that having a fat pipe at home makes it easier to do any kind of backup to the cloud.
