This is a fascinating look into the world of a saturation diver.
For 52 straight days this winter, Shannon Hovey woke up in the company of five other men in a metal tube, 20 feet long and seven feet in diameter, tucked deep inside a ship in the Gulf of Mexico. He retrieved his breakfast from a hatch (usually eggs), read a briefing for the day, and listened for a disembodied voice to tell him when it was time to put on a rubber suit and get to work. Life in the tube was built around going through these same steps day after day after day … while trying not to think about the fact that any unintended breach in his temporary metal home would mean a fast, agonizing death.
Hovey works in one of the least known, most dangerous, and, frankly, most bizarre professions on Earth. He is a saturation diver—one of the men (right now they are all men) who do construction and demolition work at depths up to 1,000 feet or more below the surface of the ocean.

LAS VEGAS – UFO investigators are hoping to obtain a treasure trove of Pentagon documents that were generated by a once-secret military study of flying saucers and other weird aircraft.The government confirms there was a UFO program. It supposedly ended in 2012, but the Pentagon has not yet released any reports or files.
The I-Team gives the first look at documents which prove the UFO study was real and was based in southern Nevada.

Looks like I may have found the orbital elements (TLEs) of SpaceX’s Starlink Internet satellites. I noticed on SatView’s site that three objects entered orbit on 22 February, one of which was SpaceX’s PAZ satellite. PAZ was the primary payload on SpaceX’s most recent Falcon 9 flight and the Starlink birds were the secondaries.
Following Satview’s links takes you to the real-time tracking of 43616U and 43617U (International Designators 2018-020A & 2018-020B), two satellites that are almost certainly Starlink’s TinTin A & B (or Microsat 2A & 2B). They show up in NORAD’s catalog as the bland descriptions of “Object B” and “Object C” and were launched from Vandenberg Air Force Base on the same day as PAZ. From CelesTrak:
So now I know both what to look for and where and when to look for it. Now I need to acquire the gear to acquire the signals, which might be the biggest stumbling block of all. Well, aside from actually decoding any signals I happen to get.
Yes, folks, this actually is rocket science.
I’m a little skeptical that a standing desk could be worse for you than sitting on your ass all day. I’m certainly not going to take as gospel a study with a mere 20 participants in it. As for the Canadian study, I have my doubts, too, but need to delve further into the science.
Often I think these studies are driven by the disdain that Sitters often show towards Standers. Desk discrimination is what it is.
There’s always that one person in the office—you know the one. The one with the standing desk. Whenever you happen to pass their cube you think, wow, there’s a person being proactive about their health. There’s someone fighting the good fight against modern society’s unavoidably sedentary lifestyle. Good on them, bad on me.
But is that really true? A growing body of evidence suggests that yes, sitting for long periods of time can have a detrimental effect on your health. But unfortunately, standing for large spans of the day isn’t that great either. And a recent study adds to this pile. This month in the journal Ergonomics, researchers report that when they had 20 participants stand for two hours at a time, subjects showed an apparent increase in lower limb swelling and decreased mental state.

Update 1 March: I found the satellites!
As my family and I strolled our neighborhood at sunset, my eagle-eyed son spotted a light in the sky sliding slowly away from us before fading. At first we thought it was the International Space Station (ISS) but it was too dim for that. We decided it was a low-earth orbit satellite and the conversation shifted to SpaceX’s recent launch of two low-earth-orbit test satellites for their proposed satellite Internet service, Starlink.
I have no idea whether the satellite we watched is a Starlink Satellite (more formally called TinTin A & B and previously known as Microsat 2A and 2B). I didn’t have my satellite tracking app fired up on my phone at the time. It did get me thinking, though, that it would be fun to track the TinTin satellites to see what I could discover.
A search on the Internet reveals very little information about these birds. I have not yet found the two-line elements (TLE) which describe their orbits. They haven’t been mentioned on my satellite-tracking email list, either.
What if I could locate them, then what? I’d like to try to collect whatever telemetry is being broadcast, even if it’s just beeps. Better yet, I could capture the data stream from the Internet side but that would be challenging to do anything with as it’s said to be encrypted. The birds do have imagery capability. What if I could tune into that and download an image snapped from orbit? Wouldn’t that be cool!
Monsieur Marchand is my new hero.
At the age of 105, the French amateur cyclist and world-record holder Robert Marchand is more aerobically fit than most 50-year-olds — and appears to be getting even fitter as he ages, according to a revelatory new study of his physiology.
The study, which appeared in December in The Journal of Applied Physiology, may help to rewrite scientific expectations of how our bodies age and what is possible for any of us athletically, no matter how old we are.Many people first heard of Mr. Marchand last month, when he set a world record in one-hour cycling, an event in which someone rides as many miles as possible on an indoor track in 60 minutes.
Mr. Marchand pedaled more than 14 miles, setting a global benchmark for cyclists age 105 and older. That classification had to be created specifically to accommodate him. No one his age previously had attempted the record.
Mr. Marchand, who was born in 1911, already owned the one-hour record for riders age 100 and older, which he had set in 2012.
It was as he prepared for that ride that he came to the attention of Veronique Billat, a professor of exercise science at the University of Evry-Val d’Essonne in France. At her lab, Dr. Billat and her colleagues study and train many professional and recreational athletes.
Plastics expert Dr. William Carroll of Indiana University says Elon Musk’s Starman Tesla is no match for the rough-and-tumble environment of space.
The real forces that will tear the car apart over hundreds of millions of years in space, Carroll said, are solid objects and — most importantly — radiation.
Even if the car avoids any major collisions, over very long time horizons, it’s unlikely the vehicle could avoid the kind of collisions with micrometeorites that leave other space junk riddled with craters over time, Carroll said.
But assuming those collisions don’t completely tear the car apart, the radiation will.
Down on Earth, a powerful magnetic field and the atmosphere largely protect human beings (and Tesla Roadsters) from the harsh radiation of the sun and cosmic rays. But spacefaring objects have no such protections.

Oh, for fuck’s sake. The story of today’s erroneous tsunami warning quoted AccuWeather CEO Barry Myers, who Trump tapped to lead NOAA. I had no idea that Myers was up for this position.
This would be another case of Trump trying to destroy government from the inside. Myers’s company AccuWeather tried to quash free forecasts: one of the most useful and lifesaving services of the federal government.
Fuck this guy and fuck Trump for nominating him.
As extreme weather conditions and natural disasters lay waste to Northern California and Puerto Rico, Donald Trump is poised to hand over control of the National Oceanic and Atmospheric Administration—the government organization that focuses on weather and climate research—to a known opponent of the agency. Barry Myers, the C.E.O. of for-profit weather forecasting service AccuWeather, has supported measures that would limit how much information the National Weather Service can publicly release, so private companies like his can use N.W.S. data to sell their own products to consumers.

This is appalling. People are dying because they can’t afford insulin.
The U.S. health care is broken. Only single-payer will fix it and I will support any politician who supports it. No one should die over profits!
On May 20, 2017, Smith turned 26, aging out of his parents’ insurance. Because he was a single man with a decent job, Smith didn’t qualify for subsidies under the Affordable Care Act. The most inexpensive plan Smith and his mother could find on the Minnesota exchange was around $450 per month with a $7600 deductible. Smith could have afforded the monthly premiums, but the deductible made the plan too expensive. Although the family had been researching plans for Smith since February, he had to go off of health insurance entirely.
When Smith went to the pharmacy to pick up his insulin in early June, the bill was over $1300 without insurance. He couldn’t afford the medicine that day, and decided to ration his remaining insulin until he was paid. Smith did not tell his family that he was adjusting his carbohydrate intake so he could lower his dosage.
“He knew the signs of being in trouble with his diabetes,” Smith-Holt told the HPR. “But when your body starts shutting down like that, you’re not making very clear, rational decisions.”
On June 25, Smith went to dinner with his girlfriend, where he complained about stomach pains. It was the last time anyone saw him alive. He called in sick to work the next day. On June 27, Smith was found dead in his apartment.

This isn’t a new story but it’s one that I found very enlightening on the topic of digital audio formats.
Pono Music’s roaring success on Kickstarter, raising $4.3 million so far, shows that thousands of people believe better audio quality is worth paying for.
The company — backed by star musician Neil Young and selling a $400 digital audio player along with accompanying music — promises people will hear a difference between Pono Music and ordinary music that’s “surprising and dramatic.” The company’s promise is based in part on music files that can contain more data than not only conventional MP3 files, but also compact discs.
There’s no doubt that highly compressed music files, played over tinny laptop speakers or cheap earbuds, leave a lot of room for improvement. But outdoing CD quality? That’s a harder sell.
