In the Name of Love and Science

Wired for Sleep (Self Portrait)
The Mask...

I have a mild form of obstructive sleep apnea. Mild in the sense that I'm not in danger of dropping dead due to a heart attack (I'm also fortunate that I don't smoke, and never have). But it is bad enough that it's causing issues with being able to operate during the day, and I've lost my cognitive "edge", that ability to quickly solve problems. And in a technologically driven world like ours is, that's bad news.

What's worse is the snoring. That drives my wife crazy some nights when it's really bad. Either she leaves, or she pokes me to wake up and makes me leave. And it's reached the point where I just sleep in another bedroom at night so she can have a decent night's sleep.

I discovered a lot of this at a downtown sleep center in late December of last year. The diagnosis was made, and continuous positive airway pressure, or CPAP, was proscribed. From my perspective it's the mildest, least invasive technique for this problem. In CPAP you're given a special mask and connected to a machine that keeps the air pressure up around your face so that the air passages stay open. Not only does it keep you from snoring but you experience more REM sleep and have normal blood oxygen levels.

The Wires...

Last night was my second trip to the sleep center. That's where I was wired and fitted with a mask so that the techs could monitor my sleep while they tinkered with the CPAP air pressure to minimize the sleep apnea.

The Center...

The facility was nice and comfortable, and I was wired up around 11:30pm. The only problem was I couldn't fall to sleep. With all the wires, the mask, and the sound of air flowing around the mask's seals like Darth Vader combining with the low but constant sound of the CPAP machine next to the bed, I lay on my back trying desperately to relax and fall to sleep. I kept trying until around 2:30am in the morning, at which point I thought "screw this" and rolled over on my left side. As soon as I did that I immediately fell asleep and the watchful tech's got a good four hours of sleep data (with a lot of it REM activity recorded). And they found the right air pressue for the CPAP machine.

Normally when I have a night like that (and I've had my fair share) the next day is horrible. This morning at 6:30am I was a lot better. I can remember when I could live on just four hours of sleep. But not since I turned 50.

With the new sleep data I'm headed back to the sleep specialist at the end of May. Hopefully at that time I'll be given my very own mask and machine and I can move on to the next stage of this experiment, using it at home. In the mean time I'll have to keep doing what I've been doing already. But the wife is definitely happier about this, both for my sake as well as her's.

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…

vm networking problem fixed

Over the weekend I upgraded to Windows 8.1, then discovered that networking for the virtual machines wouldn't work. Then I tried something incredibly simple and fixed the problem.

Checking the system I noticed that three VMware Windows services weren't running; VMnetDHCP, VMUSBArbService, and VMwareNatService. VMware Player allows you to install, remove, or fix an existing installation. I chose to try fixing the installation, and that fixed the problem. The services were re-installed/restarted, and the virtual machines had networking again.

Once network connectivity was established there was exactly one updated file for Ubuntu 13.10, a data file. This underscores how solid and finished the release was this time. Every other version of every other Linux installation I've ever dealt with has always been succeeded by boatloads of updates after the initial installation. But not this time.

Everything is working properly on my notebook. All's right with the world.

sony's pivotal mirrorless move

I'm a died-in-the-wool technologist, even when it comes to photography. I have always been fascinated with the technology that goes into manufacturing any camera, from the lenses (optics) through the mechanical construction, the electronics involved, and especially the chemistry of the film and the sophistication of the digital sensor. It's amazing that the camera can do all it's asked of it, regardless of manufacturer.

Of all the types of cameras that I've really taken an interest in, contemporary mirrorless (again, regardless of manufacturer) are the most interesting because of the challenging problems the scientists and engineers have had to solve in order to build a compact but highly functional camera. In particular I've followed the sensor advances over the years and watched image quality climb (especially with μ4:3rds) to exceed film and rival one another such that there's very little difference any more as you move from the smaller sensors such as 4:3r…
