As I Used to Say at Work…

… “let’s swap all the tires until we find the flat one.” With “tires” being an expression for whatever the not obvious cause was of a technical problem.

That’s the situation I’m in right now. The power company sent a notice yesterday, warning of possible outages, due to high wind. So, I wasn’t surprised this morning to see there had been two of them. But then I saw that the router was offline.

Power was off, not only in the office, but throughout the finished half of the basement. Checking the power panels in the unfinished half, it was easy to see that one of the circuit breakers had popped. Resetting it once, twice, three times, didn’t work. So, something must have shorted out due to a power surge.

The first thing to do was see if Internet service could be restored. With a very long extension cord, I connected the office gear to a test outlet next to the panel. Success! That put me back online. Would the circuit breaker still refuse to reset?

Yes, it did. So, where’s the problem? I disconnected everything else, and tested the breaker again. It held! Yay!

Now the question is, what shorted out? I’ll test each outlet and, assuming they’re all good, reconnect everything one by one, to see what pops the breaker. But not right now, because I have a dentist appointment to fix this damn broken tooth.

Bluestooth

For something that was intended to be simple, Bluetooth audio presents some difficult challenges. The one device I have that doesn’t give me trouble with Bluetooth audio is a lowly Amazon Fire HD10 tablet I bought a few years ago for $75.

Windows has never displayed the Bluetooth audio codec that it negotiates with another device, let alone provide an option to select a preference. My Sony Bluetooth speaker supports AAC and aptX, in addition to the required SBC codec. Windows 10 supported Qualcomm’s aptX audio, but Windows 11 doesn’t.

When playing videos, my Dell laptop PC with a Qualcomm arm64 processor has a significant audio sync problem with my Sony Bluetooth speaker. Because Windows 11 doesn’t support aptX, I have to assume it’s resorting to AAC. That must have also been happening with the Lenovo laptop that has since been moved downstairs. I don’t know why its Intel i7 x64 architecture doesn’t have the Bluetooth AAC sync problem.

I put a cheap Bluetooth adapter on the aux port of the Sony speaker. It supports only SBC, and there was no sync problem. I would have continued using the adapter, but Windows has a nasty habit of disconnecting connections that are idle. The Sony speaker has a switch in back that keeps its side of the connection open, even when there’s no audio stream. Occasionally it fails, probably due to Windows refusing reconnection, but it usually works.

So, what I wanted was the ability to select SBC and, ideally, Qualcomm aptX within Windows 11. It’s ironic aptX doesn’t work, considering the laptop is running a Qualcomm Snapdragon Plus processor.

Bluetooth Goodies to the rescue.

I asked about support for arm64 and added an e-mail address to their mailing list. I must not have been the only one asking about Windows on arm64, because soon afterward there was a beta version of a driver to try. While I was in the process of confirming it did what I wanted it to do, a WiFi problem came up. I’m not certain it was related, but I removed the driver anyway, by returning to a system restore point I had set.

Later, Bluetooth Goodies said a release version of the driver was available. I installed it and, so far, it’s been okay. The connection is using aptX, and there is no audio sync mismatch. If nothing comes up before the end of the trial period I’ll buy a license.

Plasma Partisans Unite!

Food isn’t the only thing that can be overly processed. I was surprised and pleased to hear this segment on Marketplace, about the “improvements” that are found in the latest televisions.

Computer monitors continue to “look correct,” but television technology is going in the wrong direction, as far as I’m concerned. 8K? Really? But is returning to the old, discontinued plasma technology the best way to go? For some, but not for me.

A couple of friends have plasma TV’s (you know who you are!). They continue to use them and are pleased with the picture quality. I once tried a plasma TV, but for whatever reason, my eyes with cataract replacement lenses had trouble with it, as I explained at the time.

Plasmatic reaction

This video shows the effect of phosphor lag that, I suspect, some models of plasma TVs had more than others.

I see HDR (high dynamic range) as being another industry misstep, like 3D TV was. The idea seems to be that too bright isn’t bright enough. As I have said multiple times, I am happily hanging in with my two Samsung LCD/CFL sets and my very beloved JVC video projector. No HDR, no 3D, no motion smoothing, and no built-in “intelligence.”

P0420

My 2011 Honda CR-V has 82,000 miles on it. The check engine light came on six months ago. As the weather warmed up the light turned off and the car passed the emissions test during annual inspection.

Recently, with the weather turning colder, the light returned, and it has stayed on. I bought one of these for $17:

The OBD II scanner reported this:

P0420 $f111
Catalyst System Efficiency
Below Threshold Bank 1

So, it would seem the catalytic converter is failing. I reset the code to turn off the check engine light, but it’s certain to return.

I bought the CR-V new, fifteen years ago this coming May. In Massachusetts, a 15-year-old car is exempt from emissions tests. What to do… what to do…

A ChatGPT for Medicine

Wall St. Week recently featured the medical information startup OpenEvidence.

If this outfit goes public, it will be the first time I buy stock in a company other than my former employer, which is privately held.
