How many notes per unit?

It may be a symptom of age that I looked at this album on iTunes Japan and thought, “Eldo is the better song, but Halo is over six minutes long for the same price!”

For what itʼs worth, Eldo costs 2¥ per second, while Halo costs a little over ½¥ per second. So Halo is clearly the better value, even though Eldo is more popular.

Disgusted with myself, I bought neither.

Donʼt sweat the details

Silicon Valley tech companies gotta Silicon Valley. Amirite?

Apple has a new version of its HomePod device available. Much like most of its previous devices, itʼs built for people who live in the greater San Francisco area, where the weather is largely placid, boring and uneventful. In other words — entirely unlike most of the rest of the planet.

The web page about the new HomePod includes this footnote about its temperature and humidity sensors:

Temperature and humidity sensing is optimized for indoor, domestic settings, when ambient temperatures are around 15°C to 30°C and relative humidity is around 30% to 70%.
https://www.apple.com/homepod-2nd-generation/#footnote-9

Well, 15°C is 59 degrees. How often do people let it get down to 59 degrees in their homes? All the time.

There is no shortage of basements in places like Green Bay, Minneapolis, and the entire nation of Canada where people have a basement that has been kitted out as a family room, or a den, or a home office and that remains unheated most of the year. One of Appleʼs scenarios for using the HomePod temperature sensor is that it can be paired with other HomeKit gear to automatically turn on a heater if it gets too cold. Great. Except that if your chosen temperature for activating the heat in your unused basement or attic rec room is below 59°, Apple admits itʼs not going to be reliable.

On the hot side, OK, itʼs unusual to have an indoor temperature above 86°. But Iʼve had it in my house many times when the humidity was low and I lived in the desert. Many days in the spring and fall when Iʼd have the windows wide open enjoying the warm breeze and low humidity, the indoor temperature would get to 86°. If the cat was sleeping, that was fine. Sheʼd eventually wake up and start complaining, and Iʼd have to close the windows and bring the temperature down to 80-ish for her. But thatʼs to be expected, since she wears a fur coat. If I didnʼt have the cat, Iʼd probably have the temperature higher. And Iʼm not alone. Thereʼs a reason millions of people retire to hot places.

The humidity range is oddly narrow, too. Iʼm sure that 30% humidity is bone-crackingly dry in Cupertino. In Nevada, itʼs a bit clammy. When I lived there, the outdoor humidity reported by the National Weather Service was regularly in the single digits. And both of my indoor humidity sensors almost always showed readings well below 30%. Both of them appeared to have the same sensor under the hood, since they both stopped reporting humidity at 10%. These werenʼt expensive high-tech scientific humidity sensors. One I bought at the Apple Store for about $100. The other came from the supermarket, and cost about ten bucks. But it was perfectly happy reporting humidity far lower than what Apple considers reliable for its equipment.

Living in the Bay Area, Apple employees canʼt possible envision indoor humidity above 70%, but guess what — thatʼs a perfectly ordinary occurrence in most of the southern United States, including Florida, New Orleans, and Houston — the fourth-largest city in the nation. According to my HomeKit-connected humidity sensor, the humidity inside my house has been over 80% five times in the last two months.

All of this continues a pattern at Apple of designing products that only work well in the very specific, very ordinary weather conditions of Silicon Valley. Things like iPod headphone cords that get brittle in a Chicago winter, and iPhones that shut themselves off in temperatures that are common for millions of people who live in desert environments.

Apple has the money, the resources, and the people to do better. Why it chooses not to remains unclear.

♫ Chess nuts boasting in an open foyer ♫

MicroChess on a KIM Uno hooked up to a MacBook Pro

I almost beat a computer at chess today. Almost.

I've been playing chess against computers for four decades now, and have never beaten one. Not even once. Not even on “novice” levels. If a chess board had pieces more worthless and expendable than pawns, I would be one of those pieces.

But I keep playing. Atari 2600 Video Chess? Kicked my ass. Sargon Ⅱ on a Commodore 64? Took my lunch money and gave me a wedgie. Battle Chess on an IBM XT? Bought me flowers, took me to dinner, brought me home, kissed my hand and then didn't call me the next day.

Tonight I did something I have never done before: I managed to “check” a computer opponent.

The opponent was MicroChess on a KIM Uno, the modern-day incarnation of the old MOS KIM-1 machine.

The KIM did eventually beat me, but for once it wasn't the sort of Gulf War shock-and-awe defeat I'm used to.

I got the KIM because I nurse a fascination with the early days of computing, and because I found out that one can be built for under $20. That's another of my fascinations: Ultra-cheap computers.

My KIM Uno, happily letting me know that white pawn 0F moved from space 13 to space 33. I later housed it in a cardboard box

The KIM Uno is a good way to get a taste of what it was like to compute in 1976. But it's not a faithful reproduction. It's more like a tribute than a recreation. The KIM software runs on a miniature single board computer, and has been modified in ways that make a lot of concessions to the limitations of the Arduino side of its split personality.

There are a lot of web sites on the internet that talk about the Uno, but it's clear that the people who blog about this machine put the parts together, poked in about six instructions of 6502 assembly, and then moved on to other things. If they had stuck with the KIM Uno, there would be an extensive library of modern software available for it the way there is for other new models of old computers.

One sure sign that nobody has ever used a KIM Uno for anything other than a minor plaything is that nowhere on any of the web pages flogging it do the writers mention battery life. I surmise that none of them used it long enough for that to be a concern.

The Kim Uno's primary problem is that it lack expandability. One of the greatest assets of the original KIM-1 was that it could be expanded in many ways. You could add memory. Add storage devices. Add circuits and relays and printers and terminals and pretty much anything the hobbyist could imagine. The KIM Uno leans on the Arduino's built-in serial port, and that's about its only connectivity. But even that serial port is fixed at a speed and parameters that make it incompatible with a number of era-appropriate terminals.

There is an expansion port of sorts on the KIM Uno, but it isn't documented. There's a single picture on the internet of the KIM Uno driving a small OLED display, but no information about how to do that. And worse, the KIM Uno machine driving the display isn't even running the KIM-1 ROMs. It's being used to emulate a COSMAC ELF.

To summarize: unlike the KIM-1, the only thing the KIM Uno is good for is to play chess. But on the other hand, the KIM-1 cost the equivalent of $1,300 today dollars, while the KIM Uno can be had for less than $12 in parts. But with that reduction in price comes a reduction in possibilities. And the whole reason people got into computers in the 1970ʼs was because at the time, we thought the possibilities of technology were endless.

A screenshot of surveilance video on WGN-TV

This morning the big story on WGN-TV news was another mugging in Chicagoʼs Lincoln Park neighborhood, as illustrated by the screenshot above.

Why is yet another mugging in the nationʼs third-largest city a big news story? As a former television news producer, I can answer that.

  • Itʼs part of a series of muggings that appear to be caused by the same group of people.
  • It happened in a part of the city that is generally considered safe.
  • It happened in the middle of the day.
  • The mugger threatened to shoot the victimʼs dog.
  • There was video available of the crime.

I canʼt speak to what happened in the WGN-TV newsroom when this story was written. I can, however, state that if I had aired this story in any of the cities where I produced TV news — Chicago, Houston, Cincinnati, and even Green Bay — the newsroom would have gotten complaint calls from people claiming that the only reason we aired the story is because it happened in a “white” neighborhood.

This is incorrect.

While itʼs true that muggings happen all the time Chicago neighborhoods that are more “diverse” and impoverished than Lincoln Park, the reason this was a big story is because it was the intersection of the five factors listed above. And of all those factors, the last one is the most important: There was video.

Television is a visual medium. TV without pictures is called “radio.”

Lincoln Park is a rich neighborhood, which means more people can afford personal security cameras, which means more video of crime is available. Englewood, as a random example, is a poorer neighborhood, which means fewer people can afford personal security cameras. Therefore, thereʼs less video of crime from that area, and thus itʼs less likely to be the main story of the newscast, unless itʼs made into a larger piece with crime statistics and interviews with cops, politicians, criminologists, residents, and whoever else is available.

I canʼt count the number of times Iʼve had to weigh two news stories, and chose the lesser one simply because video was available. If the news program isnʼt visually compelling, itʼs an important factor in people tuning out, ratings going down, and the next thing you know, youʼre on the street.

Struggling to make important, but non-visual, stories more palatable to a television audience is the reason that TV stations put all kinds of text on the screen. A still picture with a caption over the anchorʼs shoulder. A list of bullet points on one side of the screen. Even putting text between two anchors sitting in front of a chroma wall. And sometimes all the visual tricks in the book canʼt make a non-visual story work on TV and Iʼve said, “Let radio have it.”

Race is often an easy answer to not understanding how things work, but in local news it is seldom the right answer.

On a side note, Iʼve noticed that reporters in Chicago now call muggings “robberies.” The common term for a mugging when I lived in Chicago was “strong-arm robbery.” Itʼs a very Chicago term with a long history. I suspect the problem is too many people working in Chicago TV who are not from Chicago, and not thoughtful enough to adopt the local customs.

It seems strange to me that when filling in your personal information on the Fortnum and Mason web site that the default telephone country code is +229. Thatʼs Benin, all the way in Africa.

It would make sense for the default country code to be +44, since itʼs a British department store. Or maybe the country codes could be sorted numerically, so itʼs easier to find the one youʼre looking for. Or perhaps use the country code of the customers who generate the most revenue for the store, whatever number that may be.

But I doubt that the people of Benin buy more F&M stuff than any other country.

Sunday, December 4th, 2022 Alive 18,849 days

It was a foggy, depressing day so I went out to Turtle Bayou where I knew there wouldnʼt be any other people; and there werenʼt.

I did find lots of birds, though. I recorded nine new species for my list:

  • Golden-crowned Kinglet
  • Purple Finch
  • Winter Wren
  • House Wren
  • American Pipit
  • Eastern Phoebe
  • Ruby-crowned Kinglet
  • American Goldfinch
  • Yellow-rumped Warbler

There was also a metric ass-ton of mosquitoes. But thatʼs OK; the birds have to eat, too.

I thought about it for a while, and I think itʼs probably been close to 30 years since I was last bitten by a mosquito.
