Portugal has the kind of health care system that we could have here, if we chose to focus on people and their health outcomes rather corporate profits.

Buy everybody a battery. 10.09.2023
Green Mountain Power in Vermont is taking a novel approach to improving grid reliability — they propase to pay to have big batteries installed into most homes. The company says that this would be cheaper than building more power plants and stringing up more wires.
All Electronics is going out of business. 09.11.2023
How sad. They were in business for over 50 years, but it looks like they are retiring. I bought many parts from them over the years. They specialized in reselling parts — buying up unused lots of random things and selling them at a discount. So, they were never like DigiKey or Mouser, in that they didn't try to stock everything. They had what they had, and if you wanted one of what they had, you could get it at a good price.
I did a fair amount of business at All Electronics. I sent them many dollars over the years, but in the end I came out ahead. Through circumstances that I won't try to describe here, I once found a box filled with about 3000 new PCB-mount relays, similar to these, in a dumpster. Looking up the price of these relays on DigiKey suggested that they were worth about $7000 retail. I'd struck it rich! I called up All Electronics (and a couple of other places) to see what they would give me for these relays. All Electronics won the deal by offering me $700. That's how they rolled, by paying about ten cents on the dollar for their stock. I took the deal and still considered myself lucky.
All Electronics is closing their web site for good tomorrow (Tuesday) at the end of the day. If you hurry, you can probably pick up some DC wall supplies, or a handful of bridge rectifiers, or a bag of LEDs for cheap.
Top programming languages. 09.07.2023
IEEE Spectrum is out with their annual ranking of programming. It is a complete mystery as to what the numbers actually mean, but the general ordering "seems" about right.
Super blue moon. 08.30.2023
The full moon tonight is a "super blue moon". It sounds impressive, but really not that big of a deal. It's definitely not blue — the designation is a vagary of the particular calendar we use. And it is hardly super — the moon is a bit closer to the earth and so appears to be slightly bigger and brighter than "normal". However, a full moon coming over the horizon is still an awesome sight and worth of few minutes of watching time. (Maybe werewolves have bigger and sharper teeth or howl louder during a super blue moon. 🐺🤷🏻)
