Lights and switches using radar have been around for a long time. Human presence radar detector switches are common in car seats. Light bulbs that turn on using microwave radar to detection human presence are cheap on eBay: https:/&

It is very obvious that people go crazy every Spring. They get out in the sunlight, which makes them feel better after a vitamin D deprived Winter. Life is less difficult than when snow was around. People in high spirits get playful. Th

I think Krugman is missing something here, with both electrification and computers/IT many new devices and software and interfaces had to be created from scratch for people to be able to use them, and people had to learn how to use the

A lot of people talk about what ChatGPT does. Few seem to talk about the data it was trained on. That data came from us, from people. So besides the algorithm, there is the training which is...what precisely? Everything on the web? Sci

One thing we do know, it is Congress that tasks the USA intelligence services, as well as the President. Found this PDF on the web: https://www.cia.gov/resources/csi/books-monographs/the-agenc... which seems

A nice summary of what is wrong with economics in general, why it isn't a real science yet. It also explains why a lot of financial people have been freaking out since the pandemic started, their models don't work anymore but the

Now on to the rest of the problems with Amazon's web site. Do a search on "canned shrimp" and then select "Sort by: Avg. Customer Review". I see seven pages of results, none of which include any canned shrimp even

Maybe that's a solution to the war in Ukraine. Give them a few nukes and Russia may back down. Risky though, it could prompt Russia to try to nuke Ukraine first.

I've often wondered what the old timers dumped in the woods around Boston where the United States started. They weren't only dumping stuff in the oceans. Seems like a radiological and toxilogical survey of the entire USA would b

This is the unit I was thinking of, 8000BTU cooling, 7000 BTU heating via heat pump, plus some supplemental resistive heating: https://www.amazon.com/dp/B00L4RLMNM Only one available from a 3rd party for $1700!

Would be nice if some company started making window heat pumps that are more efficient and do heating as well as cooling to replace window air conditioners. I've read of one company that makes them but they never seem to be available

I would imagine anything related to US infrastructure of all kinds is going to be funded soon due to the $1 trillion infrastructure bill.

If there is a major breach it seems likely that it is going to become known in time, whether it is reported or not. Not reporting it gets the company in even worse trouble. Principal agents do not avoid legal liability by changing jobs.

I often keep commented out wrong code with an explanation of what is wrong with it in the comment. But most of the code I've written is experimental, often involving reverse engineering black box systems so they can be used in unconve

I second this, though I haven't tried the alternatives which I hear are also good. There is some value to specific kinds of pitch shifters, like the Boss Octave pedal, the Digitech Whammy pedal, and Eventide's harmonizers. Depen

It seems logical that this is happening in a lot of places. Access to an AC outlet is not controlled at all in most buildings and anyone can plug in anything. A crypto miner with a loud fan might be more difficult to hide, but there are l

Think about what this means for Ukraine where shells from both sides all land on Ukraine soil. The current front line is going to be a disaster area for decades.
