I see this as an already solved problem. Dr. Isaac Asimov wrote a series of robot novels that stated and explored the Three Laws of Robotics: 1: A robot may not injure a human being or, through inaction, allow a human being to come to harm. 2: A robot must obey the orders given it by human beings except where such orders would conflict with the First Law. 3: A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. And the Zeroth Law : A robot may not injure humanity or, through inaction, allow humanity to come to harm. For those of you who haven't read the novels: https://en.wikipedia.org/wiki/...

I replaced the keycaps on an old IBM model (M?). Keycaps and keyboards are out there. Do a search. May you find your input device of choice for the holiday season. Happy Festivus.

Also a ham, and Tesla model 3 owner. Went to meet another ham who was operating in the park (POTA) on 17 meters. On arrival, he commented on the interference caused before the car was even in sight. You might try listening again.

Yeah the SABRE reservation system, written to run on mainframes. IBM. You think American Airlines wrote the code?

So, nobody is mentioning they are Tesla's SolarCity panels? Gizmodo mentions the inverters on the panels.

The company, ... helps companies and governments investigate cyberattacks and online fraud, and has customers ranging from Interpol to Russian banks and defense companies.

So we can translate this as Group-IB providing information about hackers, to a target of Russian government hacking then?

Though it's a long way from becoming law, one of the legislators proposing it says "We need a paradigm shift in how we measure and evaluate our economy. If my district, New York's 16th...

Real "professional" journalism right here. Your quoting Jamaal Bowman, but not identifying him? Disappointing...

Small nit: KE is not quadratic, it's squared. KE = 1/2 M V^2 Your numbers are correct though.

Indeed, seems like TDR (time domain refelectometry) to me. Closed circuit radar that shows the location of discontinuities.

You lefties are confused. If you would just leave services like deliveries to the private sector, you wouldn't have our tax dollars that prop up the USPS subsidizing Chinese delivery. Private business would fix the price or go out of business.

No confusion on this side of the education divide; USPS gets NO taxpayer funding. NONE. It's all paid for by postage.

You can also try using the

website which hosts links to about 150 (as I write this) individually owned receivers all over the world. Can be better reception from different locations.

Letter mail is OCRed to facilitate automated sorting. That orange barcode on the back of your mail links to the database record of the mailpiece destination. It's how the postal system sorts all that mail so quickly, with so few people. I've long suspected that the data got used in other ways, but it's primary purpose is to move the mail.
