By the time the Cray-1 was designed, Seymour Crays children where in college. This might have applied to when he was designing the CDC 6600 when the children were younger. I know this because the Cray kids were a couple years ahead of me in high school. There are a lot of stories like this put out by John Rollwagen to build up Seymour's design creds.

You need to think of the cost of this kind of treatment at this stage as R&D. If it works thousands of people will benefit, have longer lives and contribute back more than the lifesaving treatment will cost.

States should stick to running a state patrol, maybe a university or two and a court system. Otherwise, stay out of peoples way. Don't collect huge bribes from cable providers to limit competition.

I dropped Dropbox when they put KindaSleezy Rice on their board.

I have one firm rule these days. No rent seeking behaviors. This avoids talking to phone centers in India or some other foreign country, where the person on the other end of the phone barely speaks English to try to get the service cancelled or to fight aggressive billing.

When they said there were thousands of derailments each year in the U.S. i found a source on the internet that said the total for all derailments in Japan in 2020 was a grand total of 6.

Not to mention how these heavyweights will crush the hell out of our highways. Road damage is to the 4th power of axle weight. Will a fleet of electric cars and trucks we will be spending a huge amount on new concrete and tar. Both are significant CO2 sources.

Maritime Law had a provision for salvors that saved ships in distress from sinking. If a salvor saved a ship from sinking, they were entitled to a percentage of the worth of a ship. Maybe terrestrial law needs something similar in the case of uninsured building on fire.

Look on Hackaday for "Why do you need to use decoupling caps". I am not seeing any talk of decoupling caps in any of this persons writeups. Maybe they are there and I am just not seeing them. It used to be when designing with LS ttl you needed one per chip to make sure switching noise did not get onto your power supply rails. Otherwise, a great project for learning.

University of Minnesota hospitals have developed a method of doing Fecal Transplant using freeze dried pill that can be taken orally. I'm looking for someone to make a sample high in prevetella stecoria that has benefits for prostate cancer patients.

According to Wikipedia, California has 5-7 billion barrels of oil in untapped fields in their coastal waters. Some can be tapped using existing wells offshore or onshore wells using directional drilling. This is 10x what is in a full US petroleum reserve. Maybe tapping these would go a long way to lowering prices?

(4000/3500)^4 = 1.70 so that 70% more road damage with a fleet of EVs. I don't know how high Vehicle Registration is in your state, and Fuel Tax, but it does add up to a surprising amount that mostly goes into rebuilding highway infrastructure. So it does need to be accounted for. Our transportation highway network is a system. ]

The environmentalists killed a zinc mine in my state due to pollution concerns. Of course every pound of zinc not mined meant more steel without zinc protection, and hence more rust and more mining of iron ore. Arguments like this were completely lost on them.
