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

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 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 cance

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.

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 cas

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

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

(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

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 com

Work on this, but you let obvious frauds like Magnegas stay on the exchanges for decades.

How much will they weigh compared to a Diesel bus? Road damage is to the fourth power of axle weight. Any cost savings may be just shifted to the road department for fixing pot holes. I think the VW EV is almost twice the weight of a

I'm sorry. The U.S. is broke. How about trading with the Bear instead of poking at it? U.S. Russia isolation policy has failed miserably.

I worked for Cray Research in the 1980s. A lot of the CAD software for the Cray 2 ran on a Z80 based CPM machine called the Intertec Suberbrain. Then we got a bunch of PCs from ATT called the ATT 6300 (Actually made by Olivetti). We fig

I believe that the Cray-2 used 3M fluids (flourinert) for liquid immersion cooling when it was introduced in 1985. It was in several data centers including one at Lawrence Livermore Labs. It was not something invented by crypto currency
