Back to Cuba.

Since I, and others have said it is time to 'Move On'. With our Diplomatic and Economic Relationship with Cuba.

Can the Present Cuban Government allow truly Free Trade. Including the Exchange of Ideas they don't agree with.

Or would they consider the above to be destructive to their power.

Give it some time. Raul is not young, and the people have had a taste of a better life. This won't happen over night, but I think it will happen.
The seeds are sown, and hopefully they won't be un-sown.
I think that over the next decade, Cuba will go through a lot of changes for the better.

The difference is that other than a few reckless small attacks, Kim has not tried to invade anywhere.
Hitler did.
Hitler had ambition, Kim just wants to survive in his leadership role.
They are both horrible men, and negotiating may be worthless.
It has proven to be so far.

Perhaps another idea. How about we give them a significant amount of aid, and encourage China to do the same.
Find a way to breach their society, which is closed. I know small efforts are already in place. Flash drives are being smuggled in and out of NK, with even just movies from the outside world.
I realize that aid would not go to the people who need it, as Kim must keep them weak.

I would really hate to see an all out war, where millions could die. Tokyo has I think 13 million people in it, and if just one nuke missile landed there, we have an instant disaster.
If China does get drawn into a US NK war, the consequences would be beyond anything this country has ever experienced. Wrecked infrastructure, food, water, power, transportation shortages would be just the start.

Post:
What about direct dialog with Kim and the US.
It is true that Kim has gone back of the agreements made previously, so this is not perfect.
One of his goals is assurances the US won't attack him.
Their reason for existence is always having an enemy to defend against.
They ratchet up the treats, then back off. This repeats.
I don't think their intent was to start a war they can not win, but only prepare for one.
It might just work out, that if the US could no longer be considered an enemy, then the regime may collapse over time.

Disclaimer: I really have no idea what the best solution is.

The problem with stopping Kim from causing harm by force, may cause the death and untold suffering of millions. I would not want to be living in South Korea or Japan if we decided to stop the violence against others.

Polytheism, or belief in many Gods was not about morals, but appeasement and sacrifice.
People thought that if they performed some particular act, the Gods would favor them, and let them win battles, or let their crops grow.

When that evolved into monotheism, morals were introduced for the first time. It became less of appeasement, and more of doing what each religious branch determined to be right. That began a time for a very divisive climate in human history. Many millions people were slaughtered as the different factions struggled for superiority. I seem to remember some 400 million died just as a result of Christianity.

The human animal has been in its current form about 200,000 years. The development of religions is fairly recent. There is scant information prior to 10,000 years, but most of what is believed today is just a couple thousand years old. I wonder where we will be in a couple of thousand more years, if we still exist.

William's right. It is far easier to just detect a signal from an intelligent source, than to worry about what it says.
Suppose aliens about 50 light years out are just detecting I Love Lucy.
Most likely all they would recognize is a signal coming from somewhere near our sun that was not natural.

Byron, you are a beautiful person.

I am certainly not free of flashes of anger, fearful reactions or periods of despair.

I hope to live up to your words some day...


I ditto that.

I love European beers, but Budweiser is inexpensive, and my system is used to it. My favorite beers are the Trappist Ales. I have been drinking Budweiser for decades. Some of the American craft beers are very good. Every now and then I stumble on a good one.

I am enjoying some Budweisers, and a 8 swallow swig of 100 proof legal moonshine while cooking pork chops, green beans, and bread sticks.
My wife is having a baked potato in addition to the above, except no alcohol.

That sounds excellent! It's hard to imagine so much mass could make up one object.

Yes. Running it slower keeps it in the radiators longer, but it quickly exits the GPU's. With the chiller CPU loop, the added electricity and size of the chiller tips the balance.
I started with a much stronger pump, and learned that too much power, just added heat. Slow down the coolant flow, but don't stop it. Don't let the heat from the pump add to the coolant temperature.

The trick, is to make the coolant stay in the cooling region as long as possible, but keep it in the heating region as short as possible. That way more heat is dispersed than collected. It's all physics.

Steve

Of course equilibrium is reached. The greater the cooling surface, the lower the resultant temperature.

Do you use the pump to move the water or just gravity heat?

I use two separate 10 watt pumps. One for each loop. Any greater than 10 watts, generates heat for the loop.
The fans are set to pull air through the radiator. Pushing air adds the fan heat. It's all engineering.

When properly designed and implemented, water cooling is unstoppable.
I have been using it for years, without leaks. My system is made up of two separate cooling loops.
One is for both GPU's, and consists of 2, four 140 mm fan radiators. Each GPU loop is cooled with a radiator just before it hits the GPU.

The second is the CPU cooler, which runs through a 1/2 hp aquarium chiller. My current fluid temp is set for 50°F, which means with a 4.4 GHz clock speed, my CPU temps are only 49°C. My GPU's, massively overclocked, never get above 60°C. Right now, they are less than 55°C. I am ramping up for the latest challenge.

These are old GPU's, but at some point I will modernize them, but will keep the same cooling system.
Because of the fans and chiller, this is not a silent system, but it is impervious to overheating.
