Oh, sorry, you're right, I confused TW with GW.

I used the data from: https://www.world-nuclear.org/information-library/country-pr... which dates from 2019, and has become worse than the data from wikipedia that dates from 2009.

135 GW is the total electricity production in France in 2009. Of which 80.1% were from nuclear power, or 108 GW.

The situation has worsened, nowadays we only have 70% of nuclear power, ie. 61 GW.

This is only the power installed. In terms of energy produced, it's even worse. At least, the 61 GW can produce almost 24h/24h ie. 1464 GWh of energy, while the solar panels work at best half the time, and actually much less, and a lot of their energy is also lost in the transformation required (storage in battery, building and recycling the batteries, etc). That may be acceptable for mobile applications, but to power factories, or static computers, this is a waste.

But my point is that is far from enough to replace carbon based energies, and that we're too late to build the number of nuclear plant that would be needed world wide.

What a joke!

France has 61 TW of nuclear power, and this covers only 35% of only France energy needs!!!

Imagine how much more solar installations will be needed to cover the energy needs of the world!

They would make a link between StudiO and Apple Watch (Health app). That would be an important part of the marketing. And then, they would expand to all other groceries. You'd buy or order your food from Apple Stores (or perhaps, Apple Groceries).

Yeah, it's called capital gathering. Without this war chestnut, Apple wouldn't have existed.

Assuming a Mars colony is established over then next 40 years, and assuming it won't be entirely independent from Earth, my guess is that a new calendar will have to be established, that will be independent of any planet, of any specific planetary cycle (diurne, yearly, seasonal). A kind of stardate?

The point is that the current worldwide energy consumption is 4.3 % nuclear, 6.9 % hydro, and all the rest is hydrocarbons.

To stop consuming hydrocarbons, we'd have to multiply the nuclear plants by 21.

There's a difference between the energy supply and the final energy consumption because of loses in conversion and transport, but let's assume that 100% nuclear energy reduces them and we need 150000 TWh total, so we need 95% of that in new nuclear power plants: 142500 TWh. 1 nuclear power plant produces about 1 GW and there are about 8000 hours a year. that's 8 TWh per nuclear power plant. So we need to build 17812 nuclear power plants. (And it takes between 5 and 10 years to build a nuclear power plant).

Now have fun: compute how many nuclear engineers, architects, and technicians do we need to build those nuclear power plants, and then to use and maintain them, build new ones when needs increase, and then to renew them; and the compute how much time you need to raise and educate these engineers, and cry on how much time is spent on "women's studies, gender studies, anti white male patriarchy studies" and bullshit like this.

Now take the problem the other way: how many people would 5% nuclear power plant support? Well, 5% of the population. ie. 400 million. Then you understand why https://en.wikipedia.org/wiki/Georgia_Guidestones, or you understand why no more than 5% of our energy is nuclear power?

But is CO2 so much of a problem? More CO2 means more green plants, means more food, means more animals and humans will be able to live on Earth! Before the coming ice age, anyways.

That's not so easy. For example Elon said that SpaceX could send people to Mars for $500k, and that he wanted to send 1 million people to colonise Mars. But also, using 1000 SpaceShips @ 100 people each, doing 10 travels. Well, if SpaceX makes 10% profit on that, that's a nice profit of $50 billion profit for SpaceX, (half a trillion of turnover), but over a period of 35 years, so $1.4 billion a year of profit. Is that enough to make it a multi-trillion dollar company? Is that soon?

IMO, 1 million people is not enough to make a self-sustennable colony on Mars, because it'll need to reproduce a whole industrial system to maintain itself. Perhaps with AI and robots it could be done, but will AI and robots be sufficiently advanced in 35 years to maintain themselves, and go mining and milling and repairing themselves and building their replacement, let alone doing all that is needed to sustain the life of 1 million people, even with their help? And how does this makes SpaceX a $trillion company?

IMO the real 4- and 5-comma companies won't be the companies that will take stuff off Earth, and probably not companies that will bring stuff from space down to Earth (because this market will be the limited Earth market, which is billion-sized). No, it will come from companies that will take raw stuff from space, and refine it and produce end-products in space, notably big stuff, like big space ships, and space-stations (habitats). Eventually they will compete with all industry and agriculture on Earth, and eat that market, but it will be but a drop in the ocean of the market in space. And their valuation will be automatically in the 4-comma, because of the cost to bring stuff to LEO from Earth, if we had to do it, even if Elon could bring the cost of that to very cheap. (give the mass of a space habitat, or of space farms able to feed the Earthlings and the Spacemen).

But people at SpaceX are smart, they're already doing money "in-space" (with the StarLink satellites), and they'll be sufficiently advanced to be amongst the first companies to fork pure space companies. And with headquarters on Mars, they won't have to pay taxes to Earth ;-)

I wonder how do they check all those digits are exact? Do they compute it two or more different ways? It is not possible to design a physical test for that precision. But even mathematically, if there's an error in the middle of the digits, what test can we perform to detect it?

The question, is what do they wait before merging with NVIDIA Holodeck?

Of course. Any tourism is a waste! Let's forbid people to move outside of their village! And by the way, capitalist stores like: https://tinyurl.com/live-store are a waste too, imagine the CO2 to produce all that paint and ink, and to do the marketing, when all you need is one bottle of milk and one biscuit and one kipper. https://tinyurl.com/bland-store

Also, gizmodo.com is a waste. We could do as well with facebook. We don't need hundreds of web sites, just one centralized and well censored web site is enough.

Hmm. Lava lamps don't seem random to me. They're macroscopic processes. Randomness exist at the brownian movement scale, but macroscopically, the movements and timings must be rather deterministic or at least statistically very constrained.

The Reader's Digest published several stories of airmen who fell from more than 5000 feet without a parachute (it had burned in the plane), and survived with no significant injury, during WWII. Clearly parachutes are not that useful.

Even more troubling than Aliens, Russians or Chineses, would be if those devices were NAZI UFO, or worse, non-homo-sapiens-sapiens devices (say, remnants of some ancient civilisation that lives hidden on (in) Earth.

Classic "1984" rewriting.

This is rather idiotic to petition for that. This is what will happen anyways. As soon as life in large space stations will be possible, billionaires will go up and stay living there all or most of the time. Trillions will be made in space. They will go up and not looking back.

This is how BCC works!!!

BCC = Blind Carbon Copy = you don't see that you (or another BCC recipient) is a recipent. Your address is not written on the letter, only on the envelope (ie. given to the MTA).

Also, the pro for Tennis and Boomerang is if the drone comes closer, you can directly hit it with the racket or the boomerang, while trying to hit it with balls or an arrow wouldn't be as effective.

That code wasn't the basis for unicode, where the mentioned characters have different offset in the common Chinese plane:

(map 'list (lambda (c) (- (char-code c) #x4e00)) "你他我") --> (352 214 5137)

But then, unicode has 20902 ideograms in that plane, while this typewriter had a shorter selection of 5400 ideograms.

I would design the batteries element with little robotic legs, so that when a thermal runaway occurs, they would disassemble and run away dispersing from the hot elements, to cool down each individually. </me mode="overengineering">

DUH!

Alternatively, turn it into an IRC feed. irc://irc.freenode.org/#hn https://github.com/informatimago/lisp/tree/master/small-cl-p...

How long it would have taken to use a fucking compiler generating buffer overflow checks when compiling sudo and other unix tools?

What a bunch of fuckers! "They haven’t disclosed when they plan to unveil the Vision EQXX electric prototype."

Not even a commercial product, a prototype, and they don't know when they'll be able to show it!

What they've been doing for a hundred of years!

I'll buy a Tesla.

Yes. World IQ is dropping fast.

The contest will be won by the person using a robot finger on an old spare iPhone, able to provide the longest continuous support (power, internet, etc). The contest would last months if not years. Uptimes for computers are in tens of years, but for iOS system, one year might be a maximum. Uptime for lego robots may be much shorter, but uptimes for professional test robots are probably much higher. So I'd bet for some idle professional test robot. (electricity bill and hardware amortisement would largely allow it).

Knowing that, only people with such finger robots available to them (or able to build one) should participate, and the organiser would lose the price.

The fact that he won't is proof of the lowering IQ in the world and that he's an immoral scammer (but we already knew that)... :-(

Asimov's laws are only good for a lifetime writing career in exploring their exceptions. Is there any Asimov story where the laws were applied strictly and successfully? I don't remember one.

COVID-19 is just an excuse.

There's a vending machine in my building.

It works full regime during lock-downs. Well, as long as they can resupply it!
