The main reason I always turn to finite differences is because the formula are so easy that I can get it right the first time without looking anything up. But the cancelation problems are very real, so I might have to look into this, becaus

The fear is that the nuclear weapons sitting in storage are assumed to be functional, but might turn out not to be. This could have dangerous geopolitical consequences. We can study how the materials age, but have to use simulation to under

Not really. The equipment to seal wells and pipelines against leaks would cost billions. We need more generation, but solar is already cheaper than new natural gas built on the leaky network. It makes more economic sense to just overbuild y

Your first point is not supported by the data. The US Energy Information Agency keeps track of this[1], and the per capita energy use peaked around 2000. And we are much better at running an energy-efficient economy: energy use/real $

I know of two examples from the Depression. In Germany, it was a deliberate policy. In France, it was a zealous adherence to the gold standard. I am also bewildered. So many bad effects of deflation.

Do you mean fiscal policy? You absolutely can infuse trillions of dollars into the economy without causing inflation after the economy takes a $4T hit from a pandemic; the government spending will be what prevents disastrous deflation. Peop

I strongly agree with your last sentence, but the issue goes beyond operand order: the addressing syntax for AT&T is nigh incomprehensible to me.

So ~5T/person/year, let's plug in the Starship launch costs: at $1mn/T, this is only $500mn/year for the whole base. This seems a little too good to be true.

You seem to be right that the Jaguar is a poor car for road trips. A Hyundai Ioniq 5 will charge in half the time as a Jaguar I-Pace, and the car costs about a third less. https://pod-point.com/guides/vehicles/hyun

Requirements for an accounting system? That’d be hilarious if I wasn’t so traumatized by past experience. Seriously, the tensor product of jurisdictions, clients, strategies, and the various preferences of your rotating bosses—it’s a cascad

Different architectures have their own function passing convention. It’s convenient to evaluate left-to-right, pushing as you go, if that matches the arch. And vice versa.

Agreed. This code just looks weird to me. Throwing from a constructor? Holding the result of new() in a temporary? This is just asking for trouble. Another favorite “criticism” I have of C++ goes along the lines of “but someone could overlo

I think an unscrupulous developer would find 10% of $275mn to be a pretty big incentive. Sure it’s relatively less, but still a very large number.

Actually, I speak as someone who has lost a fair bit of money on algorithmic trading. The pattern I’ve observed is consistent, small gains punctuated by sizable losses. That was in a big market, but if the market segment is small enough, th

It’s “Wildcat Banks,” with additional regulatory risk. Crypto in the form of Bitcoin is not systemically risky. Crypto in the form of “stable coins,” which are actually shadow banks, is risky.

Your quote proves my point that Keynesians are the opposite of “statists” when he talks about “technique, taste, population and institutions” driving investment decisions. That’s what I want to see in my economy. Do you disagree with that?

Not sure what the scope of your sarcasm covers. But there is no such person as a “Keynesian statist” outside a crypto subreddit. Only a little part of Keynesianism involves the state, if you take a conventional definition of the theory. The

Second this. Even in the most bike- or pedestrian-friendly neighborhood of Minneapolis, all of the near miss experiences I’ve had have been because of driver inattentiveness. Is there some tautology here—with truck drivers and pedestrians f

Reads like it was written by someone who reads many inflation “truthers,” but is too empirical to believe the hype. Correctly rejects the asset-price inflation theories, which hold that the stock market, Bitcoin, and fine art appreciations

The short height is a serious problem. I think we can make some conclusions about the power output for a given material input. Based on the the images, my assumptions are: 100m mast and 80m blades; for the vertical turbines, a radius of 50m

Container ships are massive emitters of some pollutants like SO2, but not CO2. Sources usually put the carbon number at around 3%.[1] this number has been rising in part because the denominator, global carbon emissions, has been falling as

I agree with a lot of this VW seems to have done the “let’s rethink everything,” but much less successfully than Tesla. Not surprising giving their generations-long corporate legacy. I’m kinda interested in the Nissan Arya, because it looks

Batteries are quite likely to continue to decrease.[1] Most industrial processes follow a learning curve inverse to the cumulative units produced. And it makes sense: each efficiency improvement has a fixed cost, and only gets made if enoug

And vaccine escape is non-binary as well. Variants able to do that may displace other variants, but be unable to push R0 over 1 in a largely vaccinated population. The "South African" variant B1351 can break through Pfizer, but it

This comes up every now and again, and it's always just as meaningless. This current attempt to unmask the government's attempt to hide the real inflation is insinuating that the official statistics were changed to hide the realit

The US has administered 250 million shots, of which 7 million were J&J. These numbers, and the fact that the mRNA started trials earlier makes me proportionately less worried about surprise side effects for the mRNA shots. https:/

We’ve given the mRNA vaccines to enough people to be highly confident that your fears are ungrounded. The mRNA doesn’t linger more than a few hours. People received the vaccine a year ago.
