Electric vehicles are more heavily subsidized in China than America. 22% of new car sales in China are electric vs 1% in America. China also has a lot of tariffs and regulations preventing foreign competition.
You don't need a monte carlo simulation if you have a known distribution. You can just add the means and variances and solve the equation rather than approximating it with a simulation. Monte carlo is more useful when drawing from an unknown distribution.
Re:MIT-designed project achieves major advance toward fusion energy on Wednesday September 08, 2021 @09:03PM (#28465017)
Even if we can get fusion to work, it will never be economical. Just because the fuel (water) is free, that doesn't make the energy free. The fuel rods for fission power plants are already a rounding error in the cost of energy. It's the capital costs that dominate the equation, and fusion plants will be at least as expensive as fission, which is more expensive per KWh than solar.

Re:Triton: Open-Source GPU Programming for Neural Networks on Wednesday July 28, 2021 @05:44PM (#27990129)
> CPUs and AMD GPUs are not supported at the moment, but we welcome community contributions aimed at addressing this limitation.

That's disappointing. My biggest frustration is that every ML library (Pytorch, Keras, etc) is tied to CUDA/Nvidia, so I take a huge performance hit when running them on my Mac.

They used an overly simplistic computer simulation and programmed it to get their assumptions back as outputs. Luck may play a large role in wealth, but this study did nothing to prove that.

I'm working on a robot that can make noodle-based dishes by itself in a food truck. The end goal is to just do a bit of prep work in the morning, turn it on and leave it running all day to sell food in Seattle.

How to Measure Anything, by Douglas W. Hubbard.

When he says anything, he means anything. How to measure the value of a human life, how to estimate things you know nothing about (like the gestation period of an African elephant), and how to get better at measuring things with limited information.

There's too many possibilities. You need a narrow field of options for graphical programming to work. Blueprints works for Unreal because it is focused only on video games. https://docs.unrealengine.com/en-us/Engine/Blueprints
Re:Vegetarian diets are not going to save the planet on Thursday January 26, 2017 @07:11AM (#13490671)
Most of the arguments are just an appeal to nature. Doesn't address cow burps as a major source of pollution. Seems to be making a food miles argument, when what matters is carbon per pound of food. Transporting by boat is highly efficient and a high percentage of the cargo is food. Driving to pick up your food from 3 farmer's markets can create more pollution than would be used to transport them from across the world, because the food is such a small percentage of the weight of your car.

Urban planner. I'd love to try to create my version of a utopian city (no non-essential vehicles allowed, built for the pedestrian/cyclist/subway) the way they are building new cities in China or Dubai.
Re:Germany sees 'overwhelming' sales of Hitler's Mein Kampf on Tuesday January 03, 2017 @08:08PM (#13314840)
I just finished reading "Mein Kampf" last month. It's not very good. It's about 20% racist rants. He talks about some legitimate grievances German had at the time and from their history, and military strategy. I didn't walk away feeling like Hitler was brilliant or anything like I did with Trotsky after reading "Terrorism and Communism".
This is a prototype to test the Multi, a maglev elevator concept announced a little over a year ago. https://www.youtube.com/watch?v=KUa8M0H9J5o
The virtual DOM isn't a replacement for the DOM, it's just a string diffing algorithm. It is only needed because of React's "render everywhere" approach, which is a tradeoff sacrificing efficiency for simplicity. If you don't re-render the entire page any time the model changes, you don't need a virtual DOM.
