Before chips it was radio and radars. The Klystron was invented at Stanford. Lockheed Martin Space and Raytheon have locations in Silicon Valley.

The latter I would think. I can see how you can confuse the two. The reason I think otherwise is because you don't name the satellite after one client, especially if you're in the business of selling images/data, not satellit

Yeah I feel like China and their OSS model companies really did the world a great service by ensuring closed source US companies don't have an monopoly on LLMs and thus capture all the value of AI development and its impact on society.

Oh right! I got disk compression and QEMM and EMM386 all mixed together in my now decades old memory (pun kind of intended) of DOS to produce that false recollection.

Didn't DOS have it too?

Ideally when you declare something as technical debt, you should work to stop accumulating it. If possible, use AES-256 instead of AES-128 but you don't have to drop everything to switch to 256 today or even next 6 months.

"I have used more than a few systems with ECC UDIMMs and I recommend avoiding them if convenient as ECC UDIMMs are expensive on the second hand market while ECC RDIMMs can get very cheap." Boy did I learn that the hard way. I foun

I wonder if some of that can be attributed to automated trading systems that interpreted the news related to SpaceX and performed sentiment analysis and then traded based on that.

Hang on. City level officials play an incredibly important role in China. While Nanjing is not in the same tier as Shanghai, Beijing, or Shenzhen, it is in the tier just below them. It is the provincial capital of one of China's most i

Isn't the idea here to gasify the rock by essentially microwaving it? With ultrasound, wouldn't you still need to remove the leftover rocks?

Just one so far and it's not particularly small compared to a more conventional reactor. Russia actually does have a smallish SMR but it wasn't terribly cheap to build nor operate. IIRC it is in the form of a ship and used to powe

I know Microsoft tried it. They had a press release saying it was successful but never did it again. Does anyone know more about that? I agree with you that data centers in the ocean seem a better bet.

I've used this knot for almost 2 decades now since learning about it from this exact website. It looks really nice, easy to take apart on purpose, and has never come undone. I run 4 to 5 times a week and used to run marathons. That&#x2

Fair point but it's not social either. It's a new class of exploit that's based on tricking the AI.

The end especially. This really gave it away: "So can you stop a hypersonic? Sometimes, the wrong ones. Probably not the right ones, yet. The one defense working against the right ones today is a politician’s restraint, not a kill chai

Wait. You're missing something. Charging was what stopped me from getting an EV when I was a renter. In a world where I can recharge in 7 to 10 minutes, it becomes a lot more feasible for a renter to get an EV without at home charging

Yeah what as the story behind the BBerg take down drama? I just remember it being something absurd.

Just a dumb estimate. I'm just making an uneducated guess on what the car would cost if it was assembled using American labor with Chinese parts. I honestly don't know what the actual price would be. It's very possible for it

There's a non-zero possibility of that actually happening. It's already happening in Europe. Trump has mentioned the idea of a JV with Chinese companies. It is possible for this to happen in the upcoming Trump-Xi meeting. Chinese

And Tesla also receives subsidies from China because of their Shanghai gigafactory.

I would be OK if we tariff or effectively ban Chinese EVs (as is the case now) for a little while to give our auto industry time to retool and catch up. The current situation with a ban but no long term EV adoption plan in place is just inc

What I mean is that since the peak of American REE in the 1970s and 1980s(?) a lot of the engineers who have working knowledge are retired. There's nothing theoretical we can't dig up but I think there will need to be a number of

I think they do have a moat because they dominate the supply chain not just in the raw material and processing but also in some of the actual technical experience, i.e. the experience of running such processing facilities, and also a monop

Japan is also particularly well positioned because China had used rare earths against them first in 2014. Since then they've created basically a strategic rare earths reserve and done research on how to build some components without th

> People hold up China as an example but China was not displacing any local industry including its own. It's incredibly easy to do that because it's greenfield. Fast forward 20 to 30 years when new thinking might impact BYD or

> A sow will absolutely lay down on her piglets and suffocate them. This makes me really curious because that behavior seems very maladaptive for a species. That leads me to wonder if something else, ie. the environment or domestication,

This is exactly how effective censorship works. For example, what most people don't understand about Chinese censorship is that the foundation of their system is that everything is attributable to someone eventually. So they start by t

Hesai has driven the cost into the $200 to 400 range now. That said I don't know what they cost for the ones needed for driving. Either way we've gone from thousands or tens of thousands into the hundreds dollar range now.
