"Stride length is the distance covered when taking two steps, one with each foot. It's the distance between the point where one foot strikes the ground and the next time that same foot strikes the ground."

2.5 feet per stride? Do you shop for clothes in the toddler section? Even then, wouldn't it be 550 feet per day?

Comment Re:who's "AI tech stack"? (Score 1) 61

"America's Tech Stack" is basically NVidia's CUDA. AMD has a similar stack (ROCm/HID I think.) Huawei's AI chips would be something altogether different, as I would expect Apple AI. From what I've read, current software development for the various AI chips is very hardware specific. That is, there is no efficient translation from NVidia->AMD/etc. or vice versa. So the stated theory is, we want the whole world using one of the U.S. proprietary stacks (even if Open Source,) effectively locking the world in to our hardware architectures.

I'm not interested in arguing the finer points about how we would all be better off using completely open chip architecture and software interface layers, because of course we would. But that's not today's reality.

Comment Re:Just one of many, many, many problems with hydr (Score 1) 58

Like you, I'm all for improving Hydrogen technology. I still don't understand why we aren't cracking H2 out of the excess methane that is currently "flared" off of the remote NG pump sites. I'm not certain the exact process, but in places like West Texas it sure seems like we could park a windmill next to it to provide the power, eliminating the need for extending the power grid all the way out there, or even running a pipeline although you'd have to transport the H2 eventually.

The real problem I see with H2 is its energy density. It's nowhere near that of fossil fuels, so the physics says you'll need more H2 to equal the same energy of oil/gas/coal/whatever, regardless of how you convert it to electricity. I'm sure there are good applications for Hydrogen Fuel Cells and we should pursue them, but cars ain't one of them.

Using 2023 numbers, if you "taxed the billionaires" as you say, you would only fund Medicare and Medicaid for 4 years. That doesn't even touch what is spent privately on health care in the U.S.

I'm not saying that the rich shouldn't pay more. There should definitely be changes to how taxes apply to those who mostly make their money on Capital Gains among other things. Any I'm not saying that all social constructs are bad, with things like limited social safety nets, the fire department, etc., being good and part of civil society. But as Margaret Thatcher so wisely once said, “The problem with socialism is that you eventually run out of other people's money.” In this context, we run out in less than a decade. Then what?

This is basically right. VCs play the "throw stuff against the wall and see what sticks" game. The trick here is, most VC managers aren't using their own money. They are employed by the people with the money, who in turn invest in numerous Venture Funds at a time. The whole idea is that you invest in X number of companies hoping that X-(X-1) of those companies makes X^2 returns. It's gambling, and is generally the so called "First Round" of funding, which is also often supplemented with heavily levered loans. The founders of these small start-ups almost never make any serious money, and the vast majority go completely out of business because of the debt load.

I use my (second) 3D printer all the time for stuff around the house, for my bicycle, professional audio, etc. It's great to make custom parts exactly the form factor that I want them. But you're right, there is a fairly steep learning curve in both hardware...my first printer was "OK," but taught me the basics and what I wanted...and in CAD. And then of course there's learning the different materials and related tuning. It was a lot of fun hours invested, but I now have something I can just crank about anything I want out of, particularly when no vendor sells just exactly what I want.

Disclaimer - I'm not a concrete expert. But I do know that there are many varying grades and mixes of concretes depending on application. Sure, this may not be a fix for all concrete applications, but then no concrete formula is. That doesn't mean that lessons from this application can't be applied to others.

I matters to the labels and the likes of BMI/ASCAP/SESAC if they have no rights to the AI generated music, and therefore no way to make money off of it. Their extortion game ends this way. If AI music has to take over the market long enough for all of them to go out of business, I think society wins as a whole.

Comment Re:if u want 2 kill dolphins (Score 1) 74

Right, but it's not really NIMBY against solar in general. It's more about covering productive farm land with panels instead of producing food. It doesn't take a rocket-surgeon to see why people may not like that.

In non-agricultural areas, like desert, the opposition is mostly about modifying the habitat of highly-specialized plants and animals. While I don't dismiss this argument, I think the problem is these areas are also usually further from the grid than agricultural land, so they don't make a ton of sense either without huge investment.

No-one wants those jobs because they pay so low. The pay so low because the largely immigrant/illegal workforce is willing to accept that level of pay. If that workforce is no longer there, Supply/Demand will dictate that the wages will increase to attract workers. Yes, that may increase the costs and ultimately the prices of those goods, but there will be a larger customer-demand base, so it will largely even out. This is Econ 101 stuff folks.
