Comment Re:Woke AI education is now a thing :o (Score 5, Insightful) 31

"Woke" simply means "I'm conservative, and the thing I'm calling 'Woke' is something that I hate". It has no well-defined meaning beyond that. I've heard things as diverse as "the concept of the Metaverse" and "removing copyrighted content so you don't get sued" described as "woke".

A practical issue with a circle is that it is not a circle until it is finished,

That's not the reason at all, AFAIK. The reasoning is, okay, we want people to be able to move from one place to some distance place in the city at the maximum comfortable speed, which is limited by G-forces. You have some guaranteed G-forces from first accelerating and then decelerating. But if it's linear, that's your only G forces. If it's curved, however, you also have radial G-forces.

The Line's train going from one end to the other (170km) nonstop is supposed to do it in 20 minutes, aka with a mean speed of ~510 kph. Let's say a peak of 800 kph. Now if we shape that 170km into a circle, that's 54km diameter, 27km radius. From the centripetal force formula a=v^2/r, that's 222,22...^2 / 27000 ~= 1,83 m/s^2, or a constant ~0,2g to the side. This is on top of the G-forces from your acceleration and deceleration. You can probably deal with ~0,2g in a train if everyone is seated without much discomfort, though it's double what's acceptable for standing passengers. But you can eliminate that if the city is linear (at the cost of increasing the mean distance that the average person has to travel to go from one arbitrary point in the city to another)

That's not to defend this concept. Because the city doesn't need to be 170km long; you can just made it more 2d and have the distances be vastly shorter (at the cost of just needing some extra lateral travel within the city). Honestly, if I were building a "designer" city from the ground up, I'd use a PRT (Personal Rapid Transit) system rather than trying to make it super-elongated.

What got me is that I don't see why this isn't readily resolved by active damping, the same systems that many tall towers now use to resist earthquakes or resonant wind forces. Big heavy weight at the top (or in this case the bottom) hooked up to actuators that make it move in an inverse direction to the sway.

Again, this is not to defend this colossal waste of money. I just don't see why there aren't ready solutions for this specific problem.

Agreed - but that said, there are space elevator alternatives, like the Lofstrom Loop / Launch Loop, which at least theoretically can be built with modern materials (and have far better properties anyway - not latitude-constrained, provides dV, vastly higher throughput, far more efficient, stores energy / can add cheap energy at off-peak times, etc). One could always "waste" money on them trying something new :)

Even as someone who votes left more than any other way, I'd be entirely okay with killing the AMT. It is a huge pain to deal with.

The real problem, IMO, is that Congress needs to get off its a** and pass laws requiring brokerages and retirement plans to provide all of the tax data in a fully computed form so that you can fill in the boxes on your tax worksheet and be done, rather than having to look through every single line and figure out which ones were short-term, which were long-term, which had foreign tax, etc. Even with TurboTax, even with basically everything coming from Edward Jones, it *still* takes me two or three hours every year to fill in the information correctly for my taxes. I can't imagine trying to do that by hand on paper.

Comment Re:An opinion - not terrible (Score 2) 44

I love to hate on macs but this isn't terrible at all. The old and new icons are both quite clear and their purpose is most always understandable 'except for the two window icons replaced by an right-pointing arrow, I have no clear idea what either that could be doing), supported by shape and colours (though a more intense contrast could be desirable). These are icons I would enjoy using instead of the current "flat design" trend that exists elsewhere, for example the Breeze style in KDE which is what I would call terrible.

The real problem with requiring icons to be a specific shape is that it makes apps harder to recognize. Just look at how much confusion Google's icon rebranding has been, with every icon looking a lot like a multicolored square, and you'll understand what I mean. Now imagine every app icon on an entire operating system being a rounded square.

Comment Re:EV sales in *USA* plummet (Score 1) 308

most cars are more efficient at 55 to 60 MPH than at 40 MPH

I think the studies show 50 mph is the sweet spot for the same distance on highways. But you are right it varies by both vehicle and driving style. But the difference between 50 and the current 70-80 mph people drive on freeways is substantial for any vehicle.

Certainly true for highways, yes. There's also next to no good alternative to individual cars for highway driving, though. Amtrak is very, very limited, Greyhound is slow *and* very limited, airplanes are grossly fuel inefficient and are generally limited to relatively long distances, and that's about it.

The other part of the equation is how many miles someone drives. Lower speeds mean people drive fewer miles because the real cost of a trip is the time it takes. If you drive 8 hours at average 50 mph you only go 400 miles. You drive at average 60 miles per hour you go 480. If you use 5 gallons to go 100 miles then you use an extra gallon of gas.

Not sure why you think people would drive fewer miles. Most people in cars are trying to get to a specific place, not driving just to drive. Would people plan shorter trips? Maybe for some small percentage of leisure driving, but leisure driving is already a small percentage of driving, so that's a small reduction in fuel use for a small percentage of a small percentage of trips. That's hardly worth the negative impact on everything else.

It is basically impossible for Tesla to ever be a profitable company now. It is madness to be investing in it. But so many people have put so much money in it and they are so afraid of losing out that we all just have to pretend.

That's not how stock grants work. That trillion dollars doesn't come from Tesla. It comes from the stock market through share dilution. The company can absolutely still be profitable no matter how much equity it chooses to give out.

For example the city I'm in, if you make your house two stories (the maximum, by the way) the required setbacks triple in size so your house won't be any bigger.

Yeah, your definition of "mega-mansion" definitely is a starter house. My parents' home was two stories plus a basement. I can think of plenty of three-story houses that aren't even remotely mansions (e.g. row houses in San Francisco).

Penalizing people for using space efficiently by building up just leads to more suburban sprawl and lower housing density. It's the opposite of what any sane urban planner would recommend.

Comment Re:what happens (Score 0) 139

When someone builds a mega-mansion on your street, it makes the street less appealing as a whole and it makes your house look less attractive by comparison.

I would argue that having newer houses in your neighborhood is a sign that your neighbors probably aren't crackheads, so it should make your house look more attractive by comparison. The only time that might not be true is when the nicer house is also for sale at the same time yours is.

Also, those "mega-mansions" (which, based on having known a bunch of people who use phrases like that, are probably what we used to call a starter home back where I grew up) mean higher property taxes, which means better schools, which also increase the value of your property.
