Is this more of a centrifuge or a vertical flywheel? Centrifugal force is exerted away from the axis, but at the apex point where the centrifugal force on the object is strongest vertically, it’s lateral velocity (along the ground) is the highest and if you release it then, won’t it travel at an angle to the ground? Unless it’s releasing somewhere in between lateral-to-the-ground and at the apex.

The force is proportional to (v^2)r, so if r = 50ft (half of 100) and the linear speed is 2000mph (several times the speed of sound), my risky math in public works out to about 9.3 revolutions per second, and a linear speed of around 946m/s, so each kg of mass ends up exerting 5700kg on centrifuge (and itself). I think manned expeditions need a much larger radius, I’m curious how the physics here affect what gets launched.

Heck of a pumpkin launcher, but you’d need to fill them with concrete to survive the launch.

Or, perhaps the Chinese government revalues gold at $10k.
That’s actually quite doable in a garage, assuming you are satisfied with, say, two inch wafers. (Currently, they are approaching 18 inches!)

It’s much easier to produce silicon ingots than to do wafer fab, because of the currently tiny line widths.

But, it would make more sense to simply buy wafers (or epitaxial wafers).

Are you sure? The US military doesn’t look to be at its peak. Despite its massive budget China’s military rise and the return of Russian military power might be changing the US’s role as the worlds only military super power.

At least in my personal observation, it seems like star ratings elsewhere on the internet (I'm thinking particularly of Airbnb and Google Maps reviews) are probably pretty close to bimodal: by and large, people essentially use five stars as a "like" button and one star as a "dislike." Assuming this is the case, a rating of 4.8 stars is essentially a way of saying "95% liked this": why not just strip out the extra abstraction and complexity and instead use a simpler like/dislike model, just like that YT blog post argues?

Of course, there are other situations where ratings between 1 and 5 stars _are_ informative: think critic reviews of movies, video, etc. But I think most crowdsourced reviews have kind of converged organically to a like/dislike model.

82Hz is an E2, the 19th white key from the lowest on a piano. [1]

So it's fairly low but completely audible.

For megawatts, imagine a million bookshelf speakers playing the lowest note they can play, or 10,000 subwoofers playing the highest note they can play. Most people listen to music at less than a Watt power.

> Gross margin ... doesn't include workforce cost.

I don't think that's right. From https://www.investopedia.com/terms/g/grossmargin.asp

"The Formula for Gross Margin Is

Gross Margin=Net Sales−COGS
where:

Net Sales=Equivalent to revenue, or the total amount
of money generated from sales for the period...

COGS=Cost of goods sold. The direct costs
associated with producing goods. Includes both direct
labor costs, and any costs of materials used in producing
or manufacturing a company’s products."

It wouldn't surprise me if a lot of Tesla employees are compensated in large part via equity, therefore lowering their apparent labor costs. Also, they probably have lower health insurance costs for their relatively young workforce (they are more like a young tech company in this way).

Of course, battery prices will continue to decline, so in the
long run, yes, EVs will be cheaper to buy, but I'm not convinced we are there quite yet. They are already far cheaper to operate, though.

This book is recommended (and heavily upvoted) on every such thread about good software books but I would very much doubt more than 5% have read more than a few chapters, probably less than 1% have read one book in the series and probably less than 0.1% have read the entire series.

This is one of those series that everyone thinks they should read but few actually do.
They have warehouses all over the country and all over the world. If any of them shut down, they could temporarily send product from the others.

Why would it take years to find more unskilled labor? They could literally park a bus in front of the unemployment office in the morning, load people onto it and be running again by the end of the day.
I'm not sure how much you need to raise the island. Just matching sea level rise isn't enough, because Tuvalu would really be better off being a couple meters higher to reduce storm damages before climate change started, and climate change both raises the seas and makes intense storms more common.

But more importantly than the amount you need to raise the islands: 26 sq km * 1 meter probably doesn't raise the islands anywhere close to 1 meter, because of:

* Early losses from erosion and compaction

* The angle of repose around the islands (you can't just build the island straight up 1 meter).

Generally speaking the vast majority of money is created by the private sector and not the government. For the Fed to be able to "fix" this by printing more money would already represent a large systematic change. This isn't impossible but fending off a deflationary shock is far more complex than people tend to assume, I think in part because of underlying assumptions that the majority of monetary creation is done by the government when in fact that may not be the case.

> Voting rights.

Citation needed. Or rather, it's not needed. The Federal Reserve Board has 7 members, all nominated by the President and confirmed by the Senate, with a term of 14 years [1]. All the decisions of the Federal Reserve Board are taken by a vote of these members only. The record of the votes is public, and available at [2].

> Influence.

This is quite an unfalsifiable statement, isn't it? I claim that the Knights Templars have lots of influence with the Fed, can you refute that? In any case, influence has nothing to do with legal ownership, which was the thing we were arguing about. My first quotation was straight from the Kansas City Fed webpage, and states clearly that the Fed is not owned by anybody. The legal act behind the Fed is the Federal Reserve Act, which you can peruse at your leisure [3]. It will just confirm that. Or is that not reliable? Is the Constitution reliable, or maybe it's on par with the publications of the CCP?

I don't know if there's a word for it, but pretty much every nation has at least one other nation that it traditionally looks down upon, usually one that to outsiders seems quite similar and which often have in fact strong ties between them. France and England are a classic example, though maybe a little odd in that it's mutual. (I suppose Argentina and Chile are similar in that regard--each thinks the other is categorically beneath them?) Sometimes there's a clear regional hierarchy, like U.S. -> Mexico -> Guatemala even though it's not necessarily obvious to all involved--U.S. has traditionally looked down on Mexico but doesn't have any sense of a hierarchy beyond that, whereas Mexicans might not care less what people in the U.S. think but certainly feel they're better than Guatemalans. Sometimes it's a non-transitive circle. It can be very complex, and it doesn't have to make any sense, though often it's a simple reflection of comparative wealth or prestige. But it's a universally understood phenomenon. There's the famous quote by Jean-Jacques Dessalines, leader of the Haitian Revolution, who circa 1804 called the Polish "the White Negroes of Europe", exempting them from the murderous extirpation of all white-skinned people in the newly independent state. Fast forward to the 21st century and British prejudice against the Polish (and specifically Polish immigrant laborers) is a major impetus for Brexit.

Anyhow, I've learned to be careful about equivocating nations or cultures. Saying something like, "country X seemed just as nice as Y" might rub someone from X or Y the wrong way.

It's all thinly disguised racism, of course. But it does pose an interesting woke paradox: what if all a nation has left is its prejudice against another nation?

This is a very good question. No, we don't have a good clear dose-response relationship.

> harmful in total (our results are presently worse than if there was no homework at those ages)

Most studies compare schools / classes assigning no homework to various "normal" levels of homework, so they imply that our results are presently worse than if there was no homework.

I do assign homework to middle school students. But I don't do it often, and it's typically of the form "think about an idea on the topic of _____ we can discuss" or "do the first couple items of this lab worksheet so that we can use our time in the classroom more efficiently tomorrow." I enforce its completion with social pressure, not the gradebook. "Dude, you were supposed to do the first couple questions on the lab worksheet!"

I have a feeling that there is better homework we could assign that would be useful. But we don't have a lot of evidence of what that would be. Proponents of flipped classrooms think that is the path forward, but the research quality is very dubious in primary education.
If they implement should we all start intentionally spamming 'hot hash hits' to overwhelm the system? I guess someone would either need the CP hash already or break the law and morals to get one.

I really can't agree, the GNOME stuff I've used as a developer has been great for me. Keep in mind that no software project will ever be able to accept all possible feature requests or pull requests, for example I wouldn't expect System76 to accept everything that comes their way either. They have a specific design they're trying to meet too and that requires focusing on some things and disregarding others. I don't think they are trying to aim for something that is so good that it obsoletes everything else, that's unrealistic, you would have to invest a really large amount of money to even have a chance of doing that.

Tesla offers two things called FSD: first, there's the "FSD Beta" which can navigate on city streets (with careful supervision).

Second is FSD, which is the list of features here: https://www.tesla.com/support/autopilot#usingautopilot

Effectively, that second FSD gives you a grab bag of features like "lane change" and "summon", but doesn't give you what people think of with FSD (navigate on city streets).

You can still pay $10k to get FSD, but you only get the second thing by default. The first thing, what people think of as FSD, FSD beta, is limited to a small pool of beta testers.

I would not call that widely available. The FSD that is comparable to super cruise is still in a beta, and it's just awful naming of things which lets that page you link say that anyone can buy FSD.
Isn't that similar because the dislike value isn't related to the specific video but a person's opinion of the brand.

For example if you wanted to watch a video on how to setup WSL 2 on Windows 10 and you see one by Microsoft has 100000 dislikes however it's amazing video that doesn't help you.

Yeah, I'm actually behind this one. There's enough negativity on the internet, if youtube lose 0.25% of their premium subscribers they'll still be just fine. I doubt if much more than that will drop their subscriptions as the main value is lots less ads and premium-only content.
Search is hard. Let's go marketing.
This is an excellent point. A dislike value is a single number but represents a large variety of reasons, only some might relevant to if you would think the video is good, and you don't know the breakdown.

YouTube used to have 5 star ratings, they got rid of that in 2010 [1]. If stars and dislikes are so bad, why do they have them in the Play Store. I wonder if Trip Advisor and Yelp are next with only likes.

I did not imply that all majority-black cities run ineffective municipal services.

I did imply that it might be reasonable to expect a community of people that are tired from working all day and may not have grown up with the best education and influence to have given them the necessary experiences to be able to evaluate a city’s financial situation and vote accordingly.

They probably are not spending the couple hours of free time checking government budgets and reading minutes from city council meetings, much less attending them in pre internet days.

I even keep up with many of the local political happenings, but quite frankly, I rely on the good will and good luck of the decision makers in my community doing the right thing.

I honestly don't see a problem. If someone truly dislikes a video, they put in effort instead of encouraging a mob mentality by a high number of dislikes

Maybe Youtube can somehow incorporate the dislikes into "Likely to enjoy" score similar to how its set up on Google maps. It's pretty accurate from my experience.
