In table 3* the study summarizes 4 categories of generator.

Low speed Permanent Magnet PMSG
Low speed Excited Synchronous EESG
Mid to High speed Geared PM PMSG
High speed Geared Induction DFIG

All these types are currently competitive in large wind turbine installations, with high PM content designs getting selected in quite a minority of cases, despite modest efficiency and maintenance bonuses, even at the current top end of generator scale ~8MW.

To get beyond 10MW generators advantages of PM are desired but are also lumbered by relative heaviness besides the price of rare earths. Superconducting Magnets do seem like the way upward then, if reliable 'super-cooling' can be achieved.

Compensation once adequate doesn’t yield directly in performance for higher level tasks.

Teachers apply knowledge, experience and work in a way that magically makes you smarter and informed. Their effectiveness is a measure of their skill and the students. The argument against the unions is bunk — paying a premium for a math PhD to teach high school is probably pretty dumb... experience makes you effective at teaching trigonometry, not PhD expertise in math.

Go to any catholic school and you’ll see woefully unpaid teachers doing an amazing job — because the parents and therefore the students are very motivated.

The discussions about developers are similar. You need to overpay for people in a few metros... but you can pay a lot less for skilled people all over the place. The wacky salaries in industry have more to do with control and investors than the actual work.
I think there's a real reason here which the article doesn't mention: the more confused you are about what you're purchasing, the more likely you are to pay more and get less.

That could be true, but I also wonder how many people look at the weird bazaar that is the average website and then throw up their hands and buy Apple instead. Less hassle, etc.
This is the idea that’s been stuck in my head about G but I didn’t have the right words to express it.

Figure drawing.

It taught me how to see. The professor was absolutely amazing, and the stuff he taught us was as much about life as it was about drawing.

This led to later courses in painting and photography that expanded on this. I almost became a professional photographer, but I realized that the art was addictive for me in an unhealthy way. I would get lost in my art and forget to eat, sleep, etc. While exhilarating, that was not the life I wanted to lead.

Note that the quality of the professor matters much more than the specific medium for most art courses, imho.
Yes! This talk was fantastic!
Sure the issue is when employees don't feel like they can leave, because they can't afford a period of unemployment and don't have the time/energy to seek new employment whilst working 12 hour shifts and potentially supporting a family.
> Facebook has demonstrated they have vision and the ability to execute and adapt.

I'm a former attorney who worked in the investment industry and one of the shitty things I had to do when I first got out of law school was review footnotes on marketing material. In that industry there is one footnote that is basically the gospel: "Past performance not indicative of future results."

Has Facebook demonstrated their vision and ability to adapt? Absolutely. So did Kodak, Sears, and Apple. Though Apple managed a turn-around they certainly had a point where they very likely would have gone the way of Sears until they brought Jobs back.

Prior ability to innovate and execute means nothing. The important thing is continuing innovation. What the company is doing _right now_ is orders of magnitude more important than the longest track record of success. If anything, I think innovation becomes more difficult the bigger a company gets and the higher customer and investor expectations get.
Saying Lenovo’s website is terrible is the biggest understatement. Its probably one of the worst ever made.
You can just edit the buttons on the Touch Bar if you don't want Siri on it. Also, I don't see any change in behavior with the Touch Bar in Mojave. Touch drag works on both brightness and volume just like before.
At this point in my life I've started to believe that whenever you talk to someone who is "passionate about technology X and clean architectures" or "wants to work on challenging technical problems" is ultimately doomed to fail when setting out to create a (for-profit, bootstrapped) business. This is a strong opinion and there is certainly a spectrum for this mindset, but at the most extreme your mindset should be more along the lines of "all technology ultimately sucks, let's figure out the most straightforward way and the least amount of effort and headaches so we can create value for our customers so they, and we, can get off that damn computer screen and enjoy the fruits of our labor".

If you're saying "I'm passionate about delivering great products to users" or even "I'm passionate about making money" (I respect that) then technology becomes the tool you unfortunately have to wield to arrive at that goal.

Note that this attitude only applies to people who want to take ownership and deliver a fully functional product. There's tons of great people who are in it for the sheer enjoyment of working with technology, they all will have a great time working on challenging problems at one of the many tech companies. And there's a few people who can both enjoy technical challenges but also switch to dumb and boring crunch mode when it's demanded by the task at hand.
Agreed. After looking at the a few videos it seems to go a bit beyond the basics, I don't think that means it's "advanced."

This got me thinking: what would an "advanced" Deep Learning/RL course even look like? The field is so immature it's hard to identify topics that are advanced. Maybe an advanced course could be a chronological paper survey? Certainly not a class that spends a lecture on optimization of a deep network.

I think you may need to forget who the author is for a second and reread this.

He admits luck plays a huge role in success [0] (especially if you're using the success of others to measure your own success).

He's saying competing with yourself is the best way to measure success and achieve fulfillment. This probably stems from a lot of people using him as a barometer of success in tech. Comparing yourself to others is a great way to be miserable forever.

[0] "Besides, you only have limited influence on whether you’re going to succeed at whatever you put your mind to. It’s by no means within your exclusive sphere of control. There are so many things that have to come together at the same time. Only a couple of which you own."

The statement isn't that all public run healthcare systems are terrible. The statement is the United States governments, either federally or as individual states, are likely incapable of creating or running a non-terrible healthcare system.

We've already got at least a Medicaid system by state, federal Medicare, and federal VA. Are any of these non-terrible? Is there any realistic reform towards making them non-terrible? Is it realistically feasible to scale any of the non-terrible ones up to service the whole US population?

Certainly, it's possible for a government run healthcare system to not be terrible (or at least, mostly not terrible; any healthcare system has to make some hard choices at times, and people don't usually like it when they're the hard choice), and I'm sure you can find examples of that; but it doesn't seem possible with the governments the US has.
These fools are making a combined income of ~$175,000 per year and can’t manage to pay their modest mortgage or stay out of credit card debt. Capitalism isn’t their problem.
You bring up a good point. There are a few things going on here:

https://en.wikipedia.org/wiki/Aspect_ratio_(aeronautics)

https://en.wikipedia.org/wiki/Lift-to-drag_ratio#Theory

https://en.wikipedia.org/wiki/Helicopter_rotor#Overview

In general, the lift to drag ratio (L/D) of an airfoil is proportional to the square root of the aspect ratio (AR). For airplane wings, this hits a limit of about 60 simply due to the difficulty of reinforcing a long wing while keeping weight down.

A helicopter rotor spins, so has different requirements (like greater strength near the hub) so can have a higher aspect ratio. Unfortunately the inner third of the rotor turns too slowly to contribute much lift, and the tips shed large toroidal vortices that diminish efficiency. The tips also encounter turbulence near the speed of sound which diminishes efficiency. So rotors (even on wind turbines) can't really get higher than 60% efficiency:

https://en.wikipedia.org/wiki/Betz%27s_law#Betz's_law_and_co...

There has probably been more research in helicopter rotors over the years than increasing the L/D ratio of light aircraft, which explains how they reduced some of the discrepancy between the two.

When I was doing research for the Sikorsky human powered helicopter competition (unfortunately someone already won it haha), I did a lot of napkin calculations for this sort of thing:

https://en.wikipedia.org/wiki/Igor_I._Sikorsky_Human_Powered...

Success came down to having the fewest, longest, thinnest, lightest rotor blades possible:

http://www.pitt.edu/~jdnorton/Goodies/TE-antiTE/

There are many ways of increasing lift using winglets, vortex generators, EHD devices, etc (a few other keywords to look for are boundary layer and Reynolds number):

https://en.wikipedia.org/wiki/Wingtip_device

https://en.wikipedia.org/wiki/Vortex_generator

https://sbir.gsfc.nasa.gov/content/aerodynamic-efficiency-dr...

Personally I don't think we've even scratched the surface of what's possible in L/D ratios. With modern materials science and computer simulation at our disposal, I'd like to see someone break 100. Probably by using an array of airfoils and some EHD effects. I don't think anyone is seriously looking at it though other than maybe Bigelow Aerospace (JP Aerospace) and their defunct airships-to-orbit project:

I think this idea has merit and is one of the only ones that can compete on price with a space elevator. But it's not sexy enough, and people are still stuck on the idea of using helium instead of hydrogen, which sabotages it from ever succeeding (due to the limited supply of helium).

I would love to work on revolutionary ideas like this, but like most of you, I'm building SPA CRUD apps on the web to pay the mortgage. Sorry there's a lot of info here, but hey it's black friday on HN. What else are we gonna do.

I didn't mean to imply anything like that, but instead that we shouldn't fool ourselves when we use our electronic devices or put on our clothes. It's not like bad work conditions are a new thing. We have been profiting from them for a long time. It's always easier to look the other way and find a scapegoat.
I was never a hardcore Apple user. Only started seriously jumping ship at November 2017 when me and my wife bought iPad Pros and iPhone X for both of us. Had the MacBook 12" from before.

Then I bought a refurbished MBP 2015 15". Couldn't be happier with a laptop, honestly. Only thing I hate is when you load it heavily for a few minutes and the fans start wailing like a banshee. But truthfully, that's just a hate towards laptops in general. :D

The MBP 2015 is extremely durable, still lightweight enough, very powerful -- on compilation it seriously outperforms the 2nd gen i7 CPU on my gaming PC! -- and has a respectable battery life even when loaded. Never had to look for an outlet before I hit 6 hours of coding and compiling. And if I wasn't doing much compiling and mostly was just reading, coding from time and time, and watching videos, once it actually lasted for 10 hours.

So again, I ain't an Apple expert but ever since I got the MBP 2015 and read countless reviews and stories about the other models (like this thread) I still can't see what would ever entice me to buy another MacBook. Especially having in mind that the keyboard of the MBP 2015 is much better compared to anything on any subsequent MacBook so far.
It's easy to think, as long as there are an even number of lonely people in an area you can just pair them up and everybody can have companionship.

And yet, the world is full of buildings full of people, most of them lonely. Or all watching TV instead of talking to each other.

Walking into a room full of lonely people and trying to make them all feel less lonely is incredibly hard! There seems to be a shortage of people who are good at it. It therefore seems like a reasonable thing to try automating.
It's 15th century German as well, so it would be quite a challenge to read even if printed in a modern font. At least I could decipher that the animal on page 110v is supposed to be a giraffe (the drawing matches the description and the description matches a real giraffe, but a lot was lost in translation).

Emotional labor is not referring to the completion of material tasks / chores, nor is it referring to the amount of hours completed at a workplace. So I'm not sure what it is that you're trying to communicate by responding to a comment that was specifically about emotional labor with this comment - emotional labor has nothing to do with "talking bad" about relative degrees of contribution in a relationship.

edit: now I see - it's related to the comic in the GP comment. That comment implies that the comic is explaining emotional labor, but it isn't (the comic pretty much states this in the final panel). So that GP comment confused the thread. I'll respond directly to that comment.
So you agree with GP that the storage problem is currently a problem and needs to be solved.

I know I'm nitpicking here, but I find it annoying when people say things like: "If you’ve yet to read these x books, do yourself a favor and buy them today".

Did myself a "favor" a few times in the past and every single time I only read the first couple of pages and ended up giving them away. Or worse, I get FOMO so I keep those books around and it becomes clutter around my small apartment.

Its hard to focus and read the rest of what the author has to say if he makes blanket statements like that.

Their strategies certainly are terrible for the educated consumer. But might there be a method to their madness? For instance, if you believe customers:

1. primary buy based on price

2. buy from retail outlets based on that outlet's marketing

Then it might be reasonable to have a swamp of very similar models specifically so that customers can't easily comparison shop between different retail outlets. A deliberate 'dark pattern' if you will.
The more infuriating thing is that these cost controls exist because CPAP is a hot prescription that’s being overused.

You probably still have ADHD, or at least enough trouble with the things ADHD folks have trouble with to get an official diagnosis and prescription.

Like, the first psych wasn't wrong about anxiety being a thing. It often is very often co-morbid with ADHD. This is because ADHD interferes with keeping up with work and life commitments and deadlines, makes you tend to work closer to deadlines (and more vigorously), and causes other life issues. If your work performance is unsatisfactory, of course you are anxious.

HTTP/2 works well, so adoption speed isn't that important.

On the other hand, HTTP/3 is way, way faster. So there are strong incentives for big players to adopt it as fast as possible :)
I'd say the MVA (or MVP, or Apple MVC) pattern is overused.

There is usually neither a point to separating the view and the model like that, nor is it usually possible. In practice, you get lots and lots (and lots and lots) of glue code that is (a) boring, (b) repetitive, (c) error-prone and (d) non-reusable.

The code is non-reusable because it is specific to both the view and the model. And it doesn't usually help in keeping the view model-agnostic, because after all the view is there for displaying the data that's in the model. Additional layers can't change that fact.

I didn't suppose you were arguing for libertarianism; why would you suppose I was arguing for a "nanny state ruled by a philosopher king"? I would say that the story of Tom and Kate (taken together with millions of similar, if less extreme stories, as well as, e.g., many other different types of exploitation described in Shiller's book) _does_ stand as an argument against unrestrained, laissez faire capitalism.

The fact is that unrestrained capitalism breeds opportunities for businesses that tend to exploit people's natural foibles. There are ways to prevent this (e.g., intelligent regulation) within the capitalist system. See, e.g., Shiller's book.
I also found that to be an awesome little tidbit. Just human nature I guess... "I wish it wasn't like this! But it's the most convenient so click click click!"
I think its caused by disenfranchisemnt. When you feel like you have no control or are involved in decision making, it's easy for that to break down trust. That's what I see in myself, and those around me.
Can you point to many examples of non-capitalist societies where conditions are better for most people than in the United States?

From my perspective, capitalism has lifted more people out of poverty than any other economic system in history.

By what metric has it “failed” ? Because the bottom few percent live in shitty conditions? Before capitalism, the bottom 90% of people were illiterate subsistence farmers.

Bear in mind people already pay a price but refusing to get vaccinated in time.

There's many better ways to explain the role of luck in success, but I felt the way he mentions that was an add-on to his whole message of "don't bother." Competing with yourself improves you, not your positioning in the real world. When you improve yourself and the real world is more bountiful, that's a minor side effect purely based on your context and environment.

In the whole article, he doesn't bring up examples of others to make his point. His only source in this is himself from his point of view.
