None of the things you mention would have a significant effect on range, and all could be replaced with a nominal increase in runway length. If an aircraft cannot produce sufficient power to take off, it cannot produce sufficient power to climb.... And to be efficient, it must climb as high as possible, ideally to 30k feet or more. You are talking about the first 30 seconds... But it needs to keep it up for 30 minutes.

Take off assists are for ultradshort runways.
> How do we put a value on the fact that, for the cost of no more than a day's labor, most in the US can have a handheld device with access to nearly the sum total of the world's knowledge and entertainment?

I know that this is a tangent to your point and I'm not trying to be pedantic, but it always crosses my mind when people mention "access to all the knowledge and entertainment" — how much that would actually cost someone, even with the internet?

For knowledge — You have access to Wikipedia and it's a great resource for what it is, and more and more, universities are making some of their material available for free. But there's still an awful lot of academic knowledge that's locked up in research journal subscriptions and a huge amount of knowledge & expertise in e.g. industry text books from publishers like O'Reilly.

For entertainment, leaving aside piracy (as otherwise a discussion on costs seems odd), how much would it cost you to be able to access all TV, films, music, books? You'd probably need recurring subscriptions to multiple platforms to even cover main-stream (Prime, AppleTV, Disney+ etc.) Then there's titles that aren't on any subscription service, etc.

I wonder how many days labour it would cost to actually get access to all of these?
Well maybe you didn’t study have to study history at school. But I did and we learnt that the 1918 flu killed more people than WW1.

This discussion is about how producing meat requires tons and tons of land in the form of soy bean fields that feed the animals, which indirectly and directly contributes to deforestation. Now you come along and say, just eat meat produced using this other method which takes a lot MORE land for the same amount of meat production?
The amount of meat we produce and the stupidly low prices we sell it for are required by nobody. It's a want and not a need.

People want 1$ burgers. They don't need them. They can eat thousands of alternative meals to nourish themselves. Meat should be a luxury only, everything else is unsustainable and sooner or later the problem will make itself known anyways. We can still choose how inconvenient it's going to be, however.

I eat quite a lot of meat myself, choosing to pay more for better quality product with animal well-being in mind. I am dumbfounded at the availability of cheap meat.

It's 1.000x worse than international air traffic in terms of climate and ecology but somehow it's "normal" that everyone can get pounds and kilograms of meat for less than 10$. It's wrong and unsustainable and the only question there is if we control the inevitable crash or not.

You've almost answered your own question there. It's not more difficult to shut down due to a change in government behavior, it's difficult to shut down because it's highly decentralized, unlike earlier digital currencies

Or just stop, or reduce as much as possible, the amount of crap we eat? There is no reason why meat has to be that low cost. Or that we cannot cook ourselves with fresh ingredients, ideally grown and sourced locally.

Nutrition, being a basic of human survival, has been sovled for millenias. We just lost it with pushing industrialized food production, of any kid, way to far over the point needed to get rid of starvation.

There might be a 'best of both worlds' idea in there: If mold mmaps the input files instead of reading them, the linker would not trash all cached files, and be faster itself as it reuses already cached files.

Now the author seems a smart fellow, so maybe he did just that already, I didn't check the source.

I love Anders work, but TypeScript seems to have gone too far in type system experiment.

Configuring the compiler is now as complicated as selecting the right set of GHC compiler pragmas to successfully compile the code, and they are anyway type annotations that have zero impact in code performance, just a friendly than using JsDoc.

I look forward to when browsers just adopt WebIDL and be done with it.

you're absolutely right - preparing a high quality beef meal takes a lot more than just processing soy, but what I was aiming at was that we will replace one mass consumption with the other, just like we always do and that may mask the problem but I believe it won't solve it. I could be wrong though.
Ive always wondered about this "obsession" with finding life specifically.

For some reason I find it unlikely we will find life, and I'm probably wrong. But I also get the feeling from the missions that unless there have been life, there is no reason to go to Mars. I mean there are so many reasons to go there even if we never find signs of life.
Makes you wonder why this was removed doesn't it?

We've had forced "sexism at work" training. Actually wasn't too bad and was done in a tasteful way, and I think has been positive for our organisation.

From what I've heard about Coca-Cola's training, it talks about how to be "less white" - whatever that means. If that's the case then it's pretty disturbing, and is going to cause a lot of division. Good luck with the fallout Coca-Cola!

> What about the cone cell response curves which roughly correspond to r, g, and b?

The diagram is misleading because the spectral sensitivity curves are drawn using red, green, and blue colors on the chart. Read the wavelengths on the bottom--they do not roughly correspond to red, green, and blue. This is why they are named L, M, and S instead.

The peak sensitivities are closer to green, a different green, and violet.

> That is hardly a coincidence. Our perceived color space is vaguely triangular because we have vaguely three types of cone cells to detect color.

It's a poor approximation of a triangle. It's more paraboloid.

It would be a triangle if there were no overlap between the spectral sensitivity of different receptors. Since there is overlap between the green, other green, and purple receptors, the shape is not a triangle.

> Environmental and emission norms don't apply to SUVs due to lawyer magic

This is false.

SUVs need to meet emissions rules. Mileage rules are applied to automakers for the average of what they sell, allowing them to sell high and low mileage models as long as they meet the average. For federal EPA standards, SUVs and sedans both need to meet the same tier 2 requirements, and of course California applies stricter rules to both.

Perhaps you were thinking of the old tier 1 requirements, which had different rules for SUVs? That's two decades out of date. Since 2007, when the transition period ended, the much stricter tier 2 EPA requirements apply equally and make no distinction between SUVs and sedans provided the car weighs less than 8500 pounds. The largest SUV on the market, the Mercedes G Class, weighs 6800 pounds. The average SUV weighs about 5000 pounds, so no, they aren't dropping 5000 pound engines in them.

No they're not, at least they're not pasture. They're either already farmed fields or they're wild meadows. Putting meadows to intense use would destroy whole ecosystems that may look like "just grass" from afar, and farmed fields are obviously already in use.
I guess I feel returning error invalid integer for a valid json double is a bit wierd - but I guess it's not technicallyaany worse than "could not parse string as integer. It's more that it is expected that strings hold" other" data, like timestamps, while one might expect a double to hold only (but also any) doubles.

Not necessarily - I don't know about where you're from, but here our cows and sheep eat grass and live in fields that wouldn't be suitable for crops
Do you really want generated code to manipulate JSON? I'm not sure there is a demand for that.
The only viable place for something like Ami is car sharing in my opinion. The thing is, car manufacturers have been doing this since long before Tesla. They make something that screams 'look, I'm a weird thing that resembles a car, because I'm electric'. And the general population just wouldn't buy them. And then Tesla came along and showed that you can actually make a car that is electric and that people would want to own. In my opinion the market really has spoken. And what it says is loud and clear: "We want electric cars that look like cars and can be used accordingly."

I mean, if there was a huge market for small, slow, weird looking things on four wheels, there's no reason why ICE power-train driven devices couldn't have filled that niche a long time ago.
If you consider humans a disease, would you be ok with someone killing you? Because that's what you do to a disease, you get rid of it.
The issue is not judt the extra procesding cost.

I haven't ran the numbers, but parent hinted at a cow needing to eat, say, 10 Kg of soy per Kg of meat produced, while you could have just eaten the soy directly.

Meat production uses a lot of land to produce food for your food, that's why it's so inneficient. Instead you could just use a tiny fraction of that land, and grow enough food for everyone.
Your mind still didn't change, organic meat is about the same problem, you are killing animals to praise your palate.

What you are saying is: I no longer do normal and plain slavery, I now do organic slavery. Instead of importing people from Africa, I get my slaves from small cities nearby, which are well fed. It's all bullshit and marketing. You aren't anywhere more evolved for eating organic meat. It's hilarious to read your comment, it's basically everything what is wrong in the world. People finding more expensive ways of doing the same trash behaviour "with conscience". I can't believe somebody can fall for this.

Just stop eating meat and start to think of the animals, if you care.

Just like slavery, it took white people centuries to stop being lazy and assholes to stop with it. The same it will be with meat, when people start looking at eating meat as a very nasty thing that our evolved society no longer needs and also becomes unsustainable(we are already very close), people are going to start quitting eating meat.
A tiny car is in fact in-between a scooter and a regular car.

How interesting. Doesn't the fungus get its name from the oxidized metal though and not the other way around? Mold the form and mold the fungus seem etymologically unrelated, however.
I agree with your point, but: Eating it directly would be a lot mor efficient use of that soy and would decrease the demand for soy anyway.

Well, my hybrid electric car gets, on a summer day, about 70 km per 10 kWh charge. So if the locomotive can produce about 24000 kWh in a day, it could power 2400 35 km round-trip commutes.

Now a freight train will run at, I don't know, 120 km/h? So, theoretically, it could run 2 880 km in a day. As we can see, that's a lot less than the combined 168 000 km 2400 hybrid cars could drive.

So if we're comparing a train pulled by a locomotive like this to single-occupant hybrid electric cars, the train would have to transport 60 people to be about equivalent in efficiency. That seems very doable, you could fit that in a single train car. Also the 1000 kW power output is the peak output, I can't imagine a locomotive would be anywhere near it's max power very often.

Did I goof in my calculations? I may well have! But based on these numbers, trains seem pretty efficient.
A simpleton tree-hugger mindset will automagically solve our biggest global challenges for 8 billion people in the 21st century. After all, it "feels" like it will work for millions, so it'll end up working for billions too. And it makes you feel all comfy and angelic inside.

It's also much better for the environment than Tesla and other 2 tons electric cars, because it's using less materials and energy to make and less energy to run.
