2.5 times as much copper per vehicle as in ICE. 2.5 times according to the article that tries hard to be alarmist, so they probably don't underestimate. How much of the global copper supply went into cars? If it was a lot I'm sure that car manufacturers would have found ways to do with less (e.g. the dead simple step of moving to a higher voltage)
>Why didn't you give up more?

Because I didn't need to, and no one required me to? Because I didn't believe having to wear a mask, get a vaccine and not being able to eat out at a restaurant was an intolerable violation of my rights, given the alternative?

The alternative being the increased chance of getting COVID and the increased chance of spreading it to others. Not the permanent state of pharmaco-military-industrial complex imposed tyranny the anti-maskers kept insisting we would all inevitably descend into because "when governments take away your rights they never give them back voluntarily." Nope, here I am, not in a globalist labor camp, with all the rights and freedoms I had prior to the pandemic.

Obviously the balance between liberty and safety leads to anarchy on one extreme and authoritarianism on the other, but the question of whether governments can justifiably take temporary measures which interfere with individual liberties in order to mitigate a pandemic outbreak isn't an open one.
Cost and geopolitics.

A worldwide grid is absolutely possible from a technical perspective even with boring non-superconducting aluminium and/or copper, it's just that the combined cross section needs to be in the order of 3m^2, which is 17 years of current global output of both metals combined and has a current cost of a few trillion USD: https://news.ycombinator.com/item?id=32198057

(That said, my old linked estimates are over-simplified, that's a single minimal ring, and only works if the 64% resistive losses for current existing HVDC cables over that distance match the possibly lower demand because people do less at night).
I have not explored why, but facebook.com seems incredibly slow.
Why not just admit that the hot dry western side of the US just isn't suitable for the kind of dense human habitation that you have there, and move the people to a more sustainable part of your very large continent?
>> a lot of copper is consumed for applications that don’t need it. If prices go up, the industry can adapt.

Very likely true. This is usually the case with materials, and as the article mentions it is happening.

However... this doesn't mean that adaptation is without side effects. In a lot of cases, prices will just rise and the finished products will be more expensive and scarce.

It's pretty hard to predict downstream effects, but material availability is increasingly more of an issue.

Now i want to drive along a winding road in sunny mainland France eating a beautiful Jambon-Beurre.

They should make a lovely, pastel, electric version of this. I bet it would be a hit!
Ask HN: Is there a way to solve this using Maths?
Say, I have this following relation:

output_value = (V0, V1, ..., Vn)

The output_value depends on the input values V0...Vn such that some values when reduced may increase the output_value, and some values when increased may decrease the output_value. On the otherhand, increasing some values may increase the output_value, and decreasing some values may decrease the output_value.

Each Vk value depends on two values Vk_X and Vk_Y. The change in these various Vk_X and Vk_Y values determine the value of Vk and hence affect the final output_value.

A very crude hypothetical example, where there is only one input value V0, could be:

pay_per_employee(V0) = profit(V0_X) / number_of_employees(V0_Y)

productivity = pay_per_employee

(There could be many values Vk that might affect the final productivity value, but I have shown just one value)

Other real-world example could be calculating credit score.

Is it possible to mathematically represent this type of relationship of multiple input values on the final output value? If yes, then what field of mathematics does this fall under?

Also, is there a way in mathematics to avoid divide-by-zero errors in equations?
Left wing nutjob states "Fines and jail time won't stop me" - so what does he expect? The rest of us will just give up and let him break whatever laws he wants?
I don't have a backyard, but if it turned out to be the most effective and safe solution to, let's say, dig a deep borehole under my hypothetical lawn, drop the waste down there and seal it back up, why not?

From what I know of deep geological storage, I wouldn't mind living in a house on top of one of these sites. Since they're usually in the middle of nowhere, it would probably be even safer than living in a polluted city.
You are guilty of property theft. You forcibly took away something that belonged to another entity. The fundamental issue is property. No "economic damage" slips into the argument.
If that was the case, market competition would be illegal as you cause economic damage to your competitors. Advocating for veganism would be illegal because you cause economic damage to meat sellers. Inventing new technologies would be illegal because you cause economical damage to the old guard. Leaving anything other than 5 star reviews would be illegal because you cause economical damage. Calling for boycotting of unethical companies or states would be illegal (all hail anti Israel boycotting laws in the US). Etc etc.
This is a Google Search bug. If you search for something less popular, that exists close to a popular phrase, it will give you the popular results. Kind of like "horse riding a man" fails in both Dall-E and Google Image search:

Where do you see politics in this story? There's no discussion of Maynard's political views in the article, nor any indication that they may have influenced his behavior.
If workable (obviously crucial point!), I like the idea of using renewables, e.g. offshore wind farms, to produce hydrogen.

This would solve storage issues, vehicles could be refilled pretty much the way they are now, gas boilers could be swapped for hydrogen, no need for polluting batteries, no major upgrades of electric grid, etc.
>why nobody uses it really

If i where you i would stop use argumentation's like that.

OpenVMS has still the best Clustering tech...why is "nobody" using it? And btw p9 is very much used (WSL for example).

Linux is for sure not the best kernel, not for server not for desktop and not for mobile...it's good enough and everyone circles around it, it has some bacon for everyone (even if the bacon is sometimes disgusting).

https://en.wikipedia.org/wiki/9P_(protocol)

Same with unix in itself...it's good enough.

Some years ago you could argue that everyone uses mysql...why even bother with that postgresql-thing.
Shameless plug: I feel a bit sad that my own project rpgplayground.com never makes it into these kinds of discussions.

Although I have some hardcore fans, and I'm pretty happy with my community, there is something about my project that doesn't resonate with existing platforms like HN and others.

I always comfort myself that I have the same demographics as Roblox (more or less), and that was also 'hidden' for a long time ;).

Anyway, if you want to try out a super easy to use, but incomplete RPG making tool, give rpgplayground.com a try! <- another shameless plug ;).

Any feedback or perspective on my project is welcome of course!
My eye doctor graduated with EE degree, worked as EE for 6 years for a defense contractor, then went to medical school. He wanted to do things that save people and not kill them.

In reverse, I have a cousin who went to medical school, became a doctor, worked at a hospital for few years, didn’t like the work, couldn’t handle seeing sick people day in day out, decided to do MBA, then joined IT consulting firm, bounced between different consulting companies, later started his own IT consulting firm focusing on healthcare.

Residential consumption is not the issue, subsidized water for agriculture in California is. Agricultural users paid as little$70 an acre-foot for water, which is less than a thousandth the residential rate.

Under the state’s ridiculously baroque system of senior water rights, just because someone was first to nail a notice to a tree by a river in the 19th Century, everybody else in the area has to cut their water consumption to zero before their allocation can be reduced. No state politician has been brave enough to fix this because reform would be tied down in litigation for decades, as in Mark Twain’s possibly apocryphal quote that “whisky is for drinking and water’s for fighting over.”

This broken system does not incentivize efficient drip irrigation, in many places they simply flood the fields with water, and you have absurdities like the despicable Saudis buying up land with senior rights and growing alfalfa, a low-value and water-intensive crop they export to Arabia to feed cows, which is basically laundering water exports.

What is a makefile in 2022?

I use them as cross-platform task runners with commands like "make run-tests" "make run-dev-server". I use it for Go, Rust and even JavaScript (omitting npm scripts).

"make" is an odd keyword for such tasks but there really isn't another simple cross-platform task runner I can use.
You'll never know without trying it. Other people's experiences aren't always relevant to you, either.

The only way to understand is to just do it.
The article itself mentions scalability issues; but beyond this - there are often many complications in Makefile construction which result from idiosyncracies of libraries, utilities, platform settings, tool versions, etc. etc.

I used to write Makefiles - basically in the vein of this post's suggestions; but for several years have switched to using CMake. I have not had reason to look back. Why would I want to write Makefiles directly? What's the benefit?
> Not sure if you'll see this but I'll give it a shot

Thank you :)

The Wikipedia page on Ubiquiti also paints a bleak picture of the company; GPL violations, vulnerabilities, etc. I admit I brought 2 U6 Meshes on account of them passing the wife acceptance test, and so far they've been good (Some minor "Multicast Enhancement" issues aside). I haven't been interested in their router / gateway offerings since I think there's better out there with a better bang for buck. But its promising hearing about TP-Links efforts and I'll certainly give them another look if I need more Wi-Fi gear.
Oberon language and Oberon OS are two distinct entities and given the context of this post it's obvious that I was talking about Oberon the language. Whether you like Go or not, it's the closest modern production language to Oberon and derived very much from it, so my point stands.
Are you happy with the outcome? I think there are better ways to avoid it getting stolen :D

(1) Yes, the modern ML/AI lot seem to ambiguously use a purely mathematical meaning to "computer" -- which is useless. As useless as any pure mathematics. If we only had this a "computer" would be a theoretical curiosity, like a 200-dim sphere.

The real-world computers we care about run algorithms whose semantics is given by the properties of the devices real computers use. This double meaning to "computer" has caused a lot of superstition in the ML/AI space.

Real computers are engineering devices which shuffle electrical signals around to useful devices.

There is no reason to think that "pure algorithms" have any use at all, as with, eg., a 200-dim sphere. They're only useful if they can be given a semantics which exploits useful properties of devices. (cf. with physics, where a 200-dim sphere could be useful if it models some actual system).

(2) This isn't enough. Consider learning the rules of chess; or likewise, the inference rules of mathematics. f(x) = 2x^2, f'(x) = 4x, etc.

Search spaces constructed for a grad. desc. search are very infinite; and the solutions we need are infinitely precise. Discrete approaches to search(ing for solutions) are necessary.
Ha! Thanks, I needed a laugh this morning.

But seriously though, since when did Laissez-faire economics and legislation ever lead to sufficient safety not to kill people or burn down their homes willy-nilly?

HN is the only place I visit that has such wild ideas as "safety regs are too burdensome, let the free market sort it out".

Pumped storage has a carbon impact because of the massive amounts of concrete involved. The EU is looking at hydrogen storage instead, with the idea being that the natural gas distribution and storage network will gradually shift over to hydrogen which is produced from surplus solar and wind.

Ofcourse, you first need surplus solar and wind, and that's what the real problem is. There is still plenty of headroom to build more solar and wind for immediate use before we reach the point where some of the produced energy needs to be stored.
So what if a housewife/family refuse to purchase any product another housewife/family is pushing? Is there any rejection of said family? Is the whole family networking system based solely on sales? Is it considered not cooperating, from a religious stand point, not to purchase these products? Will church status be effected if purchases aren't made and a family punished?
You've lived and traveled in Califoria and the west but have you tried to grow anything here? There's a reason we've built vast megaprojects to pump water around the West: our deserts have been the terminus for the biological nutrient cycle for millions of years through multiple climate cycles resulting in an incredibly fertile ecosystem, despite its desolate appearance. Combined with the heat, it creates the perfect conditions for an industry that has dominated the nation's agricultural production in foods that humans want to eat. It's a lot easier to move water than to increase the carrying capacity of an ecosystem.

At this scale, regional sustainability is an illusion. Even the Amazon rainforest is not sustainable without _transcontinental_ winds that carry massive amounts of nutrients from African dry lake beds to South America [1]. Make no mistake, we're not just talking about the sustainibility of cities in the western US but food security and quality of life for the entire United States.

That might be truer in some cities than others. I'm currently visiting Yerevan where there are lots of scooters. Yerevan is hilly and hot, and your choices for public transit are cabs or busses, the latter being pretty inaccessible for tourists, especially if you can't read Armenian. Scooters seem like almost the ideal way to get around for distances of a few miles.
> In practice, just like everything in engineering, you don't run your grid at 50 Hz nor your railroad at 50/3 Hz. You run the grid at some frequency that varies slightly around 50Hz. There's always engineering tolerances.

> So even if you don't like rational numbers, it doesn't really matter whether you run the railroads at 50/3 +-0.01 Hz, or at 16.66 +-0.01 Hz.

In practice the nominal frequency was changed to 16.7 Hz anyway due to some weird edge case created when running motor-generators [1] for prolonged periods of time at exactly the nominal 3:1 frequency conversion ratio. (See https://de.wikipedia.org/wiki/Bahnstrom#16_2%E2%81%843_Hz_ge... and use an online translator at your own peril if necessary.)

[1] These days, newly built (or probably occasionally re-built) substations prefer to use solid-state frequency converters, which are immune to this particular problem, but there still are enough of the older motor-generator sets around, too. Wikipedia also claims that motor-generator sets are more tolerant against earth faults, which might or might not preclude against getting rid of all of them even long-term.
Dude your friend seems cool with his 3D printer but those don’t move. The problem is that people move and want convenience where ever they go.

I own a car and yet I still Uber and walk. Sometimes you walk somewhere and are too lazy to walk back. Maybe you walk to your friends house and they drive you to a restaurant and now you don’t want to walk all the way back. Tons of use cases where “transit comes to me” is better than “I go to transit” or “I babysit transit”.

Cars ruin cities and are expensive. Scooters are comparably cheap and low impact (visually, physically, acoustically, etc). The issue is that the road system is designed for cars (lanes) and sometimes walkers (sidewalks) and by a rare miracle bikes (bike lanes). Do you drive scooters in the sidewalk (illegal, annoying, likely to get them banned) or in the street (dangerous, bikers all have horror stories, nevermind scooters!) or ambiguity (bike lane?). If we had “alt mobility lanes” for bikes and scooters and one wheels and long boards and all that shit then it’d be so easy.
Yes, I can also write a big Makefile to hand compile my project; I can also compile it using shell script that explicitly executes the build steps.

…but I dont, not because it’s impossible to do but because the effort in maintaining those is high.

Come on, are you serious? Hand crafted makefiles? Have you actually tried to maintain one of those? That redis makefile has a explicitly coded set of object files. Can you imagine trying to maintain that for opencv?

I’m just too damn lazy to waste my time maintaining that kind of stuff; it’s a pointless, thankless task… but hey, I’ll give it to you; there are people out there who prefer to do it that way.

I posit, they spend more time maintaining their build system then they would prefer, but they keep make for ideological reasons, not practical ones.
"Isn't that incredibly obvious? " I just asserted that it is not. That was my entire point. I'm not sure how you missed it.

Your assertion that everyone who doesn't agree with you is a liar is problematic. I recommend really thinking about it and the ramifications. You are saying millions of people all agree with you or they are dishonest. Or possibly confused and they will agree with you when the confusion is cleared (unless they are dishonest). I can say I am not convinced and I'm not a liar or a person who is defensive and embarrassed by my not knowing this previously.

I was not aware of this provision that the software must be available for any use until this year (I've been using/involved with FOSS software for about 22 years - unfortunately a good number of years less than half my life) and it didn't occur to me as being necessary because to me saying something like, "this is open source except for military use" or "this is open source for non-profits" seems just as reasonable as "you can't modify this code and distribute binaries unless you distribute that new code". For people willing to agree to the terms, it is open. For the people unwilling to agree it is not.

I've never been really involved on the legal end of it all. In business contexts I used whatever was approved and the personal projects I've done, I've always used an MIT license because it was the easiest for me to understand.

I found out about this on github when I saw some issues opened on a project, because it was described as open source but the license didn't fit the OSI description. I found it to be interesting but also disappointing because it seems to be an issue of "comply or be attacked". There were links about why the vitriol was justified, but I read through it all and wasn't persuaded that the anger directed at the project owner was appropriate.

A license by its very nature restricts things. It's just a matter of which things and I think there is room in this space to be a good actor and have a different opinion. As the GPL says, "To protect your rights, we need to make restrictions..."

I don't see a long chain from "I don't want anyone to keep you from reading and modifying this code" to "I don't want someone to use this code to create an environment that takes away the human rights necessary to read and modify this code".

The fallback position I've seen is the one repeated here - "Everyone already knows and agrees with this except bad actors." and I just doubt that's true. Too many people make software and it's too large a group for me to take at face value any claims regarding a majority understanding. I'd want to see something objective that shows the work was done to know this rather than it just being an opinion or reflective of anecdotal evidence.
Does the average Googler have much input on product lifecylce decisions?
Across the history of man the greatest mass killings of people were instigated by atheists e.g Stalin who murdered millions simply because they were Christian. Most wars are tribal fights where the religion correlates to the tribe and it has little to no effect on causing the war. You even said yourself that it does the opposite, it placates it.
The Germans could not even properly manage one of their test locations (for weak and medium-level radioactive nuclear waste, not for waste from nuclear plants) longer than a few decades. One person who worked there said that after a few years they didn't know anymore what and how much exactly was stored there.
Your problem there is that you have agriculture at all, in a desert. Deserts aren't great places to grow food, and in turn the lack of food and water means that deserts aren't great places for people to live.

There's a bootstrap problem to be solved. If you want water, you need ground-covering plants, which need moist loamy soil, which needs water, and so on. For any of this to work you need to start by turning as much grassland as you can get into pasture (with irrigation, sadly, which needs water) and grazing it with livestock, and then kind of building that out over time.

Monoculture arable farming makes deserts. You need to stop doing that.
I wonder if it is faster to solve it by turning, or by disassembling and reassembling in the solved state.
