I don't imagine tutors are going to teach for free, but I do think the cost of education has generally spiraled out of control beyond what anyone could consider sustainable or reasonable.

In my dad's generation, you picked one profession, stuck with it for life, and had one or - if you were adventurous - two, employers. Retooling (and therefore continuing education) just wasn't required. You learned what you needed to learn in high school and perhaps college, and then you were done with that part of your life and moved on.

In this economy, people find themselves having a few different careers over their lifetime, and to facilitate that they need to revisit the academy a few times. But when you bundle together the cost of providing the education, the cost of supporting a large research organization (if at a research university) and the cost of a large physical plant, it gets super-expensive.

And then there are additional market frictions - I adore MIT as an institution, but even if qualified and admitted to their supply chain management program, there are a certain number of candidates who are going to say they can't afford the opportunity costs to NOT work for a year plus the out-of-pocket costs to attend. So, the benefit of such a candidate's intelligence and what they would contribute to the class, is lost in these frictions.

On the supply side, the high cost of resources dictates a high tuition price and an ever-present supply constraint: seats are limited. So, institutions limit the number of applicants who can get in and admissions committees do their best to select those from the applicant pool who will make THE most of the resources provided. But they're not perfect - they admit some people they wish they hadn't, and they reject others they live to regret not admitting. (Warren Buffett was famously rejected from Harvard - needless to say, the university now wishes they'd welcomed him with open arms...)

MOOCs remove this constraint - and scale infinitely - hence the cost can be very low indeed. But they remove the human component and no one knows yet whether LEARNING scales in this fashion.

uMOOC is trying to correct this flaw - to, quite literally, put the 'u' back in the MOOC.

So, HaoZeke, yes, money is made by tutors and the site, but it creates an environment where students who otherwise might get frustrated and quit, instead succeed and can move forward. That has to be worth something to society, no?

I'm trying to understand what "Log sine sweeps rather than linear sine sweeps were employed to allow verification that non-linear distortion components were virtually absent" actually means.

I understand that a log sine sweep means that the set of frequencies that are tested is itself logarithmic; e.g. you'd check 20Hz, 200Hz, 2KHz, 20KHz instead of 5Hz, 4005Hz, 8005Hz, etc. That makes sense to me. But I don't understand why log sine sweeps would allow you to check for non-linear distortion?

It often turns what could be a very fruitfull career- with contributions to a breakthrough- into a one-trick-pony.

My grandfather, a professor for chemistry, did as a student research on ion exchange resin - which later became valuable applied to water softeners. He did a lot of interesting research later when it came to analytical sciences (radio-chemistry) but that early success sort of over-shadowed everything.

Its a haunting experience, unless you dono longer externalize your value as a researcher.
It's more or less true that democratic societies tend to have developed in a direction we'd consider 'right', and I'd even agree that this direction is "right" in a sort of universal sense. But it's not actually the majority opinion that makes it "right".

In fact, the most impressive advancements have been in protecting people from the "tyranny of the majority". Things like due process even for terrorists, or presidents, or pedophiles would probably not get a majority.

Think about it: the system based on majority-rule happens to be the best if you're generally hated by everyone. If people like you, Russia doesn't actually feel that different :)

Language does not have to be consistent and mathematics are a game we play. Bitcoin is a single global public ledger created in a distributed system. To call it decentralized is strange since all transactions must go into the central ledger to be valid. In other words, decentralized systems function perfectly fine with inconsistency. Bitcoin does not pass that test.
Alright, I waded through the salient sections. It doesn't appear to be making it illegal, at least not outright prohibiting it. It also includes some verbiage for some research to be done - basically a feasibility study.

It looks like they're going to treat cryptocurrencies like cash. Somehow, it looks like they think they are going to be able to detect it at the border. I have no idea how they think they are going to do that. If you want to get around it, just don't leave evidence of it on your devices when you cross the border. Dropbox exists.

Other than that, they've already made it so that it is illegal to do certain transactions, over $10,000, without notifying the government. My understanding is that exchanges already follow this rule, but I bet there are some .onion sites that beg to differ, just a hunch.

But, it doesn't look like they are making them illegal. It almost looks like they are recognizing it as legitimate. If you read the proposal, treat it like a find/replace. It is modifying existing laws.
> limestone mining destroys the landscape just like any quarry does

In South East Asia, limestone quarrying and mining has destroyed the habitat of many species. There are dozens of species that are extinct, or are going extinct due to limestone mining. They clear entire limestone mountain ranges and turn them into cement.
>" It also makes things less flexible: as I understand, authorities must be notified of exact travel plans before you depart."

This isn't true. You are free to travel wherever and whenever you want in China provided you have a visa. Tibet might require a special approval but nowhere else. The visa is also good for 10 years. Also if you are a Westerner, hotels and taxis are a really good value in China. Lastly there are much better flight options into Beijing than there are into Taipei and so would more than offset the cost of the visa.
I thought quantum entanglement is the idea that two quantum particles separated by distance will behave the same at the same time regardless od distance.

Why is sending photons over distances a verification of quantum entanglement?

Can someone elaborate on what this is?
> We're never going to run out of lime. Ever. It is literally everywhere.

Not true. Limestone suitable for mining is a limited resource. That's why cement companies like Lafarge pay millions for mining rights in South East Asia. They clear out entire mountain ranges to turn into cement.
Can confirm from selling some wood from inheritance lands to pay the inheritance tax. Basically the good trees get sold for lumber and the ones not good enough become cellulose/paper (with the big machines you always do a full clearing as its more economical this way so you don't get to leave the small ones to grow etc.). This is from Finland.

And as others have pointed out most of the raw material going into the local paper mill was saw dust from the local sawmills.
As a child I dreamt of having two futuristic walkie-talkies sharing several pairs of entangled particles making perfect instant communication across the galaxy possible. Later my physics teacher crushed my dreams by telling me it's far from as easy as that and probably impossible due to Heisenberg's ... (no clue what it's called in English).
It's pretty awesome to hear that something similar is actively being worked on and seems possible, although being a huge challenge.
Let me share a "concept" in my union.

You dont have to be in a union to be able to gather together for the common Good.

So lets say your "manager" tosses out some ridiculous rule and each person individually thinks it stinks.

With the right leader, if you simply say "its us against you." and let them know you dont have a concern about consequences, it will get you very, very far.

Be daring. Be challenging. Dont get walked on. Stand up for what is right.

Having a union frame of mind can actually help.

With Peter Thiel and Carl Icahn as both close Trump advisors and Lyft investors[1], I wonder if the damage done on one side will equal the benefit of these lofty climate goals on the other?

That being said, we need every company to do their part, so kudos Lyft!

A staple of sci-fi has been a pair of boxes with quantum entangled particles inside allowing FTL communications once the boxes travel (sub-FTL) to their destination.

By my understanding that's impossible, although I always wondered if you could coordinate FTL, by detecting when a particle was no longer entangled.

Can someone with the background comment?
I believe it is changing things but far away from western society.

I believe that instead of using force on nations in the middle east for example you only need to use information. The people will seek out information and this will cause them to question the status quo simply by comparing their lifestyle and culture to someone elses.

Deep down most people all want the same things.

Bombing them into oblivion only hurts this because they distrust any information coming from the aggressors.

Looking at western, developed societies - what I like to refer to as e-nations instead of i-nations - I don't believe it has changed much. You can look back before the information age in Europe and still find the same basic elements in society. People with so much freedom that they can travel the world or volunteer in other parts of the world to make a difference. Altruism in other words.

But in many other parts a larger portion of the population are still living hand to mouth and without any safety nets. Simply spreading information about the world to them will cause them to question their situation.

This is likely what caused the arab spring. People in those nations were connected to the rest of the world and refused to accept what previous generations had taken for granted.

However, it's not as bad. You can't practically build another set of power or water distribution grid, but you can assign new frequencies to new operators. There's a limit on how many you can have, but you can have way more than with those services where there is a physical pipe or line to each point of consumption.

I agree that in a thread about Rust systems programming, asking how Rust (and, come to think of it, Haskell) can do dynamic allocation on the bare metal is a good question. I think the good underlying question was devalued by what I think was the poster's lack of reflection. Obviously Rust can do it because Rust is magical, but Haskell? How would that ever work?

Your interpretation may vary.
I too am wondering about this. I thought entanglement couldn't be used for communication because observing both particles simultaneously will reveal that they have opposite spins. It's a conformation after observation, based on what the quantum superposition collapses into once you observe the state. But the actual state is also unknown until you observe it.

I'm not a physicist, but I'm sure there're be one on HN that will tell us what this study really means.

As opposed to the current state of affairs where the West just outsources its dangerous pollution to poorer countries, with health care systems even less prepared to take care of those sick employees?

This line of argument seems to have more to do with nationalism than concern for overall human safety.

Yes, ideally nobody would have to suffer from toxic exposure in the workplace, but the situation we're in right now is that strict Western regulations just lead to more sick people on the other side of various nation-state fences.

Given that, it's not at all clear to me that declawing an institution like the EPA is a bad thing. This pollution is happening right now on Earth, is the US better prepared to deal with it than e.g. Vietnam? Probably. But I'd love to hear some arguments on this topic that aren't essentially nationalistic NIMBY-ism.
The term "simple terms" is subjective and depends on who the audience is.

A popular question to qualify for engineering job interviews is "describe in simple terms what happens when a user accesses a website on the Internet" - The question doesn't give any info on who the target audience is so you never know what level of detail you're supposed to go into. Because this is an engineering question, I tend to go into more detail but after a certain level, you can't really keep it simple because the reader has to understand what things like cache are... Else you will spend 20 pages just writing definitions.

They will mine wherever they can make the greatest profit.

That doesn't mean we will ever run out, or even ever run out of good-quality limestone. It just means that for a variety of reasons (mostly lax taxation laws and a population in poverty that will work for terrible wages) Vietnam is a hotspot for mining in SE Asia, but its total production is a rounding error compared to what is produced in China alone.

There is a lot to be discussed about exploiting poorer areas for resource extraction. It's a subject that goes beyond any one particular resource. But (in the case of lime) it also does not imply scarcity. Keep in mind that lime can be regenerated- the lime cycle is an endless loop.
The real tl;dr is the same as all of these reports:

Stop using coal. Introduce a carbon fee.

Charging electric cars in certain states causes pollution? Stop using coal power plants!

The electricity for making batteries causes pollution? Stop using coal power plants!

A thousand other little industrial processes dump carbon into the atmosphere as it is an uncosted externality from their perspective? Carbon fee aligns everyone's incentives.

The weird hyperfocus on anything vaguely green is absurd when the whole of modern society is running on those same coal plants and carbon squandering.

Wikipedia says:

)
{\displaystyle O({\sqrt[{3}]{N}})} steps. This is slightly faster than the
O
(
N
)
O({\sqrt {N}}) steps taken by Grover's algorithm using standard interpretations of quantum mechanics. Neither search method will allow quantum computers to solve NP-Complete problems in polynomial time.[4]"

I thought there was no way to figure out which interpretation of QM is correct. Can someone explain?
I disagree; the laws are lax because oligarchies in developing countries typically don't get harmed by dangerous working conditions. The people with the power to enforce safe workplace laws have no external incentive; it is at odds with maximizing their cut of the revenue.
