Your math teacher sounds like a bad teacher. My calc teacher is very much the same, but he heavily focuses on being able to teach us how to learn on our own (i.e. looking up new concepts on khanacademy/other resources, looking for practical applications to theorems we learn, etc.)

"understand it thoroughly" is key. I deal with a lot of programmers who are new to git, and the first thing I always do is to take them through the material in sections 10.1-10.3 of this book. Once a person has those fundamentals (which are not complicated at all), they're most of the way there.

A great deal of the confusion around more advanced tasks (rebasing, etc) is removed when working from those first principles of the system.

Sorry, that is a bit unclear. Essentially, we want to make it easier for people to find issues that many people can identify with, and in the process, show people what some potential solutions are.

By filtering out some of the noise, the ideas that could solve widespread issues can get more resources put behind them and hopefully a greater chance of succeeding.

This might make more sense in the enterprise software realm, but we saw some interest in the startup community as well so we wanted to test it out.
The article makes a case for the immense social cost of advertising. If that argument is too radical for you, let me make another one that looks at the true costs of "free" ad-supported web content and services.

In short, it's a lie that ads give people content and services for free:

1. The advertisers who pay web providers get their money from us, added to the prices of other things we consume. There is no free lunch.

2. The overhead cost of advertising is huge and we pay for that too.

3. We pay the opportunity cost of a product that cannot put users first because ad-supported web providers live or die by giving advertisers what they want (and what we want indirectly and secondarily). This includes both the cost of lost privacy as well as business, editorial and design decisions that optimize for advertising revenue. As has been said, they are using us as products more than treating us as their paying customers. Let me restate to be extra clear: WE are the paying customer, but we don't look like that to their finance department.

4. We pay for all the collateral damage of advertising, such as the tremendous amount of link-bait and other garbage that advertising perversely incentivizes.

5. We pay the social costs. Whether or not you agree with the social costs laid out in the above article, I'm sure most can agree democracy and the free market assume people make voting and purchasing decisions based on facts and reason. Advertising undermines democracy[1] and the free market[2]. Advertising is predominantly about manipulation and deceit. I believe the social costs are the most expensive.

Added together, we end users are paying a lot more for "free" product than if we could just straight up pay for it. And even we non-users are paying the social costs and collateral damage.

Ads are simply a sneaky and dishonest way to get at end users' money without them realizing it.

I recently spent a year as a full-time language student in a college (in China, so more like US high school in many ways) after teaching English for 10 yrs, and also unexpectedly discovered point no. 1, i.e. how tiring it is to sit down all day, and almost never did so as a teacher. Even after 1 year I was still often yawning after 2 or 3 hrs of near continuous sitting, and always got up to walk around outside for 5 or 15 minutes during breaks. Most other students were much younger, usually 20-ish, and often stayed sitting in class during breaks. I don't know how they do it, but maybe it's just their age, or maybe they haven't done a job where they're on their feet all day for 10 yrs.
The money quote to me is this one:

"I was struck by this takeaway [#2] in particular because it made me realize how little autonomy students have, how little of their learning they are directing or choosing."

What strikes me about this is how none of the solutions the author offers fix this problem. In fact, it's unfixable with our current concept of what a school is. No amount of monkeying with how classes are taught will change the fact that the kids are there because they have to be there, not because they chose to be there.
If you are thinking of Blockchain's app, it was removed because it had major functionality that could be disabled/hidden or enabled remotely. They turned it off and hid it when the app was submitted for review, and then turned it on after the app was approved and went live.

That's a major violation of Apple's rules. You have to show the reviewers the same app that customers are going to get.

There are currently several Bitcoin wallets on the Apple app store. Blockchain's was even allowed back.

I don't disagree. In fact, I agree completely with the author of the linked post. The symptoms he writes about are very real, and very damaging.

I just think it's hard to expect every teacher (even fresh ones, 4-6 years out of high school themselves), to remember these specific causes of what made high school a subpar learning environment.
Ask HN: Where to Live in San Francisco Bay Area?
Hi ,

I am from India and in 12 days from now I am moving to San Francisco. I would like to know where can I find apartment in quiet area ? I am married and my wife would travel with me. No kids.
I have been to US in the past and lived in NC. In Raleigh we were renting 1 BR/1 BA for $950.
This is first time we would live in Bay Area.
We don't plan on staying too long in SF just one or two years. We both don't like in US but my company is pushing me a lot to go for couple of years.

I am looking for place that is available up to $1200 rent max. I am aware of fact that rents are extremely high in Bay Area but this may be rent we can afford.

We don't want to live in downtown or in SF for that matter. We are okay to live on east bay and travel to SF. My job will be in downtown. I am okay to travel as much as 25 miles one way.

I am basically looking for place with no drugs , no violence. Neither me or my wife drink.
My wife won't work and will stay home.

I have done some research so far. Here are things I found -
1. Oakland is not so good area. There are some good neighborhoods but drugs and violence and loot is too large.
2. Some advised me to strictly avoid Tenderloin and Sacramento.
3. I don't know about Rockridge. Can anyone confirm if area is good / bad ?
4. Walnut creek is good but very very expensive. How about Concord ? Is Concord good area ?
5. What about Alameda ? Is it good ? Even if I have to pay $100 extra I am fine if its good area.

All other towns that are nice and quiet even though little far ?

Please comment any neighborhoods to strictly avoid.

Thank you very much for reading and helping us !
That's the first problem to be solved.

Apple describes the security features of Apple Pay (and the security features of iOS and Apple mobile devices in general) in the document "IOS Security October 2014"[1].

Of particular interest:

iPhone 6 includes a separate chip, called the "Secure Element", that is used as part of Apple Pay. Here's how Apple describes this chip:

The Secure Element is an industry-standard, certified
chip running   the Java Card platform, which is compliant
with financial industry requirements for electronic payments.

Here is how Apple Pay uses the Secure Element:

The Secure Element hosts a specially designed applet
to manage Apple Pay. It also includes payment
applets certified by the payment networks. Credit or
debit card data is sent from the payment network or
issuing bank encrypted to these payment applets
using keys that are known only to the payment
network and the payment applets' security domain.
This data is stored within these payment applets and
protected using the Secure Element’s security
features. During a transaction, the terminal
communicates directly with the Secure Element
through the Near Field Communication (NFC)
controller on iPhone 6 and iPhone 6 Plus over a
dedicated hardware bus.

The information stored in the Secure Element, which is what is used to actually make payments, is restricted:

Full card numbers are not stored on the device or on
Apple servers. Instead, a unique Device Account
Number is created, encrypted, and then stored in the
Secure Element. This unique Device Account Number is
encrypted in such a way that Apple can’t access
it. The Device Account Number is unique and
different from usual credit or debit card numbers,
your bank can prevent its use on a magnetic stripe
card, over the phone, or on websites. The Device
Account Number in the Secure Element is isolated
from iOS, is never stored on Apple Pay servers, and
is never backed up to iCloud.

The system these retailers want to push, CurrentC, will just be an ordinary app. It will have no access to the Secure Element. Doesn't this considerably limit how secure it can be?

This post seems unrelated to my comment. Did you mean to respond to a different comment?

> He also won a gold medal in the Olympics for boxing so he was not just an ivory tower speculator.

If you are attempting to respond directly to my comment, then I don't see how being an athlete himself (even though that fact seems debatable) somehow means that his ideas aren't coloured in some way by his preconceptions. This has nothing to do with being in an 'ivory tower,' but instead to do with mapping the evidence to pre-conceived ideas and then calling it a day without questioning those idea themselves.

> Meat in those days was regarded as an expensive luxury.

It was an expensive luxury. I don't think that anyone is debating this. Even in China you can map the increase in consumption of meat to the rise of the Chinese middle-class in recent years.
I think, although cannot speak for the person, they really meant CPA, they mention taxes and only a CPA would be legally able to do that.

Standardized tests even more so. Without any actual learning from the class itself, you can generally come close to ace'ing most high school tests by being moderately intelligent.

How do you do this? I mean if a test asks you to solve 3x^2+5+2x=7, how do you solve it without know the quadratic formula or some such?

There is a difference between gaming a test (in the sense of not knowing the material, but still passing) and simply learning the material very rapidly. If you actually know how to do the former, I'd love to hear a concrete explanation of the mechanics of it.
I believe you get a fairly significant discount buying through them.
It actually depends more on what the college is and what the classes. Is it a party school and are the courses in a soft major? Or is it a tier one research university and the courses are weed outs for engineering or medical school?

I was one of those students in high school, and I could see it going either way (thankfully, I took the hard classes and got my act together).
I can relate to this so much it's not even funny. Don't let your fear of failure get in the way. I currently struggle with the same -- applying myself to a difficult task. Staying focused longer than 10 minutes at a time was difficult -- so difficult I was even suspicious I may of had adult ADHD. Turns out that I don't. What I have is the fear of failing and rejection. The fear of exposing my weaknesses to others, and my coping mechanism is procrastination. My procrastination shields me from the possibility of ever failing because, hey, I never gave it my best shot anyway, right?

Hopefully this wasn't too off base, Just thought I'd share as well because I related to this so much.

I wish you all the best!
> Actually solving problems requires a different skillset that can't be accomplished with the "magic" of crowdsourcing.

Maybe so, but the first step of problem solving is identifying the problem. And problems come from people.

(from that comment you referenced)

> Why not structure it as a place for people to complain about inefficiencies.

>The fact that there is a separation isn't actually useful to anyone. You generally cannot edit the view layout without breaking code, and you can't edit the code without breaking the view: They have to be maintained completely in sync with each other

As someone working on a team that practices a good amount of separation of concerns, this is patently false. This is more dependent on how good your template language is than anything, but this separation helps to assure that we're not introducing new bugs or the like.

The main arguments for React along what you're saying is that people seem to abuse the "view model" concept. It's rarely as necessary as people seem to want to make it (though again, dependent on template language).
I wrote a short book recently [1] and went through a similar process. Started writing using Markdown & Pandoc but soon realized that Markdown isn't a very good fit for longer technical documents. As an example, support for asides aka admonition blocks is nonexistent. I switched to Asciidoc + Asciidoctor and the process was much more productive.

Autism is a diagnosis. It might be one disease, it might be 10 different diseases.
this is a bit condescending to teens to write them off as that. Biologically we are not programmed to sit in a classroom, teenage girls are programmed by evolution to do something not too dissimilar to HS (show off their new found sexuality and attract a mate), boys on the other hand are better suited to hitting stuff with sticks. That's exactly the kind of mate you want if you're a teenage girl, someone who can go off and bring nice big juicy protein sources for all those babies that are coming soon enough after flaunting their newly grown hips and breasts that signal sexual maturation.

About the only times that boys get to be what evolution programmed them for is during war time. When boys race their cars and do crazy shit we think of it as delinquent behaviour, but those are the exact same skills that made for the best pilots.

Algebra and Shakespeare didn't feature much in evolution's "plan". Even Shakespeare would rather have been shagging Queen Elizabeth than writing Elizabethan soap operas, but he needed to put food on his table... And let's not forget where Richard Feynman did some of his best work - in a strip club. The modern world sadly is something that will take us a long time to biologically catch up to.
> south (Mississippi) and north (Washington state)

The whole concept of "North vs. South" is an anachronism from a time when most of middle-/western-America wasn't part of the picture. Washington state, while north of Mississippi, is part of the Pacific Northwest, not part of the "North." You'd be in for a rough time if you would expect (e.g.) Washington (state), North Dakota, Ohio, and Rhode Island to all have some sort of a normalized "Northern experience."
I also recommend people to use the included "gitk" tool for visualized repository histories. It's absolutely criminal how most git tutorials never mention this tool.
This is reminiscent of a book called My Freshman Year, by a college professor who actually enrolled as a student at the same school. She writes about numerous discoveries that she found shocking, despite having taught at the same school for many years. It's a great read.

When you are trying to solve a problem which is specific to the country, then I am not sure how very effective would it be for the founders to come to the US, work on something, and try it make it big from there.
I guess YC would need some members who know about the scene in each country. That help would be a lot more effective I guess.
> Standardized tests even more so

Standardized tests are almost always multiple choice. So, given four (or five) possible answers for x, plug them all in and see which one equals 7. That's arguably faster than using the quadratic formula to solve the problem.

And this, in a nutshell, is why my wife and I let our son "online homeschool" when he asked. He's a freshman in highschool and to quote him: "I'm happy to not have to deal with the arbitrary 'lord of the flies' social structure in High School and just be a normal person."

Also a very early symptom; millions of dollars spent on building a (software) product that could be easily developed by a competent guy over a weekend.
It's pretty representative of tons of professional workers I know from many industries and extremely typical in technology companies. Most high quality office chairs are pretty expensive; the Aeron chair that is used at so many tech companies is easily in that price range, depending on where you buy it (and in what quantity).

Maybe the only thing that's slightly unusual is the window.

If your company is not providing comfortable working spaces, then there are plenty of competitors which are.

The real point, though, is that high school classrooms are often downright uncomfortable and unaccommodating. I'd rather stand all day than have to sit at those desks again for long periods of time. (And that'd be a lot healthier, too.)
One could argue that Marx himself felt he was witnessing the apocalypse, and yet here we are.

My biggest issue with this particular take on it is this, "The consumer vision that is pushed by advertising and which is conquering the world is based fundamentally, as I argued before, on a notion of economic growth."

Advertising is not based on growth, it is based on consumption. There is a difference. Let me see if this analogy helps; Survival requires spending money, there is only so much money in the world, once we run out society as we know it will collapse. The fallacy there is two fold, it presupposes that once spent money is destroyed, and secondly that without money society could not operate.

People are, for lack of a better term, actors in a large interconnected system, they both charge the system with work and drain the system with consumption. The 'value' of this system, its GDP, sloshes around from place to place, concentrating at times and dispersing at times. Without its motion, the system stops. Advertising is a means by which actors in the system attempt to get a bit of GDP to slosh their way. They spend some to get some as it were. Sometimes the actors follow along, sometimes they don't. I feel that the effect of advertising on the sloshing around of GDP is a second order effect at best.

Back when my kids were younger the topic of the richest person in the whole world came up. And the obvious kid question, "What would happen if one person got all of the money in the world?" and the answer is we'd switch to barter, instead of buying groceries with dollars we might buy them with traded services. GDP or "production" isn't money, it is something more fundamental than that. Money is merely a convenient accounting system which works well enough for many cultures.
Electronic signatures are replacing all of these physical signing - plus most people's signatures aren't really cursive. A vast number are a letter and a fancy, wavy line. My own 'cursive' is a mix of print and cursive letters. People can be taught to read cursive without writing it if wanted and some people would, in turn, write cursive.

And it isn't dead, but it is dying as the benefits (things like quicker writing, concentration, fine motor control) either aren't needed as much (typing is faster than writing) or can be replaced by other things (games teach concentration and fine motor control on top of hand-eye coordination and problem solving, and that's just the fun games).

Additionally, typing is actually a bit easier to learn than cursive because typing doesn't depend so much on how 'neat' it is. Speed is naturally taught over the years - or at least it was the case for me.
