I feel the same way, despite being 'good at math' and having completed the math curriculum for an engineering degree. I know how to use everything, I understand what is being represented and the general structure of the tools I use, but I feel like something is missing. Math used to 'flow' for me when I was in grade school, but somewhere along the way, I think I lost the plot and no longer think mathematically. I am quick to look up formulas rather than intuiting them. I have moments where I completely understand gradient descent for multi-dimensional logistic regression, but they are fleeting and pass with some retarded thought like why does 2 + 2 = 4? I then give up and just implement the parts of the algorithm without keeping track of the broad picture and it feels... dirty. Guh.

Note that guns-for-defense-against-tyranny gun owners are not on the Government's side on this issue. It's the anti-gun nanny-state constituency that is supporting the government.

The group that both guns and supports domestice spying is overlap of "I just use guns for shooting rabbits for fun, and I don't like brown people, and I trust the government", not the groups that says "I need my guns in case the government tries to steal my land."

It depends on what you mean by survive. If you work in an academic context, you will get by with English for work purposes just fine. I personally know various PhD students, postdocs and professors that use only English in their work life. There are, of course exceptions. I could imagine that you might run into trouble in a very small university (as in only teaches brewery engineering) or in a medium-sized university in east Germany.

As to general life, it depends. In population centers you usually always find somebody who speaks English. In rural areas, it might be a bit more difficult. My recommendation is: If you don't understand or can't make yourself understood, just look for somebody below the age of 30 and you will soon enough find an ad-hoc translator.

Nonetheless, if you want to inmerse yourself in the culture and feel "at home", you have to learn the language. This, however, is the case for every place on the planet.
You are mistaken. There are polls which show that the majority of Americans care far more about privacy than fighting terrorism.

Did we need a google tap to find McVeigh?

Additionally, your comment of 'If you think the U.S. is headed in the direction of outlawing alcohol or teaching creationism is all schools, I respectfully suggest you find something different to worry about -- maybe pot... wait, we are becoming more lenient on it as well.' is very nonconstructive. To say that trends do not buck or that social opinion never sways is the height of short sightedness.
He was using an article to note that the sort of high-level strategy discussion was boring or not useful, and that he wanted to see more low-level details into how to run such a business.

However, thinking to those details, I believe that Walmart and Costco actually do a lot of similar things on that front, managing the supply chain and transportation extremely effectively. I think they've no doubt come to the same conclusions on those points. If you want to know them, you could go to any successful large-scale distributor and look at best practices, and I'm sure Walmart and Costco would also be great sources.

However, where costco differs, and where they are special and highly un-boring, is exactly what the original article is about. This is why I felt that asking for the level of detail McArdle requested was not a valid criticism of the article. I felt I was founded in responding to that point.

Wowzers.

Based on data from [http://defensesystems.com/Articles/2011/01/07/NSA-spy-cyber-...], a back of the envelope calculation shows that if the Utah data centre was really storing even a single Yottabyte using SD cards, they'd need 90 floors of servers.

Going off the only public images I could find of the Utah centre, it appears to only be 2 or 3 floors. If this is the case, then NSA electronic storage is at least 30 times denser than current commercial tech.

I agree Dropbox has poor to non-existent customer support. For most paying customers, the support is email only, and it takes days for them to get back to you - if at all. For customers enrolled in their business plan (which I signed up for as a trial), they offer phone support and email support - and I have been waiting for a response for over 4 days (yes 4 days!) to an issue I am having..In fact, I emailed 4 different people at the company and have still heard nothing.

For a company that was recently named "startup of the year" I think it's only a matter of time before a competitor comes along and offers a similar product - WITH reasonable customer service. I personally would be the first to "drop" Dropbox.
Looks like a lot of people commenting didn't bother to read the article:

"Costco does not hire business school graduates—thanks to another idiosyncrasy meant to preserve its distinct company culture. It cultivates employees who work the floor in its warehouses and sponsors them through graduate school."

Note that they do not recruit from B-Schools, but they are happy to send their own employees to graduate school.

In the past, working your way up from the bottom in a large company, being sent for an MBA or MBA/JD combo was a relatively standard thing. Several of my professors/acquaintances have taken this track in Citi Group (I think they got renamed) and the like. Amgen, Boeing, Raytheon, Intuit, etc. (I live in SoCal.) have similar policies and practices where they encourage employees to get a graduate degree (be it Business or Engineering). This is not very groundbreaking and is well documented to be a solid strategy for employee development.

Generally my advice would be to go back to the most basic set of skills you can identify that she doesn't understand and work up from there - including having her construct formula to solve problems (preferably ones that she finds interesting.)

Though, honestly, if she doesn't want to learn maths she's not going to learn maths. If you're really concerned for her and she doesn't want to do something, then you're probably best off just teaching her the tricks and cheats so that she can get a good result and then forgetting about the whole thing - it's not like maths is likely to be a particularly important aspect of her life.

#

With respect to pi in specific -

> Instead of giving her the c=πd formula she wanted so badly, I wanted her to understand that π represented the amount of times the diameter "fits" into the circumference and that this is the relation between the parts of the circle.

If she's never constructed formula to solve problems for herself, she many not know that you can do anything with that sort of information. It's not a trivial step if you don't already know what = and * and / and so on really do to go from any particular instance to c = pidiam.

> I measured as accurately as possible the perimeter and diameter of the mouth of a cup I had and showed her that dividing the numbers produced approximately pi. This unfortunately didn't provide the "ohhh" response I was looking for, which signified that she didn't intuitively understand division.

Try cutting up an apple or counting little blocks or something like that. If she doesn't understand division then trying to use division in any capacity with relation to more complex problems is a waste of time.

> "The circumference of the glass divided by the diameter gave me pi, what does that mean?"

I thought you werne't just giving her the formula? If she were able to substitute letters in she'd have it. =p

Really though. It doesn't mean* anything beyond that pi is the circumference over the diameter. You need other knowledge to network it into before it becomes meaningful.
That seems to be no different than the law applied to any citizen.
I'm continually amazed by the human brain's inability to intuitively grapple with exponential growth. E.g. see [http://rense.com/general87/onetrillion.htm]
Speculation: because the heads of those companies think that surveillance is just peachy and it's their business model? That is certainly the case with Facebook, which acknowledges that they try to encourage sharing and break down norms surrounding privacy, then take the new norms they've created, treat them as a baseline, and extend them further. They think this is good. And it's not like the NSA is going to compete with them for advertiser $, so no bigs.

Is it really black/white: either seek funding or dev? Maybe you can do both a bit. Point 2 already involves two tasks.

Maybe a question helps:
Do you plan to getting funding sooner or later (anyways)? If yes, at what point (dev or revenue-wise) would you feel comfortable to start seeking funding? If no, why do you think you cannot go with #2 now?

Agreed. I also doubt that we'll ever see: John Basil Barnhill: ""When governments fear the people, there is liberty., since poor John Basil had the misfortune of not being as well known as Thomas Jefferson.
First, not everybody will have interest in Math. And that's fine. Secondly, you need to be creative for teaching math, especially at a junior level. I think Lockhart gives a very good insight on this matter - http://www.maa.org/devlin/lockhartslament.pdf

It's important to realize that jr. high algebra is largely syntactic transformations.

a - 2 = 3 is a syntactic transformation of a - 1 = 4.

Most of algebra is taught as a series of syntactic transformation rules. The skill students acquire is learning to apply the right rules to solve a larger problem.

If algebra were taught in a more abstract way, there would be an even more pronounced stratification of aptitude, such that the educational system would not be able to teach to the variety of different levels. At least when it's taught as syntactic transformation, the best students are still largely bounded by working memory rather than intellect.

In Response to Rep. Mike Rogers (R-Michigan)
There are professionals and researchers out there whose job is dedicated to this issue of improving math education (and the same with physics education, computer science education, etc.). You can find great ideas and sample lessons and great educational software.

Math is taught out of context, or completely decontextualized - that's why people hate it, and that's why it's hard to motivate people to learn it. Math knowledge is both situated and embodied. Look at mathematics education research for ideas on how to teach math more effectively.

For example Jo Boaler's work. She is teaching a MOOC on this topic of how people learn math next month:

HHVM is a much, much smaller undertaking than rebuilding Facebook from scratch. Wired did another article from the same source interviews about just how big Facebook is these days: http://www.wired.com/wiredenterprise/2013/04/facebook-window...

Building HHVM was a fraction of the effort, and did not require that we sit on our hands while the competition beat us up during a rewrite.

I'm going through that same decision right now. I'm currently doing an internship at a startup that is allowing me learn machine learning and data analysis in a production setting. Like you I eventually want to do research, but I think grad school is just one way to get there. I'm going to spend another year or so in industry, see if I can make it into doing the kind of research I'm interested in, and if not I'll head back to school.

I see grad school as taking a massive pay-cut over 2-6 years in order to further my education. However, If I can get a similar education while being payed at market value, then there's no competition.
My biggest motivations were having an understanding of the process, and being able to make something original, rather than just downloading it.
"...what things the sister actually likes to do."

There is no more important thing than knowing this. What will this woman-to-be do with this math? Will she be an business manager or an accountant? Will she be a fashion designer or a fabrics engineer? Will she be a naturopath or a chemist? Each of these either/or's has a significant difference in the amount of basic math required.

Once you discover what she loves and is naturally good at, help her follow her path, and then add in math as necessary. Honestly, there are some people for whom cross multiplication will never factor in significantly in life. You may be wasting her valuable time by pushing her in mathematics.
> Then your answer should have been "no". Remember, the very first example is a paragraph, and it asks you if it makes a request for an image, I don't see you getting into the same rage about that.

There's a fairly huge difference between how browsers handle HTML and JS. After fully parsing HTML, the DOM tree is completely built and once resources are loaded, the page is completely rendered. It's declarative. Code is different. No JS interpreter runs a function you define until you call it. So code is parsed and then later on, independent of its parsing, can do things.

When you're asking if code does something, especially in the context of an event listener, it's expected you're actually running the code, regardless of how you've presented it. The HTML equivalent would have been to have asked if opening index.html here would've caused an alert to be shown.

A quiz should be testing actual understanding/knowledge, not intermixing over-literal interpretations and breaking reader expectations. And the wording on the question is still wrong, because as I pointed out, the sans-user-action point is emphasizing the page reload event, not the code itself, so the only logical interpretation is that the resize event happens. Technically, this could still very well happen without user interaction: consider gravity pulling out a display cable and causing the window to be relocated/resized by the OS.

> It's a difficult quiz, no one's expected to get everything right.

Incorrect. It's a deceitful quiz. The delivery is excellent sans a few load-time render issues, but the content needs work.

>>"A politician's worst nightmare is to be the one who was overseeing during an instance in which security disastrously failed (e.g. a terrorist attack)."

And this is the weak link. Also, it is not necessarily the case. As we all know, everything from heart disease to auto wrecks are exponentially (almost infinitely) more likely than terrorism, and just as deadly. Nevertheless, we've accepted these possibilities as unavoidable aspects of existence, and ones we can manage without entering a state of hysterical, paralyzing fear combined with the surrender of all authority to concentrated, unassailable powers.

The thing that can break this loop is a cultural response that turns the person running on a "moar security" platform into an object of mockery. This is the flip side of the herd instinct: few people who want power can stand being laughed at.
If I were to bet on the most significant predictor of arrests during a protest, my money would be on size. The fewer people present in a protest, the more likely that it will be left alone and no arrests will be made. The more people there are, the more likely that those in charge will try to "contain it" through actions that lead to altercations and arrests. I'd say that it's pretty much impossible to have a Tiananmen Square size protest in the US (or any other country with sufficiently advanced surveillance systems for that matter)

You realize that when you get an osx license it says it is only valid when run on apple hardware right? That check, which is named Dont Steal OSX, is there as a pretty basic check kernel extension. They could do MUCH more, this is not going "out of their way".

This isn't that big of a deal, if you're fine with violating the license agreement continue to do so I've no concern. But don't think for a moment that it is a contractual obligation for apple to have their os run everywhere. Ignoring the contractual obligations impacts things like the gpl as well, so if we're happy to ignore this part of the license agreement we need to reflect a bit as far as what legal obligations we want to abide by.
