Is it really that odd? We do the exact same thing with computers. How often, exactly, are we max'ing all 16GB of RAM and pegging all eight cores of our workstations? Couldn't we "just" rent time on EC2 when we need more?

Yes, it's a pain in the butt to farm out most types of compute to EC2. Yes, it can quickly get expensive. Yes, you can save money buying a $40 Sempron. All these arguments and obstacles can be applied just as well to buying a 2-seater subcompact and renting other cars, so before we decry it as "weird" and "making no sense", maybe we should reflect on our own decisions?

Ask HN: Why do we pay for domain names?
There are over 100 million domain names registered, which I'll assume average out at $15/year (being conservative). All said and done, that means $1.5 billion in revenue for the countries and corporations that own TLDs, which were assigned by ICANN.

Should DNS be crowdsourced, with the cost of the domain name accurately reflecting the cost of operating the DNS network? Even at $0.01 per domain name per year, we would still have $100,000 to operate the DNS network.

Is there something I haven't considered, or does the current system need to be replaced?

In that case, can't I just line up a secondary market investor, borrow the cash to exercise, sell, repay the loan and thus get out of the handcuffs?

This is not 2x matching. This is just plain and simple matching. You donate 50, they get a total of 100 - 50 from you, and 50 from the donor.

Yes, the total amount they receive is 2x, but the matched amount is 1x.

I sound pedantic but it's because this is in stark contrast to the Internet Archive's "3x matching" through the end of the month, in which if you donate 50 they receive a total of 200, because the matching amount is triple - 3x - what you donate.

Some architectures write the return address into a register and not onto the stack. The calling function has to preserve it's return address somehow, yes, but that isn't done for you (well, a compiler does it for you, but not an assembler). So if all parameters are passed via registers and the function does not need more memory than the registers provide for the calculation, then this kind of function does not need to access the stack at all.
Unfortunately, just because you hate something doesn't mean we should continue to support policies for wasteful/inefficient transportation.
We live in an era of delicate balance between global overpopulation and resource depletion. We have exceeded the carrying capacity of the planet, we are at peak supply rates for oil and other essential resources. We're rendering things less habitable and global climate change - coupled with water table depletion and topsoil burnout - threatens to crash food crops in some key regions.

It's not a conspiracy. People who know things - and when you have wealth you have the ability to know things - tend to see that we have a period of incredibly instability coming involving a lot of dying and misery. In such a situation having a tight control of the masses and a control of resources in the hands of a tiny elite benefits that elite in ways that times of abundance make seem unnecessary.
Massive profits for the war industry and for-profit prison systems, for a start.
I'll take a crack at being as pedantic as possible. I'm just doing this to play along.

1) "Linear algebra is the math of vectors and matrices" - I think this would be better phrased as "the math of vectors and linear transformations." Matrices are a convenient way to represent finite dimensional linear transformations, but I think it's putting the cart before the horse to say that linear algebra is the math of matrices. This is a minor problem, though.

2) "A vector ⃗v ∈ R^n is an array of n real numbers" - In general vectors are not arrays of numbers, real or otherwise. This kind of definition will run into problems when you get into Hilbert/Banach spaces.

3) "the function f(x) = ln(x) has the inverse f^−1(x) = e^x" - this is only true for x > 0 if we're talking about the real-valued logarithm function, since it's not defined for x <= 0.

givewell has an article on how lots of donation matching is actually closer to a restructuring of a large donation from another donor http://blog.givewell.org/2011/12/15/why-you-shouldnt-let-don...

This looks like it fits that category -- donations are matched up to $118,569 which really just means someone is donating $118,569 and using that donation to attract more donations. If you think it's going to hit that cap without you, you haven't given anything up. And if you don't, you still might not have given anything up, since the donor still might give the $118,569 they were willing to give anyway.

They also detest the democratization of wealth, which invariably results in some form of "sprawl." It's either the horizontal sprawl of endless little palaces of Versailles with their little lawns, or it's the vertical sprawl of monstrous energy-sucking megastructures full of luxury condominiums. But in either case the result of democratized wealth does not give fellatio to agrarian-utopian fantasies.

Programming isn't only one skill, though, any more than writing or math is one skill. I think the point of elementary school is teaching enough basics that young people can navigate an area of study, have a good idea of its breadth, and decide whether they want to come back to it when they have more latitude about what they would like to study further. It also helps in business and citizenship, so you have an idea of what to pay for stuff, and you know what you're voting for.

>we can't have elementary school classes for them all.

We not only can have elementary school classes for it, we do, and have since I first walked into one 32 years ago. That fact is responsible for a large percentage of the programmers walking around today.

>we need to address the current holes in our education system before we start adding new course work

In my opinion, weakness in math (and programming) is one of the current holes in our education system. I'm also trying to argue that this is not new coursework.

> Rail transit is always betting on the future rather than today.

Agree! But it's too late for Bellevue. Its low-end houses are already $500K. It'll take $billions (including plenty for lawsuits) and decades to get stations within walking distance of most people. Better to install next year a more flexible "subway" consisting of buses (Rapid Ride as it should've been).

The plan is for Bel-Red Road to become an artsy light-rail corridor, with densely packed restaurants and condos. When that becomes reality my kids will have mostly only 2 choices: a tiny condo for $500K in today's dollars, or a junky 1950s house for $1 million+. And the city will be a lot more crowded than it is today. I don't think Bellevue will be livable at that point. That's not all the city planners' fault of course.

My go-to example is Montreal's Metro system. I like how they use long buses so there's no loud squealing of metal wheels on rails.

>If someone were to write and (crucially) popularize a version that reads the way people explain Foucault, things would be different.

Foucault was French. French (and Europeans that are non British in general) do not write theory and history the way anglosaxons do. At least most of them doesn't. If you want to learn from them, you have to study their idioms. You cannot just point at it and say it's unquotable or alien (or, well, you can, but it's not fair).

It's like living all your life in C like languages, and being put off by functional programming and parentheses in LISP or Scheme. It's another way of doing things. If you had started with that, you'd find it perfectly normal. Since you didn't, it takes some time adjusting and absorbing the material and culture.

For me, a European, those are perfectly fine and understandable. And I also understand the use of metaphor and poetic language they often use to make a specific point. The anglosaxon idea for that is that you should write in a way that the local butcher or stock brocker can also understand -- which constraints you to only writing for issues that a stock brocker can fathom (or only handling extremely elaborate issues at that level of discourse).

To put it in programming terms, the anglosaxon way is like the C way -- they don't like "magic", unfamiliar notation, higher level code, and DSLs. And they feel that "worse is better". Which, I guess, makes the European way more LISPy.
Regarding languages lacking certain features therefore limiting the cognitive space of their speakers, everybody should remember the English has no future tense: http://itre.cis.upenn.edu/~myl/languagelog/archives/005471.h...

> the Braves Stadium move

Wow, first I'd heard of it. I mean Turner Field is all of 16 years old; probably time for a new one. At least that should alleviate the summer downtown congestion, though I don't believe 285/75 really needs it. There's a section there that I thought I counted 9 lanes. Using City-of-Atlanta logic, I guess it's time for a 10th one, eh?

More on topic, will Cobb now allow MARTA to extend up there now that a stadium is coming?

(from article)
> Reed concluded his statement by saying he is “excited” about potential future uses of “the land that is now Turner Field.”

Really. Can't wait to see what he's planning, b/c damned if I'd ever call that section of town exciting.
Very cool, but I'm not sure where the article got the 8,800mph number. From what I understand the Earth relative speed is around 23 or 24 thousand mph.

Edit: the referencing article at http://www.nasa.gov/jpl/juno/juno-earth-flyby-20131210.html#... says it got an 8800 mph boost.

Bitcoin is continually referred to as "anonymous" in the press, but it is just the opposite [1]. Maybe confusion over what cryptographically secure identification is? Some simple network analysis on the public ledger can reveal a whole lot of "identifying" info ...

[1] http://bitcoin.org/en/faq#is-bitcoin-anonymous
Yep. I've used Zipcar in lieu of a car before (and now own a car that I use maybe once every two weeks), but there was just enough friction due to having to walk to the nearest available car (the closest location to us wasn't always available, so we'd have to walk a few blocks further for the closest available car), having to pay for the time when the car is just parked at your destination before you return it, and not being suitable for the kind of longer range, weekend or week long trips that are a lot of what we need a car for.

If the cars were self-driving, however, that would solve the majority of those problems. No need to hike to find the closest car, it would come to you. No need to pay for the time that it's parked while at your destination, it could be used by other people, and another car could come pick you up when you needed to leave. No need to return the car to where you picked it up, it would just go back to the closest available station and they'd rebalance themselves automatically.
This looks like such an amazing product. This gives you all the benefits of having selenium/capybara/zombiejs without the huge maintainability headache.
- Self-driving cars will still need to park at off-peak times. Unless they just keep driving in circles.

- Having your car park 10 miles away from you after every trip adds some forty miles of travel per commute. That's forty miles of fuel and forty miles of maintenance, every day.

- I'm also not thrilled about the prospect of already-dense cities shrinking streets to one lane. We call them concrete jungles now- can you imagine if all the roads were only 15 feet across? Goodbye, sky.
The following page estimates the true cost of car ownership at approximately $1.38/mile: http://commutesolutions.org/external/calc.html

That's still quite a bit cheaper than taxi fares or the minimum $2.75 that Uber charges. Assuming that you spend $20k on purchasing the car, you'd make up for the cost of the car in just under 15,000 miles driven compared to taking Uber at the quoted rate.

> School is there to show kids how to teach themselves anything they want to learn. Not to spoonfeed them specific skills they may or may not want to have.

Eh, debatable. I'd tend to say that ideally school is there to give kids experience with a wide range of activities and to try to inspire in them a love of learning in at least one of them, as well as the basic methodologies of doing so.

I don't think spoon-feeding, or making people learn skills they blatantly don't like, has great returns. But I wouldn't go quite so far as saying school's just there to show them how to learn - considering how directed the learning environment is, school doesn't really seem to spend much time on that at all.

Ugh, I hate these sort of comments. It's as if bitcoin is only an exercise in speculate supply and demand. People, there is a huge network and protocol that's behind this thing! It's not just about the currency everyone's trading, it's about the underlying network! There's a distributed registry that anyone can look up. There's a source of truth for every single bitcoin (and future uses thereof) in existence. There's a reason network difficulty trends with price.

No, bitcoin is NOT just a bunch of traders trading and no, that's not what's going to give you an understanding bitcoin. That's like saying that understanding how a computer works is just by watching the monitor. There's an underlying fundamental, dare I say, intrinsic value to bitcoin that gets ignored by almost everyone fixated on bitcoin the currency's price when the real interesting thing is in bitcoin the protocol.
I'm not saying I could have, but I would expect anyone making a definitive claim that it's a bubble to also produce a testable hypothesis.
As a life long ATLien, I want to know when Atlanta was walkable, and if it could have even been considered the same city as it is now. For those of you who don't know, the population of metro Atlanta more than doubled between 1990 and 2010.

Yes, all types of transportation suck in Atlanta, but roads and cars are an extensible, scaleable solution with most of the costs being marginal as opposed to fixed, meaning additional demand can be handled easily. Like others have noted, you offered no real solutions to that problem. MARTA is kind of a joke of a system for anyone that values their time. A trip on MARTA will take about twice the time it would take to drive in a car. At the average commuter distance, you recoup the cost of buying a $5,000 car in a year if you value your time at minimum wage. If you actually care about fixing the problem, fix the economics of alternatives. Don't just go about complaining about the fact that you don't like not being able to walk where you want to go, suggest solutions.

And please try to consider this problem outside of the perspective of being a student, because that honestly seems to be the only perspective you've given to this. A lot of the vehicles you see in Atlanta are work vehicles, and that mobility makes a lot of things possible that you probably are a fan of. You may want to consider the dynamics of the local economy further.

Honestly, I have to say this article isn't up to the standards I'd expect of a fellow Tech student, particularly a PhD candidate. You are very well intentioned and undoubtedly intelligent, but simply pointing out what everyone knows isn't very helpful. I'll be interested to see the future posts you promised.

convince me that 800 pages is worth it (reviews so far haven't).
Most of the addresses of the bitcoin rich list belong to bitcoin companies. Not necessarily individuals.

The article fails to compare this with gold distribution, for example, to create some context.

Nevertheless, at some point those large holders will cash out to buy companies or property and, in the long run, the currency will become better distributed than say the dollar, because of the lack of easing that goes directly to the wealthy and big bankers pockets.
