This sort of happens already, at least for families that are economically empowered. My spouse and I paid a premium for a house in a neighborhood that has good schools. Most of the parents in the school area have college or higher degrees.

In some other states, parents just put their kids in private schools.

This kind of economic segregation, in addition to kids receiving considerable support at home, can make it seem to those who only experience middle-and-above-class society, like education is OK. We do the same economically as we always have, because the underclass have always been the underclass. While this hardly seems moral, it has become more alarming since it seems like the underclass is gradually expanding.

It doesn't help families who care, but who can't afford an expensive house. Also, someone could really care a lot, but they are still at a disadvantage if:

1. They are a single parent working two or three minimum wage jobs to make ends meet, and just can't pay as much attention to their kids

2. They don't have the experience or the network of friends to help them deal with situations when things aren't going well enough at school, and their kids end up falling through the cracks

In my view, dismissing / blaming families for the condition of schools becomes a self fulfilling prophecy.
Yes!! I love that!

I'm not too familiar with the internals of OSX, but I would be very surprised if that ram is actually really used. More than likely, it's just caching of things already on the harddrive. If you have a old fashioned mechanical drive it makes a lot of sense, but with modern SSDs, I doubt you'll feel it much.

Unless you're a true poweruser, no one really needs more than 8gb by todays standards. I have 32gb because I maintain and develop 4 different codebases each with their own setup in different VMs. If I didn't do that, I could manage with 8gb just fine.

1. I think that number includes private money.

2. Comparing salaries across countries is not that useful - teachers aren't going to go to another country to teach. But they will go to another, higher paying job near them. So the more meaningful salary comparison to make is with the amount of education and work-time a teacher needs, how much do alternative jobs in the same area pay?
It's not that they use them all, just as you work you keep adding more tabs and there's no GC for tabs.

Caveat that I might be completely off, but if, say, 10 bn people tried once a nanosecond since the inception of the universe, you'd still have only 10^10 * 2^86 ≈ 2^33 * 2^86 = 2^119 attempts, that still only cover's 2^-9 (i.e. 1/512th) of the total addressable 2^128 space, i.e. still fairly unlikely that you'll have hit that specific number.
I feel it's definitely the SSD. In the summer of 2012 I purchased a MacBook Air with SSD and it always felt a bit more snappy than a MacBook Pro purchased at work in the same summer. RAM was equal, so the difference was that the MacBook Pro was not packing an SSD.

What didn't you like about the rMBP? I'm very pleased with mine. It's about as portable as could possibly be necessary - I carry it with me a lot during the day and it's way small and light enough. Of course, I would love a longer battery life, but I get about 8-10 hours which is ~ a day's work, and I'm always close enough to a power outlet.

Unless you're working with the laptop in one hand or using it regularly on journeys > 8 hours, I can't see much of a difference between Air and Pro.
The widespread irrational disgust shamelessly expressed here, without regard for how expressing that disgust out loud is enforcing the status quo and contributing to the prevention of this ever being accepted in the mainstream, is exactly how I imagine the pervasiveness of homophobia in past generations.

I've been avoiding mentioning ASICs since I've been defining the category I'm talking about as excluding them. Chips for sound cards definitely fit in the ASIC category as I count it, and have plenty of company. E.g. chips for DVD and now Blu-Ray players. The first generation of OPPO player I bought included an FPGA running licensed Anchor Bay IP, the volumes they anticipated selling didn't justify an ASIC.

Game consoles are a pretty good example, although how often do they adopt truly novel stuff vs. taking off the shelf CPU and GPU IP and making their own customized and cost reducible versions?

The PS-3's Cell is an interesting case, the effort certainly had ambitions beyond game consoles.

I'd argue it and the Amiga (the first PC I thought worth buying) are examples that prove this posited rule of general purpose beating specialized, both were in the end failures.

Sometimes you can find accompanying audio or video recordings from that semester or from a different sem (UC Berkeley does this), and personally following along with a lecture sequence makes studying advanced topics much easier.

Well, I consider BBC to be the most reliable source of news there is, and they went to a NK university and experienced this themselves:

http://www.bbc.co.uk/news/world-asia-25945931

As for "personal experience": I come from a country which used to be communist, and when you wanted to make a telephone call, you had to go to a nearest post office, ask for access to the telephone, and first they would connect you with an agent who would listen in to what you were saying, and only then you would get connected to where you needed to call. Everyone knew about this surveillance. I have absolutely no reason to suspect that NK doesn't do the same thing.
I never really understood the reasoning behind the whole "maybe your email or password is wrong - but we wont tell you which" message that websites love to give.

The reasoning tends to be along the lines of "prevent spammers getting emails" and "security by obfuscation".

But almost all these websites have a sign up page, and if the email address is already in use they will happily let you know that.

Therefore if a hacker/spammer/bad guy wants to brute force your application for emails - they can just use the 'sign up' page to get the emails instead of the 'forgot password' page.
I once stood in line at an airport for an hour to pass through a checkpoint watching an entire large pallet of boxes marked "bakery goods" go through a pass through lane without any checks of any kind. It doesn't surprise me that workers don't go through security checks because it's "too hard". Why would you lock your front door with 5 locks and then leave your back door wide open and claim your house is secure?

It doesn't matter if it takes 1s or 10s, but that it takes 10s every time (to verify a password, for example)
Every now and then I carry out my own manual garbage collection of tabs: iterate through, copy URL of any I don't really need right now, collect the URLs in a text file somewhere. I usually end up losing the text file but no disaster ensues.

I'm currently running with 19 tabs open. Any more than that and it becomes too difficult to identify them. Ideally, I try to trim it down to about 10 when I can. How anyone can be even remotely productive with 300 open is beyond me.

Out of curiosity: Are you looking for any casual code contributors? The main ideas behind the site (automatic anonymous account, "slow" web kind of thing where you only see updates once a day, possibly seeing some interesting thought-provoking stuff each day) are actually pretty interesting, and I think I'd enjoy helping out with what you're working on. I have a job and my own side project(s), so I can't say I'd be really in the nitty-gritty of the project all the time, but maybe I could help out here and there.

I would understand completely if you don't want a random stranger on HN touching/seeing your code though :)
This time around it's the opposite, the Pro line has been creeping towards the Air line (from TFA): "The 13-inch MacBook Air and MacBook Pro aren’t that different—$300 gets you an extra half a pound, a Retina display, and a processor that’s an awful lot faster."
Why Am I Paying for Your House?
And a separate power connector.

This is the biggest issue with this Air - that if you want to charge this laptop and use anything, even a USB mouse with it, you will need a usb adapter with power pass-through. It's just stupid. They should have left Magsafe 2 on it + USB-C, or at least 2 USB-C ports, so you can use one for charging and another for video/data.
With respect, you already said you (personally) couldn't identify subject mastery any way other than written tests. So this comment is simply a tautology.

You don't believe you can identify mastery any other way, so you don't identify it any other way, and so you believe that testing is the only way to identify mastery. OK, but this circular logic is broken.

You could show subject mastery by creating anything, or performing anything, or explaining something verbally to someone else, or by earning money in that field. Writing answers to test questions is rarely a relevant skill and more often tests whether you were told about the exam's quirks rather than mastery of the subject.

> Unfortunately, WebGL hasn't been updated in a while and it is badly outdated

WebGL implementations have a lot of trouble coping with WebGL 1.0 still. It's slowly approaching "ok to use" status.
A large portion of web users have no WebGL, or a sw-only version of it (SwiftShader in Chrome). This with a 4 year old spec.

With more frequent spec updates WebGL would have lost all credibility due to mismatch between spec and reality, and variation in implementation quality.

Mid-range microcontrollers is actually where the Forth chips thrive, so I would not be so sure.
I don't know if this was at all on the author's mind, but by implementing the GUI in WebGL vs. DOM, they can now composite the GUI with the scene, rather than the GUI being strictly limited to the front of everything 3D. It's why I wrote Primrose[1], as source control editor that renders to Canvas instead of DOM. I intend to toss these things into 3D space.

Note that -l is also an extension, just a BSD one.

The only options in POSIX sed are -e, -f and -n (and -e is usually cargo-culted by people who want -E. -E being a BSD extension enabling extended regular expressions — -r in GNU sed)
One option would be to make the power adapter fancier. Instead of just being a box with a wall cable on one end and a MagSafe cable on the other end, what if it had USB and Thunderbolt ports? You would have the same amount of gear to carry around, but the actual laptop could be thinner.

Here is the recipe for guaranteed "gambling" success, from the linked to article. Quotes used, because it is not gambling, since profit is guaranteed by the odds (ie. you are effectively part of the house):

http://www.afr.com/p/national/no_humbling_great_gambler_1Rah...

It is a great system, although the smartest aspect of it was not the maths or computers. It was the psychology.

As former card-counting blackjack players, Walsh and Ranogajec knew the house will always seek to maintain its advantage.

In its crudest form, this involves barring those who become too successful. And so over the longer term, being able to stay in the game becomes almost as important as winning. For the syndicate, that meant being “with” the house rather than against it. In both Keno and “parimutuel betting” via the TAB, the house can’t lose, as it takes a fixed percentage of the overall pool.

And so by pumping huge amounts of money through Keno and the TAB, the syndicate was inflating the profits of the house rather than taking money from it.

It was a symbiotic relationship, but one that neither side wished to publicise as it was ordinary punters who lost out. For Walsh and Ranogajec, their Keno exploits in Tasmania were hugely ironic.

In other words:

1) Pick a game where the jackpot accumulates, for example, the "Jackpot growth pool" in Keno, and the house takes a fixed percentage of turnover.

2) Cut a deal with the house for a rebate that swings the total odds (including the accumulated jackpot) in your favour.

3) Gamble as much money as possible, so you have a significant chance of capturing the accumulated jackpot before anyone else, thus reducing the odds of an average punter winning an accumulated jackpot.

4) Effectively, you will be acting a a proxy for the house, allowing it to reclaim jackpots (via their percentage on your turnover), that would otherwise go to the average punter, and collecting your own percentage for your trouble.

The house makes a profit on the additional turnover that you generate. You make a profit by collecting jackpots at odds+rebate that guarantee a net payout. The average punter loses as they are unlikely to win the jackpot before you do, so their average payout is reduced.
Of course.

In other "news" the FBI has never found one single shooting by any one of their agents to be in the wrong.

Never, ever. Over decades. They have perfect people.

> When away from a power socket, I use Safari instead of Chrome. Saves battery a LOT.

Were you comparing Safari with 0 extensions vs. Chrome with 0 extensions? Or does each have a different extension load?

I will often fall back to Safari if a page doesn't render properly in Chrome, but that's because I installed a bunch of extensions on Chrome and have consciously left Safari pure as the driven snow. It's a different problem domain, but I know certain extensions can use resources in surprising ways.

Why would you lock your front door with 5 locks and then leave your back door wide open and claim your house is secure?

Because locks serve two purposes. One is to make your house secure. The other is to tell other people that security is important to you. What happens at airports is entirely about politicians telling the public security is important to them. It has nothing to do with actually making anything secure. Schneier's term "security theatre" is completely appropriate for what happens because you're not supposed to look behind the scenes, or you'll see how fake it all is.

What's stopping the monitor from charging the laptop? The spec affords such things.

How cool would it be if every monitor in the future used the exact same type of connector and also doubled as a power supply for anything connected to it? Same thing goes for ethernet.

I would argue that registration pages should not let someone know if an email is in use - if a duplicate email is used in registration then the site should just send a quick email notifying the user that this email is already in use (with sensible DOS protection and email opt-outs etc.)
