Response spectra of human cones: https://upload.wikimedia.org/wikipedia/commons/thumb/0/04/Co...

The medium ("green") and long ("red") cones are pretty close and similar. It's interesting that the diversity of reds and greens we experience are computed from two mostly-overlapping signals having peak responses at roughly "leafy green" and "sunny yellow".
When I first started doing weights, my father and his brother both drilled one piece of advice into my head: training too much is worse than not training at all. After reading this article, I'm grateful for it!
Man, I got used to the kickstarter campains that try to sell me hot water and make it sound like it's the greatest thing on earth.

This is refreshing, it's simple, clever. A true hack in the best meaning of the word.
Scored 10 (for comparison: male, age 20-29). I think the score might be better on a real monitor (now on notebook) and worse on a phone/tablet, because the high-contrast on some notebooks (my Vaio Z for example) and phones (AMOLED type) might decrease the differences between colors on these charts.
The 8000 SEK/withdraw is only for ATM's located at the bank, and are been general dedicated to that banks customers. Bank ATMs has slowly been phased the last ~10 years with general ones (any custom of a bank can use them), and those has been spread out at malls and other similar places. Those however do not have an 8000 SEK withdraw limit, but rather around 1000-2000 SEK. ICA was one of the earlier adapters of those ATMs, and others has slowly followed suit.

However, I think you slightly missed my point. I do not say that Sweden is worse than the US. I merely wanted to point out that banks actually put in some real restrictions for taking out cash from ones own bank account. They are not holding my money for safe keeping, but rather providing a service where my money goes in, and I can get some out under circumstances they dictate, and only if they agree with it.
Holding them to term is actually a bit of a joke if you think about it. The Fed is buying bonds. The government is selling them. As long as the Fed keeps buying them, the government can keep selling them. If the Fed holds them to maturity, where will the money come from to pay back the mature bonds? From the government selling even more new bonds which the Fed will have to buy.

It's not a Ponzi scheme or a pyramid scam but it can't help but be compared to them. It's in a similar boat to Social Security. It has the veneer of legitimacy because "it's the government" but underneath it's a bit unseemly.

1. How do you get 8ms? The stopwatch only shows centiseconds.

2. You probably mean minimum, rather than maximum.

3. I got that down to 0.05 s (50 milliseconds) by using two fingers on an iPad. That took about 30 seconds, and I also got a .06 in that time, so it probably can be improved upon.

wow, thanks for the realistic perspective. it is as if some journalists don't do any actual work while complaining that blogs are killing newspapers. it's great that I know he built his own wooden structure when he was young, but the fact he hasn't updated lectures in a decade or is poking fun of Hillary in class material is no ones business.*

EDIT: *Something we should have been told about by the article as it's a key part of character
If you watch the videos in the kickstarter and on his site, you'll see he removed a ton of parts every other printer has to have. For example, the Z axis is now water...that's a lot cheaper than all the parts you need for a bed and the precision motors to normally raise/lower a platform. He did this in quite a few areas, which quickly plummets the price.
Irrespective of whether or not he was highly specialized in some aspect, he had demonstrated a much broader potential to learn and adapt; more than the specialized people they would otherwise be hiring.

So it seems like the real reason he wasn't hired was:
1. They might have to pay him more, for his potential (as illustrated by his degree) than they needed to pay some other fellow they could hire.
2. The HR management doesn't really know what to do with smart broadly skilled people. They have well-defined slots for cogs, but generalists are tougher to manage... you can't just shove them into a predefined slot.

To me, al it proves is that the industry is not ready/willing to hire a possible generalists (who also happened to have proven that they can learn something and be good at it). The cognitive dissonance making them think that he was "highly specialized" might also have been a possible contributor.
It's not for them though. It's just data science competitions that anyone can enter.
So only punishment for the fraud (of masking the country of origin, adulterating honey with banned antibiotics, rice molasses and such) was one year of jail for two executives, who were declared rogue by the company after their arrest. How will you deter future frauds then?
Many areas already deal with extreme temperature variance, the only change will be which areas need to do so.

And exactly how fast do you think the overall temperature is going to change? All the predictions I've seen have been single digit degrees per century.
It should be mentioned that it normally only occurs when well trained people stop working out for a couple of weeks and then get into it again at full speed.

If you are used to working out hard, you won't get rhabdomyolysis.

So if you're pretty fit but stopped working out for a while, get into it with moderation!

To everyone else: don't be scared of rhabdomyolysis and work out!
That's not true at all and hasn't been for a long time. Maybe if you're mixing more than 8 tracks on a low-power CPU, but even a chromebook can do that sort of thing. Even my phone (several years old) can do that. Playing back stereo audio (which all that's required here) is something that can be done from a device that fits on your keyring. What you're arguing hasn't been true since the 90s.

Certainly, it would be bad if this thing relied on every last available bit of audio bandwidth all the way up to 22.05 Khz, but there's no particular reason to do that.
Interesting. I should point out my experience with this is from about 18 months ago (Spring 2012).
Because there is no predictable upper limit, and any quick fix is at immediate risk of not being enough shortly later.
Last time facebook was doomed they managed to set an all time stock price high by getting their shit together.

Google has been public for 9 years now, facebook is just over a year. To call them doomed because they seem intently focused on controlling their rollercoaster stock price seems a little short sighted. At least give them the chance to get their house in order before lambasting them for not spending enough money on trying to make people live forever.
The icy tundra areas mostly don't have good soil. Even if they get the temperatures of the American midwest they will not produce nearly the same calories/year/acre. So even if populations could all start migrating north (without somehow triggering world-spanning conflicts as millions of people get forced across national borders) their food source won't be coming with them.
Before I was a developer I was poor and worked as a busboy and a dishwasher for several years.

At one point I mismanaged my finances and completely destroyed my credit score, as well as getting listed in chexsystems for overdrafting a bank account and not being able to pay them back for several months.

To cash my paychecks (I got paid mostly in tips), I used a check cashing place or the grocery store. I did this because being listed in ChexSystems prevented me from opening a bank account.

Once I became I developer I dug myself out of debt and then rebuilt my credit score. Eventually after waiting long enough I was able to get a checking account from a bank that used FICO scores instead of ChexSystems.

The article is a bunch of crap. It reads just like that nickel and dimed book by Barbara Ehrenerich[sp]. How an academic cannot figure out that the reasons these poor people are giving for not having a bank account is false? There is one reason: they are listed in ChexSystems and can't get an account.

Do you not consider Cyprus a developed country? Just a few months ago, many of its citizens had their deposits garnished, some at rates of 40%. How about Greece? There were talks of doing the same there.
Ha, glad I wasn't the only one. I feel less stupid now.
7, among the highest for my cohort. Although it's possible the sorting heuristic I used helped, basically a loose binary sort followed by closer inspection and comparison of proximate squares. Increased the zoom level of the page to get a bigger sampling area for my eyes.
The resin takes a certain amount of light exposure to fully cure. I doubt that noise or buffer glitches would seriously cause a noticeable effect on the print. More likely, soundcards with improper equalization, and galvanometer impedance and group delay would be the cause of shape distortion.
3) "Free checking."

And then, even if you (the low-income person) avoid the overdraft fees, eventually monthly fees start appearing. So far, in 10 years of using banks, I've twice closed checking accounts because they started charging monthly fees. I might try a credit union next time I need a bank account.

Keep a $3000 minimum balance or have a regular job depositing money into your account electronically, and the monthly fees disappear. Banking is, in absolute terms, too expensive for the poor.
They are under extreme pressure to continue purchasing treasury bills from the government and mortgage backed securities and derivatives from banks. Even hinting that they'll start tapering these purchases has caused the equity markets to drop and rates to rise. Actually tapering will in short order throw the country into a recession. I'd be hard pressed to call that "complete flexibility."
No, but it happens, in any school at any degree level there are people who "pass" who shouldn't. Even in my lowly engineering school ( graduating class of Computer Engineers was maybe 30 ) there were a number of people who should not have been given a degree, but since they fulfilled the basic requirements they were. Those were the individuals who were looking for jobs after graduation. A majority of the people had jobs well before their senior year.

I am not saying this guy is a slouch who got what he had coming to him, I don't know him. I am saying that no compelling argument was made that this article was anything more then conjecture.
It stunts other countries too. Aggressive protectionism affects those who want to sell to America, although this probably isn't of too much concern to Americans.
I think it's perfectly reasonable to postpone worrying about 50+ degrees until it's already shifted at least 5. If it turns out 5 is terrible, we'll have hundreds of years to implement plans to stop 50.

If you think 5 degrees is catastrophic, then sure worry about that in 2013. But it won't make the planet uninhabitable.
It looks like the resin they are using is "Makerjuice" (http://makerjuice.com/). I don't know anything about that resin though.

FWIW, I'm interpreting this as "ashamed to admit you haven't read this title yet" as opposed to "ashamed to admit you want to read this title".

Good old jingoism ... and nepotism towards his friends, Kurzweil. People like Gruber and Wadhwa should not hold so much sway with normal masses. Just read these two sentences.

"Google already reads my emails before I do, and, by analyzing what I search for on the Internet and which Web sites I visit, knows what I am thinking. It “knows” what other people think about me. If my friend and noted futurist Ray Kurzweil succeeds in his mission at Google, it will understand my wants and needs too. It will predict what I want to search for, where I want to go to, and what I want to eat. It will understand how my brain thinks and become my personal assistant."

"Contrast this with what we can expect from Facebook: more ads, more annoying sponsored posts, more intrusions of privacy. "
Awesome idea. But isn't mirror inertia a problem?

Also constant velocity of z-axis movement might pose some inefficiencies because if you want to print a box you have to set the rate of ascend low enough for the laser to create full bottom and you can't speed up when you are building sides of the box.
Well, that's nice and all. But how fit people and everyone else are supposed to remember that?

I like your call to arms and encourage you to both be angry and participate in the legislative process. But, the US imported $82 billion dollars worth of agricultural products in 2010 [1]. This makes the US potentially dependent on foreign nations for basic necessities. Preventing the loss of self-sufficient food and agriculture production, at a level that will provide for the population and keep prices reasonable during a crisis, is an aspect of national security.

It's not clear he was trolling - there are people who genuinely do believe all that stuff about the poor deserving it and completely fail to grasp the advantages they themselvse have.
Microsoft implements Dual_EC, but does not default to it.

CTR_DRBG is just a block cipher in counter mode. I don't think it's a scary construction.
I'm not talking about 'can you play back audio', I'm talking about 'can you play back audio with zero glitches'. This becomes a problem of scheduling precision, whether or not scheduling will 'stall' if a driver hangs while processing an IRQ, whether or not the graphics driver has a potential to hang due to a rendering operation, etc, etc. These are all a reality on modern desktops even if they're fairly rare (I don't think I see audio glitches on my desktop more than maybe once a month).

The people I talk to who do professional audio recording and mixing insist that it is still a difficult problem; it was back when I did mixing (early to mid 2000s, not 'the 90s'). The prevalence of custom APIs for glitch-free low-latency audio playback like JACK and ASIO suggests to me that you still can't rely on just feeding samples to the OS and having them come out of the sound card at the appropriate rate 100% of the time.

FWIW, Windows introduced an entirely new audio stack in Vista that was tuned specifically to address these problems. Their first iteration managed to cripple ethernet bandwidth because of the scheduling requirements imposed for glitch-free audio.
Same here!

Re: the suit-and-tie thing... I am a dev doing interviews now, and where I grew up (blue-collar midwest), wearing a suit to an interview is a sign of respect, so I've been doing it... not a good idea?
Thanks for the points on how trivial it would be to handle line noise and playback glitches. Makes sense to me; I just don't know my hardware and analog circuits well enough to know how cheap it is to filter that stuff out.
It doesn't work for ACH transfers though.

We New Zealanders are so in awe of this BS technique that we showed off our copy to our US overlords with the Dotcom raid. Unfortunately we neglected to make the techniques used legal first, so the drawn out court process has been a bit painful and compensation payouts to him are likely.

Last time I did this I was using a MacBook Pro (very nice monitor), this time I'm using a Thinkpad T61 (lousy monitor).

I scored the same both times.

I'd be interested to see what happens if people use poorly calibrated monitors. I could tweak a screenshot with the Gimp, but I don't know enough about eyes to know if I'm making any meaningful adjustments.
I've got dozens of pieces of Cisco gear deployed throughout my network but I'm far from a crypto expert and, honestly, haven't really kept up on this specific issue so perhaps somebody can help me out here.

Within Cisco's operating systems (primarily IOS, but also NX-OS, IOS XR, etc.) I can think of a number of places where hashing and encryption are used: password hashes (obviously), BGP passwords, OSPF authentication, NTP secret keys, etc. Which of these might potentially be affected if Cisco were using this algorithm? Any of them? All of them? With the exception of being able to specify particular types of hashes for user passwords, I'm not sure what else one might do to mitigate any vulnerabilities.

Edit: After thinking about it for a few minutes, I realized that since the processors in Cisco devices are already so slow (relatively speaking), Cisco would likely avoid using such an algorithm when other, much faster options are available. I can't be for sure, of course, but it seems reasonable. In the meantime, I'll keep my tinfoil hat on.
I'm also a huge fan of MDN. Fun fact, if you use Duck Duck Go you can add "!mdn" to constrain your search to just MDN. It's now my #1 way of searching for HTML tag properties and CSS syntax.
I would bet generalists are going to be selected against. It's good to have a few generalists to handle the unexpected and such, but at least to me it seems you'd wind up paying the generalist more for the same work, so you would seek to use specialists wherever possible.

I am really surprised to score 0, especially as I'm not an artist.
I mainly browse HN to read good/stimulating discussions and submissions, to expand my knowledge, to see other users' reasoning, to develop and maintain a improvement/scientist attitude, and to try to maintain a good quality experience for other users. I'm not here to "have a good time" - if that's what you mean.

But I'm noticing a trend in decreasing submission and comment quality, and I don't know if other users realize that or if they are ignorant of it. HN is becoming more "average" everyday, and I feel that more and more readers are commenting with ignorance, unfounded assumptions, and generally bad arguments overall. In short, a lot of the comments are useless/inaccurate/invalid. I'm sure you notice it as well? How are we supposed to address this issue?

If it's frowned upon to post meta-comments (on HN or any forum or article), then I wish there was a service or feature (not restricted to HN) that allows people to submit/receive feedback and constructive criticism on their comments and diction.

You see many people using words such as "obviously", "only", "completely", but this category of words (degree/intensifier adverbs) is improper/inaccurate to use many times because of the unfounded/unsupported assumptions that they imply. It make me cringe every time I see that. It's an identifying feature of a bad comment, or one that could be better if more effective diction were used.

And improperly using those words puts a severe hole in the argument, but people still treat these types of comments the same way as valid ones when they shouldn't.
I found the third row hardest to sort. Is that the same for most people?
My point is not to argue- my parents are both from (different) Spanish-speaking countries, one born under an extreme right wing government, the other an extreme left wing government. One country improved while the other languishes near the bottom of all countries by any measure. The one that improved did so not by blaming others (even if others were to blame! and they were!) or by defending a clearly terrible government, which Venezuela clearly has.
Looking at the videos, a few milliseconds would correspond to ~1 drip, maybe 2. It isn't going to introduce a real significant flaw in anything.
My wager is that, especially for this initial release, that's being tossed into the sure-but-adds-complexity bin. Perhaps later versions will have a variable drip rate to speed up the process, but the complexity isn't needed in this version.
Well, before Facebook or MS or Google is doommed, I am sure BlackBerry is doomed first.
A lot of people are pretty explicit that they are looking to leverage the sharks specifically. The sharks are also pretty explicit, frequently saying "this is a good idea but not good enough for the amount of work I'd have to put in".

You can tell the ideas that the sharks think are good because they talk about how much of their time they're willing to give, not just the money.
Buffet is just a shill for the USG in the confidence game of US treasuries. Sure the fed is under no pressure to sell, the pressure is really on the fed to not stop buying.

QE infinity is all about hiding the fact foreigners are exiting treasuries so the fed is the last resort buyer of USG debt. Without the fed backstopping, interest rates paid by the USG on its debt would have to go up which would very quickly crash the system.

Warren is just doing his patriotic duty to kick the can a little further down the road.

Hmm, interesting to see Harris Corporation is on the list. They provide a lot of encryption gear to the U.S. government.
Paragraph 1: The Foreign Policy article decries "the Venezuelan economic model of excessive meddling". The Happiness Index report puts this in perspective.

Furthermore, the CEPR link points out: "It is perhaps not surprising that media outlets that regularly try to convince their audiences that the social democratic policies being pursued in countries in Scandinavia, South America and elsewhere are a failure don’t want to report the contentment of citizens living in these countries."

So, there is a propaganda aspect to such weird articles about... toilet paper. Particularly since Venezuela is such an enemy nation that Jimmy Carter publicly claims the US was "likely behind" the Venezuelan coup. (http://en.wikinews.org/wiki/Carter:_US_%22likely_behind%22_V...)

Paragraph 2 responded to a post which merely quoted Foreign Policy, a US magazine owned by a mass media company.

Your paragraph 3 is unclear to me.

Your paragraph 4 is ad hominem and ironic.
