The reason people fall back to the I IV V and VI chords (C F G and Am in the key of C) is that going between them creates a false sense of forward motion in the listener without actually going anywhere. Moving from the IV to V creates tension that can be built up and released by resolving to the I, or increased by going to the VI and resolved to the IV. Any combination of those pretty much sounds "good". Variations add the II (Dm) in place of the V or in between the IV and V, or add the III on the way to the IV. It's really simple, and made even simpler by power chords because you don't even have to move your hand shape to play entire songs on rhythm. Leads can then switch between major scale phrases and pentatonic (aka blues) phrases of the minor of whatever key is being played in, (so Am blues over C) and almost anything they do sounds good to the average listener. In the end, you only have to keep their attention for ~40 seconds between hooks and just crutch on the catchy chorus and you've got a hit. But if you analyze most popular forms of music, the above is at their core anyway. It's just more bare bones in modern pop and rock music.

> But every time I tried hipmonk, the prices were higher than what I found elsewhere, so I stopped using it.

Same here, love the UX but when I first tried it a couple of years ago, prices were higher. I tried it again only a couple of weeks ago and prices were still much higher. It looks like hipmunk is an engineer driven company focused on technical stuff (great UX, no ads) but what's important here is getting the best deals with flights providers and they're still not there yet, even two years after the launch.

Yes, it is.

Your link is a video on Steam; a trailer for a movie available elsewhere. You can't actually buy Zombie Movie on Steam. Maybe you could, at some point? I haven't heard of it.

Indie Game: The Movie is the first movie available for purchase on Steam (as far as I know)! Steam has 40+ million users, so this is a pretty big precedent.
I hate myself. I can never answer questions like this, and I exhaust myself from trying so hard.

Throughout school, I was absolutely HOPELESS. I couldn't do anything when it came to basic math, except some algebra. These questions (even faced with the formula to solve it) still bugger my head. I tried to read books, get tutors, do everything to better myself (who ever heard of a computer guy who couldn't do math!).

I can easily write algorithms, do algebra, write complex programs, do anything on a computer but faced with a question like this my brain shuts down very quickly.

I stumbled across this one day... still not sure if I believe it's a thing... and that I have it: http://en.wikipedia.org/wiki/Dyscalculia
Right, all of the songs were normalized to C, which exactly the point. At Hooktheory.com you can examine all of the songs in relative notation (i.e. I IV V in place of C F G) which makes it easier to compare chord progressions without having to bother with their respective keys.
I'm on the same page. IQ is property of the genetic dice roll, not something that a person earns. Tangible results based measurements seem more appropriate. Pure intellect is the raw material & needs to be refined/applied to be useful.

edit: grammar
That is a fair critique of the article. The vast majority of the songs that came into the analysis were in fact billboard top 100 so that naturally filters out songs with chords that might sound bad (chords that as a rule are not built off of the major scale the song uses). What we found most interesting, however, was that there are certain patterns that really do show up. The one that was most striking, and that we pointed out in the article, is that the iii chord is almost always followed by IV or vi in pop music. There were similar trends for other some of the other chords that we'll be posting in a later article.
Obviously the tube would have to be incredibly strong, since it will have to withstand the water pressure at whatever depth it's at. I'd be curious to see calculations on that, as well as repair costs. Also costs for land-based vs sea-based.

Why Digital Talent Doesn't Want to Work at Your Company
The research is using SAT score as a proxy for general intelligence... I wonder if this sort of heuristic short-cutting actually correlates with test-taking ability more than it correlates with intellgence.

A lot of "test-taking" training basically consists of saving time by training away from full reasoning, in favor of cheap-and-good-enough heuristics. Furthermore, those heuristics are over-fitted to the particular problem types on standardized tests. I wonder how much of this study is actually measuring their ability to trigger test-taking instincts on problem types they're not designed for.
Hehe, yeh, I'm not intending to sound argumentative - just throwing out my contrary viewpoint to that of you and Patrick.

You've fairly hit the nail on the head, BTW, in noting the problems of transitioning. I'd love to have larger scale projects (if I could actually keep interested in them ;)) with "better" customers (for whatever value of better). One problem for an individual, though, is actually gaining work - I hated doing that. The thought of having to constantly pitch for work (and to a certain extent managing it) puts me off.

But on the other hand - these smaller customers are currently getting shitty snake oil work, so when they hear about developers doing solid work in a friendly way they will come and bite your hand off.

To some extent I view that a "good customer" as much as anything :)
I tend to feel much less angry about outages and such when the businesses take time to explained what happened, of course this doesn't justify the lack of up-time but I like the gesture!
Pretty sure the title is alarmist and inacurrate.

The paper itself notes an increase consumption of fat and decreased consumption of carbohydrates. That is not the same as a low carb diet. For example (from the paper):

> Fats used for spreading on bread and cooking, dairy products, oil for salad dressing or cooking, various types of meats and sausages as main dish or on sandwiches, pizza, deep- fried potato chips (French fries), and non-sweet snacks (including potato and maize crisps (chips), cheese-flavoured puffed products, popcorn, and peanuts) were identified to be associated with high fat intake (fatE%) in the study population by PLS.

Few of these foods are recommended in low carb diets. Nor do the percentages of calories from carbs given in the study come anywhere near those recommended by low carb diets.

Zombie Movie is fully available through Steam (it's a short that some Valve employees made). Your point stands, though; It's the first instance of a movie available for purchase through Steam, the games I bought for the cutscenes nonwithstanding.
I used the online chat support for an Asus laptop whose monitor went out after a few months. I kept asking if this was a human or a machine because it felt incredibly automated.

Hi planetguy, that is an excellent suggestion, and something we've actually already started working on. One of the things about the database our community is building is that it can be used for so many interesting studies. BTW, the Rihanna song you mentioned came on the other day and I heard someone sing "we found Dove in a soapless place". Couldn't help but laugh.
>and was literally blown away

Where did you end up? Did you land on something soft?
I think it's simpler than that:

(1) People learn to play guitar by playing popular songs. These popular songs feature a subset of chords in certain combinations that sound good (eg. C->G->Am->F, C->Am-F-G, Am->F->C->G).

(2) People start creating their own songs using the mental maps of "what chords sound good together" from step #1.

(3) Rinse, repeat

My feeling is that it helps that these patterns are easier to play in C, but I think it's really about matching the "what chord comes next" pattern to a particular key.
Dear The Internet, This Is Why You Can't Have Anything Nice
Cool, once you gain traction, I would definitely explore partnering with an OEM to get your application preloaded and work out some kind of deal that way. I think it would be a hit.
I think you are misunderstanding the article - All the songs were transposed to the key of C for the purpose of analyzing chords, so don't draw conclusions from the actual chord names presented as the most populat. Instead, what the article is saying is that the I, IV, V chords are the three most common (as one would expect from basic music theory). In the key of C, these are C, F, and G, so that is how it is presented.

Good luck holding a vacuum under the ocean. I read stuff like this and I think, "Gee, I don't think these people have actually built anything." because if they had they would realize that if it costs $1M a foot too build subways [1] in cities with moderately skilled labor, its going to cost $10 - 25M/ft to build something like this. That's half a quadrillion dollars (448 trillion dollars). What sort or rate of return do you think you would need to make that feasible?

I'd love someone to actually do a credible cost analysis of an evacuated tunnel train. Unfortunately I don't think Oster did.

The original paper (http://arxiv.org/abs/1109.4897) had some 188 authors. I doubt they didn't double-check or 100-check the results. After some point the data just had to be considered believable or worthy of publication. You really think it would be better if they didn't let the world know about it?
Safe to say that the terrorists have won, if the first eight comments on something as cool as this have to do with possible ways the terrorists can destroy it. What a depressing new era.
Hey Jimmy,

Hooktheory stores all of its chord progressions in relative notation so we have tools to answer questions like the one you've posted here. Although the Hooktheory database is relatively small, we have 20 songs that contain I vi IV V, compared with 100 songs containing I V vi IV. Just by visual inspection, of the songs that contain I V vi IV, none of them were written before 1975, which may not prove, but certainly supports your claim.
> Also, easy terrorist target.

What a shame this determination is made on so many "advancements" now.

Not trying to knock your article - just wanted to clarify the title, that it's more of a personal "things I learned" than an intro for beginners.

I agree that the Ember docs are pretty weak and missing some key pieces that one might miss when starting out.
"How do you make multiple cursors that are at the exact locations you need?"

There are a few simple tricks.

In this case, I hit "ctrl-d", which does the following:

1. If nothing is selected, it will select the word the cursor is on.

2. If something is selected, it will select the next match of this word, using another cursor.

In other words, I'll put my cursor on "def", hit ctrl-d, and "def" will be selected. Hit ctrl-d again, and the next "def" will be selected. Etc. Technically, in Sublime Text, every search makes a multiple cursor. I could hit alt-f3 (IIRC) to select all matches of "def", and they'd all be multi-selected.

But like I said, in this case it's really easy.

There are more advanced tricks - what if the word "def" appears inside the text? Well, you can select not only the def, but also the whitespace before the def, and it will selected the next "def" which is at that exact indentation. And like I mentioned in another comment, I even wrote a plugin to make multi-selections more easily, by splitting on a certain character. So that a list like this: (int a, int b, char c) can easily be split into 3 selections, around the comma.
Kudos to them for promoting women in engineering. What I don't understand why calling it a gambit?

I've worked for a startup for two years, btw.
That would be a blessing.
Here's how I broke it down.. (which is apparently wrong)

A bat and ball cost a dollar and ten cents.

Bat + Bal = 1.10

The bat costs a dollar more than the ball.

Bat = Bal + 1.00

How much does the ball cost?

Bal = ??

So..

Bat + Bal = 1.10
Bat = Bal + 1.00

Therefore

1.00 + Bal = 1.10
Bal = .10
1.00 + .10 = 1.10

This seems logical..

Aside: fuck that script that messes with your copypaste, and the same sentiment to sites that implement it

Cheers!
The chord choices in Garageband are the chords found within the scale of C, plus Bb (even the Bdim - but, to be pedant, it should actually be a B7b5). Having Bb you can modulate (or "change the key") to F without having to switch scales etc.

Also, the fact that he found D, E and A among the results is probably because of modulations. It's VERY common for pop songs to modulate a whole step during some chorus near the end [1]. As mentioned, G, F and C are V, IV and I. If we modulate a whole step, from C to D, the V, IV and I are A, G and D. It would be nice to consider those modulations into the research.

About the key choice, I believe it's irrelevant. It depends a lot on what's your instrument (Bb, Eb is easier on brass instruments), your style (lots of Metal songs in the key of E because E is the lowest note on guitar), your tuning (lots of rock bands downtune their guitars to Eb or D etc), your proficiency, and, most important, the vocalists range.

Kahneman divides our thinking into two subsystems: type 1 and type 2. Type 1 thinking is fast, intuitive, unconscious thought. Most everyday activities (like driving, talking, cleaning, etc.) make heavy use of the type 1 system. The type 2 system is slow, calculating, conscious thought. When you're doing a difficult math problem or thinking carefully about a philosophical problem, you're engaging the type 2 system. From Kahneman's perspective, the big difference between type 1 and type 2 thinking is that type 1 is fast and easy but very susceptible to bias, whereas type 2 is slow and requires conscious effort but is much more resistant to cognitive biases.

Traditionally, "intelligence" (as colloquially defined) has correlated with type 2 thinking. So, a reasonable conjecture would be that people who are better at type 2 thinking would use it more and, therefore be less vulnerable to bias. However, this research shows that even those who are very good at type 2 thinking (as measured by their SAT scores and NCS scores) are even more vulnerable to cognitive biases. This is a deeply counter-intuitive result. Why is it that people who have a greater capacity to overcome bias have a greater vulnerability to bias?
> Credit card companies have a lot more leverage than individuals to lean on companies to respect their own return policies.

Not just leverage, but an obligation. Or rather, even if your debit card says Visa or Mastercard on it, they have no legal obligation to get your money back. You don't have an obligation to pay the merchant, but the impetus is on you to get your rightful money back (the debit card company may help, but they are not required to).

With a credit card, they don't exactly have an obligation either, but this time it works in your favor - it's the credit card's money, not yours, and while you still have no obligation to pay the merchant, this time it's the company's money that is on the line (the collateral, so to speak). So they will fight tooth-and-nail to get it back, because technically if they don't, they can't collect any money from you.

(They may still try, but then you have to weigh the cost of a legal battle with them as well).

Think of this in the context of theft/fraudulent use of your card, and you'll see why debit cards are very risky indeed. (Remember that, even if you manage to get chargebacks on your debit card, you may still be liable for the fees for the temporary, eventually-reversed overdrafts!)
Cloud Deployment of Hadoop and HBase (Part 1-2)
Well, airplanes are a considerable distance up in the sky and incredibly difficult to reach. It's why the vast majority of plane-related "badness" happens shortly after takeoff or shortly before landing. Any land-based rail vacuum tunnel would not be protected in this way. An underwater one would be to an extent- I suppose it depends how deep it goes. But it's still a lot easier to drop something (say, a bomb) into water and let it sink than it is to fire it into the air and hit a plane.

Haha! No chance. We might not even see the new link between London and Birmingham (HS2) before 2035, never mind one to New York!
The linked blog post is a bit of a rant. Sounds like the author really hates hipsters and just wishes to accuse them of being racist without actually providing any substantial evidence to back the claim. If "hipster racism" is a legitimate phenomenon, I'd like to read about it from another source.

On the main point, the Swedish troll isn't really saying anything overtly racist. She is just mentioning a number of things that make people feel uncomfortable and making some questionable remarks that are obviously designed to be incendiary. I'm not sure this fits into the "hipster racism" model, as described in the linked blog.

> I think the benefits are thus provided by VISA/etc, regardless of what services your bank provides through the card, like credit.

See my above reply - they may provide similar services as if as a "courtesy", but the legal obligations for both parties are very different with credit and debit cards (very much in the consumer's favor, if the consumer is using a credit card).
Of course you're right about basic/smartphone difference. I'm not sure how I overlooked that. It'd be nice to see a lower base rate but they've convinced the average consumer to be happy to get a "free" phone every two years.

It's actually $10/mo more for non-tablets, which results in the absurd situation where you're paying $10/mo more for the right to use a device where you'll likely need to pay more, again, for data. Of course, the average consumer won't notice this absurdity, which I believe is the basis for all of their pricing logic.
It is ridiculous to suppose that one's score on a multiple choice test is an accurate measure of innate ability or real-world intelligence.

The SAT, ACT, IQ tests, and all standardized test like them are socially constructed concepts that ATTEMPT a method of measuring intelligence. Intelligence (in the real world) reaches far beyond one's abilities to answer multiple choice reading comprehension, basic math and writing. Not to mention that problem solving in the real world has no time constraints.

Beethoven would not have gotten a perfect score on his SAT's. However, we all can attest to his innovation, creativity and musical genius. How can a multiple choice test measure the creative abilities of people like Sir Richard Branson, Steve Jobs, or Pablo Picasso?

The idea that "smarter people... were slightly more vulnerable to common mental mistakes" is a nonsensical conclusion. These findings are completely worthless.

I think she did awesome, even I fell for it.

First she says that jews are just like other people. Woah! That's some weird thinking!

She photoshops Freddy Mercury (who was gay and had aids) into a picture with food calling it "hungry gay with aids" which you might call vulgar maybe (just as the urine picture caption) but how is it wrong?

She keeps doing a few more bad jokes.

I think if she wanted to troll she did a really great job! People are up in arms about a few harmless comments and pictures, I definitely do applaud her:)
I think this is more an issue of the English language. English is not a good way to speak math or logic. In the bat and ball question I mistakenly (and I'm guessing everyone who got it wrong) ignored the word "more". That word represents an operator and is therefore crucial to the question, but is extremely diminutive in terms of English language.
How else would you describe them?
