This doesn't surprise me one bit. I think we all have sensitivities to various unnatural concentrations that we "politely overlook." Food and chemicals are the most obvious ones. Most paper gets treated, but it could also be intrinsic to paper being a fibrous, naturally decomposing product. I will have to let my parents know about this one, since they have zillions of books and my dad has persistent asthma.

Personally, I've been food-focused and have discovered that the occasional mild, but painful swelling I had was caused by the excessively high amounts of EFAs found in vegetable oils(the naturally occuring amount is tiny); simultaneously, most of my tired/inactive/sick feelings were the result of eating grains and beans. It took a very long time to sort through bullshit nutrition info and figure out the exact triggers, but minimizing intake of those three has been a tremendous lifestyle improvement.
> because it's quite rude to be so condescending.

So? I'm occasionally rude.

The changes in journalism are distribution and a perception of who is pulling the strings. However, strings were always being pulled.

And, the perception of who is pulling the strings hasn't actually changed. Folks have been complaining about big biz, "outside agents", etc for as long as news has existed. They wouldn't have called it "big rail", but ....

A lot of people talk of splintering as if it doesn't exist on the iPhone.

1. different devices have different hardware capabilities: my 1G doesn't have bluetooth, early iPods don't have a camera, etc. Apps have to deal with that on every platform and it'll only get worse as Apple ads more hardware features.

2. different screen resolutions: Android is simply ahead of the game on this one, the iPhone isn't going to stay at 480x320 forever (I'm willing to bet a lot of money next year's iteration will not have that resolution)
Ask HN: The Primers on different subjects
While studying Computer Science I've collected a set of different primer CS books. SICP is however considered to be the book among CS students (I agree with that). But as a curious guy who enjoy to be stimulated intellectually - I would love to know the primers/classics in the following subjects:

- Architecture
- Philosophy
- Psychology
- Medicine
- Physics
Well, presumably this phenomenon has been tested in the hands of professionals who play violins every day. A pro will own several instruments, for example, many of which will be in storage.

Having said that, your point is very real. I find it hard to believe that it's easy to conduct a double-blind test of violins. Violinists are not robots. Put two different violins into their hands and they will notice a difference, and their playing will change. Can you really set up two violins to the point where even a blindfolded violinist, feeling them under the fingers, can't tell when you swap one instrument for another? Same size and shape? Same string tension? Same feel of the finish on the neck? Same bridge placement? Same tension on the tuning pegs?

As you point out, even the sound of a piano is acutely sensitive to subtle differences in playing style, and a piano's sound is much more constrained by its design than the sound of a violin.
If you don't mind sharing, which of the three designers mentioned did you hire and why?
Group by continent.

Organizing a flat list of 50 items into 7 groups of 7[1] should improve accessibility, if the categories make any sort of sense. I would be interested in seeing research comparisons of flat dropdown vs grouped dropdown (ie some items are unindented unselectable categories) vs double-dropdown, where the items available in the second are determined by the selection of the first.

[1] For the purposes of dropdown menu length, 49 is equal to 50.
It would cost around $8-12k for a decent sized website. Our website is pretty small and had the benefit of carrying over a lot of assets from the application itself so 3-4k? I am actually working on evolving the site because I am not happy with where it is right now.

Of course design needs time to bake in the oven. You can't grind out a website every two weeks. I normally design a page and then forget about it for at least a day so I can get a fresh look at it. Sometimes you stumble upon the right design the first time, sometimes you need to go through dozens of ideas. It's all very unpredictable.

For the application itself that is a different story. It is a tremendous amount of work designing a app from the ground up so we are talking 80-100k at least. (I did all the HTML + CSS as well) Took me about a year worth of weekends to get it where it is right now. Being a co-founder I also got to make a lot of decisions without any input so it makes things move a lot faster.
Yes, I did work on that. I used a neural network to trade FX. I wrote my own neutral network framework using code generators for x86 and CUDA.

The neural network was a fairly normal feed-forward network with GA-inspired, but heavily modified learning process. It combined layers of neurons with memory and memory-less neurons. It is essential to keep the network size small, because a big network will just memorize the data you use to train it.

Also, I used several other inputs, such as the frequency of trades per minute, overnight rates for each currency, and stock market indexes for the relevant countries.

Finding historic data was the biggest problem. I used Bloomberg data from my university, but that was a pain in so many ways. There is NO free data for most of the inputs I needed. Good data from Thomson Reuters or something like starts at $5k/mo.

Overall, the model worked fairly well, generating about 10% annual returns even with a few handicaps I put to be on the safe side. This was about an year ago and the only reason I stopped working on it was that my partner in the financial startup quit. I'm sorry if some of my terminology is wrong - I haven't been working in that field since then. If you have any questions, I'd be happy to talk about this. My email is in my profile.

> Regulation is a rule (or law). Fannie Mae and Freddie Mac are government sponsored enterprises (GSEs).

Fannie and Freddie are creations of law in the form of GSEs. Their GSE status made them especially vulnerable to govt interference. They weren't independent of govt in any meaningful sense.

> That would be like saying the Small Business Administration is business regulation.

It would be if SBA controlled as large a segment of biz lending as Fannie and Freddie did of the mortgage market.

Fannie and Freddie define "conforming mortgage". Their lending standards define what mortages are sellable.

If they screw it up, as they did, the market takes a huge hit.

> Also, to my knowledge Fannie and Freddie did not fail.

They got billions of dollars pumped into them and their stock price collapsed. They're not essentially in receivership and are running on govt funds. That's failure.

> I think we would have noticed considering they cover trillions of dollars worth of mortgages.

What's to notice?

The failure of an institution doesn't imply that the debts owed it go away, so folks are still paying their mortgages (or not), regardless of Fannie and Freddie's problems.

The take-over is designed to keep mortgages flowing. For a while it wasn't working - if you were looking for a mortgage, you noticed.
That article seems a tad bit unscientific. Just because more books can be ordered online than any physical bookstore could stock, it doesn't follow that more books are successful (they may or may not be - I miss the data proving the point).

One thing is certain, though: Amazon sucks as a recommendation engine. Basically they also just push the bestsellers onto the public. It is very difficult to browse and discover on Amazon. (Not counting "You may also like" - will they really derive some exotic novels from someone reading the latest Dan Brown?).

As we now (from actual scientific experiments), what becomes a bestseller in a channel could be random to a big part. So the fewer the channels, the fewer the bestsellers could be a possible conclusion.

On the other hand, maybe that bodes well for the small book stores - so far they still have no competition on the web for individualized recommendations, or personality (many small bookstores reflect the tastes of their owners).

No idea on the experience (never been in a bar, and college was a long time ago). Judging by outside appearances of the ones I've seen, I'd say that your dive bar + 70s laundromat isn't far off.
To be fair, it also takes a lot of energy to cut down a tree, ship it to a paper mill, boil and smash it to pulp, mold that into paper, ship the paper to a printer, ship the printed book to you...

I don't really know which will win in energy-efficiency terms. Probably depends on the lifetime of an ebook reader before it breaks or -- far more likely -- becomes obsolete and needs to be either thrown away or kept in the back of my closet until I can bring myself to throw it away. I really wish I knew how long that was.

I'll trust (professional) practitioners over theorists most any day. I used to be a pro photojournalist and I remember "arguing" with someone over "the best camera". It was me, who has owned and used most of the best cameras and lens' available and who field tested some of the first serious pro digital bodies against a photo enthusiast who had read Consumer Reports and a variety of other reviews and had a fair amount of experience with shooting snapshots. It was ridiculous as he, a non-practitioner from a pro point of view, simply did not understand what really mattered at the highest level of use.

Requiring GPL on derivative works is the one-way boundary I mentioned; the simulated "copyright-free zone" in question is comprised of all GPL-licensed software, so anything existing wholly within that realm isn't impacted. The purpose of the derivative license requirement is to discourage external dependencies creating copyright-by-proxy inside the GPL zone.

I don't actually think the source code publishing requirement is necessary; something like CC BY-SA would probably suffice.
Because it is possible with a Turing machine.

The idea (iirc, and poorly translated into more familiar vocabulary) is that when we're running a quantum Turing machine on a regular machine, the data on the tape can be "quantum encoded". There is a specific series of steps for "decoding" it, but it's a destructive operation: decoding the data screws up the data. Decoding it a second time gives you broken data, and you know that it's broken.

(You might wonder, why don't we just write a Turing machine that can decode the data without destroying it? Well, you're free to do so, but then it's no longer a quantum Turing machine running on a Turing machine - it's no longer the same as the physics, can't be implemented directly in quantum physics, and therefore would be both slow and potentially have a tape with more slots than atoms in our universe.)
>> "You need to be available 24/7"

And that's where you make the mistake. Look at twitter. Look at facebook. Look at anything else. They're all broken from time to time, all offline every so often. People are pretty forgiving especially at the start.

> Can't you just download a historical set and use that to test whatever algorithms you think you would use?

Be careful - much of the historical data has been pruned to eliminate some data from companies that didn't survive.

I've heard that one of the major quant houses (Shaw?) can often guess what data set you used to test your strategy by looking at the strategy.

Plus, there's a selection or fitting problem. Your strategy may have worked well on average from 1972-1999, but that doesn't mean that it will work today.

And there's a velocity problem. There are pricing errors in old data to exploit. And, if you had today's computers then, you might have been able to find them fast enough because your systems are faster than what folks had then. However, today you're competing with folks who have faster systems than you do.
You sound like a programmer that is "difficult."

It also sounds like you're the type of programmer that doesn't treat designers with any respect, so they likely reciprocate -- the type that doesn't like to collaborate, but just boss people around (it's more than apparent from your post that you sneeringly look down upon the design profession). In short, you come across like a huge jerk and I can't imagine what it must be like to work with you.

Let me see, according to you, designers that are "great to work with" (the ones that just shut-up and do whatever you tell them) produce "eye pollution". The ones that are "difficult" (have opinions and give input whether you want to hear it or not) end up producing "incredible work", but you just hate working with them.

Ever consider that the problem might be you?

"Selling live shows, selling merchendise, selling music in a form that makes it a "collectable", even music for films etc..."

Many of which are not really making music, though. What if you simply want to make music? You might as well say "musicians can get paid for doing TV commercials for facial creams" - maybe they can, but I doubt it is what they had in mind when they went into music.

In fact, if I was looking for a cleaning lady, and Bjork as well as some unknown woman would apply, I would probably prefer Bjork. So in that sense "musicians can make money by becoming room cleaners".

I've not looked into Go yet (I go on holiday and Google release a new language while I'm a away, hmph!) but if it's anything like Objective-C's 'protocols', it could work. You'd need to capture any messages and forward them to the appropriate component using some fast dispatching mechanism (hash table, I guess).
A nice value add over what you can already do by just posting a Facebook status update / shooting out a message on Twitter would be to do a time-delayed push of the message. If I know I want to go shoot pool tomorrow night, put that on your site, shoot it out over Facebook/Twitter/whatever with a link back to your site, then if I haven't created plans, push out a 'last chance' status update that is closer to the time when I want to go do whatever it is I wanted to do.

More generically, I can see value in choosing a strategy to publish information at some future time and not having to do it manually.
I haven't been to siggraph, but for $1,175 ( http://www.siggraph.org/s2010/for_attendees/registration ) there's surely a potential for a contract between you and the ACM via your conference registration.

Also, copyright holders don't need to enter into a contract to assert their rights. You don't enter into a contract when you watch TV but you still don't get the right copy and distribute shows (or sporting events) that you watch.
So, when the table moves under the microphone because of the vibration the microphone will try to resist the movement because of inertia, the force will show up as a reading of a voltage on the scope.

If I wanted to use this to document the noise in court, this still wouldn't help me. Even if I did a "baseline" for comparison, how do I bridge the gap between the readings on the scope and the concept of "annoying noise" to the judge? There are ways, but the more stuff I have to do, the more it seems like contrivance to the layperson.

Of course, I don't really want to take this to court, but this illustrates my problem in any legal context.

It also illustrates the problem of dealing empirically with direct experience at the fringes of perception.

they already have those mobile keyboards which are projected onto a flat surface and then use sensors to detect what keys your fingers are pressing right? So why not just have that as the input, the actual device size could be arbitrarily small and still allow you to have a full size keyboard whenever needed...

real development is a long process that requires concentration and endurance, not some quick 1 hour hack, i highly doubt programmers are going to fundamentally change the way they code just so they can do it on their iphone while theyre on the train or at a bar.

as for the screen, im sure eventually we'll have either something similar to the keyboard ( a high quality projected screen ), or some e-paper type screen which when unfolded is full size but folds up into the device.
Perhaps it's worth considering chorded keyboards? They're smaller than regular keyboards, and the rate of input is much faster. For a certain segment of the population the tradeoff could be worth it, but you can't find them in the right form factor -- for now.
> You've just made an excellent argument for why universal coverage (of some sort, public or private) is essential.

Not at all. The factory model produces significant savings in processes without anything like universal coverage.

For example, the factory model produces those benefits for for IC manufacture, automobiles, clothing, printing, agriculture, etc.

hey, nice idea - but that's not how it works.

there's no intrusion detection - an attacker increases the error rate, and by the error rate we can calculate the maximum probabilistic information an attacker plausibly might have. i say can, because that number is actually pretty uninteresting, since it isn't intrusion detection - we just now there's something causing the error rate to go up - doesn't have to be an attacker. a higher error rate in practice just means we gotta throw more bits away both during error correction and during privacy amplification - which is kinda like packetloss on a classical channel.

at some point the error rate is too high for error correction with a positive yield (= more key lost in communication, than gained through said communication) - thus the scheme stops working.

my personal favorite name is 'quantum key growing', because that's essentially what happens - you turn an initial shared secret (= random key) into a longer random key. (and while you're continually doing this, you're using up part of the previous key to secure communication as you go along)

I've been friends with Antonio for years, and can attest to the quality and professionalism he puts into his work.
I have a Nokia n800 (previous model was the n770, follow on is n810, now n900) with an iGo bluetooth keyboard (folding - great for portability, not great for typing). The display is 800x480 so it is vertically challenged, but usable (with good bifocals ;-).

I've used it with ssh into a remote machine and also at meetings to take notes on. If I were doing extensive typing, I would get a compact non-folding BT keyboard - I hear the Apple one is pretty good for size and touch-typing.

The n800/n810/n900 has enough horsepower to do light weight lifting, including a SD/microSD slot that give "unlimited" storage space. The n810 and n900 have built in keyboards (not a replacement for a BT keyboard) and the n900 does "TV out".

- http://maemo.nokia.com/n900/

- http://usa.nokia.com/find-products/phones/nokia-n810/specifi...

The problems are obvious...

- The screen is tiny

- Keyboards that you can touch-type on are big

By the time you bundle in a keyboard, the recharger, various wires, etc., you might as well lug around a netbook. On the other hand, I carry my n800 everywhere in my pocket - it may be difficult to do something on the n800, but it still beats a netbook that was left at home.

I also have an Acer Aspire One that is touch-typeable and has a larger display at 1024x600 (still cramped) and an OLPC - display is interesting but the keyboard is not touch typeable, the CPU is pretty slow, and the battery life isn't very good :-(.
My first impression is that the author is on treacherous philosophical ground. He seems distrustful of "group morality" (incidentally, I would argue that morality is inherently a function of groups) yet claims more sociopaths is a "good" thing. But in what sense does he mean "good"? As defined by the group morality he finds questionable elsewhere?

I'm unfamiliar with the author, but one possible way of resolving the apparent contradiction would be to distinguish between "good vs. evil" and "good vs. bad" - a solution originally, as far as I know, proposed by Nietzsche, where "good vs. evil" is a matter of group, "slave" morality, while "good vs. bad" is a matter of "master" morality. It actually maps quite cleanly to what the author is talking about, though I'm uncertain whether or not that is deliberate.

Edit: Also, statements like

(you're either slavish and unthinking, or a sociopath)

feel a bit like misreading the author to me; he's abusing the word "sociopath", which can be criticized, but here you appear to be using it in a non-value-neutral manner, which rather misses the point of the article.

I preferred the third one because their website was more usable -- all work was on one page and all I had to do was scroll down. Unlike the others where I had to click specific projects then view pictures 1, 2, 3, 4... real turn-off when I'm trying to easily compare all three together.

The third also looks like there has been a real effort and focus on usable websites without a disregard for looks which is essentially what I would be looking for.
"natural monopoly" is economist's jargon. It is basic jargon. Every undergraduate economics text book covers it. Mankiw's Principles of Economics discusses it on page 306. Economics by Parkin and King cover it on page 296. Beardshaw sees to have something against the term, talking instead about "The flat bottomed average cost curve" on page 266. Alchian and Allen discuss natural monopoly on page 290 of Exchange and Production. Google it.
