ckuehne··on Why I'd never work for Google, Twitter, or Facebook
Why exactly is this harmful, i.e., who is harmed and by how much?
ckuehne··on Why I'd never work for Google, Twitter, or Facebook
Except that they do. Ever wondered, for example, how Google, Apple, Microsoft or any other public company that makes products you are likely using got their main funding? (Hint: IPO.)
ckuehne··on "We Really Don't Know How To Compute" - Sussman keynote at Strange Loop
I agree with quite a bit of your argument. However, what exactly do you think do "computers build from gates" depend on if not the laws of physics?

ckuehne··on Bjorn Lomborg: Our lifestyle is unsustainable and why that's irrelevant
"I challenge you to come up with a proper definition, if you think the 'free market' will save us"

I will do no such thing because I have not argued that "a free market will save us". I solely wanted to note that arguing over definitions and making caricatures of commonly understood terms ("But what does it really mean to be free?") is pointless and does not add much to the discussion at hand.

I agree, however, with the comment made by gaius: historically it is more probable that a free market produces innovation than a centrally planned economy. Not, IMHO, because the abstract entity “free market” somehow magically comes up with a solution. But rather because it allows individuals to tinker and to test their results w.r.t. the actual wants and needs of other people as opposed to assuming that the best solution can be planned and designed top down.

Most categories break down if you stretch them far enough. That does not mean that they are not useful. Fare from it. Usually, there is some common understanding what words mean. For example, if I say “forest” most people will know what I mean, without arguing that there are no real forests only single trees [1]. Just as most people will agree, that markets in the western world are free (or more free) when compared to markets in Soviet Russia (the term “black market” should have tipped you off).

[1] In the same manner one could argue that fossil oils really are renewable resources if the time frame under consideration is chosen to be long enough.

"Even in communist Russia there was a free market. It was just that the cost [...] was incredibly high (like death penalty)."

According to your definition prisoners are also free. It's just the cost of breaking out of prison are incredibly high (like death penalty).

ckuehne··on Coding tricks I learnt at Apple
So what you are saying is that the whole database research community does not really know what a B-Tree is [1]?

[1] Every database implementation techniques lecture compares the two. See, e.g., http://infolab.stanford.edu/~hyunjung/cs346/.

ckuehne··on The brain's 5-million core, 9 Hz computer
You quoted a statement Leibniz made about 300 years before Turing proved that there are machines that can compute everything that is computable. I and others explained in comments below, why we have reason to believe, that computers are fundamentally different from mills and that Leibniz's argument as well as Searle's fall flat. By the way, it is not the necessarily the "complexity of a computer that may create a more attractive analogy". The physical parts of computers can be less complex than those of mills. I wonder how Leibniz would have reacted if he had been shown Google. Would he have believed, for example, that the essence for its face recognition software must be "sought in simple substance"?

For more rebuttals of the Chinese Room argument see its Wikipedia page. I like this one in particular: A guy sits in a room and waves a magnet up and down therefore creating electromagnetic waves. But you don't see light coming out. So light cannot possibly be electromagnetic waves.

>>There is a crucial difference between believing that a computer can simulate a brain and believing that a windmill can do so. >That depends entirely on what you think a brain is

No. It depends on what you think a computer is. You see, the reason why many scientist today believe that a brain is computer or can be simulated by a computer is that computers are universal machines. In contrast to a mill, which can only mill grains, a computer can simulate earthquakes, the weather, cars, other computers, and, you guessed it, mills.

>People are ignoring a good lot of scientific method when they propose that were a computer to every simulate a brain the veracity of that simulation could ever be verified.

You seem to ignore the http://en.wikipedia.org/wiki/Turing_test.

>What would essentially be needed in the simulation, that is the production of consciousness, could never empirically tested.

How do you know that I am conscious? Or any other person you converse with for that matter.

ckuehne··on The brain's 5-million core, 9 Hz computer
Whenever I see Searle's Chinese Room argument, or a version of it, invoked to show that brains cannot possibly be computers I am reminded of a passage of Terry Bison's "They're Made out of Meat" [1]:

"They're made out of meat."

"Meat?"

"Meat. They're made out of meat."

"Meat?"

"There's no doubt about it. We picked up several from different parts of the planet, took them aboard our recon vessels, and probed them all the way through. They're completely meat."

"That's impossible. What about the radio signals? The messages to the stars?"

"They use the radio waves to talk, but the signals don't come from them. The signals come from machines."

"So who made the machines? That's who we want to contact."

"They made the machines. That's what I'm trying to tell you. Meat made the machines."

"That's ridiculous. How can meat make a machine? You're asking me to believe in sentient meat."

ckuehne··on The brain's 5-million core, 9 Hz computer
Your reasoning is wrong. There is a crucial difference between believing that a computer can simulate a brain and believing that a windmill can do so. That is, that a computer can, in principle, simulate mills as well as city-states and all the other objects you listed.

"It would be the most surprising thing of all were we to find out that evolution produced a kind of technology before in fact that technology as a human tool was ever produced"

Evolution has produced technologies long before humans invented them. For example, bats and whales use sonar, humans use lenses, plants use photosynthesis. In fact, one could argue evolution does not much else than to invent technologies.

Or "Zeitgeist" and "Schadenfreude" for that matter.

Not to forget, making money from it, or, at least, bringing money to the associated laboratories or doctors.

ckuehne··on "Steep Learning Curve" is an Erroneous Metaphor
"The concept of a 'steep curve' is the physical analogy to a steep hill"

Of course it is. That is likely the reason why the meaning got mixed up in the first place. The rest of your comment is rationalization (Otherwise, people would call it cumulative effort curve.). See richardw's sister comment.

ckuehne··on "Steep Learning Curve" is an Erroneous Metaphor
Thanks. I had seen the Wikipedia entry (but not the stackexchange and the Seth Roberts post) as well but did not post it because I found it interesting to see everyone come up with rationalizations for why their usage of the phrase is 'the correct one'. :)
ckuehne··on "Steep Learning Curve" is an Erroneous Metaphor
"I feel like the graph is a poor choice in illustrating this idea. As it's central to the argument, the rest of the article falls apart, in my eyes."

What, in your eyes, does the word "curve" refer to then?

ckuehne··on The blue-eyed islanders puzzle
Thanks. That was very helpful. Its easy to see but somehow hard to believe that this applies to 4 people as well (now everyone can see 3 blue eyed people) etc.
ckuehne··on The blue-eyed islanders puzzle
The case with 3 people always bugs me in solutions for this puzzle: If Alice, Bob, and Carol have blue eyes how can they not know that everyone knows that there are blue eyed people?

Of course the question arises: who will overturn the "overturner"?
ckuehne··on We should stop running away from radiation
It was a great tragedy. But neither was the the number of deformed children nor the number of cases of cancer "countless". There have been put numbers on it [1].

ckuehne··on Rising Wealth Inequality: Should We Care?
"The author confuses linear distributions with exponential ones, comparing them as stacked bar graphs without suitable differentiation of axis."

Could you elaborate? By the way, the graph is taken from the original paper (click the details link below the graph).

ckuehne··on Why aren't more women airline pilots?
No prior experience required. Just German Abitur [1].

ckuehne··on Why aren't more women airline pilots?
I don't think money is the problem here. In Germany, Lufthansa, the largest airline and has the following model: the pilot program takes 24 months. Students have to pay 60k Euro which the get pre-financed by Lufthansa interest free. The have to pay it back once they get a job at Lufthansa (entry salary 60k/year). If they don't get a Lufthansa job within 5 years they don't have to pay it back. So basically, there is very little financial risk and the job is very well paid. They even give a job guarantee after pregnancy.

Still the female pilot ratio is less than 5 percent.
