In my experience, the best approach is to treat the notebook as the frontend. So widgets, graphs, annotations are generally ok. Anything compute intensive should be relegated to the backend.
In Savings and Loan crises of 80s, wall streets banks lost all the money they made during the previous 25 years. In the current crises, I dont know the exact number but it is worse than that.
So if you believe that wall street banks actually make any money, you might want to reconsider your view points.
So what happens when each node in the decision tree has probability attached to it. Worse still, what happens when you do not know the true probabilities of these nodes. Now imagine you have to deal problems all day with uncertain characteristics, i.e., decision trees have nodes with unknown probabilities. You will be stuck, unable to make decision.
This also reminds of the study in which a person's emotional part of the brain was removed (forgot name of the part, its the one that uses hueristics). So, he would have to make every decision completely rationally. That caused him to take a very long time to make even the simplest decisions, like which pencil to choose amongst a set pencils to write with.
This research seems to be suggesting that auditory-sequential (AS) learners are more intelligent, i.e., have higher IQ, than visual spatial (VS) learners.
If IQ is the measure of intelligence, then certainly, AS would be regarded as more intelligent. That is why AS learners do better at every single test that is timed or requires quickness of thought, be it SAT/GRE, mensa or job interviews at microsoft/google or a wall street bank or hedge fund.
Actually, the author is clearly stating the causal relationship. He is pointing out that free market fundamentalism is the cause of the crises and Business schools are the cheerleaders for free market fundamentalism.
Now, I personally do not agree with that argument, but your criticism of author's argument is unfounded.
I think this executive and all those who want to bury this guy are missing an important point.
In financial markets, you cannot judge performance simply by results, because it is very difficult to determine whether the good performance was due to any intelligent effort or simply due to good luck. Those guys making money off CDS were also being profitable for a long time. But now we know what they were doing was utterly shortsighted
So if this guy wants to prove that he deserves that bonus, he should show that he was doing something intelligent. If he knows this, than his letter is a deception. If he does not know this, he is not really that smart and does not deserve that bonus.
Ok, so certain mental abilities deteriorate. Maybe, some other mental abilities improve.
The problem with this research is that it is trying look at brain from a certain view point, ignoring all other view points. A more holistic approach would provide a better understanding of how mental abilities change over time.
To all those who share the personality traits of this "friend" of the blogger, how many of you believe your coding speed is slower than other hackers? From coding speed, I mean, say amount of time to finish a well defined programming project. Or to come up with an algorithm to solve a well defined problem and correctly implement it.
I obviously share many of these traits, and I know for a fact that I was slower than many of my peers in school, and later at work. I just had to spend more time doing the same amount of work. In the end though, I was able to produce similar results, albeit with more effort on my part.
Yes, thats true, some people might suck at everything. But that can be managed as long as thats a small enough minority. (we have government welfare for a reason, right? :))
The hypothesis I proposed is too broad to prove easily. Maybe, we can start with a narrower premise. We can disprove "if you suck in English class, you are no good for college". A friend of mine, a maths genius, got a D in History class in college (without deliberately trying to fail) He had straight A's in all technical courses (CS, maths etc).
I can bet that woman must be good at something she has never been tested on and probably does not know about. Maybe if we start from the premise that most individuals have something they are really good at, we might be able to move beyond the educational system of As and Fs and take advantage of people's abilities to the fullest.
