In maths, the people who write the proof sometimes aren't the people who make it rigorous. The elements of the proof are there and there are people who like coming in and fixing it. Same thing with grammar/writing...There are people who like coming in and fixing it.

Thanks, a combination of lack sleep and food the last couple days. See the last line, I knew there were tons of mistakes but up in the sky so hard to see them.

It means attack the problem from a point of interest. Ergo, can mean reading that same book ;), back to front maybe :D

It's not the universities that are racial bias because Asians are overrepresented at Ivy League school.

The real question should be why is the SAT so racially bias?

Personally, I'm waiting for you guys to go again. From, HNLondon meetups, to busmapper to donothingfor2minutes, to the turntable hack, I haven't meet anyone with so much executing power. Having that many successes in such a short time is not luck.

[PS. If you do set sail again, give me a shout. Shipmate Chester Grant reporting for duty.]

chegra84··on I want to fix programming
“Computer generate for me the sequence of all possible steps I could take; highlight moves that results in high economic and emotional payoff. Feel free to use alpha beta pruning and dynamic programming to reduce the time taken to polynomial time. Also, constrain possible moves to reflect my personal proclivities. Also, highlight a path were I'm dating Alicia Keys and Drake is with Nicki Minaj.. hate to see him beg on a music video.” [1]

My dream programming language should be able to run this. Good luck.

"In the mosaic of America, three groups that have been unusually successful are Asian-Americans, Jews and West Indian blacks — and in that there may be some lessons for the rest of us."

http://www.nytimes.com/2009/06/07/opinion/07kristof.html?_r=...

"Do African immigrants make the smartest Americans? The question may sound outlandish, but if you were judging by statistics alone, you could find plenty of evidence to back it up. In a side-by-side comparison of 2000 census data by sociologist John R. Logan at the Mumford Center, State University of New York at Albany, black immigrants from Africa average the highest educational attainment of any population group in the country, including whites and Asians."

Isn't fluid intelligence variable and hence working memory? Didn't they say that dual n-back can increase intelligence?

I wish they had an equivalent of dual n-back for motivation. I think I have always said it, people on HN don't need more intelligence; they more need to actually get things done.

The problem with motivation and anything technique related to it is you have to be motivated to execute said technique.

1. It takes on average 66 days for a habit to be formed.[1]

2. The intensity need not be there to form the habit. After a habit is formed you can increase the intensity of the activity. Start small like reading 2 pages a day and add a page every two weeks. This is probably the most important step.

3. Willpower is at a maximum right after waking, so whatever you are trying to accomplish do it first thing in the morning.

4. Stop dieting. It will burn through your willpower.

chegra84··on Why you should quit your technology job and get a Ph.D. in the humanities
There is nothing wrong with suggesting something radical. At the same time, you have to be able to show the strength of your beliefs. A strong signal of belief is your willingness to place money behind an idea. Probably the best example of someone placing money behind a radical idea is Peter Thiel when he created Thiel Fellowship.

I think you would be well received if you were to offer full scholarship and stipend equal to the participants salary.

chegra84··on "I Know Kung Fu"
Ok, I'm guessing the purpose of the post is exploring efficient methods of learning quicker.

Personally, I say tons of examples and exercises to test that you understood said examples.

For instance, someone gives you an api, but only gives you an explanation of the parameters. It is left to you now to figure out how exactly this api works(Does it take the full file path?, Is it the printer ip or the printer name? Is the array associative?) Now if I wanted to figure it out, I would draw from my experience how things like this normally works. Normally, it is two or three choices for every parameter and you fiddle with it until you figure out the correct format for what you are doing. So, with 4 parameters that is like 16 combinations, which aint so bad.

Now, if the creator of the api, had given an example of each unique way of using his api, learning the api would be much easier. Since now instead of debating what each parameter means and how to supply the given format, he can simply copy the example format[O(n)vs O(2^n)]. Learning without examples is an exponential function. Learning with examples is a linear function and learning matrix style is constant time.

[Did I just reduce all learning activities to be a function that takes parameters and to efficiently learn is to find an efficient algorithm to figuring out the best parameters?]

chegra84··on Show HN: my boilerplate CSS code for new designs, written in Less.
<Not Related>

Last weekend I finished reading "The Non-Designer's Design Book": http://www.amazon.co.uk/Non-Designers-Design-Book-Robin-Will....

So, I decided to test my newly formed designer skills and modify the look of the site here: http://i.imgur.com/k6y0g.png

The central point of the book is that we can tell when something is off with a design, but rarely we know how to fix it. So, yea this is what I thought need fixing on the site:

1. There is conflict between "What" and "Less Boilerplate" Header. Firstly, the fonts are the same size, so they are competing for who gets viewed first. Second, the orange on "What" is a warm color so it will stand our more, hence overpowering the header. So, I shrunk the "What" and increase "Less Boilerplate."

2. Too control the eyeflow from top to bottom, I increase the size of the navigation bar.

3. I increased repetition by changing the color of the header to white,the text to white and the separator in the navigation bar to white.

4.To highlight the "What" more I indent the text under it. And also set the text under it to be the same font size. There is no conflict here, since the header "What" is already highlighted alot.

5. To show what items that are important under "What", I bold the text that is not in the list.

chegra84··on My book (Essentials of Metaheuristics) officially in paperback
[Constructive Criticism]

1. Needs More examples - Examples gives a reader different avenues for understanding the problem better. Let's say they didn't understanding Genetic Algorithm on the first go, they would be multiple opportunity to understand it with more examples. Enhancing the chance that they understand the material and recommend it to friends.

2. Give real code - Readers might not exactly get how mathematical symbols turns into code, but I think they will understand real code. You want to lower the barrier of entry to read your material. Many programmers never took Calculus I and II and most start like 12, don't limit your audience by being opaque.

3. Give readers exercise to test their knowledge - Reader should have some sign that they are understanding the material and giving exercise show them gaps in their understanding.

4. Give it a different name - Maybe "Essential AI Algorithms","Genetic Algorithms, Simulated Annealing and others" or "Optimisation Algorithm Bible", so that you wouldn't have to explain what is Metaheuristic
