My parents think that I don't work at all, and I prefer to keep it that way, at least, until I achieve some measure of financial success.
What is the Less Wrong Study Hall?
My workflow is that I spent 30 minutes a day going through the cards. I do them all until I complete them. Usually, that mean I finish them all within 30 minutes. If there's spare time, I learn some new cards until 30 minutes is up. Otherwise, I never learn anything new that day. Over half of the content entered is never reviewed before, so I have quite the reserve.
Usually that mean hundred of cards are studied everyday. Then I spend 5 minutes editing my cards, either for errors, or for fact checking.
As much as I like reading the sequences, I am skeptical about their utility in increasing rationality, or rather, the rationality increases in the lesswrong community is not measured or quantified scientifically.
Depends on what you mean by "a systematic manner". If there's a large subject I want to go through, I'll start where I think I'm already up to, work my way through the videos one by one, skip topics I'm already happy with, and continue along those lines until I'm satisfied. If there's a small subject I want to go over, I'll identify the appropriate videos and watch them all.
It wouldn't be a productive use of my time to go through every single Khan Academy video one by one, as I'm already most of the way through a maths-heavy undergrad degree.
Well, I meant doing the exercises. I don't spent much of my time on the videos because either I already know it or I figured out either with the hints or without. Then, it's smooth sailing the rest of the way.
I'm attempting to use it alongside Udacity to grasp Maths, Science, Statistics and Computer Science (well, programming). I've not got down to doing everything systematically yet, but it's all much more effective and efficient than school (I'm 15). Currently, I'm learning Calculus, and it's much better than the English education system, even though I have a one-to-one session for one hour per week with my teacher. On Khan, I have an Earth Badge, and 66,858 points.
Well, since I am almost complete the whole thing, I have 1.3 million energy points, and 4 suns and 2 earth badges in additions to all the moons and the meteorites.
Is what you said true even if you go into a field, or choose a major, that relies heavily on advanced math? That was what I was trying to get at. If people do much more complicated math on a daily basis, presumably they have already mastered all math topics at a high school level, unless the skills they use are much narrower than that (which, of course, might very well be true).
That's a question that cannot be answered without looking at math major's area of focus or their specific career of choice, of which I am ignorant about.
That being said, I don't think a math major or a person who is in a strong math related field necessary focus on everything that requires high school mathematics. They may not touch statistics, or linear algebra as often as other area because they don't need it in their day to day job. They may need khanacademy to reviews those area that they didn't touch.
In a highly technical field like programming, most programmers may not need to deal anything more complicated than algebra, so they're going to forget the more advanced aspects.
It's helped me tremendously - just started university, and we had a teacher who just wasn't that good. Nice person, not enough teaching experience. Looked up Khanacademy, and a second explanation made it stick. I'll use it to repeat things later on. Started peeking into javascript too, as I've yet to write a single line of code in my life, it's a much appreciated source of information.
Did you do any of the exercise? How much if you do so.
I used to go on Khan Academy pretty often earlier this year, but now I usually learn by means of a textbook + writing down exercises in a notebook. Earned 2 Sun Badges and about 350k energy points so far, if you're interested in hearing about some measure of progress.
It's absolutely awesome for high school students, but it doesn't look like it can help much past the freshman or sophomore year in college. (Then again, what the heck do I know?) If LessWrongers are, on average, as good at math as I estimate them to be, then only the youngest of us can derive much benefit from it.
I don't think khanacademy is just for high school kids, or elementary or middle school. Everyone will forget, and almost everyone with a high school education or better will have gaps in their knowledge. Everyone seems to think that college is the end of their education, but that's false. As with everything you learn or master, you need to practice them, and khanacademy offers periodic reviews according to the principle of spaced repetition.
So, it's great for adults too, even if they're only in review mode for the vast majority of their life. When they start to learn something more advanced, they don't have to go back to elementary math or deal with the problem of knowledge gaps.
Only the youngest can derive much benefit from it? Absolutely not true.

I recently started using Habit RPG, which is a sort of gamified todolist where you get gold and XP for doing your tasks and not doing what you disapprove of.
Previously I had been mostly using Wunderlist (I also tried Remember The Milk, but found the features too limited), and so far Habit RPG looks better than Wunderlist on some aspects (more fine-grained control of the kind of tasks you put in it, regular vs. one-off vs. habits), and of course has an extra fun aspect.
Anybody else been trying it? (I saw it mentioned a few times on LW) Anybody else want to try?
I didn't tried it, but I believe I wrote my own gamification system. It is a simple time tracking system with a history viewer, from which I clock in my activity for the day. I have my own goals that I tried to achieve everyday. It was very effective in keeping me working 30 hours each week for 7 weeks so far.
