I think rigor is imposing to people when you try and combine it with high-level theory. The concepts in that article are built on top of so much theory, that to explain it all would require the equivalent of a course on analysis.
But if you supply rigor in an appropriate dose, it can really be eye-opening. For me, calculus was a nightmare because none of the terms used were well defined. I was just presented with all this highly developed theory and had to take much of it on faith. And I couldn't enjoy nor care about something I felt was just forced memorization of computational techniques for solving contrived problems. But if they'd done it rigorously, the classes would have begun with questions like "what is distance?", then answering that question would lead into "what is a space?", etc. This is rigor and I feel like exploring these types of questions is a lot more intuitive than forcing kids to memorize how to compute the volume of some cone.
I don't see much use out of either other than as a line on a resume. With that in mind, I'd choose IEEE - more well known than ACM. (And if you're getting the type of membership providing access to research libraries, IEEE will cover a far broader range of topics than ACM).
The comment that the link leads directly to is devastatingly good. If you don't want to do a lot of reading, just skip the main article and read that comment.
Yes. Completely happy. As everyone else said, the export to pdf is great.
No. I think SAT score would be correlated with IQ, but not too strongly on its own (many not particularly brilliant people get high scores by preparing excessively). I think measured IQ and family income would, together, be quite good predictors of SAT performance. But what leads me to believe that also leads me to believe that predictive strength would tail off as family income (or IQ) got extremely high. E.g., for very smart people, the SAT is probably not a challenge, so their score wouldn't benefit much from 10 more IQ points. Similarly, very rich people can't use their money to do much for their kids SAT score than those making $150k / year can.
But presumably average score for each group is used. I wouldn't think the difference in average score between the 200k group, and the 220k+ group would be great enough to cause that (and I don't think there'd be too many data points the farther you went out to have much influence on the average).
Unless they were using some type of weighted average for each interval and then skewed the $200k group by adding its weighted average in with the intervals beyond it, then averaging that. Which wouldn't surprise me given the appearance of the chart.
I thought the same, which caused me to click on the link they used as reference, which turned out not to work... <insert eyebrow raised emoticon here>
The only wierd thing to me is that the strength of the relationship appears to gradually weaken as income gets higher (which would make sense), but then sort of jumps up at $200,000. That's surprising, I would have thought the highest would have been around the upper middle class - comfortable enough to be able to dedicate oneself to school, but poor enough to still be hungry.
I'd like to see the relationship between extremely high SAT scores (e.g., 99th percentile) and family income. I suspect middle to upper-middle class students would proportionately outnumber the rich.
Yeah, good point, my advice is not particularly general. I guess I should also add, I've found most things not particularly enjoyable until I get a minimum level of skill. So if your a complete beginner jumping in for 10 hrs at a time might be a little much.
EDIT: ugh, this is not working right. I can't figure out how to get the asterisks to not italicize ( I was trying to show an example).
Variables have block scope, but storage duration need not. If you return a pointer to a block of memory allocated within a function, that is not undefined behaviour. If you return a pointer an array declared within the function that is (if you return a pointer to a static array declared within a function that is not). That's the contrast I was trying to point out.
In my experience, LONG practice sessions are much more effective than short ones. E.g., I've found I get far more out of one 8 hour practice session than four 2 hour sessions.
I'd also say you need to do it intensely - you've got to be into and "feeling" what you're doing. If you're just sitting there waiting for your 3 hours of "practice time" to elapse so you can go chill you may as well just not do it.
Thanks for elaborating.
I strongly recommend you find a trusted friend/family member/mentor/etc. to talk with about your concerns. It's really difficult to get a handle on a situation as complex as what you've described without knowing you personally. So I can't really say anymore than that.
But please do take my advice. I wish you well. :)
Also... Arrays have block scope. So if you have a function that declares an array, operates on it, then returns a pointer to that array, it's undefined behaviour.
This was very confusing to me when I learned C because it's one of those undefined behaviours that appears to work properly in trivial programs (at least with the compiler I was using).
But most people, IMO, do not think deeply about morality, they just mimic others around them.
I guess that would still apply to what you said though - it would take a very complex algorithm to come up with the optimal set of beliefs to minimize resistance you'd meet from others in the society you live in (I believe such an algorithm would not be unlike what goes on in the minds of many people).
What did you do that was supposed to be "impossible"?
What do you mean by "attacked"? (Phyiscally?)
"Controversies"?
The whole thing is very vague. :-)
With the exception of solving integrals, diff eqs, or other CAS things, is Wolfram Alpha particularly useful when you'd have google at your disposal? I would think no, but that's just my experience.
but the article said:
"the Supreme Court, in its 2003 decision in Grutter v. Bollinger ruled that diversity is a permissible objective for the use of racial preferences in admissions"
It's good writing I guess, but honestly they're trying too hard. It just sounds fake to be that over the top.
jeepers! Complimenting they guy and I get killed on the down votes??
How the heck is a preference in who you date "racism"? That's the stupidest thing I've ever heard. People have strong preferences over all sorts of superficial things - body type, hair color, hair style, breast size, height, etc. Is it really so hard to believe that someone's preference for XXXX skin tone is just as shallow as their preference for YYYY hair color? (I've yet to see a commenter to a survey showing men prefer blonds point to it as evidence of some deep seated prejudice/hatred said men have towards women of other hair colors.)
This sounds interesting. I've had a few unusual diets in the past, and found packing lunches the hardest part. What types of things do you take if you need to carry a lunch with you?
I love comedy, and would love to give it a try myself but (a) my sense of humour is very unusual and there's many things I laugh at hysterically that most people don't get, and (b) would be too nervous (sober anyways!).
An example of (a), I was at Subway the other day, and a 20-something girl was in front of me. The guy asked what kind of cheese she wanted, and she sort of hesitated and said "the uh, uh, the um, white triangles", which sent me into a fit of laughter, I thought it was the funniest thing I'd ever heard (can't wait to go to Subway again so I can use it). But everyone I told since sort of looked at me like "Uh, okay?". And I can imagine how well something like that would go over in front of a crowd of strangers, told by a scared shitless comedian at his first gig!
I've looked into it before. I concluded that it was not feasible unless you have an enormous amount of money (several hundred thousand) to invest as principal. I think poker bots have a way better risk:return ratio.
"Sue dough". For a long time I didn't realize it was an abbreviation for "super-user do", and by the time I did "sue dough" was stuck in my head.
I use a kneeling char (like Lisa Simpson has). It takes getting used to, but once your back, thighs, and stomach muscles have adjusted it feels really good.
Who says healthy food is more expensive? For $20 I can get enough bananas, oatmeal, tuna, eggs, and cucumbers to last me a week (easily). What's expensive is the great tasting healthy stuff - lean chicken breasts, sushi, good cuts of steak, exotic fruits and vegetables, etc. And this is a rude thing to say, but there's a lot of fat people who given a little more money would prefer an extra big mac and mcFlurry with their combo rather than wild rice and BBQ'd salmon.
