Exposing children to too much within a short time - which tends to happen in their teenage years as they become more mature - does overwhelm children. They may not have the mental tools and the feeling of not being able to comprehend or cope may give rise to negative emotions - guilt and insecurity. In the pre-teens and early teems, how information is presented to the child depends on the parents. The influence of the school, peer pressure, etc starts taking over pretty soon. While keeping the children away from everything in a sterile environment is not correct, there is nothing wrong in choosing the right time and place to help them learn. Finding out their reactions to various things, and explaining there could be many ways to approach something of which some ways are better than others, etc. takes time, effort and patience. As an involved, committed and hopefully intelligent parent, there are times when I have to resort to saying "Oh, thats a bigge thing - you will learn it soon!". To me that is not a lie - that is like saying first learn your A, B, C. then you can read that very colorful picture book and enjoy it.
Not pure maths, rather applied, but one would have to mention the Landau course as sharing those characteristics.

Superb hosting review
http://www.superbhostingreview.org is superb hosting review and superbhosting coupon site, hosted with superbhosting.net.
These strong-typing/weak-typing debates are the programmer's equivalent of skirt-length trends. The strong type system of C++ was a direct reaction to the deficiencies of the cast-happy, C-style of coding that came before; now we're back to dynamic typing. Ten years from now, after this generation of college grads has been burned while using the latest silver bullet for real projects, we'll be back to something more static. And around we go...

Anyone who experienced the C->C++ transition can tell horror stories about problems due to the (ab)use of C's type system in real code...and C wasn't even that weak! Even Perl coders have learned this lesson the hard way (hence the introduction of "use strict"). But I digress.

Maybe you're right, and strong typing doesn't matter that much for the new generation of apps. My instinct however, is that the current hipness of dynamic typing is a (somewhat justified) over-reaction to the ugliness of C++. Meanwhile, a lot of babies are being thrown out with a little bit of bathwater....
I got it I think and still open up the books every now and then, but it was about topology and model theory that I started to question its applicability.
I remember asking my lecturer this (I could have phrased it a little better in hindsight, I sort of burst out during a lecture 'whats the point of this' The lecturer got a little upset :-)).

Transfinite numbers are always my favorite example of something way out there, different sorts of infinities and which infinity is bigger than the other, the models are beautiful, but I couldn't spend my life arguing about them. I think for most people maths starts losing its relevance a lot earlier, it justs takes some longer to admit it, because it's prettiness is so seductive :-).
How does Twitter do this?
I am just curious, how does twitter send "twitts" to users of the service? Do they have an SMS server farm? i.e. computers attached to GPRS modems connected to the web? or do they just buy sms units from whole sellers? if they do so, it must be pretty expensive and do they make any money at all?. If anyone has any info about the inner workings of Twitter, i will love to have it. thanks

funny, I always thought it was the other way around, calculus was just a clever calculating trick, but give me a good algebra, then we can really do something :-)
Until you get RSI.
Wasn't really my point, I just took the diversion to talk about static typing. If static typing comes back as the thing I think C++ will still be crap. I think the productivity gains in the language I mentioned have everything to do with built in list types, first class functions, closures and anonymous functions. Good libraries built on those things help a lot as well.

Human dynamics revealed through Web analytics
For whom, though? Brains are complicated, but if yours is severely damaged (through a stroke or head injury) motivation is not necessarily going to fix that. And as far as I know, there aren't any permanent ways to raise IQ. Some environmental factors lead to higher childhood IQ, but these vanish by adulthood. And there are tricks people can use to bump up their scores on IQ tests, but I haven't seen a situation in which practicing for test A raises your score, years later, on test B. This stuff is just more static than that.

The danger with what you're saying now is that someone with an IQ of 90 -- someone who could be a fine contributor to society in lots of practical, necessary fields that don't require lots of abstract thinking -- could be inspired to throw away lots of time and risk lots of frustration trying to be a mathematician. We should deal with the fact that wasting education on someone who can't use it is as much a tragedy as failing to educate someone who can use it. By pretending that 'smart' just means 'trying hard', you're doing more harm than good.

Wouldn't this fly in the face of common carrier regulations and subject the telecoms to massive taxes/fees/penalties and congressional litigation for stymieing small IT/software businesses? The government would probably put a stop to this, if only for the purpose of competing economically against China/other countries (I'm talking about the US here). We'd be at a severe technological disadvantage, lose potential taxes on new business, and go against all of wall-street (internet ipo's would essentially cease).

7 Tips for Amateur Type Designers
I don't know exactly about the inner workings of Twitter, but whenever I picture it in my mind I imagine a lot of 2nd-rate servers stacked on a table with covers missing and cables snaking around. The lights on the SMC switch from ebay blink frantically while several admins bang feverishly on random keyboards, uttering multi-lingual curses.

Of course, it could be different, but probably not by much.
I did not want avatars per se, though they would have probably fulfilled my request. All I was asking for was some pictorial cue to better associate user names with their set of comments. It could be randomly generated. It is a memory thing.

That being said, humans have evolved to remember faces at a very intricate and ingrained level, so perhaps faces would be best. In any case, I said "pictures next to user names," not avatars.

What I was looking for seemed to get lost in peoples' emotional reactions to digg and other social networking sites, as they are here.

Once you know you like submissions/comments of certain users, I think it would nice to be able to follow them more easily than going through each, one by one, manually. I think this could be done very differently than a buddy list, e.g. an RSS feed or the exact same interface filtered with those users or somehow promoting them.

I don't know if I topped-out, but I did lose interest. Calc III felt hard with not very much useful information (my comp sci advisers basically gave me grief for taking it). Linear Algebra sparked my interest again, but only because it started out wicked hard and then (just like with Calc years before), it just "clicked" and suddenly it was a lot easier/interesting. I didn't pursue further because after I graduated I preferred diving into new compsci (and engineering) concepts rather than focusing in math areas.

It's almost certain that they use an SMS gateway. You can bulk buy messages and get significant discounts. Much cheaper then rolling your own.

Startup Name?

Here is a pop-sci version of some recent research:

http://www.sciam.com/article.cfm?id=the-secret-to-raising-sm...

However, this isn't particularly surprising. Research on "grandmasters" in many activities, like chess or pilots, usually shows they've put in 25K hours of practice in their field.

I'm certainly not in favor of saying anyone can do anything. Especially in physical activity. There are definitely physiological advantages.

The same is also true in mental activities to some extent. A kid with down syndrome probably isn't going to become a math professor. However, I think the point is that most normally developed folks probably haven't hit a ceiling in their math aptitude. They just stopped caring or putting in the effort.
> However, I do agree with the conclusion. For web-based programming, object oriented programming is simply ridiculous in all but a small number of cases.

I read his conclusion as that object oriented programming has failed us because it is too hard to understand, and we need a new, simpler, more accessible, dumbed-down programming paradigm. He is advocating programming for non-programmers, which has been tried many times before and has always met the worst kind of failure (universal disdain by "real" programmers).
My nephew started college last year. When he was at home his parents monitored his Internet time. Now, armed with a new Apple acquired as a present and unlimited Internet access supposedly given because students have to research his head is filled with distractions. Every attempt at making him do some real work is refuted with something like - "but, this is archaic stuff - just pick it off the net from here" or "hey, give me a few min and I can grab it off the net" or worse still "someone stole my idea!". Absolutely no work and lots and lots of fluff in his poor head.

Actually, there was a recent article on YC news about the large number of discoveries that were made independently at almost the same time.

Our made-for-tv histories usually show a lone scientist toiling away for years, making huge discoveries. But in reality, most discoveries are incremental. The stories we are taught about these discoveries are usually mythologized.

It is true that there is some level of creativity needed. But it's probably way more common than our histories would lead you to believe. The recurring theme you will hear from scientists is that "chance favors the prepared mind."

I liked that bit, too, although I thought the stuff about PhDs a bit overstated, maybe because Dyson doesn't have a PhD. But the snobbism about invention seems oh-so-true, and to have dire consequences for academic disciplines (e.g., CS) where invention is particularly important.
Best Text Editors
I'm not sure I ever had that reaction. I explored a few topics in different lectures in grad school which were pretty obtuse: ergodic theory, for example. I didn't get it, but I assumed it was because the topic wasn't suited to lectures, and after learning of the basic direction they were headed in and setting out myself, I found I could get pretty far.

I've seen others give up on some topic rather than the method they used to try to understand it. It's the equivalent of someone saying "I can't get math" because they're spending all of their time remembering formulae, or someone saying "I'm no good at programming" while spending their time reciting bubble sort line by line in preparation for the exam. Giving up on higher mathematics is like that. Almost always, there's some path to real understanding -- you just have to find it.

someone should download the periodic backups and analyze all posters contributions (setting up synonyms, word-topic groupings etc.) and thus associate a user with an image based off a google image search + grease monkey script for hn. You would obviously want to avoid using the same image twice. You could keep a record of the past images associated with that user as a way to visualize their shift in interests etc. But that would fit your needs with out turning it into a way for people to "express themselves man".

It might also be a function of where his interests are now. I was a bit surprised too, since grad programs in physics are pretty honest. But I think it's a little different in bioscience. On many occasions, after talking with a biologist or biochemist, I get the impression that it must be incredibly hard to stay focused on the interesting questions. There is so much pressure to pick safe topics and just churn out papers.
Ask Students: How to organize and share notes?
I'm currently thinking about setting up a wiki for our university where all students can share their notes which they've taken in class.
I would say that 80% of our professors provide the notes in a digital format, but there are still those 20% which sadly don't.
Most students also take their notes just for themselves instead of collaborating on Google Docs or something similar.

My question is: Does your university provide a way to share (written) notes? If yes, which experience did you make with it?

Don’t do Startups, Buy a Business..?
I really hate to say this, as much as I like object
oriented programming but, I really think we might be better
off if we went back to procedural programming for the bulk
of the applications that we write and left the object
oriented stuff to people who really understand it and for
problems that can not be solved any other way.

Meanwhile, back at the lab, we need to come up with a
programming environment that most people understand
naturally. We need to do usability studies on the
languages we develop just like we test applications we
develop for users. Instead of trying to simplify what we
are already doing, which continues to provide solutions
that only programmers understand, we need to provide
solutions that are no longer programmer centric.

Isn't this what we used to call Visual Basic?

I've been having to work in MFC recently for a client, and boy...

If you ever needed a reminder why some people dislike C++ so much, just work with MFC. It's one of the worst bastardizations of C++ I've ever seen (of course, to be fair, one has to admit that much of the really sucky stuff in MFC was done before the C++ standards were very good, and long before the compilers caught up).

Writing C++ using std:: and boost:: and other libraries written in "Modern C++" is pure bliss compared to doing it the "Microsoft Way".
