    UCF vs. FAU

    Exactly. Unfortunatly I haven't been able to find very much information the relative quality of the math programs at UCF and FAU, which is why I'm asking here. Though, relavance to my interests is my main reason for considering the transfer, since there's a lot of crypto-related activity...

    UCF vs. FAU

    Are you speaking generally, or specifically with regard to their math programs? You sound a lot like my coworker. She lives and breaths everything UF, despite the fact that she never went there. I don't really understand it, but then, I've never really cared about football or partying...

    UCF vs. FAU

    Earlier this year, I finished my AA degree from a community college and transferred to the University of Central Florida to major in mathematics. My plan is to finish my BS in math and attend grad school for math with a focus on cryptography. Admittedly, I haven't been at UCF for very long...

    Is it worth it to be in debt?

    To build on Cristo's comment - When I turned 18, I promptly moved 100 miles away from my parents. I got a job, rented an apartment, and found a roommate to offset rent and utility costs. I was still close enough to visit my parents when I wanted to, but far enough away that I could live my...

    PHP PHP Issue with my CMS

    Yes, the cart software is definitely what I linked earlier. The code is almost identical (some stuff was added to your version). checkNumber and isEmpty are both defined in library/common.js which should be included. For example, if I "view source" from the product add page, I see...

    PHP PHP Issue with my CMS

    I dropped your files into my test installation, went to the page, filled out the form, and was able to submit it (my db schema doesn't match yours, so I got DB errors, but that was expected). So as far as I can tell, the code you posted should work well enough to submit the form. This makes me...

    PHP PHP Issue with my CMS

    If there's no refresh (or page change) at all, then I'd focus on the javascript, since without a successful form POST, the PHP isn't getting executed. Out of curiosity, what browser are you using, and have you tried a different one? (in case of a browser-specific javascript bug) I've...

    PHP PHP Issue with my CMS

    @Borek - It looks like dbQuery (and the rest of the code, for that matter) is part of http://www.phpwebcommerce.com/shopping-cart-source-code.php" @bigdawg723 - I don't see anything offhand that would cause it not to work (at least nothing jumps out at me). More information about what you're...

    PHP PHP Issue with my CMS

    Two places to start. First, clicking the addProduct button invokes the javascript function checkAddProductForm() to validate the form before submitting. You'll want to make sure that's complete and working correctly (i.e., it submits the form after a successful validation). If this...

    Computer Science books for self-study

    Both books are used as textbooks by a number of universities. So, they're not what I would call "light" reading. If you're looking for an easy introduction, then they may not be a good fit. But in the event you want to dive in hard... they may fit the bill. I would suggest trying to find...

    Computer Science books for self-study

    I own both of these, and recommend them - https://www.amazon.com/dp/0201558025/?tag=pfamazon01-20 https://www.amazon.com/dp/0262033844/?tag=pfamazon01-20

    How valid is this?

    They may be logically consistent, but in my opinion, a number of his premises are flawed. A logically sound argument from a false premise is still a bad argument.

    How valid is this?

    I'm in a soulless, deadly position in industry, and am seriously contemplating trying to jump the fence to academia. Would you mind elaborating on this?

    Differential Equation Uses

    I'm currently taking ODE in college, so let's see if my education is doing me any good :biggrin: Let's say you have a derivative - f'(x)=3x^{2} That's easy enough to solve by integration -- \int f'(x) dx = \int 3x^2 dx f(x) = x^3 + C Notice in the original equation that f'(x) is ONLY...
