I've never come across a keypad lock that would be vulnerable to this. You either have to press # at the end of the code, or the codes are significantly longer than 4 digits. Of course, even in the first category, entering 24 codes (50% cha

I use Google Gears, so I can still access all of my mail. I'm sending e-mails from a mail server on my laptop, but I could just as easily use a different e-mail service while gmail is down. Yes, Google is a big company with lots of technica

Nope. I'm well aware that people still study analysis. I just meant that one doesn't necessarily need to learn calculus before taking the plunge into serious mathematics. Even in analysis, there's quite a bit you can do without knowing the

That post does not contain any advice. It contains facts, none of which were contradicted by your post (a typical property of facts). I never told him not to study calculus. Given our current education system, that would be impossible anywa

I'm aware of their applications; by "practically", I meant "almost". There are certainly compelling uses for number theory and combinatorics (though I'm not convinced the study of algorithms is one of them), but they're nothing compared to

No. Many pure math classes require no (or very little) calculus. Abstract algebra, number theory, combinatorics, and graph theory certainly fall into this category. Topology does, too, depending on which area you study and what you consider

Putnam problems are not considerably harder than AIME problems, and AIME is definitely the next step from AMC12. Anybody who can solve a few AIME problems can certainly solve A1 on the Putnam of almost every year.

To be honest, calculus isn't that important for mathematicians, but if you want to study mathematics seriously, I'd suggest picking up a rigorous text like Rudin's or Apostol's. It will be difficult. You'll have to read most of it several t

No, x = -1/4 is correct. Perhaps you should look up the order of operations.

I'm not willing to concede his point yet, but even if he's right, this should be implemented by the browser, not the website. And if you consider taking his advice, I suggest masking the password as soon as the input field loses focus.

Me too, but I use more like 20 minutes per month. (Seriously, who needs a phone? That's what the internet is for.) The great part is that I can buy $10 worth of minutes at the end of the year, and all my minutes last another year. So, after

I agree, up to perhaps a log-log scale. My grammar isn't likely to be significantly better in 30 years. However, when comparing among groups with similar English experience, grammar is likely to have a reasonable correlation with well-struc

Read the notes: http://www.paulgraham.com/saynotes.html [15] By this I mean you'd have to become a professional controversialist, not that Noam Chomsky's opinions = what you can't say. If you actually said the things you can't say, you'd

Downtown San Diego is a long trip for nightlife. Most students probably won't have a car (parking is ~$600), so it'll be over an hour on the 30 each way (150 doesn't run at night). I don't even know how to get to PB by bus. My friends who l

Full disclosure: I'm a math PhD student at UCSD. UCLA is probably better overall for math, but UCSD is better for graph theory and combinatorics in general, the most likely kind of math CS students would be interested in. In my opinion, the

Agreed. Some of Coding Horror's material is certainly worthwhile. For example, I know I found out about the HttpOnly flag in cookies from him, and I'm pretty sure I've learned of some usability improvements from his articles as well. Howeve

I like it. Most things I play with a projector don't start with higher than 640x480 resolution, anyway, so the picture quality is actually quite good. It tends to get a little hot, which causes me to worry, even though I'm sure the engineer

I have a 3M MPro110. It's 640x480 (vs. 480x320) and about $350 (vs. $430). Also pocket-sized. I don't see the comparison.
