Is this still alive?
EDIT: Holy crap that was unintended. Bluh. XD

For the lower-level math students who are still having trouble grokking abstract variables, one trick I've heard of is covering up the letter with some symbol - a simple symbol or picture, or anything. That can give them a link back to what the variable is, and understand things a bit less abstractly, which they might be comfortable with. Then just pull away the picture, and hopefully kind of a "woosh" moment will happen to help them get the whole abstraction.

Do you realize that, with the ess-zett, it looks like GlaDOS waaayyy too much? ;-)

FizzBuzz is a good problem for... someone with one maybe a month of coding experience? I think it should be.
If you want to test a person's skill, give them USACO training problems! :-DD

If they haven't heard of "Djikstra's algorithm"... or they can't do something identical... teach it to them then and there, and if you're looking to hire, /don't/. :-P

Last year, first time getting a graphing calculator... got a TI-89... PROMISED not to lose it...
Lost it about a month later.

And, no, this doesn't have a happy ending. v_v

Web Programming and Design / Re: Making a webcomic: "dynamic hyperlinks"
« on: September 25, 2011, 09:26:57 pm »
Squidgetx, the reason that breaks your CSS is because that regex is too general... when the browser sends a request for http://www.shakespearescomics.tk/comic.css, Apache will look for http://www.shakespearescomics.tk/index.php?p=comic.css instead.
You could try
Code: [Select]
RewriteRule ^([0-9]*)$ /index.php?p=$1 [L] instead, this will only match numeric inputs.

I've used an Linux distro beyond Ubuntu... sadly... :-(
Ah well.
It's worked great for me, at least. Just another option I suppose.

As for the difficulty of adding a new comic - you could create a PHP page, sort of as an admin interface, to let you upload the file, and then automatically increment $max and store the title/alt text for you. Password protected, of course.
It might not work too well, if your web host doesn't let you do file uploads like that through some sort of stupid/weird restrictions.
Another way to make it somewhat simpler, perhaps, is to have a .txt file with all the titles and alt text (or a large number, 1 per comic), which the PHP script looks through. Also, just by checking if a file/line is present, it could then remove the need for $max.

You can do some fancy URL replacement stuff in what for you will probably be a .htaccess file. Googling for "RewriteRule" or "mod_rewrite" should tell you how; you can do stuff like making the comic URLs be http://www.shakespearescomics.tk/8, or http://www.shakespearescomics.tk/comic/8, or http://www.shakespearescomics.tk/hr7389i/uqhr8yug/lolol if you feel like it.

Miscellaneous / Re: Which TI calc do you hate?
« on: September 24, 2011, 01:18:53 pm »
At my school, there's this one teacher who is positively calculator obsessed - and he teaches Algebra/Trig, and so a lot of kids (like 90% of my friends [not a representative sample]) go through his class at some point. He actually has quizzes and such on different calculator-specific details..
Last year, unless you already had an 84, he made you get the nSpire... and this year he's making everyone get the CX.. :-(
Last year I'd gotten an 89 for my first calc... I lost it soon ( FACEPALM ), but a friend had a CASIO he let me borrow for the rest of the year. This year, I bought an 84SE, and during the third week of school traded with my friend cause I wanted extra RAM pages.

tl;dr LUDDITES FTW

Any chance of Still Alive? I've always wanted a good quality (but not as big as RealSound) version of that one...

Wouldn't f(x) be undefined for any x>=1? As you take it to successive powers, it alternates wildly between negative infinity and positive infinity (or at least negative one and positive one), so the limit wouldn't exist.. or am I missing something? :-/

Miscellaneous / Re: Do you think you are a nerd?
« on: September 22, 2011, 11:31:12 pm »
My school has the nerdy people, and the popular people; and we generally don't associate a ton I guess. It's a pretty large school, and so has a pretty large swathe of nerds, and we all hang out and enjoy and celebrate each others' nerdiness. Like, by wearing xkcd t-shirts, or by singing "Still Alive" together, or playing DnD, anything in that realm..

TI Z80 / Re: Zedd Physics Library (BETA)
« on: September 22, 2011, 11:27:48 pm »
I don't really know how the library works, but just as a suggestion for how a bugfix for the ropes might be implemented - Move the block one pixel in the direction of its would-be velocity, if it collides with anything, set the velocity to zero, /before/ moving it...

Like, if, normally it's done:
-Move object by vX
-If intersecting with something, inch pixel-by-pixel out (I hear this is how it's done) - then set the vX to 0.
-Do the same with vY

Then instead you could do:
-If vX=0, skip to vY;
-Move one pixel in sign of vX (i.e. if vX is 5, move 1; if vX is -13, move -1)
-If intersecting something, move that one pixel back and set vX to zero. Otherwise, move that one pixel back and move by vX.
-Do the same with vY

I don't know if the above suggestion would be compatible with however you're doing friction, but maybe it'll help. ^_^

Have you heard of the FIRST competition for high schoolers? My school has done decently, historically... and in two years I'll be making a robot. ^_^ (I'll be doing the programming, p > 0.95)
