1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution.
2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20)
3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible.
4. Use [code] tags to format code blocks. |

programming nub w/ a question lol
so in java i figured out how to make a simple program that finds the distance between two points on a regular x y plane. however, the first time i tried it, the answer didn't come out right but when i just tweaked the formula, it's right.
1st method whose answer is off:
double x = Double.parseDouble(args[0]);
double y = Double.parseDouble(args[1]);
double a = Double.parseDouble(args[2]);
double b = Double.parseDouble(args[3]);
double Dformula = Math.sqrt(Math.pow((b-y), 2) + Math.pow((a-x), 2));
2nd method whose answer is correct:
double x = Double.parseDouble(args[0]);
double y = Double.parseDouble(args[1]);
double a = Double.parseDouble(args[2]);
double b = Double.parseDouble(args[3]);
double Dformula = Math.sqrt((b-y)*(b-y) + (a-x)*(a-x));
Why does the second method work, but the first one doesn't?
I just remembered, I have a 2nd question..why does System.out.print('b' + 'c'); produce a number?
First, next time put code in spoilers with proper indentation, its tough to read otherwise.
When you say that the first method doesn't give the correct answer, is it off by a tiny bit, or a huge amount?
Either way, I would try the first way with more careful use of parenthesis, like so.
double Dformula = Math.sqrt((Math.pow((b-y), 2)) + (Math.pow((a-x), 2)));
I'm not making any guarantees that this will work, but its worth a shot.
As for your second question, chars are stored as integers, according to UNICODE or some other character encoding. So Java defines 'b' + 'c' as 97 + 98 (in unicode anyways, exact numbers will be different in other encodings). You can get it to print a char like so:
System.out.print((char)('b' + 'c');
It should print whatever unicode 195 is.

3rd question:

double formula = Math.pow(cos, 2) + Math.pow(sin, 2);

Why isn't the answer exactly 1? this exercise even asks you why it isn't exactly 1. Also, how would you do this to make it always equal to 1?
The answer will not be exactly 1 because floats and doubles are not perfectly precise. They are VERY accurate, but not PERFECTLY accurate, so any answers produced with them either needs to use some rounding, or just accept the fact that a few of the right-most digits will be garbage.

Hey guys. I'm new to PHP, just wondering why this is happening. This form is a registration form. There is no MySQL code in it yet. I am just trying to validate the data properly and then I will struggle through the db code. I'm self taught with a few books, and I'm sure there are better ways to do this, but let's keep it simple please  . Also I'm sure the regular expressions aren't right either, I didn't read much about them yet.
Question: When I submit the form blank, why does the post password and post email if statements evaluate to true yet every other post related conditional evaluates to false? This is saying that $_POST['password'] and $_POST['email'] are set, but they should not be from what I can tell. Thanks for helping me understand!

actually all your isset($_POST[]) statements evaluate to true, because all of these are set to empty string, but only your password and email conditionals check whether there are certain characters in the string and therefor return an error message.

Hey TL!
I was wondering if there is anyone around here that could help me with some Actionscript 3.0 in flash.
Im making a simple game where to the player has to click away bombs before they destroy the city. (I know, its really original).
This is the first game im building on my own from the ground up, but im stuck.
+ Show Spoiler +
This is the function used for the spawning of the bombs:
public function SpawnBombs(Bombs:Number) {
for (var i=0;i<Bombs;i++) {
var Bomb:bomb = new bomb;
var score = i;
stage.addChild(Bomb);
Bomb.addEventListener(MouseEvent.CLICK, function(){
currentScore++;
scoreScreen.text = currentScore.toString();
startGameLoop(score);
});
}
}
I wrote the class called Bomb myself, that class contains the spawning position and the movementspeed.
But what i want to do, is to create a variable (a number) which keeps track of the amount of Bombs that have reached 940 px or more in the y axis. For instance:
+ Show Spoiler +
public var BombsonGround:Number = 0;
Bomb.addEventListener(Event.ENTER_FRAME, checkPosition);
public function checkPosition(event:Event) {
if (Bomb.y >= 940) {
BombsonGround++;
}
}
But the problem with this is, that if a bomb goes over 940px on the y axis, it will keep looping the IF loop and it will keep adding more and more to my BombsonGround value.
I hope i explained my problem well enough for people to understand, if anyone has any clue/idea/suggestion for this problem, please let me know!
Thanks in advance,
Syncope!

Use isset($_POST['submit']) on whatever you named your submit button to check if the form was submitted. If not, do whatever. If it was, use empty($_POST['username']) etc to check for data.

The other if statements don't run. I checked it with debugger, stepping through it all, and these two run while the others don't. I'll use the $_POST['submit'] method that tofu suggested, and it'll take less steps to load the page initially so that's good. I'm still wondering why this is though, for learning purposes if anybody knows. They are all set to empty strings when you press submit (without entering any data) but the If statements don't run on some and do on email and password.

Continue doing what your doing because no matter what it will help you in the long run. I know what your talking about and if I were I would continue using the Harvard course but also get you a APCS book, and look over it till either you finish the Harvard course of you think you have enough knowledge that you can move into the APCS book.
Also make sure that you take practice test so you dont take the test blind. Knowing what to expect will really help you.

Ok here's my new code. Is it better? Basically I added a name of 'submit' to the submit button and nested all the error checking inside the if ($_POST['submit']) statement. What should I do to improve it before adding database code? For those that didn't see my above post this is PHP and it is a website registration page. Thus far the intent is to validate the user input. The other functions called are kept in a code behind, and all it does is sanitize the strings so I can't get injected (I think anyway).
After much reading and web surfing, I cannot for the life of me find an article that agrees on how to check for a valid email address. Are these people just nitpicking at the articles for the lulz? Should I just find something that checks to see if it has an @ symbol and a (dot) something at the end?

Can you use code tags or put it in a gist next time? Absolutely awful to read as is
Anyway, your code looks fine. For checking a valid email address, most people use regular expressions ( http://www.regular-expressions.info/email.html ).
As an improvement, you should try and separate your content as much as possible from your code. IE: instead of echoing your form, put it outside of the php tags as regular html. Instead of setting error to some html, set error to just the error string, or better yet, an array of error strings and put it in your html like so:
<?php
[ ... your validation code ... ]
?>
<? if(count($errors) > 0) { ?>
<ul class="error">
<? foreach($errors as $error) { ?>
<li><? echo $error; ?></li>
<? } ?>
</ul>
<? } ?>

Speaking of VB, I had to use it last semester in my database management class.
It was not a good experience. The absolute worst part, was in Visual Basic for Access, it lets you use variables you haven't yet defined, unlike in pretty much any other language where the compiler would bitch at you. Instead of giving you an error, or crashing, it just ignores any statements with undefined variables.
Now, here's what happened to me. I had a major assignment, which was to build a program to allow users to access and use a database, while being restrictive enough that only valid data could be entered, and no data could be lost. I had done most of the work in other, shorter assignments already, the assignment was mostly just a lot of copy/pasting. Once I start testing it, I start seeing lots inexplicable errors. I even have the prof look at it; he suggests some fixes, and they help a little, but I still have tons of problems. 30 minutes before the assignment was due, I'm in panic mode, going over the code as carefully as I can, oh, and did I mention, this assignment was like, 20% of the final grade. Well, mere minutes before it needed to be handed in, I finally notice that when I copy/pasted everything, I missed the line:
Dim recCount as Integer
No line involving recCount was ever executing, and the compiler didn't think that was worth telling me........

Sorry I didn't know there was a code tag! I was looking for it but it's not a button and I didn't see it on the 'Smilies and BBCode' link either. I'll go edit my post now .
Thanks for the advice I'll definitely be doing this. This should make the code much easier to read. I have a very OOP mindset, having started with VB, C# mostly, but I haven't grasped the concept of how to apply this to the web. Really, I'd like to have the entire thing be a class, stored in a separate file (that the user can't get to) and just have it spit out the HTML to this php file. I feel like this is overkill though for a PHP page, the OOP (class, object, property, method) mentality doesn't seem to apply as easily yet for me. Does it for you when it comes to PHP? Maybe once my project gets more complicated it will? Also thanks for the link that's a good one to have for sure!
As for the C# vs VB debate, it seems like personal preference to me. I've read books on both of them and done a bunch of tutorials on both of them and they seem pretty much the same to me. Personally I liked VB 2010 more for Windows business type applications. It also made object oriented programming easier to see for me as it's using english instead of symbols. I'd say try them both and pick. I downloaded Visual Studio Express and just went to town on VB, C#, C++, and even ASP just to see which one I liked most.
Ended up on PHP... go figure.

What do you guys prefer between VB.net and C#?
In terms of usefulness and can open more doors for job opportunities. C#, absolutely no question. You probably don't want to do any of the jobs that involve using VB.NET, and C# is a much, much better language.
There is no difference between C# and VB.NET other than syntax. They will ultimately perform exactly the same. However, C# is the recommendation because: (1) there is an unfounded stigma that C# > VB.NET, hence most jobs are looking for the former, (2) C# background makes it easier to transition to other similar languages such as C and PHP.

Speaking of VB, I had to use it last semester in my database management class.
It was not a good experience. The absolute worst part, was in Visual Basic for Access, it lets you use variables you haven't yet defined, unlike in pretty much any other language where the compiler would bitch at you. Instead of giving you an error, or crashing, it just ignores any statements with undefined variables.

VBA != VB. Syntax may be similar but VBA is interpreted and therefore the compiler doesn't "bitch" because there is no compiler. There are plenty of scripting languages out there that assign default values to undeclared variables.
edit: vba is actually compiled into an intermediate language  . But still it just behaves like a scripting language, nothing out of the ordinary.

Hey guys, any idea how to mock databases in CodeIgniter/PHP, or how to create a fast in-memory one?
