I have a quick question about boolean expression:

! ( True || False) evaluates to False.
! ( ( true || false) && false ) evaluates to True.

But why is that?

I was reading jumping into C++ and there were some examples of boolean expressions. Can someone help me out?

Hello, I've found myself coding a lot of PHP lately and I've been wondering what is a better practice:



Note that the example code is simple, but I mean what would be preffered when we are dealing with much larger scripts?

Personally I find [1] to be much more readable, while theorically [2] should be more efficient. Is there a coding standard or do programmers just code as they please?

R1CH, by your wizardry powers, if you are reading this, what do you recommend?

Im looking to do some c++\openGL game related programming. Does anyone have any suggestions for a cross platform library (or libraries) that can do windowing, input, and sound. And before someone says I should use an engine like Unity, or a different language - half the point of doing this is I'm interested in the low level game systems like managing the input/threading/audio streams

Windows APIs (not multi-platform, but oh well - I can encapsulate the code anddeal with porting the code if I ever want to port it)
SDL - started working with it but had some troubles getting it set up on windows and visual studio, but otherwise it looks like it would meet all my desires.
Allegro - can be used with openGL, but the documentation of using allegro with openGL (2d or 3d) is pretty sparse

I have also considered using openAL for 3d positional sound, but that will likely come after I get some of the other systems working

Anyone have other suggestions, or experience with the mentioned libraries.

You can pick any EMACs tutorial from google for the basic stuff (the first search hit is decent), but the power of emacs comes with all the plugins which depend on the language you want to use. Once you understand buffers and remember the shortcuts you should be set to go.
However I would not recommend to use EMACs unless you really have to (i.e. you do erlang) Eclipse is a far better option in most cases or vim is sufficient for the extra trivial stuff

Either one is a godsend when you end up having to code something quick over a spotty remote connection.

Or you know, you could just code it on localhost and upload it.

Has anyone worked with Google Maps api or any other street maps? I'm trying to create a tower defense game, but instead of making levels myself, the user will be able to select a location somewhere, and it will generate a level based off the roads (one ways and overpasses will work as intended). Has anyone had any experience with this kinda thing?

I hope it's kosher to ask HTML related questions here. I can't figure out this seemingly simple problem where I have a div that is fixed to the bottom right of the page (where there is a shopping cart widget from WordPress). So the CSS is

#footer-cart { position:fixed; top: 93%; left: 70%; }

Now when people add an item to the cart I want it to expand vertically, since it's fixed on the bottom. I also have the cart on the non home page where it's fixed to the sidebar and when items are added it expands downwards naturally.

#footer-cart {
    position: fixed;
    bottom: 0;
    right: 0;
}

If you want it fixed to the bottom-right, you should probably be using the bottom and right attributes, instead of top and left, IE:

#footer-cart {
    position: fixed;
    bottom: 0;
    right: 0;
}
