I'll end up just reading the crc32 from a file and use the rest for comparison.

More Success! A colored cube this time. :dance: However, can someone tell me why I didn't have to enable depth buffer? It seems that the depth buffer is enabled already and if I do:
[cpp]
glEnable(GL_DEPTH_TEST);
glDepthFunc(GL_LESS);
[/cpp]
it draws nothing instead. Does it have to do with the context setup that was done in open.gl that enabled depth testing or am I crazy?

Never mind, I just had to clear the depth buffer. However, how come depth testing is still enabled without me enabling it? (Or am I just lucky in drawing it in the right order)
Just found out today that you can document exceptions thrown (C#) using
/// <exception cref="ExceptionType">Information here</exception>
and there is intellisense for the xml comments.
I really need to look into the features of VS. I also never knew that you could type a method call and have intellisense create the definition (ctrl + k, m).
Bah, I also need to configure my hotkeys for some common tasks I do.
[QUOTE=Map in a box;31980033]How would you append the hash of a file to a file without changing the hash it already has? Cause:
CRC32 a file, prepend it. Oh no because you did that the crc32 changes. Might as well do this til the end of time![/QUOTE]
One solution is to reserve a set amount of bytes at the start of the file for a hash. When calculating the hash, disregard the space dedicated to hash storage.

[QUOTE=bobthe2lol;31978737]Speaking of big bangs, I have a question. I know this isn't really programming, but w/e. Theoretically, in a really long-ass time from now, wouldn't the gravity of everything in the universe draw everything in the universe into a single point? This point would be infinitely small, and would contain all the matter and energy in the universe. Since it contains all that in a single point, wouldn't that mean that when it exploded, it would explode in a predictable way? And doesn't that mean that I have typed this many times in the past, and will type it infinite times in the future? Wouldn't the universe expand because of the force of the big bang, then contract to a single point, then expand...ad infinitum? Sorry if that doesn't make sense...[/QUOTE]
Not necessarily, and here's why:
Acceleration is the derivative of velocity with respect to time, and gravitational acceleration is inversely proportional to the square of the distance. c0 is a constant that encompasses the mass of the attractor, the gravitational constant and the direction of the acceleration (in its sign). They don't really matter.
[img]http://latex.codecogs.com/gif.latex?a%20=%20\frac{\mathrm{d}v%20}{\mathrm{d}%20t}%20=%20\frac{c_0}{x^2}[/img]
We can apply the chain rule:
[img]http://latex.codecogs.com/gif.latex?\frac{\mathrm{d}v%20}{\mathrm{d}%20t}%20=%20\frac{\mathrm{d}%20v}{\mathrm{d}%20x}%20\cdot%20\frac{\mathrm{d}%20x}{\mathrm{d}%20t}[/img]
And since velocity is the derivative of position with respect to time:
[img]http://latex.codecogs.com/gif.latex?v%20=%20\frac{\mathrm{d}%20x}{\mathrm{d}%20t}[/img]
We get:
[img]http://latex.codecogs.com/gif.latex?\frac{c_0}{x^2}%20=%20\frac{\mathrm{d}%20v}{\mathrm{d}%20x}%20\cdot%20v[/img]
[img]http://latex.codecogs.com/gif.latex?\frac{c_0}{x^2}%20\mathrm{d}x%20=%20v%20\mathrm{d}v[/img]
[img]http://latex.codecogs.com/gif.latex?\large%20\int_{x_0}^{x(t)}%20{\frac{c_0}{x^2}%20\mathrm{d}x}%20=%20\int_{v_0}^{v(t)}{v%20\mathrm{d}v}[/img]
[img]http://latex.codecogs.com/gif.latex?-\frac{c_0}{x(t)}+\frac{c_0}{x_0}%20=%20{1\over2}v(t)^2%20-%20{1\over2}{v_0}^2[/img]
If we try to let time go to infinity
[img]http://latex.codecogs.com/gif.latex?t\rightarrow%20\infty[/img]
We let velocity decrease to zero at infinite time
[img]http://latex.codecogs.com/gif.latex?v(t)%20\rightarrow%200[/img]
And assume that position goes to infinity at infinite time
[img]http://latex.codecogs.com/gif.latex?x(t)%20\rightarrow%20\infty[/img]
This equation gives us
[img]http://latex.codecogs.com/gif.latex?\frac{c_0}{x_0}%20=%20-{1\over2}{v_0}^2[/img]
I.e.
[img]http://latex.codecogs.com/gif.latex?v_0%20=%20\sqrt{\frac{-2c_0}{x_0}}[/img]
Which is a completely valid solution. It means that there exists an initial velocity that allows an object to escape to infinity from gravitational acceleration with a real-valued velocity. Note that c0's sign must be negative, i.e. gravitational acceleration must occur against the initial velocity.
