Why is my variable unaltered after I modify it inside of a function? - Asynchronous code reference
..."callback" to a function that is essentially a black box (implemented in C etc..). To the hapless developer they are async...just because. If you want to write your own async function you have to hack it by sending it in to SetTimeout(myfunc,0). Should you do that? Another debate....probably not....
How to use glOrtho() in OpenGL?
... every time I need to do 2D graphics in OpenGL (such as health bars, menus etc)
using the following code every time the window is resized:
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0f, windowWidth, windowHeight, 0.0f, 0.0f, 1.0f);
This will remap the OpenGL coordinates into the equ...
JavaScript closures vs. anonymous functions
...lexical grand parent function, in the lexical grand-grand parent function, etc.
This can be seen as a scope chain; scope of current function -> scope of lexical parent function -> scope of lexical grand parent function -> ... until the last parent function that has no lexical parent.

Understanding recursion [closed]
... then call writeNumbers(9) which will write 9 and then call writeNumber(8) etc. Until writeNumbers(1) writes 1 and then calls writeNumbers(0) which will write 0 butt will not call writeNumbers(-1);
This code is essentially the same as:
for(i=10; i>0; i--){
write(i);
}
Then why use recursion ...
Difference between CouchDB and Couchbase

How exactly does the callstack work?
...de a frame appropriately to optimize their alignment so the processor can fetch them as quickly as possible. The crucial fact is that the offset of the variables relative to some fixed address is constant throughout the lifetime of the frame - so it suffices to take an anchor address, say, the addre...
