Text may look like more like an icon (as in the Japanese example) or an icon may look like text (as in a jpg button that says "Submit" or a cat photo with an overlaid caption) or text may be replaced o...
Determining complexity for recursive functions (Big O notation)
... o);
recursiveFun4(n-1, m, o+1);
}
}
Here, it's O(2^n), or exponential, since each function call calls itself twice unless it has been recursed n times.
int recursiveFun5(int n)
{
for (i = 0; i < n; i += 2) {
// do something
}
if (n <= 0)
return 1;

What does `someObject.new` do in Java?

@EricJablow indeed, it's one of those bits of syntax that has to exist to keep the spec consistent but 99.9999% of the time you don't actually need to use it. If outsiders really need to create Bar instances then I'd provide a factory method on Foo r...

How to REALLY show logs of renamed files with git?
...g files; git doesn't really care which file you consider renamed and which one you consider copied (or renamed and deleted) it just tracks the complete content of your tree.
git encourages "whole tree" thinking where as many version control systems are very file centric. This is why git refers to "...
How do emulators work and how are they written? [closed]
...tion is a multi-faceted area. Here are the basic ideas and functional components. I'm going to break it into pieces and then fill in the details via edits. Many of the things I'm going to describe will require knowledge of the inner workings of processors -- assembly knowledge is necessary. If I...

Interfaces — What's the point?
... @BolucPapuccuoglu: Beyond that, with a statically-typed object if one knows foo implements IWidget, then a programmer seeing a call to foo.woozle() can look at the documentation for IWidget and know what that method is supposed to do. The programmer might have no way of knowing where the c...
