How to create a file with a given size in Linux?

Why use Object.prototype.hasOwnProperty.call(myObj, prop) instead of myObj.hasOwnProperty(prop)?
...est for properties generally, e.g.
var o = document.getElementsByTagName('foo');
// false in most browsers, throws an error in IE 6, and probably 7 and 8
o.hasOwnProperty('bar');

// false (in all browsers? Do some throw errors?)

What is the difference between an expression and a statement in Python?
...ression is something that can be reduced to a value, for example "1+3" or "foo = 1+3".
It's easy to check:
print foo = 1+3
If it doesn't work, it's a statement, if it does, it's an expression.
Another statement could be:
class Foo(Bar): pass
as it cannot be reduced to a value.
