Good ways to manage a changelog using git?
...l create a "change log" containing lots of entries like "Fixed spelling of fooMethod in ZModule" and "Refactor XModule to use new version of XYLibarary". Your users don't care about that.

Does a method's signature in Java include its return type?
....
Since the question was edited to include this example:
public class Foo {
public int myMethod(int param) {}
public char myMethod(int param) {}
}
No, the compiler won't know the difference, as their signature: myMethod(int param) is the same. The second line:
public char myMeth...
In plain English, what does “git reset” do?
... shouldn't be too surprising.
For example, git reset other-branch path/to/foo resets everything in path/to/foo to its state in other-branch, git reset -- . resets the current directory to its state in HEAD, and a simple git reset resets everything to its state in HEAD.

...ey can be used on array-like objects e.g. Array.prototype.indexOf.call({0:'foo', 1:'bar', length: 2}, 'bar') == 1;. The arguments object is also a good example. For pure array objects, it's impossible to change the type of the length property, because they implement an special [[Put]] internal metho...
What does the caret operator (^) in Python do?
...ns exponentiation. You could do that this way, just as one example:
class Foo(float):
def __xor__(self, other):
return self ** other
Then something like this will work, and now, for instances of Foo only, the ^ symbol will mean exponentiation.
