What are the main uses of yield(), and how does it differ from join() and interrupt()?
...nd Java 6.
In Java 5, Thread.yield() calls the Windows API call Sleep(0). This

...s going.
Example to clarify things:
Say we have a server at 192.168.1.1:80 and two clients, 10.0.0.1 and 10.0.0.2.
10.0.0.1 opens a connection on local port 1234 and connects to the server. Now the server has one socket identified as follows:
10.0.0.1:1234 - 192.168.1.1:80
Now 10.0.0.2 open...

Why is XOR the default way to combine hashes?
...om (1-bit) inputs, the AND function output probability distribution is 75% 0 and 25% 1. Conversely, OR is 25% 0 and 75% 1.
The XOR function is 50% 0 and 50% 1, therefore it is good for combining uniform probability distributions.
This can be seen by writing out truth tables:
a | b | a AND b

Delete element in a slice

So what this line does:
a = append(a[:0], a[1:]...)
is essentially:
a = append(a[:0], a[1], a[2])
Now, you may be wondering, why not just do
a = append(a[1:]...)
Well, the function definition of append is
func append(slice []Type, elems ...Type) []Type
