How to specify function types for void (not Void) methods in Java8?
...patible with that you are looking for:
interface Consumer<T> {
void accept(T t);
}
As such, Consumer is compatible with methods that receive a T and return nothing (void). And this is what you want.
For instance, if I wanted to display all element in a list I could simply create a consu...

printf with std::string?
...e and typesafe. In fact, when you're writing C++, you generally want to avoid printf entirely -- it's a leftover from C that's rarely needed or useful in C++.
As to why you should use cout instead of printf, the reasons are numerous. Here's a sampling of a few of the most obvious:

What is an uninterruptible process?
... process which tells the cpu to slow down a bit and sits in a loop — the idle loop).
If a signal is sent to a sleeping process, it has to be woken up before it will return to user space and thus process the pending signal. Here we have the difference between the two main types of sleep:

Next up: (2). locals() provides a dict of the current scope. Thus, in a method that has no other arguments, you have self in scope, which contains a reference to the current instance. The trick being used that is stumping you is the string formatting u...

...d to do is implement a custom container view controller - lets call it SideBarViewController - that swaps out which of several possible child view controllers it shows, almost exactly like a standard Tab Bar Controller . (It's pretty much a Tab Bar Controller but with a hideable side menu ins...
Find XOR of all numbers in a given range
...e every 4. So, that's how to arrive at that little lookup table.
Now, consider for a general range of [a,b]. We can use f() to find the XOR for [0,a-1] and [0,b]. Since any value XOR'd with itself is zero, the f(a-1) just cancels out all the values in the XOR run less than a, leaving you with the X...
