How can I use functional programming in the real world? [closed]
...not contain any magic pixie dust that will pass functions off to different CPU's or machines. What F#/Haskell and other functional programming languages do is make it easier for you to write functions that can be processed independent of the thread or CPU they were created on.

What is the difference between an interface and abstract class?
...return this.fuel;
}
}
Implementing an interface consumes very little CPU, because it's not a class, just a bunch of names, and therefore there isn't any expensive look-up to do. It's great when it matters, such as in embedded devices.
Abstract classes
Abstract classes, unlike interfaces, a...

What and where are the stack and heap?
...ack
The stack often works in close tandem with a special register on the CPU named the stack pointer. Initially the stack pointer points to the top of the stack (the highest address on the stack).
The CPU has special instructions for pushing values onto the stack and popping them back from the sta...

Why must wait() always be in synchronized block
...the x-level cache (a.k.a. 1st/2nd/3rd-level caches) of the thread handling CPU core.
But synchronized blocks are only one side of the medal: If you actually access an object within a synchronized context from a non-synchronized context, the object still won't be synchronized even within a synchroni...

Static linking vs dynamic linking
... is usually negligible. Inside the DLL there is some more overhead on i386 CPU's, because they can't generate position independent code. On amd64, jumps can be relative to the program counter, so this is a huge improvement.
2) This is correct. With optimizations guided by profiling you can usually ...
