If you can let go "drilling down" into the code, then you'll find scanning a code with let() declarations much, much faster. It is easier to pick out let() declarations when scanning code than to find @variables embedded into the code. Using @variables,...

IPC performance: Named Pipe vs Socket
...f cases I've seen.
If you really think that sockets are going to slow you down, then go out of the gate using shared memory with careful attention to how you use locks. Again, in all actuality, you might find a small speedup, but notice that you're wasting a portion of it waiting on mutual exclusio...

What is recursion and when should I use it?
...l solution is arrived at so we'll fast track and show each step on the way down:
return 5 * (4 * FactRec(3));
return 5 * (4 * (3 * FactRec(2)));
return 5 * (4 * (3 * (2 * FactRec(1))));
return 5 * (4 * (3 * (2 * (1))));
That final substitution happens when the base case is triggered. At this poin...
