How do you implement a Stack and a Queue in JavaScript?
...have a really good reason for it... while it might seem logically correct, CPUs don't operate according to human abstractions. Iterating over a datastructure that has pointers all over the place will result in cache misses in the CPU, unlike a sequential array which is highly efficient. blog.davidec...
Should I use char** argv or char* argv[]?
... says: argv is a non-null pointer pointing to at least 5 char*'s
// allows CPU to pre-load some memory.
int main(int c, char *argv[static 5]);
// says: argv is a constant pointer pointing to a char*
int main(int c, char *argv[const]);
// says the same as the previous one
int main(int c, char ** c...
Why doesn't .NET/C# optimize for tail-call recursion?
...what I know.
Sometimes tailcall is a performance win-win. It can save CPU. jmp is
cheaper than call/ret It can save stack. Touching less stack makes for
better locality.
Sometimes tailcall is a performance loss, stack win.
The CLR has a complex mechanism in which to pass more paramet...

Is there a way to access an iteration-counter in Java's for-each loop?
... invoke constructor, scan sooner with GC and finalize. This not only loads CPU but also invalidates the cache all the time. Nothing like this is necessary for local variables. Why do you say that this is "the same"?

When do I really need to use atomic instead of bool? [duplicate]
...will work in a similar way for bool and atomic<bool>. But multi-core CPU and missed memory barrier is something that will happen with nearly 100% chance for any modern application and hardware

WPF TemplateBinding vs RelativeSource TemplatedParent
...elative since the binding operation takes very little of the application's cpu. If you were blasting control templates around at high speed you might notice it.
As a matter of practice use the TemplateBinding when you can but don't fear the Binding.
