Reticle Telescopic sights come with a variety of different reticlesranging from the traditional crosshairs to complex reticles designed to allow the shooter to estimate accurately the range to a target, to compensate for the bullet drop, and to compensate for the windage required due to crosswinds.
A secondary source of confusion is the fact that in "pass by reference", "reference" has a narrower meaning than the general term "reference" because the phrase predates it.
Now, the authentic definition is: When a parameter is passed by reference, the caller and the callee use the same variable for the parameter. If the callee modifies the parameter variable, the effect is visible to the caller's variable.

When a parameter is passed by value, the caller and callee have two independent variables with the same value. If the callee modifies the parameter variable, the effect is not visible to the caller.
Things to note in this definition are: This is now considered bad practice as an implicit dependency. As such, virtually all newer languages are exclusively, or almost exclusively pass-by-value.
The meaning of "reference" in "pass by reference". The difference with the general "reference" term is is that this "reference" is temporary and implicit. What the callee basically gets is a "variable" that is somehow "the same" as the original one.
How specifically this effect is achieved is irrelevant e.
Now, in modern languages, variables tend to be of "reference types" another concept invented later than "pass by reference" and inspired by iti. However, the net effect on the program can be the same as either pass-by-value or pass-by-reference: If a reference is just taken from a caller's variable and passed as an argument, this has the same effect as pass-by-reference: However, if a variable holding this reference is reassiged, it will stop pointing to that object, so any further operations on this variable will instead affect whatever it is pointing to now.
To have the same effect as pass-by-value, a copy of the object is made at some point. The caller can just make a private copy before the call and give the callee a reference to that instead.
In some languages, some object types are "immutable": So, passing an object of such a type as an argument always has the effect of pass-by-value: In functional languages, all objects are immutable. As you may see, this pair of techniques is almost the same as those in the definition, only with a level of indirection: There's no agreed-upon name for them, which leads to contorted explanations like "call by value where the value is a reference".
InBarbara Liskov suggested the term " call-by-object-sharing " or sometimes just "call-by-sharing" though it never quite caught on.
Moreover, neither of these phrases draws a parallel with the original pair. No wonder the old terms ended up being reused in the absense of anything better, leading to confusion.

Yiannis – Totally agree that there is a significant difference between strategic planning and project management. The nature and scope of strategic questions required to determine where to play and how to win are more expansive than tactical project questions.

Have you searched the web for IoC and AOP? There are a lot of references to both.. In a nutshell, IoC allows an external force to determine what implementation will be used by code rather than the code determining the implementation.
