It refers to Coach K being the all time winningest coach in men's college basketball history.

I know "A Simple Desultory Philippic" by Simon and Garfunkel, and "Mr. Jones and Me" by Counting Crows. But there are a couple others that elude me.

It is and counting, think of it this way. You are at said # and still counting, so 470 and counting, i.e. you are still counting there is more to be counted.

The king was in the counting house counting all his money.

Reference counting is a mechanism whereby a count is maintained for every reference to an object. When an object's reference count reaches zero, there are no references to it, so the object can be safely destroyed. References include pointers. They are used to ensure an object remains in scope for as long as there's at least one reference, and are used extensively in most garbage collection systems, which periodically destroys all objects that are no longer referenced.

High-level languages such as VB and Delphi have built-in support for reference counting, but C/C++ does not. The onus is therefore on the programmer to make consistent use of "smart" pointers, which simulate standard pointers but include additional information to aid with reference counts, memory management/ownership, and bounds checking.

When programming for a mixed-language environment, such as COM (component object model), where the individual components may be constructed from several sources written in different languages, and shared between different programs, maintaining accurate reference counts and reference ownership is essential to ensure no memory leaks occur. Microsoft have largely replaced COM with the .NET paradigm, so C#, F# and VB objects can safely co-exist, with automatic garbage collection, but the onus is still upon the C++ programmer to specifically code for the framework.
