Resolve build errors due to circular dependency amongst classes
...ember that the .cc and not the .h is the unit of compilation), you need to allocate space for object A. So, well, how much space then? Enough to store B! What's the size of B then? Enough to store A! Oops.
Clearly a circular reference that you must break.
You can break it by allowing the compiler ...
Executors.newCachedThreadPool() versus Executors.newFixedThreadPool()
...terminated. So the pool can shrink if threads remain too much idle.
If all allocated threads are occupied while a new task comes in, then it creates a new thread, as offering a new task to a SynchronousQueue always fails when there is no one on the other end to accept it!

When to use inline function and when not to use it?
...iron reason to avoid inlining a function. The implementation is obliged to allocate a single static object for each function static whether or not the function is declared inline or not. Classes are still extensible if they have inline constructors and virtual destructors. And empty brace destructor...
