- Read carefully the documentation page of the sync package that can be found at https://golang.org/pkg/sync/.
- Try to implement dWC.go using a different shared memory technique than the one used in this chapter.
- Implement a struct data type that holds your account balance and make functions that read the amount of money you have and make changes to the money. Create an implementation that uses sync.RWMutex and another one that uses sync.Mutex.
- What would happen to mutexRW.go if you used Lock() and Unlock() everywhere instead of RLock() and RUnlock()?
- Try to implement traverse.go from Chapter 5, Files and Directories using goroutines.
- Try to create an implementation of improvedFind.go from Chapter 5, Files and Directories using goroutines.

Overview of this book
Go is the new systems programming language for Linux and Unix systems. It is also the language in which some of the most prominent cloud-level systems have been written, such as Docker. Where C programmers used to rule, Go programmers are in demand to write highly optimized systems programming code.
Created by some of the original designers of C and Unix, Go expands the systems programmers toolkit and adds a mature, clear programming language. Traditional system applications become easier to write since pointers are not relevant and garbage collection has taken away the most problematic area for low-level systems code: memory management.
This book opens up the world of high-performance Unix system applications to the beginning Go programmer. It does not get stuck on single systems or even system types, but tries to expand the original teachings from Unix system level programming to all types of servers, the cloud, and the web.
