Go Systems Programming

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.

Exercises

  1. Visit the documentation of the runtime package.
  2. Create your own structure, make a slice and use the sort.Slice() to sort the elements of the slice you created.
  3. Implement the quicksort algorithm in Go and sort some randomly-generated numeric data.
  4. Implement a doubly linked list.
  5. The implementation of tree.go is far from complete! Try to implement a function that checks whether a value can be found in the tree and another function that allows you to delete a tree node.
  6. Similarly, the implementation of the linkedList.go file is also incomplete. Try to implement a function for deleting a node and another one for inserting a node somewhere inside the linked list.
  7. Once again, the hash table implementation of hash.go is incomplete as it allows duplicate entries. So, implement a function that searches the hash table for a key before inserting it.
