This is because most of the changes in the operating system maintain an unprecedented degree of backward compatibility.
In this chapter, we show you how to go about writing code, starting off with the simple “Hello world!” program. Then we move on to a desktop insulting machine and graphics modes, and end up mangling bits ...
