THE SECRET LIFE OF PROGRAMS - JONATHAN E STEINH...

A primer on the underlying technologies that allow computer programs to work. Covers topics
like computer hardware  combinatorial logic  sequential logic  computer architecture  computer
anatomy  and Input Output. Many coders are unfamiliar with the underlying technologies that
make their programs run. But why should you care when your code appears to work? Because you
want it to run well and not be riddled with hard-to-find bugs. You don't want to be in the news
because your code had a security problem. Lots of technical detail is available online but it's
not organized or collected into a convenient place. In The Secret Life of Programs  veteran
engineer Jonathan E. Steinhart explores--in depth--the foundational concepts that underlie the
machine. Subjects like computer hardware  how software behaves on hardware  as well as how
people have solved problems using technology over time. You'll learn: • How the real world is
converted into a form that computers understand  like bits  logic  numbers  text  and colors •
The fundamental building blocks that make up a computer including logic gates  adders  decoders
registers  and memory • Why designing programs to match computer hardware  especially memory 
improves performance • How programs are converted into machine language that computers
understand • How software building blocks are combined to create programs like web browsers •
Clever tricks for making programs more efficient  like loop invariance  strength reduction  and
recursive subdivision • The fundamentals of computer security and machine intelligence •
Project design  documentation  scheduling  portability  maintenance  and other practical
programming realities. Learn what really happens when your code runs on the machine and you'll
learn to craft better  more efficient code.
