2. Course Perspective This Course is Programmer-Centric
Purpose is to show how, by knowing more about the underlying system, one can be more effective as a programmer
Enable you to
Write programs that are more reliable and efficient
Incorporate features that require hooks into OS
E.g., concurrency, signal handlers
Not just a course for dedicated hackers
We bring out the hidden hacker in everyone
Cover material that you will not see elsewhere
