Why study software foundations? � To prove specific properties of particular programs (i.e., program verification) ⊲ Important in some domains (safety-critical systems, hardware design, security protocols, inner loops of key algorithms, ...), but still quite difficult and expensive � To develop intuitions for informal reasoning about programs � To prove general facts about all the programs in a given programming language (e.g., safety or isolation properties) � To understand language features (and their interactions) deeply and develop principles for better language design (PL is the ”materials science” of computer science...) 4
What you can expect to get out of the course � A more sophisticated perspective on programs, programming languages, and the activity of programming ⊲ See programs and whole languages as formal, mathematical objects ⊲ Make and prove rigorous claims about them ⊲ Detailed knowledge of a variety of core language features � Deep intuitions about key language properties such as type safety � Powerful tools for language design, description, and analysis Most software designers are language designers! 5
