This course is an accelerated introduction to college-level computer science. Our AFQ explains how you get into the course.
In this course, we’ll be using a programming language called Pyret, in which we will practice functional programming. (We don’t assume you know anything about either, and will teach you both from scratch.) We will actually use only a tiny sliver of Pyret, not exposing you—much as we’d love to!—to its many powerful features, because this isn’t a course about Pyret. Rather, it’s a course about software construction, which means: being able to design programs, and being able to translate designs into implementations. Designing software means making wise choices about data structures, algorithms, and program organization. Implementing means more than just writing code: it means making wise decisions about systems and interfaces.
Every reader should ask himself periodically “Toward what end, toward what end?” —
but do not ask it too often lest you pass up the fun of programming for the constipation of bittersweet philosophy.
