From the lead author: (1) The book is not finished yet. But it will appear with MIT Press, and I expect it to appear over the next year and a half or so. (2)

From the lead author: (1) The book is not finished yet. But it will appear with MIT Press, and I expect it to appear over the next year and a half or so. (2) Realm is best read after HtDP [1e or 2e] or some other course on plain programming (not necessarily program design). It teaches (simple) programming in Racket. (3) HtDP [2e] does NOT teach programming in Racket. It uses several teaching languages, each matching a stage in the convex hull of the design recipes (tactics) of a certain part of the book. HtDP's design tactics do away with the usual "everything is a Turing machine so learn by coping me" approach.
