In Praise of Language Specs

Posted by cayhorstmann on June 27, 2011 at 7:25 AM PDT

I give an example of why having a language spec builds confidence in a situation that would induce fear and trembling in a seat-of-the-pants programming language. I boldly generalize to posit that it is good to have multiple implementations of a spec, and that there should be more than one implementation of the Java platform. ♦

There Will Be Monads

I finished my "modern programming languages" course at the Ho Chi Minh City University of Technology. We covered metaprogramming (with Ruby and Rails), continuations (with Racket and Scala), concurrency (with Scala and Clojure), and finished off with a dose of Haskell to see type inference and type classes in action. Here are the hardy souls who stuck it out until the end.

I cleaned them up and translated them into Scala because that's what we use in the course. Here they are, for your puzzling pleasure.

Having a Racket with Pictures and Continuations

Posted by cayhorstmann on March 22, 2011 at 8:50 PM PDT

In this blog, I describe how the Racket language provides fun graphics and a nifty web framework. The  former is great for beginning students, and the latter is helpful for grasping the mind-bending concept of continuations. ♦
