David Woodruff, a professor in CMU's Computer Science Department, and Samson Zhou from Texas A&M University received a ...

The control structures that test Boolean values only test for whether or not the value is nil, which is considered to be false. Any other value is considered to be true. Often a predicate will return ...

PREFACE: The language defined by the first edition contained an enormous lacuna: although facilities were specified for signaling errors, no means was defined for handling errors. This occurred not ...

This course covers the design and implementation of compiler and runtime systems for high-level languages, and examines the interaction between language design, compiler design, and runtime ...

Carnegie Mellon is known for its stressful environment, and we realize that the pace and expectations of 15-213/15-513/14-513 can contribute to that stress. If you find yourself having trouble keeping ...

The do special form provides a generalized iteration facility, with an arbitrary number of ``index variables.'' These variables are bound within the iteration and stepped in parallel in specified ways ...

If the :constructor option is given as (:constructor name arglist), then instead of making a keyword-driven constructor function, defstruct defines a ``positional'' constructor function, taking ...

Create your own election scenario! In this map, the states are sized in proportion to their Electoral College vote for president. Instructions: Click or double-click on any state to swing that state's ...

I am a software engineer on the Tools and Simulation team at Pixar. I completed my PhD in 2021 at CMU's Computer Science Department, with Keenan Crane as my advisor. These publications emerged in part ...

For now, we will not be using the main OH queue until it stabilizes a bit. We hope to use it again later this semester.
