Description

Programming language design as exemplified by Scala, a new type-safe language that combines functional and object-oriented aspects at the language level and targets the Java Virtual Machine. Scala's type inference system and the promise of "scalable component abstractions" for software systems. Applications to concurrent programming and domain specific languages. Weekly readings. There will be 4-7 mandatory assignments.

Please note that this is a Student Initiated course so is classified as an "activity unit" and will not satisfy degree requirements.

Prerequisites

Academic exposure to at least two programming languages; CS107 recommended.

Grading policy

The course is graded on a C/NC basis only. To receive a passing grade, you must complete all but one of the weekly assignments and participate actively in class.

The course description on Axess incorrectly states that weekly assignments are optional and that there is a mandatory final project. There will be no final project. Weekly assignments are mandatory.

Collaboration policy

You are encouraged to discuss their ideas with others. However, you should work on your programs independently and hand in original code. If you receive significant help from others, you should attribute them when handing in your assignments.

Class Mailing List

Signing up for the class on Axess will automatically subscribe you to the class mailing list. Please make sure to do so as soon as possible.

Auditors

Auditors are welcome, but please make sure to sign up for the class mailing list manually by visiting: https://mailman.stanford.edu/mailman/listinfo/cs94si-spr0708-students

Scala Version

The class will use the Scala 2.7.0-final release of the language. It can be obtained from: http://www.scala-lang.org/ Instructions on how to install Scala will be included in the first assignment.

"Scala lift off" Conference

On Saturday, May 10th a Scala/lift conference will be held in San Francisco. The conference is free for students (free lunch is provided). This is a fantastic opportunity to meet many of the people in the Scala and lift communities, including Prof. Martin Odersky. Please register for the conference at: http://scalaliftoff.com/liftoff/
