Info on fixed point combinators. You can find a version that'll work with applicative order reduction here.
Halting Problem in Lambda Calculus/Scheme
Simple Scheme examples
more Simple Scheme examples
more interesting scheme code. (some code repeated)
Quicksort in Scheme
Graph search in Scheme
web server in Scheme. Here's the page it serves.
lists (updated) and trees in C. (use for comparison with scheme).
Scheme program written in class (reload for latest additions).
What language is this program in?

Perl Programs (supplement the Perl tutorial. Files in bold are required reading)

• Lambda calculus in Perl
• Static versus dynamic scoping
• Bank Accounts!! (oop with closures)
• OOP using packages and "bless" (new version)
• TCP client for downloading webpage
• CGI program for uploading files (source for above link)
• Binary data processing in Perl (not for the weak!)

Bank accounts in Scheme. (from 10/11 class).
More OOP examples: Rational number objects in Scheme, Perl, C++, Java, and C#, and for something really special: rationals in Eiffel : rational.e, rats.e. See compilation instructions in rats.e
Perl program from 10/13 class
Notes and thoughts on modeling oop in C. Please Read!

Static v.s. Dynamic dispatch in C#
Useful pointer casting in C, and what it could mean in C++
Delegates (higher-order functions) in C#
Three versions of polymorphic lists: polylist1.cs, polylist2.cs, polylist3.cs. They all use number.cs as a dll.

First AspectJ example. (Contains installation and compilation instructions).
Second AspectJ example superprivate.java and sptest.java
Aspect-oriented bank accounts: aopbank.java. Contains one of the problems of the programming assignment
More AspectJ Programs: advice precedence, preventing circularity, contro-flows, if pointcut, doubly linkedlist, pertarget aspects
