• Java/Scheme Interface, for creating a dual-language system. Logically, Java keeps track of objects and data, and Scheme tracks operations and decisions (possibly with a codelet system). Here is the Java Code and the Scheme Code.
• Short Scheme Introduction and Continuation.
• Example of Current Continuations. I don't remember testing this.
• Bit Code Examples:
  Bit Code is an attempt to make a Turning Complete language with minimal commands; in fact, only two: one to increment a number pointed to by a data address, and one to load a new value into the data address. For added cleverness, the data pointed to by the data address is used as the pointer to the next command, so that incrementing this number also moves on to the next command. I have a C program for generating and running random strings of bits and a GIF and FIG graphics that explain how the syntax works.

• Java/Scheme Interface, for creating a dual-language system. Logically, Java keeps track of objects and data, and Scheme tracks operations and decisions (possibly with a codelet system). Here is the Java Code and the Scheme Code.
• Simple, interactive game of life (cellular automata) to practice using Java Swing classes. Zipped java files.
• "Measure" class which handles physical dimensions (mass, distance, time) and a 3-D "Vector" class that uses it, for building physical systems in a structured, error-checking way. Unsure status. Contained in Zip file.
• Partially constructed "ClockMaker" system for allowing students to construct and simulate clocks and other physical systems using a combination of physical abstractions and collision-dection mechanisms.
• Collection of words from Aesop's Fables (does not include all stories), formated for use in C or Java.
• Scheme Code to generate J-SIM circuit commands (similar to PSPICE) without efficiency-wasting abstractions. As the example, a recursive, abstraction-rich definition of an adder can be converted to an abstraction-less definition with the Scheme Program which keeps tracks of the inner workings of all abstractions.
• Beginning of a optimization system for circuits, capable of breaking down abstraction barriers like consistent stages in a calculation to gain speed. Scheme code which generated (I think) a ton of connections for a 32 bit adder.
• Beginning of a genetic algorithm for creating map-solving "roboants": the incomplete code and an example roboant
• 3-D Differential Equation Programming System, allowing one to state interrelated equations in programs and use their solutions. Final project for C++ class (buggy?).
• Beginning of a Inter-language communicator, written in scheme.
• Scheme-Based Histogram Abstraction and functions. Histogram Object, Histogram Statistics, Histogram Distance Calculation; I don't remember what here is fully tested.
• Scheme/C Interface, for creating a dual-language system. Based on my system for the ZephyrManager. C performs interfacing to the outside world, but the main brains of the program are left to Scheme. Scheme-Side Driver, Main Scheme Loop, C-side commands; this is a possibly-non-working adaptation of a previously working system.
• Scheme code to convert an HTML page to a structured tree (tagged lists within tagged lists). Adaptation of a usually-working system (confused by some bad HTML) that I made in 6.001. Possibly equivalent to this Perl code.
• Fast Convolution C Code, using an overlapping FFT block method. Includes both Pentium optimized assembly code and a comparison C program which uses FFTW.
• C Symbol conversion utility, which I made to allow a single program to include FFTW in both single and double precision modes. Replaces all symbols in a list of C files with names that include a prefix. Could be widely useful, but documentation is thin. You can see the fftw command I used.
