IBM 650 Emulator
This program emulates the base-10 IBM 650, publicly released in 1954 and support for the computer and its components was withdrawn in 1969. A description of the IBM 650, how it was designed, and how it interpreted commands can be found in this Topic Paper. A discussion of the design for the Python emulator can be found in this Topic Paper, and a discussion for the Scheme emulator can be found in this Topic Paper. The final report for the Python emulator can be found in this Topic Paper, and the final report for the Scheme emulator can be found in this Topic Paper. The way commands are interpreted by the IBM 650 is also discussed in detail in the comments in the initial lines of the source files.

Java vs. C++ Concurrency Benchmark
This project illustrates the use of concurrent programming practices in Java and C++ through the simple task of matrix multiplication. Using pthreads in C++ and the Thread object in Java, the coding shows the simplicity of concurrency in the languages and benchmarks the speed comparison. In summary, Java was much easier to implement and had a faster runtime than C++. A more detailed discussion of the design, implementation, and results from the benchmark can be found in this Topic Paper.

Sudoku Solver
This program will solve a Sudoku puzzle to any degree of difficulty received from an input file. The input file may be specified via an argument when launching the program, or if an argument is not specified the default filename “sudoku.txt” is used. This application solves using no efficiency algorithms, simply through brute force deduction. A discussion of the design, implementation, and testing of the Python Sudoku solver can be found in this Topic Paper.
