Network game analyzer: research project overseen by Evi Nemeth; analyzed CAIDA coral traces to determine workload characteristics and performance of network game traffic over the Internet (Perl/C/libpcap/bpf).
Pre-emptive threads package: provided prioritized and round-robin processor scheduling, condition time-outs, and asynchronous I/O. Worked within a team of three by modularizing tasks and maintaining a consistent API.
Research project overseen by Dr. Scott Baden; evaluated the Message Passing Interface (MPI) and Bulk Synchronous Parallel (BSP) APIs using several nodes of an SGI Cray Origin2000 located at NCSA.
SPARC/Solaris RPCd buffer overflow: successfully exploited an unbounded memory copy in a RPC client/server package by overflowing the remote stack and overwriting a function return pointer to redirect its flow of execution to the injected code (C/gdb/asm/truss).
