RESUME/VITA

WORK HISTORY AFTER RETIREMENT

A very good use for crawlers loaded with extensibility is to make a focussed crawler which can quickly and efficiently build up collections of URLs of Web pages relevant to a given topic.

Five Cornell M. Eng. students in the Fall of 2002 put together a very respectible collection building system using a pluggable Web crawler, based on Mercator. My retirement project is to migrate that project from Mercator to Heritrix. If the project succeeds, then we will have a nascent collection synthesis system based on an open source Web crawler.

So far it is going well, and I am having lots of fun.

1982-1983: (on leave from Cornell) Senior Programmer at Intermetrics, Inc. Cambridge, MA. Helped implement semantic analysis phase of large optimizing compiler for a high-level language. IBM uniprocessors,  Sun Unix; PL/I.

1978-1981: Senior Computer Staff Specialist in the Scientific Support Group of Cornell Computer Services. Co-authored APTRAN, a Fortran compiler for the FPS AP-190L. This compiler was in use at Cornell from April 1978 until summer 1986. As of September 1980, managed  the Software Support Group, with responsibility for all applications software on Cornell's mainframe. IBM 360, FPS Array Processor, CMS, VM370; Fortran, APAL.

1971 to 1978: Lecturer, Instructor, and Assistant Professor in Mathematics at Ithaca College. Taught Fortran, PL/I, COBOL, Assembler, machine architecture, operating systems, data processing, and general computer science. Helped develop the computer science curriculum at Ithaca College. Directed several independent research projects.

1970 to 1971: Coordinator of Academic Computer Services, Ithaca College, Computer Center. Responsible for applications programming, systems programming, user documentation, and user services. Wrote batch monitor for running student jobs, wrote the student job accounting system, and wrote a load-and-go Fortran compiler. RCA Spectra; Assembler 360.

1969 to 1970: Systems Analyst for Tectonics, Inc., Ithaca NY. Wrote and maintained data processing programs for several construction firms; taught programming courses as required. IBM 1130; Fortran.

1968 to 1969: Systems Programmer, SUNY Computer Center, Buffalo NY. Interfaced CDC, IBM, and UNIVAC remote batch terminals with SUNY's CDC 6400 computer, which involved modification and testing of  software provided by various vendors, as well as dealing with communications hardware. The project,  a success,  was presented at the 1968 IFIPS Congress as one of the first experiments in university networking using multi-vendor hardware. CDC 6400; CDC Assembler.

1966 to 1967: Programmer Analyst for American Cyanamid, Bound Brook NJ. Worked on several scientific Fortran programs (simulations, gas chromatograph dye matching, real-time process control). IBM 1800; Fortran, Assembler.

1964 to 1966: Programmer for the Harvard Business School, Cambridge, Mass. and grader for Written Analysis of Cases. Maintained the Harvard Business School Game. IBM 7094; Fortran.
