IntraNetworking Systems (formerly Ascend Communications)
- Optimized (both for machines & humans) development environment
for TAOS software. Developed scores of reusable Perl modules for
simplifing SQL queries, cross-referencing code, and many standard
tasks. Integrated many unnecessarily-separate web pages, lots of CGI,
||May 1998-Jan 2001
- Designed and developed software for analyzing data from
Deep Space One,
space exploration missions. Updated and/or rewrote thousands of lines
of scientific software in order to make portable and add features.
Automated all processing of incoming telemetry and data. Work which
was formerly done daily by people, is now done nightly without
Designed informative, visually pleasing, easy-to-read plots
of instrument data, and developed software to generate
these automatically. Developed simple graphical interfaces
to these routines, in order to allow Investigators
to view results online in real-time.
Developed efficient, automated WWW interfaces to
supply mission data to worldwide
scientific community. Investigated algorithms
for generating useful information from raw data.
Evaluated spacecraft health telemetry and designed
methods for flagging ``suspect'' data.
Wrote code for performing statistical analyses of the solar wind.
Wrote hundreds of IDL procedures to generate daily summary plots
for new data, as well as special-case plots for publication or
Developed core set of reusable modules used across most instruments.
Developed a clean, elegant
to the UDF data format library, allowing
dozens of scientists on the IMAGE mission to access their data
with ease. My code provides a simple Open/Read/Close interface
to the complicated underlying UDF mechanisms.
- Developed a simple-to-use library for performing
transformations between physical frames of reference. Surprisingly,
although these transformations are used daily in solar plasma
physics, no comprehensive library existed for this purpose.
system for interfacing IDL to SPICE (a JPL toolkit for providing
spacecraft ephemeris). My system comprises a Perl script that reads
in a well-formed .h file with function prototypes, and
generates wrappers and housekeeping code for nearly 300 functions.
JPL will be shipping my system with their next release of SPICE.
Was primarily responsible for the maintenance and administration of a
Convex C3240 system controlling a Metrum RSS600 tape jukebox. This
required constant monitoring of tapes, tape drives, the robot, and
(not least) the FileServ software that runs it. It also required
me to educate users in the best ways of storing and accessing
their data on this mass storage system. Developed
dozens of tools to assist in its regular maintenance and auditing.
Was also responsible for the
operation of over one hundred mixed UNIX workstations spread out over
three physical networks. This entailed
all aspects of their running, from the initial installation
to their everyday successful operation. To aid in this, I
developed yet more tools for handling such things as backups,
host table generation and checking (e.g., to keep the central DNS
registry up to date), new account and mail alias generation,
automount map creation, disk space monitoring,
and all the typical duties of your standard sysadmin.
One of my more successful developments has been the
hieararchy for software packages.
The UNIX "cluster" is served by two
Network Appliance F330 servers,
which require so little administration that it's almost embarassing
to claim expertise on them. I have implemented a reliable
for them as well as a proactive disk quota system for preventing
inadvertent disk overruns.
Was also webmaster at
created a large number of
there as well as some for internal HP-Convex servers. All my
documentation on the
running of the UNIX cluster is online there as well.
From December 1997 through May 1998, worked in NIS-1 as scientific
programmer (see above). Same job as today, just subcontracting differences.
||March 1992-June 1994
|Software Engineering group, Santa Clara, CA
Working in a team of four, ported the Auspex NetServer software to an
AIX platform. This included all levels, from close to a hundred shell
scripts and user applications, to a handful of device drivers. This
project required much design work to integrate the Auspex software
into the AIX environment in a clean manner. Moved source base for
this project from RCS to
control and wrote scripts to assist in
source code control and management.
Wrote driver code used in bringup of new multifunction
I/O processor board. This included integrating OpenBoot
principles into the Auspex (Sun-based, not AIX) kernel.
Developed and maintained internal bug-tracking tool used
hundreds of times each day to manage bugs and RFEs. Wrote e-mail and CGI
front ends granting customers visibility into selected portion of
When the company moved to a new, much larger building, wrote a
application used for finding peoples' new offices.
Prototyped, set up and
implemented WWW server for Auspex, including customer access to
company information, press releases and selected bug information.
For over a year, my work remained Auspex's principal web presence.
Investigated and recommended third-party alternatives for source
control, bug tracking, and layered product packaging.
||May 1988-March 1992
|Workstations Systems Engineering group, Palo Alto, CA
Designed, specified and prototyped "windowing ROM" environment for
Designed and implemented set of tools for managing
hardware design releases. This involved interfacing between two
disjoint groups--Design Engineering and Manufacturing--neither of
which really understood what the other did. My job was to understand
both sides and create an automated solution.
Ported parts of OSF/1
kernel to new hardware platform of DECstation 5000 line.
Wrote dozens of task-automating tools for coworkers
throughout the site. Wrote tools to manage my workstation, and
acted as local Ultrix contact and support-type for our group
after we "withdrew" from site-wide system management.
I even did some hardware! Designed keyboard interface board using
I²C protocol. Enhanced and fixed several in-house CAD packages in
Designed diagnostic strategy and architecture for DECstation 5000 line.
Implemented diagnostic suite for CPU subsystem. Wrote TURBOchannel
diagnostic architecture specification. Developed tools to provide
simple and powerful development environment for TURBOchannel option
board firmware developers (both in-house and third-party).
Developed firmware and loadable CPU, cache, memory and I/O diagnostics for
multiprocessor VAX workstation. Developed network subsystem
diagnostics for DECstation 3100 (DEC's entry into the RISC market).
||May 1987-May 1988
|LES Diagnostic Engineering group, Maynard, MA
Developed CPU and network diagnostics for MicroVAX 3000 systems.
Assisted in initial debug of CVAX processor chip. Wrote tools to
simplify and automate diagnostic development.
Worked on Advanced
Development project involving automated interpretation of diagnostic
error messages using a windowing interface. Set up and managed local
area VAXcluster of workstations for development group.
|Software Engineer (co-op)
|Hudson Computer Resources group, Hudson, MA
Assisted in system management of Hudson's VMS computer facilities. Wrote
tools to make life simple. In spare time, set up tool suite for
Training group and built simple environment to help in managing
distribution lists and technical seminar mailings.
|Software Engineer (co-op)
||Summers 1984, 1985
|TOPS-20 OS Monitor group, Marlboro, MA
Worked on enhancements for TOPS-20 release 6.0 and 6.1. Fixed bugs
and tested code for previous releases.
Knowledgeable (user & kernel level) in several flavours of UNIX
(Linux, *BSD, Solaris, HP-UX, Ultrix, OSF/1), VAX/VMS and
TOPS-20 operating systems. Fluent in
HTTP/HTML/CGI environment. Have
done some X11 programming, but not recently (e.g., see
xlbiff in X11R6 contrib tape).
Fluent in C, Perl, IDL, PostScript, sh, and the like.
Once fluent in C++, MIPS assembly, VAX macro, MACRO-20,
Forth, Lisp, 6502 assembly, awk/lex/yacc/etc.
If pressed, will admit to having coded in Pascal, FORTRAN, APL and
3081 assembly. Conversant in java.
Fluent in English and Spanish. Conversant in ASL (American Sign
Language). Now trying to learn Russian. In the process of
forgetting my German.
