I am a computer scientist with approximately 30 years of programming
experience. My primary areas of expertise are in systems programming,
programming languages, software development tools, and software
engineering. Although I am most well known for my work in scientific
computing, I most enjoy working on problems related to the interface
between hardware and software. For example, operating systems, device
drivers, embedded systems, and programming tools.
I currently own and operate Dabeaz LLC, a consulting company that
primarily focuses on the development and use of open-source software
development tools. I am the creator of several well known programming
libraries and also offer professional training on the use of dynamic
programming languages such as Python. From time to time, I also offer
technical consulting related to software engineering, systems
analysis, and reverse engineering.
At Los Alamos National Laboratory, I developed applications
software, algorithms, and programming techniques for massively
parallel supercomputing systems including the Connection Machine 5 and
Cray T3D. In 1992, I was the primary developer and architect of SPaSM
(Scalable Parallel Short-range Molecular dynamics), a software package
for performing experiments in materials science (crack propagation,
fracture, dislocations, etc.). In 1993, SPaSM was one of the winners
of the IEEE Gordon Bell Prize competition in high performance
computing. In 1995, I helped pioneer the use of scripting languages
with parallel supercomputers and in 1996, I was the first developer to
port the Python programming language to such machines. The use of
scripting languages were an instrumental part of a massively parallel
data-analysis and data visualization system I built for remote
exploration of multi-gigabyte datasets. I presented this
work at a variety of international conferences including IEEE
Supercomputing, the International Parallel Processing Symposium
(IPPS), and the SIAM conference on parallel processing.
- Programming Language Interoperability
In 1996, I created a popular open source programming tool called SWIG
(Simplified Wrapper and Interface Generator) that automatically binds
existing C/C++ software to a wide variety of other programming
languages including Perl, Python, Tcl, Ruby, Java, C#, PHP, Scheme,
Ocaml, and many others. SWIG works by reading C++ header files and
automatically generating language bindings. To handle the complexities
of C++, SWIG implements the C++ type system and supports most language
features including templates, namespaces, and operator overloading.
SWIG has been downloaded by tens of thousands of programmers and is in
widespread use. For instance, SWIG is one of the core technologies
used to develop software at Google. It is also used by many government
laboratories including Los Alamos National Laboratory, Lawrence
Livermore National Laboratory, and Argonne National Laboratory. SWIG
is currently maintained by a team of developers from around the world.
More information is available at www.swig.org.
- Software Development Tools
In 2000, I
created a mixed-language debugging system called WAD (Wrapped Application Debugger), that allows
programmers to easily debug applications written in a mix of different
programming languages (e.g., C++ mixed with Python). WAD is unique
in its approach to this problem and a paper on the topic
was awarded "Best Paper" at the 9th International Python Conference.
In 2001, I created a Python implementation of the popular lex/yacc
parsing tools called PLY (Python Lex-Yacc). PLY is used by programmers to
implement parsers, interpreters, and compilers. In 2002, I released an embedded
webserver library that allows programmers to add web-based remote monitoring and
diagonistic features to C/C++ software. A paper on this library,
co-authored with Sotiria Lampoudi, won "Best Student Paper" at the 2002
USENIX Freenix conference.
- Computer Graphics and Data Visualization
I have written three separate graphics libraries. In 1986, I
developed a 3D mathematical plotting library (written in 6502
assembler) for the Apple 2. In 1990, I wrote a high-performance
graphics and animation library for the IBM PC. This library,
implemented entirely in 8086 assembly language, allowed programmers to
access SVGA graphics cards from programs written in the Modula-2
programming language. In 1995, I implemented a three-dimensional
graphics library and visualization system for massively parallel
supercomputers. This system allowed scientists to remotely analyze
large-scale data sets consisting of hundreds of gigabytes of data.
- Computer Architecture
I am familiar with the principles of computer hardware, systems design, and
low-level programming. I have written two major software packages
(graphics libraries) entirely in assembly language, both of which
directly controlled the underlying graphics hardware. On the
Connection Machine 5, I implemented numerical integration kernels in
assembly language in order to control special-purpose vector
co-processors. In a related project, I later showed that the
optimizations achieved using special purpose hardware (the vector
coprocessors) could also be achieved by carefully optimizing code for
the SPARC RISC processor instead. My work in compilers and debuggers
has also required a detailed knowledge of the underlying computer
architecture. Moreover, as a professor, I taught courses in operating system
design that focus on the connection between computer hardware and
systems software. As a graduate student, I was awarded the college of
engineering teaching award for my work as an assistant in the
undergraduate computer architecture and digital logic design courses.
- Computational Physics
At Los Alamos, I worked as a computer scientist in the Theoretical
Physics division and Center for Nonlinear Studies (CNLS). In this
position, I worked with physicists to develop software for solving a
variety of scientific problems. In 1991, I worked on software for
solving stochastic ordinary differential equations. This software was
used to study structural phase transitions in materials. In
1992, I started working on molecular dynamics simulation software. This
software was used to study problems in materials science including
fracture, crack propagation, and dislocation dynamics. Although my
primary focus was software, I was actively involved in all aspects of collaborative
research that led to publications in Science and Physical
- Book Author
In 1999, I wrote "The Python Essential Reference", a comprehensive
reference for the Python programming language. The Essential
Reference is one of the most highly regarded books on this topic and is
available in Japanese, Chinese, Russian, Polish, and German translation.
In 2001, I contributed three chapters on XML to the book "Python Web Programming" by Steve Holden.
A 3rd Edition of the "Python Essential Reference" was published in 2006. I am currently working
on the 4th Edition to be published in 2009.
- Software Analysis Consulting
Since 2003, I have occassionally worked as an independent technical
expert on legal cases involving copyrights and patents. This work has
involved a considerable amount of software analysis, including the
analysis of two large C++ systems each involving more than 500,000 lines of
source code. I have also analyzed more than a dozen smaller systems
involving source code for embedded devices and controllers. In the course
of my analysis work, I have been called upon to examine software written
over a 35-year time span. This software has been written in a variety
of programming languages including assembly language, Pascal, PL/M86,
C, C++, Visual Basic, and Java. In addition the software has involved
the use of custom-written operating systems as well as many
commercial systems including Windows-NT, Windows-CE, Linux, OS/2,
pSOS, QNX, iRMX, and AMX. In the course of analysis, I often must
deal with all aspects of the software from high-level distributed
systems (e.g., CORBA, COM) to direct control of specialized hardware
devices. A significant portion of my analysis work has also involved software
forensics. For example, matching undocumented software to specific versions of
hardware devices, uncovering technical specifications,
and working with software version histories.
- University Professor
At the University of Chicago, I was a tenure-track assistant professor where I taught graduate courses
in Operating Systems, Networks, and Compilers.
