Who I am

I am a software developer and author of computer books. I also work on some problems in theoretical physics. This is my personal Web site where I publish information about:

• My work, programming in C/C++ and other languages, for Windows, Linux, and other operating systems,
• The books I wrote, about C++, Linux, and more,
• My physics papers and notes,
• My Web site featuring my multimodal AI chatbot, my custom transformer and other machine learning projects,
• My Web site dedicated to vintage programmable calculators,
• The world's first Multi-User Dungeon, which I ported from BCPL to modern platforms and still maintain,
• My knowledge base of diverse technical notes, including notes on AI and machine learning
• And links to other sites, including Web sites of my own.

My professional experience

I received my first software development contract in 1979: My task was to simulate the take-off distance of TU-154 aircraft with engine failure at Budapest airport under various weather conditions, to compute tables of maximum take-off weight. Since then, I worked on many software projects and I am thoroughly familiar with the entire software development life cycle. I authored or co-authored studies for large software projects: For instance, I was one of the authors of the $65M Automation Master Plan of the Canadian Patent Office in 1988. I designed and developed the Windows version of Industry Canada's Integrated Spectrum Observation Centre, with over 120,000 lines of C++ code. I created NORTEC's HELP (Humidification, Engineering and Loadsizing Program), an application for professional engineers and salespersons dealing with large-scale building humidification systems. I also wrote several books on the C++ programming language and the Linux operating system. As part of my scientific research, I independently developed a precision orbit determination program used to analyze the anomalous trajectory of the Pioneer 10 and 11 spacecraft. More recently, I worked under contract with NASA JPL on the Solar Gravitational Lens, investigating the possibility of using gravitational lensing by the Sun to image distant targets, including possible life-bearing exoplanets. I am also one of the maintainers of Maxima, the preeminent open source computer algebra system.

I am just as competent with modern software development technologies as with ancient systems. I routinely switch between developing an interactive app for my Android smartphone and maintaining 50-year old legacy LISP code for Maxima. I am familiar with formal software project management and development methodologies. Last but not least, I also have experience designing and debugging hardware.
