Processors, AI labs, and the first thing on SUN
Architected the Fairchild F9445, built systems for an AI laboratory, and put Smalltalk-80 on the prototype Stanford University Network workstation.
Selected work
A career spent changing layers.
The layer changes. The habit of looking underneath does not.
Making Smalltalk fast enough to become ordinary
Co-authored the POPL implementation paper and led the commercial system at ParcPlace. Dynamic translation and inline caching escaped into the world.
The Web, before the padlock icon
Co-designed Secure HTTP, led Secure Mosaic and the SET reference implementation, and helped early Internet credit-card transactions work in practice.
Three companies, three different kinds of problem
Founded Terisa Systems and Usable Security Systems; led product at CollabRx. Security, authentication, and personalized oncology.
Technical cases where the details are the case
Patent validity and infringement, licensing, copyright, antitrust, protected source code, and the history and architecture of commercial systems.
Tools for inconveniently large questions
Language models and conventional software for medical literature, patents, private collections, and code—reducing search spaces to reviewable evidence.
