Senior Programmer
-
Solely responsible for Motif port (in C++) of
SoftQuad Panorama, an SGML viewer.
- Designed and wrote a complete HTTP 1.0 implementation for it from scratch
- Technical liaison with third party technology provider. Provided design assistance and initial MS-Windows porting work
- Subsequently rewrote it to be a Unix Netscape Plugin
-
Responsible for a large-document fragmenter/CGI-retriever suite (C++),
which worked in conjunction with Panorama to let one
efficiently view arbitrarily large SGML documents.
-
Co-designed and implemented the PSI Portable Scheme Interpreter,
an
R4RS compliant
implementation of the Scheme Programming Language, designed to be portable from anything from
MSDOS to MS-Windows to Unix.
-
Designed and implemented PSIOOP, an efficient object-oriented
language extension with first-class objects for PSI written in C.
-
Integrated the PSI Scheme interpreter into
SoftQuad Author/Editor (an SGML editor)
allowing C++ classes to be treated as Scheme classes and vice-versa.
This system became the core of
SoftQuad Sculptor,
a script-customizable SGML editor. This in turn is what was used to develop
SoftQuad HoTMetaL 1.0,
the world's first HTML editor and
SoftQuad Apex,
a specialized tool for editing electronics spec sheets.
