We will travel through a retrospective overview of some of the great "hurdles" in the area of Memory Management, from the discovery of "Garbage Collection", through the realization of the potential harmfulness of GC, to the expanded horizons which are driven by paradigm shifts in application programs. In the process, we will review some of the very early approaches to memory management to appreciate just how far we have come, and just how much the great leaps of this science have been driven by the appearance of cheaper and faster hardware. We will also re-visit some "war stories" of the past where a paradigm shift was forced because of unforseen consequences in what was otherwise perceived to be a "Very Good Idea(tm)". Examples will include the speaker's own pioneering experiences in shifting from pure "collection" techniques to BIBOP storage strategies, compile-time change-of-representation for a one to two orders of magnitude speedup in numerical programs written in Lisp, to the discovery of the "Pig-in-a-Python" syndrome. Speculative, overview-like conjectures will be made about the current horizons of the field, especially with respect to large databases and the Java programming language.
JonL received a B.S. degree in Mathematics from Carnegie-Mellon University, and an M.A. in Applied Mathematics from Harvard University. He subsequently joined Marvin Minsky's team at the M.I.T Artifical Intelligence Laboratory, where he began the development of high-quality Lisp systems and compilers. The PDP10 MacLisp efforts subsequently supported not only the A.I. lab, but the MACSYMA Symbolic Algebra group, and ultimately many other university and commercial research labs. JonL also spent one calendar year away from MIT at IBM's Watson Research Center in Yorktown Heights, NY, contributing to the development of Lisp/370.
At the birth of the commercial A.I. revolution, JonL joined a group at Xerox's Palo Alto Research Center tasked with product development of Interlisp on the special-purpose, microded Xerox D-series machines. A few years later, in January 1985, he joined the "startup" company Lucid, Inc. whose goal was to make high-quality Common Lisp systems available on all the prevalent "stock" hardware machines. As the commercial A.I. market - and consequently the commercial Common Lisp market - went into decline in the early 1990's, JonL joined the Lisp group at Harlequin. In all of these commercial Lisp developments, JonL contributed substantially not only to the compiler development, but also to both "GC" and higher-level memory management.
After a brief 8 months at NASA/Ames Research Center working with the Automated Software Engineering group there, JonL joined yet another startup - a spin-off from Stanford University - which was quickly bought out by his present employer CommerceOne. He is currently working on a product called iMerge, written in Lisp and a result of many years of A.I. research at Stanford which is directed at the database needs of today's Business-to-Business commercial environment.
