Better Behavior in Object-Oriented Programming ==================================== I used to have no interest in software security, and even to disdain it as a pedantic and non-creative area. I have recently reversed this position, and I would like to share my new-found enthusiasm for security in OOP. My feeling is that a tasteful combination of good formal techniques and a Squeak-like kernel could bring simplicity and flexibility to robust system design, and many desirable properties to Squeak and malleable systems like it. Using this single thread (and I am trying to think of a better word than "security"), I hope to tie together issues of type specification, mutability, change management, multiprocessing and distributed computing.

Bio == Dan Ingalls has been the principal architect of five generations of Smalltalk environments. He designed the byte-coded virtual machine that made Smalltalk practical in 1976. He also invented BitBlt, the general-purpose graphical operation that underlies most bitmap graphics systems today, as well as pop-up menus. He has received the ACM Grace Hopper Award for Outstanding Young Scientist, and the ACM Software Systems Award.

Dan's major contributions to the Squeak system include the original conception of a Smalltalk written in itself and made portable and efficient by a Smalltalk-to-C translator. He also designed the generalizations of BitBlt to arbitrary color depth, with built-in scaling, rotation, and anti-aliasing. Dan leads the external Squeak community through active participation in e-mail discussions, and attention to regular releases and reasonable support.

Dan Received his B.A. in Physics from Harvard University, and his M.S. in Electrical Engineering from Stanford University. While working toward a PhD at Stanford, he started a company to sell a software measurement invention that he perfected. As the challenges and rewards of industry have continued to hold his interest, he never returned to academia.
