This presentation describes how to build a very efficient framework to manage client-side object-level transactions in a two-tiered, wide-area network environment. This framework was built and depolyed for a large-scale information management application. The server described is built using built using the GemStone object database, and the clients are written in VisualAge/Smalltalk.

This talk explains the fundamentals of building real-time 3D video games. It explores the game development pipeline, the tools we developed to manage artistic resources, and looks at some fundamental 3D data structures and algorithms.

We expect and have far less privacy online than we do in the physical world. This talk is about building tools to raise our level of online privacy. It explores options for securing information locally, and information that is sent over email, and finally discusses building a protocol to chat over the MSN instant messenger network in a cryptographically secure way.

These notes are a distillation of several years of refactoring experience. They talk about the various levels of refactoring, and explains how to approach - and complete - the clean up task.
