The Object-Oriented Analysis of Morse Code
to Text - John E. Harbold
John will present his very preliminary work (no PowerPoint slides), continuing
with the Morse Code theme from Forth Day. The problem of translating Morse Code
to text will be analyzed using the Executable UML method of Mellor &
Balcer. The problem will be broken into manageable objects and the
relationships between the individual objects. Objects can be passive or active.
Passive objects are those that just have data and methods that access them. On
the other hand, active objects have one state machine that responds to events.
Only analysis - no design or implementation - will be discussed.

Shannon Systems - Funds Transfer in
Forth - Larry Miller
In 1986 Shannon Systems was a start-up doing a dial-up modem secure (encrypted)
funds transfer system. This was a pretty ambitious project, and the software
was entirely Forth-based. Two "Famous Forthers", whom old-timers will
remember, Mitch Derick and Linda Baker, were major contributors to this
project. Larry will describe the system and show videos from "Completion
Day" and "Demo Day".
