Meeting Agenda for September
09:00 --- Halted / HSC Parking Lot Sale
members are encouraged to attend Halted's annual parking lot sale in Santa
Clara. There are always interesting things to see and purchase.
11:30 --- Lunch
We'll convene for
lunch up the street at St. John's Bar
and Grill on Lawrence Expressway.
12:45 --- Introductions, Announcements,
Rumors, and Random Access
At Stanford - Terman 556
13:00 --- eForth in C - CH
"I finally figured out how to force C to speak Forth. What I did
was first design a Forth virtual machine in C, which has 64 Forth primitives as
its machine instructions. While it was very easy to code this virtual machine,
it was difficult to implement a Forth dictionary structure that contained both
the primitive instructions as well as high level instructions. To get C to
construct this dictionary, I used my old eP32 metacompiler to build the
dictionary and shoved it down in the throat of the gcc compiler. I think this
is by far the simplest implementation of Forth in C ever."
14:30 --- Beagle Board - John
John will present a walk-through of the Beagle Board features. "I
will bring my Beagle Board on Saturday and show pieces of two videos. I will
also spend a few minutes talking about my desires for a Forth Integrated
Development Environment (IDE). I am just beginning to understand people's
discussion of Object Oriented (OO) Forth."
15:00 --- Ray-tracing in Forth -
Brad will demonstrate a ray-tracing renderer written in
Forth. Ray-tracing is a computer graphics technique for producing realistic
looking 3D images containing shadows, reflection, and refraction.
Traditionally, ray-tracers parse a scene description file, build up complex
data structures in memory, then traverse the scene graph while performing
floating point matrix calculations. In Forth these are replaced with: scene
description words, an executable scene graph, and fixed point vector
16:00 --- Adjourn
How you can help SVFIG:
- Bring your speaker and topic suggestions
to every meeting!
- Your input for and participation in next
year's Forth Day is always welcomed.
Coming to SVFIG in October
- Sam Falvo - "boring details of my
website's new blog implementation" - tentative
- Examples from the Forth Foundation
Library - John E. Harbold
John will demonstrate some code which
makes use of the Forth equivalent of a C++ Class Library. The
Forth Foundation Library (FFL) is a
general purpose Forth library whose main purpose is to make it easier to
develop applications. Examples to be presented will include using the Finite
State Machine (FSM) and Dynamic Strings.

Prototyping with QFP Parts -
This presentation will be based on an article in the
September 2008 issue of Circuit Cellar entitled "Prototyping with QFP
WAV File and Soundcard I/O Software
Using Win32Forth - Andy Korsak
This software was written for
amateur radio applications. Andy has suggested that it might be useful to look
at his code in advance of his talk. Contributions to this work-in-progress
would be welcomed. You can download and view his sound card software on the
group (membership required), or here.
Solicitations for presentations and
Mitch Bradley's Forth in C
volunteer is needed to present and demonstrate this software.
SVFIG is looking
for a volunteer to demonstrate PowerMOPS.
"The implementor of the PACE FIG-Forth responded to my email. I think he got
the idea that my invitation to present was 'one-time' rather than 'any time'.
Hopefully when there is something else PACE-related on the program, he'll join
us and present."
Meet the Mac - Kevin
Kevin Appert: "I'm having trouble emailing Ward McFarland, the
Carbon MacForth guy. If anybody knows a good way to buy a copy, please fill me
in! His email doesn't bounce, but he doesn't reply. The phone number is out of
service, but the website is still up. I'm also getting error boxes when I try
to start PowerMops under OS-9.1. I'd be grateful for any help."
