Meeting Agenda for June
2009
10:00 --- Coffee and a Chat
10:15 --- Dissecting thisForth - CH
Ting
"I am trying to fully understand Wil Baden's thisForth to build
my eForth in C. It is a daunting task because thisForth uses the M4
macroprocessor to build its C program. I even called Wil and can report that he
is in good health at 81. I was able to delete all the optimization Wil put in
thisForth, and kept it working. I will discuss how thisForth was constructed
and some of its internal structures."
11:40 --- Lunch
Lunch on-campus.
To avoid the "noon lemming effect", we'll leave a little early.
12:30 --- Consensus-based Detour:
New Guinea Sculpture
Garden
On the way back from lunch we might detour to this
interesting collection. (If we decide to do this, add 12 minutes to the start
time of all items below.)
13:00 --- Introductions, Announcements,
Rumors, and Random Access
13:20 --- Rational Representation of the
Irrational - LaFarr Stuart
LaFarr will say something about a
couple different "words" that he thinks would be interesting in a
stack-oriented language and possibly a bit about finding best fractions such
as: 22/7 or 355/113 for Pi based on Continued Fractions (which involve pretty
complicated mathematical proofs; but there are relatively easy ways to use the
result, even with just a pencil and paper).
14:23 --- Break
14:32 --- Running FIG-Forth on Simulated
National Semiconductor PACE and IMP-16 Processors - Eric Smith
Eric will present further discussion and demonstration of FIG-Forth running on
a PACE simulator. Since last month, he's rewritten the simulator in C (it was
in Java before) and added a simulated disk. He has started work on converting
PACE FIG-Forth to an IMP-16 FIG-Forth with the eventual goal of running it on a
"real" IMP-16 system.
15:17 --- Photos from Maker Faire 2009
- Dave Jaffe
One hundred and nineteen images.
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:
-
Mitch Bradley's Forth in C - a
volunteer is needed to present and demonstrate this software
-
Update on IntellaSys Chips -
John Rible
The chips John Rible will be selling to SVFIG are being
tested now and perhaps he'll be at a future meeting to give us an
update.
-
Engineering TV
Fifty engineering
topic channels, four new episodes per week.
-
Botbash 2000 Video
A cheapie
video of a May 2000 robot rumble in Mesa, AZ.
-
PowerMOPS Demo
Looking for a
volunteer to present this.
-
Prototyping with QFP Parts -
Kevin Appert
This presentation will be based on an article in the
September 2008 issue of Circuit Cellar entitled "Prototyping with QFP
Parts".
-
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
Win32Forth
group (membership required), or here.
