4 DAYS AWAY!
--- SVFIG Meeting September 26, 2009 ---
AM - Sunnyvale at HSC
PM - Palo Alto at Stanford
Please note that the times listed below are precise but not
accurate. We might go a little long or short on any agenda
item. If you're desperate to see something at a particular
time, please let us know! Remember that there are bugs in
any non-trivial SVFIG meeting announcement.
We'll be on the fifth floor of Terman Engineering Center --- Room 556
Directions and map links are below.
There are two buildings named Terman on campus so be careful. The
Searchable Map has the one you want as "TERMAN (FREDERICK E) ENGRG
CENTER (04-700) 380 PANAMA MALL"
The Official SVFIG Announcement Editor's Parking Lot recommendation is
the lot near the intersection of Teresa St and Morris Way.
09:00 --- Halted / HSC Parking Lot Sale
SVFIG 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
12:45 --- Introductions, Announcements, Rumors, and Random Access
At Stanford - Terman 556
13:00 --- eFORTH IN C - CH Ting
"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. I had trouble getting C to construct this dictionary, so 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 Slater
"I will bring my Beagle Board on Saturday and show pieces of 2 videos.
I should not take more than 20 minutes. I will also spend a few minutes
talking about my desires for a Forth IDE. I am just starting to be able
to understand people's discussion of OO Forth. I hope other people are
able to learn and understand Forth more easily than me."
15:00 --- RAY TRACING IN FORTH - Brad Nelson
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 operations.
16:00 --- Adjourn
The schedule above may be reformatted or line-justified but
please transmit verbatim or not at all. Any font you like is
alright with me.
No Newsgroup posts or other media distribution this month please!
Wireless Internet access is anticipated (though not guaranteed) at
Stanford, so bring your wifi-enabled laptop.
Coming to SVFIG:
* Bring speaker suggestions TO EVERY MEETING!
* PLANNING FORTH DAY 2009 - EVERY MEETING
* Mitch Bradley's Forth in C (somebody needs to volunteer)
* I've sent an email to the implementer of the PACE FIG-Forth and he
responded. 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.
* Furthering the Cause of Forth - John Rible
IntellaSys has imploded, or something. We'd be pleased to hear about
John's new outreach project when formulated.
* Engineering TV
Fifty engineering topic channels. Four new episodes per week.
* BOTBASH 2000 --- Video
A cheepie video of a May 2000 robot rumble in Mesa Arizona from these
* Meet the Mac --- Kevin Appert
I'm having trouble emailing Ward McFarland, the Carbon MacForth guy. If
anybody knows a good way to buy a copy, fill me in! The email doesn't
bounce but it doesn't get answered. The phone number is out of service
but the web site is still up.
I'm also getting error boxes when I try to start PowerMops under OS-9.1,
so if anybody wants to help out there I'd be grateful.

Terman Engineering Center can be found on these maps - just search for
Terman: (going to maps.google.com gives an erroneous result)
Searchable Stanford Campus Map: http://ucomm.stanford.edu/cgi-bin/map/
There is open parking on weekends. Park in any A or C or metered space,
no coins needed even if there's a meter there.The Official SVFIG
Announcement Editor's Parking Lot recommendation is the lot near the
intersection of Teresa St and Morris Way.
Go to the Stanford links, Google maps has no idea where Terman is!
The building's door may be locked, there will be a number to call posted
after the meeting starts and we will come down and check once in a while.
Once you reach Terman, take the elevator to the 5th floor. Walk across
the foyer and up the ramp just to the left of the glassed-in office.
Room 556 is at the top of the ramp - entrance on the left.
