Bach Cantatas - CH Ting "Currently I am making
videos of my most favorite cantatas. I have completed the entire BWV51 'Shout
to God, all the earth' and two most popular chorals: 'Jesu, Joy of man's
desiring' and 'Sheep may safely graze'." |

DCW (Digital Chart of the World) Update - CH
Ting "I've re-worked the Digital Chart of the World code so that it does
not crash, and it runs faster. Since I have 4 GB of RAM on my PC, I thought I
could load the entire 1.8 GB map data file into RAM and then I would not have
to read from the data file anymore. It turned out that Windows 7 only allocates
1.5 GB to my F# system. If I ignore Antarctica, 1.5 GB is enough for the rest
of the world. The software is now working smoothly. The initial reading of the
data file takes 15 seconds. Subsequently, it takes about a second to produce
and display a new map." |

All assembled What can SVFIG do to promote Forth? |

Sneak Preview: Quantum Computing - Jack
Woehr Jack has volunteered to do our first remote "Hangout" presentation
in October. Hell give us a short preview of what he will be talking
about. Please be patient as we have never done this before and it may take a
little iteration to get the technology to work.
- Here are some of Jack's writings:
- QM/QC
: The Hdirt Factor: A chat with John Martinis
- Camera
Excursion to the NIST Ion Trap Quantum Computing Experiment
- Quantum
Memory: A Chat with Ian Walmsley

The First Application for the Kestrel-2 - Samuel A.
Falvo II "I had no idea what I wanted to present to SVFIG, but I knew I
wanted to use the Kestrel-2 to make the presentation. That meant I needed a
slide projector program for the Kestrel-2, which I had to write from scratch.
So, I'm writing one, thus giving me something to talk about this SVFIG
meeting."

Random Access - All assembled We'll ask for
volunteers to provide short presentations. We may discuss Forth Day and
suggestions for promoting Forth in general. Other topics might include the
Arduino, the LaunchPad, new products, comp.lang.forth and whatever else occurs
to us. |

I wrote a proof-of-concept implementation for gforth and
ported it to pforth, and Gerry Jackson ported it to iforth, swiftforth,
vfxforth, and win32forth. It's basically a recursive one-time file loading
scheme with path search. It has switchable behavior so you can either run it
interpretively or compile load files so as not to require any extra runtime
support on the target system. It's very rough and simplistic yet and has a long
way to go (I'm hoping to be ready for a formal initial release by January) but
I think it has a lot of potential. - Josh
