LaunchPad and Bach - CH Ting
"I am thinking of
using the Arduino Uno to play 6-part Bach organ pieces. I will work on it in
the last week of August and show the results in the meeting. I think I can get
the six servo channels to drive 6 speakers and play polyphonic music. I can
generate frequencies to an accuracy of 1.6%. I hope it will be good enough for
Bach." |

Literate Programming Database Tool - Dennis
Ruffer
Dennis has a Literate Programming version of the database tool he
has been carrying around since his early days at FORTH, Inc.
- "I have updated the Database Support System, using Literate
Programming techniques, to be stand alone and compatible with 64-bit
systems."

Steamer-16 Processor Architecture - Samuel A. Falvo
II
"When attempting to fix the keyboard bug in the previous Kestrel-2
implementations, it was discovered that a ground-up redesign was in order.
However, getting the original J1 development tool-chain working again to test
this new design with proved sufficiently problematic to want to redesign that
as well. Not originally anticipating it'd become the main CPU for the
Kestrel-2, I adopted a MISC style processor called the Steamer-16 because it
was trivially easy to program and realize in hardware, even from an 11-year old
recollection of the architecture. My version of the Steamer16, the S16X4, has
proven easy to extend and to document in the fullest detail."

Event-Driven Programming in Forth - Brad
Nelson
We will discuss what event driven programming for asynchronous
I/O should look like in Forth. Closures and Continuations in Forth will
be considered. We will explore what frameworks like Twisted and Node.js might
look like if implemented in Forth.
