Fireside Q&A- Charles H. Moore
Chuck will tell us what he's been doing and then take questions.

FPGA and ASIC Forth Market Strategy - Christopher Lozinski
"When FPGA finite state machines become too complex, many engineers choose a RISC-V soft core. However, the abundance of RISC-V soft cores available can lead to market confusion. To address this, I developed a RISC-V soft core directory to assist in selection and to promote Forth interpreters on RISC-V for FPGA hardware debugging. I seek support in this initiative. Once the Forth language is adopted, it will be easier for engineers to adopt a Forth soft core, which is approximately half the size of the smallest 32bit RISC-V soft cores."

"On an ICE40 FPGA, a stack machine can be half the size of a 32-bit RISC-V soft core. On an ASIC, a stack machine can hold 6 instructions in the space occupied by one RISC-V instruction."

The CORE I Project - Don Golding and Demitri Peynado
"We will give an update on the CORE I project. Demitri will speak about the most important aspect of CORE I - the code - and I will follow up with the status of the CORE I hardware."

CLAMS - The Quest for Portability and Audio - M. Edward (Ed) Borasky
"I have c3 running on Linux, as well as on a Teensy 4.1 and an Adafruit Feather RP2350 with HSTX in the Arduino IDE. I hope to demonstrate a Forth-controlled synthesizer running in the Teensy 4.1 generating USB audio."

ESP32Forth talks to Gemini - Brad Nelson
"I'll explore using ESP32Forth with the Gemini API to bring LLMs to a low-cost embedded device."

Forthic - Rino Jose
"Forthic is a high-level Forth designed to build web-based tools at LinkedIn. It can be embedded at any level of an application, enabling extension even after deployment."

GTK4 Object Mapped to SWOOP Classes - Leon Wagner, FORTH, Inc.
"We recently ported a Windows GUI control application to GTK4 for cross-platform compatibility. I will show how the GTK object model maps nicely to SWOOP classes and results in some pretty readable Forth code."

Programming Languages vs Spoken Languages - Doug Hammed
"I will discuss the difficulty in learning a programming language"

Primitive Words to Bootstrap a Forth - Bill Ragsdale
"What would be the most primitive words to implement in code for a minimal, low performance Forth?"

Slides - Forth with Small Silicon

Latest Additions in zeptoforth - Travis Bemann
"There have been a number of significant new developments with zeptoforth over the past few months. The most important are RP2350 support and including current directories to the FAT32 implementation. Hardware single-precision floating point and complex number support are in the works."

BANDIT ColorForth Keyboard - Julian Roca
"I'll show a short video about this interesting implementation."

From Technofeudalism to Technosocialism: Forth Unexpected Roles in Decentralized Systems - Liang Ng (Malaysia)
"I'll compare blockchain based decentralized systems with a more lightweight architecture called Omni Star Web, where a Forth based shell that can be added to web based or mobile applications performs various decentralized and user defined functions. Omni Star Web implements a hash based secure decentralized universal data sharing protocol, effectively creating a shadow Internet owned and operated by free individual users and free software programmers."

CoSy, an Everyday Human Level System Based in Forth, not C - Bob Armstrong
"The truly unique aspect of CoSy is that it is simply a vocabulary in Forth with Forth's unique simplicity and openness to the hardware - rather than mass market C or other foundational languages like Rust."

Video (27:00)

GreenArrays Update - Greg Bailey
Greg will discuss the current status of GreenArrays.

KolorScript - George Phillip Orais
"I will introduce KolorScript, which is closely related to colorForth."

End of Meeting

Future

TBD - Joseph O'Connor
"I can give a presentation on using Creole Forth with the Picar-X, a robotic car that works with a Raspberry PI. If this doesn't fit in for Forth Day, I can do it in December."

Getting Started with arrayForth - Greg Bailey
"I will present a video on the simple process of downloading, installing, and using arrayForth 3."

Direction Finding - Andrew Korsak
Andy is planning to present this application on Forth Day.

Building GUIs in Forth, without the Gunk - Xuyang Chen

Fiji - Jack J. Woehr
