Minimised Hash Code for Maximising 3D Collaborative World Building with Forth Derived Metaprogramming Shell - Liang Ng
"Consistent with the law of 'less is more', I will demonstrate how a minimised hash code derived from the hash of public key plus arbitrary strings representing 3D objects such as GLTF can become a unifying representation for various object formats, with operations expressed in Phoscript, a metaprogramming shell language derived from Forth."

End of the Meeting

Not presented

Machine Forth for RISC-V - Samuel A. Falvo II
"I am resurrecting some old Forth compiler ideas I never got around to implementing until now. My interpretation of Machine Forth for RISC-V - details are shown in the video linked below!"

Future

CoSy Update - Bob Armstring
"I can talk on progress toward eclipsing the trade computing environments with Forth CoSy for the ultimate target market of female entrepreneurs who consistently compare CoSy with Evernote and Notion, both of which have ~ $B valuations after a couple of $100m investments. But both don't have the radically open foundation provided by Forth. (Notion does evolve from SmallTalk.) "

Automatic Differentiation in Forth - Brad Nelson
"I'll explore using Forth Recognizers to implement automatic differentiation and explore differential programming."

Forth Recognizers in SwiftForth
Automatic Differentiation
Differentiable Programming

Windows Shell Support in Win32Forth - Bill Ragsdale
Bill will examine the three levels of direct user's Forth interface to a Windows based PC.

Creole Forth and Picar-X, Part 2 - Joseph M. O'Connor
Joseph will continue his presentation of Creole Forth for Python which he used to develop commands for the Picar-X robotic car.

Smart Token System - Don Golding
Don will discuss a combination of Color Forth constructs: a packet like structure for the cell.

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