Gimp Plug-ins in Forth - Brad Nelson
Forth
Haiku demonstrates that tiny Forth programs can concisely express complex image
generation. The Gimp image editor proves to
be a powerful toolset for manual image editing. This toolset can be expanded by
means of plug-ins, typically implemented in C.
Brad will present a technique to implement Gimp plug-ins using
Gforth. Using this approach,
a plug-in that implements a variation of the Haiku Forth vocabulary will be
demonstrated. He will explore how the generation technique used for Forth Haiku
can be expanded to express image filtering and transformation, enhancing Gimp
with Forth's unique power of expression. |

Nelson
Brad will present a short video, a collection of the best of
Forth Haiku. |

Converting Stack Code to Efficient Register Code -
Samuel A. Falvo II
Sam will briefly illustrate how to convert stack
code inside a single "basic block" into static-single-assignment form, which
when used together with conventional register allocation algorithms, results in
near optimal register-based code. |
|
09:50 |
A Multicore Breakout Board Project - Sandy
Bumgarner
Sandy will present a versatile breakout board project that
uses a slightly obscure multi-core processor which has 8 'cogs', and runs a
version of Forth. The whole project fits inside an attractive plastic
enclosure. The PCB design will be supplied as well as the bill of materials and
related necessary parts. It performs GPS calculations and produces video so it
can be programmed to make useful and interesting gadgets. |

Implementing Forth on the RCA 1802 - Harold
Rabbie
Harold will discuss porting Forth to this 40-year old
resource-starved processor architecture. |

Bare Metal ... Batteries Included - James
Bowman
swapForth is an efficient self-hosted 32-bit ANS Forth running on
a one-chip microcontroller. It has an extensive set of peripheral drivers
making it suitable for embedded applications.

C Macros for the Arduino eForth Dictionary - John E.
Harbold
John will present ANSI C macros that can be used to create a
Forth dictionary structure for eFORTH running on the Arduino using a
development system based on GCC. |

Job Ads Year in Review - Dennis A.
Ruffer
Dennis will look back at last year's Forth job postings. While
there are no jobs that require Forth exclusively, there are a few that still
mention Forth as a programming skill they deem desirable in their candidates.
Dennis uses an Indeed.com filter to find postings that mention Forth, while
excluding any non-computer-language specific usages of "Forth".

Forth RF Data Link Controller - Bob Nash
Bob
will describe his new product: a point-to-point or multi-drop RF link
controller using a Forth-programmed processor and an inexpensive ($3) RF link
board that uses an RS-232 command set.
