But I often want to factor in the opposite direction: run the same high-level program, but swap out the interpretations of the words. Hen is an experiment in adding this capability to Forth. It leads to some interesting patterns, and avoids the boilerplate of dependency injection in C++ and the complexity of monad transformers in Haskell." 2026-08-22 09:35:35 From Juergen Pintaske to Everyone: Hi Brad, is there anything new about your Lattice work? 2026-08-22 09:35:50 From Curtis Jones to Everyone: To get APL Bay Area Users' Group notices ask me - curtis_jones@ieee.org 2026-08-22 09:36:44 From Curtis Jones to Everyone: And Bob Armstrong here has serious APL experience. 2026-08-22 09:37:37 From Program Chairman Kevin to Everyone: But serious in a light-hearted way 2026-08-22 09:37:51 From Sellam to Everyone: Hello, I'm Sellam Ismail.

I was sad to see the VScode polynotebooks get dropped 2026-08-22 10:31:39 From Program Chairman Kevin to Everyone: I prefer to have actual files in preference to links. Links tend to become cob-webs over time. Winchester Mystery pointers. URLs that go nowhere. 2026-08-22 10:32:43 From Samuel A. Falvo II to Everyone: "Winchester Mystery Pointers" -- stolen for future use! 2026-08-22 10:35:30 From Samuel A. Falvo II to Everyone: Hmm...but not all errors are exceptions. 2026-08-22 10:35:33 From Brad Nelson to Everyone: I think the tendency towards panics in Go is based on a server centric assumption the safest way to fail is bring the whole process down. 2026-08-22 10:37:00 From M Edward Borasky (@znmeb) to Everyone: Replying to "GForth isn't supported in Windows yeah, so IForth ...": Hmmm ... maybe we can talk someone into packaging `gforth` in `conda-forge`. That would make it available across the major desktops in Conda environments. https://urldefense.com/v3/__https://conda-forge.org/docs/tutorials/building-locally/__;!!G92We9drHetJ8EofZw!Y4IGxWYj6k5aed4OTazoz6op4BRXu5Q5enMvjE_BkuU75aw6XCXRS4iNlq6nPzHQPvVNpmi6g60zJTHWwSsk$ 2026-08-22 10:36:59 From Program Chairman Kevin to Group chat - JoeS, Brad Nelson, Program Chairman Kevin: Get with Brad if you want to address Zoom audio quality issues. 2026-08-22 10:37:08 From Program Chairman Kevin to Group chat - JoeS, Brad Nelson, Program Chairman Kevin: Keep me posted! 2026-08-22 10:38:23 From Samuel A.

Falvo II to Everyone: If you recall my various Forth coding style talks over the years, you might remember that I said I used HERE / ALLOT as a means of managing memory at run-time. That is a very simple "arena". Same idea. 2026-08-22 11:10:46 From Program Chairman Kevin to Everyone: That was a redo of the Falcon. Quite an impressive reanimation, you can see the guy's talk in the YouTuber. 2026-08-22 11:11:20 From Samuel A. Falvo II to Everyone: The Amiga was the LED-illuminated machine behind the Falcon. 2026-08-22 11:12:39 From Samuel A. Falvo II to Everyone: Wasn't the DataPoint 2200 the machine that gave us the 8080 instruction set? 2026-08-22 11:12:56 From Program Chairman Kevin to Everyone: There was a great YouTube video about the DataPoint, being the first PC 2026-08-22 11:12:59 From Curtis Jones to Everyone: That IBM 5100 had the APL feature.

Processor was popular in space applications and mil for a while. 2026-08-22 11:16:20 From Samuel A. Falvo II to Everyone: The Alto is the only machine that you could say was "multi-threaded", but only at the microcode level. Interesting architecture; I recommend reading up on it via the Internet. Everything else were single-core, single-thread. 2026-08-22 11:16:29 From Program Chairman Kevin to Everyone: John Rible has spoken of Sphere 2026-08-22 11:16:42 From Samuel A. Falvo II to Everyone: The TMS9900 is a niiiiice CPU. 2026-08-22 11:17:00 From Martin Andronikos to Everyone: the ti99/4 used the tms9900 which was 16 bit words but it only had a tiny bit of direct access memory and the rest was byte-wise behind the video chip afak 2026-08-22 11:17:04 From JoeS to Everyone: i wanted a NeXT machine so badly... would have been 1/2 my salary the year it came out 2026-08-22 11:17:07 From Adrian Cabrera to Everyone: Has NASA been using Forth for any of their programs lately? 2026-08-22 11:17:32 From Program Chairman Kevin to Everyone: Grid was popular in aviation, mil, and on the Space Shuttle 2026-08-22 11:17:37 From Bob Armstrong to Everyone: Ran CoSy on GRiDs for years . 2026-08-22 11:18:09 From Curtis Jones to Everyone: Bob, A Grid with bubble memory? 2026-08-22 11:18:11 From Samuel A. Falvo II to Everyone: Replying to "the ti99/4 used the tms9900 which was 16 bit words...": Correct; it was originally specced to use a 6502, but TI management said NO, but was also not allowed to redesign the rest of the machine, and ham-strung the machine ever since. 2026-08-22 11:18:12 From Martin Andronikos to Everyone: ooh that sony laptop had a crusoe sticker on it! 2026-08-22 11:18:26 From Martin Andronikos to Everyone: transmeta crusoe 2026-08-22 11:18:49 From Bob Armstrong to Everyone: No . but good service contract . 2026-08-22 11:19:29 From Adrian Cabrera to Everyone: Oh man that Apple laptop.
