Meeting of January 13, 2022

Present: Art Anger, Will Gajate, Raul Miller, Bob Therriault.

  1. Will reported that Joe has made substantial progress on the 32 bit emscripten version of J804. Work remains to see if it can work with the 64 bit version of J903. A fallback could be the 32 bit version of J903 used for the Raspberry Pi, but at this point the 64 bit version is still the target. There is future work to do on the interface and checking that forks and other modifiers are functioning properly. Also planning to move the files from the current 3rd party GitHub to the Jsoftware GitHub to ensure stability.
  2. Bob ran a draft video 'billboard' for newcomers designed to attract interest and direct viewers to resources where they can get more information about the language. The goal of the video is to show off the language, not to explain all the terminology because if we can't get them interested, they won't take the next step to learning. Suggestions were to make more use of animation, convert some classic equations into J for comparison, and perhaps show the connection between Sierpinski fractals and Pascal's triangle. Video can be watched here: youtu.be/oYRUY0ZfFus (it is a draft, future version may be done with Keynote to allow for highlighting of different operations).
  3. Art told of cross indexing his J summary of 4000 terms and found 336 cross references. He is now looking to build a semantic web to see if there are patterns in how the terms are linked to each other.
  4. Raul showed how to calculate phi (the golden ratio) to 256 decimal places using the Fibonacci ratios. Fibonacci is one of the examples that may be used in future introductory videos.
