 These should be good for people who want to understand what's going on and maybe contribute to the core, and it's great to see Mason develop that understanding himself also.
+==== Keyboard refactoring ====
+  * Andrés: This month mostly consisted of working with Mason's [[https://github.com/FolkComputer/folk/pull/208|old PR code for keyboard improvements]] that would allow code views and interactive tabletop editing of programs in folk1 and beginning to rewrite it for folk2. This will take shape next month as a new PR fit for extending folk2's editor.

 The ''$quadLib change'' function was doing a synchronous Query! to find any changers that are around to convert from one space (like camera-space) into another space (like projector-space).
-I got rid of the 'quad-local space' that all quads used to be specified in; now they all are in camera space immediately. Then I replaced the whole space-changer system with a single claim that exposes a changer that knows how to convert any known space to any other known space, since now this only changes with the calibration anyway (so almost never).

 === WIP: Speed up the animation port ===
-Recall from last month.
+Recall that we [[newsletters/2025-08#animation-demo|ported animation to folk2 last month]]. That port works OK, but it degrades as you put more programs on the table, timing messes up, and it makes a lot of Holds and takes up a lot of GPU slots and stuff because of all the synthetic objects.
-Don't actually need a canvas per frame box.
+We don't actually need a canvas per frame box, so I've been trying to write a version that just has quads for the frames (to get camera slices) but no canvases, and which draws everything straight to the display buffer.
-==== Other improvements ====
+That led me to realize that the ''quadChange'' I did earlier doesn't handle inverse changes, so I just added those. Haven't gotten to finish this yet, though.

 An especially small one this time, but we had the studio open all afternoon, and it was great to cowork with Mike (who came in from Baltimore) who was playing with audio stuff.

 ===== What we'll be up to in October =====
   * Omar: Probably merge folk2
+    * Omar: Try to fix some remaining crashes
+    * Omar: Try to test -atomically in production
+    * Omar: Work on animation port
   * Omar: Continue trying to configure gadget projector
   * Omar: Maybe stereo-calibrate gadget and do some UI experiments with the full stereo setup (segmentation, projection-mapping, lassoing)
+  * Andrés: Porting core Folk drawing Wishes to Folk2
+  * Andrés: Work on refactoring keyboard to be more easily improved and extended (e.g. text resizing, interactive editing of table programs)
+  * Andrés: Possibly revisit video branch to get support merged into folk2
