Hi all, I'm looking for some volunteers to test the latest J Playground on their mobile device.
https://jsoftware.github.io/j-playground/bin/html2/ Many people reported that the Playground was unstable on their mobile devices or devices with more limited memory. I also experienced it intermittently. The latest playground change sets a parameter to initialize memory to 32MB (using TOTAL_MEMORY aka INITIAL_MEMORY)[1]. My working theory is that the default 16MB caused the heap to expand which stressed the lower memory/mobile device. I've tested on my Samsung FE20 and an older original Google Pixel from 2016 and both devices could use the playground examples without crashing the browser. A future step could be to make a more mobile-friendly version of the playground. The current version works reasonably well yet I'm thinking there could be some things we do to make it easier to work with on a device with a smaller screen. Also, work has been done to fix some issues in the original adjustments to the source code to get it to build under emscripten/WASM. The changes fixed 7 failing test files (e.g. g200, g131) and fixed some issues with surface plots and other glitches. If you test, please either reply-all if there hasn't been much reporting on the issue or reply to me directly if it seems too noisy on the mailing list or if you'd prefer to send directly. Thanks for the help Joe 1 - https://github.com/jsoftware/j-playground/commit/0f022dea1706ebd0dc0900ff06fb4f81d896d6a9#diff-d42f4e1542def2ab6129051634fec87b7578f9d109918947ca2a0597a524be21R30 2 - https://github.com/emscripten-core/emscripten/blob/main/src/settings.js#L170 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
