At the Gambit@30 conference, Marc Feeley explains the GVM... building supercombinators for a register + stack machine using C macros with retargetable implementations... and now backends to JS, Java, PHP, asm(x86, ARM, RISCV)... 1/

#Gambit Scheme, in which you can update the drivers while the machine is running.Show this thread -
Marc Feeley explains how to migrate tasks from one machine to the other, how to serialize continuations and everything that entails, how to use a trampoline but not too often, how to avoid space leaks between the GVM and target language GC...

Barbara Samson and Guillaume Cartier show their portable real-time interactive 3D video and audio environments written in Jazz Scheme on top of Gambit… including an interactive spreadsheet to visualize why UDP packets have being dropped during the interaction's past.

Guillaume's Jazz Scheme has its own windowing system all written in Scheme, on top of Gambit. The system does everything in OpenGL and is portable to macOS, Windows and Unix/X11, including its own self-debugging graphical debugger.

Jazz was originally written in C. Rewritten in Scheme in 2 years. The original rewrite was 80x slower than C, because it was doing too many function calls; making them macros to inline code, then adding types—and it's now faster than it was in C. And much more productive.
