I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

# DESCRIPTION
|
||
#
|
||
# This file defines the libraries, runtimes, and build rules needed to
|
||
# create executables from your Linux workstation that'll run anywhere.
|
||
# Loading this package will make certain systemic modifications to the
|
||
# build like turning off the System V "Red Zone" optimization, because
|
||
# αcτµαlly pδrταblε εxεcµταblεs need to be able to run in kernelspace.
