Bytecode Virtual Machines in Unexpected Places: From SQLite to the Linux Kernel
Summary
A blog post exploring the use of bytecode virtual machines in unexpected places, starting with Richard Hipp's explanation of why SQLite uses a bytecode VM for executing SQL. The article highlights eBPF (a bytecode interpreter and JIT compiler inside the Linux kernel) as a surprising example, and likely continues to discuss other unconventional uses of bytecode VMs beyond general-purpose programming languages.
