Interpreter alignment chart
This alignment chart explores what counts as an "interpreter" across two dimensions: implementation (what form the interpreter takes) and input (what it processes). Implementation Axis Implementation Purist: An interpreter must be a program—software that executes on a computer. Implementation Neutral: An interpreter must be electronic—it can be hardware or software, but requires circuits and electricity. Implementation Rebel: An interpreter can be anything—no restriction on physical form or medium. Input Axis Input Purist: An interpreter works on a program—it must execute formal code or instructions. Input Neutral: An interpreter works on text—it processes symbolic or written information. Input Radical: An interpreter works on anything—no restriction on input type. Examples Across the Spectrum Lua (program processing programs) CPU (electronic processing programs) CEK-Machine (anything processing programs) Excel (program processing text) LLM (electronic processing text) Shredder (anything processing text) Doom (program processing anything) TV (electronic processing anything) Choir (anything processing anything)

@keleshev.com not sure whether you already saw, but Compiling to Assembly from Scratch got a review in c't 9/25 (the largest German IT magazine)

Since I was now wondering, here's PyPy VS CPython 3.x binary sizes
Plot of CPython and PyPy binary sizes over time. CPython 3.7 is 35 MiB, shrinks to 22.5 MiB in 3.8, then slowly grows again until 3.11 at 25.2 MiB. Cpython 3.12 is much bigger, at 37.3 MiB. CPy 3.13 shrinks a bit again to 36.1 MiB. PyPy tracks the ups and downs in roughly the same shape but is generally much bigger. 3.7 is at 60.5, 3.8 at 56.2, then it slowly increases to 58.8 at PyPy 3.11
