The Remarkable Projects of Super Programmer Justine Tunney

Justine Tunney is portrayed as a "super programmer" whose technical depth and breadth far exceed the average developer.

Her notable projects include:

1. RedBean Web Server – a C‑written web server that can run the same binary on six different operating systems by leveraging the APE (Actually Portable Executable) format.

2. Cosmopolitan libc – a custom C standard library designed to work across platforms, enabling true "write once, run anywhere" for C programs.

3. sectorLisp – the smallest Lisp implementation (512 bytes) that can boot directly from a PC BIOS, showcasing low‑level programming skill.

4. Blinkenlights – originally a command‑line debugger visualizing memory changes, it also functions as a compact x86 emulator.

5. RoseHub – a project launched after discovering a deserialization vulnerability in Apache Commons, recruiting 50 Google engineers to fix thousands of GitHub projects.

6. llamafile – a collaboration with Mozilla that packages large language models into a single executable using cosmopolitan libc, runnable on six operating systems without additional dependencies.

7. Console Video Output – a technique that decodes MPEG streams into colored characters to display video directly in a terminal.

The article also mentions Tunney's early start in programming, her work at Google’s TensorFlow team, involvement in the Occupy Wall Street movement, and her ambitious vision for technology’s role in society.
