4️⃣ Linux Inside a PDF 🐧📄

Yes, you read that right! Linux running inside a PDF file via a RISC-V emulator. Insanely cool project! 🔗 Try it: 🌟 Star this repo:

ading2210 / linuxpdf

Linux running inside a PDF file via a RISC-V emulator

LinuxPDF

This is Linux running inside a PDF file via a RISC-V emulator, which is based on TinyEMU.

Try it here: linux.pdf

linuxpdf.mp4

See also: DoomPDF

Explanation

This works in a very similar way to my previous DoomPDF project.

You might expect PDF files to only be comprised of static documents, but surprisingly, the PDF file format supports Javascript with its own separate standard library. Modern browsers (Chromium, Firefox) implement this as part of their PDF engines. However, the APIs that are available in the browser are much more limited.

The full specfication for the JS in PDFs was only ever implemented by Adobe Acrobat, and it contains some ridiculous things like the ability to do 3D rendering, make HTTP requests, and detect every monitor connected to the user's system. However, on Chromium and other browsers, only a tiny subset of this API was ever implemented…

🎨 Diagram-as-Code: Creating Dynamic and Interactive Documentation for Visual Content

Diagram as Code is an approach that allows you to create diagrams through code instead of traditional graphic tools. Instead of manually building diagrams, you can write code in a text file to define the structure, components, and connections of your diagrams.

This code is then translated into graphical images, making it easier to integrate and document in software projects, where it is especially useful for creating and updating architectural and flow diagrams programmatically.

What is Diagrams?

Diagrams is a 🐍Python library that implements the Diagram as Code approach, enabling you to create architectural infrastructure diagrams and other types of diagrams through code. With Diagrams, you can easily define cloud infrastructure components (such as AWS, Azure, and GCP), network elements, software services, and more, all with just a few lines of code.
