Pad.ws – Whiteboard IDE is now open-source
Pad.ws is an infinite canvas that runs Linux, you can draw, write, open terminals or vscode to your very own ubuntu workspace. This uses Excalidraw for the canvas part while Coder manages the dev environments. We have a Public hosted instance at https://pad.ws if you want to try it out Disclaimer: this project is still very early, your feedback helps us shape it, so please let us hear your ideas!
In plain words
Pad.ws is an infinite canvas application that combines drawing and writing capabilities with a Linux environment running Ubuntu. Users can sketch on the canvas, open terminals, and access VS Code within their own workspace. The tool integrates Excalidraw for the canvas interface and Coder for managing development environments. It is designed for developers who want to blend visual planning with coding in a single integrated space. The project is open-source and currently in early development.

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
