LuaCAD models solids in Lua rather than the OpenSCAD language, with operator overloading for CSG (`a + b`, `a - b`, `a * b`).It ships with a CLI and a desktop app, including a preview area and a text editor.I've always been a big fan of OpenSCAD, but the SCAD language itself is unfortunately quite cobbled-together and is a very poorly designed programming language.LuaCAD takes all the good parts of OpenSCAD and combines them with one of the best scripting languages. It has now completely replaced OpenSCAD for me, and I think it provides a better experience than OpenSCAD for all use cases. I'd love to hear any reasons why LuaCAD shouldn't fully replace OpenSCAD!It’s fully open source and you can find the repo here: https://github.com/ad-si/LuaCADTech stack:- It's implemented in Rust and uses mlua (https://github.com/mlua-rs/mlua) to execute the Lua code.- Uses OpenCSG (https://opencsg.org) for fast and correct rendering of the 3D models (like OpenSCAD)- Uses Manifold (https://github.com/elalish/manifold) to create the manifold triangle meshes- Native support for all BOSL2 functions (i.e. implemented in Rust for better performance)

Creating .oiv modpacks for GTA is tedious and error-prone due to buggy project manager software, forcing manual editing of assembly files.

BreezePDF lets you edit, sign, merge, compress, redact, OCR, fill forms, extract tables, and use 30+ more PDF tools — all in the browser, no sign-up. Files never leave your computer.I built it because when people search Google for common PDF tasks, many of the tools they find upload documents to a server. I wanted an option that keeps files local instead.I posted an earlier version on HN last spring: https://news.ycombinator.com/item?id=43880962At the time it only supported a small set of features. Over the last 10 months I rebuilt large parts of it and expanded it to nearly 40 tools, including several ideas that came from comments in that earlier thread.There is also now a desktop app for macOS, Windows, and Linux, plus a CLI/SDK for developers.
