Show HN: Astroworld – A universal N-body gravity engine in Python (github.com)
I’ve been working on a modular N-body simulator in Python called Astroworld. It started as a Solar System visualizer, but I recently refactored it into a general-purpose engine that decouples physical laws from planetary data.Technical Highlights:Symplectic Integration: Uses a Velocity Verlet integr...

Show HN: PostForge – A PostScript interpreter written in Python (github.com)
Hi HN, I built a PostScript interpreter from scratch in Python.<p>PostForge implements the full PostScript Level 2 specification — operators, graphics model, font system, save&#x2F;restore VM, the works. It reads .ps and .eps files and outputs PNG, PDF, SVG, or renders to an interactive Qt window.<p...

Show HN: Master Golang, Fullstack Go web dev course, scratch to production (mastergolang.com)
I’ve been building production Go web apps for the past 7 years. One gap I kept running into: most Go resources teach syntax well, but stop before things actually look like production.<p>So I built the course I wish I had.<p>You build a real app from start to finish: a blog with authentication and an...

Show HN: Carbon-aware scheduler for batch ETL jobs (Python) (github.com)
I built a Python tool to defer heavy batch ETL jobs (like Snowflake&#x2F;Airflow) when the local energy grid is &quot;dirty&quot; (high carbon intensity). It uses real-time grid APIs to find green windows. Would love feedback on the logic!

Hi HN,<p>I&#x27;ve been building elecxzy, a lightweight, Lisp-free Emacs-like editor using Electron, React, and TypeScript.<p>I couldn&#x27;t really find a modern, zero-config Emacs alternative built on web tech that drops Lisp entirely, so I decided to build my own to scratch that itch.<p>Under the...
