Notepad.exe – macOS editor for Swift and Python (now Linux runtime)
I recently released version 1.4 of Notepad.exe, my editor built for macOS. The goal of the app is to let you prototype ideas in Swift or Python with minimal setup - write code, hit Run, skip project scaffolding. This release adds support for a Linux runtime/subsystem, so you can write on macOS and execute snippets in a Linux environment. I’d love to hear any feedback or answer any questions: would a tool like this fit your workflow? What friction remains?

From the sources
Notepad.exe is a Mac code editor for Swift, Python, JavaScript, Go, and Rust. Run files instantly, build with an on-device agent, test on Linux, and export Mac apps.
Five lines of code shouldn’t need a project. Notepad.exe is a lightweight Mac code editor that opens on a blank note. Run a file right away, then pull in packages, test on Linux, or build for Apple platforms from the same app. Open a file, hit Run, and see what happens. Notepad.exe is quick for scratch work, but it still has room for packages, platform testing, and app work. It writes the same code you’d write by hand. You can read it, edit it, and learn from it. Try scripts, snippets, CLIs, and UI experiments from one editor without setting up a full project first. Run SwiftUI and UIKit ideas in Simulator when an experiment needs a real screen. Keep quick experiments close to…from notepadexe.com

NotepadJs – A cross-platform love letter to Notepad2025 · github.com · ▲145As a native Windows user who switched to macOS a few years back, one thing I never got over was the simplicity and usefulness of the old school Notepad app. This app aims to recreate that very same experience, cross-platform and easily installable as a PWA. I've been using this for personal use for around 2 years and I figured it was time to share it with the world. Criticism, issues and PRs are welcome. Thanks!

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
