Project ideas from Hacker News discussions.

F*: A general-purpose proof-oriented programming language

📝 Discussion Summary (Click to expand)

Three dominant themes in the discussion

  • Lack of accessible examples

    "Clicked like 5 pages and never found 1 code example!" – cyanregiment
    "I still don't see any code examples!" – cyanregiment

  • Proof‑oriented focus, not typical “hello‑world” problems

    "These are not the kind of problems which are related to [\"HTTP server\", \"hello world\", \"todo list app\", …]." – cyanregiment
    "Often the reason [...] the examples how to write something in it are merely the 'more boring' consequences of this different way of thinking." – aleph_minus_one

  • Usability and design friction

    "F is the dwarf fortress of programming languages. Screenshots are only going to confuse anyone who isn't ready to take a significant mental journey." – Verdex
    "Could not start SMT solver process. Command: '/home/site/wwwroot/fstar/bin/z3'" –

🚀 Project Ideas

[F* Playground & Example Hub]

Summary

  • A hosted, zero‑setup browser REPL that ships with a curated set of “Hello World”, “HTTP server”, and “Todo list” examples for F* and dozens of emerging languages.
  • Users can instantly see syntax, edit, run, and see proof checks without leaving the site.

Details

Key Value
Target Audience Newcomers to proof‑oriented languages, educators, conference speakers
Core Feature Pre‑loaded interactive snippets (e.g., minimal HTTP server) that compile/run instantly in WebAssembly‑based sandbox
Tech Stack React front‑end, Monaco editor, WebAssembly F* interpreter, Firebase Hosting
Difficulty Medium
Monetization Revenue-ready: Freemium (free sandbox, paid premium tutorials & CI pipelines)

Notes

  • Directly answers the HN complaints “I clicked like 5 pages and never found 1 code example” and “What does the syntax look like”.
  • Sparks discussion about language ergonomics and proof‑oriented use cases.

[Code Example Spotlight Widget]

Summary

  • A lightweight JavaScript widget that scans documentation homepages and injects prominent “Run‑Now” buttons for sample code blocks.
  • It automatically creates a one‑click sandbox for each highlighted example, removing the “click‑through” friction.

Details

Key Value
Target Audience Language designers, maintainers of programming‑language sites, technical writers
Core Feature Auto‑detects code fences, wraps them in an interactive Playground iframe, supports multiple languages
Tech Stack Vanilla JS, iframe API, Serverless function for code execution, Cloudflare Workers
Difficulty Low
Monetization Hobby

Notes

  • Solves the exact pain point raised by “cyanregiment”: “I wonder why more languages don't have a few simple examples … that you can just click and it shows the code”.
  • Generates discussion about tooling improvements for language adoption.

[Open Source Demo Gallery for New Languages]

Summary

  • A community‑curated gallery where each language gets a dedicated page with a minimal, fully functional project (e.g., “hello world”, “todo app”) plus a live demo link.
  • Includes downloadable source, README, and a “Why use this language?” blurb.

Details

Key Value
Target Audience Language creators, learners evaluating new languages, recruiters
Core Feature Template repository with CI‑enabled build, Dockerized demo, sample implementations across domains
Tech Stack GitHub Templates, GitHub Actions, Netlify for live demos, Markdown documentation
Difficulty High
Monetization Revenue-ready: Sponsorship model (GitHub Sponsors) + paid custom templates

Notes

  • Provides the missing “what does a simple solution look like in F*?” and “why would I use this language?” answers that were repeatedly requested.
  • Will generate discussion threads around each language’s design choices and practical utility.
