🗣️ Post 1: Show HN: Pyscn – Python code quality analyzer for vibe coders

💬 Summary

Hi HN! I built pyscn for Python developers in the vibe coding era. If you're using Cursor, Claude, or ChatGPT to ship Python code fast, you know the feeling: features work, tests pass, but the codebase feels... messy.

Common vibe coding artifacts:

• Code duplication (from copy-pasted snippets)

• Dead code from quick iterations

• Over-engineered solutions for simple problems

• Inconsistent patterns across modules

pyscn performs structural analysis:

• APTED tree edit distance + LSH

• Control-Flow Graph (CFG) analysis

• Coupling Between Objects (CBO)

• Cyclomatic Complexity

Try it without installation:

  uvx pyscn analyze .          # Using uv (fastest)
  pipx run pyscn analyze .     # Using pipx
  (Or install: pip install pyscn)

Built with Go + tree-sitter. Happy to dive into the implementation details!

🗣️ Post 3: Show HN: I am relaunching the app I made to talk to my Danish girlfriend

💬 Summary

It has been a while since I have shared my app, that I made to be able to practice my Danish while chatting with my grilfriend - I often used GPT to write as much as I can in Danish, and I replaced the words I didn't know with {Englis words in curly braces}. While this was great, it was rather annoying to type the prompt always, so I figured a GPT wrapper would work well here.

Last time when I launched, it went viral! I was super happy (and grateful!) for all the feedback and excitement — but it also meant my tokens disappeared fast, and many people ended up trying an app that no longer worked...

So… I took a step back, trimmed a few auxiliary features, and started porting the whole thing over to Supabase with proper rate limiting.

It’s still a work in progress, but the core functionality is up and running — you can write in your target language, add words that you do not know (or context) in {curly braces}, and get a corrected version with explanations.

I figured I’d share an update now instead of waiting until everything’s perfect — would love to build it in the open and keep you all in the loop this time.

🗣️ Post 4: Sora Is an Unholy Abomination

💬 Summary

is a senior editorial director at Vox overseeing the climate teams and the Unexplainable and The Gray Area podcasts. He is also the editor of Vox’s Future Perfect section and writes the Good News newsletter. He worked at Time magazine for 15 years as a foreign correspondent in Asia, a climate writer, and an international editor, and he wrote a book on existential risk. Really, it’s almost unfair to hold a tech company to its mission statement. From Google’s “Don’t Be Evil” to WeWork’s “Elevate the World’s Consciousness,” mission statements are usually written in a company’s adolescence, at that awkward moment when their dreams stretch to the horizon, the venture capitalists are all smiles, and no one has heard of...

💬 Summary

Did you give the chatbot a prompt that impressed you with output? What kinds of things do chatbots do for you that you think others don't know they can do?
