Thanks for the links, very interesting.

That has been my feeling too. I have completed soo many personal projects (or improvements) that were collecting dust on my 'mental shelf'.

Without AI I would probably never get to them because realistically, I do not have dozens, or hundreds of personal hours to devote to fun, but unnecessary projects.

Well it is subtle satire done well because another person could write the same thing and be completely serious.

Yes a bit ironic, but I am glad they can see that there are times to use AI, and times for human interaction.

How can one downvote on HN?

Show HN: LLM-DAG-UI – A branching conversation interface for Claude

tenahu — Thu, 12 Feb 2026 12:55:11 +0000

I built a proof-of-concept UI that displays LLM conversations as a directed acyclic graph instead of a linear chat.

Try it: https://llm-dag-ui.vercel.app (screenshot in repo)

The idea: conversations with LLMs often hit dead ends or go in directions you want to backtrack from. What if you could branch off from any message and explore a different path, while keeping the original intact?

How it works:

- Drag from any message node to create a new branch.

- Each branch only has context of its direct ancestors – it doesn't know about sibling branches or other parts of the tree.

- Delete a node and all its children disappear with it.

Useful when you want to try three different approaches to a problem from the same starting point, or test how Claude responds to different phrasings. This is a concept demo, not a polished product.

It uses BYOK (bring your own Anthropic API key), stored only in your browser's localStorage. The Express proxy just controls which Claude model is used; your key passes through but is never logged or stored. Nothing persists between sessions.

I think this is closer to how LLM conversations should work. The linear chat paradigm made sense for messaging, but exploration is rarely linear.

Would love feedback on the interaction model.

Show HN: MoonLocator – Astronomical library for moon calculations in Java

tenahu — Mon, 02 Feb 2026 22:03:40 +0000

I extracted the lunar calculations from my Android app Lunar Locator into a standalone Java library.

The equations are from Jean Meeus' "Astronomical Algorithms." Given a time and location, it calculates relative lunar positions, rise/set times, distance, illumination, and more.

Available on Maven Central (Java 17+): https://github.com/dgrims3/MoonLocatorLibrary

Happy to answer questions!

Yes, I was wondering if I missed some context.

New comment by tenahu in "Chuck Klosterman on why we've never actually seen a real football game"

tenahu — Tue, 27 Jan 2026 20:29:01 +0000

Interesting, and I have also finished live football games thinking it would have been better to just watch it on TV at home.

However, his claim that a spectator would "automatically reframe what she saw into the way it would appear on television" is never supported other than him saying "trust me, it's true, if you don't believe me you are in the minority".

I think that depends on how you interpret "happiness to become one’s default state of mind."

I think feeling happy is my default. I still get mad, hurt, sad, bored, etc. But when those feelings wear away, I return to a general state of happy contentment.

This sounds interesting, but I do not totally understand your description. Could you explain further what you are building?

Ask HN: Needed Skills for Micron Workforce Hub?

I have seen in the news that Micron is receiving $6 billion to invest in a Syracuse factory. What skills are in demand for a factory like that? For context, I am a SWE without much hardware experience.

Software should not be free for the users. The expectation that profits must be made through advertising, paired with the entitlement of users who scoff at the idea of paying for a product is a recipe for disaster over the long term.

That was my same thought. This example would only work in specific circumstances, so why present it as a rule,
