I think I know why Collatz does that thing it does

Hacker News - Fri, 04/11/2025 - 5:43pm

The normal term for this is "manic delusion of grandeur", so please help me out: 3n walks congruence classes +1 steps each one out of alignment /2 never changes that fact

Accumulating co-primeness is the "memory" that stops n from repeating. This is invariant under 2^k, which allows it to make forward progress through the chaos. Exhausting congruence classes mod 3 forces n to a power of 2; game over.

I asked AI to prove those things, and it did. I assume.

The only question then would be if 1.5n can grow the residue vector quickly enough to outrun the exhaustive walk. I asked AI that too, and got back a one page p-word. I'm not even going to type it.

I can sweet-talk AI into agreeing with damned near anything, so I'm stuck. This is the only forum I know with consistently thoughtful conversation, and I can't think my way out of this one, and I have real work to do.

Is there a mathematician in the house? The p-word is in a comment.

Ask HN: Is using Cursor still coding?

Hacker News - Fri, 04/11/2025 - 5:40pm

When you use AI extensively i.e.: a combination of ChatGPT, Gemini 2.5 Pro and Claude (with Cursor or just "so") - to create something - is this still coding?

Ask HN: How to find good app developers

Hacker News - Fri, 04/11/2025 - 5:34pm

I have an idea for a web based/app based business that will be disruptive to a currently lucrative industry.

I have the skills to do the work in terms of putting together a business plan, and doing market research etc… I even have the skills to do things like wireframes etc and general design stuff (I have an MBA in digital transformation).

What I don’t have is the actual app development skills.

What are some solutions I can use to actually create even just a prototype so that I could create a close to viable product to pitch to investors? And how much money should I realistically be looking to spend?

I’m looking for lots of suggestions that might help me bridge the gap between my actual business knowledge and the technical skills I lack.

Thanks :)
