Ask HN: How to engage users in an open source project and when to stop?

melenaboija — Thu, 20 Aug 2026 17:09:21 +0000

I have been working on an OS project for years now, on and off, taking it back up for the last few months and giving it a good boost lately with AI. It has a super niche user base in quantitative finance.

I really enjoy working on it, and although I get contacted every now and then by people who are using it or are interested in using it, and those are really interesting users, I always think I am wasting my time. It has been 8 years now since I started.

I guess my questions are: is it worth it? And I know this question has two clear paths, the personal and the practical one, but I would like to hear from both. How can I know when to stop? If my audience is maybe in the order of two thousand potential users worldwide, how do I validate the idea? I have posted on Reddit and HN multiple times, tried LinkedIn, and that leads me to a handful of super interesting contacts, but I don't know if it is enough to keep going.

Is it a coincidence that the Sun and the Moon look of same size from the Earth?

This is basically a thesis supported by Shannon’s information theory.

Any rigorous CS program should cover this in depth.

The post is a satire and when writing this I see it at #1 of the front page and the comment is #1 too. So I guess you are kinda wrong.

New comment by melenaboija in "China’s open-weights AI strategy is winning"

melenaboija — Mon, 20 Jul 2026 17:39:46 +0000

The US business model for commercializing LLMs seems unsustainable to me. We are saying that they are creating trillions of dollars in value out of:

1. A model that for the most part is public and available to anyone. 2. A situation where the model’s success mostly comes from throwing as much data and computational resources at it as possible.

It seems that either of those assumptions could crumble quickly and unexpectedly. What if the AI paradigm changes completely and we no longer need GPUs? Or what if someone with enough determination decides to create a better model and sell it more cheaply, or free?

I don't know man, this looks scary to me.

This is not shaped like any other IPO. Objectively, it’s the biggest IPO in history and was included in the Nasdaq unusually fast. More subjectively, a significant part of its value is tied to the vision and credibility of a single person. Which BTW happens to be the first trillionaire in the world if things go well.

The other day I asked Fable about fasting for 16 hours, and it flagged my question.

Pathetic situation, this one, where we are supposedly building a superintelligence while at the same time thinking that fasting is a biological weapon.

Not having to use Stack Overflow or Git directly are by far the biggest improvements LLMs have brought to my life.

melenaboija — Sat, 06 Jun 2026 20:18:48 +0000

As much as they don’t, that’s why it’s spying. But given the budget for spying agencies the guess is they might be doing something and it wouldn’t be intelligent not to spy on Israel, something I don’t believe to be true even for this administration.

I obviously don’t know them personally, but what I get from this old school generation that have been a pillar of computer science and, why not, modern human history, is just a tiny little bit more humbleness than “influential” people nowadays.

Yes, which means that in the long run this looks ugly.

So much faith and money in this idea, and seeing how fragile it is, does not look good.

> What if $10 million fine per X AV miles driven is an OK cost of doing business?

It’s the same cost/benefit we accept under current rules. Why have cars that can go 3x the speed limit? Why not require breathalyzers in cars before starting them? Why not fine logistics companies if one of their drivers breaks the law? And so on… Because it’s worth it

That is successful and makes tons of money.

The author is saying it explicitly, you can’t flex as normal people do so you have to feed your ego finding different ways such as anonymous posts. Or talking to an stranger being drunk.
