A couple of weeks ago I was listening to a conversation with Elon Musk where he mentioned something that stuck with me. At Tesla, they don’t run every possible simulation. They focus on the ones that produce real signal. The branches that generate learning. The boring ones get pruned because they teach nothing. That idea kept rattling around in my head. If we take the simulation hypothesis seriously (as he does), maybe the same applies more broadly: only timelines that produce learning are worth exploring. The ones where people take clear positions, make bold calls, and are willing to be…

Existential▲84As the end of my fixed term NHS contract approached, I did the sensible thing and started interviewing for my next product manager role. Then something clicked. I’m 29 with no dependents, have a modest amount of savings, and I’ve been dreaming of my route back to the startup world. I’m not saying this is my last chance, but it feels like a window of opportunity. There’s a lot of debate on side hustling vs a full time ‘burn the boats’ approach. After a couple of years of the former, I’m ready to try the latter. (Though in my case it’s a ferry, and I don’t think CalMac would appreciate me…

FoundersWall▲35I used to be just a blogger. Now I build internet products, still without code, using AI, design, and taste. I was building in public on X for last 2 months. And honestly, I got tired of how it became performative and started to feel fake. I shipped 2 products. Both failed to get any real traction. I kept sneaking into popular builders’ profiles, hoping to learn how they do it. One thing I kept seeing everywhere, product launch directories. I thought here is the scope. So I started building one. Same UI like the rest. Nothing special. Suddenly one day when it was half built, I realized…

Hey HN! I’ve been building Fatebook for the past couple of months. It’s a slack bot to help your team make and track predictions, right where you work. I see forecasting as anti-bullshit technology: - It gives you truthseeking incentives - You communicate your uncertainty as a probability, which is way clearer (70% is better than “probably”) - You can aggregate forecasts to get wisdom of the crowd effects - You can see everyone’s track record, and pay more attention to people who are consistently accurate I’m a fan of prediction markets [0] and forecasting platforms [1]. But predictions on…

Hey HN, We explored how decision-making happens under severe information asymmetry and used career exploration as a test subject. In practice, people converge on a small set of highly legible default paths, with little visibility into credible alternatives. That’s why we’re building Fig, a tool for reasoning about career paths when the next step isn’t obvious, given the dependence on fleeting personal preferences. Most existing tools respond by collapsing uncertainty into a single recommendation or by modeling careers as linear trajectories. That works reasonably well at the recruiting…

I built a web page that aggregates data about data center buildup, sovereign fund investments into AI and bottlenecks. The objective is to predict AI race cooldown by looking at a potential decrease of activity involving these elements. The website looks at the quarterly forms from the 5 biggest hyperscalers and adds their CapEx into the mix, calculating a composite index in the end showing how likely it is for the AI race to slow down. Enjoy!

Hi there, I've decided to jump on the AI train and put something together with low effort & high reward, to see if it can get any traction. What do you think? Is it a promising area? Do you guys have ideas for me? There is obviously going to be sea of LLM generated content out there and one project adding up to it might not necessarily be what world needs. In the same time there is something intriguing about the area. Well, please play with it and let me know what y'all think. Much appreciated.

I've been working on a platform that uses LLMs to turn any random idea into 2-3 minute episodes - one of the newer ones is JARS Tank, where you can pitch inventions to a panel of AI investors. Would love to hear your thoughts!

Hi HN! I spent the last year traveling and feeling purposeless after shutting down my last startup (Zage YC S’21) in Dec 2022. There were some obstacles I couldn’t overcome and decided to return investors 50% of their capital. To afford (and justify to myself) traveling, I started consulting as an engineer and product designer. I started (https://backspace.nyc) and it was a good time. I (and some friends) built a handful of AI experiences and learned a lot along the way. The hardest thing about running a services business shipping and selling AI experiences powered by LLMs was…

b4zero▲7It started out when I thought about how to help founder to validate their idea, not just coming up one but how to turn the idea into real business by not relying on AI but making them more involved into their product, understand the market by doing research, check what user want. It's like a checklist, a step for someone who want to get start. This is not an AI to go tool, it's a tool to drag user back to reality, simple but important. I don't think I'm gonna make money with it so I decide it will be a free to use. Use referral code "beyondzero" to sign up. Thanks

I made a lightweight web game about compute CAPEX tradeoffs: https://darios-dilemma.up.railway.app/ No signup, runs on mobile/desktop. Loop per round: 1. choose compute capacity 2. forecast demand 3. allocate capacity between training and inference 4. random demand shock resolves outcome You can end profitable, cash constrained, or bankrupt depending on allocation + forecast error. Goal was to make the decision surface intuitive in 2–3 minutes per run. It’s a toy model and deliberately omits many real world factors. Note: this is based on what I learned after listening to…

I built this simulator to study how simple trading agents interacting with an order book can create emergent patterns—volatility, clustering, even chaos—without any external shocks. It’s meant as both a research toy and teaching tool. You can run different strategies, adjust configs, and watch dynamics evolve. Curious to hear feedback from the HN crowd on features/dynamics you’d like to see added.

I am working on this because I am always afraid of building things that people don't actually want. I let agents role-play analysis the idea, quote and debate with each other. Still working on the output quality, every feedback is priceless. Pls try it out!

Hello HN: I love the randomness of the universe. I've been spending some time creating a Craps simulator to help experience this love without having to shell out like a real degenerate. For others similarly fascinated: I would love to hear any and all feedback you've got on this. It's meant to be unique in the sense that it's a community-oriented, infinite simulation.

Hey HN, After GPT-3 created waves in the tech industry, a lot of AI tools were emerging and with that, some AI website builders But the results seemed way too generic to us. It felt like the developers were rushing to catch the wave instead of building a proper tool We took our time, did months of RnD and finally came up with something better than what others in the market are doing. It’s got better design output. While it’s still in beta, I wanted to show HN what we did. Will appreciate the feedback when you guys try it out. Here is the link to signup for the beta:…

A friend and I are launching an alpha first thing in 2011. We're trying to gain some momentum and whatnot, so we're opening early registration as of tonight. We're planning to develop a Bayesian network to derive suggestions. If you're interested in seeing our progress, check it out. Edit: Any and all suggestions, criticism, advice, etc is highly appreciated!

Finding the balance between humans and machines has been the thread through my career. I always had a thing for AI and couldn't wait for it to actually deliver on what was promised. Now it does, and it's more important than ever that humans and machines keep working well together. AI makes creation trivial. Text, code, design, strategy, in seconds. But one thing AI does not create: independently verifiable proof of when something existed. Reproducing is now cheaper and easier than creating. Chronology becomes contestable at the moment it matters most. The universal problem was known. I…

I’ve been working on a browser-based evolutionary simulation as a personal experiment. Organisms adapt to environmental pressure over time, and there are no explicit goals or scoring, the system is open-ended and runs continuously. I built this mainly to challenge myself and to explore how to surface simulation behavior and statistics in a way that stays readable rather than overwhelming. As a side effect, it’s also something my kids enjoys watching run. Curious what resonates and what doesn’t, and happy to answer questions about the design or tradeoffs.

Now that Wikipedia has banned AI generated articles. - https://en.wikipedia.org/wiki/Wikipedia:Writing_articles_wit... I wanted to try and see if it was possible to get somewhat decent engine based on signs of AI writing from wikipedia themselves. It runs entirely in the browser via WASM. Added instructions to further add more ways to figure out as we find out more about LLMs. Would love feedback!!, especially: - cases where it completely fails - patterns you think are stronger indicators - whether this approach is even worth pursuing vs proper ML models, considering this…
