Or perhaps require webcam and do eye tracking?
Is there a way to detect this approach?
Ask HN: What are the algorithms used by predictions markets like Polymarket?
I am curious how prediction markets like polymarket and kalshi work behind the scenes. I assume it's more like stock options than sports betting.Is there something like a market maker to help provide liquidity?Is it setting probabilities/prices using something like black-scholes?How would you design a very simple prediction market MVP?
But not sure how applicable to agencies it is so YMMV.
Show HN: I made a weight-loss app using OpenAI APIs

Hey HN, wanted to show you my weekend project (several weekends actually).A few months back I started experimenting with LLMs as a way to estimate calories/macros and give useful feedback. The results were good enough that I felt like something was there. I wanted to shed a few pounds so I built out a web app for myself. A few friends tried it and everyone said "this needs to be a native...
If I needed more dense data viz (ex a datadog-like system) I'd probably go with something D3 based
Aside from the obvious question of "how are you different/better?" I'm most curious to know why you're going so broad initially. You've got everything from legal to devtools to gaming. Seems like the opposite of a wedge/beachhead approach. Why?
Regarding the monthly scale mentioned in article–we are way beyond that now.
A lot of really smart people worked on this and it was fun to watch unfold.
- In my chipotle bowl, it can tell if I had brown rice vs white rice
- In my In-n-out, it can tell if I got it protein style
It struggles with accurate weights/volumes but I'm excited about where this is going.
1. Analyze calories/macronutrients from a text description or photo
2. Provide onboarding/feedback/conversations like you'd get from a nutritionist
My stack is Ruby on Rails, PostgreSQL, OpenAI APIs. I chose Rails because I'm very fast in it, but I've found the combination of Rails+Sidekiq+ActionCable is really nice for building conversational experiences on the web. If I stick with this, I'll probably need a native iOS app though.
Vendor stack is: GitHub, Heroku (compute), Neon (DB), Loops.so (email), PostHog (analytics), Honeybadger (errors), and Linear.
My hypothesis is that, if you could drive traffic to your site and offer a fast checkout experience, there's probably multiple ways to monetize that. Driving the traffic is the hard part.
Here's a pro tip + feature you should implement: Shopify has a semi-hidden hack where you can link directly to checkout of a product if you know the variant ID. You could add a BUY NOW button to your site without forcing the user to navigate the original site or checkout flow. Example: https://hapaboardshop.com/cart/42165521907955 (it also supports quantities and coupon codes)
A word of caution: more products isn't necessarily better. I definitely found there to be a long tail of really bad shopify stores and products. IMO it's better to curate or audit the stores you index–otherwise you risk your site being littered with kitchy t-shirts or drop-shipping garbage.
I think you could get consumers to subscribe to discounts/deals at nearby restaurants and I think you could get restaurants to offer discounts one-time or during non-peak days/times. I tried to do this in the past using card issuing services (like Stripe's) but it was clunky with debit cards. The ability to do this via credit would make this a lot easier.
I live in a California town called Arroyo Grande ("big creek")
Couldn't the why be due to (at least in part) these innate gender differences?

If you want to come work at a big tech company with a genuine mission (literally "Help People Get Jobs"), come join me at Indeed.
As part of an effort to dogfood our own virtual interviewing products, our Enterprise group is holding a virtual hiring event next week (Sept 8) for software engineers at various levels. If you're interested, please reserve a spot here:
https://intsignup.indeed.com/interview/3c1f9569-c8c0-40c2-b2...
I also have UX, engineering manager, and data/product science roles open in my product group. If you're interested in those roles, please email me directly: [email protected]
Cheers!
I lead engineering for a product group devoted to deeply understanding jobs & job seekers–and then surfacing the best candidates to employers. One of our teams was a YC startup acquired in 2017. If you're looking to work remotely at a large tech company with a genuinely positive mission and great work-life balance, then please keep reading.
We currently have several roles open across 4 teams, including:
- 1 Engineering manager role
- 1 Senior UX designer
- 1 UX researcher
- 2 Staff/Principle engineers (10+ yoe)
- 1 Product scientist
I encourage anyone here who is interested to email me directly: [email protected]
Tech stack: React, Java (Spring), Kotlin, PostgreSQL, Redis, ES, AWS, k8s, Elasticsearch, Ruby on Rails
For a large tech company I find it extremely impressive how much everyone at the company–from senior leadership to L1 engineers–sincerely believe in the mission and what we’re doing.
I’ve got several openings on my team. I’d encourage you to read more about our values. If it aligns with what you care about feel free to reach out.
Few products have made our personal lives so much easier. Not having to ever get/give cash for them is amazing.
This could be a way to do the right thing while lowering your risk of being charged with violating some antiquated hacking law.
But also talk to an attorney before doing that.
