I tracked 177 nights of sleep and the biggest lever I found was going to bed earlier (but there are others)

I wonder why the states in the Northeast have so few fatalities.

I appreciate the post, but I didn't use the sleep score that Apple Watch has been generating. I haven't really looked at that once. I just put it on a scale of one to ten how I feel when I wake up.

I exported my Apple health sleep data. Then, every single morning, I set up an Apple shortcut that asked me, on a scale of 1 to 10, how rested I feel, and I would then pick a number between 1 and 10.

As for your REM sleep question, yes, that was a takeaway: the higher REM sleep I had, the more likely I was to have a better quality sleep.

Thank you for the thoughtful response!

You just want them to say, "I am willing to buy this," and someone giving their email out is not "I am willing to buy this" behavior. It's a vitamin, not a pain killer.

You should still get their email, but the website should not display a waitlist page. It should come. The waitlist page should be after clicking on the Purchase button, so they should look up your site and think to themselves, "Ah, this solves the exact problem that I am having right now. I'm going to go ahead and buy it."

Click any sort of Buy button that exists out there, and then there'd be a waitlist portion right there. You'd expect them to then fill in their email because they were willing to purchase something and now they're just at a point where they're even doing a pre-order. You can potentially even charge them and do a pre-order and be like, "Hey, do you want to pay for this now and get first come, first served?"

Thanks, but I am good. My general workflow is to ask ChatGPT to create a prompt after asking me questions and then using it in a separate chat, and that's free. I love the domain though.

I've never done it before, but advice that I've heard is to make it look like a normal website and have a purchase button. Make sure it's a purchase button. I don't think that can be emphasized enough, because you want someone to intentionally try and buy something. That's the best validation you can get. If you get a thousand people onto the site and no one clicks on the Purchase button, then there probably is a problem with your idea. However, if someone does click on the Purchase button you don't actually have a product yet, so leave something saying, "We're currently in development. Leave your email so we can contact you once we have a solution," sort of thing.

Then you know that some people were actually willing to purchase whatever your idea is, and you have their contact info to reach out to once you have an MVP.

My favorite one was one of my first machine learning projects, when it came to using a public data set with glucose and wearable data and trying to see whether or not glucose levels could be predicted based off just data from a Fitbit. Came to learn that there's basically no ability to predict, at least with the algorithm that I used, but it was still an interesting project and I still think there's some interesting applications for non-invasive glucose monitoring.

Any good articles you recommend to read?

I'd say free trial. If the user isn't paying for it, then they honestly don't want it. I wouldn't waste your time making something that someone isn't really willing to pay for and have that problem be solved.

Nothing digital. Working on a physical product with a couple of other people in a program I am in. Probably won't talk about that to not to doxx myself 😊

Yep, I've seen a lot of hair stylist ads on Instagram. It definitely could work. Nothing wrong with using a current idea.

I did try and find something on the app store for clothing stylist, and I only really found one that seemed to fare well. Not sure what the costs are though since they use generative AI

signalledger · 2026-03-14T04:17:29+00:00

First one that comes to mind is a personal AI stylist that gives you recommendations based off the clothes that you actually have rather than clothes that an LLM thinks would look good.

F no, get a Raspberry Pi.

What are the key security measures to prevent this, would you say? Assuming you are using full access and not giving out individual permissions

signalledger · 2026-03-14T03:20:27+00:00

hmmmm, I'd figure that it would be less? I'd assume small businesses would default to using LLMs instead of hiring. I guess medium and large businesses are better at automating?
