zhynn commented on Bitchat – A decentralized messaging app that works over Bluetooth mesh networks   github.com/jackjackbits/b... · Posted by u/ananddtyagi

I’ve been toying with a concept inspired by Apple’s Find My network: Imagine a decentralized, delay-tolerant messaging system where messages hop device-to-device (e.g., via Bluetooth, UWB, Wi-Fi Direct), similar to how “Find My” relays location via nearby iPhones.

Now add a twist: • Senders pay a small fee to send a message. • Relaying devices earn a micro-payment (could be tokens, sats, etc.) for carrying the message one hop further. • End-to-end encrypted, fully decentralized, optionally anonymous.

Basically, a “postal network” built on people’s phones, without needing a traditional internet connection. Works best in areas with patchy or no internet, or under censorship.

Obvious challenges: • Latency and reliability (it’s not real-time). • Abuse/spam prevention. • Power consumption and user opt-in. • Viable incentive structures.

What do you think? Is this viable? Any real-world use cases where this might be actually useful — or is it just a neat academic toy?

This reminds me a little of [Scuttlebutt](https://scuttlebutt.nz) (positive it has been posted on HN before). But I think these little projects are awesome, even if they have a limited audience. Go forth!

If you love hard-science dinosaur books, I cannot recommend Abby Howard's "Earth Before Us" series: https://www.goodreads.com/series/257878-earth-before-us

They are so so SO good, they have so much care about the science while also being delightfully whimsical and the art is beautiful. Please check them out!

Aren't the solvents pretty nasty chemicals? I wonder how they deal with the sodium hydroxide + sodium sulfate saturated with lignin and hemicellulose... maybe it can be turned into a soap or glue? That sounds like a rough biproduct to have to deal with.

I guess those aren't as nasty as I thought, lye and sodium sulfate are pretty innocuous.

It's probably much less difficult to deal with than plastic byproducts.

> I'd love to know where is considered 'far from civilization' on the continental US.

There are many interpretations and levels of remoteness.

In my case, I want to be away from the sights and sounds and crowds of anything that would be considered urban or suburban. My prime criteria is that I don't want to see another person unless I choose to. I don't want to see a road with cars on it, I don't want to see another house or any other man-made structure that isn't mine. Ideally I don't want to hear anyone else either, but I accept that I may hear things in the distance.

I don't want to be a complete hermit, and I'm not a survivalist looking to be 100% self-sufficient. I want a small-to-midsized town about 30-60 minutes away. Something with a grocery store, gas station, and a post office or other place to receive deliveries. I don't want to be more than an hour away from doctors' offices or a hospital or urgent care. I don't want to be trapped by snow for weeks at a time.

Saying "far from civilization" was a stretch. What I really mean is I don't want to have people all around me. And I don't want to be anywhere near cities and suburban sprawl. I don't want neighbors in any meaningful sense.

Places I'm considering are Maine, Montana, northern Wisconsin, Upper Peninsula Michigan. I would absolutely consider parts of Canada, particularly northern BC. I don't have an easy path to Canadian citizenship, though. Before my Canadian girlfriend passed away last year, we had been planning to look for a secluded lakeside cabin or undeveloped land in BC.

My requirements are dense forest (desert/plains states are right out) and water (lake or canoeable river) on the property itself. I can live with other people using the water, so long as it's not motorboats and a party scene.

My town has about 500 people, but the really active community is about 50-100 that will show up at the various things we do. I am 30 minutes from grocery stores, and 3 hours from boston or montreal. I have fiber internet because the residents got sick of the telecoms and we built our own. And the forest is more dense than Montana (where I grew up), and doesn't light on fire every summer. Please come to VT. :)

Also, I a bought a ramshackle building at auction that I am turning into a community workshop. It will be fun!

I spend four months of the year traveling in an RV. Two years ago, I budgeted over $6000 for my desired solar setup (at least 1200Ah of battery, at least 2400W of solar, plus various controllers and other components). It was expensive enough for me to hold off, and more importantly, I didn't have the space on my current RV for the solar panels.

In just the two years since then, prices on batteries and panels have dropped 25% or more, and solar power per square foot at a good price point has gone up significantly (400W monocrystalline panels can be gotten for $200, in the same form factor as the 200W panels I had been budgeting for). I've now lowered my budget to $4000 for the same setup I was planning to spend $6000 on two years ago, and with 400W panels, I no longer need to upgrade to a larger RV to begin the project.

This summer is almost over, so I'm going to wait until spring to start assembling my system in earnest. Anecdotally, this is a game-changer for me. I'm looking toward year-round full-timing starting next summer, because I can now afford the power I need and don't need a larger RV as soon as I thought I would.

I intend to buy undeveloped land far from civilization in the next few years, and I'm now confident that I can DIY a whole-house solar and battery setup so cheaply that access to mains power won't be a factor in deciding where I settle. Even with seasonal variation in power production, I'll manage just fine, and the system will pay for itself in well under five years. In fact it'll pay for itself instantly if you discount the five-figure cost I would otherwise have had to pay for running a new mains power line far into the woods. And by the time I pick some land to settle on, I'll already have enough solar on my RV that I won't even need to augment the system initially; I'll be able to power a small house in a temperate climate directly off the RV itself, while I build a larger solar array (likely ground-mounted to avoid regulations and insurance complications related to roof-mounted setups).

I know my situation is unusual, but the fact that any of this is possible for well under $10k is a huge change from even a decade ago.

Please come to Vermont, there is a lot of undeveloped land, ample water, and we need people.

I love the feeling I get when I recycle or repurpose something that would have been trash into something useful. Especially if it becomes even more beautiful from its past patina.

This can go too far and put you in a cycle of spending all of your time tending jank (and lowing your quality bar). It's a fine edge to walk. but that pleasure hit that most people get from buying stuff, it doesn't work for me. Buying new things often makes me feel guilty. Re-using or repurposing something though... for me it's one of the best highs there is.

Not who you replied to, but we do this with our kids. The only things are you need are a milkweed patch (there are many varieties besides the big ugly broad-leaf ones you see everywhere) and and a mesh enclosure off Amazon for a few bucks. The process is:

You go out, look for the tiny eggs on the milkweed, bring the milkweed leaves in, wait for them to hatch, and bring in fresh milkweed leaves for food once a day. We put them in a paper-towel-lined baking pan so that they have something soft to crawl on if they wander off to taste-test new leaf. They start out rather tiny and grow to into big fat caterpillars. Eventually they stop eating to go on walkabout and anchor themselves somewhere near the top of the enclosure. (Sometimes they are dumb and you have to relocate them with pins or tape.) Once they emerge as butterflies, set them free.

We do black swallowtails too. They like dill and parsely.

We never get tired of it. We have had 20-something butterflies at a time in a 2-sqft enclosure.

Not sure if the wild milkweed out here in VT is the "big ugly broad-leaf one", but I think they are amazing plants. And I love the alien-looking pods with the almost fractal arrangement of fluff seeds inside. The flowers are interesting too if only because of their brevity, they only last a few days. I love watching the milkweed grow over the summer. Burdock too. Incredible plants.

I wish this article hit on an important point: when should the persistent quit? We all know we should know when to hold and when to fold, but in practice that's a hard decision to make especially when we're invested. And someone who is "persistent" vs "obstinate" should be able to do this: quit when it's right to do so.

The closest thing he mentions is this, "persistence often requires that one change one's mind. That's where good judgement comes in. The persistent are quite rational. They focus on expected value."

Following that, if I'm working on x thing, and the expected value is < some other big thing, I should quit and start the other thing.

But there should be a "grass is always greener on the other side" counter weight - some other thing may LOOK like higher expected value, but that's because you don't know the shit under the hood.

I would've liked him to have touched on this, as I don't think you can truly call someone persistent but not obstinate unless they can actually walk away from something if necessary.

It's a paradox, expertise will tell you which one to pick (know when to quit | never give up). Tom Sachs called principals like these "Paradox Bullets". The movie: https://vimeo.com/293569057

The Order of the Good Death has loads of resources on how to have these conversations, what your options for advanced directives etc. are, and guides on how to set everything up.

https://www.orderofthegooddeath.com/

They also do a lot of advocacy around green burial, alkaline hydrolysis, and whatnot as well.

Caitlin Doughty (who founded the Order of the Good Death) Ask a Mortician channel on youtube covers this stuff too, but the older videos might be out of date.

Thank you so so so much for posting this! I had no idea it existed, and I am so happy that it does.

I also discovered that my home state has ZERO listed green burial sites, which is shocking to me because... I live in VT. I would have guessed it would be the leader in green burial, it is right up our wheelhouse!
