A decentralized peer-to-peer messaging application that operates over Bluetooth

For Portugal the "free" healthcare is extremely generous to anyone staying there, regardless if citizens or not. It does lose money, but then again Germany always pays the bill.
Back of the envelop calculation: Portugal gets about 33 “Kampfpanzer Leopard 2” worth of money from Germany via the EU. If this truly finances universal healthcare in Portugal for everyone, the Portuguese should run the world.
Salaries are low and equipment/infrastructure is top notch so the overall deficit per year is about a billion EUR, which is the extra they deduct from our taxes and Germoney. Quality and efficiency of "bang per buck" is decent albeit citizens always complain.
Portuguese did run half the world for a couple of centuries, the most spoken language by natives on the southern part of this planet but quite tiresome to deal with all that, now is more like Italy and prefers quality of life.

I don’t take concepts as a 'full package'. I evaluate what is worth taking based on the requirements. The brilliant part of FidoNet is the asynchronous persistence. In a 'sea of supercomputers,' a real-time mesh (like Bluetooth) fails because it requires an end-to-end path right now. Store-and-Forward allows a node to hold a message until it 'sees' any valid peer, turning every 'meat-bot' into a mobile post office. M…
Yes. There's a lot of things to work out. Here's one scenario: Node A has a message to send to node H, but A is disconnected (no peers). Node A stores this message for eventual delivery. Eventually, node K (ie "any valid peer") appears. Node A gives them the message that is intended for node H and rinses its hands of it. Does node K's possession of this message actually improve the odds of node H ever receiving the m…
In theory, yes. There are now two nodes with the message for H.
In practice? A and H might live in the town and K might be just visiting for business, they might never come back.

#344It's criminal that cell phones are bristling with incredibly advanced radio technology and yet they are by law not allowed to communicate directly with each other over a distance of more than a couple hundred meters without assistance from a licensed and centrally controlled base station. Meanwhile a $10 walkie talkie using primitive stone-age radio technology can go many miles with zero infrastructure, but by law is…
I’ve been tangentially involved in experimenting with Meshtastic and trying to scale it for large events like Burning Man, on the order of 2000–3000 nodes on a single frequency. Node to node mesh communication is cool and it works surprisingly well at small scale, but the moment we brought high powered repeaters online the difference was night and day. Coverage, reliability, and usability all jumped instantly. It mak…
On the other hand a "high powered repeater" for Meshtastic is just the same board with a bigger more optimised antenna.
You can get solar powered ones for under 100€ and slap them wherever you want pretty easily. (But please don't unless you know what you're doing, adding useless router nodes makes the network worse, not better)

HAM radios can transmit data I think. They just can't do encrypted transmissions. (I'm open to correction on this.)
They _can_, they're just not allowed to. It's a tradeoff, they can use higher transmission frequencies than regular folk, but also have to do it in the open.

From white paper: >At its core, BitChat leverages the Noise Protocol Framework (specifically, the XX pattern) to establish mutually authenticated, end-to-end encrypted sessions between peers.
I actually wrote a Noise implementation and someone wanted to make a Bitchat implementation with it, but my impl only supports BLAKE2B (and I got the impression this person really didn't know what they wanted to do in the first place). It's kinda sad more haven't moved to BLAKE2B (or BLAKE3, which I almost never hear anyone talking about).
Wasn't BLAKE2s recommended on the Noise mailing list, being faster for low volume messages, even on 64-bit?

Home market for iPhones is the whole world.
In India IOS has 4% of the market share of mobile devices whereas Android has 96%. https://gs.statcounter.com/os-market-share/mobile/india
Sure, that is still millions of devices. What about other countries?
Home market would imply one country, but given there are billions of iOS/Apple devices throughout the world, this is not really a valid argument to make.

> wish I had fuck-you money and could spend my day engrossed in whatever I find interesting A good mental exercise is to calculate how much you'd need to survive indefinitely in a pocket of rural America or the third world.

I've never seriously considered this, but that's a sobering realisation that most of these numbers are more achievable than most think.
Thanks for the inspiration, I should run my numbers as well.

Coll idea. One thing: This numbers exclude healthcare costs as you get older this gets more expensive. For countries with free healthcare, it is usually limited to people working there or citizens and ( in the German case ) recognised refugees.
In Taiwan you can be on NHI within 6 months of arrival on certain visas. Once you get permanent residency, you're always eligible so long as you keep making monthly payments, which cap out at around 45$usd/month. NHI makes an MRI cost less than 100$ usd. If you don't have NHI you can pay iirc 300$ for an MRI, 100$ for an emergency room visit with blood draw and IV, maybe ~30$/month for buproprion over the counter.

I thought fuck-you money also included the ability to explore whatever you want in a way that included e.g. hiring a team to explore projects for you as startups?
Also everyone I know with fuck you money already lives in Asia for cost of living reasons, but spends half the year jet setting to various raves and rich people shenanigans in random places like Croatia.
