Hardware hacker who used to do submarine things.

Ecash is OG, it should make a comeback. However, I've always disliked "ethical hacker." First of all, for even the whitest of white hats, hacking is frequently gray behavior. Calling it ethical hacking feels like asking permission to hack something. Which, to your point, they might as well call it "cyber hacker" because it's lame.

There's no ethical plumber and "ethical banker" is equally ridiculous. So I just like to say hacker and let the cards fall as to the ethics. In Slovak, eticky hacker does seem to be the most understood term I've noticed (for me) unfortunately.

But when I'm dressing up, I use "security engineer" which for me, coming from a classic engineering background, is an apropos term I think.

Didn't oura switch to a required subscription model? I like the idea of some of these fitness trackers (although I preferred bands which seem to have falled out of favor to rings and smart watches). The issue with them is what company will eventually have a data breach first πŸ˜€

You finally found your prediction market thing! Will you now just encourage everyone to bet instead of giving their opinion of the future? 🀣

dobrΓΊ chuΕ₯! Any tips on making it? When I cook it it, it comes out less like a soup and more like a stew, and perhaps too salty...

That's the hope :) and this is why people get so into the LoRa rabbit hole. It is, at best case, good for very small messages infrequently sent. In this use case, a radio can run off of a solar cell for years. You can get lora radios for the EU without any license and experiment. It is legitately fun and I'm a big fan, but they have limitations.

Ham radio I'm also into for the same motivating reasons we are probably on nostr :) (decentralized radio etc...) however it does require a license to use legally. Also the ham radio community is a bit frustrating. There are a small number of like minded hams, but most I feel just like to talk on the radio.

So LoRa I think will not transmit voice for example, but with ham radio you could potentially talk globally, directly, by bouncing radio waves off the ionosphere.

In any case, it's useful to pursue if only for the appreciation of how radio works and to understand why not all radio is equal. I've been on again off again with it for many years.

Hopefully that helped :)

Ah sorry. I mainly work in electronics so I forget sometimes :) basically LoRa is this new-ish radio system. It's long radio (kilometers) and low power. It is really ideal for short messages, it was designed mainly for small devices. Because of the frequency it uses, it is essentially available to anyone which is why there is some excitement about using it for decentralized and distributed applications.

However, it does have limitations so it's not a wifi replacement.

Here's a decent, but slightly technical overview: https://www.digikey.com/en/maker/blogs/introduction-to-lora-technology

Idea: Nostr over nomadnet / lora.

For local vexl (p2p btc otc) and nomadic service providers (consultation, massage - h/t nostr:npub1l3e2uj7dzs226s7q9utf9ghml8f3mcv7252hd69nhg2z62updklqv8zq2r or anything else). You arrive somewhere, broadcast a note locally.

Very hard to surveil centrally, but identity and reputation can be kept.

Could be useful as a local relay. Want to meet with nostrich friends? Broadcast a note over the air and only people more or less around you see it.

The idea is similar to truck drivers using radio to snitch on the locations of cops, or traffic jams.

I think you are really under appreciating the bandwidth limitations of LoRa... This will work if maybe there is one person sending announcements but LoRa is not WiFi. That being said, WiFi mesh with directional antennas would be fine.

However there is a project, but limited to typical ham radio restrictions called ribbitchat. It's pretty amazing actually, you hold your phone to a radio and it transmits the message :)

Are you posting this with a nostr private key supporting hardware wallet? Would you if you had one? (I think foundation wallet is considering support). I don't disagree with your comment but I think someone's reputation might be worth more than their stack and we all seem ok with private keys in our nostr clients.

I'm not sure I really want to constantly interface to the internet with two Turing machines, where one is just approving the requests of the other. But maybe that's needed.

If you wear a smart watch, the watch takes care of you. But if you wear a automatic mechanical watch, you take care of the watch.

I gave a talk about an introduction to computers security to a bunch of electrical and electronic engineers. I recorded a version here: https://cryptotronix.com/2023/07/24/free-the-cpu-an-introduction-on-how-hackers-liberate-computers/

I'm pretty sure there are still many places in the US where the recycling goes to the landfill. This is basically the cargo cult behavior -- maybe one day it will be recycled so if that day comes their behavior doesn't need to change.

It was less a generalization and more anecdote, of which, my jaw dropped. Yeah, the route issuer is the obvious first thought. But I'm not sure the solution is the one everything box. If you reboot your AI-router-node-nas-wallet-mediaplayer every night I'm not sure that's a great experience.

Then, once you do have that one everything box, the next issue is backups, reliability, etc...

I'm not trying to be over critical. I spent a decent amount of time noodling a node like solution but when you put the dollar sign next to performance hardware to do all those things, its not as affordable as consumers would like.
