No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Carrying a GPS tracker wouldn't be the smartest thing to do, wouldn't we need someone like Europe or Canada who control their own satellites to assist?

Would this spark the beginning of a space war?

Pagers and ham radio baby lfg

Use radios: Gmrs or Ham

Do not transmit from your base, travel somewhere further away, then broadcast. Change location of broadcast every time.

Use encryption.

One method is using my Rattlegram + SSE method (both open source)

Rattlegram is a mobile app that converts text into audio

You play this audio over the radio, and the other side can use this to decode and get back the text.

All you have to do is encrypt the text using any open source program. I like to use SSE (Secure Space Encryptor / aka: Paranoia Text Encryption on iOS). You could also use PGP, but it would take longer to transmit the message since asymmetric encryption results in longer ciphertext.

Copy-paste the ciphertext into Rattlegram and voila! (Just reverse the process on the other side to get the plain text)

Obviously you shouldn't use any iOS or Googled Android. Use Graphene OS or something like that. Physically disable the antennas on the phones, you need them airgapped.

Alternatively, you can use One Time Pads, although it would be slightly harder to generate, distribute, and store OTPs, but if you use OTP, you wouldn't need to rely on digital encryption, and its more secure, but it'd be much slower to manually encrypt your text.

For resistance radio stations: Shortwave - although there aren't really any interesting stations right now, but if a civil war starts, I could see someone in Canada or Mexico start broadcasting to give the US revolutionaries info. Shorwaves can travel long distances.

Another rgood app is "andflmsg" for Android. It will.let you use a all the common modulation schemes , to transmit text, it can even send images.

it can even send images

Bruh

Imagine transmitting dank memes using a ham radio in the middle of battle 🤣

I'm going to point out, for the technologically illiterate, that GPS satellites do not in any way track people.

GPS satellites go "beep" and by listening to the timing of those "beeps" from different satellites, a GPS receiver on earth can determine it's own location via triangulation. It's a bit more complicated than that, but that's the basic idea.

The only way you can be "tracked via gps" is if your GPS tracking device is also transmitting information using some other method (cell phone, radio signals, non-gps satellite connection, etc.)

[–] LainTrain@lemmy.dbzer0.com 9 points 9 hours ago

This is correct, but that said if you're doing anything Donnie don't like, especially something you'll likely be investigated for, your position can be actively tracked via cell towers, and software backdoors will happily record and transmit your GPS position over the internet, even disabling all this stuff you can never really know for sure, so keep that phone off.

The same supplies of the current communications. Eriksson, Nokia, Samsung.

Look no further then central American drug cartels who built their own mobile network to avoid lawful interception.

[–] kersploosh@sh.itjust.works 7 points 9 hours ago* (last edited 7 hours ago)

GPS devices only receive GPS signals; they do not broadcast any data. So carrying a basic handheld GPS device won't give away your position to anyone else. However, a smarter device like a phone or InReach emergency locating device can relay your location to others.

For communications, lots of people would suddenly get really interested in VPNs and encryption (for using the existing Internet), private wireless mesh networks (for city- and region-level communication), and even amateur radio. Owners of mesh nodes or radios would need to limit their broadcasting time and/or do a lot of moving around to avoid being located.

[–] Idontopenenvelopes@lemmy.world 5 points 9 hours ago (1 children)

NVIS is hard to locate without flyovers. It bounces the signal of the ionosphere kind of like a water hose shooting water straight up . Transmit and reposition. Range is up to 800km's .

Alt flood of meshtastic nodes, without GPS data provide encrypted rebroadcast capability.

Checkout s2underground's project- GhostNet. He's ex military intelligence. https://github.com/s2underground/GhostNet

Is there a ready-to-use meshtastic device? Because they look interesting but I hate to have to build it myself or have to dig around and flash the firmware. I like stuff to be useable out of the box.

T-1000E from seeedstudio

Get the snap hook at the same time. And buy two so you can test it even if there are no others around you

Yea there are some pretty cool ones these days that resemble a blackberry. Checkout the " t-deck plus" by lilygo. The repeater nodes could be cheap solar powered remotes setup at high vantage points, wouldn't need too many to get city coverage given the line of sight , drone drop'em on a couple of highrise rooftops and off you go. ..in theory.

[–] Num10ck@lemmy.world 2 points 4 hours ago

solar powered open sourced boxes on everyones roof in a spread-spectrum hopping mesh with p2p encryption.
