Selfhosted

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Briar is a messaging app designed to be used by groups of people to allow for secure and censorship resistant communications.

This technically isn't self hosted in the strictest sense but I think it is still relevant.

Messages are only sent when both online though

That's an entirely different thing, yes. πŸ˜„

I've always wondered what the utility is in sending messages over Bluetooth. Exchanging data secretly and securely in person, I guess?

No one else then the parties messaging can see that the communication even occurs.

Right, but you have to be so close to each other for Bluetooth to work.

It transfers across other peers; you don't have to have a direct connection to the recipient, just an eventual connection to them.

But you have to directly connect to other people's devices via Bluetooth along the way, right? Like a relay race of handing over the message until you either reach a network, or the recipient?

[–] TheButtonJustSpins 1 points 4 days ago (1 children)

I.. don't actually know. I wouldn't think that would be necessary (at least manually).

[–] victorz@lemmy.world 1 points 4 days ago

If not, it goes against everything I thought I understood about Bluetooth πŸ˜† Curious to know how it actually would work.
