Hoje recebi de uma tia - a tia inteilgente que me manda essas coisas antes de retransmitir - um vídeo difamando a Natalia Pasternak.

Coisa para lá de hedionda. Totalmente sem escrúpulos. Desde o formato que parecia um trailer de filme de terror, até o conteúdo onde fatos eram distorcidos até darem a entender o inverso do que representam.

Bem, vim aqui só vomitar isso.
Boa tarde para todes.

Overview of the decentralised Hubzilla Social Network

Watch an overview of the user features as well as admin features for the decentralised and federated Hubzilla social network. Hubzilla can be considered a worthy alternative to Facebook, and it has a unique feature for cloning its channel elsewhere to act as a live backup in case the primary hub is no longer available. It has posts, photos, events, calenders, chats, wikis, webpages, and plenty of 3rd party add-ons.

Thank you very much for this video @GadgeteerZA

This is a great video, but he makes a mistake when talking about the secrecy of content. Unless you add extra encryption through a shared key, for which you have to enable the "Even more encryption" Editor feature, the server admin does have the possibility of inspecting the contents of messages by querying the database.

@Alexandre Hannud Abdo Yes, in the early days any non-public post was obfuscated within the database. That was later droppped for performance reasons.
I'd love it to ve back as an option.

They weren't only performance issues, it broke search in private posts among other things. And in any case it only put the admin a function call away from reading whatever they like, while giving a false sense of secrecy. Moreso since your message will typically be copied in other hubs that make no such guarantees.

Interesting discussion... I was thinking about privacy of Hubzilla myself, lately.
@Alexandre Hannud Abdo

And in any case it only put the admin a function call away from reading whatever they like, while giving a false sense of secrecy.

How does this work? Would the admin not have to have the decryption key to do that? Or do you mean that the data has to be decrypted on the server to be sent to the browser, so others can listen to it at that point?

But that would mean that E2EE is no real benefit even now, and we basically entrust our personal communication to unknown admins of all federated hubs, even if we operate our own... Which is better than to send it strait to data selling companies and governments, but what should hinder those to do operate and monitor an own hub?

Just trying to understand...

@Witcraft As the system needs to decrypt, the keys need to be accessible and readable to the system. Your channel's key is also part of your backup json file if you backup your channel profile. It's tied to your channel, saved in the database.
Therefore I did call it only obfuscation on purpose.
There is an addon that enables real E2E encryption. There you need to find a way to communicate the password to the other party, it's separate.

The main contribution of the two specifications OpenWebAccess (OWA) and Zot is that OWA does cross-domain authentication while Zot does cross-domain authorization, both of these should happen over encrypted HTTPS transport.

While the transport over insecure channel is encrypted, the messages or content sent inside the encrypted "tunnel" are not encrypted before going into the tunnel, and thus are not encrypted when they come out at the other end. OWA and Zot will ensure recipients must prove who they are and that they are allowed to see the unencrypted message once received.

End-to-end-encryption (E2EE) adds encryption of the message before transport, which requires decryption after transport. You may think of it as an armoured car with gold inside a secured tunnel.

The app you must add to your editor displays a key icon. If you add something inside the editing window, and then press the key, the content will be encrypted in your browser before transport. This is done using JavaScript using the standard encryption algorithm AES 256-bit, which is very good.

To decrypt, a shared key or shared password is needed once the encrypted messages reaches the recipients browser. Again, JavaScript is used locally in the browser to decrypt it, not on the recipients hub where the admin can see. This shared key or password can be provided as a hint only the recipient knows the answer to, or it can shared outside of Zap and Hubzilla, thus no hint is needed, but can be given for fun. An example of the first is "Paris is in..." and an obvious answer is France, but it could be "... in love with Helen".

@Haakon Meland Eriksen (Parlementum) Thank yo for that full explanation. My last doubt in that matter was a possible server-side en-/decryption. With Javascript client-side en-/decryption, this is wiped off the table.

I keep in mind that most standard forum software uses unencrypted database entries with a permissions system to store your personal communication (PMs). Still, it is good to have E2EE at hand for more personal communication when all posts are released into an incomprehensible network of other servers. Plus, there is the option of keeping information local for controlled access if we use other formats (other than social posts). The more I learn about Hubzilla/Zot, the more I like it :)

Plus: I enjoyed the fun appraoch to passwording idea - thanks! :)

As for passwords: There is an old indigenous memory technique to sing important information. That does works brilliantly for me. I write a memorable line, set it to a melody and depending on how successful I was and if I could do it mindfully I may even not need to look it up even once. And that is despite it no longer being a password but a passphrase of 20-30 characters, or more.
To me that ancient knowledge rings very true: if you can sing it, you'll remember it. I sing about whatever moves me at that moment, can be the beauty of a tree, the desire to get some sleep, being pissed at something, going for a picnic on the moon, meteor jumping with my bike ... that way I put emotion into it, which makes it even more memorable, or a place I have been / would like to go / invent. The more dimensions that phrase has got, the easier it will be to remember.
The fun thing: this is some fun just for yourself, nobody may ever get to find out what you are doing. You are very free to invent.
