You can already do that without being a trusted device.

For the longest time, you couldn't. It wasn't until this release I realised that had changed. If it changed before, it wasn't well communicated to me as an Android signal user. I was on beeper and then molly precisely because there was so little traction on changing this. You could install signal fine, but you couldn't QR code or secret phrase mesh it with your android handset. Oddly, iPad meshed fine with iPhone or…

Definitely under 18 months.

If I’m not fully mistaken, I checked for the combination of iPhone as main device/Android tablet as iPad-like second device sometime in the past six months, at most since the beginning of the year, and it wasn’t possible (unlike phone + iPad as tablet, which seemed quite strange to me).

In any case, it’s a recently released change.

> And yes, using a VPN will get you knocked up as well. Well, damn.

For reference: In Britain, and presumably India: "get you knocked up" = "get your door knocked on". In the US: "get you knocked up" = "get you pregnant".

In Britain it means get you pregnant too.

OpenAI is 501c3, should they also be required to release everything?

OpenAI is a 501c4 not a 501c3. Also the structure is much more complicated for OpenAI. Nevertheless the point stands - I don’t see what relationship company organizational mission has with their technical responsibilities. Indeed, if the open sourced everything, standing up a clone would be easier which creates funding risk due to a race to the bottom of people who didn’t invest into the R&D investing very little add…

    > OpenAI is a 501c4 not a 501c3
This is incorrect. OpenAI is actually registered as a 501(c)(3) public charity, not a 501(c)(4) social welfare organization. (Source: Bloomberg Law)

    > Also the structure is much more complicated for OpenAI.
However, this is correct. Their corporate structure is very complex. Here is a screenshot from OpenAI's corporate structure explanation page (now taken down): https://images.axios.com/fbMDxci4KDAoYxM_v61sPi9jSVs=/0x0:19...

Ugh wtf so I need a Google account on Android? That's not going to happen. For an org that pretends to care about privacy you'd imagine there'd be a way to avoid, you know, the biggest privacy invader on the planet. Just allow monero payments or something. Alongside Google play for the sheep that want to use that.

Are you being hyperbolic, or do you really consider Google the worst with regards to privacy.

Google is objectively the worst

Signal is there for power and control, not for its users, otherwise they would welcome the usage of third party clients, and generally, encourage decentralisation measures like self hosting, federation and account portability. Yep, they have nice engineering blog posts, they are also US-incorporated, extensively centralised in AWS and subject to the cloud act, which together negates, or largely diminishes claims abou…

Does the perfect messaging tool exist (100% e2ee encrypted and decentralized and open)?

Is there a messenger that allows anonymous group chats, i.e. for union organizing in a company?

As far as I can see, you can invote people to a group chat using QR flyers, but your Signal profile is visible to everyone in a chat, so everyone knows what Tina in marketing thinks about it.

Because nobody is going to have a burner phone with a data plan for a separate Signal identitiy.

Signal needs to release all the infra automation code behind their backend. How they setup and manage it all should not be secret. It also makes it easy to rebuild if for some reason they are compromised. They've ghosted multiple people about this question. There's no reason a 501(c)(3) shouldn't release it.

Why would the CIA bother?

any link to presentations/papers on this? I'm interested on learning ZKPs -- they seem so much like "fairy-tale come true" because I don't know much

It's standard cryptography, not some new-fangled tech! Wikipedia even has some easy examples: https://en.wikipedia.org/wiki/Zero-knowledge_proof Main caveat is that ZKPs are probabilistic. The protocol (number of rounds etc) determines how sure, e.g. 99.9%. But never 100%. Second caveat: tech- and crypto-bros play fast and loose with the term "ZKP", either because they don't know any better (marketing) or they straig…
