simplex-chat VS Nextcloud

For messaging I'm currently on Olvid (E2E with physical key exchange) but since it still use their servers, I'm currently testing SimpleX where I can host my own servers.

Notice how SimpleX (https://simplex.chat/) has no push notifications by default because of this issue.

I've been using SimpleX [0] with a couple of friends recently. It appears to work as advertised.

If you have a mobile phone number, the domestic intelligence agency knows exactly where you are at all times and any LEO (without a warrant) can also find you. In addition, there have been numerous CCC presentations showing how insecure the global (excluding US) and (separately) US carriers are guilty of promiscuous metadata trafficking ($$) and insecure SS7 setups. As a consequence, for low $, you can go to any one of several shady websites and find the last location of almost any phone number (person unique ID) globally. There are additional varying exploitable vulnerabilities depending on the exact combination of {handset x carrier x country} to impersonate them, tap their line, reveal their exact location, and redirect their phone number through a third-party handset or even a PBX. These are more expensive and some capabilities are forbidden for all but a few selective intelligence uses.

Session (Signal fork) doesn't use phone numbers. It's pretty well-designed overall and uses an onion routing approach. It's already a superset of Signal except it doesn't use phone numbers. https://getsession.org

PS: Using regular TOR on home broadband or cloud servers is relatively risky and inefficient. Sybil attacks on it are common. And to network operators and security agencies it gives an easy "flow tag" of your uplink and exit node data traffic as automatically suspicious.

It really is hard to leave Gmail when all of your data has been conveniently stored therein. This is one of Google's retention strategies and it is indeed brilliant.

That said, there's a vast number of self-hosted alternatives like Stalwart Mail (email) [1], Immich (images) [2], NextCloud (Google Docs) [3], etc.

NextCloud - GitHub

Good open source self-hostable alternatives exist! https://nextcloud.com/ (no affiliation, just a longtime happy user) is great for file sharing and even collaborative online document editing.

If you do not want to host your own instance, there are many great providers who will host one for you at a low cost.

See Configuration and syntax changes and Special packages. The latter this time includes changes around NextCloud 23 and Tor Browser prior to 12.5, both of which should be upgraded beforehand.
