I haven’t used Atuin (though I think I might give it a try), but maybe you could use the atuin history list command and pipe that into something like fzf or ripgrep to get case insensitive search?

I’ve noticed for my North American friends it’s easy to convince them to move to Signal (from SMS or Messenger), but my European friends are all pretty entrenched in WhatsApp. On one hand WhatsApp is certainly more secure, but on the other we can’t really trust a closed source implementation (and they’ll still collect metadata which makes me uncomfortable).

I’m just glad I don’t have to use SMS anymore honestly

I understand and value the idea of self-hosting or federation to decentralize services, but Signal is currently my most used chat app for the sole reason that I can tell a friend to go download it and it just works. Supporting self-hosted servers or federation doesn’t necessarily mean that the UX has to be bad, but for small organizations I think the radical focus on a specific experience is the best way to make a good product, and if this is the sacrifice that was made so that we could have a simple, reliable, private messenger then I’m happy with that tradeoff.

As an example, chat protocols/implementations like Matrix have a lot of potential, but the foundational decisions around decentralization mean that it takes way more work to make it seamless to use. You can’t download a client and start chatting immediately, you need to think about what server to connect to, and that’s already enough of a barrier to make it a no-go for a lot of the folks I regularly chat with who just don’t care enough about privacy/FOSS to put in the effort.

No specific indication, but as the organization matures and brings on new folks it’s always a little uneasy to see the old guard leave. Only time will tell!

To be honest, while crypto is probably the closest we have to an actually private payment option (Monero etc), I’m generally not a fan of it for this usage because unlike the rest of the app, it has a much steeper learning curve AND is a common target for scams, which makes it much less approachable for the average user. I love Signal because my mom can use it and I can trust that she’s protected, but I would not recommend she tries using the payment option within it regardless of what coin they use because the rigamaroll of going to some exchange to buy it is already a dicey proposition.

I’m cautiously optimistic that this isn’t a warning sign. I can imagine wanting to do something new after spending so long working on one project, but if he left because things were straying from his vision of Signal that could be a bad sign.
