Comparing Signal-protocol-using messengers

There’re still privacy differences when you compare messenger apps all using the Signal protocol:

In this article, I’m going to compare WhatsApp, Signal, and Allo from a privacy perspective.

While all three apps use the same secure-messaging protocol, they differ on exactly what information is encrypted, what metadata is collected, and what, precisely, is stored in the cloud — and therefore available, in theory at least, to government snoops and wily hackers.

In the end, I’m going to advocate you use Signal whenever you can — which actually may not end up being as often as you would like.

AR create_with

I knew there was AR’s find_or_create_by  method but I didn’t know it had a very useful companion create_with .

This will either find a record  SomeModel.where(foo: "bar")  or create it with SomeModel.create(foo: "bar", some: "stuff") . Very useful.
