Async/await magic

As far as I got from the internet, the async/await stuff is a sort of paradigm enrichment of the python ecosystem. One can now access a for of concurrent execution thanks to an event loop. Much like in the browser. I'm ok with that, but I don't really get how to bridge what one knows from the classic synchronous execution workflow, so I experimented a bit. The async_iter_over_tcp.py is just a playground that can be invoked like this (ITER_TIMES defaults to 5):

From Aegis to pass

[Aegis][0] is a nice android app to manage OTP tokens. [pass][1] is the password manager for *nix systems. I know that the whole point of the two factor authentication philosophy is to physically separate the bearers of authentication information, but the lifetime of my physical devices is quite random, so WHATEVER: I concoted this procedure to copy the OTP passwords from aegis to pass.
