why unix sockets
//! This module provides implementations of `ActiveConnector` and `PassiveConnector` that are backed
//! by UNIX socket instead of the TCP sockets that are normally used.
//!
//! Using UNIX sockets instead of TCP ones serves multiple purpose:
//!
//! - creating and connecting to UNIX socket doesn't require specific permissions so using them in
//! tests mean that non-root users can run the tests. With TCP, listening on some ports may
//! require root privileges.
//! - We can easily create namespaces for the sockets used in each test by simply using the
//! filesystem hierarchy which means we avoid the classic "address already in use" pitfall. For

What are the biggest threats to your business/company?

Phishing

My biggest concern is phishing, ie being tricked into giving away sensitive information. As a foreigner, I am an easier target:

  • I don't speak German well enough to detect "weird" patterns in the documents I read that would normally make me suspicious.
