XML-RPC: Was so aussieht, als wäre jemand mit dem Kopf auf der Tastatur eingeschlafen, ist in Wirklichkeit eine Schwachstelle in WordPress, über die Hacker dich mit einer DDoS- oder Brute-Force-Attacke angreifen können.

Varlink is an interface description format and protocol that aims to make services accessible to both humans and machines in the simplest feasible way.

A varlink interface combines the classic UNIX command line options, STDIN/OUT/ERROR text formats, man pages, service metadata and provides the equivalent over a single file descriptor, a.k.a. “FD3”.

Varlink is plain-text, type-safe, discoverable, self-documenting, remotable, testable, easy to debug. Varlink is accessible from any programming environment. See the Ideals page for more. And everybody likes Screenshots.
