  "description": "Anyone who works with programming languages will sooner or later come across Alan Turing. Sed is generally better known as a command line command that can be used in a shell on a Unix or Linux computer system. What is less well known is that sed, the so-called stream editor, is a programming language. And even less well known is that sed has been proven to be Turing complete and thus represents shortly spoken a fully capable and complete programming system. This article addresses this topic and is well worth reading.",
