In defence of swap: common misconceptions (chrisdown.name)
 

To be clear, I don't blame the poster of this comment at all for the content of their post – this is accepted as "common knowledge" by a lot of Linux sysadmins and is probably one of the most likely things that you will hear from one if you ask them to talk about swap. It is unfortunately also, however, a misunderstanding of the purpose and use of swap, especially on modern systems.

Universally Unique IDentifiers (UUID) (www.ietf.org)
 

This specification defines the UUIDs (Universally Unique IDentifiers) and the UUID Uniform Resource Name (URN) namespace. UUIDs are also known as GUIDs (Globally Unique IDentifiers). A UUID is 128 bits long and is intended to guarantee uniqueness across space and time. UUIDs were originally used in the Apollo Network Computing System and later in the Open Software Foundation's (OSF) Distributed Computing Environment (DCE), and then in Microsoft Windows platforms.

Before nginx was a thing, I worked with a guy who forked apache httpd and wrote this blog in C, like, literally embedded html and css inside the server, so when he made a tpyo or was adding another post he had to recompile the source code. The performance was out of this world.
