Kubernetes

Kubernetes (commonly stylized as k8s) is an open-source container orchestration system for automating application deployment, scaling, and management.It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation. It aims to provide a “platform for automating deployment, scaling, and operations of application containers across clusters of hosts”. It works with a range of container tools, including Docker. Many cloud services offer a Kubernetes-based platform or infrastructure as a service (PaaS or IaaS) on which Kubernetes can be deployed as a platform-providing service. Many vendors also provide their own branded Kubernetes distributions.

Tempo rubato

Jovan Stosic February 14, 2019

Tempo rubato ([ˈtɛmpo ruˈbaːto]; “free in the presentation”, Italian for “stolen time”) is a musical term referring to expressive and rhythmic freedom by a slight speeding up and then slowing down of the tempo of a piece at the discretion of the soloist or the conductor. Rubato is an expressive shaping of music that is a part of phrasing.[1]

While rubato is often loosely taken to mean playing with expressive and rhythmic freedom, it was traditionally used specifically in the context of expression by speeding up and then slowing down the tempo. In the past, expressive and free playing (beyond only rubato) was often associated with the terms “ad libitum.” Rubato, even when not notated, is often used liberally by musicians; e.g. singers frequently use it intuitively to let the tempo of the melody expressively shift slightly and freely above that of the accompaniment. This intuitive shifting leads to rubato’s main effect: to make music sound expressive and natural. Frédéric Chopin is often mentioned in context with rubato (see Chopin’s technique and performance style).
