stash clear/drop


Remove all the stash entries. Note that those entries will then be subject to pruning, and may be impossible to recover (see Examples below for a possible strategy).

drop [-q|--quiet] [<stash>]

Remove a single stash entry from the list of stash entries. When no <stash> is given, it removes the latest one. i.e. stash@{0}, otherwise <stash> must be a valid stash log reference of the form stash@{<revision>}.

Docker can build images automatically by reading the instructions from a Dockerfile.

Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image.

Using docker build users can create an automated build that executes several command-line instructions in succession.

Emmet is a set of plug-ins for text editors that allow for high-speed coding and editing in HTML, XML, XSL, and other structured code formats via content assist.

Formerly known as Zen Coding.

Emmet is primarily independent from any text editor, as the engine works directly with text rather than with any particular software.

Kubernetes Architecture Overview

Shared by joubin on Mon Feb 19 2018


cgroups is a Linux kernel feature that limits, accounts for, and isolates the resource usage (CPU, memory, disk I/O, network, etc.) of a collection of processes.

Engineers at Google (primarily Paul Menage and Rohit Seth) started the work on this feature in 2006 under the name "process containers".

In late 2007, the nomenclature changed to "control groups" to avoid confusion caused by multiple meanings of the term "container" in the Linux kernel context, and the control groups functionality was merged into the Linux kernel mainline in kernel version 2.6.24, which was released in January 2008. Since then, developers have added many new features and controllers, such as support for kernfs in 2014, firewalling, and unified hierarchy.

EAV Model

The Entity-Attribute-Value model or EAV is also sometimes referred to at the Object-Attribute-Value Model, or even the Open Schema.

This is a data model that is often used in instances where the amount of attributes, properties, or parameters that can be used to define an entity are potentially limitless.

Attributes are defined disconnected from entities. The values table link back to the attribute and the entity itself.

Browser Service Worker

A service worker is a script that your browser runs in the background, separate from a web page.

They don't need a web page or user interaction.

Examples of background tasks are:

  • Push Notifications
  • Background Sync

The reason this is such an exciting API is that it allows you to support offline experiences.

Manifest file

A manifest file, in computing, is a file containing metadata for a group of accompanying files that are part of a set or coherent unit.

For example, an executable binary file of a computer program may have a manifest describing the name, version number, license and the constituting files of the program.

The term is borrowed from a cargo shipping procedure, where a ship manifest would list the crew and/or cargo of a vessel.

Docker swarm mode

Swarm mode refers to cluster management and orchestration features embedded in Docker Engine. When you initialize a new swarm (cluster) or join nodes to a swarm, the Docker Engine runs in swarm mode.

Kubernetes vs Docker Swarm

Kubernetes is a full-fledged container orchestration system that includes a scheduler, health checks, rolling upgrades, autoscaling, etc. whereas Docker Swarm is mainly about providing a cluster-wide view of a single Docker engine.
