    Gobot is set of libraries in the Go programming language for robotics and physical computing. It provides a simple, yet powerful way to create solutions that incorporate multiple, different hardware devices at the same time. Want to use Ruby on robots? Check out our sister project Artoo (http://artoo.io). Want to use Node.js? Check out our sister project Cylon (http://cylonjs.com).

  • In robotics and automation, a control loop is a non-terminating loop that regulates the state of a system.
  • controllers are control loops that watch the state of your cluster, then make or request changes where needed
  • Each controller tries to move the current cluster state closer to the desired state.
  • ...12 more annotations...
  • A controller tracks at least one Kubernetes resource type.
  • The controller(s) for that resource are responsible for making the current state come closer to that desired state.
  • in Kubernetes, a controller will send messages to the API server that have useful side effects.
  • Built-in controllers manage state by interacting with the cluster API server.
  • By contrast with Job, some controllers need to make changes to things outside of your cluster.
  • the controller makes some change to bring about your desired state, and then reports current state back to your cluster's API server. Other control loops can observe that reported data and take their own actions.
  • As long as the controllers for your cluster are running and able to make useful changes, it doesn't matter if the overall state is stable or not.
  • Kubernetes uses lots of controllers that each manage a particular aspect of cluster state.
  • a particular control loop (controller) uses one kind of resource as its desired state, and has a different kind of resource that it manages to make that desired state happen.
  • There can be several controllers that create or update the same kind of object.
  • you can have Deployments and Jobs; these both create Pods. The Job controller does not delete the Pods that your Deployment created, because there is information (labels) the controllers can use to tell those Pods apart.
  • Kubernetes comes with a set of built-in controllers that run inside the kube-controller-manager.

  • “I should really figure out what that does someday.”
  • today is that day
  • jquery-ujs wires event handlers to eligible DOM elements to provide enhanced functionality.
  • ...11 more annotations...
  • In most cases, the eligible DOM elements are identified by HTML5 data attributes.
  • using JavaScript to progressively enhance the user experience for capable browsers without negatively impacting clients that do not support or do not enable JavaScript.

      讓 user 有更好體驗，但是也不影響到那些沒有 JS 支援的 user
  • jquery-ujs attaches a handler to links with the data-method attribute
  • When the link is clicked, the handler constructs an HTML form along with a hidden input that sets the _method parameter to the requested HTTP verb
  • jquery-ujs attaches a handler to links or forms with the data-confirm attribute that displays a JavaScript confirmation dialog
  • Users double click links and buttons all the time.
  • Links and buttons that have a data-disable-with attribute get a click handler that disables the element and updates the text of the button to that which was provided in the data attribute and disables the button.

      優雅地處理了使用者重複點擊傳送按鈕的問題。
  • If the action is performed via AJAX, the handler will re-enable the button and reset the text when the request completes.
  • Thanks to jquery-ujs and Rails’ respond_with, setting remote: true is likely the quickest way to get your Rails application making AJAX requests.
  • support both AJAX and standard requests at the same time.
  • Cross-Site Request Forgery (CSRF) is an attack wherein the attacker tricks the user into submitting a request to an application the user is likely already authenticated to.
