• strict triangular form

  A system is said to be in strict triangular form if, in the kth equation, the coefficients of the first k-1 variables are all zero and the coefficient of $x_{k}$ is nonzero.

• Elementary Row Operations
• I. Interchange two rows.

Use antd to develop form

Keep UI layer clean

In React, the UI layer means the render function of the page component. Because of the flexibility of React, redundant logic are usually put into the render method, which will easily lead to tremendous render methods. When using antd.Form component, initial values of form fields, form validation, transformation of form values to the UI components' props are all defined in page component. But this may not be a good practice. A clean render method of page component should only concern about the representation logic, for example, the layout of components and user interactions.

To achieve this goal, where to place the initialization, validation of form, and the transformation of form values to components' props need to be taken into account. First, antd form's getFieldDecorator method declare s the behaviour of one field with an configuration object. The object contains initial value of the field, the validating rules, and some tranformation function

In grafana, when we click in the chart and drag, we can select the time range to display. The effect will be propagated to the whole dashboard, and every panel will be set to the specific time range.

Now we try to realize the same effect using React and Highcharts.

1. The highchart's option to enable the function that we can drag to select time range is below.

{
  chart: { zoomType: 'x' }
}

// ...

export class ComponentCtrl {
  // ...
  onClick() {
    // We can access outer scope function here with the binding name.
    this.outerHandleClick({param1: 1, param2: 2}) // We can also pass parameters to outer function.
  }
}

Directives

https://docs.angularjs.org/guide/directive

Definition

At a high level, directives are markers on a DOM element (such as an attribute, element name, comment or CSS class) that tell AngularJS's HTML compiler ($compile) to attach a specified behavior to that DOM element (e.g. via event listeners), or even to transform the DOM element and its children.

differences between iterables and iterators

iterables have an __iter__ method that instantiates a new iterator every time. iterators implement a __next__ method that returns individual items, and an __iter__ method that returns self.

Therefore, iterators are also iterable, but iterables are not iterators.
