Distribute percentage across different inputs

To distribute a percentage across different inputs in a React.js application, you can follow these steps:

1. **Create a React Component**: Create a React component that will display the inputs and allow users to specify percentages.

2. **Set Up State**: Use React state to manage the input values and percentage distribution. You can use the `useState` hook for functional components or the `this.state` for class components.

3. **Render Inputs**: Render input fields that allow users to specify the percentage for each item. You can use text inputs, sliders, or any other input method you prefer.

4. **Handle Input Changes**: Create event handlers to capture changes in the input values. When a user modifies the percentage for one item, the event handler should update the state accordingly.

5. **Distribute Percentages**: Calculate and display the allocated percentage for each item based on the user's input. You'll need to ensure that the total percentage doesn't exceed 100% or any other limit you set.

6. **Display Results**: Show the calculated distribution for each item to the user.

Here's a simplified example of how this could look in a functional component:

```javascript
import React, { useState } from 'react';

function PercentageDistribution() {
  const [percentages, setPercentages] = useState({ item1: 0, item2: 0, item3: 0 });

  const handlePercentageChange = (item, value) => {
    // Update the percentage for the specified item
    setPercentages({ ...percentages, [item]: value });
  };

  const totalPercentage = Object.values(percentages).reduce((total, percentage) => total + parseInt(percentage), 0);

  return (
    <div>
      <div>
        <label>Item 1:</label>
        <input type="number" value={percentages.item1} onChange={(e) => handlePercentageChange('item1', e.target.value)} />
      </div>
      <div>
        <label>Item 2:</label>
        <input type="number" value={percentages.item2} onChange={(e) => handlePercentageChange('item2', e.target.value)} />
      </div>
      <div>
        <label>Item 3:</label>
        <input type="number" value={percentages.item3} onChange={(e) => handlePercentageChange('item3', e.target.value)} />
      </div>
      <div>Total Percentage: {totalPercentage}%</div>
      <div>Distribution: {percentages.item1}% {percentages.item2}% {percentages.item3}%</div>
    </div>
  );
}

export default PercentageDistribution;
```

This is a basic example, and you can customize it to meet your specific requirements. You may also want to add validation to ensure that the total percentage remains within the desired range.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
