QWebEngineView in PySide6 not loading any page

 If you're using `QWebEngineView` in PySide6, and it's not loading any web pages, there are several things you can check to diagnose and potentially resolve the issue. Here are some troubleshooting steps:


1. **Check Dependencies**: Make sure you have Qt's WebEngine module installed and properly configured. You may need to install PyQtWebEngine, which provides the necessary Qt WebEngine support for PySide6. Verify that you've included the correct import statements.


2. **Import Statements**: Ensure that you have the proper import statements in your code, such as:


   ```python

   from PySide6.QtWebEngineWidgets import QWebEngineView

   ```


   Note that PySide6 moved its WebEngine module to `QtWebEngineWidgets`, so make sure you are using the correct import path.


3. **Initialize Qt Application**: Before using `QWebEngineView`, ensure that you have initialized a Qt application using `QApplication`. The Qt application event loop is required for `QWebEngineView` to function properly.


   ```python

   from PySide6.QtWidgets import QApplication, QMainWindow

   app = QApplication([])

   ```


4. **Create a Web Engine View**: Create an instance of `QWebEngineView` and add it to your application or a widget.


   ```python

   view = QWebEngineView()

   view.setUrl(QUrl("https://example.com"))

   ```


5. **Layout and Display**: Make sure you add the `QWebEngineView` to a layout or widget that is part of your application's user interface. Ensure that the widget containing the view is visible and has sufficient dimensions.


6. **Signals and Slots**: You can connect signals to slots to handle events related to loading web pages. For example:


   ```python

   view.loadFinished.connect(your_callback_function)

   ```


7. **Handle Errors**: Implement error handling for situations where the web page cannot be loaded. For example:


   ```python

   def handleLoadFinished(ok):

       if not ok:

           print("Page loading failed")


   view.loadFinished.connect(handleLoadFinished)

   ```


8. **Error Output**: Check the console output for any error messages or warnings that may provide insights into the problem. Logging can be helpful for debugging.


9. **Permissions**: Ensure that your application has necessary network and internet permissions to access the web.


10. **Firewall and Proxy Settings**: Sometimes, firewall or proxy settings can interfere with web page loading. Check your system's network configuration.


11. **SSL Issues**: If you're trying to load HTTPS websites, ensure that your system has the necessary SSL certificates. PySide6 relies on the system's SSL libraries.


12. **Update PySide6**: Ensure that you are using an up-to-date version of PySide6, as updates may include bug fixes.


13. **Run Event Loop**: Finally, make sure to run the Qt event loop by calling `app.exec_()` at the end of your application to start the GUI event loop.


If you've checked all these points and are still facing issues, it's a good idea to consult the official documentation for PySide6 and Qt's WebEngine module and look for specific examples that match your use case. Additionally, inspect any error messages or logs for more detailed information about the problem.

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
