Hiding the progress bar in the adapter from the activity section

 To hide the progress bar in an adapter from the activity section, you typically need to communicate with the adapter and update the visibility of the progress bar within the adapter's view. Here's a general outline of how you can achieve this:


1. **Define a Method in the Adapter**:

   In your adapter, define a method that allows you to change the visibility of the progress bar. This method should be accessible from the activity.


   ```java

   public class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {

       private boolean progressBarVisible = true;


       public void setProgressBarVisible(boolean visible) {

           progressBarVisible = visible;

           notifyDataSetChanged(); // Notify the adapter to refresh the view

       }


       // ... other adapter methods

   }

   ```


2. **Activity Interaction**:

   In your activity, get a reference to the adapter and call the method to change the visibility of the progress bar.


   ```java

   MyAdapter adapter = new MyAdapter(data); // Initialize your adapter

   recyclerView.setAdapter(adapter);


   // To hide the progress bar

   adapter.setProgressBarVisible(false);


   // To show the progress bar

   adapter.setProgressBarVisible(true);

   ```


3. **Update Adapter's `onBindViewHolder`**:

   In your adapter, modify the `onBindViewHolder` method to set the visibility of the progress bar based on the value of `progressBarVisible`.


   ```java

   @Override

   public void onBindViewHolder(MyViewHolder holder, int position) {

       if (progressBarVisible) {

           holder.progressBar.setVisibility(View.VISIBLE);

           holder.contentLayout.setVisibility(View.GONE);

       } else {

           holder.progressBar.setVisibility(View.GONE);

           holder.contentLayout.setVisibility(View.VISIBLE);

           // Bind your data to the views

       }

   }

   ```


With this approach, you can control the visibility of the progress bar within the adapter from your activity. When you call `setProgressBarVisible` from your activity, it triggers a refresh of the adapter's views to hide or show the progress bar as needed.


Remember to customize the code to fit your specific adapter and layout structure.

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
