Fix: Prevent overscroll/overflow in Skeleton UI Modal component

 To prevent overscroll or overflow in a Skeleton UI modal component, you can use CSS to control the scrolling behavior of the modal. Here are a few strategies you can employ:


1. **Hidden Overflow:**

   One common approach is to set `overflow: hidden` on the modal's content container. This prevents the content from scrolling. This approach is suitable for a simple modal with static content.


   ```css

   .modal-content {

       overflow: hidden;

   }

   ```


2. **Fixed Position:**

   You can use `position: fixed` to make the modal stick to the viewport and avoid scrolling. This approach is useful for small modals or overlays.


   ```css

   .modal {

       position: fixed;

       top: 50%;

       left: 50%;

       transform: translate(-50%, -50%);

   }

   ```


3. **Fixed Body:**

   In some cases, you may want to prevent the entire page from scrolling when the modal is open. To achieve this, apply `position: fixed` to the `body` element when the modal is open and restore the original positioning when the modal is closed. You can use JavaScript to toggle this behavior.


   ```css

   body.modal-open {

       position: fixed;

       overflow: hidden;

   }

   ```


   JavaScript to toggle the class:


   ```javascript

   const openModalButton = document.getElementById('open-modal-button');

   const closeModalButton = document.getElementById('close-modal-button');


   openModalButton.addEventListener('click', () => {

       document.body.classList.add('modal-open');

   });


   closeModalButton.addEventListener('click', () => {

       document.body.classList.remove('modal-open');

   });

   ```


4. **Scrollable Modal Content:**

   In some cases, you may have a modal with a large amount of content that you want to make scrollable within the modal. In this case, apply `overflow: auto` to the modal content and set a `max-height` to limit the height and enable scrolling when the content exceeds that limit.


   ```css

   .modal-content {

       overflow: auto;

       max-height: 80vh; /* Adjust the height as needed */

   }

   ```


The approach you choose depends on the specific behavior and design of your modal component. You can combine these techniques as needed to achieve the desired user experience. Additionally, you might want to apply these styles dynamically in response to modal opening and closing events.

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
