VLC doesn't open through terminal or GUI

 If VLC is not opening either through the terminal or the graphical user interface (GUI), it can be due to various reasons. Here are some steps to troubleshoot and potentially resolve the issue:


1. **Check for Running Instances:**

   First, make sure there are no other instances of VLC running in the background. Use the following command to check:

   ```bash

   ps aux | grep vlc

   ```

   If you find any VLC processes running, you can kill them using `kill <PID>`, where `<PID>` is the process ID of VLC.


2. **Try Running VLC from the Terminal:**

   Open a terminal and try launching VLC with the following command to see if it provides any error messages:

   ```bash

   vlc

   ```

   If VLC fails to start, it may display error messages in the terminal that can help identify the problem.


3. **Check for Dependencies:**

   Ensure that VLC's dependencies are installed. Sometimes, missing libraries or packages can prevent VLC from running. You can check the installed dependencies using your package manager.


4. **Reinstall VLC:**

   If VLC is still not working, you might want to try reinstalling it. Use your package manager to remove VLC and then reinstall it. For example, on Debian-based systems, you can run:

   ```bash

   sudo apt-get purge vlc

   sudo apt-get install vlc

   ```


5. **Check for Disk Space:**

   Insufficient disk space on your system can sometimes prevent applications from running. Make sure you have enough free disk space.


6. **Check for Graphics Drivers:**

   If VLC relies on hardware acceleration for video playback, ensure that your graphics drivers are up to date.


7. **Check for Updates:**

   Ensure that your system and VLC are up to date with the latest updates. Sometimes, issues are resolved with software updates.


8. **Reset VLC Preferences:**

   If VLC was working previously and suddenly stopped, you can try resetting VLC preferences to default settings. Run the following command:

   ```bash

   vlc --reset-config

   ```


9. **Run VLC as a Different User:**

   Create a new user account on your system and try running VLC from that account. If it works, it might indicate that there is an issue with your user-specific configuration.


10. **Check for Hardware Issues:**

    Sometimes, VLC not opening could be related to hardware issues, such as failing hard drives or memory problems. Ensure your hardware is in good condition.


11. **Log Files:**

    Check system logs for any errors related to VLC. You can use the `dmesg` or system logs in `/var/log/` to see if there are any relevant error messages.


If none of the above steps resolves the issue, please provide any error messages or additional information you receive when trying to open VLC, as this information can be helpful for further troubleshooting.

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
