Full system crash when playing full screen video

 A full system crash when playing a full-screen video can be caused by a variety of factors. Here are some steps to diagnose and potentially resolve the issue:


1. **Check Hardware Temperature:** Overheating is a common cause of system crashes. Ensure that your CPU and GPU are not overheating while playing video. Clean any dust from cooling fans and consider using monitoring tools to check temperatures.


2. **Update Graphics Drivers:** Outdated or incompatible graphics drivers can lead to system crashes. Update your GPU drivers to the latest version from the official website of the manufacturer (e.g., NVIDIA, AMD).


3. **Check for System Updates:** Ensure that your operating system is up to date with the latest security and stability updates.


4. **Adjust Video Playback Software:** Try using different video playback software to see if the issue is specific to one application. VLC, MPV, or similar programs can be alternatives.


5. **Hardware Acceleration:** Experiment with hardware acceleration settings in your video player. Some systems may have issues with hardware acceleration, and disabling it might help.


6. **Check for Software Conflicts:** Other software or drivers running in the background can interfere with video playback. Disable unnecessary applications and services while playing video.


7. **Update or Disable Browser Plugins:** If the video is being played in a web browser, check for outdated or problematic browser plugins, especially Flash. Consider disabling or updating them.


8. **Check for Malware:** Malware can cause system instability. Run a malware scan to ensure your system is clean.


9. **Memory Issues:** Faulty RAM can lead to system crashes. Run a memory test using tools like MemTest86 to check for memory errors.


10. **Power Supply and Hardware Stability:** Ensure your power supply is stable and provides enough power for your system. Hardware issues, such as a failing power supply, can lead to crashes.


11. **Check System Logs:** Review system logs, including `/var/log/syslog` on Linux or the Event Viewer on Windows, for error messages or events around the time of the crash. They might provide clues to the cause.


12. **BIOS/UEFI Updates:** Check if there are updates for your system's BIOS or UEFI firmware. Sometimes, firmware updates can improve hardware compatibility and stability.


13. **Testing on Another System:** Try playing the same video on a different computer to see if the issue persists. This can help determine if it's a software or hardware problem.


14. **Contact Support:** If the issue remains unresolved, consider reaching out to the technical support of the hardware manufacturer or seeking assistance from a professional technician.


It's essential to isolate and identify the cause of the crashes through a process of elimination. Pay attention to any error messages, system behavior, and other factors that might help pinpoint 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
