override hardcoded paths in executables

 Overriding hardcoded paths in executables can be a complex and potentially risky operation. It's generally not recommended, as it may compromise the integrity and security of the executable. However, there are a few approaches you can consider, keeping in mind that they might not be suitable for all situations and can have unintended consequences.


1. **Using Symbolic Links**:

   You can create symbolic links to replace hardcoded paths. For example, if an executable expects a library or resource at a specific path, you can create a symbolic link at that path pointing to the actual location of the library or resource. This approach might work for simple cases but can be cumbersome and might not work for all scenarios.


2. **LD_PRELOAD Environment Variable**:

   You can use the `LD_PRELOAD` environment variable to load a shared library that intercepts and overrides specific library or system calls made by the executable. This approach is often used for intercepting file-related calls and can be used to redirect file path requests. However, it's complex and can have unintended side effects.


3. **Patch the Binary**:

   You can attempt to modify the executable binary directly using a binary patching tool. This is a risky operation and may not be legal or ethical depending on the software's license agreement.


4. **Environment Variables**:

   Some executables may respect environment variables that influence their behavior. For instance, you can set the `PATH` environment variable to control where the executable searches for other programs. This can be useful in some cases.


5. **Wrappers or Custom Scripts**:

   Create a wrapper script that sets the necessary environment variables or modifies the command line arguments before running the executable. This allows you to customize the behavior without directly modifying the binary.


6. **Recompile the Executable**:

   If you have access to the source code of the executable, you can recompile it with the desired paths. This is the most reliable and maintainable way to change hardcoded paths.


7. **Containerization**:

   Consider using containerization technologies like Docker or container runtimes (e.g., Podman) that allow you to package an application and its dependencies together. This can help isolate the application from the host environment and avoid hardcoded path issues.


Before attempting any of these methods, make sure you fully understand the implications and potential risks. Modifying executables can lead to instability or security vulnerabilities. Always have a backup or a rollback plan in case something goes wrong. Additionally, ensure that your actions comply with any relevant software licenses or legal agreements.

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
