Fix: Commandline build for android on Alpine is failing

 Building Android applications on Alpine Linux can be a bit challenging due to differences in library and toolchain support compared to more common Linux distributions. Here are some steps to address common issues when building Android apps on Alpine:


1. **Install Dependencies**: Ensure that you have the necessary dependencies installed. You'll need a JDK, Android SDK, NDK, and build tools. Run the following to install OpenJDK, which is commonly used for Android development:


   ```

   apk add openjdk11

   ```


   You can install other dependencies similarly.


2. **Update Environment Variables**: Set environment variables like `JAVA_HOME`, `ANDROID_HOME`, `PATH`, and other variables as needed to point to the locations of your Java, Android SDK, and NDK installations.


3. **Use a Compatible NDK**: Make sure you are using an NDK version that is compatible with your Android project. Some NDK versions may not work properly on Alpine.


4. **C/C++ Build Issues**: If your Android project contains native code (C/C++), ensure that you have the necessary libraries and build tools for compiling native code. You might need to install `cmake`, `make`, and other build tools.


5. **32-bit Libraries**: If you are targeting 32-bit Android platforms, you might need to install 32-bit libraries on your 64-bit Alpine system. Use the `apk add` command to install these libraries.


6. **NDK Revision**: Double-check the `ndkVersion` in your `build.gradle` or `local.properties` to ensure it matches the version of NDK you have installed.


7. **Check Build Scripts**: Review your project's `build.gradle` and build scripts to ensure they don't contain any hard-coded paths or dependencies that are specific to other Linux distributions.


8. **Docker**: Consider using a Docker container with a Linux distribution that is better supported for Android development, such as Ubuntu or Debian. This can help isolate your build environment from your host system.


9. **Community Support**: If you encounter specific issues, search for solutions and known problems related to building Android on Alpine Linux in developer forums and communities. Other developers might have encountered similar problems and found workarounds.


Please note that building Android applications on Alpine can be more challenging due to its minimalistic nature and differences in library and toolchain support. While it's possible to make it work, using a more common Linux distribution like Ubuntu or Debian might be a more straightforward solution for Android development.

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
