Ducktape rust to c compiler via assembly

There isn't a project called "Ducktape" that specifically serves as a Rust to C compiler via assembly. However, Rust has the ability to interoperate with C code and can call C functions directly. Here's how you can achieve interoperability between Rust and C, including the use of assembly:


1. **Rust to C Interoperability**:

   - Rust has built-in support for calling C functions using the `extern` keyword. You can declare C functions in your Rust code and then call them as if they were regular Rust functions. This means you don't need a separate compiler to convert Rust to C.


   ```rust

   extern "C" {

       fn c_function(arg: i32) -> i32;

   }

   ```


   You can call `c_function` as you would any other Rust function.


2. **Assembly Code Integration**:

   - If you want to include assembly code in your project, you can use inline assembly within Rust code. Rust supports inline assembly using the `asm!` macro. You can include assembly snippets directly in your Rust code.


   ```rust

   fn main() {

       let result: i32;

       unsafe {

           asm!(

               "mov $0, 42",

               out(reg) result,

           );

       }

       println!("Result: {}", result);

   }

   ```


   This example uses inline assembly to assign the value 42 to the `result` variable.


3. **Rust FFI (Foreign Function Interface)**:

   - To integrate C code and assembly more seamlessly with Rust, you can use Rust's FFI capabilities. This allows you to define C functions in Rust and then implement them in C or assembly. You can also link external C libraries directly from Rust.


   Here's an example of a simple FFI implementation in Rust:


   ```rust

   extern "C" {

       fn my_c_function(arg: i32) -> i32;

   }

   ```


   You can provide the implementation for `my_c_function` in C or assembly and link it with your Rust project.


Please note that the specific tools, libraries, and techniques may have evolved since my last knowledge update. Be sure to check the latest Rust and assembly documentation and resources for the most up-to-date information on Rust and C integration, as well as Rust's support for inline assembly.

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
