Fix: Make Neotree open directory in full screen

 NeoTree is a directory tree plugin for Emacs that provides a sidebar file explorer. By default, it doesn't open directories in full screen. However, you can make NeoTree open directories in full screen by customizing its behavior. Here's a general approach:


1. **Install NeoTree**: If you haven't already, you need to install NeoTree. You can install it using a package manager like `use-package` if you're using Emacs.


2. **Customize NeoTree Behavior**: Add the following lines to your Emacs configuration file (typically `init.el` or `~/.emacs.d/init.el`) to customize NeoTree's behavior:


   ```emacs-lisp

   ;; Define a function to open NeoTree in full screen

   (defun neotree-toggle-fullscreen ()

     (interactive)

     (neotree-toggle)

     (if (neo-global--window-exists-p)

         (neotree-show)

       (neotree-hide)))


   ;; Keybinding to toggle full screen NeoTree

   (global-set-key [f8] 'neotree-toggle-fullscreen)

   ```


   In the code above, we define a function `neotree-toggle-fullscreen` that toggles NeoTree in and out of full screen when called. We then bind this function to a key (F8 in this example), so you can use that key to toggle full-screen NeoTree.


3. **Reload Configuration**: After adding these lines to your Emacs configuration file, save the file and then reload your Emacs configuration, or restart Emacs.


4. **Open NeoTree in Full Screen**: To open NeoTree in full screen for a directory, navigate to the directory in your main buffer, and then press the key you assigned (F8 in the example) to toggle full-screen NeoTree.


This customization allows you to open NeoTree in full screen using a keyboard shortcut. You can modify the keybinding to your preference by changing `[f8]` to a different key sequence.

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
