node_modules not installed when installing Next JS

 If you encounter an issue with `node_modules` not being installed when setting up a Next.js project, it's likely related to a problem during the project initialization process or the package installation process. Here are steps to troubleshoot and resolve this issue:


1. **Initialize a New Project**:

   Make sure you are creating a new Next.js project using the following commands:

   

   ```bash

   npx create-next-app your-app-name

   ```


   Replace `your-app-name` with the desired name for your project.


2. **Navigate to the Project Directory**:

   After the project is created, change your working directory to the newly created project folder:


   ```bash

   cd your-app-name

   ```


3. **Install Dependencies**:

   Next, run the following command to install the project dependencies, including `node_modules`:


   ```bash

   npm install

   # OR

   yarn install

   ```


   Ensure you have Node.js and npm (Node Package Manager) or Yarn installed globally on your system. You can download them from their respective websites if you haven't already.


4. **Check for Errors**:

   While running the `npm install` or `yarn install` command, pay attention to the console for any error messages. If you encounter errors during the installation process, address them as needed. Common issues include network problems or permission issues.


5. **Recreate the Project**:

   If the issue persists, you may consider recreating the project from scratch. Sometimes, the initial project setup can encounter issues that are best resolved by starting fresh.


6. **Update npm or Yarn**:

   Ensure you have the latest versions of npm or Yarn by running the following commands:


   To update npm:

   ```bash

   npm install -g npm

   ```


   To update Yarn:

   ```bash

   npm install -g yarn

   ```


7. **Check for .gitignore or .npmignore**:

   Make sure that there are no exclusions for `node_modules` in your project's `.gitignore` or `.npmignore` files. Such exclusions can prevent the installation of `node_modules` during project setup.


8. **Clean Cache**:

   Sometimes, issues can be related to cache problems. You can clear the cache for npm or Yarn with the following commands:


   For npm:

   ```bash

   npm cache clean --force

   ```


   For Yarn:

   ```bash

   yarn cache clean

   ```


After following these steps, you should be able to initialize and set up your Next.js project with the necessary `node_modules` installed. If you continue to encounter issues, please provide more specific details about any error messages or issues you're facing for further assistance.

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
