Fix: Spring automatically uses fastTime instead of Date?

 In Spring Framework, when dealing with dates and times, it doesn't automatically use the `fastTime` field of `java.util.Date`. Instead, Spring often prefers to use the newer date and time classes provided by the `java.time` package introduced in Java 8, such as `LocalDate`, `LocalTime`, `LocalDateTime`, `ZonedDateTime`, and more.


The `java.util.Date` class is considered legacy and has some limitations and issues, such as not being time zone-aware. The `java.time` classes provide better support for modern date and time operations.


Spring Framework encourages the use of `java.time` classes in many of its modules, including:


1. **Spring Data**: Spring Data JPA and other data access modules often support `java.time` classes for mapping date and time values in databases.


2. **Spring Boot**: Spring Boot, a project within the Spring ecosystem, includes automatic configuration and support for `java.time` classes, which makes it easy to work with modern date and time types.


3. **Spring MVC**: Spring's web framework, Spring MVC, supports `java.time` types for request and response binding, making it straightforward to work with date and time data in web applications.


4. **Spring Security**: Spring Security can handle user authentication and access control with `java.time` types.


While Spring does support `java.time` classes, it doesn't prevent you from using `java.util.Date` if you have legacy code that uses it. However, it's recommended to migrate to `java.time` whenever possible for more robust and modern date and time handling.


When configuring Spring beans or using Spring's data access and conversion features, you can use the `@DateTimeFormat` annotation to specify date and time format patterns, which is especially useful when working with date-related fields in form binding or DTOs.


Here's an example of using `@DateTimeFormat` with a `LocalDate` field in a Spring bean:


```java

import org.springframework.format.annotation.DateTimeFormat;


public class MyBean {

    @DateTimeFormat(pattern = "yyyy-MM-dd")

    private LocalDate localDate;

    

    // Getter and Setter

}

```


This allows you to specify the format for parsing and formatting date values when working with `LocalDate` in your Spring application.

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
