Accidently removes an important document If you are a Unix person trying to operate Windows, you probably gonna typed RM -RF SOME-FOLDER in Powershell and expect it to remove a folder. But unfortunately, it won’t work on windows, even In the older versions of the windows terminal system. To delete a directory you’ll have to use rmdir /s /q the-folder-name.  But again it won't work anymore on Windows PowerShell. You have to learn lots of power shell commands.  Solutions To remove some folders on your computer using windows PowerShell, execute this command line below: remove-item -recurse -force THE_FOLDER_NAME The recurse is equivalent to “-r” in Linux. It forces the commands to remove the nested folder. And the -force is similar to ‘-f’ in Linux. To force delete the file if some other program is holding it. Those commands also can be applied to remove files. But without -recurse and -force options. That command is similar to the Unix rm -rf folder.  And in the older Windo...

MySQL and MariaDB password As already mentioned in the title of this blog, this error message sometimes occurred when we are trying to update our root password database, either MySQL or MariaDB, The error says: ERROR 1348 (HY000): Column 'Password' is not updatable This is because if we use this SQL command to update our database root password, and it turn out to be Restricted by MySQL to use update on mysql database.

Spring Boot is a handy tool that simplifies the development of Spring Framework applications by reducing the need for cumbersome configuration. In this tutorial, I'll guide you through creating a Spring Boot application using the Netbeans IDE. While you can certainly create a Spring Boot application in Netbeans manually, it's much easier with a plugin designed for Spring development. Here's a step-by-step guide to get you started: 1. Install the Spring Boot Plugin: Open Netbeans and navigate to the Tools menu. Click on "Plugins." Once the Plugins window opens, select the "Available Plugins" tab. Look for the "Nb SpringBoot" plugin, then install and activate it. 2. Create a New Spring Boot Project: After restarting Netbeans IDE, you can create a new project with Spring Boot. Go to File > New Project. Under Categories, select Maven, then choose "Spring Boot Basic." 3. Add Dependencies: With your new project created, open the po...

Microservice Spring with Apache Kafka Today, I want to share how to use Kafka. It's quite interesting once you get the hang of it, and I hope my explanation will make it a bit easier for you. So, Kafka is primarily known as an asynchronous messaging queuing system. This means it allows different parts of your application to communicate with each other without waiting for immediate responses. However, there are times when you might need a more immediate reply from another service in your project. Luckily, Kafka can handle this too. Here’s how it works: The client side sends a message to the server side via Kafka. This message includes a special identifier in the Kafka header request, known as KafkaHeaders.CORRELATION_ID, along with a topic where the server should respond. The server, after processing the request, sends a message back to the same topic with the same correlation ID. This way, the client knows that the message is a response to its initial request and can act accordingl...
