Firewall system in computer help you secure your computer manage incoming and outgoing connection, typically identified using port, either you want to allow some specific port or block it. It useful for preventing unauthorized people using our computer resources, stealing our sensitive data and any kind of hacking activities.

Windows 10 by default have firewall, so it is safe for you, you don't need to worry about hacker or bad people doing bad things to your computer while you are using public internet. Mac and Ubuntu or any other Linux don't enabled the firewall system by default, if you want to enable them, we will covered it later in this blog.

It is not necessary for you to have a firewall activated if your computer is not visible by public, either by public internet, like if you are using WiFi cafe, etc. Even though you are using public internet and no firewall, it is not that always something bad will happens to your computer. Our computer is getting smart and less bug day by day.

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.

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...
