FZF combine with VIM

I've recently discovered a neat trick that combines FZF and Silver Searcher (ag) to make my development workflow smoother. If you're like me and you want to respect your .gitignore while using FZF, and you also want to open files in Vim straight from FZF, here's a simple guide:

First things first, you'll need to install FZF and Silver Searcher. You can do this easily with the following command: 
sudo apt-get install fzf silversearcher-ag

Once you have these tools installed, the next step is to tweak your .bashrc file to set up the right environment variables. This ensures that FZF respects your .gitignore file by default. Open your .bashrc file with your favorite text editor:

nano ~/.bashrc

Add the following line to the file:

# For respecting gitignore
export FZF_DEFAULT_COMMAND='ag -g ""'

This command tells FZF to use Silver Searcher (ag) to list files, respecting the .gitignore.

Next, let's set up a function in your .bashrc to open selected files in Vim directly from FZF. Add this function to the same file:

# For opening vim on item selected
fzfv() {
  local file
  file=$(eval "$FZF_DEFAULT_COMMAND" | fzf) && vim "$file"
}

This function runs the FZF_DEFAULT_COMMAND, which lists all files (while respecting .gitignore), and pipes the results to FZF. When you select a file from the FZF interface, it opens in Vim.

After adding these lines, don't forget to reload your .bashrc to apply the changes:

source ~/.bashrc

Now, whenever you want to search for files and open them in Vim, you can simply type:

fzfv

This setup has made my life a lot easier, and I hope it does the same for you. Happy coding!

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.

ALTER USER 'root'@'localhost' IDENTIFIED BY '1234'; And then you need to do the flush privileges to commit previous queries (that alter command above) into the system, simply do like this. flush privileges; So now you have your root with password 1234.

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...

Spring Kafka - How to use ReplyingKafkaTemplate send and reply synchronously

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...
