8 min readCustom annotations in Kotlin allow you to define your own metadata that can be attached to code elements such as classes, functions, properties, or parameters. These annotations can be used to provide additional information or instructions to tools, libraries, or frameworks at compile-time or runtime.To create and use custom annotations in Kotlin, follow these steps:Create a new Kotlin file or open an existing one where you want to define your annotation.

8 min readConfiguring HTTPS for a Dockerized application involves a few steps:Generate or obtain an SSL certificate: You need an SSL certificate to enable HTTPS. You can either generate a self-signed certificate or obtain one from a trusted certificate authority (CA). Prepare the certificate for use with Docker: Convert the certificate and private key into the required format, such as PEM.

3 min readTo search for a string in a file using Bash, you can make use of various commands and techniques. One common approach is to use the grep command, which stands for "global regular expression print."You can use the following command syntax to search for a string in a file: grep "string" file_path Here, "string" represents the text you want to search for, and file_path is the path to the file in which you want to search.

10 min readTo renew an expiring SSL certificate, you need to follow a few steps:Check the expiration date: Identify when your SSL certificate is set to expire. This information is usually available from your SSL certificate provider or in your certificate management system. Generate a certificate signing request (CSR): Using your server's software or your hosting provider's control panel, generate a CSR for the SSL certificate renewal.

5 min readUsing pipes in Bash allows you to combine commands, where the output of one command becomes the input of the next command in a sequence. This is achieved by using the "|" symbol.To use pipes, simply write the first command, followed by the pipe symbol "|", and then write the next command. The output of the first command will automatically become the input of the second command, and so on.

8 min readDependency injection is a technique used to manage dependencies between classes in an application. It allows for loose coupling between classes and promotes code reusability, testability, and maintainability. In Kotlin, dependency injection can be implemented using various frameworks and libraries, or by manually writing the code.To implement dependency injection in Kotlin, you can follow these steps:Identify dependencies: Identify the dependencies that need to be injected into classes.

8 min readTo enable HTTPS on a local development server, you can follow the steps below:Generate SSL/TLS Certificates: You'll need SSL/TLS certificates to enable HTTPS. You can either create self-signed certificates or use tools like OpenSSL to generate them. Install the Certificates: Once you have the generated SSL/TLS certificates, you need to install them on your development server.

4 min readIn Bash scripting, you can perform arithmetic operations using various built-in operators and commands. Here are the basic arithmetic operations you can perform:Addition: Use the + operator to add numbers together. For example: sum=$((4 + 3)) Subtraction: Use the - operator to subtract one number from another. For example: difference=$((9 - 5)) Multiplication: Use the * operator to multiply numbers. For example: product=$((2 * 6)) Division: Use the / operator to divide one number by another.
