Hey everyone! 👋 Today, I want to dive into the @Configuration annotation in Spring Framework, which is crucial for defining beans in your application.
🛠️ What is @Configuration? - It's a class-level annotation that indicates that the class can be used by the Spring IoC container as a source of bean definitions. - With @Configuration, you can define methods that create and configure objects that are managed by Spring, enhancing the flexibility of your configuration.
📌 Key Points: - Methods within a @Configuration class that are annotated with @Bean return instances of beans. - These beans are singleton by default, meaning there's only one instance per Spring container.
💻 Example: Here's a simple implementation:
@Configuration public class AppConfig {
@Bean public MyService myService() { return new MyService(); } }
In this example, the myService method returns a bean of type MyService, allowing Spring to handle its lifecycle.
🚀 Using @Configuration helps keep your code clean and modular, making it easier to manage dependencies and configurations.

Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
How Does Bitcoin Work?
Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
