In the world of Java with Spring, annotations play a crucial role in defining configuration and behavior. Here are some key points that I’ve learned over my years of experience:
@Component: Marks a class as a Spring-managed component. It's a generic stereotype. @Service: Specialized annotation for service layer components. @Repository: Indicates that a class provides the CRUD functionality of an entity. @Controller: Used in MVC patterns for web applications to handle requests.
When using these annotations, Spring manages the class lifecycle. This means you don’t need to instantiate your objects manually! Just think about it:
@Component public class MyComponent { // Class contents here }
Remember, these annotations enhance modularity, making your code cleaner and more maintainable! 🔧✨
With a solid understanding of these concepts, you can leverage Spring’s full power in your projects! Let’s keep coding! 💻

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
Telegram announces Anonymous Admins
The cloud-based messaging platform is also adding Anonymous Group Admins feature. As per Telegram, this feature is being introduced for safer protests. As per the Telegram blog post, users can “Toggle Remain Anonymous in Admin rights to enable Batman mode. The anonymized admin will be hidden in the list of group members, and their messages in the chat will be signed with the group name, similar to channel posts.”
