In my journey as a software engineer, I've often encountered the Singleton Pattern, a key design pattern that ensures a class has only one instance and provides a global point of access to it. Here’s a quick breakdown:
Why use the Singleton Pattern? - Controlled access to a single instance - Reduced memory footprint - Easier debugging and testing
How to implement it in Java? Here’s a simple example:
public class Singleton { private static Singleton instance;
private Singleton() {}
public static Singleton getInstance() { if (instance == null) { instance = new Singleton(); } return instance; } }
Key considerations: - Make the constructor private to prevent instantiation from outside. - Use a static method to provide access to the instance.
Remember, while the Singleton Pattern can be powerful, use it judiciously to avoid creating hidden dependencies in your code. Happy coding! 🚀

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
NEWS: Telegram supports Facetime video calls NOW!
Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
