❓ Что такое полиморфизм?

Полиморфизм — это способность объектов разных классов, связанных через наследование или интерфейсы, реагировать на один и тот же вызов метода по-разному.

Достигается через переопределение методов (runtime polymorphism) и перегрузку методов (compile-time polymorphism).

Основной тип полиморфизма — динамический (runtime), когда метод вызывается в зависимости от реального типа объекта во время выполнения, а не от типа ссылки.

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.”

What is Telegram?

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
