SOLID

👆 SOLID - одни из самых известных принципов для написания качественного ООП кода. Насколько бы простыми и интуитивно понятными они не казались - в своем конечном варианте они были сформулированы только в 2000м году Робертом Мартином.

👉 Я тоже считаю считаю их очень важными для написания качественного читаемого кода. Читаемость (или читабельность) - это вообще один из самых важных факторов вашего кода - ведь будь то большой проект или маленький пет-проект - вам приходится именно читать код в разы больше, чем его писать. Любой баг, любая фича, любой вопрос - это повод к тому, чтобы сесть и прочитать кусок кода.

👇 В первый раз когда я про это прочитал и осознал - у меня буквально перевернулся взгляд на то, как писать код, почему его надо писать по-другому. Итак:

🪑 SRP (Single Responsibility Principle) - Принцип единственной ответственности. О том, что каждый класс должен отвечать за одну и только одну функциональность.
🚪 OCP (Open-Closed Principle) - Принцип открытости закрытости. О том, что классы должны быть открыты для расширения, но закрыты для изменения.
👨‍👩‍👧 LSP (Liskov Substitution Principle) - Принцип подстановки Барбары Лисков. О правильном поведении при наследовании.
🧩 ISP (Interface-Segregation Principle) - Принцип разделения интерфейса. О том, как правильно использовать интерфейсы и абстракции.
🔃 DIP (Dependency Inversion Principle) - Принцип инверсии зависимостей. О правильной организации зависимостей на разных уровнях программы.

💬 В следующих постах периодически буду раскрывать подробнее что тут происходит.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
