Исходники Facebook просочились в Сеть

Вы давно хотели увидеть исходный код одного из самых успешных проектов Веб 2.0? Ну вот, сегодня как раз тот день, когда вы можете посмотреть на работу «лучших PHP-программистов мира».

Вчера из-за небольшого глюка на сервере Facebook исходный код первой страницы этого социального сервиса стал виден небольшому количеству пользователей. Самые умные из них сделали копию, так что сейчас исходники выложены на всеобщее обозрение.

Компания Facebook уже подтвердила утечку информации, так что это настоящий код, а не подделка.

Впрочем, ничего особенного в коде нет, это стандартный PHP-код. Независимые программисты уже давно изучили и Facebook, и другие сервисы Веб 2.0, так что на чёрном рынке вы можете без проблем купить клон того же Facebook за $200.
