Испания. Так вот почему Дэвид отложил поездку в Стоун-Мэнор. - Сегодня утром я послал за ним машину.

### Basic Addition and Subtraction Mix

Дэвид Беккер? - спросил один из. Беккер остановился, недоумевая, откуда им известно его имя. - Кто… кто вы. - Пройдемте с нами, пожалуйста. Сюда. В этой встрече было что-то нереальное - нечто, заставившее снова напрячься все его нервные клетки.

Несмотря на свой внушительный вид, дешифровальное чудовище отнюдь не было островом в океане. Хотя криптографы были убеждены, что система фильтров Сквозь строй предназначалась исключительно для защиты этого криптографического декодирующего шедевра, сотрудники лаборатории систем безопасности знали правду. Фильтры служили куда более высокой цели - защите главной базы данных АНБ. Чатрукьяну была известна история ее создания.

В процессе форматирования стирается память машины - информация, программное обеспечение, вирусы, одним словом - все, и в большинстве случаев переформатирование означает потерю тысяч файлов, многих лет труда. Но ТРАНСТЕКСТ не был обычным компьютером - его можно было отформатировать практически без потерь. Машины параллельной обработки сконструированы для того, чтобы думать, а не запоминать.
