Ему была видна задняя дверца: как это принято в Севилье, она оставалась открытой - экономичный способ кондиционирования.

У сотрудников лаборатории систем безопасности была единственная обязанность - поддерживать ТРАНСТЕКСТ в чистоте, следить, чтобы в него не проникли вирусы. Он знал, что пятнадцатичасовой прогон может означать только одно: зараженный файл попал в компьютер и выводит из строя программу. Все, чему его учили, свидетельствовало о чрезвычайности ситуации. Тот факт, что в лаборатории систем безопасности никого нет, а монитор был выключен, больше не имело значения. Главное теперь - сам ТРАНСТЕКСТ.

Технология развивается в геометрической профессии, и рано или поздно алгоритмы, которыми пользуется общество, перестанут быть надежными. Понадобятся лучшие алгоритмы, чтобы противостоять компьютерам завтрашнего дня. - Такова Цифровая крепость. - Конечно.
