Технический сбой. Эволюция программиста

Сегодня случилось непредвиденное. В силу неизвестных мне причин (то ли сбой на сервере, то ли кривость FTP клиента) файл за сегодня на сервере испортился. Надеюсь, что к завтрашнему дню я все восстановлю, а пока выкладываю текст, который я недавно нашел в Интернете. Ему, насколько я понимаю, не один год, но, может быть кто-то еще не видел. Программисты оценят.
