Sergey PshenichnikovSign sequences (for example, verbal and musical texts) can be turned into mathematical objects. Words and numbers have become one entity, a representation of a matrix unit, which is a matrix generalization of integers and a hypercomplex number. A matrix unit is a matrix in which one element is equal to unit, and the rest are zeros.If the words of the text are represented by such matrices, then concatenation... Read more ›

Эта публикация является развитием идей, сформулированных в предыдущей статье - "Идентификация пользователей в Web 3.0". После предыдущей публикации я понял, что в массах нет однозначного определения, что же именно называть Web 3.0 - виртуальную реальность, интернет вещей или децентрализацию на базе блокчейна. С моей точки зрения, Web 3.0 - это архитектура веб-приложений, обусловленная спросом пользователей на конфиденциальность их собственных данных. Развитие идей Web 2.0 привело к тому, что пользователи са Read more ›

![[Translation] Старая ошибка Unix, которую вы можете совершить при сигнале init (PID 1)](https://times42.com/media/3/8/0/7765380_640x200.jpg "[Translation] Старая ошибка Unix, которую вы можете совершить при сигнале init (PID 1)")
Init — традиционное имя для программы, которая выполняется как process ID 1, главный наследник всех процессов Unix, исторически отвечающий за управление системой. Process ID 1 настолько критичен для системы, что его или невозможно убить, или система перезапускается при выходе из него (или и то, и другое, тогда этот перезапуск — хак). Сегодня в Linux PID 1 необязательно оказывается двоичным файлом и процессом с именем init в буквальном смысле, в отличие... Read more ›
