According to the no-cloning theorem it is impossible to create an independent and identical copy of an arbitrary unknown quantum state. We cannot delete any quantum information as well. All changes in time of the state vector in quantum mechanics are described by the action of unitary operators. Accordingly, there must be an operator performing a deleting operation. The operator must be a zero matrix in order to nullify quantum... Read more ›

Всем привет! Хочу поделиться новостями о том, как развивается BI-платформа в inDriver. Сегодня расскажу, как мы внедрили программу обучения Tableau в компании, чтобы развивать нашу self-service аналитику и децентрализовать процесс анализа данных. Перед тем, как начать рассказ про наш тернистый путь из проб, ошибок и успехов, хочу сделать небольшое лирическое отступление о том, из каких больших структурных блоков состоит наша BI-платформа. Их 3 — архитектура, self-service и репортинг. Подробнее о... Read more ›

Different navigation message protocols are used for different navigation signal type. This is true even for a single system like NAVSTAR GPS. For example, L1C/A signals have a LNAV protocol, while L2C and L5 signals utilize a CNAV protocol. The newest L1C signal will use CNAV-2. The protocol defines a data distribution into frames, subframes, the subframes structure, transmission intervals, data resolution and so on. A navigation receiver use the... Read more ›

В марте 2010 года были популярны в том числе и на Хабре, бесплатные хостинги картинок: собственного сервиса habrastorage.org у сайта ещё не было, а по форумам была довольно популярной услуга — опубликовать картинку на стороннем сервисе и показать её в статье или в комментарии. Возник вопрос — много ли таких сервисов в природе, чтобы бесплатно и главное — без регистрации, позволяли бы достаточно надёжно публиковать картинки, в основном, не требуя... Read more ›

Hearing is one of the few basic senses that we humans have along with the other our abilities to see, smell, taste and touch.

And speaking makes our life so much fun, because what else can be better than... Read more ›

Уже вышла Java 18, но для всех сидящих на LTS по-прежнему остаётся актуальной версия 17. Такие люди могут не отслеживать постоянно фичи каждой новой версии, а спокойно заниматься своими делами и иногда навёрстывать сразу всё.И как раз на такое «навёрстывание» рассчитан доклад Тагира Валеева (tagir_valeev), с которым он осенью выступил на нашем мероприятии TechTrain. Люди, которые в последние годы тщательно отслеживали все новинки в Java, тут особо много нового не... Read more ›

In previous post I've described an example of kogito-based microservice on quarkus in native mode, containing one embedded pmml model with decision tree. While it can be successfully used for prototyping purposes, in the real life microservice might contain several prediction models. From the first view I've got an impression, that inclusion of several models should be a trivial extension of the prototype with one model. We were completely wrong... Read more ›

In this article there is the work with the PYD 1588 digital Infrared passive motion sensor introduced. The PYD 1588 is a serial opposed format, two element detector based on pyroceramic produced by the Excelitas Technologies. This sensor represents a low-power (3.0 uA with 1.8 V source voltage as in documentation said) passive component with two sensible elements, which measure the thermal infrared radiation stream.The signal is converted to a...
