В прошлом посте мне предрекли судьбу старухи у разбитого корыта. Комментаторы справедливо заметили: «Визионер без хард-скиллов - это просто мечтатель». Я обещал не спорить, а показать результат. Время пришло.Убираем лирику, достаем «мясо». Внутри - полный разбор архитектуры AI-платформы на n8n + Supabase + OpenAI: как реализовать рекуррентные платежи, SRS-систему повторений и генерацию PDF-дипломов, не написав и сотни строк кода вручную.

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.

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...
