There is a list of well-known electronics design tools for Android which can be found in every review for the last 10 years: “Electrodoc”, “Every Circuit”, “Droid Tesla”, “Electronics Toolbox”, “RF & Microwave Toolbox” and so on. Also, there is a lot of trash on the market that turns finding a good tool into a quest.This short review is about an unknown but cool tool “Circuit Calculator” working on Android... 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 ›

My gut feeling told me, there were... 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...

Queries in PostgreSQL. Sequential scanIn previous articles we discussed how the system plans a query execution and how it collects statistics to select the best plan. The following articles, starting with this one, will focus on what a plan actually is, what it consists of, and how it is executed.In this article, I will demonstrate how the planner calculates execution costs. I will also discuss access methods and how they... Read more ›

This article describes how to develop a real-time weather prediction app in Flutter using the Tomorrow.io Weather API. The app consists of a single screen that displays the current weather and a 4-day daily forecast for a specific location. We’re creating this prediction app on Flutter because it is an open-source UI development kit, which means it can be integrated beautifully into desktop and mobile apps across various platforms, making...

Once a upon a time I moved to brand new project. And without much thought, I decided to take DevOps responsibilities (after a long period of Frontend). Huge mono-repository (Angular and Node.js) gives rise to many specific problems. And this project was no exception. At the very beginning CI/CD duration was about 1.5h. And that was the biggest problem to take care of.But at first, I want to talk about... Read more ›
