Qt → Qt/C++ - Tutorial 091. How to write a custom delegate controlling the highlighting of a row in a table
And now a short article on customizing cell behavior using delegates in a QTableView.
This article is a modification of the table behavior in one old article, namely
Qt/C ++ - Tutorial 039. How to fill a row in QSqlTableModel by the value in the column
. In fact, that old article has no effect on the contents of this article, but the table for an example will be taken from that lesson.
As the task, the color of the line was selected when the mouse cursor was over.
It will look as follows

Python 3 → Python Image Recognition with TensorFlow and Keras
Keras, python, RuCaptcha, TensorFlow
Introduction
One of the most common uses of TensorFlow and Keras is in image recognition and classification. If you would like to learn how to use Keras for image classification or recognition, this article will teach you how to do it.
Definitions
If you do not understand the basic concepts of image recognition, it will be difficult for you to fully understand the main part of this article. Therefore, before we continue, let's define the terminology.

Qt → Qt WinAPI - Lesson 010. How to check if file writing is prohibited by another process.
Surprisingly, in the course of my professional activity, I stumbled upon one interesting feature of QFile. With it, you can check whether it is possible to read or write information to a file. But at the same time, QFile ignores read and write permissions of the file if the file is opened by several instances of the same program. This means that if the file is opened in another instance of the program, then QFile will determine this file as readable or writable, and will also be able to write to the file successfully.

Django → Django - Tutorial 054. How to create a polymorphic system of dynamic widgets
The other day, I solved the problem of adding dynamic widgets on the site with the ability to add different types of widgets, as well as with the possibility of further unlimited expansion of the widget set by adding models of specific implementations.
The system is such that there is one class Widget , which, depending on the type selected when creating it, refers to a specific implementation model, for example HTMLWidgetImpl , which contains some special parameters, and also knows about its template for rendering. Widget in the site template when calling the render() method refers to the specific implementation and its method render()** through the type.
This approach allows you to write an extremely simple code for the template, as well as organize the code so that adding new widgets will consist in adding a new data model, as well as correcting a number of places in the code, or rather updating them. Which in essence will become a routine task and will remove from the programmer the need to come up with something new.
That is, in this article I want to show not only the solution to some problem at the level of program code, but also to show the approach to architecture planning when solving such problems.

Qt → Building Docker from QtCreator
Docker, Qt, QtCreator, build, cmake
На своем компьютере для разработок нажимаете Ctrl+R (Run (Выполнить)) в QtCreator, чтобы создать и запустить ваше приложение Qt. Если вы хотите запустить приложение во встроенной системе, то вы должны выполнить четыре задачи:
• Создаете кросс-приложение Qt для целевой встроенной системы в контейнере Docker.
• Останавливаете приложение в целевой системе.
• Копируете приложение с ПК разработчика в целевую систему с помощью scp.
• Запускаете приложение в целевой системе.
Хотели бы вы нажать Ctrl+R в QtCreator и заставить QtCreator выполнить для вас четыре вышеуказанных шага? Конечно, хотели! В этой статье будет рассказано как это сделать. Запуск приложения во встроенной системе будет аналогичен запуску приложения на ПК.
