After Epic released the UE5 technology demo at the beginning of 2021, the discussion about UE5 has never stopped. Related technical discussions mainly centered on two new features: global illumination technology Lumen and extremely high model detail technology Nanite. There have been some articles [1 ][2] analyzing Nanite technology in more detail. This article mainly starts from the RenderDoc analysis and source code of UE5, combined with some existing technical... Read more ›

OverviewSometimes all of us need to make a graphical installer for one's own linux distro. It goes without saying that you are able to use a distro-specific installer like Anaconda for RedHat-based or DebianInstaller for debian-based. On the other hand Calamares is a graphical installer which is not aligned with only one package manager.I want to share my experience how to make a universal install solution with GUI. I did...

Lumen is UE5’s GI system, it is different from the traditional real-time GI which only includes the contribution of indirect diffuse reflection. It also includes indirect diffuse reflection and indirect highlight, providing a new set of complete indirect lighting. Lumen supports both hardware-based RTX and software-based Trace algorithms. The starting point of this article is that Lumen GI uses the process, algorithm, and data structure analysis of indirect diffuse reflection... Read more ›

![[Translation] URL Search Params](https://times42.com/media/0/3/7/3946037_640x200.jpg "[Translation] URL Search Params")
Somehow I saw code in the project of a neighboring team that generated a string with URL parameters for subsequent insertion into the iframesrc attribute.This article may seem superfluous, obvious or too simple, but since this occurs in wildlife, you should not be silent about it, but rather share best-practices.

Today, we will share some knowledge points related to resource memory leak. A memory leak is the most common issue that we continuously see and also are afraid of. What is the reason behind it? Because we can’t predict the extent of the leak before we locate the leak bottleneck, we had no idea whether it will burst out at a certain moment on the line. We have received feedback...

The Real-Time Clock (RTC) Calendar Registers in STM32 microcontrollers implemented in Binary Code Decimal format (BCD) i. e., every two digits are represented by one byte (low digit in 0-3 bits and high digit 4-7 bits). At least there are 5 bytes required to store date and time data in a such format. There are cases when memory allocation for time stamp might become critical, e. g., the events log... Read more ›

The spread of cryptocurrencies contributed to the development of many solutions based on a distributed ledger technology (blockchain). Although the scope of these solutions varies, most of them have the same basic set of security services, i.e. confidentiality, authenticity, and integrity. These features are granted by the practical applications of public key cryptography, in particular, digital signature (DS). But unlike many other applications of public key cryptography, cryptocurrency networks do... Read more ›

If you regularly use a static code analyzer, you can save time on guessing why the new code doesn't work as planned. Let's look at another interesting error — the function broke during refactoring, and no one noticed that. No one — except for PVS-Studio that can automatically scan the project and email the report to us. Read more → Read more ›

In the green energy field, the solar panels composed of bendable solar cells tend to significantly increase in popularity last time. The difficulty during the designing of the different devices (such as solar chargers, MPPT-controllers) emerges because of the strong lack of technical information about this kind of solar cell. In this article, the equivalent scheme of the bendable solar produced by the Sunpower company - Maxeon gen 5 and... Read more ›

Introduction.This is the translation of my article about ECS. Original (in Russian): https://habr.com/ru/sandbox/166093/ECS (Entity Component System) is an architectural pattern used in game development.In this article, I am going to describe some of the general principles of ECS frameworks' inner workings and some of the problems I have faced during the development of my own.When I first started learning about ECS everything seemed wonderful, but only in theory. I needed... Read more ›

Почти 3 года назад вышла статья Онлайн-конструктор переговорной комнаты — подбор оптимального решения ВКС, в которой рассказывается о решении задачи выбора оборудования для переговорных комнат используя простое 2D-моделирование и цветные диаграммы. Решение получилось простым и технически закрывает вопрос подбора оборудования. Но визуальное представление результата подобного проектирования не всегда бывает достаточно информативным для представителей заказчика.Поэтому, мы решили развить тему проектирования пе Read more ›
