Intro to C++ Coroutines: Concept
The time has come, fellow devs. We are on our way to uncover the newest concept of C++ language – Coroutines. They are already used by several programming languages, like C# async tasks and yield iterables, forming LINQ base; JS with awaitables, replacing the old way of making consecutive calls, that was hard to understand […]
Optimizing and Sharing Shader Structures
When writing large graphics applications in Vulkan or OpenGL, there’s many data structures that need to be passed from the CPU to the GPU and vice versa. There are subtle differences in alignment, padding and so on between C++ and GLSL to keep track of as well. I’m going to cover a tool I wrote […]
KDGpu v.0.1.0 is released a Vulkan wrapper to make modern graphics easier
We’re pleased to announce we’ve added a new library, KDGpu, to the arsenal of tools we invent to make our lives easier – and then share with you on KDAB’s GitHub. Who is this for? If you want to become more productive with Vulkan or learn the concepts of modern explicit graphics APIs, then KDGpu […]
Reverse Engineering Android Apps Join the dark side :)
Reverse engineering in general is a tricky business and sometimes not very orthodox. So, why bother to write this article? Well, sometimes reverse engineering is also for something good. It started when my wife dusted off her watch. We had a huge unpleasant surprise when we found that the companion app is not available anymore […]
New Training Course: Introduction to Rust joins the KDAB Training portfolio
We’re delighted to announce that Ferrous Systems has partnered with KDAB to offer its 5-day, on-line training ‘Introduction to Rust’ as an addition to KDAB’s regular Scheduled Training courses
Object Ownership
Last time we touched upon object lifetime and today we wrap up the basics with a bit of a spicy topic of object ownership. We covered the lifetime quirks, and we found out that manual memory management can be a nightmare, even if we new and delete in the correct order. There must be something […]
KDAB Training Day before Qt World Summit 2023 Berlin, November 27th, 2023
The KDAB Training Day will be back in Berlin on November 27th this year, right before the annual Qt World Summit, which will happen November 28-29th. KDAB Training Day will be held at the H4 Hotel Berlin Alexanderplatz, just down the road from the bcc Berlin Congress Centre where The Qt World Summit takes place, […]
Synchronization in Vulkan Learn about what Vulkan needs us to synchronize and how to achieve it
An important part of working with Vulkan and other modern explicit rendering APIs is the synchronization of GPU/GPU and CPU/GPU workloads. In this article we will learn about what Vulkan needs us to synchronize and how to achieve it. We will talk about two high-level parts of the synchronization domain that we, as application and […]
Object Lifetime
Last time we discussed Value Semantics. However, I missed one topic that is super important for a better understanding of basic building blocks of C++. Today, we are going to talk about an object. Without further ado, let’s dive deeper! Object What is an object? According to the C++ standard, part 3.9.8 under the name […]
