With Qt 6 well on its way, it’s about time we go over some of the internal changes and optimizations made to Qt 3D for the upcoming release.
In a separate article, my colleague Mike Krus has already highlighted the API changes we’ve made in Qt 3D for Qt 6. This post will dive into the internal changes.
Back in 5.14, we got rid of the Aspect Thread. Yet we still had a Render Thread. On paper, having a dedicated thread would allow you to send drawing commands to the GPU while preparing commands for the next frame. This could potentially help with maintaining a high frame rate, if command submission took a long time. In practice, this worked only in the case that Qt 3D was used as standalone (without QtQuick).

Movim: An Open-Source Decentralized Social Platform Based on XMPP Network
Just like some other XMPP desktop clients, Movim is a web-based XMPP front-end to let you utilize it as a federated social media.
Since it relies on XMPP network, you can interact with other users utilizing XMPP clients such as Conversations (for Android) and Dino (for Desktop).
In case you didn’t know, XMPP is an open-standard for messaging.
So, Movim can act as your decentralized messaging app or a full-fledged social media platform giving you an all-in-one experience without relying on a centralized network.
It offers many features that can appeal to a wide variety of users. Let me briefly highlight most of the important ones.

Patched Linux 5.11 Continues Looking Great For AMD Ryzen/EPYC Performance
While the initial AMD Linux 5.11 performance regression written about at the end of last year was of much concern given the performance hits to AMD Zen 2 / Zen 3 processors with the out-of-the-box "Schedutil" governor, with a pending patch the regression is not only addressed but in various workloads we continue seeing better performance than even compared to Linux 5.10. Here is the latest from several more days of extensive performance testing.
| DIN-rail gateway offers dual LAN and dual RS485
The Unipi Gate G110 and G100 are PLC-ready DIN-rail gateways that run Linux on a quad -A53 SoC with 16GB eMMC, GbE and 10/100 LAN ports, and up to 2x RS485 ports with modular extensions.
Czech based Unipi, which started out in 2014 with a Raspberry Pi based UniPi automation controller board and followed up with products including an Allwinner H5-based Axon automation controller, has now launched the $243 Unipi Gate G100 and $272 Unipi Gate G110 DIN-rail gateways.
