Recently, we have been using Perfetto to successfully profile Apitrace traces in crosvm through VirGL renderer. We have now added perfetto instrumentation to VirGL renderer, Mesa, and Apitrace to see what happens precisely in a frame.

As part of a project backed by INVEST-AI, a program managed by IVADO Labs, we have developed a multi-stage neural network-based solution that accurately locates and tracks the hands despite complex background noise and occlusion between hands.

Over the past few months, I've been working on a side project to improve Meson sub-project support. The best stress test is to build projects on Windows, without msys2, because it has no dependencies or tools installed (e.g. pkg-config).

In the embedded world, many modern SoCs such as the ST Microelectronics STM32MP1 now include coprocessor cores which can be used for a wide range of tasks and can offload some of the work from the main processor.

Earlier this week, WebRTC became an official W3C and IETF standard. GStreamer has a powerful and rapidly maturing WebRTC implementation. So, the obvious question is: how do we build this on Windows?
