A free x86 emulator for Raspberry Pi

It is an emulation layer that allows you to run programs compiled in IA32 and x64 on an ARM processor. The developer who is leading the project has achieved a performance of 80% of native performance in certain games.

Setting up a gaming mouse in Linux

Piper is a tool made with GTK+ that allows you to configure a multitude of options specific to these mice.

Ray Tracing on ARM

Nvidia has made a demonstration of the real-time lighting technique along with DLSS on an ARM platform.

A4 5000

Someone has brought us this APU with Jaguar architecture from 2013. It is the model in AVX mode that has the worst scores in all single-thread tests and in one of the multi-thread tests. Of the two processors of the architecture that we have, it is in second place, not too far from the other model. It would need to multiply its performance by seven to be in the 100th position in the general ranking. In its favor, it has a TDP of 15W but with those scores, it is also not good enough to enter the Performance/W ranking.

The EVGA RTX 3090 has come out defective

The manufacturing defect was discovered when a large number of people saw that their GPUs were burning out when playing New World, which also has a defect. The game has no limitation on the frame rate on the menu screens, which can generate more than 9000 fps. And that is what has pushed the RTX 3090 to the limit until it burns out.

ARM manufactures a processor without silicon

In association with PragmatIC, ARM has created a microcontroller using the M0 repertoire. It is a processor that runs at 30kHz and consumes 21 milliwatts. The material used to replace silicon has been plastic.

The challenges of microLED

In this article, they explain the paths that have been taken in the development of this technology and the steps that remain for the technology to be manufacturable on a large scale.

MacOS in Linux with Qemu

Someone has created a series of scripts to facilitate the installation and execution of Apple's operating system on Linux.
