RISC-V emulator in the form of a pixel shader, enabling Linux to run in VRChat

Posted on

The results of the experiment on launching Linux within a virtual 3D space of the multiplayer online game VRChat, which allows the upload of 3D models with custom shaders, have been published. To implement the intended idea, a RISC-V architecture emulator was created, run on the GPU side as a pixel (fragment) shader (VRChat does not support compute shaders and UAVs). The emulator code is published under the MIT license. The emulator is based on […]

OpenSSL 1.1.1l update fixing two vulnerabilities

Posted on

An updated release of the OpenSSL cryptographic library 1.1.1l is now available, addressing two vulnerabilities: CVE-2021-3711 — a buffer overflow in the code implementing the SM2 cryptographic algorithm (widely used in China), which allows up to 62 bytes to be overwritten in an out-of-bounds buffer due to a miscalculation of the buffer size. An attacker could potentially achieve arbitrary code execution or crash the application by sending specially crafted […]

Release of emulator QEMU 6.1

Posted on

The release of QEMU 6.1 has been announced. As an emulator, QEMU allows running programs compiled for one hardware platform on a system with a completely different architecture, for example, executing an application for ARM on an x86-compatible PC. In virtualization mode, QEMU's code execution performance in an isolated environment approaches that of a physical system thanks to the direct execution of instructions on the CPU and leveraging […]

Release of payment system GNU Taler 0.8, developed by the GNU project

Posted on

The GNU project has released version 0.8 of the GNU Taler electronic payment system. A key feature of the system is that it provides anonymity for buyers while ensuring that sellers are not anonymous, thereby ensuring transparency in tax reporting. That means the system does not allow tracking user spending, but it provides the means to track incoming funds (the sender remains anonymous), addressing inherent […]

Ruffle integrates support for the H.263 codec, written in Rust.

Posted on

In Ruffle, the emulator for Adobe Flash Player written in Rust, support for the H.263 video compression format decoder has been added, allowing playback of video streams embedded in SWF files (currently without FLV format support). The H.263 decoder is built from scratch in Rust and is not a wrapper around FFmpeg. The codec implementation was initially proposed for inclusion in Ruffle back in January, […]
