  • NVIDIA GeForce Now quietly starts working on Linux as the Avengers come to play

    If you use or have been following NVIDIA GeForce Now, the cloud gaming platform that delivers PC titles you already own from sources such as Steam and Epic Games to a multitude of devices, the latest development seems to have emerged silently. Spotted by the team at GamingonLinux, users of Linux can now, it seems, access GeForce Now in either Chromium of Google Chrome.

    Indeed, previously this tactic involved fudging user agents to make GeForce Now believe you were on a Chromebook, following the launch of the web client for Google's laptops. And it works just fine, I logged in and played some games with no issues on Ubuntu in both browsers. And just to double check, Firefox still shows an incompatible device error.

  • Intel Compute Runtime 20.37.17906 Brings Rocket Lake Support

    Intel's software team has released a new version of their Compute Runtime that provides OpenCL and oneAPI Level Zero capabilities for their graphics hardware on Linux.

  • AMDGPU TMZ + HDCP Should Allow Widevine DRM To Behave Nicely With AMD Linux Systems

    Coming together this year for the mainline Linux kernel was the AMDGPU Trusted Memory Zone (TMZ) capability for encrypted video memory support with Radeon GPUs. This topic was talked about at this week's XDC2020 conference.

    AMDGPU TMZ prevents unauthorized applications from accessing the encrypted/trusted memory of an application. TMZ protects both reads and writes while leveraging an AES cipher. But while discrete Radeon GPUs can also support TMZ, for now the AMD Linux developers have just been focused on the capability for their APU platforms.

  • Zink OpenGL-On-Vulkan Seeing Some 50~100% FPS Gains

    After working on getting the Zink OpenGL-over-Vulkan driver up to OpenGL 4.6 with still pending patches, former Samsung OSG engineer Mike Blumenkrantz has been making remarkable progress on the performance aspect as well.

    This generic Mesa OpenGL implementation that works atop Vulkan drivers is about to see much better performance. Blumenkrantz recently commented the performance was turning out better than expected but that was for micro-benchmarks. But now with more optimizations he is achieving even better results.

  • Videoconferencing Malware, Vizom, Discovered [Ed: Wrong. Zoom itself is malware and they admit having back doors.]

    It was probably only a matter of time before the cyber attackers hit videoconferencing software in 2020. Apps such as Zoom had a bona fide boon this year because of the world health crisis. Researchers discovered a new form of malware that uses remote overlay attacks to hit Brazilian bank account holders who use videoconferencing software. [...] Phishing campaigns spread Vizom, disguising it as Zoom. Once the malware accesses a Windows computer, it hits the AppData directory to start infecting the system. Using DLL hijacking, it tries to force malicious DLLs to be loaded, using names the attackers believe are on the software directories for the Delphi-based variants.

  • Combating abuse in Matrix - without backdoors.

    Last Sunday, the UK Government published an international statement on end-to-end encryption and public safety, co-signed by representatives from the US, Australia, New Zealand, Canada, India and Japan. The statement is well written and well worth a read in full, but the central point is this:

    We call on technology companies to [...] enable law enforcement access to content in a readable and usable format where an authorisation is lawfully issued, is necessary and proportionate, and is subject to strong safeguards and oversight.
    In other words, this is an explicit request from seven of the biggest governments in the world to mandate a backdoor in end-to-end encrypted (E2EE) communication services: a backdoor to which the authorities have a secret key, letting them view communication on demand. This is big news, and is of direct relevance to Matrix as an end-to-end encrypted communication protocol whose core team is currently centred in the UK. Now, we sympathise with the authorities’ predicament here: we utterly abhor child abuse, terrorism, fascism and similar - and we did not build Matrix to enable it. However, trying to mitigate abuse with backdoors is, unfortunately, fundamentally flawed.
