AMD is hinting at officially open-sourcing its FSR 4 upscaling and frame generation technology following an accidental release earlier this year. The company's president of GPU Technologies suggested at CES that the FSR 4 Redstone technology might be open-sourced while keeping the core technology closed to avoid giving Nvidia engineers an advantage. The accidental release in August led to speculations about AMD's plans for an official open-source release, as modders quickly adapted the technology for use on older GPUs. Despite potential performance penalties, the quality of the FSR 4 model has garnered interest, hinting at a possible reemergence of the FSR 4 GitHub repository in the future.

Developer re-enables 3D printer features that Bambu Lab disabled, firm promptly threatens legal action — OrcaSlicer-BambuLab project now shuttered

Developer Pawel Jarczak voluntarily shut down his "OrcaSlicer-BambuLab" project after receiving legal threats from Bambu Lab for re-enabling 3D printer features that Bambu had disabled. Bambu Lab accused Jarczak of reverse engineering their software and violating their Terms of Use. Jarczak insists he did nothing wrong as his fork of OrcaSlicer only used publicly available source code. Bambu Lab's decision to restrict access to its cloud servers impacted users' ability to control their printers and AMS settings through OrcaSlicer. Jarczak is now focusing on developing firmware for Klipper-based printers and crowdfunding the project.

Commodore backs down over FPGA firmware lockdown — it won’t now try and block third-party firmware installs but will stand firm against bricked modded units

Commodore has reversed its decision to block third-party firmware installs on the C64 Ultimate computer, allowing users to experiment freely. However, the company will not provide support or replacements for modded units that become bricked. The initial plan to restrict non-Commodore FPGA firmware caused a divide among fans, leading to heated discussions on social media and forums. Commodore now emphasizes user freedom but warns that using community-installed firmware is at the owner's risk, with no free support or warranty service provided for damaged units.
