Researchers at UCLA have published a technical paper titled “Massively parallel and universal approximation of nonlinear functions using diffractive processors,” showcasing a novel approach to implementing nonlinear functions optically. By utilizing optimized diffractive processors with passive phase-only surfaces, large-scale nonlinear computation can be achieved using linear optics. This framework allows for the parallel computation of one million distinct nonlinear functions at wavelength-scale spatial density, demonstrating the potential for diffractive optical processors to serve as a scalable platform for universal nonlinear function approximation. The research also successfully approximated 35 unique nonlinear functions experimentally, showcasing the capabilities of this optical computing system.

Slimline Commodore 64C Ultimate Edition computers go up for pre-order — firm reintroduces the C64’s sleeker 1986-1994 styling across the range

Commodore is reintroducing the C64C Ultimate Edition computers, featuring the sleeker 1986-1994 design, available for pre-order starting at $299. The new C64C models will be made using original injection molds and tooling from the 1980s. These machines will offer the same high-performance recreation of the original Commodore 64 using FPGA technology. Additionally, different editions like BASIC Beige, Starlight, and Founder's Edition will be available for pre-order, with shipping expected to begin in late 2026. Commodore hints at more retro tech initiatives to come in 2026.

China announces CPU-only exascale supercomputer with 47,000 homemade processors, record 2 Exaflops of performance without GPUs — Lingshen super said to use Huawei Kunpeng servers and no foreign-made components

China announces CPU-only exascale supercomputer with 47,000 homemade processors, record 2 Exaflops of performance without GPUs — Lingshen super said to use Huawei Kunpeng servers and no foreign-made components

China's National Supercomputing Center in Shenzhen unveiled the Lingshen supercomputer project, aiming for over 2 ExaFLOPS performance using 47,000 homemade processors without GPUs or foreign components. The system, designed to surpass the current fastest supercomputer, El Capitan, would utilize Huawei Kunpeng servers and Arm-based Taishan cores. The project includes a pilot phase with 100 servers and a full production system with 1,580 blade servers. While China's claims of achieving 2+ ExaFLOPS are ambitious, questions remain about the feasibility of surpassing existing supercomputing benchmarks without GPUs or foreign-made CPUs.

Scientists create electronic devices that function reliably at extreme temperatures from 500 degrees Celcuis to absolute zero — advanced semiconductor material unlocks new possibilities in space tech and quantum computing

Scientists at KAUST have developed electronic devices made of gallium oxide that can function reliably in extreme temperatures from near absolute zero to 500°C. These devices have potential applications in space tech and quantum computing due to their ability to withstand extreme temperature swings. By using ultrawide-bandgap semiconductor beta-gallium oxide and heavily doping it with silicon atoms, the researchers created devices that can maintain electrical conduction even in cryogenic conditions. The team built transistors and logic inverters that operated reliably at temperatures as low as 2K, paving the way for the development of temperature-resistant devices for various technological applications.
