SiFive, an important player in the RISC-V scene, recently presented their P870 core at Hot Chips 2023. The P870 is a six-wide core with out-of-order execution and aims to achieve higher performance than previous SiFive designs. It includes modern features such as a decoupled branch predictor, non-scheduling queues, and vector execution capability. Notably, the P870 […]

California state Sen. Aisha Wahab has introduced a bill to outlaw caste discrimination in the state, a proposal that has received both support and backlash. If the bill passes, California would become the first state to explicitly outlaw caste-based discrimination. Critics argue that such a ban stigmatizes the South Asian and Hindu communities and that […]
In the early 1950s, scientists began to understand the multistage process of memory formation through their studies of a patient known as H.M., who had his hippocampus removed to treat seizures. Although H.M. retained his childhood memories and other details of his life, he lost the ability to create new long-term memories. This discovery led […]
Liquid Types are a tool that enriches existing type systems by allowing programmers to specify and verify semantic properties of their code. Unlike traditional type systems that reason about the structure of program values, Liquid Types also consider the semantics of values. This means that Liquid Types can statically catch semantic type errors, such as […]
In this web content, the author discusses the controversy surrounding the legacy of Henry Cort, an inventor known for his contributions to the iron industry during the Industrial Revolution. A new paper by Jenny Bulstrode argues that Cort actually stole his innovations from black slaves who developed them independently in Jamaica. However, another scholar, Oliver […]
In this web content, the author discusses a clever trick that has been used for at least 35 years, which involves leaving array values uninitialized and then reading them during normal operations. This trick allows the code to behave correctly regardless of what garbage is present in the array. The use of uninitialized memory may […]
It’s an exciting time for GUI development in Rust, as the ecosystem now offers several well-written windowing libraries. The leading library is winit, which has excellent platform support and recently merged keyboard support. Other contenders in the space include egui, a good immediate mode GUI library, and iced, a popular retained mode library used by […]
WiiLink is a service that brings back various channels for the Nintendo Wii. They have successfully resurrected Japanese exclusive Wii channels that were previously shut down, such as Wii no Ma, the Demae Channel, and Digicam Print Channel. This means that players can once again experience these channels on their Nintendo Wii, even if they […]
This blog post discusses the theoretical background and technical implementation of cola, a text CRDT (Conflict-free Replicated Data Type) for real-time collaborative editing written in Rust. The first part of the post covers how to represent the state of the document and the edits that transform it in a way that guarantees convergence across all […]
Scientists at the University of Sydney have achieved a world-first experimental result by using a quantum computer to slow down a chemical reaction process by a factor of 100 billion times. The researchers were able to directly observe the interference pattern of a single atom caused by a common geometric structure in chemistry known as […]
