1. There is no memory safety without thread safety Total comment counts : 30 Summary The article discusses the concept of memory safety, emphasizing that it often refers to preventing use-after-free and out-of-bounds accesses. However, the author argues this distinction between memory safety and thread safety is misleading; the real goal is to avoid Undefined Behavior. Through a Go programming example, the article illustrates that Go’s concurrency model can lead to memory safety violations despite being labeled memory-safe....

1. CARA – High precision robot dog using rope Total comment counts : 42 Summary CARA (Capstans Are Really Awesome) is an advanced quadrupedal robot designed without gears or pulleys, using capstan drives for its joints. Building on past designs, CARA uniquely leverages capstan drives, which provide high torque, zero backlash, and quiet operation. Achieving an exact 8:1 gear ratio required precise calculations of effective drum diameters. The robot’s legs utilize a 5-bar linkage system for compactness and load distribution, powered by BLDC motors and controlled using ODrive controllers....

1. Qwen3-Coder: Agentic coding in the world Total comment counts : 32 Summary Today, Qwen3-Coder was launched, featuring its most powerful variant, Qwen3-Coder-480B-A35B-Instruct, a 480B-parameter code model that excels in coding and agentic tasks. It supports a context length of 256K tokens and achieves state-of-the-art results in several agentic coding tasks. Alongside, the open-sourced Qwen Code tool enhances its capabilities. Leveraging Alibaba Cloud, the model encapsulates advanced reinforcement learning for real-world software tasks....

1. Global hack on Microsoft Sharepoint hits U.S., state agencies, researchers say Total comment counts : 49 Summary error Top 1 Comment Summary The article critiques the persistent issues of government breaches and stagnant security technology, specifically focusing on SharePoint. It notes that SharePoint’s popularity stems from being bundled with Microsoft products and the high cost of replacing entrenched systems. Security often takes a backseat to cost and convenience for large companies....

1. XMLUI Total comment counts : 92 Summary Jon Udell introduces XMLUI, a new project that brings the Visual Basic-style component-based development model to the modern web using React. XMLUI allows users to create apps with minimal coding, leveraging a suite of components defined through simple XML markup. This approach makes building reactive, interactive applications accessible to those without deep knowledge of React or CSS. By combining familiar concepts from earlier programming environments with contemporary technology, XMLUI aims to simplify app development and enhance productivity, leveraging tools like AI assistants to streamline coding processes....

1. Asynchrony is not concurrency Total comment counts : 35 Summary The article discusses the crucial distinction between asynchrony, concurrency, and parallelism in programming. Asynchrony allows tasks to run out of order correctly, while concurrency enables multiple tasks to progress simultaneously, and parallelism allows for actual simultaneous execution. The author highlights that misunderstanding these terms has led to inefficiencies and complexities in software development, such as duplication of effort in libraries and poor user experiences....

1. Hand: open-source Robot Hand Total comment counts : 22 Summary The project aims to create a cost-effective, dexterous robotic hand (Amazing Hand) for the Reachy2 robot, utilizing parallel mechanisms and controlled by SCS0009 servos. It includes detailed documentation, assembly guides, and control options (Python and Arduino). Custom 3D printed parts and calibration scripts are provided, with considerations for left and right hand configurations. Users need an external power supply for the servos....

1. Altermagnets: The first new type of magnet in nearly a century Total comment counts : 22 Summary Researchers have discovered a new type of magnet called “altermagnets,” marking the first novel magnetism in nearly a century. Inspired by M.C. Escher’s artwork, Libor Šmejkal predicted their existence in 2022. Unlike traditional ferromagnets and antiferromagnets, altermagnets could enable faster, more energy-efficient computing. They possess unique properties derived from the behavior of electron spins, challenging established magnetism models....

1. LLM Inevitabilism Total comment counts : 132 Summary The article discusses the concept of “inevitabilism,” a worldview suggesting that certain futures, like the rise of AI, are unavoidable and should be embraced. The author recalls advice from a debate champion friend about framing discussions on one’s own terms. Influential tech figures present AI’s advancement as inevitable, shifting the focus from “is this the future you want?” to “how will you adapt?...
