1. LT6502: A 6502-based homebrew laptop Total comment counts : 19 Summary An enthusiast documents a 6502-based laptop project (PC6502). Despite joking about being crazy, they prefer a portable build to a tower of PCBs on the sofa. The post outlines simple specs and shows assembled front, rear, side, and closed views, with the main board, battery, and keyboard in a case and a BASIC-capable screen. The memory map is currently stable and hardware operates, with some extra EhBASIC commands added....

1. News publishers limit Internet Archive access due to AI scraping concerns Total comment counts : 29 Summary Publishers are recalibrating their relationship with the Internet Archive as AI models increasingly scrape training data. The Guardian found Internet Archive crawlers frequently accessed its content and began restricting access to its articles via APIs and Wayback URLs, while leaving regional and topic pages visible. The move aims to reduce IP leakage but keeps some pages accessible....

1. GPT-5.2 derives a new result in theoretical physics Total comment counts : 30 Summary error Overall Comments Summary Main point: The discussion centers on whether GPT-5.2 can autonomously discover or corroborate new results in math/physics, and how much of the process is human-guided versus AI-generated. Concern: The main worry is hype and misrepresentation of AI capabilities, including overclaiming authorship, lack of external validation, and potential misattribution or overreliance on AI....

1. Welcoming Discord users amidst the challenge of Age Verification Total comment counts : 10 Summary Matrix welcomed a surge of users after Discord announced age-verification. Matrix is an open, decentralized standard: anyone can run servers, but admins must enforce age checks where laws require. Matrix.org is evaluating privacy-preserving age-verification options (potential Premium accounts) and exploring account portability to reduce load. It isn’t yet a full Discord replacement, and some features are missing, but Matrix offers end-to-end encryption, read receipts, and an open protocol with many open-source clients....

1. Toyota Fluorite: “console-grade” Flutter game engine Total comment counts : 20 Summary Fluorite is the first console-grade game engine fully integrated with Flutter. It lets you write game logic in Dart and render multiple 3D views via FluoriteView, sharing state between Entities and UI widgets. Its data-oriented ECS is C++-based for peak performance, optimized for low-end hardware, while preserving Dart APIs for familiar development. Blender-defined clickable zones trigger onClick events to enable spatial 3D UI....

1. The Singularity will occur on a Tuesday Total comment counts : 98 Summary Argues the AI singularity could be finite and real, not merely exponential hype. The author fits five progress metrics to a hyperbolic model: y_j(t) = k_j/(t_s − t) + c_j, with a common t_s but metric-specific scales. For each candidate t_s, they measure how well the hyperbola fits (R^2). If a metric trends toward a pole, its R^2 peaks at finite t_s; if linear, it improves toward infinity....

1. America has a tungsten problem Total comment counts : 12 Summary America has a tungsten problem: the US will need far more tungsten, but currently relies on China. Tungsten is heat-resistant, very hard, dense, and conductive; key uses include oil-drilling bits and, crucially, nuclear fusion reactors (plasma-facing components and shielding). Domestic demand is about 10,000 tons/year and could rise to 15,000+ as defense and semiconductors grow. If fusion ramps up, demand could surge dramatically; rough estimates suggest tens of thousands of tons annually (e....

1. Vouch Total comment counts : 61 Summary An experimental contributor trust management system uses explicit vouches and denounces to control who can interact with parts of a project. It’s generic and usable on any code forge, with GitHub Actions and a CLI integration for GitHub projects. Vouches are stored in a simple .td (Trustdown) file, enabling a flat, easily parsed list that can form a web of trust and read other projects’ lists....

1. SectorC: A C Compiler in 512 bytes Total comment counts : 8 Summary A SectorC is a C compiler in a 512-byte x86-16 boot sector, capable of a useful subset of C and likely the smallest such compiler. To fit the tokenizer in 512 bytes, the author develops Barely C, a C-like language with mega-tokens and using atoi() as a hash-like tokenizer. The first Barely C fits in 468 bytes with a simple recursive-descent parser and no symbol table; variables are addressed by a 16-bit hash; codegen uses ax and cx....

1. The Waymo World Model Total comment counts : 42 Summary Waymo introduces the Waymo World Model, a frontier generative model for hyper-realistic autonomous driving simulation built on Genie 3. It creates vast, controllable 3D environments with multi-sensor outputs (camera and LiDAR) and can simulate rare events hard to capture on real roads. By transferring Genie’s broad world knowledge from 2D video into 3D sensor data and enabling driving action, scene, and language control, it lets Waymo exhaustively test edge cases—boosting safety and enabling scalable deployment in new cities and conditions....
