A system one decision model uses a single pass to generate output by selecting the highest probability option from a constrained set, but may not guarantee accuracy. Calibrating the model's confidence scores through temperature scaling can improve its accuracy and match its true probabilities.

The original simulation combined a 2D rigid body with simple models of a car, ship and brick. It used proper rigid-body physics to handle rotation and added a vehicle simulation layer for tyres, which was an approximate but effective model at the time.
A city-building game about trying to get housing built in San Francisco. By Oliver Sin.
This project transforms the PSP 1000 into a modern handheld using a Raspberry Pi, offering various features and technical details. The PSPi 6 is an open-source hardware design available for purchase or DIY assembly.
The author proposes the "Lightbulb Computer," a device that combines a projector with computer vision, allowing users to interact with information in their real-world environment. This device aims to provide a more natural and convivial way of computing, reducing distractions and promoting social interactions.
The author uses Rewind VM to find and solve race conditions in Nix builds, leveraging Nix's deterministic nature and built-in features like derivations, debug symbols, and cache. Rewind provides a debugger-like experience with tools like gdb support, shell access, and comparison capabilities.
Researchers have developed a method to create large language models that operate directly on the byte encoding of text, avoiding the limitations of subword tokenization. This approach, called "byteification," allows for more efficient processing and better performance in domains requiring fine-grained textual understanding.
DuckDB 2.0 alpha is out, offering significant speed improvements over the previous version, especially for large data sets and recursive queries. The new features include a separate download pool for async I/O, improved handling of JSON data with VARIANT type, and enhanced triggers and query optimization capabilities.
A user found an error in Donald Knuth's book "Computer Modern Typefaces" and was confirmed by Knuth, receiving a check. The user initially waited months to report the error, even dismissing their own claim from a university genius.
Released for Hangul Day 2026: how I collected 4,500 lines of handwriting with a smartpen, adapted Alex Graves' architecture to Hangul, and published the dataset.
Talorys is a free, open-source personal AI assistant that runs on Cloudflare and provides tasks, notes, memories, reminders and routines without server or database access. It stores data in a single SQLite-backed Durable Object and has no telemetry or analytics code.
Microsoft CEO Satya Nadella calls for a more transparent AI system with tamper-proof evidence and containment technologies. He recommends assuming models are compromised and containing them from the start, like an emergency brake.
Microsoft is introducing Execution Containers (MXC) to help run and manage agents more securely, providing a policy-driven execution layer for untrusted code or dynamically generated workloads. MXC limits what the agent workload can access by containing the scope of the impact if something goes wrong.
celld is a distributed system runtime for Cloudflare Workers and Durable Objects, using deterministic simulation testing to find and fix bugs by replaying specific event sequences. The simulator controls event order and storage responses to test reliability, ensuring consistent results across runs.
Veda is an operating system with a built-in AI agent that interacts with applications and users through voice commands, providing a more intuitive and user-friendly experience. The agent is designed to be part of the system, not just an added feature.
The author discusses unikernels, a concept where an application is the operating system, and how they can improve security by reducing the attack surface. They share their experience building a distributed unikernel operating system using OCaml and agents.
A new study shows fruit and vegetable nutrient levels have dropped by up to 50% since the 1960s due to declining soil quality and selective breeding. This may require revising dietary guidelines, as people on weight-loss drugs could face higher risks of nutrient deficiencies.
Cockroach Labs' MOLT tool gained the ability to migrate from IBM Db2 sources, utilizing a hospital model for high-quality code production. The hospital model ensures thorough review and testing before merging code, resulting in significant cost savings and improved quality compared to traditional agent-based approaches.
The author feels undervalued in the industry due to the shift towards valuing programmers for high-level design and abstraction, rather than low-level details. They struggle with adapting to new technologies like LLMs that prioritize abstractions over hands-on expertise.
The author successfully decompiled a popular first-person shooter game using AI orchestration and optimization techniques, achieving 99% accuracy of the game's functions. The project taught valuable lessons on precise instructions, machine-checkable correctness, and the importance of reducing token consumption over productivity.
Diffle is a tool for reviewing Git diffs in the browser, allowing users to comment on lines, blocks, or whole files and submit them as a prompt or pending review. It can also be used to generate test cases and screenshots of code changes.
Researchers found that minimally and highly processed meals with the same nutritional profile produced distinct metabolic responses, including higher insulin release and energy expenditure in ultraprocessed meals. The study suggests that food processing affects how the body and brain respond to food beyond just carbohydrates, fat, and protein.
The author shares their experience learning C after initially being a Rust programmer, highlighting the language's quirks and differences from Rust. They provide examples of how C handles booleans, strings, error handling, arrays, and pointers to illustrate its unique features.
Rampart is an open-source browser-based tool that removes personal info from chat messages before sending. It combines deterministic rules and machine learning to protect user privacy in real-time.
