Researchers developed a formal model of file synchronizer behavior using Quviq QuickCheck, a testing framework that generates random test cases. The model was used to test Dropbox, Google Drive, and ownCloud, exposing unexpected behavior in two out of three systems, including situations where data could be lost.
Intel announced the 486 CPU at Comdex on April 10, 1989, priced at $950 each in quantities of 1,000. Predictions about its limited demand and high price were later proven incorrect as the 486 became a viable processor for several years.
Researchers at ETH Zurich have developed a highly stable swap gate for neutral atom qubits using geometric phases. This robust gate can be applied to 17,000 qubits simultaneously with a precision of over 99.9 percent.

The FBI recovered deleted Signal messages from an iPhone by extracting data from the device's notification database. The messages were preserved in internal memory due to the defendant's iPhone settings and iOS's data caching capabilities.
OpenAI supports Illinois state bill SB 3444, which shields AI labs from liability for "critical harms" caused by frontier models. The bill defines frontier models as those trained with over $100 million in computational costs and requires labs to publish safety reports.
The author is against the "Skills" standard for LLMs, preferring the Model Context Protocol (MCP) for service integration. MCP provides a more practical and standardized way to connect LLMs to services.
The author created a formal model of the Dungeons & Dragons game using a 6,000-line Quint spec, which was later expanded to include combat mechanics and interactions, and used a model-based testing (MBT) approach to validate the implementation against the spec. The MBT pipeline found and fixed several bugs in the implementation, including issues with spell slots, damage calculations, and ...
QVAC SDK is a universal JavaScript/TypeScript SDK for building local AI applications across desktop and mobile, built on QVAC Fabric and Bare runtime. It's open source under Apache 2.0 and comes with extensive documentation for easy development.
The user is frustrated with MacOS window management, specifically the inability to instantly switch spaces without animation. They found a solution called InstantSpaceSwitcher, a menu bar app that achieves instant space switching without drawbacks.
Scientists used leg bands with chemical sensors on 54 Magellanic penguins to detect pollutants in their environment. The study found PFAS in over 90% of the bands, revealing exposure to pollutants in a remote region.
NASA's Artemis II mission is testing radiation protection for humans beyond Earth's magnetic shelter, measuring how radiation levels change with trajectory and shielding. The mission will lay the foundation for safe human exploration of the Moon and Mars by characterizing the radiation field inside the spacecraft and linking it to biological effects.
Caffeine's effects last longer than assumed due to its conversion into paraxanthine, which blocks adenosine receptors. Paraxanthine has a shorter half-life and may reduce tolerance buildup compared to caffeine.
The skill declares its own allowed-tools, but Claude Code may still prompt you to approve each Bash call. To avoid repeated prompts, copy the absolute paths to the scripts from the installed skill and add them to your .claude/settings.json (project-level) or ~/.claude/settings.json (global):
GitButler, a tool for software development, has raised $17M in Series A funding to redesign the way developers collaborate. The goal is to create a more social and intuitive platform that removes friction from collaboration and integrates AI tools seamlessly.
Keeper is a Go library for a hardened secret store with four security levels, per-bucket DEK isolation, and a tamper-evident audit chain. It uses Argon2id key derivation and XChaCha20-Poly1305 authenticated encryption.
ChatGPT is testing ads in the US, starting February 9, 2026, for Free and Go users, excluding Pro, Business, Enterprise, and Edu accounts. Ads are separate from ChatGPT's responses and do not influence answers.
The user has been making generative art since 2016, starting as a programming exercise and evolving into a personal journey of self-expression and discovery. Through experimentation and learning various algorithms and techniques, the user has developed a "vocabulary" of creative tools that inform their artistic decisions and help them convey a personal aesthetic.
Discussion: In the late 1980’s Gary Miller and Michael Rabin came up with their now-famous Miller-Rabin primality test. See Wikipedia and my 2013 Program Gallery entry. It was notable in that it provided a randomized algorithm to check if an integer is prime, which had a tunable parameter to increase the probability of being correct. The intervening 40 years has seen a huge body of research ...

Kagi's URL Redirects allows users to control search result URLs by setting up textual find-and-replace rules. This feature lets users redirect URLs to preferred versions of websites or domains.
A coding agent was used to optimize the performance of the llama.cpp neural network model, resulting in a 15% speedup on x86 and 5% speedup on ARM. The agent's success was due to its ability to read papers and study competing projects before writing code, allowing it to identify optimizations that code-only agents would miss.
The picoZ80 is a custom PCB designed to replace a physical Z80 in a host or industrial computer with a faster CPU, more memory, virtual devices, networking, and rapid application loading from an SD card. It hosts an RP2350B microcontroller, a dual-core 150MHz Cortex-M33 device capable of running at up to 300MHz, and an ESP32 co-processor for WiFi and Bluetooth connectivity.
The author has concerns about having a smart robot, Mabu, in their home due to potential surveillance, data misuse, and hacking risks. They mitigate these concerns by controlling the recording feature and regulating interactions between Mabu and their children.
