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.
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 ...
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 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.
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.
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.
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.

A visual explorer for Unicode. Browse the character set, discover related glyphs, and learn more about the scripts, symbols, and shapes that make up the standard. Charcuterie is still under active development, and feedback is welcome. If you would like to support the project and help make more time for it, consider a donation.
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.

CollectWise is a Y Combinator-backed startup using generative AI to automate debt collection. They're hiring an AI Agent Engineer to build voice AI infrastructure and reach $10 million in annual revenue within a year.
It wasn't even trained specifically for cybersecurity. It's just that much better at doing work in general. Mythos can chain multiple low and medium vulns together to create a high or critical. This is a task that far less than 1% of cybersecurity experts have ever done. Hell, probably less than 1% of all pentesters. So if it can do that, how do you think it'll do at sending ...
Instant is a full-stack app builder that allows developers to create unlimited apps with real-time, offline, and fast performance, using a multi-tenant database and sync engine. It provides a range of built-in services, including auth, file storage, presence, and streams, and is designed to be easy to use and maintain, with a focus on developer productivity and scalability.
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.
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 Raft Consensus Algorithm is explained through the movie Mean Girls, where a clique of friends (the Plastics) replicates data and ensures consistency by achieving a majority vote. The leader of the clique (Regina George) sends heartbeats to maintain leadership status, and a new leader is elected when the current one is unable to assert dominance.
Afrika Bambaataa, a founding figure of hip-hop culture, has died at 68 due to cancer complications. He helped shape hip-hop as a musical genre and cultural force, but his legacy was complicated by allegations of child abuse and trafficking.
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.
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.
Hegel is a universal property-based testing protocol and family of libraries, built on Hypothesis.
Researchers reverse-engineered Google's SynthID watermarking system using signal processing and spectral analysis. They developed a multi-resolution spectral bypass (V3) that achieves high PSNR and can remove the watermark from images of various resolutions.
When we launched the OpenPolicy Astro integration in March, it worked by generating Markdown files at build time. You added the plugin to astro.config.mjs, pointed it at an output directory, and Astro imported the generated .md files as components. It worked. But it added friction: an extra package, a .gitignore entry for the generated directory, and a file-watching step between your config ...
Mechanical sympathy in software is the practice of creating systems that are sympathetic to their underlying hardware, optimizing performance by following principles such as predictable memory access and the single-writer principle. By applying these principles, developers can create surprisingly performant systems, such as the mechanically-sympathetic LMAX Architecture, which processes ...
