Erik Elfstrom writes about OrcSDR, an open-source standalone SDR application designed for the M5Stack Tab5 / ESP32-P4 and compatible with the RTL-SDR Blog V4. Unlike traditional setups that require a PC or Raspberry Pi to act as a host, OrcSDR allows the microcontroller itself to handle radio functions, DSP, graphics, audio, storage, and the touchscreen interface. This creates an efficient, low-power, and self-contained portable radio appliance capable of single-channel decoding for various modes such as FM, ADS-B, P25, LoRa, and more.
- The ESP32-P4 handles USB host communication with the RTL-SDR Blog V4 directly.
- Dedicated screens are available for FM, P25, ADS-B, LoRa, RF analysis, and 2.4 GHz Wi-Fi analysis.
- Includes advanced visualization features like I/Q constellation, phosphor persistence, and a 3D spectrum history.
- Features a serial command interface allowing control via scripts or automation in addition to the touchscreen.
- The underlying driver was developed by analyzing USB traffic from known desktop software using Wireshark.

Y Combinator is open-sourcing an agent harness called QM (short for quartermaster) designed to manage a fleet of agents for startups and YC employees. The system aims to provide flexible, easy-to-administer tools that can be used as personal assistants or assigned to specific projects to handle work-related tasks.
- It is intended to allow every employee and project to have their own agent as needed.
- This follows previous internal experiments with Ruby-based loops and Hermes agents.
- The codebase is available at github.com/yc-software/qm.

The QM repository provides a multiplayer agent harness designed specifically for startups, allowing multiple employees to have isolated workspaces while still collaborating via Slack or web interfaces. The system is built with an architecture that separates the core logic from specific model harnesses and deployment configurations, enabling users to switch between various providers like Claude Code or Codex without being tied to a single vendor. It offers tiered security postures—ranging from strict human approval for all tools to high-speed autonomous operation—and supports background work through scheduled crons and webhooks.
- Supports multiple backends including Pi, OpenCode, Codex, and Claude Code.
- Offers three distinct security modes: Strict (human intervention required), Auto (AI-driven screening), and Dangerous (no screening).
- Provides per-scope memory, files, keychain views, permissions, and durable sandboxes for each user or room.
- Includes an "individual auth" feature where users can connect their own AI accounts to keep usage credentials separate from the organization's shared keys.

Joe Brockmeier writes about the CrossPoint Reader project, an MIT-licensed initiative aimed at providing high-performance replacement firmware for small, inexpensive ESP32-based e-readers. The project seeks to overcome the limitations of stock manufacturer firmware by improving EPUB rendering, adding features like offline dictionary support and web-based file management, and enhancing overall usability without introducing resource-heavy applications.
- Version 1.5.0 introduced improved CJK (Chinese, Japanese, Korean) text rendering and right-to-left support.
- The firmware includes a built-in web server for easy wireless file transfers via HTTP.
- A Calibre plugin is available to optimize EPUB files specifically for the hardware's memory constraints.
- The project supports reading progress synchronization through KOReader protocols or Hardcover service integration.

Zoe Skyforest writes about a collation by Ian Y.E. Pan of Emacs appearances in popular culture, spanning films, TV, anime, and comics. The list highlights how the classic *nix text editor has become a recognizable cultural touchstone alongside its rival vi, though it is acknowledged to be far from exhaustive.
- In *The Social Network*, Zuckerberg uses Emacs to write a website scraper
- *Silicon Valley* features Emacs more than once
- Japanese anime *Key The Metal Idol* includes an Emacs reference
- Hackaday invites readers to submit a similar list for vi

Co11ateral writes about ShadowBroker, an open-source OSINT dashboard that aggregates live public intelligence feeds—aircraft and maritime tracking, satellite orbits, conflict reporting, GPS jamming, and more—into a single interactive map running locally via Docker. Built with Next.js, MapLibre GL, and a Python/FastAPI backend, it consolidates what would otherwise require juggling dozens of tabs into one prioritized view accessible at localhost:3000.
- Optional API keys enhance data; a language model agent can be attached to find correlations across feeds
- Telegram-sourced intelligence appears as red clusters on the map, often with attached media
- NASA VIIRS Nightlight and daily satellite captures are available as toggleable layers
- Antennas and Metastatic nodes are included, with the ability to tune in or send a message
- The project has been actively maintained for about six months with ongoing feature additions

Luke James writes that California's legislature has passed Assembly Bill 1856, which provides an exemption for open-source operating systems from the state's Digital Age Assurance Act. The bill, which was amended by the Senate before passing with a unanimous vote in both chambers, ensures that software distributed under licenses like GPL, MIT, BSD, and Apache is not required to collect user age data during setup. This decision resolves uncertainty regarding whether Linux distributions or SteamOS would need to implement mandatory age verification alongside major platforms like Windows or macOS.
- The exemption applies because these open-source licenses allow recipients to copy, redistribute, and modify the software.
- Software components such as libraries and dependencies distributed through package managers (e.g., apt or pacman) are also excluded from being classified as "applications" under the law.
- Browser extension stores are carved out because they distribute add-ons that run within a host application rather than acting as standalone executables.
- The amendments removed a problematic definition of "user" that would have technically classified every device owner in California as a child.

OpenReview is a self-hosted GitHub App developed by Vercel Labs designed to act as an automated assistant for pull request reviews. Triggered by mentioning `@openreview` in a PR comment, the tool uses Claude Sonnet 4.6 via the AI SDK to spin up isolated sandboxed environments where it runs actual project tooling ''such as linters, formatters, and tests'' to provide actionable suggestions or direct code fixes. It is deeply integrated with Vercel's infrastructure, utilizing Vercel Workflows for orchestration and Vercel Sandboxes for execution.
- Users can approve or reject agent suggestions using emoji reactions
- The bot supports custom review "skills" which can be added by placing files in a `.agents/skills/` directory within the repository.
- It requires integration with Upstash KV for storage during deployment on Vercel.
- The project is currently in beta and was originally built as an internal tool for the Vercel team.
