BrowSDR is a high-performance, browser-based Software Defined Radio (SDR) receiver designed specifically for HackRF devices. By utilizing WebUSB and WebAssembly, it allows users to tune into various radio modes directly within a web browser without the need for native drivers or software installation. The platform features a multi-VFO architecture for simultaneous frequency monitoring, real-time WebGL waterfall displays, and AI-powered live transcription of demodulated audio.
Key features include:
- Multi-VFO support for independent tuning and DSP settings
- High-speed signal processing via Rust and WASM
- Real-time spectrum analysis and GPU-accelerated waterfall display
- Wide demodulation support including WFM, NFM, AM, USB, LSB, DSB, CW, and raw IQ
- Built-in POCSAG decoding and RDS station information retrieval
- Remote access capabilities via WebRTC/PeerJS

Tansu, an open-source, Apache Kafka-compatible messaging broker, challenges traditional approaches by prioritizing statelessness. Instead of replicating data like Kafka, Tansu delegates durability to external storage, allowing for brokers that are lightweight ("cattle," not "pets") and scale rapidly. It supports various storage backends like S3, SQLite, and Postgres, with a particular emphasis on Postgres integration for streamlined data pipelines. Tansu also offers broker-side schema validation and the ability to directly write validated data to open table formats like Iceberg, Delta Lake, or Parquet. The project is written in Rust and seeks contributors.
One CLI for all of Google Workspace — built for humans and AI agents. Drive, Gmail, Calendar, and every Workspace API. Zero boilerplate. Structured JSON output. 40+ agent skills included.
yoagent is a simple, effective agent loop with tool execution and event streaming in Rust. Inspired by pi-agent-core. It features a stateful agent, multi-provider support, built-in tools, and context management.
A terminal tool that right-sizes LLM models to your system's RAM, CPU, and GPU. Detects your hardware, scores each model across quality, speed, fit, and context dimensions, and tells you which ones will actually run well on your machine.
This article details the author's experience with Nushell, a terminal shell that presents data in a spreadsheet-like format, improving usability and productivity compared to traditional command-line interfaces. It covers installation, core concepts, benefits for everyday tasks, customization options, and limitations.
FastCode is a token-efficient framework for comprehensive code understanding and analysis, delivering superior speed, exceptional accuracy, and cost-effectiveness for large-scale codebases and software architectures. It features a three-phase framework for semantic-structural code representation, lightning-fast codebase navigation, and cost-efficient context management.
A "Clawdbot" in every row with 400 lines of Postgres SQL. An open-source Postgres extension that introduces a claw data type to instantiate an AI agent - either a simple LLM or an "OpenClaw" agent - as a Postgres column.
