Deskflow is a cross-platform input multiplexer that enables the use of a single mouse and keyboard to control multiple computers. By routing input signals over a local network, it functions as a software-based replacement for physical hardware switches, allowing users to manage several systems as a unified workstation environment. The software operates using a client-server topology where a central controller manages input focus and connection state across remote nodes. It normalizes disparate operating system input APIs into a unified format, enabling consistent cursor movement and periphera

HertzBeat is a real-time observability platform that provides agentless monitoring for servers, databases, and networks. It functions as an infrastructure alerting manager, an OpenTelemetry Protocol log aggregator, and a public status page generator. The platform integrates an analysis engine that uses large language models to process monitoring data and generate system insights. It utilizes a cloud-edge collaborative architecture and distributed collector clustering to scale data gathering across large-scale networks. The system covers a broad range of observability capabilities, including

Terrain Analysis Using Digital Elevation Models (TauDEM) software for hydrologic terrain analysis and channel network extraction.

Indexes points and lines and generates map tiles to display them

Netdata is a real-time infrastructure monitoring tool and multi-node observability platform. It functions as a high-resolution monitoring agent, log and metric aggregator, and time-series database designed to provide full-stack visibility into server health. The system is distinguished by its per-second metric sampling and zero-configuration auto-discovery, which allows for immediate infrastructure tracking upon installation. It utilizes edge-based machine learning and unsupervised models to detect system anomalies and abnormal metric patterns locally on each node. For distributed environment

Tiny header-only C++17 library for lat/lng geometry: distance, bearing, area, point-in-polygon and path proximity

GNU Radio is an open-source software-defined radio framework that provides a digital signal processing toolkit for building wireless communication systems. At its core, it uses a block-based flow graph architecture where pre-built signal processing blocks are connected into directed graphs to define and execute custom radio signal processing pipelines. The system operates as a flow graph signal processor that enables low-latency streaming radio signal processing, supporting both real-time operation and wireless communication simulation entirely in software. The framework distinguishes itself

Computational geometry and spatial indexing on the sphere

Gqrx is a software defined radio application used to capture and demodulate radio signals across various frequencies to produce audio and visual data. It translates raw radio waves into audible sound using standard modes including AM, FM, SSB, and CW. The project provides tools for radio signal analysis through real-time frequency plots and waterfall displays. It enables the capture of raw baseband data and received audio for offline playback and technical analysis. The software includes capabilities for tuning radio frequencies, filtering signal noise via band-pass filters and gain control,
