p-queue is a JavaScript promise queue and concurrent task scheduler designed to limit the number of active asynchronous operations. It serves as an asynchronous rate limiter and promise lifecycle manager to prevent resource exhaustion. The project distinguishes itself through priority-based task scheduling and token-bucket rate limiting to control execution frequency. It integrates with abort signals for task cancellation and provides mechanisms to pause, resume, and clear pending operations. The tool covers broader traffic management capabilities including operation timeouts and concurrency

Uploader is a client-side library designed to manage asynchronous file transfers within web applications. It provides a comprehensive suite of tools for handling the entire upload lifecycle, including file selection, validation, transmission, and monitoring. The library distinguishes itself through its integration of drag-and-drop interfaces and structured queue management. It allows developers to organize multiple files into queues for sequential or parallel processing while maintaining programmatic control to start, pause, cancel, or reset individual transfer sessions. Beyond core transfer

OpenDroneMap (ODM) is an open-source aerial drone photogrammetry pipeline that converts 2D images into georeferenced 3D models, orthophotos, point clouds, and digital elevation maps. At its core, the OpenDroneMap Processing Engine orchestrates a complete Structure-from-Motion workflow, from feature extraction through dense reconstruction and tiled output generation, purpose-built for transforming drone-captured imagery into geospatial data products. The toolkit distinguishes itself through GPU-accelerated SIFT feature extraction using CUDA-capable NVIDIA graphics cards, roughly doubling proce
