    Dummy-Robot

    Dummy-Robot

    My super mini robotic arm robot project

    Dummy-Robot is an open source robotics project by Peng Zhihui that showcases the design and implementation of a compact robotic arm . The repository contains full hardware design files, firmware, control software, and 3D models. It includes components such as a gripper, LED light ring PCB, wireless spatial positioning controller, and a portable case. The project demonstrates advanced engineering with stepper motor drivers, custom controllers, and debugging tools. While the original version is CNC-machined, a simplified 3D-printable "youth edition" is planned to lower costs. This project serves as both an educational resource and a demonstration of innovative DIY robotics.

    FDUPES

    FDUPES

    FDUPES is a program for identifying or deleting duplicate files

    FDUPES is a lightweight command-line utility that helps users find and optionally delete duplicate files within specified directories by comparing file contents, which can be extremely useful for cleaning up storage clutter or organizing large collections of files. It works by scanning directories and subdirectories, identifying sets of files with identical content through size and hash comparisons, and then listing them together so users can examine duplicates. Once duplicates are identified, the tool offers interactive deletion options where users can choose which copy to keep and which to remove, or apply flags to automate deletion while preserving a single instance. Because it operates directly on file content rather than just filenames, fdupes can accurately detect true copies and guide cleaning operations in data cleanup or migration tasks. It’s a simple, efficient, and widely used utility on Unix-like systems, appreciated by administrators, developers, and power users.

    Kaldi

    kaldi-asr/kaldi is the official location of the Kaldi project

    Kaldi is an open source toolkit for speech recognition research. It provides a powerful framework for building state-of-the-art automatic speech recognition (ASR) systems, with support for deep neural networks, Gaussian mixture models, hidden Markov models, and other advanced techniques. The toolkit is widely used in both academia and industry due to its flexibility, extensibility, and strong community support. Kaldi is designed for researchers who need a highly customizable environment to experiment with new algorithms, as well as for practitioners who want robust, production-ready ASR pipelines. It includes extensive tools for data preparation, feature extraction, acoustic and language modeling, decoding, and evaluation. With its modular design, Kaldi allows users to adapt the system to a wide range of languages and domains. As one of the most influential projects in speech recognition, it has become a foundation for much of the modern work in ASR.
