    usbmuxd

    usbmuxd

    A socket daemon to multiplex connections from and to iOS devices

    A socket daemon to multiplex connections from and to iOS devices. usbmuxd stands for "USB multiplexing daemon". This daemon is in charge of multiplexing connections over USB to an iOS device. The daemon is automatically started by udev or systemd depending on what you have configured upon hotplug of an iOS device and exits if the last device was unplugged. When usbmuxd is running it provides a socket interface at /var/run/usbmuxd that is designed to be compatible with the socket interface that is provided on macOS. You should also create an usbmux user that has access to USB devices on your system. Alternatively, just pass a different username using the -U argument. usbmuxd is not used for tethering data transfers which uses a dedicated USB interface to act as a virtual network device. The higher-level layers, especially if you want to write an application to interact with the device, are handled by libimobiledevice.

    Darknet

    Darknet

    Convolutional Neural Networks

    Darknet is an open source neural network framework written in C and CUDA, developed by Joseph Redmon. It is best known as the original implementation of the YOLO (You Only Look Once) real-time object detection system. Darknet is lightweight, fast, and easy to compile, making it suitable for research and production use. The repository provides pre-trained models, configuration files, and tools for training custom object detection models. With GPU acceleration via CUDA and OpenCV integration, it achieves high performance in image recognition tasks. Its simplicity, combined with powerful capabilities, has made Darknet one of the most influential projects in the computer vision community.

    ESP8266Audio

    ESP8266Audio

    Arduino library to play MOD, WAV, FLAC, MIDI, RTTTL, MP3

    Arduino library for parsing and decoding MOD, WAV, MP3, FLAC, MIDI, AAC, and RTTL files and playing them on an I2S DAC or even using a software-simulated delta-sigma DAC with dynamic 32x-128x oversampling. ESP8266 is fully supported and most mature, but ESP32 is also mostly there with built-in DAC as well as external ones. For real-time, autonomous speech synthesis, check out ESP8266SAM, a library that uses this one and a port of an ancient format-based synthesis program to allow your ESP8266 to talk with low memory and no network required. All this code is released under the GPL, and all of it is to be used at your own risk. If you find any bugs, please let me know via the GitHub issue tracker or drop me an email. The MOD and MP3 routines were taken from StellaPlayer and libMAD respectively. The software I2S delta-sigma 32x oversampling DAC was my own creation and sounds quite good if I do say so myself.

    libwdi

    libwdi

    Windows Driver Installer library for USB devices

    libwdi is a cross-platform open-source C library focused on simplifying the installation of device drivers for USB hardware that otherwise does not have automatic driver support, making it especially useful for developers building installers or system management tools. The library abstracts away many of the complexities of USB device enumeration and driver deployment on Windows systems, such as creating a list of devices, preparing appropriate driver files, and invoking the operating system’s driver installation mechanics, so your software doesn’t have to re-implement these low-level tasks. It provides a clean API that includes functions to detect driverless USB devices, prepare driver packages, install drivers programmatically, and handle logging and error codes reliably. Projects integrate this library into custom installers, automated provisioning scripts, or hardware management solutions where users need seamless driver setup without manual steps.

    LibVNCServer

    LibVNCServer

    LibVNCServer/LibVNCClient are cross-platform C libraries

    LibVNCServer, a library for easy implementation of a VNC server. VNC is a set of programs using the RFB (Remote Frame Buffer) protocol. They are designed to "export" a frame buffer via net: you set up a server and can connect to it via VNC viewers. If the server supports WebSockets (which LibVNCServer does), you can also connect using an in-browser VNC viewer like noVNC. LibVNCServer/LibVNCClient are cross-platform C libraries that allow you to easily implement VNC server or client functionality in your program.

    LibSecRm - Secure Removal Library

    LibSecRm - Secure Removal Library

    A library for secure deleting data on-the-fly

    LibSecRm (LIBrary for SECure ReMoval) is a set of replacements for these standard C functions which cause data removing from files. The data is first securely wiped on-the-fly, to protect the user's privacy, then the original functions are called. There is NO NEED to rebuild your software, because LibSecRm is a pre-loadable library, meaning you just need to RUN the software with LibSecRm loaded. LibSecRm is also a development library. The following wiping methods are supported: Gutmann-like, random, Schneier, DoD. See the project homepage https://libsecrm.sourceforge.io and the project Wiki in the menu above. To wipe data that was left on the drive by using "normal" delete operations, you can take a look at WipeFreeSpace (https://wipefreespace.sourceforge.io), which wipes the space used by files marked as deleted (and other things, too).

    D-List

    D-List

    An extensive list subsystem, written in C

    D-List is an extensive, production quality, and robust list management subsystem written in C that can be used as a shared library or compiled directly into your project. D-List provides access to 3 classes of lists, and allows extensive manipulation and customization of these lists. D-List lists can also be easily incorporated as primitives into larger treed, or nested data management systems. D-List implements a comprehensive set of linked list primitives that provides multiple forms of both sequential and random element access, bi-directional movement within a list, and an extensive set of list and element manipulation and reordering features. It also provides for an expansive set of user functions that can be added to lists and called automatically, to efficiently implement a broad range of services using the list primitives as underlying technology. It was written primarily for accuracy and speed, and provides extensive debugging support for easy code development.

    LibNetBlock is a library that on-the-fly (by preloading) prevents a program under its control to use the network, to help to keep the user's privacy, prevent data leakage and virus spreading. You can think of LibNetBlock as a simple layer-7 (L7) firewall that simply blocks the network access for the program it controls. There is NO NEED to rebuild your software, because LibNetBlock is a pre-loadable library, meaning you just need to RUN the software with LibNetBlock loaded. LibNetBlock is also a development library.
