    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.

    CAVA

    CAVA

    Cross-platform Audio Visualizer

    Turn your phone or tablet into a fantastic audio viewer. Easy to use and customize. Choose from several preset settings of incredible colors or create your own. CAVA is a bar spectrum audio viewer based on my own open source project with the same name. Take the audio from the device's microphone and visualize the amplitude of the different frequencies as bars on the screen. Each bar represents a certain bandwidth of low to high frequencies. The leftmost bar starts at 50 Hz and the rightmost bar ends at 10 kHz. Although the frequencies outside this spectrum are audible, they do not contribute much to the overall sound image. You can also adjust the number of bars.

    ESP8266 Deauther Version 2

    ESP8266 Deauther Version 2

    Affordable WiFi hacking platform for testing and learning

    Scan for WiFi devices, block selected connections, create dozens of networks and confuse WiFi scanners! Version 3 is in development. It is stable to use, but it is very different. It is command-line based, which allows it to offer not just more features, but make them more customizable. This software allows you to easily perform a variety of actions to test 802.11 wireless networks by using an inexpensive ESP8266 WiFi SoC (System On A Chip). The main feature, the deauthentication attack, is used to disconnect devices from their WiFi network. No one seems to care about this huge vulnerability in the official 802.11 WiFi standard, so I took action and enabled everyone who has less than 10 USD to spare to recreate this project. I hope it raises more attention on the issue. In 2009 the WiFi Alliance actually fixed the problem (see 802.11w), but only a few companies implemented it into their devices and software.

    WebP Codec

    WebP Codec

    Library to encode and decode images in WebP format

    libwebp is the reference codec library for Google’s WebP image format, providing both encoding and decoding along with command-line tools. It supplies cwebp to compress images into WebP and dwebp to decompress them back, making it easy to test quality/size trade-offs across presets and tuning parameters. The GitHub repository is a mirror; the canonical source of truth lives on Chromium’s git, and developer docs are hosted on WebP’s portal. The project underpins WebP support across browsers, imaging libraries, and many native apps thanks to its stable C API. Additional companion repos host test data and demos, including JavaScript builds and timing tests for various platforms. As a widely deployed codec, libwebp balances compression efficiency, speed, and integration simplicity across platforms.
