(Serial Ports on) Steroids enables users to execute remote C functions in a Python shell over a serial interface. It is useful for embedded system testing and industrial automation. It generates C code for the target and a Python script for the host automatically from a C header file.
AdlMIDI is a command line program that plays MIDI files using software OPL3 emulation (FM synthesis). It has a console UI. It features a built-in selection of 50 patch sets, most of which are General MIDI compatible, but some of which are customized for playing original background music soundtracks of select PC games.
aircrack-ng is a set of tools for auditing wireless networks. It's an enhanced/reborn version of aircrack. It consists of airodump (an 802.11 packet capture program), aireplay (an 802.11 packet injection program), aircrack (static WEP and WPA-PSK cracking), airdecap (decrypts WEP/WPA capture files), and some tools to handle capture files (merge, convert, etc.).
Autodl2 is a simple to manage and extensible file transfer system that can be configured simply using a configuration file. The system is designed to be lightweight and handle multiple file transfer protocols. Currently only SFTP is supported, though other systems can be added via a plugin system.
BACnet is an implementation of the BACnet (Building Automation and Control Networks) protocol specifically tailored for embedded systems. BACnet itself is a standard routable protocol designed to handle communications in automation in buildings, such as air conditioning systems and other HVAC equipment.
Backshift is a deduplicating (variable-sized, content-based blocks), compressing (xz or bz2) backup program. Full saves and incrementals are pretty indistinct other than the amount of data transmitted, somewhat like with "rsync --link-dest" but without the huge number of hardlinks. It also de-duplicates large file content at a granularity of about 2 megabytes on average; there tends to be a unique copy of each file with size less than around 2 megabytes on average.
