MusicBrainz Picard is a music tagging application, supporting multiple formats, looking up tracks through metadata and audio fingerprints.

LSP (Linux Studio Plugins) is a collection of audio plugins available as LADSPA/LV2 plugins and as standalone JACK applications.

Pure Data (aka Pd) is a visual programming language. Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically, without writing lines of code. Pd is used to process and generate sound, video, 2D/3D graphics, and interface sensors, input devices, and MIDI. Pd can easily work over local and remote networks to integrate wearable technology, motor systems, lighting rigs, and other equipment. Pd is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.

musl is a simple and lightweight C standard library. It strives to be correct in the sense of standards-conformance and safety.

Myrddin is a programming language. It features strong type checking, generics, type inference, closures, and traits. It aims for C like low level control. This combination makes Myrddin suitable for anything ranging from desktop applications, to embedded systems and potentially even kernel development.

Ncdu is a disk usage analyzer with an ncurses interface, aimed to be run on a remote server where you don't have an entire graphical setup, but have to do with a simple SSH connection. ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.

Dialog is a script-interpreter and a library which provides a set of curses widgets, such as dialog boxes.

Curses is the interface between Perl and the curses library of your system.

GNU Ncurses is a library which provides capabilities to write text to a terminal in a terminal-independent manner. It supports pads and color as well as multiple highlights and forms characters. It is typically used to implement user interfaces for command-line applications. The accompanying ncursesw library provides wide character support.

Curses Development Kit (CDK) is a C library of widgets which allow a programmer to quickly create TUI applications. Widgets are objects whose appearance and behavior can be customized, e.g. a pulldown menu or a file-viewer.

STFL is a language for easily describing GUIs. STFL is also the name of this library which translates those descriptions into a curses-based widget set for text terminals.

STFL descriptions do not contain any concrete layouting information, such as x/y coordinates of widgets. Instead, container widgets such as vertical and horizontal boxes, as well as tables, are used to group widgets. The actual layouting work is done by the STFL library. This allows STFL GUIs to handle terminals of different sizes and terminal resize events transparently for the application programmer.

Netpbm is a toolkit for the manipulation of graphic images, including the conversion of images between a variety of different formats. There are over 300 separate tools in the package including converters for about 100 graphics formats.

GNU Nettle is a low-level cryptographic library. It is designed to fit in easily in almost any context. It can be easily included in cryptographic toolkits for object-oriented languages or in applications themselves.

fping is a ping-like program which uses ICMP echo requests to determine if a target host is responding.

fping differs from ping in that you can specify any number of targets on the command line, or specify a file containing the lists of targets to ping. Instead of sending to one target until it times out or replies, fping will send out a ping packet and move on to the next target in a round-robin fashion.

This package provides a multi-threaded TFTP server that implements all options, including all extensions, as specified in RFC 1350, RFC 2090, RFC 2347, RFC 2348, RFC 2349 and RFC7440. Atftpd also supports a multicast protocol known as mtftp, which was defined in the PXE specification.

The server is socket activated by default but supports being started from inetd as well as in daemon mode.

This module provides several IP address validation subroutines that both validate and untaint their input. This includes both basic validation (is_ipv4() and is_ipv6()) and special cases like checking whether an address belongs to a specific network or whether an address is public or private (reserved).

IO::Socket::INET6 is an interface for AF_INET/AF_INET6 domain sockets in Perl.

uBridge is a simple program to create user-land bridges between various technologies. Currently, bridging between UDP tunnels, Ethernet and TAP interfaces is supported. Packet capture is also supported.

UsrSCTP is a portable SCTP userland stack. SCTP is a message oriented, reliable transport protocol with direct support for multihoming that runs on top of IP or UDP, and supports both v4 and v6 versions.
