Playlist Warlock is a text-based frontend for mpg123 written in Perl. It is intended to provide users with the playlist browsing and song selection of a GUI MP3 player from any terminal. It provides a combination of Winamp/XMMS, vi/less, and Unix prompt-style commands for creating, editing, sorting, and navigating MP3 playlists. Using mpg123 as a backend, PLWarlock allows the user to easily browse playlists and play MP3s. It supports contiguous and random play, simple jump-to-song syntax, sorting by filename/path+filename, and all the other commands you've come to expect from a good MP3 player.
The GNOME Wireless Applet is a wireless link quality monitor panel applet for GNOME. It reads the link quality out of /proc/net/wireless and reports quality by altering color, like a mood ring. It also provides a management console (GUI) to change wireless extension settings, including encryption keys, power management, and operation mode.
LiMpOo is a multimedia player platform based on a Linux system using a Perl engine. It features playback of MP3 files (with playlists), CD audio (with CDDB lookup), and support for encoding, LCD, and IR. It uses MySQL for speed improvements. A PHP front-end helps to maintain all playlists.
