Himerge is a GUI for emerge (Gentoo's Portage system) written in Haskell using gtk2hs. The main idea is to simplify browsing the entire portage tree, and allow running the most basic and common options from the emerge command. It also offers several handy tools, like global and local use flags browsers, inspired by UFED (the Gentoo Linux USE flags editor). It also uses eix (a small utility for searching ebuilds with indexing for fast results) as a back-end command to show package information in HTML/CSS format, so you can access a package's Web site for a quick glance.
VoiceBuntu (formerly Ubunterisk) is an Ubuntu-based live CD that uses Asterisk and VoiceOne to provide VoIP service without any system installation process. VoiceOne is a Web-based GUI for the Asterisk PBX. Ubunterisk can be used as a phone client as well as a PBX server. Ubunterisk can be administered either remotely or by accessing its local GUI. A capser-rw filesystem is used to store the system's data persistently.
Haiku (formerly known as OpenBeOS) is an operating system designed from the ground up for desktop computing. Inspired by the BeOS, it aims to provide users of all levels with a personal computing experience that is simple yet powerful, and free of any unnecessary complexities. It aims for source and binary compatibility with BeOS R5.
EasyOS is a GNU/Linux distribution focused on ease of use. It allows the user to perfom all the common tasks requiring a computer (Web browsing, text and image editing, etc.) in a intuitive way. Common applications such as Iceweasel, Abiword, Gnumeric, Gqview, Gimp, and MPlayer are integrated with ease of use in mind. EasyOS has been made to run on top of the OpenGate, a small computer developed by Neuf Cegetel, but it can be used on other x86 computers.
CD Linux Server is an embedded Linux system on a bootable live CD. It can be used to set up mail, Web, file, FTP, proxy, DHCP, DNS, MySQL, LDAP, and other services very quickly. The mail server includes antivirus, antispam, and mail recorder features. It can be used for free for up to 10 accounts, while the advanced version is licensed for an unlimited number of users. There is not any restriction against the time.
