GNU Mailutils is a rich and powerful protocol-independent mail framework. It contains a series of useful mail libraries, clients, and servers. These are the primary mail utilities for the GNU system. The central library is capable of handling electronic mail in various mailbox formats and protocols, both local and remote. Specifically, this project contains a POP3 server, an IMAP4 server, and a Sieve mail filter. It also provides a POSIX "mailx" client and a collection of other handy tools.
Meep is a free finite-difference time-domain (FDTD) simulation software package to model electromagnetic systems. It supports distributed-memory parallel simulations, nonlinear, anisotropic, and dispersive media, PML absorbing boundaries, and 1D/2D/3D and cylindrical problems. It is completely scriptable from either C++ or a Scheme (GNU Guile) interface.
MeeGo is a Linux-based mobile and embedded operating system. It brings together the Moblin project, headed up by Intel, and Maemo, by Nokia, into a single open source activity. MeeGo currently targets platforms such as netbooks and entry-level desktops, handheld computing and communications devices, in-vehicle infotainment devices, connected TVs, and media phones. All of these platforms have common user requirements in communications, application, and Internet services in a portable or small form factor. The MeeGo project will continue to expand platform support as new features are incorporated and new form factors emerge in the market.
