SSID-based SMTP server changer for Evolution is a simple script that uses gconf and NetworkManager (via D-Bus) to check which wireless network (SSID) you are currently connected to, and updates Evolution's accounts list (in gconf) to point to the correct SMTP server for that network. It is useful for when roaming between wireless networks that are connected to different ISPs.
The GNOME NetworkManager is a set of co-operative tools that make networking simple and straightforward. Whether wireless or wired, NetworkManager allows you to quickly move from one network to another: once a network has been configured and joined once, it can be detected and re-joined automatically at a later date. It was designed to auto-detect as much information as possible, seamlessly switches connections when necessary, and provides immediate feedback of the network state to users and applications.
dvtm brings the concept of tiling window management, popularized by X11-window managers like dwm, to the console. As a console window manager, it tries to make it easy to work with multiple console based programs like vim, mutt, cmus, or irssi. dvtm is intended to be used where X11 isn't available or over SSH. In conjunction with dtach, it can be seen as a lightweight alternative to GNU screen.
vlock is a program to lock one or more sessions on the Linux console. This is especially useful for Linux machines which have multiple users with access to the console. One user may lock his or her session(s) while still allowing other users to use the system on other virtual consoles. If desired, the entire console may be locked and virtual console switching disabled.
RSIBreak can be used to remind you to take a break now and then. It will show you a random picture from a collection you can configure yourself for a configurable duration at a configurable interval. You can use these breaks to do some stretch exercises, for example, or as a reminder to walk away from the computer for a while. RSIBreak will sit in your system tray, and when it is time for a break, it will show you the picture full screen. All timings can be set by clicking with the right mouse button on the icon in the system tray.
