Famflows is a program which tracks "flows" of energy and materials inside a household. It has an alternative approach from double entry accounting systems. In those systems (like gnucash or jgnash), the transactions are balanced in numeric value. In famflows, instead, the transactions are balanced in the conversion, but not in the numeric value.
Yessh is a bash program that uses the SSH client. It provides fast connections to Linux/Unix hosts. Just type the name you have chosen for a host, and yessh will connect you via SSH. You don't need to remember the IP address, hostname, login, or password; just one arbitrary name. Accounts with passwords are kept in a secure file where passwords are encrypted using OpenSSL with 128-bit AES. You can use the autoconnect function to connect to your server with 5 keypresses.
jiggyMPD is a Web-based client for the Music Player Daemon and a companion tray icon. It is in relatively early development, but usable now. jiggyMPD extends the MPD data to add features MPD clients typically lack, such as ratings, date added, and last played date. This allows for some unique features. The jiggy data can be queried for smart playlist-type functionality. For example, "added <= 30, rating = 0, playcount <= 2, lastplayed > 1" will tell the client to find all songs added to your collection within 30 days, not yet rated, played 2 or less times, and not played today. It also fetches album art and lyrics.
