pftp allows you to send and receive files and directories recursively, send and receive standard input and ouput, filter your connection, set the net buffer size, set the bandwidth, send UDP datagrams unicasted, broadcasted, and multicasted (which is meant for AUDIO and VIDEO streaming), send data to another user and manage that data, perform a network test based on either UDP or TCP, and use optimized buffers for your Gigabit Ethernet links. pftp can start from command line, as a daemon, or by inetd. All features are supported for IPv4 and IPv6.
pyChing is a program that allows you to 'consult' the I Ching. The I Ching is an ancient Chinese book of wisdom, which, apart from being read as a book, has also traditionally been consulted as an oracle. pyChing allows you to perform an I Ching 'reading' using the coin oracle, and then look up a brief interpretation from the I Ching. pyChing is completely written in Python, a cross platform, object oriented, programming language, using the Tkinter interface to the Tk GUI toolkit.
Pysync has both a demonstration implementation of the rsync and related algorithms in pure Python, and a high speed librsync Python extension. The pure Python is not fast and is not optimized, however it does work and provides a simple implementation of the algorithm for reference and experimentation. It includes a combination of ideas taken from librsync, xdelta, and rsync. The librsync Python extension is less flexible and harder to understand, but is very fast.
QVocab is a program that should help you to learn the vocabulary of a foreign language. You add your words into a simple database file, the program asks you the words and you try to answer with the corresponding word of the other language. A known word will move up one level (there are five of them) and if you didn't know its meaning, it is moved to the first level again.
