MinimalModbus is an easy-to-use Python module for talking to instruments (slaves) from a computer (master) using the Modbus protocol. Example code includes drivers for Eurotherm and Omega process controllers. The only dependency is the pySerial module. This software supports the ‘Modbus RTU’ serial communication version of the protocol, and is intended for use on Linux, OS X, and Windows platforms. It has been tested with Python2.6, Python2.7, and Python3.2.
Xataface Email Module allows you to email to the results of any set found in a Xataface application. This allows you to easily convert your existing database of contacts into a mailing list. It supports HTML email, recipient opt-out, mailmerge macros, and more. The email is sent in the background via a cron script, so arbitrarily large email lists can be supported.
JTelIRC is an advanced IRC framework for Java. It is mainly intended for writing automated clients ("bots"), but may be used for normal clients as well. It provides an intuitive and well documented Java interface to IRC and makes it extremely easy to write advanced clients quickly.
FECpp is a C++ library implementing a fast forward error correction code, sometimes also called an erasure code. These codes are used to split input data into a set of n shares, with the property that if any subset of at least k shares survives, the original data can be recovered by the decoder. The number of share losses the code will tolerate can be parameterized during encoding, allowing the code to be adapted to to a variety of loss scenarios. FECpp is bit-for-bit compatible with several other FEC libraries.
