pytimeago is a small Python library that transforms the numerical difference between timestamps into human-readable strings like "3h ago" or "5 months ago". Such functionality is often present in email, issue tracking and other applications that display a number of items to the user. It is practical to briefly describe the age of a certain item.
PyKCS11 is a PKCS#11 wrapper for Python. It lets you access almost all PKCS#11 functions and data types using any PKCS#11 library, such as the various modules supplied by smartcard vendors. It comes with two interfaces: a low level and very thin interface over the original PKCS#11 API, generated using the SWIG compiler (designed for library tests), and a high level interface that offers simpler access (with few limits) to the PKCS#11 APIs.
SpoonRPC is a library providing a distributed message passing system in Python. It attempts to be as simple to use as possible with little boilerplate code. It provides safe, efficient object serialization (not using pickle) and message routing. RPC is not (currently) implemented, despite the name.
arrayfrombuffer allows a programmer to use Numerical Python arrays whose contents are stored in buffer objects, including memory-mapped files. Loading an array from a file is easy, requiring only a module import and a single function call. Loading the array is quick because it doesn't require any copying from one part of memory to another. Arrays created with arrayfrombuffer are also highly memory-efficient, since only the array data that you are currently using gets loaded into memory. When an array is modified, only the modified parts get written back out to disk. These arrays can also be bigger than physical memory.
CalCore is an advanced, flexible calendaring component for Python. It allows the Python developer to write advanced calendaring applications either using their own event storage or integrating with external calendar servers. It features support for private calendars, shared calendars, resource booking, integration with iCalendar clients (Apple iCal, Mozilla Sunbird, KOrganizer) using the iCalendar protocol, invitation workflow, meeting support, including helper functions to look for free time, and recurring event support. It is being used as the core of Nuxeo's CalZope and CPSSharedCalendar products.
