NaSch.py is an implementation of Nagel-Schreckenberg vehicular traffic automaton. It uses Cage software by Erik Max Francis and the Python Imaging Library. It adds some new classes (a map, three rules classes, an automaton and an Image player) along with sample data to simulate vehicular traffic in a circular road.
Skyperious is a Skype database viewer and merger. It can open local Skype SQLite databases and look at their contents, search across all messages and contacts, browse, filter, and export chat histories, see chat statistics, import contacts from a CSV file to your Skype contacts, view any database table and export its data, change, add, or delete data in any table, and execute direct SQL queries. It can also compare two Skype databases, show the differences in chats and contacts, and copy any spotted differences from one database to another. Skype uses local database files to keep its chat history, and older messages tend to get lost as computers get upgraded or changed.
