binclock is a fullscreen console "binary" clock. Binary clocks show the time using blinking LEDs to represent 0s and 1s. The time is cut into decimal digits, each represented by a column of four LEDs ("bits"). This clock is mainly for amusement, but it can be used to train humans to "read" binary numbers pretty fast.
Plotter is a GTK+ mathematical graph plotting application. It is written entirely in Python using the PyGtk bindings. Features of Plotter include plotting of cartesian, parametric, and polar equations. An unlimited number of plots can be displayed in individual colours. Plotter supports graph zooming and panning, and loading and saving of sets of graphs. New functions can easily be added from within the program.
OpenEV is a library and reference application for viewing and analysing raster and vector geospatial data. OpenEV capabilities include the following: handling of raster and vector data, support for 2D and 3D display, graceful handling of very large (gigabyte) raster datasets, support for multi-channel raster datasets, understanding and interpreting of georeferencing information, pan/zoom/rotate at interactive frame rates (using OpenGL), and a powerful image analysis tool (using Numerical Python).
MapIt! is a simple Web-mapping application implemented in Python that lets you navigate raster maps through your Web browser. It lets you zoom in and out, and select objects and object classes that are highlighted on the map. MapIt! can be integrated with an existing Web server in several ways: as a CGI script, Fast-CGI, or in Apache with mod_python. It can also serve GIS results over the Web.
adlook (Address Lookup tool) is a multi-threaded host name and technical contact lookup tool. It accepts a list of IP addresses from the command line, from a data file, or from stdin, and outputs the hostname and technical contact for each address. Although it is written in Python, for the time being it runs only on UNIX systems. Python must have been compiled with threads enabled to run adlook.
Berkeley DB is a programmatic toolkit that provides high-performance built-in database support for desktop and server applications. The Berkeley DB access methods include B+tree, Extended Linear Hashing, Fixed and Variable-length records, and Queues. Berkeley DB provides full transactional support, database recovery, online backups, multi- threaded and multi-process access, etc. The Python wrappers allow you to store Python string objects of any length, keyed either by strings or integers depending on the database access method. With the use of another module in the package standard shelve-like functionality is provided allowing you to store any picklable Python object!
