GRASS (the Geographic Resources Analysis Support System) is a software raster- and vector-based GIS (Geographic Information System), image processing system, graphics production system, and spatial modeling system. It contains many modules for raster data manipulation, vector data manipulation, rendering images on the monitor or paper, multispectral image geocoding and processing, point data management and general data management. It also has tools for interfacing with digitizers, scanners, and the PostgreSQL, DBF, and ODBC connected databases. GRASS operates on all common operating systems.
HappyDoc is a tool for extracting documentation from Python source code. It differs from other such applications by the fact that it uses the parse tree for a module to derive the information used in its output instead of importing the module directly. This allows the user to generate documentation for modules which need special context to be imported.
httpMonitor is a Python program which lets you monitor the HTTP traffic between a browser and a Web server. You configure your browser to use httpMonitor as its proxy to ensure that all HTTP traffic between browser and server goes via httpMonitor. In a XML-configuration file you can specify a Python-function as processor for the HTTP-messages you are interested in (requests or responses, which match certain criteria). You may have as many processors as you want, without modifying the actual program. The only thing you need to do is configure the httpMonitor and write your processors.
ID3.py is an object-oriented Python module for manipulating the so-called ID3 informational tags on MP3 files, which include such data as artist, track title, genre, et cetera. ID3.py is extremely easy to use, and is intended for folks who are developing MP3 encoder wrapper programs or browsers in Python.
INN (InterNetNews) is an extremely flexible and configurable Usenet / netnews news server. It supports accepting articles via either NNTP connections or via UUCP, as well as serving out articles to reading clients via NNTP. It supports multiple different ways of sending outgoing articles to other hosts, as well as multiple different storage mechanisms for articles and article overview information via internal APIs. Compared to other news servers, INN is more complicated with a steeper learning curve, but is extremely flexible and configurable, comes with a large suite of supporting programs, and supports embedded filters in either Perl or Python.
Jack is a console based cd-ripper. It supports cdparanoia and cdda2wav (amongst others) for extraction and various MP3 and OGG/Vorbis encoders; you can even rip from a cdrdao-generated CD image. Emphasis is on failure-safeness and ease of use. Jack can encode multiple tracks at once, good on SMP systems. It can resume its work if interrupted and keeps an eye on available HD space. Freedb query is also supported, any time you like, even after encoding. Jack can try to query freedb for MP3s of which you do not know the CD anymore, provided you have a complete rip and know the track sequence.
