A list of useful software (of mixted types):

• Lemur Toolkit for Language Modeling and Information Retrieval
• SNoW Learning Architecture
• WTL, Windows Template Library (lightweight windowing framework)
• boost::asio (C++ library for asychronous I/O, can be used to write networking programs)
• TidyLib (shallow HTML parser)
• GSL, GNU Scientific Library
• WordNet
• CherryPy (Python CGI package)
• GATE, a General Architecture for Text Engineering
• SQLite (lightweight database engine which can be embeded in applications)
• Berkeley DB (high-performance embedded database)
• Genshi (Python templating language)
• jQuery (Javascript library)
• FCKeditor (Javascript-based WYSISWYG editor)

Some tools written by me:

• Search logger (browser plug-in to log your web search history)
  
  • IE version (.msi)
  • Firefox version (.xpi)
  See here for usage.
• C++ wrapper for WordNet's C API (only supports HYPERPTR currently; easily finds the most frequent synset by tagged count)
• XSLT-based wrapper to convert Google's search result page to Yahoo's XML format (example). 4Suite and µTidylib are required. Cache URL and size are not implemented. You may have to change the xsl file to reflect the newest Google HTML...
