W3C Semantic Web 

W3C Semantic Web looks like it may be the biggest, most impressive, and best designed web site on the semantic web I have seen to date. Its run by the University of Maryland, which is not suprising given their advanced Computer Science department. Jim Hendler is involved.

On-line Everything 

W3 Data is a company that provides "Products to help Businesses Find and Identify People and Businesses with Web, Batch and API Tools". It looks like you can buy an API for accessing directory data.

Mobile Computing 

Sprint PCS Application Developers Program would be a good place to start programming mobile devices.

Python Programming 

I have installed Python 2.3 finally. I've also added a powerful IDE under development named Boa Constructor for building GUIs out of wxPython, which is a blending of wxWindows and Python. This works together with PyOpenGL -- The Python OpenGL Binding a source for an OpenGL interface. In order to use PostgreSQL, I've loaded the win-psycopg PostgreSQL driver for Python. This package requires eGenix.com mx Extensions for Python. For doing Web services, I installed Python Web Services. But I had to add "import base64" to Client.py to make it work. For accessing the Google Web services API, I have installed PyGoogle, a package that wraps up access to Google through a high level client. For XML and RDF processing I have installed 4suite, from Forethought, Inc.

Web Programming 

W3C QA - The W3C Matrix is an interesting analysis of W3C specifications. It shows which of the specifications has a test suite, a conformance section, etc. Also interesting is that it is maintained in RDF. However, the RDF is not evident in the page. I wonder how I can find out how the RDF was used.
