Both clever elephant and Map Hawk discuss the new New York Times webmapping tool called "Represent" which tracks people representing New Yorkers: "Using your address as a starting point, Represent figures out which political districts you live in and who represents you at different levels of government. It draws maps that show how where you live fits into the political geography of the city. And using information collected from around the Web, it presents a customized activity stream that tracks what the people who represent you are doing."
Amongst the interesting bits, the tool is based on open source geospatial software: PostGIS, GeoDjango, GEOS, GDAL and more.

The Slashdot Django 1.0 summary: "Finally, the stable version 1.0 of Django (one of the most popular free Python based frameworks) has been released.

GDAL/OGR 1.6.0 Released
[+]
Major news, the almost ubiquitous GDAL/OGR library 1.6.0 has been released. Here's the official site. I dare repeat, GDAL/OGR is used by most open source geospatial projects, but also by many proprietary ones, like Google Earth and ESRI products.
From the release notes, this is only the general highlights, because the list is very long: "General:
* RFC 20: Preliminary support for alternate axis orientations in SRS.
* On the fly access to data in .zip and .gz compressed files.
* RFC 22: Support for reading from, and warping with RPC (Rational Polynomial Coefficients) from various formats.
* Gaussian and Mode resampling added for overview generation.
* Added raster to vector (polygon) conversion utility.
* Added raster proximity utility.
* Added raster sieve filtering utility.
* Added -expand rgb/rgba ability to gdal_translate
* Added cutline / blend support to gdalwarp.
* Added -segmentize option to ogr2ogr to break long line segments.
* RFC 23: Preliminary support for character set transcoding (in OGR for now).
* RFC 21: OGR SQL supports type casting and field name aliasing"
