Freeway data
I got an account with the site that distributes the sensor data from the loops in the freeways (pictured here). Here's the first hack, a boring map of the sensors with 10% of the speeds labeled. Code is in darcs.
This screenshot shows my map on the right; a comparable sigalert screenshot on the left.

I worked on maps.bigasterisk.com (which is probably still broken as you read this). My plan was to add estimated arrival times to the map, but without ever specifying my destination. There would just be arrival times all over the map (but maybe not behind me, where it's clear I'm not going). I was going to attempt SVG-over-gmaps for the time display.
Then I remembered I also wanted a lightweight live chat for concurrent viewers of my web page, so I wrote that. Then I installed it to maps.bigasterisk.com, and the live chat didn't work. I narrowed this down to a problem with apache, since the same server and client would work without apache in the middle. Debugging the issue started taking forever, so I'm now considering replacing my apache proxy server with something else.
I also heard some praise for google reader and konqueror and offered some praise for mochikit.

gps tracker
Today I wrote a thing with the python gps module (from gpsd), a nevow website with livepage, and google maps. Then I went out on the road with a gps receiver, laptop, and Treo 600 and broadcasted my position. You could watch me move at http://maps.bigasterisk.com
darcs get http://darcs.bigasterisk.com/maps
to get the code, or just look at:

for the good parts.
