Former Gizmodo Editor in Chief, Joel Johnson is one of many from the Technology community trying ot help Hurricane Katrina victims in the United States.
Joel is at the Astrodome in Houston where they try to setup low-power FM radio for the refugees in the stadium. The blog posts indicate that they got approval to do it, but it all sounds like an very unorganized and bureaucratic situation there.
They group also succeeded to setup Wi-Fi to give the people access to the internet to find out about their families.
Joel posts on Gizmodo the progress. You can support the CUWireless group with equipment. Wired News also has a report about the efforts to bring back some infrastructure to the devastated region - lots more encounter of bureaucracy.
Boing Boing has also several reports from the Astrodome. It seems that most of the reporting available from the inside is from bloggers and not from the "official press".
Jacob Applebaum who is in the same group as Joel has published tons of photos on his Flickr stream.
