Multicast filtering on UW wireless networks?

Sitting with an idle laptop on a UW wireless network here at the Evans School, I typically see a constant 40-50kb/sec of traffic flowing into my machine.  At first I thought it was somebody attempting to hack or DDOS my laptop, but digging into the network packets with LittleSnitch showed me that all of this traffic was due to mDNS (Bonjour) broadcast traffic from other Apple machines on the network.

This seems like a huge waste of bandwidth and battery life to allow these network broadcasts.  Apparently other university IT administrators agree; Princeton University filters mDNS traffic from its wireless networks.  It would be nice to see UWIT do the same.

WSDOT traffic data: missing in action

With the recent start of tolling on SR-520 here in Seattle, the public’s attention is suddenly on traffic volumes on 520 and I-90.  So, this morning, I went over to the WSDOT website to see if I could find a simple listing of traffic volumes for the past few weeks.  Nothing, just a few random numbers sprinkled in their press releases.

Obviously, WSDOT is collecting this data.  It’s ridiculous that it’s not being published in formats that would make it easy to read and analyze.  What a huge open government data fail.
