Thanks and goodbye to hn.org
[HammerNode](http://hn.org/), a free dynamic dns service by Gregory Keefe, is going down in mid-February after five years of operation. Thanks and goodbye. It was a great service when I needed it.
For reference of folks who need it, there's a [long list of other ddns services over at DMOZ](http://dmoz.org/Computers/Software/Internet/Servers/Address_Management/Dynamic_DNS_Services/).
