This will be a quick update, because I suspect that I would be asleep long before I could even summarize our entire trip. We're in the 'Blanchard' or 'Terre Noir' neighborhood, perhaps a mile north of Cite Soleil - in Port au Prince. The clinic...

I write this from JFK airport in New York, having successfully gotten out of the house at 5am carrying four duffel bags containing just under 200lbs of (mostly) donated supplies. Our clothing and personal gear are in our carry on luggage. I remain overwhelmed by...

On Friday the 29th of January, I will be taking a week's leave of absence from my day to day responsibilities at Bioteam and traveling to Haiti with a medical relief team. I'll be going with a group called Family Health Ministries. We'll go overland...

In a previous post I described how and why one might set up a very simple ssh tunnel in order to access a web server or a remote desktop server on a machine with a restrictive firewall. This post goes one step deeper, showing...

A basic introduction to ssh tunnels: As a first puzzle, assume that a friendly administrator gave me an ssh account on her web server. However, her organization's security scheme only allows me to get to port 22. I can ssh in, but...
