Challenger myth vs. reality Sat, 28 Jan 2006 

As predicted by James Oberg in his fine article Seven myths about the Challenger shuttle disaster, the New York Times continues to propagate the myths in their homepage blurb at right—though they only had room to include two of them.

As Mr. Oberg says:

The flight, and the lost crewmembers, deserve proper recognition and authentic commemoration. Historians, reporters, and every citizen need to take the time this week to remember what really happened, and especially to make sure their memories are as close as humanly possible to what really did happen.

Retroactive Antarctica posts Fri, 27 Jan 2006 

Turns out we didn’t write any trip reports from Antarctica because we were just too exhausted! Also, email from the ship was about $3 per kilobyte. However, my intention is to write retroactive diary entries based on our pictures and notes. So keep an eye on early January…

Update, 4 Mar 2007: OK, so we’re not making lots of progress on this. :)

Batch-editing JPEG headers Fri, 27 Jan 2006 

I am going through the >3000 pictures we took in Antarctica, and noticed that some of them were way out of order. It turns out that one of the cameras’ clocks was set 12 hours off. Then I realized the other camera was set to Pacific time anyway, so really it was five hours off.

A few minutes of searching around later, I found jhead, a command-line JPEG header tool with a very convenient function:

jhead -ta+5:00 *.jpg

This adds five hours to the Date Taken of all the JPG files in a directory. Spiffy. A shout out to Matthias Wandel for making this free tool available. His pipe organ looks pretty neat too! There’s something about computer folks and pipe organs…
