Doing my part

I thought I’d do what little I could to help find Jim Gray by looking through some satellite pictures for Tenacious, Jim’s boat.

Dang, that’s not easy. Here’s a typical image that I was presented;

I did a dozen or so of them, and only a couple were a clear “No” (no ship or ship-debris-like object present). Two or three more were so noisy as to make the job impossible, so I “returned” them. The others involved more time than you’d expect, and a lot of squinting.

A technique that I found useful was to tilt my laptop display backwards which seemed to perform a low-pass filter of sorts, reducing noise and making it easier to identify objects. Maybe that would work for you too. My display is TFT.

It’s a tough job, but I’m happy to help.

Update; the images are a lot clearer today. I’m zipping through them.

The Web as an Exercise in Generalization

A message I sent to www-ws-arch this past summer seems to be making the rounds again. I don’t think I ever mentioned it in my weblog, so here ya go. Looks like it was mentioned on xml-dev, so perhaps that’s why. Er, and I forgot that I mentioned it in my “Playing Checkers with a Chess Set” blog too. Duh.

BTW, 10 kudos to whomever finds the “flaw” in the argument I made in that message. It’s not a fatal flaw, of course, but it does hilight the late binding issue, which I didn’t introduce in it (for fear of losing the simplicity of the point I was trying to make).

Update; the flaw is that when you get to the get/GET part, the message no longer means “get stock quote”, it just means “get a representation of what’s identified by this URI”. You find out if it’s a stock quote after you invoke GET. That’s late binding.
