Inside The Search For Jim Gray 115

An anonymous reader writes "InformationWeek adds some interesting new details to the story of unprecedented grass-roots search for Jim Gray, the Turing Award-winning database guru who helped set up Microsoft Research's San Francisco lab. Gray disappeared Jan. 26 after sailing out of San Francisco Bay to scatter his mother's ashes at the Farallon Islands, 27 miles offshore. Once the Coast Guard had given up its massive search, Gray's friends rallied the tech community — including people like Google co-founder Sergey Brin — into action. 12,000 volunteers spent 3 days examining 1.6 million hi-res images of ocean gathered by a NASA pilot who flew a U2 low over the area where Gray was thought to have disappeared. But it was all for naught. As Sendmail creator Eric Allman notes, Gray was expert at 'stripping away mystery by making things simple. It's an irony to me that he should end in a mystery.'"

      The camera array on NASA's ER2 is a tad more sophisticated than simply a DSLR or two. The relatively limited and older IRIS system covers a strip approximately 40 nautical miles wide: exactly what kind of setup could accomplish this on a turboprop? I am not saying it could not be done, but it would take more than a few days of work. The possible selection of cameras on the ER-2 is listed in the first link, the National Imagery Interpretability Rating Scales for civilian and military usage are 2nd and 3rd:

    I remember a freighter that came into Charleston harbor with a SAIL snarled in the anchor. The crew never heard or felt a thing, but the sailboat was never found. Their best guess was that the collision happened off the coast of Spain.

    If Gray's boat was run over by an outgoing freighter, he would have had little time to escape. The sailboat would have been sucked under the freighter and may or may not have come to the surface after the freighter's hull and propellers got through chewing on it.

      If he was in any way an experience Yacht master then there is no way that would happen. The only way you're ever going to get that type of collision is if the skipper in charge of the yacht is seriously inexperienced or there is zero visibility. Given that he was heading out to scatter his mother's ashes I doubt it was bad vis, that's the sort of trip you want to do in perfect conditions as you want it be a memorable experience.

      First rule of the sea, it is your responsibility to avoid a collision, regardless if the other vessel should give way to you.

        You are so wrong!

        I nearly got nailed by a tanker leaving Charlestown harbor at about 2:00 am.

        The tanker came out of Charlestown roads and immediately altered course straight in my direction.

        I had no engine and was totally reliant on sail, so my ability to get out of his way was restricted. I used flashlamps focussed on the bridge of the tanker, but nothing changed.

        In the end I had to use a distress flare, and the tanker missed me by about 20 feet.

        What many people don't realize is that modern ships are comouter driven, thereby only requiring one person on watch when under voyage. That person could have been taking a leak, studying a chart, whatever.

        When a tanker bears down on you at 15 knots, you don't have much time to react, and if you panic, what you DO do could be considered as counter productive, to say the least!

      When I first got my sea kayak I used to paddle around the harbour area taking a close look at the docked freighters. Until one day I noticed a ship being prepped to leave. One check they do is to drop the anchor. Makes sense, just don't be underneath when it happens because they don't winch it down. They drop it.

      So, how many times has this "experiment" been replicated?

      How is the problem defined and explained for the non-specialist? In a random throw of the darts, I can usually hit the bull's eye. If you make the target big enough and let me move up real close.

      • I haven't read the book, but this is from its wiki page [wikipedia.org]:

        The opening anecdote relates Francis Galton's surprise that the crowd at a county fair accurately guessed the butchered or the "slaughtered and dressed" weight of an ox when their individual guesses were averaged (the average was closer to the ox's true butchered weight than the estimates of most crowd members, and also closer than any of the separate estimates made by cattle experts).

        So it's not really "luck," as was suggested by the poster above you.

        • Oh, I wasn't suggesting Wisdom of the Crowds generally is based on luck, just that locating a ship on sea with that method is... well, idiotic.
          • Sure, this method of thinking is total crock and would never actually find anyone as readily and easily as traditional search and rescue methods. Oh? Traditional methods haven't worked? Oh. RTFA, RTFB, then render your opinion. I look forward to hearing your input. :)

              • All sorts of things were "BS" until they were proven otherwise. Most things are unbelievable because we lack the knowledge/experience to understand how something could be possible. All I asked was whether anyone participating in this search had applied such knowledge.

                  Not at all. The actual consideration would be more akin to "Every minute that slips by reduces the possibility of finding something. What's the next most reasonable method to use?". I don't believe that the WoC examples I've heard of translate well to this situation, as they all were based on people's guesses of things they all had observed.

      Remember the search for the Kim family, lost on a snowy mountain pass in Oregon?

      At the time, people wrote about potential ways to make searching distributed [4brad.com]: "traditional aerial photography is far better, because it's higher resolution, higher contrast, can be done under clouds, can be done at other than a directly overhead angle, is generally cheaper and on top of all this can possibly be done from existing searchplanes." And if the lost person has a cell phone, then the plane can also have "a small mini-cell base station (for all cell technologies) that could be mounted in a regular airplane and flown over the area." Traditional aerial searches are limited to only a couple of pairs of eyes, but continuous hi-res photos can lead to thousands of viewers. Of course, there was the question of what to do with gigabytes of photos- how to automate distribution.

      The Jim Gray search team found a way to distribute aerial photo searches. Using Mechanical Turk was a good idea, because the infrastructure was already there.

      Now, for the next lost family, or lost child, it'll be much faster to get photos up and examined.

      They're helping physical search enter the 21st century, not because he or his friends were money rich, but because his and his colleagues were data rich. i.e. if you look up petabyte science, Jim Gray's name shows up a bunch. If there was any quid pro quo it wasn't because the searchers were giving agencies money, it was because they gave new methods.
