K-Man writes "Jim Gray, Turing Award winner and developer of many fundamental database technologies, was reported missing at sea after a short solo sailing trip to the Farallon Islands off San Francisco. Gray is manager of Microsoft's eScience group. The Coast Guard is searching for his vessel over 4,000 square miles of ocean, and there have been no distress calls or signals of any kind. Gray is 63 and a sailor with 10 years' experience."

Inside The Search For Jim Gray 115 comments
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.'"

An example would be if you have an address book, listing about 50 people you know, with names and addresses (But no phone numbers)
You also have a phone book, with names and phone numbers of everyone in your city. Let's say 1 million people.
Let's say you've got an address ("12 Pear Tree"), and you want a phone number. To find this information you've got to use the address book to locate the name of the person living at that address, then look up that name in the phone book.
In SQL, you'd do that search like this: It's saying "Find every address entry where the address is "12 pear tree", and out of all the possible combinations of address book entry and phone book entry, just give me the ones where the names match."
That'll give you the result you want. However, it's that last bit of SQL that's easy to forget, the "phone_book.name=address_book.name" bit. Without it, you're doing a Cartesian join. The database says "Ahh, they must want every combination of these two tables".
So instead of getting one result, you'll get one million results. The address has to be "12 pear tree", but the database is free to match that up with EVERY entry in the phone book, and it will.
That's what the grandparent post was referring to. SQL just makes that mistake very easy to make, and you'll end up with a GIANT pile of results flying at you if you make it.

- It keeps operations that are conceptually seperate (joins and filtering the data set) syntactically seperate.
- A few other advantages, including: full outer joins are possible which had to be fudged with UNIONs before, and cartesian products cannot be created accidentally but have to be explicitly specified.

These signals are picked up by either the INMARSAT geostationary satellites, or also passing weather satellites. Without a GPS position, the weather satellites can locate the beacon to within about 50 miles. With an integrated GPS receiver, the position will be reported to about 2 miles or so. (The message format doesn't have the space to transmit full resolution).

Most of these are designed to float out of their holder in case of a sinking and are water activated. The lack of a signal for this size vessel is a good sign it's still afloat. Whether he is alive or onboard is to be seen. He could have had a medical emergency or fallen overboard which would not activate the beacon.

Do you show compassion for people you don't know? Or at least heard about? I have a hunch the reaction would be slightly different if, say, Hawking was gone missing or even dead.
People dying is no longer something that bothers us. That's not even a Slashdot phenomenon. We see and hear it all the times, in the news. People die. Deal. That's what we get told, and thus death (as long as it's not someone we care about) has become something to shrug off. When you get told that people dying in a war as innocent bystanders are brushed aside as collateral damage, you tend to get quite cold inside.
So I wouldn't really wonder how that comments come into existance. It's simply the normal flow of operation.

So what are we to do? Those who have a connection with the man (knew him, worked with him, admire his work, etc.) will have serious and informative comments to make. But for the rest who've never heard of him, there's just nothing to discuss -- the story's not about technology in any way, it's just about a human being who happens to be related to technology. And death is easiest thing in the world to come up with jokes about -- "I bet he died because [a common failure in whatever area of technology he is related to]...ha,ha". Yes, the Microsoft/bluescreen jokes are pretty lame, but the SQL/database ones get a chuckle out of me.

Possibly run down by a larger ship (Score:5, Informative)
He went out in a 40-foot C&C 121 yacht [c-cyachts.com]. That's a very nice boat, with a epoxy resin laminate hull, carbon fiber reinforcement and masts, Kevlar sails, and a 38HP engine. There hasn't been any weather lately bad enough to give a boat like that any serious trouble. If it ran aground it would probably survive the experience.
But between San Francisco and the Farralon Islands is a major shipping lane. One with fog. Container ships and oil tankers come through there. Sizable fishing boats have been run down and sunk without anyone on a large ship even noticing. There's a USGS Vessel Traffic Service [uscg.mil] station and established traffic lanes for large ships, but small boats aren't required to check in with traffic control.

Sailing in the SF Bay (Score:5, Interesting)
Just a couple bits of information for those not familiar with sailing in the SF bay. I used to own a small sailboat in the SF bay, a Cal-20. Just about the smallest (and slowest) real keel boat you can find. The SF Bay has some of the finest sailing in the world. Between April and October, the wind at the gate is a nice steady 7 to 10 knots all day long.
Most people think of California and picture the sunny beaches and warm water off LA. This doesn't exist north of Santa Cruz. California north of Santa Cruz has a rocky cliff shore. The water off SF is chilled by a current that comes down from Alaska. This time of year, it's probably 40 deg/F (4.5 deg/C), in the summer, it's not much warmer. The cold water kills people very fast. You fall in this time of year, and you have maybe 15 minutes before you're dead. They've lost experienced sailors to hypothermia inside the bay, where the water is slightly warmer, in the amount of time it takes the crew to pull down the sheets and do a man overboard 180. If he fell overboard without some kind of wetsuit or thermal protection, he's done. A 40 foot boat set up for solo would probably have some kind of steering autopilot, and would sail outside the initial search area on it's own in just a few hours.
The sea will try very hard to kill you. A fellow geek made the good life, and appears to have been settling in to enjoy his golden years. Most of us have similar dreams and aspirations. I don't know him, but I'm going to think good thoughts for him and his family, and hope for the best.

So it's probably calloused to be talking about the Darwin award, but this is something you simply have to expect when you go on these solo sailing expeditions. Sure, there's the allure of "one man against the sea," but the sea often wins (has a very long history of wins, in fact), and if you don't take the necessary precautions, well... when you want to take your life into your own hands like that, by definition everything that happens to you is your own fault.
Hidden Dangers for Small Boats (Score:4, Informative)
I have a friend in high places at the Port of Los Angeles, and though the shipping companies do NOT like to talk about it, the ship grounding on the U.K. coast just a week ago illustrated the problem. Some dozens or a hundred containers or so came off the ship when it listed, and then some FLOATED ashore.
The numbers I have heard is about 10,000 containers a year 'go missing' overboard as a result of all sorts of problems in bad weather usually. I don't remember whether that was the Pacific only or worldwide.
Lots of these containers floating right near the water surface with any waves at all, are virtually impossible to see from any distance.
If you hit one in a fiberglass or a thin-skinned metal boat boat, you can take on water and sink in a minute or two if it is bad.
Lots of small boats go missing every year with no explanation.
