CNN has its list of Top 10 bizarre e-mailed stories of 2004. The number one story:
"Bear guzzles 36 beers, passes out at campground" (August 18)(Via Mark Dennis.)
Campground workers at the Baker Lake Resort on Washington State's Puget Sound were surprised to find a black bear passed out and surrounded by three dozen beer cans. The animal had swiped the suds from campers' coolers and seemed to take a liking to the local brew, Rainier Beer.
The bear was chased away only to return the next day, presumably looking for more beer. Wildlife agents captured the bear using honey, doughnuts and beer for bait.

Obnoxious shrink-wrap EULA's may have suffered a major legal defeat:
In January 2003, California resident Cathy Baker walked into her local CompUSA store to return copies of Windows XP and Norton AntiVirus she'd purchased there. When trying to install the programs, she had of course been confronted by all the obnoxious terms in the Windows and NAV End User License Agreements. Instead of clicking OK, she took them back to the store for a refund, as the EULAs said she was supposed to do if she refused to accept the terms.(Via MBWHA.)
At CompUSA, however, Baker was told the store's policy was that it could not give refunds for software once the customer has opened the package. Even though Baker had no way of seeing the EULAs until after she purchased the products, took them home, opened the package and tried to install the software on her computer, she was now told she could not get her money back even when she rejected the terms. (In a somewhat bizarre twist, after she protested enough, one CompUSA employee told her that they had "secret instructions" from Symantec to provide refunds in such circumstances.) So, like many others before her, Baker was confronted with the classic shrinkwrap license conundrum: She could only see the terms by opening the box, and opening the box meant she was stuck with it. But Baker did something most others before her had not - she went and got a lawyer...

Spam messages offering free high-tech consumer goodies: What happens if you respond. From the article:
The e-mail messages are tantalizing: "Join now and receive a free IBM laptop." "Your complimentary iPod with free shipping is waiting."
These offers and similar ones on the Internet promise gifts for buying products or services. Are they for real? At best, yes, but they can also be riddled with problems. Participants may have to spend a lot to qualify or may not get the reward if they fail to follow what can be complicated rules. Ultimately, they may end up with nothing more than a big increase in spam as their e-mail address and other information is passed along or sold.

"A Precious Case from Middle Earth": The latest issue of The British Medical Journal has a case report on Smeagol, aka "Gollum". Among their conclusions,
"He fulfils seven of the nine criteria for schizoid personality disorder (ICD F60.1), and, if we must label Gollum's problems, we believe that this is the most likely diagnosis... He is hypervigilant and does not seem to need much sleep. This, accompanied by his bulging eyes and weight loss, suggests hyperthyroidism."Of course, it could also be the effect of the One Ring, something not yet included in the current ICD-10 (International Classification of Diseases) codes.

(As a practicing radiologist, I thought the article was especially good in its discussion of the limitations of mammography and breast cancer screening, as well as the gap between the reality of mammography vs. popular perception. Gladwell did a good job integrating a number of complex ideas in medicine and image analysis.)

"Seeing is believing (in the free market)": Alex Tabarrok has some very interesting observations about health care economics.
Everywhere we look it seems that health care is more expensive: prescription drug prices are increasing, costs to visit the doctor are up, the price of health insurance is rising. But look closer, even closer, closer still. Don't see it yet? Perhaps you should have your eyes corrected at a Lasik vision center.
Laser eye surgery has the highest patient satisfaction ratings of any surgery, it has been performed more than 3 million times in the past decade, it is new, it is high-tech, it has gotten better over time and... laser eye surgery has fallen in price. In 1998 the average price of laser eye surgery was about $2200 per eye. Today the average price is $1350, that's a decline of 38 percent in nominal terms and slightly more than that after taking into account inflation.
Why the price decline in this market and not others? Could it have something to do with the fact that laser eye surgery is not covered by insurance, not covered by Medicaid or Medicare, and not heavily regulated? Laser eye surgery is one of the few health procedures sold in a free market with price advertising, competition and consumer driven purchases. I'm seeing things more clearly already.

Joke of the day:
A couple is golfing one day on a very, very exclusive golf course lined with million dollar houses. On the third tee the husband says, "Honey, be very careful when you drive the ball. Don't knock out any windows it'll cost us a fortune to fix."(Via Michael Duff.)
The wife tees up and promptly shanks it right through the window of the biggest house on the course. The husband cringes and says, "I told you to watch out for the houses! All right, let's go up there, apologize and see how much this is going to cost."
They walk up and knock, and a voice says, "Come in."
When they open the door, they see glass all over the floor and a broken bottle lying on its side in the foyer. A man on the couch says, "Are you the people that broke my window?"
"Uh, yeah," the husband says. "Sorry about that."
"No, actually I want to thank you. I'm a Genie that was trapped for a thousand years in that bottle. You've released me. I'm allowed to grant three wishes. I'll give you each one wish, and I'll keep the last one for myself."
"OK, great!" the husband says. "I want a million dollars a year for the rest of my life."
"No problem - it's the least I could do.
And you, what do you want?" the Genie says, looking at the wife.
"I want a house in every country of the world," she says.
"Consider it done."
"And what's your wish, Genie?" the husband asks.
"Well, since I've been trapped in that bottle, I haven't had sex with a woman in a thousand years.
My wish is to sleep with your wife."
The husband looks at the wife and says, "Well, we did get a lot of money and all those houses, honey. I guess it's OK with me if it's OK with you."
So the genie takes the wife upstairs and ravishes her for two hours.
Afterward, he rolls over, looks at the wife, and says, "How old is your husband anyway?"
"He's 35, why?", she asks.
"And he still believes in Genies?"

"Who Knows?": Excellent article on Wikipedia and how it works. One interesting tidbit:
To put Wikipedia's achievements in numerical context, at the same time it was celebrating the publishing of its one millionth entry (a Hebrew article on the Kazakhstan flag) in less than four years, the Oxford Dictionary of National Biography launched its latest edition. It had taken 12 years to complete, yet contained a comparatively tiddly 55,000 biographies. It also cost some £25m to create. Wikipedia has so far been bankrolled by Wales, but the total cost so far is still around £300,000.Just for reference, £1 UK = $1.85 US. (Via LinkMachineGo.)
The current Encyclopedia Britannica has 44m words of text. Wikipedia already has more than 250m words in it. Britannica's most recent edition has 65,000 entries in print and 75,000 entries online. Wikipedia's English site has some 360,000 entries and is growing every day.

The key point was that the restaurant menu described the 18% requirement for large parties as a "gratuity" (i.e., at the customer's discretion), not a "surcharge" (i.e. mandatory).

Neuroscientist Michael Weliky learned something interesting about mammalian neural activity when he had 12 ferrets watch The Matrix. As Weliky summarizes,
It's one thing to say a ferret's understanding of reality is being reproduced inside his brain, but there's nothing to say that our understanding of the world is accurate. In a way, our neural structure imposes a certain structure on the outside world, and all we know is that at least one other mammalian brain seems to impose the same structure. Either that or The Matrix freaked out the ferrets the way it did everyone else.(For the record, I disagree with the concept of consciousness "imposing a structure on the outside world", but I found the article entertaining nonetheless.)

(Actually, your brainwaves control a magnet under the table that moves the ball, but it *seems* as if you're controlling the ball directly.) By relaxing your mind, you can make the ball roll over to the opponent's goal. So to win, you have to "out chill" the other person. I was skeptical, until I actually sat down to play against my friend Nick Philip, an ambient DJ/artist who is in the business of chilling. He beat me every time.Now only $20,000 US.

Coke-vs-Pepsi neuromarketing: Functional MRI brain scans show that Coca Cola's advertising and branding has been far more succesful than Pepsi's in creating consistent preferences for their beverage.
The experimental design enabled the researchers to discover the specific brain regions activated when the subjects used only taste information versus when they also had brand identification. While the researchers found no influence of brand knowledge for Pepsi, they found a dramatic effect of the Coke label on behavioral preference. The brand knowledge of Coke both influenced their preference and activated brain areas including the "dorsolateral prefrontal cortex" and the hippocampus. Both of these areas are implicated in modifying behavior based on emotion and affect. In particular, wrote the researchers, their findings suggest "that the hippocampus may participate in recalling cultural information that biases preference judgments."I predict this is just the beginning of the neuromarketing cola wars.

Iterated Prisoner's Dilemma: For many years, the optimal strategy has been the Tit-For-Tat strategy, in which the computer player mirrored its opponents' moves. However, during the recent 20th Anniversary Competition, a new consistent winner emerged using a radically different approach known as the Southampton Strategy.
The last Washington Redskins home football game prior to a presidential election has correctly predicted the election winner going back to 1936. (The Redskins did not exist as a franchise prior to 1936.) This year, the critical game will be on October 31, against the Green Bay Packers. If the pattern holds true for 2004, then a Redskins victory = Bush, Packer victory = Kerry. (Of course, I think it's all a coincidence, since there are any number of possible "predictive" sports streaks, and sooner or later one is bound to match this pattern of 17 straight election results. But I still find it interesting nonetheless...)

Update on XP vulnerability: A couple of people have pointed out that this is not a new discovery. Apparently, using any other OS boot CT (with appropriate file system software) allows one to bypass the OS not used. Thanks to Bryce Wilcox and Stewart Vardaman for writing in. So the story might not be as big a deal as portrayed in the article.
XP passwords rendered useless: A major XP security hole has been found.
Windows XP, which has been marketed by Microsoft as "the most secure version ever," has been found to have a flaw so bone-headed that it renders passwords ineffective as a means of keeping people out of your PC.(Via Linkfilter.)
Reader Tony DeMartino alerted me to the problem, which all administrators of Windows XP machines should immediately take to heart:
Anyone with a Windows 2000 CD can boot up a Windows XP box and start the Windows 2000 Recovery Console, a troubleshooting program.
Windows XP then allows the visitor to operate as Administrator without a password, even if the Administrator account has a strong password.
The visitor can also operate in any of the other user accounts that may be present on the XP machine, even if those accounts have passwords.
Unbelievably, the visitor can copy files from the hard disk to a floppy disk or other removable media - something even an Administrator is normally prevented from doing when using the Recovery Console.
The Vickrey Auction: If you're selling a valuable item via sealed-bid auction, it might be to your advantage to use the Vickrey auction system, in which the item goes to the highest bidder, but he or she gets it for the price of the second-highest bid. Mathematician Francis Su explains why.

Global warming fears may be based on a systematic error in climate modelling. According to the article:
The Earth's temperature may have fluctuated more wildly during the past 2000 years than previously thought, according to a new study that challenges how researchers use tree rings and corals to give us a picture of the Earth's past.More information here.
If true, the study suggests that recent warming might not be as unique as was thought previously, and might partly be due to natural temperature cycles, rather than humans spewing carbon dioxide into the atmosphere.

"Ins and Outs of Teledildonics": Wired has a review of the Sinulator, a remote cybersex device that connects to the USB port of one's personal computer. As the article explains, "...a man can be thrusting in Cleveland while a woman is penetrated in Seattle, and the cybersex experience gets one step closer to the holodeck."
"Klingons for Kerry": A recent poll of the Klingon population of Portland, OR, showed that 75% of them supported John Kerry for president, whereas 25% supported Satan and 0% supported George Bush. One reason they cited was their belief that the current war in Iraq was based on deception and hence dishonorable. (Via Volokh Conspiracy/Hanah Metchis.)

Update on the "Home Computer" picture: The photograph is apparently a Photoshopped hoax. Reader Mike Jaeger pointed out,
That is the control panel from an old naval nuclear reactor. On the far right is the EPCP (electric plant control panel) where the electrical operator on watch ("EO") controls power flows and breaker positions (notice the schematic laid out with switches for breakers). In the middle section is where the reactor operator ("RO") sits. He shims the control rods up and down in the reactor core with the lever (the L shaped lever just in front of the horizontal bar) and on the left is the throttleman station (usually manned by electricians). The large wheel is used to open/close ahead steam valves to the propusion shaft, while the smaller wheel is used to open/close back steam (astern throttles). The two wheels would be used in conjunction with each other to get the shaft to stop from a forward rotation, and then go in reverse (ahead steam is removed and astern steam applied to stop the shaft). The different gauges are specific to each station, with the throttleman concerned about power to steam flow ratios, steam pressures, etc. The RO cares about primary water avg. (coolant) temp, pressures, etc. The EO is watching vital bus voltages, and charging the battery with a trickle charge.Thanks for the correction, Mike!
Thought you may like to know that (I used to sit on the far right, but on a newer version of that same panel).
The home computer of the year 2004 as envisioned in 1954. The caption reads:
Scientists from the RAND Corporation have created this model to illustrate how a "home computer" could look like in the year 2004. However, the needed technology will not be economically feasible for the average home. Also the scientists readily admit that the computer will require not yet invented technology to actually work, but 50 years from now scientific progress is expected to solve these problems. With teletype interface and the FORTRAN language, the computer will be easy to use...I just want to know what the giant steering wheel will be used for. (Via Metafilter.)

The real-life "Soup Nazi" from Seinfeld will be going national. The stores will be called "The Original Soup Man" and franchises can be purchased for $30,000 (plus 5% of the gross sales). BTW, the owner Al Yeganeh hates Jerry Seinfeld, and the franchises will not be allowed to use the term "Soup Nazi" in their promotional literature.
