Why the Farangs smell

About 25 years ago I used to commute by bus from Pradu-Naam to the UN building in Bangkok. The bus was crowded and bloody hot. I had to put my arm up to hold on. The Thais downwind of me looked kinda green.

Farangs (foreigners, basically Euros), you see, not to put to fine a point on it, stink. The Thai, on the other hand, have relatively little body odor. Now we know why. It's in the ear wax...
Japanese Scientists Identify Ear Wax Gene - New York Times:

...They write that earwax type and armpit odor are correlated, since populations with dry earwax, such as those of East Asia, tend to sweat less and have little or no body odor, whereas the wet earwax populations of Africa and Europe sweat more and so may have greater body odor.
I feel better now. It really wasn't my fault.

BTW, as a physician I much prefer wet ear wax. Removing the dry stuff from a child's ear is a royal pain.

Fox news: in the pay of Philip Morris

DeLong echoes another corruption story - Fox News' science reporter was on the take from Philip Morris. His primary contribution was mocking claims about the health implications of environmental tobacco smoke.

A corrupt person, working for a corrupt news organization. Fox is low.

On the bright side, it's nice to know Philip Morris is as vile and evil as ever. I was afraid they'd gone soft.

Medicare Part D, Chimps and Bonobos

A prediction -- when the analysis is done the Bush drug plan (Medicare Part D) will be found to be largely a transfer of resources from the Weak to the Strong.

Which leads to the next thought. Is there any GOP program that's not a transfer from the Weak to the Strong? Is 'No Child Left Behind' an exception of intent, if not of implementation?

Transfer from the Weak to the Strong is a reasonably common primate thing; and of course it's perfectly Spencerian. Ironic then that the GOP should be the home of Darwin hating Christian Fundamentalists, but then they're really Yahwites in disguise.

Which leads, inevitably to the last thought. Humans, Chimps and Bonobos are all members of Genus Pan. To what extent can the Bush base be thought of as Chimps, and the pacifist Left be considered Bonobos? I'd bet, given descriptions of both primates, that 80% of the Bush base would say they were more like Chimps (strong, dominant, patriarchal, might survive humanity), and 95% of the pacifist Left would aspire to be Bonobos (matriarchal, cooperative, group sex, transgender, soon to be extinct, etc).

Which leads to the last plus one thought. Would functional MRIs of amygdala response differentiate between Bush fundamentalists and the pacifist Left? Is the Left/Right split more than politics? Maybe it's about speciation .... :-)

Can primates trust strangers?

Chimpanzees are generally hateful, and almost all primates are fundamentally xenophobic. Brain scans suggest humans (genus Pan) are programmed for fear and hatred of the Other. Will peace require genetic reengineering?

Robert Sapolsky, a primatologist, has written a review of human nature, published, oddly enough, in Foreign Affairs. It's fascinating. Primates turn out to be more flexible than had been though; dystopia is not inevitable. Humans may be particularly malleable.
Foreign Affairs - A Natural History of Peace - Robert M. Sapolsky

...In exploring these subjects, one often encounters a pessimism built around the notion that humans, as primates, are hard-wired for xenophobia. Some brain-imaging studies have appeared to support this view in a particularly discouraging way. There is a structure deep inside the brain called the amygdala, which plays a key role in fear and aggression, and experiments have shown that when subjects are presented with a face of someone from a different race, the amygdala gets metabolically active -- aroused, alert, ready for action. This happens even when the face is presented 'subliminally,' which is to say, so rapidly that the subject does not consciously see it.

More recent studies, however, should mitigate this pessimism. Test a person who has a lot of experience with people of different races, and the amygdala does not activate. Or, as in a wonderful experiment by Susan Fiske, of Princeton University, subtly bias the subject beforehand to think of people as individuals rather than as members of a group, and the amygdala does not budge. Humans may be hard-wired to get edgy around the Other, but our views on who falls into that category are decidedly malleable.
Emily wonders if the amygdala has the same response to the "deformed" and disabled. One can imagine the same mechanism underlying analysis of genetic fitness of potential mates.

Sapolsky describes recent studies of primate culture; their behavior can be changed. In some environments male Baboon nerds can mate well, particularly if the tyrants are fighting elsewhere. There is hope, though I suspect the genetic reengineering option will be on the table if we're still around in 70 years.

I wonder how Baboons would do with dogs? I suppose they'd eat the dogs fairly quickly and messily, but I've long wondered how dogs changed alliances in human primates.

Scary moment in the digital life: a corrupted image

I recently used iPhoto Library Manager to merge two iPhoto 5 libraries of several thousand images apiece. I did this in preparation for migration to iPhoto 6; IPLM has a longer track record with iP 5 than 6, so I chose to merge before upgrading.

Thus far it seems to have gone well, which is pretty impressive since #$!$! Apple doesn't support Library imports or merges in $!@#$!@ iPhoto. I'm still looking for problems and I'll report on my experience soon. I did get some malrotated images, but I expected that. OS X had some bad bugs with EXIF headers that Apple never admitted to but fixed; I expected older images to malrotate on import. I reverted to original and fixed them.

One image among thousands failed to import. IPLM produced a handy error message. I tracked down the image -- it was corrupt. Preview and GraphicConverter wouldn't render it and if I tried to open it in iPhoto the app locked up. (How stupid is that?)

Unnerving. I expect this image went bad years ago. Could have been a disk crash, could have been a rude copy of iPhoto, could have been a network copy glitch -- heck, it could have been cosmic rays. My regular backups only go back a few months, so they wouldn't help. I do have some CDs and DVDs that would probably cover this problem, but it would take a while to track those down. Fortunately I happened to have older versions of some iPhoto Libraries on my external drive, and I found a good copy in minutes.

This is exceedingly annoying. We are so far from having really good backup solutions. I depend on redundancy -- a primary automated network backup that runs daily and several different approaches to backup that are done irregularly. Odd are that if one method fails, the very different "backup backup" methods will work. It's the same principle applied to designing the space shuttle's control system.

Backups have saved me at least a dozen times over the past 20 years or so. They're very demanding to manage however.

The NSA affair: it's about how they selected their intercepts

Cringely's sources say pretty much exactly what I guessed last week (in part from his prior column, but also from connecting other dots) -- the technical aspects of the NSA affair are about social network analysis of phone metadata.

So Bush is right when he claims only a few calls are tapped, but what he doesn't talk about, and what reporters don't ask him, is how the NSA decides which phones to tap. It's the process of figuring out who to go after that's technically interesting, but the real story is about the ability of President to override Congress. That's a constitutional question that will go to the supreme court, and that's why Kerry and Kennedy are trying to filibuster Alito. I don't think they'll succeed, but I'm glad they're trying.
PBS | I, Cringely . January 26, 2006 - The Falafel Connection

... After last week's column, a number of readers wrote to explain that the National Security Agency's problem with complying with the Foreign Intelligence Surveillance Act (FISA) had to do with the sheer volume of wiretaps involved, which they guessed numbers in the millions or billions. Evidently, these worried readers think, the NSA has been long listening-in to ALL of our calls, and thought that might not go down well with the secret court that issues FISA warrants.

I don't think so.

The NSA has a very advanced program called Echelon for monitoring radio communication around the world, and probably intercepts a lot of phone calls that way, but for FISA-type wiretaps they tend to use the same outsourcing firms the phone companies use, and these generally tiny outfits can only handle a few thousand taps per year each.

By the way, if you are wondering whether YOUR phone could be easily tapped, just check to see if your phone company offers three-way dialing, because that's the feature we're talking about. If you can get it, they can get you. And if you are wondering whether VoIP service can't be tapped, the answer is both yes and no. For the moment, SIP services like Skype can't be tapped but that will change soon. And if you are a Vonage or Packet8 user, well they already have your number.

Here's what is most likely going on with the NSA and FISA from a guy who used to work for the NSA:

"What I think is going on here is that they're using social network analysis. They get some numbers or endpoints of interest, and start out with classical traffic analysis, which can all be done (as I think you pointed out) with pen registers or their moral equivalent. They look for other numbers, and follow the graph of connections by transitivity.

"It's well known that any graph of associations in the real world tends to generate cliques, and that the clique size for a social group of any sort tends to actually be fairly small. This is the 'six degrees of Kevin Bacon' effect. But in a social network, there will also be people with many edges coming to them, and many paths in the transitive closure of the graph of their relationships, and those people are often 'centers.'

"In fact, just that sort of analysis was done -- after the fact -- of the 9/11 hijackers (in this week's links).

"I would guess that the SNA is used to identify people of interest -- although there would be some false positives, like if they all rented apartments from the same rental management firm, or all ordered from the same we-deliver falafel place. But someone who shows up in the transitive network of a lot of calls from overseas, and is also a high edge-count in the SNA graph, is definitely someone to be interested in. I wouldn't be at all surprised if that's when they apply for a FISA warrant and start actually intercepting."

So what we have the NSA doing is probably data mining, calling records in order to identify the people they want to order intercepts on. They are doing it without warrants because they like being sneaky, don't think they could get past the FISA court a warrant for 100 million calling records, and because the FISA law from 1978 probably doesn't distinguish between a pen-trap and an intercept.

If that's really the case, this doesn't sound quite as bad as we've feared. I feel better thinking that they are culling calling records rather than listening-in to my conversations. And it makes a lot more sense, from a pure technical capability standpoint.

So why couldn't they just tell us? Why couldn't they have simply amended the FISA law to take such activities into account? Because they like to be sneaky, tend to distrust even the people who pay them (that's us), and because they for some reason think that the bad guys won't figure this out for themselves.

Duh.

But is it really Duh? Either al Qaeda is a lethal threat, and thus smart enough to figure this out on their own, or do they have got a thin bench full of dolts who couldn't think their way out of a paper bag?

Either way, Bush is wrong. If al Qaeda is a lethal threat, then they've already figured this out and we could pass laws making this legal without tipping them off. On the other hand, if they have a thin bench, then we don't need the Long War and we shouldn't be shredding the Constitution.

Challenger: 20 years

Twenty years ago seven amazing people died when the space shuttle Challenger "exploded" (it didn't). James Oberg was a senior NASA insider at that time. He critiques some myths that have grown up around the tragedy.

I was not surprised by his critiques, in each case they matched what I remember reading during and after the investigation of the disaster. It's true that most commentators didn't dwell on the fact that the cabin was intact when it hit the water, but even that wasn't a secret.

I was surpised by the myths, especially the one that "environmental regulations" had led to a sealant problem. I guess 20 years is long enough for legends to start.

I was in the Mojave desert when the first shuttle flight landed. I remember worrying about the damned tiles -- they'd broken loose in orbit (shades of later tragedy). In those days I dreamt about becoming a mission specialist and flying, but really I knew the competition was too stiff. Everyone who has flown, and many who just waited for a slot, are among the most exceptional human beings one can know.
7 myths about the Challenger shuttle disaster - Space News - MSNBC.com

Twenty years ago, millions of television viewers were horrified to witness the live broadcast of the space shuttle Challenger exploding 73 seconds into flight, ending the lives of the seven astronauts on board...

...spaceflight historians believe that each element of the opening paragraph is factually untrue or at best extremely dubious. They are myths, undeserving of popular belief and unworthy of being repeated at every anniversary of the disaster.

The Long War and the Quadrennial Defense Review: 20 years of the imperial president?

Bush's justification of his assertion of new presidential powers is that we're at War. What he doesn't emphasize is that he's thinking about a rather Long War ...
Early Warning by William M. Arkin - washingtonpost.com: "Goodbye War on Terrorism, Hello Long War

One phrase contained in the draft Quadrennial Defense Review document circulating amongst defense experts is sure to be a part of your life for years to come: The long war.

Defense experts want the long war to be the new name for the war on terror, a kind of societal short hand that will stand shoulder to shoulder with the Cold War, promoted to capital letters, an indisputable and universally accepted state of the world.

'This generation of servicemembers will be in what we're calling the Long War,' Army Lt. Gen. Ray Odierno, assistant to the chairman of the Joint Chiefs of Staff, said earlier this week.

'Our estimate is that for at least the next 20 years … our focus will be … the extremist networks that will continue to threaten the United States and its allies.'
A War against Evil could go on a long time, or until the End Times anyway. Given what Bush has done so far, is it inconceivable that he and his supporters will decide he should be able to run again? Yes, that's nuts. Of course. Forgive me...

Building a business without VCs

Kawaki's blog is still superb. He's gotta run out of steam sometime.

In some recent postings he confirmed my uninformed prejudice that VCs are a bit ridiculous, and are really only suited to a small minority of entrepreneurs.

Adopting a mutt - new age

We're adopting a dog. Things have changed since we picked up Molly more than 15 years ago at the Delta County pound. Back then there was no web, now we have petfinder.com and computer generated breed recommendations.

Impressive. The breed recommendations were pretty much what I'd have guessed. On the other hand, the Delta pound had some beautiful mongrels, and their mutts weren't $250 each.

They should, however, include a longevity question in the breed selector. I'm going to see if I can get them to add that in.

Defining the Drake equation: how common are rocky planets?

A new imaging technique allows visualization of a very large rocky planet orbiting a red dwarf:
Scientists spot a new Earthlike planet - Space.com - MSNBC.com:

The planet and star are separated by about 2.5 astronomical units.

The finding means planet hunters are one step closer to detecting their holy grail: a habitable Earthlike planet that can sustain liquid water and support life.
The distance sounds comparable to our asteroid belt. I wonder if that's coincidental.

The significance of the discovery may be the proof of the microlensing technique. We probably have years to go before we can begin to put more meaningful numbers into the Drake Equation, and thus constrain the solutions to Fermi's Paradox.

A retrospective look: the war on terror

I don't read Juan Cole regularly, but I thought his recent retrospective on the 'War on Terror' was well timed. In September of 2001 I was certainly asking myself -- was 9/11 a fluke, or was al Qaeda really something new? Did they "get lucky", or could they repeat?

Early on the safest guess was that they were something new. I still think that the falling costs of havoc have changed the old equations. Richard Reid, though made me wonder. Clearly al Qaeda was scraping the bottom of the barrel when they used him. Since then we've seen more evidence that al Qaeda's bench is weak. They can get lots of fairly ordinary people to commit suicide, but they seem to have trouble holding and recruiting the elite operatives that would make them truly dangerous.

In retrospect, al Qaeda's "success" on 9/11 seems to have had a large element of chance. They were "unlucky" on a prior attack on the WTC (the basement bombing) and they were almost supernaturally "lucky" on 9/11. Having Afghanistan as a base was critical, and being left relatively alone helped them too. They don't loom so large now, in large part due to the US military action in Afghanistan. Since then, however, Bush has seemed to be acting as an agent of bin Laden -- helping rather than hurting him. Cole expands:
Juan Cole - Informed Comment Top Ten Mistakes of the Bush Administration in Reacting to Al-Qaeda
Tuesday, January 24, 2006

... On September 11, 2001, the question was whether we had underestimated al-Qaeda. It appeared to be a Muslim version of the radical seventies groups like the Baader Meinhoff gang or the Japanese Red Army. It was small, only a few hundred really committed members who had sworn fealty to Bin Laden and would actually kill themselves in suicide attacks. There were a few thousand close sympathizers, who had passed through the Afghanistan training camps or otherwise been inducted into the world view. But could a small terrorist group commit mayhem on that scale? Might there be something more to it?...

Over four years later, there is no doubt. Al-Qaeda is a small terrorist network that has spawned a few copy-cats and wannabes. Its breakthrough was to recruit some high-powered engineers in Hamburg, which it immediately used up. Most al-Qaeda recruits are marginal people, people like Zacarias Moussawi and Richard Reid, who would be mere cranks if they hadn't been manipulated into trying something dangerous... They are left mostly with cranks, petty thieves, drug smugglers, bored bank tellers, shopkeepers, and so forth, persons who could pull off a bombing of trains in Madrid or London, but who could not for the life of them do a really big operation.

The Bush administration and the American Right generally has refused to acknowledge what we now know. Al-Qaeda is dangerous. All small terrorist groups can do damage. But it is not an epochal threat to the United States or its allies of the sort the Soviet Union was (and that threat was consistently exaggerated, as well).

In fact, the United States invaded a major Muslim country, occupied it militarily, tortured its citizens, killed tens of thousands, tinkered with the economy-- did all those things that Muslim nationalists had feared and warned against, and there hasn't even been much of a reaction from the Muslim world. Only a few thousand volunteers went to fight. Most people just seem worried that the US will destabilize their region and leave a lot of trouble behind them. People are used to seeing Great Powers do as they will. A Syrian official before the war told a journalist friend of mine that people in the Middle East had been seeing these sorts of invasions since Napoleon took Egypt in 1798. "Well," he shrugged, "usually they leave behind a few good things when they finally leave."

Because they exaggerate the scale of the conflict, and because they use it cynically, Bush and Cheney have grossly mismanaged the struggle against al-Qaeda and Muslim radicalism after September 11. Here are their chief errors:

1. Bush vastly exaggerates al-Qaeda's size, sweep and importance, while failing to invest in genuine counterterrorist measures such as port security or security for US nuclear plants.

2. Bush could have eradicated the core al-Qaeda group by putting resources into the effort in 2002. He did not, leaving al-Zawahiri and Bin Laden to taunt us, inspire our enemies and organize for years after the Taliban were defeated. It would be as though Truman had allowed Hitler to broadcast calls for terrorism against the US from some hiding place as late as 1949.

3. Bush opened a second front against Iraq before he had put Afghanistan on a sound footing.

4. Bush gutted the US constitution, tossing out the Fourth Amendment, by assiduously spying on Americans without warrants. None of those spying efforts has been shown to have resulted in any security benefits for the United States. Bush says that he wants to watch anyone who calls the phone numbers associated with al-Qaeda. But some of those phone numbers were for food delivery or laundry. We want a judge to sign off on a wire tap so that innocent Americans are not spied on by the government.

5. Bush attempted to associate the threat from al-Qaeda with Iran and Syria. Iran is a fundamentalist Shiite country that hates al-Qaeda. Syria is a secular Arab nationalist country that hates al-Qaeda. Indeed, Syria tortured al-Qaeda operatives for Bush, until Bush decided to get Syria itself. Bush and Cheney have cynically used a national tragedy to further their aggressive policies of Great Power domination.

6. Bush by invading Iraq pushed the Iraqi Sunni Arabs to desert secular Arab nationalism. Four fifths of the Sunni Arab vote in the recent election went to hard line Sunni fundamentalist parties. This development is unprecedented in Iraqi history. Iraqi Sunni Arabs are nationalists, whether secular or religious, and there is no real danger of most of them joining al-Qaeda. But Bush has spread political Islam and has strengthened its influence.

7. Bush diverted at least one trillion dollars in US security spending from the counter-terrorism struggle against al-Qaeda to the Iraq debacle, at the same time that he has run up half a trillion dollar annual deficits, contributing to a spike in inflation, harming the US economy, and making the US less effective in counterterrorism.

8. Counterterrorism requires friendly allies and close cooperation. The Bush administration alienated France, Germany and Spain, along with many Middle Eastern nations that had long waged struggles of their own against terrorist groups. Bush is widely despised and has left America isolated in the world. Virtually all the publics of all major nations hate US policy. One poll showed that in secular Turkey where Muslim extremism is widely reviled and Bin Laden is generally disliked, the public preferred Bin Laden to Bush. Bush is widely seen as more dangerous than al-Qaeda. This image is bad for US counterterrorism efforts.

9. Bush transported detainees to torture sites in Eastern Europe. Under European Union laws, both torture and involvement in torture are illegal,and European officials can be tried for these crimes. HOw many European counterterrorism officials will want to work closely with the Americans if, for all they know, this association could end in jail time? Indeed, in Washington it is said that a lot of our best CIA officers are leaving, afraid that they are being ordered to do things that are illegal, and for which they could be tried once another administration comes to power in Washington.

10. Bush's failure to capture Bin Laden and al-Zawahiri allows them to continue to grandstand, to continue to frighten the public, to continue to affect financial markets, and to continue to plot. Al-Zawahiri almost certainly plotted the 7/7 London subway bombings himself, and gloated about it when he issued Muhammad Siddique Khan's suicide statement. Misplaced Bush priorities are getting our allies hit. The CIA is reduced to firing predators at villages because our counterterrorism efforts have been starved for funds by the Iraq quagmire. If al-Qaeda does pull off another American operation, it may well give Bush and Cheney an opportunity to destroy the US constitution altogether, finally giving Bin Laden his long-sought revenge on Americans for the way he believes they have forced Palestinians and other Muslims to live under lawless foreign domination or local tyranny.
If al Qaeda is not an ephocal threat, do we really need to surrender our freedom, and change the balance of American government? Are we throwing away our freedom for no good reason?

My best explanation for Bush is that he's a deep KGB plant -- or an agent of a malign alien civilization. Next that he's incompetent. Lastly that he's the human expression of a rather scary desire of many Americans for the Great White Father. However, America elected him (once), and America elected his party to control the House, Senate and Supreme Court, and now America may choose to support his reinterpretations of the Constitution. If Bush is not challenged, history will judge that Americans took this road voluntarily and consciously. Thus will a great dream die.

A use for blacklists: Political spam

I've never had much use for blacklists. Most spammers don't use valid email addresses.

Times change. Political parties and candidates do use valid email addresses, and they are spamming me like mad. Oh what a fool I was to give my email address along with money to various democratic party candidates. (Lash, lash, lash.)

This guy is typical: spam email with no way to get off the list. Of course he won't get my money, but he's a fringe candidate anyway.

So now my blacklists and bounce tools will get a workout. It's nice to know blacklists are good for something.

Cervical ribs and cancer risk

I remember being taught that cervical ribs were a relatively harmless congenital anomaly. True, it's been years since I practiced clinical medicine, but is this widely known? Is it true?
Pharyngula

There isn't much variation in cervical vertebra number, though. There is an exception: sometimes, the 7th cervical vertebra is found to undergo a partial homeotic transformation and forms a pair of ribs, which are normally found only on thoracic vertebrae. Humans develop cervical ribs with a frequency of about 0.2%; do they also develop cancers? The answer is yes, with a frequency 125 times greater than the general population.
