Is Greenspan demented?

NewDonkey.com

Greenspan is 79 years old on March 6th. The vast majority of humans have measurable and significant cognitive impairment by age 79. Early dementia is common, though given Greenspan's base intellect he will function well even when significantly impaired.

One of the common features of the natural and inevitable decay of the brain is a return to old beliefs, frequently with a loss of judgment and flexibility. Beliefs like these:

The Moose's post today linked to an AEI article by Bill Bradford about Greenspan's much-reported but oft-forgotten association with the Objectivist cult of novelist and proto-libertarian Ayn Rand. I thought I knew the story pretty well, but two things really startled me in Bradford's piece: (1) Greenspan went straight from Rand's inner circle (ironically but accurately known as 'The Collective') into the 1968 presidential campaign of Richard Nixon. In fact, Greenspan was already knee-deep in conventional Republican politics when he signed onto Rand's bizarre excommunication of her protege and former lover Nathaniel Brandon. (2) When asked during various Senate confirmation hearings over the years if he still adhered to Randian dogmas like abolition of all regulations and a return to the gold standard, Greenspan gave no sign of a change of heart or mind.

I don't think Greenspan has become particularly corrupt in his old age. I do think he may suffer from the typical cognitive impairment of a 79 yo man; an impairment that will be somewhat masked by his high baseline IQ.

Excellent commentary on the mad adventures of a 3 engined British Airways flight

Great post, and Joe summed it up very well: "When someone says it's not about the money — it's about the money."

OK British Airways. It's time to fold up shop.

The universe as an infinite pile of overlapping grapefruits

Science & Technology at Scientific American.com: Misconceptions about the Big Bang -- [ COSMOLOGY ] -- Baffled by the expansion of the universe? You're not alone. Even astronomers frequently get it wrong

I think it's simpler to believe we just live in a simulation, or, if you prefer, the dream of a God. Then we push all this bizarre stuff off to whatever runs the dreamer. Don't you agree?

Observers living in the Andromeda galaxy and beyond have their own observable universes that are different from but overlap with ours. Andromedans can see galaxies we cannot, simply by virtue of being slightly closer to them, and vice versa. Their observable universe also used to be the size of a grapefruit. Thus, we can conceive of the early universe as a pile of overlapping grapefruits that stretches infinitely in all directions. Correspondingly, the idea that the big bang was 'small' is misleading. The totality of space could be infinite. Shrink an infinite space by an arbitrary amount, and it is still infinite.

...Does this prediction of faster-than-light galaxies mean that Hubble's law is wrong? Doesn't Einstein's special theory of relativity say that nothing can have a velocity exceeding that of light? This question has confused generations of students. The solution is that special relativity applies only to "normal" velocities--motion through space. The velocity in Hubble's law is a recession velocity caused by the expansion of space, not a motion through space. It is a general relativistic effect and is not bound by the special relativistic limit. Having a recession velocity greater than the speed of light does not violate special relativity.

...Astronomers have observed about 1,000 galaxies with redshifts larger than 1.5. That is, they have observed about 1,000 objects receding from us faster than the speed of light. Equivalently, we are receding from those galaxies faster than the speed of light. The radiation of the cosmic microwave background has traveled even farther and has a redshift of about 1,000. When the hot plasma of the early universe emitted the radiation we now see, it was receding from our location at about 50 times the speed of light

...Thus, we can observe light from galaxies that have always been and will always be receding faster than the speed of light. Another way to put it is that the Hubble distance is not fixed and does not mark the edge of the observable universe.

...If space were not expanding, the most distant object we could see would now be about 14 billion light-years away from us, the distance light could have traveled in the 14 billion years since the big bang...the current distance to the most distant object we can see is about three times farther, or 46 billion light-years.

... People often assume that as space expands, everything in it expands as well. But this is not true. Expansion by itself--that is, a coasting expansion neither accelerating nor decelerating--produces no force. Photon wavelengths expand with the universe because, unlike atoms and cities, photons are not coherent objects whose size has been set by a compromise among forces. A changing rate of expansion does add a new force to the mix, but even this new force does not make objects expand or contract.

...In fact, in our universe the expansion is accelerating, and that exerts a gentle outward force on bodies. Consequently, bound objects are slightly larger than they would be in a nonaccelerating universe, because the equilibrium among forces is reached at a slightly larger size. At Earth's surface, the outward acceleration away from the planet's center equals a tiny fraction (10–30) of the normal inward gravitational acceleration. If this acceleration is constant, it does not make Earth expand; rather the planet simply settles into a static equilibrium size slightly larger than the size it would have attained.

I love how the author slips in the part about "size set by a compromise among forces". Existence as a committee deliberation. I definitely don't understand any of this.

Detective Duane does impressive work

ChoicePoint Data Cache Became a Powder Keg (washingtonpost.com)

Sheriff detective Duane Decker gets a call from ChoicePoint. He sets up a routine sting operation and uncovers a massive identity theft.

The ChoicePoint story is interesting in so many ways. The most important questions are around the primary market for personal information and the indentity theft industry but there are other neat aspects. For example, are all LA Sheriffs as clever and effective as Mr. Decker? For another, I think it's fascinating how Nigeria seems have developed a "comparative advantage" (economics term) in identity theft and in fraud.

Influenza is picking up late this year

CDC - Influenza (Flu) | Weekly US Map: Influenza Summary Update

As of Feb 19th Oregon and Washington are hard hit, as is much of the SouthEast. The CDC doesn't split out Northern California from southern, but I've heard anectdotal reports that suggest San Francisco may resemble Portland. Minnesota is still on the quiet side. The CDC says some of the current strains are different enough that even vaccinated persons may be susceptible. Early treatment with antivirals can significantly shorted duration of illness; this works best when a family member is known to have the flu and others start to develop very early symptoms. A script for antivirals for family members may be written when the index case is diagnosed (helps if you're seeing a family doc!).

It will be interesting to see next week's map.

Creating a reliable system out of unreliable components: Google and massive redundancy

Google's secret of success? Dealing with failure | CNET News.com

For Google, reliability is an emergent property of the system. An individual cell (computers) is not that robust. Cells die and are taken out of commission every day. The system, however, is very robust.

Sound familiar?

That's how your body works. Individual cells are not all that reliable. They are constantly mutating, breaking down, getting infected, becoming immortal (bad). The human body, however, is reasonably reliable -- we don't crash every day. Reliability is an emergent property of large numbers of unreliable components.

Google wasn't the first enterprise to product reliability through redundancy. The space shuttle flies with (I think) six computers. Five are identical, one is quite different. They all have to agree on their outputs.

What's the lesson for home? I'm not sure. I need to think about that one. System reliability (phone, pda, server, desktop, laptop, iPod ... ) is a big headache in our household. I know I need more reliable and less troublesome tools.

Environmentally induced ADD: Medicine in the Harvard Business Review

Harvard Business Online - Overloaded Circuits: Why Smart People Underperform

I don't routinely read the HBR (though I'm going to start), but a colleague brought this article to my attention. The author, Edward Hallowell, claims that there's an epidemic of environmentally induced attention-deficit disorder, which he calls "ADT" (attention deficit trait). His thesis is that our hunter-gatherer prefrontal cortex is being increasingly overloaded by distractions and environmental stressors, inducing a failure of "executive" function and a set of behaviors resembing adult ADD. The difference between ADT and ADD is that when the environment changes, the ADT behaviors resolve. Hallowell has written a number of books on ADD/ADHD, and from an Amazon comment I gather he has ADD (not ADT) himself. So while he's not a researcher, he does have some street cred on the topic.

From my own experience in corporate America I'd say the premise has loads of "face validitity". Since this article was written for the HBR he focuses on senior executives with "ADT", but the thesis is just as true for a parent overloaded by the care of a child with a disease or cognitive/behavioral disorder.

Hallowell's recommendations are pretty reasonable. He doesn't favor buying a CrackBerry (BlackBerry). He favors regular personal connection and interaction with trusted colleagues (something that's becoming infrequent in many companies), sleep, exercise, healthy diet, limiting email times, avoiding carbohydrate loading, and a few basic techniques:

1. Keep a section of one's desk clear at all times.
2. Break down large tasks into small ones.
3. Keep a portion of the day protected for thinking.
4. Contain email to specific hours. (I've taken to disabling everything that might notify me of inbox activity)
5. At the end of each day identify no more than five critical priorities for the next day.
6. Begin each day by tackling at least one of the critical priorities -- before attending to email and messages.
7. Follow the GTD methodology for articles and messages (He doesn't put it this way, but that's what he's talking about.)
8. Schedule important work for the times of day you know you're most productive. (Unfortunately for me, one of my more productive intervals is between 4:30pm and 6:00pm. Weird!)
9. Find ways to doodle, fidget, pace, or listen to music -- whatever it takes to settle down.
10. Have a friendly face-to-face chat with someone you like every 4-6 hours.
11. When the frontal lobes are in panic mode -- try these techniques to settle them down
    - do an easy rote task: reset watch, read a dictionary (wow!), do a crossword puzzle
    - move around, take the stairs down and up
    - brainstorm, talk with a colleague

Sometimes Hallowell seems to be talking about persons with true ADD rather than ADT, but I suspect those distinctions are artificial. Hallowell would probably say "Some people have ADD all the time, but there are some environments that will induce ADD in almost anyone".

You can read the article at your library or pay $7 to download a PDF. It will be interesting to see if this idea holds up over time and even gets some serious data behind it. I don't get the feeling that the world is getting less complex, or that email, the BlackBerry, instant messaging, mobile phones, voice mail(s) and ceaseless travel are going to go away.

Environmentally induced ADD is here to stay. Does anyone remember "Future Shock"? Nowadays the world of 1984, which Alvin Toffler described as so unstettling and distressing, seems quaint and tranquil. I can hardly wait for 2025 -- which is when I'm "supposed" to retire. Sooner or later, 99% of us may be on meds all the time just to cope with our ever more crazed world. (BTW, this last idea was nicely explored in at least one recent "high end" science fiction novel about 5 -8 years ago.)

Podcasting: iPodder.org

iPodder.org

Podcasting is about recording audio in MP3 and posting it on the web. Software detects the recording and adds it to a syndication database. Other software helps you find and download the MP3. Then you play it.

I was trying to figure out how I could use this. I have a lot of CME to listen to, not to mention music. The only thing I could think of were children's stories. If someone were very good at reading kids stories I'd love to have the audio for car trips and doctors visits.

There are, as my friend Lin would point out, some significant intellectual property issues with that scenario.

Death of the PDA, take III

PalmInfocenter.com: Study Predicts Steep Decline for PDA Market

The PDA has come and gone a few times, most famously with the Newton. Now the Palm and PocketPC devices again appear to be going away:

... the traditional PDA is heading for significant declines in sales, and in fact is nearing the end of its life as a major product segment, according to In-Stat. Shipments reached only 8.7 million units in 2004, down from 10 million in 2003, the high-tech market research firm says.

The outlook for upcoming years is not good, as the PDA market will have a negative Compound Annual Growth Rate (CAGR) of -21.5% during the 2004-2009 period. By 2009, it is expected that this segment will be composed of devices designed for specific vertical markets and low-end products. The market decline will occur as users switch to other products, such as smartphones and portable media players, a natural evolution of the category...

The market has been dying for years, but I don't agree that "smartphones" and "portable media players" are a natural extension of the market.

The original Palm vision was a personal organizer that was also an open, lightweight, low capacity, application platform. It's strength was synchronization and desktop integration and utter, astounding, reliability. It was inexpensive (a tenth the cost of a laptop, vs today's devices that are can be 60% of the price of a very nice iBook.) and semi-disposable with a strong desktop support.

There's nothing comparable today. Nothing.

Why not? That's the interesting question. I think there was once a limited but decent market for this kind of device. That market was fragmented and obliterated:

1. It seems odd now, but for a time Microsoft felt threatened by the Palm. They responded with a huge effort that produced a lot of very defective products that fell short of vast technical ambitions. Users of these products will never touch a PDA again -- having a personal organizer fail is a traumatic experience. The PocketPC is probably as robust as the unreliable Palm PDAs left, but the market to support it is quite small.
   
   
2. Microsoft Exchange took over the corporate world. Microsoft had no incentive to support Palm synching with Exchange server. Very few PalmOS users survived the experience of synching a PalmOS device with an Exchange server. PocketPC users didn't do much better at first; ActiveSync was a disaster for years. Then the CrackBerry came in and wiped out the residual corporate PDA users. Again, market attrition.
   
   
3. Pocket competition. Even as American men got heavier (so less able to carry a pocket device), the PDAs got bigger and heavier. Soon the PDA was pushed out of the pocket -- to compete with iPods (new), laptops (old) and phones (old). That's a lot of competition.
   
   
4. Palm lost its way in a series of bungles and mistakes. They also completely lost their original vision. The internet boom and bust didn't help.
   
   
5. Even as PDAs got big and costly, laptops got smaller and cheaper. If a computing device doesn't fit in the pocket, it might as well run OS X or XP.
   

So the market is going to go away for a while. It'll be back one day. We boomers desperately need a wearable (or pocketable) "brain" that's reliable, robust and integrated with the desktop -- a true PDA. It's going to take a few years for a new group of naive (meaning not bitter and crispy) users to emerge, and adopt a new PDA solution. Not a phone, but something that with a bluetooth earpiece that does VOIP communication and that can replace a phone. Not an iPod, but it will have a 100 GB internal drive and will play music. Not running HotSync, but perhaps SyncML. Not a BlackBerry, but it needs to work seamlessly with an Exchange server. With multiple input options and a good combination of both voice command, word recognition, and stylus interaction. Yes, and with a camera too.

Who knows, maybe it will come from Apple. Jobs isn't getting any younger. Soon he'll need a pocket brain ...

Buying a cell phone - another market failure?

Amazon.com: Cell Phones: PCS Phone palmOne Treo 650 (Sprint)

I need a new cell phone. My old one, which I never liked, is falling apart. I figured I'd have a few options. Wrong. Amazon reviews capture what I'm seeing everywhere: poor design, poor reliability, poor customer experiences. It's a combination of a crummy service provider attitude (such as disabling key phone functionality to encourage purchase of high price services), lousy service provider customer support, and phones designed to sell rather than to provide a lasting value to the customer.

In other words, yet another market failure.

I'm going for the simplest possible phone with the fewest features, and using the Apple iSync compatibility list as a quick guide to clueful manufacturers.

Supreme Court bans juvenile executions -- Martian invasion completed

BBC NEWS | Americas | US court bans juvenile executions

The US Supreme Court has abolished the death penalty for those who commit murder when under the age of 18.

This is proof of an alien invasion; how else to explain this outbreak of rationality? The court was, of course, divided. At least they weren't debating the wisdom of executing 12 year olds, the question was for teens aged 16-18.

It's a slippery slope though. As O'Connor writes when arguing for execution:

One of the court's dissenting judges, Sandra Day O'Connor, argued that: 'Chronological age is not an unfailing measure of psychological development, and common experience suggests that many 17-year-olds are more mature than the average young 'adult'.

Indeed. I would not be surprised to learn that most murderers have the psychological maturity of an average 2 year old. Such speculations though lead us down into the depths of relativism, where humans go at peril of their most deeply held beliefs.
