Olaf Stapledon - forgotten visionary

Metafilter has an excellent note on "Olaf Stapledon: The Star Maker". The links are well worth visiting. Stapledon was a WW I veteran, and a contemporary of CS Lewis and Tolkien. All of them spent much of their lives reacting to the hell of 'the great war'.

Schneier on Security: Want to steal the identity of a Janus Mutual Fund holder?

If I held any Janus mutual fund shares I'd be writing them an letter ...

Schneier on Security: Vote Someone Else's Shares

If you have a valid proxy number, you can add 1300 to the number to get another valid proxy number. Once entered, you get another person's name, address, and account number at Janus! You could then vote their shares too.

This amount of information suffices for much identity theft. Schneier (and I) am right to spread the news. In the absence of any governmental action, we need to expose the staggering failures of these companies to implement even trivial security measures. I am sure Janus isn't the only mutual fund to make this mistake.

Perhaps the pasting they are now receiving will cause others to change their operating procedures.

The "better bicycle" approach to avoiding identity theft

The best way to prevent bicycle theft, is the "better lock"/"better bicycle" approach. No bike lock is invincible, so put your bike next to a better bike with an inferior lock (dings in the paint helps with being a less better bike btw, bike thieves are usually idiots). This is the same idea as how to outrun a bear -- just be faster than the guy next to you.

To that end, Hoofnagle (link via Schneier, god of security) has listed various measures one can take to make identity theft harder: EPIC West: Electronic Privacy Information Center West Coast Office: Hoofnagle's Consumer Privacy Top 10.

Implement these and the thieves will take your neighbors identity instead. This would be wonderful if your neighbor was, say, a US senator. (Note to Senators: Schneier says we need to make identity theft very expensive for banks -- then it will end. I believe that too.)

I'm impressed with the list. Most of them were new to me, and most are easy to apply. Recommended!

American corruption: Is Abramoff a tipping point?

American governance was very corrupt towards the end of the 19th century; during the so-called Gilded Age. Taft is one of the few presidents that may have been worse than George Bush. (I think Jackson was also worse, so GWB is only #3 -- he did pass Nixon though.) Things turned around fairly dramatically under Teddy Rosevelt and the trust busters. But these things go in cycles ...

We've been in a bad spot since Reagan; Carter was the last genuinely honest President. (Clinton was infinitely better than Bush, but no bastion of integrity). I used to support the Concord coalition, but about 15 years ago it became apparent that we weren't going to be able to deal with our budget issues honestly until we dealt with the growing corruption in American politics. Tim Penny, a former Minnesota Representative, has spoken well on this topic, as has, of course, John McCain and Russ Feingold. Mostly, however, both Democrats and Republicans have been silent. Corruption is now the only bipartisan consensus.

But ... what about the Abramoff Affair?. If the Plame Affair is really about Cheney and the corruption of power, the Abramoff affair is about plain old bribery and corruption. Nothing new, only more brutal and direct than we're accustomed too. Mysteriously, for some unfathomable reason, Abramoff seems to have crossed some sort of line (emphases mine):

Lawmakers Under Scrutiny in Probe of Lobbyist (Washington Post)

The Justice Department's wide-ranging investigation of former lobbyist Jack Abramoff has entered a highly active phase as prosecutors are beginning to move on evidence pointing to possible corruption in Congress and executive branch agencies, lawyers involved in the case said.

Prosecutors have already told one lawmaker, Rep. Robert W. Ney (R-Ohio), and his former chief of staff that they are preparing a possible bribery case against them, according to two sources knowledgeable about the matter who spoke on the condition of anonymity.

The 35 to 40 investigators and prosecutors on the Abramoff case are focused on at least half a dozen members of Congress, lawyers and others close to the probe said. The investigators are looking at payments made by Abramoff and his colleagues to the wives of some lawmakers and at actions taken by senior Capitol Hill aides, some of whom went to work for Abramoff at the law firm Greenberg Traurig LLP, lawyers and others familiar with the probe said.

Former House majority leader Tom DeLay (R), now facing separate campaign finance charges in his home state of Texas, is one of the members under scrutiny, the sources said. Sen. Conrad Burns (R-Mont.), Rep. John T. Doolittle (R-Calif.) and other members of Congress involved with Indian affairs, one of Abramoff's key areas of interest, are also said to be among them.

Prosecutions and plea deals have become more likely, the lawyers said, now that Abramoff's former partner -- public relations executive Michael Scanlon -- has agreed to plead guilty to conspiracy and to testify about gifts that he and his K Street colleagues showered on lawmakers, allegedly in exchange for official favors.

... Investigators are also gathering information about Abramoff's hiring of several congressional wives, sources said, as well as his referral of clients to Alexander Strategy Group, a lobbying and consulting firm run by former senior aides to DeLay. Financial disclosure forms show that the firm employed DeLay's wife, Christine, from 1998 to 2002.

... The former top procurement official in the Bush administration, David H. Safavian, has already been charged with lying and obstruction of justice in connection with the Abramoff investigation. Safavian, who traveled to Scotland with Ney on a golf outing arranged by Abramoff, is accused of concealing from federal investigators that Abramoff was seeking to do business with the General Services Administration at the time of the golf trip. Safavian was then GSA chief of staff.

Does Abramoff represent a tipping point, or will any reform effort prove premature? I'm betting we won't see any real reform succeed under the Bush administration. Put my money on "no tipping point yet". Even if the US does move down the reform road, Italy is a sobering example of how unpredictable reform can be -- they took a huge step forward in the 90s, but then elected Berlusconi -- a man who makes Abramoff seem chaste.

Why the Xbox 360 and the Web 2.0 are awful news for the retail PC industry

Very low end PCs do a quite adequate job with almost all computer applications, save games. Modern games require a monster machine; even children's games require a relatively decent box. So games have been a major driver of non-laptop retail PC purchases -- and, because of their software quality issues, a major source of pain for parents.

Thurott suggests that this trend will soon end. The Xbox 360 is relatively inexpensive, and, for the first time, the gaming experience exceeds that of even a high end Wintel PC. Consumers will keep their old machines, and buy an Xbox. Good news for Microsoft, very bad news for companies that sell into the home market.

In the old days a new version of Windows would drive PC sales. It's clear that Windows Vista will require a honking machine. But why bother? What does Vista promise the home user that Web 2.0 (Google, Yahoo, etc) apps can't deliver better for less money? Sure there's digital photography, home video, etc -- but for all that OS X is a better bet (and a good Intel OS X laptop may be cheaper than a Vista laptop.) In fact the Xbox 360 is good for Apple; by negating the 'games' advantage PC's have had, it really levels the software playing field.

Good comments from Thurott. If the logic holds expect Dell and HP to experience many more bad moments. Apple should weather this well, while Microsft should do just fine. They'll make their rent money from leasing Vista and Office to businesses, and grow with Xbox for home video and gaming.

It is interesting that, with Xbox, Microsoft is becoming more like Apple. They own the hardware platform and the XBox OS ...

Is someone in Harbin China reading this blog?

I posted yesterday on Harbin China, a large city that the New York Times described as a "town". Harbin has lost a large portion of its tap water due to benzene in the nearby river -- an environmental disaster on the Soviet scale. (Arguably Bhopal India still holds the cup.)

My post seemed unremarkable, but it solicited a comment:

kaikaiisagirl said...
I agree with you. Seriously the NYT reporters don't know enough about China. I go to college in Harbin, it is like the 8th or 9th biggest city in China.

It's nice to receive affirmation, but is someone in Harbin really reading Gordon's Notes? "Kaikaiisagirl's" blogger profile tells us s/he joined in August of 2005, but the profile has no other information. I suppose this could be a machine generated post, but I don't see why. On balance, it's most likely someone in Harbin did read that post. Someone who reads and writes English fluently.

How?

Gordon's Notes is a hobby blog. It exists because I'm compelled both to write and to rage against the fall of America. It does not have the practical utility of either Gordon's Tech or Be the Best You Can Be; they have value for me as convenient place to keep my own notes. I have long assumed its readership consists of me, my wife, and, on occasion, a few friends. (My own mother gave up on it a while back.) My limited brushes with fame have been links from Brad DeLong and David Brin. I'm also syndicated in .... medlogs, a project of the ever inventive Dr. Jacob Reider. My guess is that my Harbin readership came via the last.

Fascinating.

Not coincidentally, I read recently the blog reading and writing is increasing exponentially in China (I almost wrote 'exploding in China', but that phrase has become a cliche nowadays). At the moment the authorities are not too aggressive, though raging against the communist party, or discussing life in Harbin, would be substantially riskier than my rants against the Vice-President for Torture.

One curious side-effect of the Chinese blogging scene is that bloggers who read English also translate what they read into Chinese. Years ago Cisco helped the Chinese government erect powerful blocks to forbidden sites; and later to defeat proxy servers that reached those sites. These blocks are perhaps less effective against millions of blogs, each of which excerpts fractions of the forbidden material -- effectively acting as millions of proxy servers.

This is an interesting example of natural selection in action. The role of personal blog as a low profile proxy server is an accident of nature, but blogs that crave readership will adapt to it. They will become more reliable "proxy servers", the better to serve their Chinese readership.

Incidentally, if anyone wants to send me comments on what life has been like in Harbin, I'll post them anonymously here. You can email me at jfaughnan@spamcop.net. I'll also experiment with turning off the 'members only' filter on my Blogger comments, and see how well using the moderation filter alone will work.

Harbin, China - since when is "millions" a town?

The NYT reports on a benzene spill that has contaminated the water for the "town" of Harbin, China -- leaving 3 million without tap water. Only in China could the residence of 8 million people (3 million in the urban core) be called a town. Looking at the Google satellite image it seems to be a very concentrated city, maybe the size of the city of Minneapolis but four times the population.

It sounds like the crisis in Harbin is mercifully easing ... If Minneapolis were to lose its water supply things would not be pretty....

Is war becoming too expensive?

Wars used to consume lots of lives. The civil war, WW I -- incomprehensible volumes of lives. Raw human life, however, is not all that expensive. I shan't belabor the point since it's grossly offensive, but in low tech societies like WW I Europe it didn't cost much to raise a man to die in Verdun.

Wars are getting more expensive though - even for the aggressor. Fighers are educated and their economic output is far, far higher than in WW I. Their lifelong post-war care costs more. As we substitute technology for fighters that costs even more. The medium term costs of the "small" war in Iraq to the US are reaching above 200 billion.. The longer term direct costs for the US alone are now speculated to exceed 1 trillion..

Of course expense is relative. As a percentage of an 6-8 trillion dollar economy perhaps a 1 trillion dollar war is still a "small war". Is war really more expensive for 21st century America compared to 19th century Britain? I certainly hope war is becoming more costly in relative as well as absolute terms, but I don't know.

The perils of eBay, and why rough vendors like PayPal

I recently learned a few lessons about eBay and PayPal I'd like to pass on. The bottom line is that while I might use eBay to buy something from a regular person with a clear identity, I'll avoid eBay vendors. I've also reaffirmed and intensified my dislike of PayPal.

I bought a 'refurbished' Samsung i500 PalmOS cellphone from KM Electronics, an eBay vendor. I wasn't really trying to save money; the phone was the best option for my wife and her support staff (me) and it's no longer sold. I needed to go with 'refurb'. I took a gamble and lost, the phone has a defective digitizer. When I emailed KM Electronics I received a form response that made it pretty clear that they weren't going to be much help [1]. They also noted that if I produced a negative response on eBay they'd provide no further support or contact, irregardless of the terms of their warranty. Naturally I immediately submitted a negative response. (I have figured out ways to make the phone useful nonetheless.)

I learned a few interesting things about eBay and PayPal with this experience:

• eBay vendors put credit card icons next to PayPal buttons. It is true PayPal will manage a credit card transaction, but the vendor is paid by PayPal, not the credit card company. So good luck using AMEX to bludgeon a shady vendor -- they got their money from PayPal. The credit card relationship is with PayPal, not the vendor. Clever! A handy bit of indirection that's a win-win for PayPal, eBay and the vendor.
• eBay doesn't like negative reviews. I had to go through a little tutorial to write one. Helps explain why the reviews you see there are so often positive. I suspect the true 'negative experience' rate is several times higher than what's documented.
• This PayPal vendor is fairly typical in not having any contact method save email. (Sure I could try to track 'em down, but it's not worth it.) Email responses are automated.
• As noted above, vendors may go to some lengths to have positive comments; including intimidating anyone who might post a negative comment (voided warranty!). I think eBay ratings are very suspect.
  

I wonder how solid eBay's future really is. I'm kind of hoping Google's eCommerce solution vaporizes PayPal; though Google's product likely have the same beneficial (for vendors) "indirection" "feature".

[1] Selling refurbished phones is kind of a rough business, so it's not surprising they're a bit of a rough company. At least the phone's identifier was valid and Sprint could use it! I'm not their typical customer; I get the sense they specialize in selling things in bad net neighborhoods.

Update 11/24/05: After submitting my negative report, this is the (as expected) email I received from KM Electronics: "All service and warranty for your purchase has been cancelled." This is the type of vendor who sells on eBay -- submit a negative comment, void the support contract. Since this vendor sells a great deal on eBay, one presumes eBay approves. Clearly, the absence of negative ratings for some eBay vendors needs to be judged carefully.

Update 11/24/05b: This gets even more interesting. KM Electronics didn't respond to an email, but they responded very quickly to the negative rating. What an eBay vendor does under these conditions is give the customer a negative rating and some nasty comments, blocks the constumer from further correspondence, and then triggers an eBay mutual withdrawl option -- the simultaneous removeal of both negative comments.

Very interesting! eBay vendors like KM-Electronics (KMElectronics, etc) have more tools than I'd expected to keep their ratings positive. eBay is indeed a rough neighborhood, where advantage goes to the sharpest elbows. I wonder what's next -- goons at my door? If I had time to play the futures market I'd sell eBay short.

I'll post further updates here, I wouldn't be suprised if KM Electronics and eBay had more cards to play.

Update 12/20/05: MacSlash has a similar story. I wouldn't want to own stock in eBay.

Life as an outlaw - my experience buying a grayish market phone

How does a mild-mannered gray haired middle-aged guy become an outlaw? Well, in my case fighting with Apple's FairPlay DRM and struggling with my cellular carrier are leading me towards the darkseid.

My most recent experience was with the premature demise of my wife's coddled cellphone. Barely a year old the Samsung flip phone was malfunctioning. A far cry from the Nokia brick that was once stolen, tossed out a car window down an embankment, recovered from the mud days later, and worked flawlessly.

So I needed a replacement phone. I wanted the exact phone I have, the almost-great Samsung PalmOS (Grafitti ONE) SPH i500 so we could share accessories, chargers, etc. The phone would also replace her 1 year old CLIE TJ-27, famed for shoddy quality and the worthless needle stylus from heck. (Hmm, notice a trend here?).

Sprint, alas, had kiled the i500. There's no heir. The next closest thing costs $550 (Sprint rips off customers with the replacement phones). That did it. I wasn't going to spend that much on the infamously unreliable Treo, and we didn't have time to futz figuring our alternatives. Froogle and Pricescan only found eBay phones. I snapped and went to eBay.

There, with great reluctance and some research, I bought a 'refurbished' i500 from the most reliable seeming vendor I could find. I was forced to reactivate PayPal, a vendor I loathe almost as much as Sprint. (Hmm. George Bush. PayPay. Sprint. I think I'm getting seasonal affective disorder ...)

I purchased a phone from KMElectronics:

KM Electronics i500 Samsung Phone: Samsung SPH i500 Palm PDA Color Cell Phone Sprint - New: "YOUR PURCHASE INCLUDES-
1. Samsung i500 Phone & PDA
2. AC Charger
3. New Stylus & New Rechargeable Battery (jf: extended duration, not Samsung battery. The battery is huge; it makes the phone too thick for my use. So you have to budget for a new more useable battery too!)
4. New USB Cradle
5. Software / Manual on CD
6. For use with the Sprint PSC Network

(When new this phone came with two styli, a wrist cord, an ultra-slim and a reasonable sized battery, manuals, etc.)

Turns out the phone is $8 cheaper on their web site, it was $146 on eBay plus $12 to ship.

The good news is Sprint activated the phone without any problem or questions. Stolen phones with invalid ESN numbers is the big fear in this marketplace. In this case the ESN number was very hard to read (oddly poorly printed, I wonder if it was really the original ....) and the first reading I gave was invalid. Sprint didn't mention charging me, there's usually at least a $25 charge for a phone switch.

The bad news is that KM Electronics sent the wrong CD. Since I already have the CD this isn't a big deal for me, but it would be exceedingly annoying if I didn't. Also, a couple of buttons on the front of the phone are missing their labels. Too aggressive polishing?

The phone looks good and so far works well. I'll post an update on my further adventures in the twilight zone ...

Update 11/23/05: Alas, the digitizer is defective. Lost that gamble!

Update 11/23/05: More on this in my next post (on eBay and PayPal), but I did figure a way to work around the 'dead zone' on the i500. I can get most tasks done by using the OK/Cancel buttons on the phone and the option menus in the applications. I did receive a usenet report of a similar problem with a 'new' Samsung i500 bought a few months ago. Since the terms of service of KM Electronics made pursuing this with them a very costly and annoying option I think I'll see how well we can make this phone work.

Update 11/24/05: I do very much like having the same phone for both us, and being able to beam addresses between them, share batteries and retractable charge/sync cables, etc.

How special are we?

Science from Copernicus onwards has been about the 'descent of man'; from the apex of creation to a pointless blob of protoplasm on a meaningless dust speck in a vast cosmos.

But then there's the "cosmological coincidence":

Science & Technology at Scientific American.com: Supernovae Back Einstein's "Blunder"

... the finding brings to the fore another question: the so-called cosmological coincidence. Observations like this one seem to prove that regular matter and dark energy have similar densities at precisely this moment in time, even though the density of matter has been declining steadily since the big bang. Even Einstein couldn't answer why that would be.

There are a number of these coincidences in modern physics. The reasons why they bother physicists are somewhat subtle, but they fall into the class of non-Copernican phenomena; things that seem to make our 'existential state' atypical.

I like to monitor this sort of discussion.

We're leaving Iraq -- Why Murtha enraged Bush/Cheney.

Fred Kaplan was among the cautiously semi-pro war rationalists who hoped Bush knew more than we did and didn't expect his people to botch so many things. I was in that club too.

Now Kaplan, a student of military history and strategy, points out that the furor about 'cut and run' is nonensical. Once we gave up on calling on the 'individual ready reserves' we effectively declared that we're done in Iraq. Short of a draft, we can't last a year at current deployment levels.

So everyone who's "in the know" already knows we have to leave soon. (This explains, by the way, why the Iraqi government is now calling for a US departure timetable.) Ready or not.

Problem is, Rove has a story for how to do this, so it looks like we're leaving as planned. Murtha's declaration blew the story up. It makes the inevitable departure look like it's somehow a retreat before popular pressure. So Cheney blows his stack.

The odd thing is, Kaplan points out that Murtha actually has a plan. Chances are, more pain to Bush, it's the plan Rove wants too ...

What Murtha Meant - We're leaving Iraq anyway. At least he's got a plan. By Fred Kaplan

.... The Army recently announced that it will no longer call up the Individual Ready Reserves for duty in Iraq. The IRRs are retired—in many cases, long-retired—soldiers, who, by contract, are obligated to re-enter the force if called back to arms. This announcement is as clear a sign as any that, whatever George W. Bush and Richard Cheney might say about the likes of Murtha, they too know the troops are coming out. For without the IRRs, the Army will be unable to sustain the present levels for much longer.

It almost doesn't matter whether withdrawing or redeploying the troops is a good idea; it's simply going to happen because there is no way for it not to happen (short of a major act of political will, such as reviving the draft or keeping troops on the battlefield beyond reasonable endurance). This is what Murtha meant when he told Russert, "We're going to be out of there, we're going to be out of there very quickly, and it's going to be close to the plan that I'm presenting right now." (There are political reasons for this near-inevitability, as well. When Murtha predicted we'd be mainly out of Iraq by 2006, Russert asked, "By Election Day 2006?" Murtha responded, "You—you have hit it on the head.")

So, the pertinent question becomes: What is the best way for redeploying? In other words, by what timetable (whether one is explicitly announced or not), after what political and military actions? How many U.S. troops should be left behind, and what should they be doing? Where should the others be redeployed, and under what circumstances will they move back into Iraq? Do we have any realistic strategic goals left in this war (one big problem in this whole fiasco is that the Bush administration never had any from the outset), and how do we accomplish them?

There's a very serious debate to be conducted in this country—not only about the future of our involvement with Iraq, but also about the use of force, the response to threats, the war on terror, the shape of the Middle East. John Murtha's proposal leaves open a lot of questions, but—seen for what it really says, not for how it's been portrayed—it's a start.

When the right wing shows pompous rage, they've been caught with their hands in the cookie jar.

The lies Bush and Cheney told - from former chair of the senate intelligence committee

Bob Graham had better intelligence access than anyone short of Bush/Cheney. He learned before the war that the Bush administration had willfully chosen to close its eyes, and proceed on a predetermined path -- evidence be damned. Before the world knew, Graham knew Bush could not be trusted. Emphases mine.

Washington Post - What I Knew Before the Invasion
By Bob Graham
Sunday, November 20, 2005; Page B07

In the past week President Bush has twice attacked Democrats for being hypocrites on the Iraq war. "[M]ore than 100 Democrats in the House and Senate, who had access to the same intelligence, voted to support removing Saddam Hussein from power," he said.

The president's attacks are outrageous. Yes, more than 100 Democrats voted to authorize him to take the nation to war. Most of them, though, like their Republican colleagues, did so in the legitimate belief that the president and his administration were truthful in their statements that Saddam Hussein was a gathering menace -- that if Hussein was not disarmed, the smoking gun would become a mushroom cloud.

... As chairman of the Senate Select Committee on Intelligence during the tragedy of Sept. 11, 2001, and the run-up to the Iraq war, I probably had as much access to the intelligence on which the war was predicated as any other member of Congress.

I, too, presumed the president was being truthful -- until a series of events undercut that confidence.

In February 2002, after a briefing on the status of the war in Afghanistan, the commanding officer, Gen. Tommy Franks, told me the war was being compromised as specialized personnel and equipment were being shifted from Afghanistan to prepare for the war in Iraq -- a war more than a year away. Even at this early date, the White House was signaling that the threat posed by Saddam Hussein was of such urgency that it had priority over the crushing of al Qaeda. [jf: around this time the US had its great defeat, when bin Laden and the leadership escaped from their mountain fastness].

.... At a meeting of the Senate intelligence committee on Sept. 5, 2002, CIA Director George Tenet was asked what the National Intelligence Estimate (NIE) provided as the rationale for a preemptive war in Iraq. An NIE is the product of the entire intelligence community, and its most comprehensive assessment. I was stunned when Tenet said that no NIE had been requested by the White House and none had been prepared. Invoking our rarely used senatorial authority, I directed the completion of an NIE.

... We insisted, and three weeks later the community produced a classified NIE.

There were troubling aspects to this 90-page document. While slanted toward the conclusion that Hussein possessed weapons of mass destruction stored or produced at 550 sites, it contained vigorous dissents on key parts of the information, especially by the departments of State and Energy. Particular skepticism was raised about aluminum tubes that were offered as evidence Iraq was reconstituting its nuclear program. As to Hussein's will to use whatever weapons he might have, the estimate indicated he would not do so unless he was first attacked.

Under questioning, Tenet added that the information in the NIE had not been independently verified by an operative responsible to the United States. In fact, no such person was inside Iraq. Most of the alleged intelligence came from Iraqi exiles or third countries, all of which had an interest in the United States' removing Hussein, by force if necessary. [jf: this includes Iran, now suspected of having tricked Bush/Cheney into the invasion ...]

The American people needed to know these reservations, and I requested that an unclassified, public version of the NIE be prepared. On Oct. 4, Tenet presented a 25-page document titled "Iraq's Weapons of Mass Destruction Programs." It represented an unqualified case that Hussein possessed them, avoided a discussion of whether he had the will to use them and omitted the dissenting opinions contained in the classified version.

... From my advantaged position, I had earlier concluded that a war with Iraq would be a distraction from the successful and expeditious completion of our aims in Afghanistan. Now I had come to question whether the White House was telling the truth -- or even had an interest in knowing the truth.

On Oct. 11, I voted no on the resolution to give the president authority to go to war against Iraq. I was able to apply caveat emptor...

Cheney's ferocious attacks of the last few weeks bring the phrase "cornered rat" to mind. He and Bush were duped by Iran, their own massive egos, and their faith-based agenda.

Adventures in shopping continued: Amazon and daily pricing shifts

This is fascinating. I blogged previously on the dramatic fluctuations in Amazon and Amazon partner pricing for the very popular Canon Digital Rebel XT. I discovered then that if I put a variety of this item on my shopping cart, then 'deferred' purchase to "later", I could see the price changes as they occurred. Their were quite a few today -- similar to airline ticket price changes:

Please note that the price of Canon Digital Rebel XT 8MP Digital SLR Camera with EF-S 18-55mm f3.5-5.6 Lens (Silver) has decreased from $899.94 to $879.94 since you placed it in your Shopping Cart.

Please note that the price of Canon Digital Rebel XT 8MP Digital SLR Camera (Body Only - Silver) has increased from $838.94 to $854.99 since you placed it in your Shopping Cart.

Please note that the price of Canon 50mm f/1.8 II Camera Lens has increased from $74.94 to $75.99 since you placed it in your Shopping Cart.

Please note that the price of Canon Digital Rebel XT 8MP Digital SLR Camera (Body Only - Black) has decreased from $829.94 to $799.94 since you placed it in your Shopping Cart.

I'm sure someone has s written software that will check the deferred cart list items every 10 minutes, and execute a purchase based on the price fluctuations. Buying from Amazon.com these days seems to resemble buying shares on the NASDAQ. Inevitably the same sofware used to execute trading strategies will be used throughout the retail chain.

It's not just electronics by the way. The price of the Calvin and Hobbes compendium, a book, just jumped $10 on my shopping cart. I assume Amazon is adjusting costs in real-time based on sales, competitor pricing, customer profiles, the cost of gasoline, the futures market, and some randomness factor to measure the impact of different price points.

More complexity. More obscure costs. Where does it end?

PS. My "buy signal" for the next five days is something around $840 for the camera with the default lens.
