20 largest banks by market cap: 1999-2009

Financial Times has this beautiful trend chart that shows how the banking landscape has changed drastically in the last decade. Giants like Citigroup, UBS and Bank of America that were dominating the industry until just a couple of years ago have not only declined, they have disappeared from the list. Move the slider at the bottom to see how it plays out over the years.
 
The most drastic change that strikes me is that 19 out of the top 20 banks were headquartered in the US, UK, Japan and Switzerland in 1999. Today that number has dropped to only 6.
 
A lot more information is visible if you view this chart on the FT website. Go Here.

The Quiet Coup

Simon Johnson, a professor at MIT’s Sloan School of Management, was the chief economist at the International Monetary Fund during 2007 and 2008. In a recent article, he compares the current crisis with others that IMF has helped manage in the past. His conclusion is that the underlying reasons for the current crisis in the U.S. are disturbingly similar to those found in many “immature” economies: Deep links between the finance industry and the government. [Link]

Every crisis is different, of course. Ukraine faced hyperinflation in 1994; Russia desperately needed help when its short-term-debt rollover scheme exploded in the summer of 1998; the Indonesian rupiah plunged in 1997, nearly leveling the corporate economy; that same year, South Korea’s 30-year economic miracle ground to a halt when foreign banks suddenly refused to extend new credit.

But I must tell you, to IMF officials, all of these crises looked depressingly similar. Each country, of course, needed a loan, but more than that, each needed to make big changes so that the loan could really work. Almost always, countries in crisis need to learn to live within their means after a period of excess—exports must be increased, and imports cut—and the goal is to do this without the most horrible of recessions. Naturally, the fund’s economists spend time figuring out the policies—budget, money supply, and the like—that make sense in this context. Yet the economic solution is seldom very hard to work out.

No, the real concern of the fund’s senior staff, and the biggest obstacle to recovery, is almost invariably the politics of countries in crisis.

Squeezing the oligarchs, though, is seldom the strategy of choice among emerging-market governments. Quite the contrary: at the outset of the crisis, the oligarchs are usually among the first to get extra help from the government, such as preferential access to foreign currency, or maybe a nice tax break, or—here’s a classic Kremlin bailout technique—the assumption of private debt obligations by the government. Under duress, generosity toward old friends takes many innovative forms. Meanwhile, needing to squeeze someone, most emerging-market governments look first to ordinary working folk—at least until the riots grow too large.

Eventually, as the oligarchs in Putin’s Russia now realize, some within the elite have to lose out before recovery can begin. It’s a game of musical chairs: there just aren’t enough currency reserves to take care of everyone, and the government cannot afford to take over private-sector debt completely.

In its depth and suddenness, the U.S. economic and financial crisis is shockingly reminiscent of moments we have recently seen in emerging markets (and only in emerging markets): South Korea (1997), Malaysia (1998), Russia and Argentina (time and again). In each of those cases, global investors, afraid that the country or its financial sector wouldn’t be able to pay off mountainous debt, suddenly stopped lending. And in each case, that fear became self-fulfilling, as banks that couldn’t roll over their debt did, in fact, become unable to pay. This is precisely what drove Lehman Brothers into bankruptcy on September 15, causing all sources of funding to the U.S. financial sector to dry up overnight. Just as in emerging-market crises, the weakness in the banking system has quickly rippled out into the rest of the economy, causing a severe economic contraction and hardship for millions of people.

But there’s a deeper and more disturbing similarity: elite business interests—financiers, in the case of the U.S.—played a central role in creating the crisis, making ever-larger gambles, with the implicit backing of the government, until the inevitable collapse. More alarming, they are now using their influence to prevent precisely the sorts of reforms that are needed, and fast, to pull the economy out of its nosedive. The government seems helpless, or unwilling, to act against them.

Top investment bankers and government officials like to lay the blame for the current crisis on the lowering of U.S. interest rates after the dotcom bust or, even better—in a “buck stops somewhere else” sort of way—on the flow of savings out of China. Some on the right like to complain about Fannie Mae or Freddie Mac, or even about longer-standing efforts to promote broader homeownership. And, of course, it is axiomatic to everyone that the regulators responsible for “safety and soundness” were fast asleep at the wheel.

But these various policies—lightweight regulation, cheap money, the unwritten Chinese-American economic alliance, the promotion of homeownership—had something in common. Even though some are traditionally associated with Democrats and some with Republicans, they all benefited the financial sector. Policy changes that might have forestalled the crisis but would have limited the financial sector’s profits—such as Brooksley Born’s now-famous attempts to regulate credit-default swaps at the Commodity Futures Trading Commission, in 1998—were ignored or swept aside.

Nathan Wolfe: hunting the next killer virus

In this TED video, Nathan Wolfe explains how he and his team are trying to stop the next killer virus from going mainstream, so to speak.

Virus hunter Nathan Wolfe is outwitting the next pandemic by staying two steps ahead: discovering new, deadly viruses where they first emerge -- passing from animals to humans among poor subsistence hunters in Africa -- before they claim millions of lives

Armed with blood samples, high-tech tools and a small army of fieldworkers, Nathan Wolfe hopes to re-invent pandemic control -- and reveal hidden secrets of the planet's dominant life form: the virus.

EV Watch: Aptera 2e

Wired has an article about this new three wheeled EV made by Aptera in California. It does 0-100 kph in 10 seconds and has a range of 160 km. [Link]

The Aptera 2e (aptera is Greek for wingless) does not fly, even though it does look a lot like wingless airplane. But it is very much a car: solid propulsion from a stop, a surprising ability to corner flat at speeds that might cause another car to drift or even tip, and the sound of acceleration which, while quiet, puts one in the mind of a mini turbine as it reaches cruising speed.

Even without the grinning dispensation it almost invariably got from our fellow road denizens, the 2e did things any aggressive driver might want it to. As Wilbur and I amiably discussed the tilt/flip criticism three-wheelers invariably attract, he suddenly gunned it at a green light, turned right on a dime, faded three lanes to his left while outrunning a cab turning left from the opposing lane and came to a comfortable stop perhaps 50 yards later.

Tony Schwartz: How Self-Interest Destroyed The Economy

Interesting article. It seems that we have grown to a point where it might not be practical to allow unrestricted pursuit of profit for everyone without endangering the world economy. [Link]

To illustrate, Hardin used the metaphor of an open pasture - "the commons" - to which herdsmen bring their cattle to feed. The herdsmen understandably want to feed as many of their cattle as possible - or as Hardin put it: "As a rational being, each herdsman seeks to maximize his gain." This works fine for everyone so long as there's enough grass to feed all the cattle. As demand rises, however, the effects of overgrazing take a progressive toll on the commons, until ultimately they're destroyed for everyone.

"Therein is the tragedy," Hardin writes. "Each man is locked into a system that compels him to increase his herd without limit - in a world that is limited. Ruin is the destination toward which all men rush, each pursuing his interest in a society that believes in the freedom of the commons."

Hardin's focus was on the ultimate costs prompted by the individual freedom to have children without limitation - namely overpopulation and insufficient resources for the many. The more narrowly limited resource in the financial world was profit. To generate ever more of it during the past decade, institutions, hedge fund managers, brokers, investment advisers mutual fund managers and individual investors all took ever bigger risks.

Japanese man certified as double A-bomb victim

Talk about toughness. This guy survived two Atom Bombs!! [Link]

Tsutomu Yamaguchi had already been a certified "hibakusha," or radiation survivor, of the Aug. 9, 1945, atomic bombing in Nagasaki, but has now been confirmed as surviving the attack on Hiroshima three days earlier as well, city officials said.

Yamaguchi was in Hiroshima on a business trip on Aug. 6, 1945, when a U.S. B-29 dropped an atomic bomb on the city. He suffered serious burns to his upper body and spent the night in the city. He then returned to his hometown of Nagasaki just in time for the second attack, city officials said.

"As far as we know, he is the first one to be officially recognized as a survivor of atomic bombings in both Hiroshima and Nagasaki," Nagasaki city official Toshiro Miyamoto said. "It's such an unfortunate case, but it is possible that there are more people like him."

Dan Gilbert: How comparison changes the expected value of things

Dan Gilbert is a Psychology professor at Harvard. In this interesting TED talk, he explains how the human brain deceives itself by assigning value to future outcomes using  just the past experiences, not taking into account the context in which those evaluations are being made.

Is 0.002 cents equal to $0.002?

A Verizon customer calls customer support to complain that before he went to Canada, he was quoted the roaming data cost as 0.002 cents per kB. When he got back he realized that he had been billed at a rate of 0.002 DOLLARS per kB. [Link]

In the following recorded conversation, he spends 25 minutes trying to convince 2 different Verizon customer support representatives that there is a difference between these two amounts.

Here is an actual sample from the conversation, keep in mind that this is 20 minutes into the “support” call:

Customer: I was quoted 0.002 cents. Its a terminology problem. You guys are quoting 0.002 cents as if it is 0.002 dollars simply because there is a decimal point involved.

Customer Support: we are not quoting 0.002 dollars, we are quoting 0.002 cents per kB.

Customer: Ohh God! Honestly…

Customer Support: I mean its the computer calculating the figure here ….

Customer: But I am being charged 0.002 dollars. Its a terminology problem.

Customer Support: OK. well its obviously a difference of opinion.

Customer: This is not opinion. This is, this is ….

Customer Support: Your bill for the data usage is entirely correct.

Customer:  Alright you know what, I am going to post this recording on my blog and then you guys at Verizon should learn math and learn how to quote it correctly.

Gordon Brown is frustrated by 'Psycho' in No 10

Barack Obama gives DVD’s as gift to Gordon Brown. The DVD’s are Region 1. The prime minister of Britain can’t watch them when he gets home :) [Link]

The films only worked in DVD players made in North America and the words "wrong region" came up on his screen. Although he mournfully had to put the popcorn away, he is unlikely to jeopardise the special relationship – or "special partnership", as we are now supposed to call it – by registering a complaint.

Astronaut Fail

NASA should spend some money and invent something that would stop this from happening again, like a strap.

New satellite to be launched for high-res gravity measurements

ESA is launching a new satellite to measure gravity variations around the earth in unprecedented detail. The data collected by the satellite will make it possible to measure the exact height from the surface at any pint on earth. In order to limit mechanical noise, it uses ion engines for thrust. Plus, it looks like it is actually made to travel in space :)  [Link]

As Goce bumps through the Earth's gravity field, the accelerometers will sense the fantastically small disturbances.

"We have one comparison that we often make," explained Rune Floberghagen, Esa's Goce mission manager.

"Imagine a snowflake, which has a fraction of a gram, slowly falling down on to the deck of a supertanker. The acceleration that the supertanker experiences from that snowflake is comparable to the sensitivity of our instrument,"

 

 

    1. The 1,100kg Goce is built from rigid materials and carries fixed solar wings. The gravity data must be clear of spacecraft 'noise'
    2. Solar cells produce 1,300W and cover the Sun-facing side of Goce; the near side (as shown) radiates heat to keep it cool
    3. The 5m-by-1m frame incorporates fins to stabilise the spacecraft as it flies through the residual air in the thermosphere
    4. Goce's accelerometers measure accelerations that are as small as 1 part in 10,000,000,000,000 of the gravity experienced on Earth
    5. The UK-built engine ejects xenon ions at velocities exceeding 40,000m/s; Goce's mission will end when the 40kg fuel tank empties
    6. S Band antenna: Data downloads to the Kiruna (Sweden) ground station. Processing, archiving is done at Esa's centre in Frascati, Italy
    7. GPS antennas: Precise positioning of Goce is required, but GPS data in itself can also provide some gravity field information

The Untold Story of the World's Biggest Diamond Heist

In 2003, a group of thieves robbed the Antwerp Diamond Center and escaped with about $100 Million worth of Diamonds and jewelry. In an otherwise perfect plan, a nervous member of the team made a mistake that led to the arrest of 4 out of the 5 thieves.

The loot was never recovered. The head of the robbers has just been released from the jail in Belgium. He has granted Wired’s Joshua Davis an exclusive interview about how they planned and executed the robbery. Fascinating stuff. I wonder when the movie is coming out. [Link]

The agreement was straightforward. For an initial payment of 100,000 euros, Notarbartolo would answer a simple question: Could the vault in the Antwerp Diamond Center be robbed?

He was pretty sure the answer was no. He was a tenant in the building and rented a safe-deposit box in the vault to secure his own stash. He viewed it as the safest place to keep valuables in Antwerp. But for 100,000 euros, he was happy to photograph the place and show the dealer how daunting it really was.

So he strolled into the Diamond District with a pen poking out of his breast pocket. At a glance, it looked like a simple highlighter, but the cap contained a miniaturized digital camera capable of storing 100 high-resolution images. Photography is strictly limited in the district, but nobody noticed Notarbartolo's pencam.

Fingerprinting Blank Paper Using Commodity Scanners

The authors of a new paper propose using scanners to view individual wood fibers in a sheet of paper and generating a fingerprint based on the unique patterns formed by these fibers. The paper will appear in the Proceedings of the IEEE Symposium on Security and Privacy, in May 2009. [Link]

I suppose someone somewhere just started looking at ways to create a sheet of paper with a pre-defined pattern of the constituent wood fibers :)

Viewed under a microscope, an ordinary piece of paper looks like this:

This paper presents a novel technique for authenticating physical documents based on random, naturally occurring imperfections in paper texture. We introduce a new method for measuring the three-dimensional surface of a page using only a commodity scanner and without modifying the document in any way. From this physical feature, we generate a concise fingerprint that uniquely identifies the document. Our technique is secure against counterfeiting and robust to harsh handling; it can be used even before any content is printed on a page. It has a wide range of applications, including detecting forged currency and tickets, authenticating passports, and halting counterfeit goods. Document identification could also be applied maliciously to de-anonymize printed surveys and to compromise the secrecy of paper ballots.

Disruptive technology alert: Google moves into voice call business

 It was bound to happen sooner or later, I guess. Google Voice was launched today. [Link]

Google Voice allows users to route all their calls through a single number that can ring their home, work and mobile phones simultaneously. It also gives users a single and easy-to-manage voice mail system for multiple phone lines. And it lets users make calls, routed via the Internet, free in the United States and for a small fee internationally.

Analysts singled out the Internet calling features as the aspect of the service that is potentially most disruptive to established companies. While inexpensive Internet calls have become commonplace, Google’s potential to reach a mass audience could make a difference, some analysts said.

Given the track record, Google's entrance in the market would probably mean that margins on voice calls will go to essentially zero. The telecom companies should speed up their conversion to bit-pipe providers in order to ensure survival. OR, they could decide to play chicken with Google.


New Battery tech: Fast charging, No loss of capacity

A breakthrough in Lithium battery tech at MIT has enabled scientists to construct batteries that charge and discharge orders of magnitude faster than existing ones. The only change is the way that the battery material is constructed.  

The new batteries also lose capacity slower. In some experiments, the capacity was actually found to increase over several charge/discharge cycles. This could lead to smaller, lighter batteries. Expected in a phone near you within two to three years. [Link]

Traditionally, scientists have thought that the lithium ions responsible, along with electrons, for carrying charge across the battery simply move too slowly through the material.

About five years ago, however, Ceder and colleagues made a surprising discovery. Computer calculations of a well-known battery material, lithium iron phosphate, predicted that the material's lithium ions should actually be moving extremely quickly.

"If transport of the lithium ions was so fast, something else had to be the problem," Ceder said.

Further calculations showed that lithium ions can indeed move very quickly into the material but only through tunnels accessed from the surface. If a lithium ion at the surface is directly in front of a tunnel entrance, there's no problem: it proceeds efficiently into the tunnel. But if the ion isn't directly in front, it is prevented from reaching the tunnel entrance because it cannot move to access that entrance. 

Also, at Ars Technica: [Link]

At low discharge rates, a cell prepared from this material discharges completely to its theoretical limit (~166mAh/g). As the authors put it, "Capacity retention of the material is superior." Running it through 50 charge/discharge cycles revealed no significant change in the total capacity of the battery.

But the truly surprising features of the cell came when the authors tweaked the cathode to allow higher currents to be run into the cell. Increasing the rate by a factor of 100 dropped the total capacity down to about 110mAh/g, but increased the power rate by two orders of magnitude (that's a hundred-fold increase) compared to traditional lithium batteries. Amazingly, under these conditions, the charge capacity of the battery actually increased as it underwent more charge/discharge cycles. Doubling the charge transport from there cut the capacity in half, but again doubled the power rate. At this top rate, the entire battery would discharge in as little as nine seconds. That sort of performance had previously only been achieved using supercapacitors. 

However, 

A more significant problem is that these batteries may wind up facing an electric grid that was never meant to deal with them. A 1Wh cell phone battery could charge in 10 seconds, but would pull a hefty 360W in the process. A battery that's sufficient to run an electric vehicle could be fully charged in five minutes—which would make electric vehicles incredibly practical—but doing so would pull 180kW, which is most certainly not practical.   

Raiders of the Lost Arc: Story Conference



The original 1978 story conference between Steven Spielberg, George Lucas, and Lawrence Kasdan for Raiders of the Lost Ark is available as a pdf file. Its pretty funny stuff in its own right. [Link]

G = George Lucas; S = Steven Spielberg

G — What can he chase them with? What if he jumps on a camel?

S — I love it. It's a great idea. There's never been a camel chase before.

L — Is this camel going to chase a car?

S — You know how fast a camel can run? Not only that, he can jump over vegetable carts and things. It could be a funny chase that ends in tragedy. You're laughing your head off and suddenly, "My God, she's dead."

S — We still have the big fight in the moving truck to do. And now we have a camel chase.

G — We've added another million dollars.

S — Not really. How much trouble can a camel be?
Later,
L — Do you have a name for this person?

G — I do for our leader.

S — I hate this, but go ahead.

G — Indiana Smith. It has to be unique. It's a character. Very Americana square. He was born in Indiana.

L — What does she call him? “Indy?”

G — That's what I was thinking. Or “Jones.” Then people can call him “Jones.”

Font smoothing, anti-aliasing, and sub-pixel rendering


Joel Spolsky describes the philosophical differences that Apple and Microsoft have about how to render fonts on-screen. [Link]

Apple and Microsoft have always disagreed in how to display fonts on computer displays. Today, both companies are using sub-pixel rendering to coax sharper-looking fonts out of typical low resolution screens. Where they differ is in philosophy.
  • Apple generally believes that the goal of the algorithm should be to preserve the design of the typeface as much as possible, even at the cost of a little bit of blurriness.
  • Microsoft generally believes that the shape of each letter should be hammered into pixel boundaries to prevent blur and improve readability, even at the cost of not being true to the typeface.
Now that Safari for Windows is available, which goes to great trouble to use Apple's rendering algorithms, you can actually compare the philosophies side-by-side on the very same monitor and see what I mean.

Sony releases new stupid piece of Shit - Onion News


Wall street on the Tundra

An interesting article about how Iceland got caught up in the credit bubble and is now close to going bankrupt. The author travels to Reykjavik, Iceland and reports some pretty strange goings on :)

Before October Magnus thought of Iceland as essentially free of danger; now he imagines hordes of muggers en route from foreign nations to pillage his board-game safe and thus refuses to allow me to use his real name. You'd figure New York would hear about this and send over planeloads of muggers, he theorizes. Most everyone has their savings at home. As he is already unsettled, I tell him about the unsettling explosions outside my hotel room. Yes, he says with a smile, there's been a lot of Range Rovers catching fire lately.

Talk at MIT about the current economic crisis


In a sobering talk at MIT in February, Harvard professor Martin Feldstein and MIT Sloan School professor Simon Johnson analyzed the current economic crisis and what can be done to get out of it. They are much more pessimistic about Europe than the US.
