Peter Drucker, 1909-2005

Peter F. Drucker, 95, who was often called the world's most influential business guru and whose thinking transformed corporate management in the latter half of the 20th century, died Nov. 11 at his home in Claremont, Calif. No cause of death was reported, but he was under hospice care. His work influenced Winston Churchill, Bill Gates, Jack Welch and the Japanese business establishment. His more than three dozen books, written over 66 years and translated into 30 languages, also delivered his philosophy to newly promoted managers just out of the office cubicle.

Mr. Drucker pioneered the idea of privatization and the corporation as a social institution. He coined the terms "knowledge workers" and "management by objectives." His seminal study of General Motors in 1945 introduced the concept of decentralization as a principle of organization, in contrast to the practice of command and control in business.

"There is only one valid definition of business purpose: to create a customer," he said 45 years ago. Central to his philosophy was the belief that highly skilled people are an organization's most valuable resource and that a manager's job is to prepare and free people to perform. Good management can bring economic progress and social harmony, he said, adding that "although I believe in the free market, I have serious reservations about capitalism."

It was a typical remark for a man who believed in the empowerment of workers and the futility of big government, which he called "obese, muscle-bound and senile."

The most effective president, he told Forbes magazine 11 months ago, was Harry Truman, because "everybody who worked for him worshiped him because he was absolutely trustworthy." Ronald Reagan took second place: "His great strength was not charisma, as is commonly thought, but his awareness and acceptance of exactly what he could do and what he could not do."


Mr. Drucker's extraordinary professional longevity took him from the rise of Hitler to the excesses of Enron. The Austrian native wrote for a mass business audience, but he studded his books with unusual references -- from Tang-dynasty China to seventh-century Byzantium to his heroine, novelist Jane Austen. In 1981, he said the best-run organization in the United States was the Girl Scouts of America.

Peter Ferdinand Drucker was born Nov. 19, 1909 in Vienna. He worked as a financial reporter in Frankfurt, Germany, while he earned a doctoral degree in public and international law at Frankfurt University. He received his doctorate in 1931. The next year, he published an essay on a leading conservative philosopher that offended the Nazi government; his pamphlet was banned and burned. Mr. Drucker, increasingly worried by the Nazis, moved to London, where he worked for a merchant bank. In 1937, he moved to the United States and began working as a correspondent for several British newspapers.

His first book, "The End of Economic Man: The Origins of Totalitarianism" (1939), was favorably reviewed by Churchill, and it was made required reading for every new British officer.
Mr. Drucker taught part time at Sarah Lawrence College and then full time at Bennington College in Vermont. After publication of his second book, "The Future of Industrial Man" (1943), General Motors Corp. invited him to study GM's corporate structure. The two-year study put him in close contact with GM's legendary patriarch Alfred P. Sloan.


The book that resulted, "The Concept of the Corporation" (1945), introduced the ideas of decentralizing decision-making and managing for the long-term by setting a series of short-term objectives. It was an immediate bestseller, although GM wasn't pleased initially; Mr. Drucker said he was told that a manager found with a copy would be fired.

The ideas in it, however, launched the field of management and essentially created the field of consulting. He became professor of management in the graduate business school at New York University in 1950, and four years later, he published "The Practice of Management," which argued that management was one of the major social innovations of the century and posed three now-classic business questions: What is our business? Who is our customer? What does our customer consider valuable?

In the early 1950s, when other business leaders figured the worldwide market for computers was in the single digits, he predicted that computer technology would thoroughly transform business. In 1961, he alerted his followers to the rise of Japan as an industrial power, and two decades later, he warned of its impending economic stagnation. In 1997, he predicted a backlash to burgeoning executive pay, saying, "In the next economic downturn, there will be an outbreak of bitterness and contempt for the super-corporate chieftains who pay themselves millions."

Mr. Drucker demanded that public and private organizations operate ethically and decried managers who reap bonuses by laying off employees. "This is morally and socially unforgivable, and we will pay a heavy price for it," he said.


He wasn't always right, and academics disdained his popular approach, criticizing him for relying on anecdotes and accusing him of manipulating facts to fit his positions. But evidence of his influence is found in just how ordinary his insights now seem: A company should streamline bureaucracy. Managers should look for more efficient models for organizing work. Results are obtained by exploiting opportunities, not solving problems.

In 1971, Mr. Drucker moved to California, where he helped develop the country's first executive master's of business administration program for working professionals at Claremont Graduate University. Its management school, where he taught until 2002, is named after him.
"In the world of management gurus, however, there is no debate. Peter Drucker is the one guru to whom other gurus kowtow," said the McKinsley Quarterly in 1996.


Among Drucker's many honors, President George W. Bush awarded him the Presidential Medal of Freedom in 2002.


Survivors include his wife, Doris Drucker of Claremont, Calif.; four children; and six grandchildren.

POJO Application Frameworks: Spring Vs. EJB 3.0

POJO Application Frameworks: Spring Vs. EJB 3.0 by Michael Juntao Yuan -- Spring and EJB 3.0 are both reactions, in their own ways, to the complexity of EJB 2.1 and the complaints piled upon it. Both support developing with Plain Old Java Objects (POJOs) and give the framework responsibility for handling transactions, security, persistence, etc. But the two use substantially different approaches. In this article, Michael Yuan puts the two frameworks up against one another to see how they stack up.

Quantum Cryptogrphy - Some links

Key to combat hacking - Quantum Cryptography

Quantum cryptography could well be the first application of quantum mechanics at the individual quanta level. Quantum cryptography is an approach to securing communications based on certain phenomena of quantum physics. Unlike traditional cryptography, which employs various mathematical techniques to restrict eavesdroppers from learning the contents of encrypted messages, quantum cryptography is focused on the physics of information. The process of sending and storing information is always carried out by physical means, for example photons in optical fibres or electrons in electric current.

Eavesdropping can be viewed as measurements on a physical object---in this case the carrier of the information. What the eavesdropper can measure, and how, depends exclusively on the laws of physics. Using quantum phenomena such as
quantum superpositions or quantum entanglement one can design and implement a communication system which can always detect eavesdropping. This is because measurements on the quantum carrier of information disturb it and so leave traces.

Some commercially-available products have appeared based on quantum cryptography, for example,
ID Quantique or MagiQ.

REST - Second Generation Web Services

REST - Second Generation Web Services
REST stands for REpresentational State Transfer, and is an architectural style for large-scale software design. REST was first articulated by Roy Fielding in his dissertation, which describes Fielding's view of the architecture of the "best" subset of the Web.

The REST hypothesis is that the semantics of HTTP constitutes a coordination language that is sufficiently general and complete to encompass any desired computational communication pattern.

The REST hypothesis is that the semantics of HTTP constitutes a coordination language that is sufficiently general and complete to encompass any desired computational communication pattern. I.e., the hypothesis is that GET / PUT / POST / etc. can provide all coordination semantics between discretely modeled units of programs (and in case it's not all, or there's other practical reasons for it, HTTP is sufficiently extensible to support new methods being added). REST is comparable to message passing (provably completely general) or function calling with parameters in its ability to express any computational communication / coordination pattern. Obviously, there are other operations needed to actually do the work.

One interesting aspect of REST vs. these new XML-based web services is how REST jives with the Interface Segregation Principle (The dependency of one class to another one should depend on the smallest possible interface.)-- that interfaces are defined by the client's needs, not the server's needs... and for dependency management we need smaller, fewer protocols -- not more.

The premise of REST adherents is that HTTP in and of itself has the set of "verbs" (GET, POST, etc) we need to implement web services. All we need new are lots of "nouns" (URIs).

Software Factories: Refactoring an Industry

Software Factories: Refactoring an Industry

Problems with the current concept of reuse
Software development has always been costly and time-consuming process. Specialized requirements and lack of skilled resources are just two of the difficulties facing companies today. Pressure to deliver software, on time and within budget, have pushed developers to look for a way to increase value delivered, while decreasing development time.

For many years now, efficient reuse of existing assets, either through object-oriented programming, component based development, patterns-based architecture, has been one of the core objectives for the IT industry as a whole. Reuse is seen as a means to combat many of the problems facing development teams. However, for many years and several different technology paradigms, this level of reuse has eluded the industry as a whole.

Software Factories: Assembling applications with Patterns, Models, Frameworks, and Tools aims to change this by modifying the definition of reuse as used by the IT industry and bring a more manufacturing approach to software reuse.

How To Save The Internet

Internet would shut down by 2006

Professor Hannu H. Kari of the Helsinki University of Technology is a smart guy, but most people thought he was just being provocative when he predicted, back in 2001, that the Internet would shut down by 2006. "The reason for this will be that proper users' dissatisfaction will have reached such heights by then that some other system will be needed," Kari said, "unless the Internet is improved and made reliable." Last fall, Kari bolstered his prophecy with statistics. Extrapolating from the growth rates of viruses, worms, spam, phishing and spyware, he concluded that these, combined with "bad people who want to create chaos," would cause the Internet to "collapse!"—and he stuck to 2006 as the likely time.
