Equations as icons
Monday, March 12, 2007, 06:08 PM - Beautiful Code, Media
When the 14-year-old Richard Feynman first encountered eiπ + 1 = 0, the future physics Nobel laureate wrote in big, bold letters in his diary that it was "the most remarkable formula in math". Stanford University mathematics professor Keith Devlin claims that "like a Shakespearean sonnet that captures the very essence of love, or a painting that brings out the beauty of the human form that is far more than just skin deep, Euler's equation reaches down into the very depths of existence". Meanwhile Paul Nahin – a retired US electrical engineer – says in his recent book, Dr Euler's Fabulous Formula, that the expression sets "the gold standard for mathematical beauty".Keep reading Equations as icons by Robert P. Crease, chairman of the Department of Philosophy, Stony Brook University, and historian at the Brookhaven National Laboratory, US.
For some people this expression, named after the 18th-century Swiss mathematician Leonhard Euler, even seems to have become an icon, having special significance apart from its mathematical context. It once even served as a piece of evidence in a criminal trial. In August 2003 an eco-terrorist assault on several car dealerships in the Los Angeles area resulted in millions of dollars worth of damage when a building was set alight and over 100 vehicles were destroyed or defaced. The vandalism included graffiti on the cars that read "gas guzzler" and "killer" – and, on one Mitsubishi Montero, eiπ + 1 = 0. Using this as a clue and later as evidence, the FBI arrested William Cottrell, a graduate student in theoretical physics at the California Institute of Technology, who was later tried and convicted. Cottrell testified at his trial that "Everyone should know Euler's theorem".
61 comments DRM, net neutrality, etc

From slashdot:
Speaking before the House Subcommittee on Telecommunications and the Internet, Tim Berners-Lee advocated for net neutrality, saying that the Web deserves 'special treatment' as a communications medium to protect its nondiscriminatory approach to content. Berners-Lee's more controversial statements came on the topic of DRM, in which he suggested that instead of DRM, copyright holders should provide information on how to legally use online material, allowing users the opportunity 'to do the right thing.' This led to an odd exchange with Representative Mary Bono who compared Berner-Lee's suggestion to 'having a speed limit but not enforcing the speed limit.'"Also from /. today
"C-Net says last year saw a 131 percent jump in digital sales, but overall the industry still saw about a 4 percent decline in revenue. Some executives at this week's Digital Music Forum East conference lashed out at Jobs, blaming Apple and its CEO for their troubles. The impression at the conference was that Jobs' call three weeks ago for DRM-free music was anything but sincere. As the article puts it, 'Apple has maintained a stranglehold on the digital music industry by locking up iTunes music with DRM ... and "it's causing everybody else who is participating in the marketplace — the other service providers, the labels, the users — a lot of pain. If they could simply open it up, everybody would love them."
Can History be Open Source?

WIKIPEDIA AND THE FUTURE OF THE PASTby Roy Rosenzweig, originally published in The Journal of American History Volume 93, Number 1 (June, 2006)
History is a deeply individualistic craft. The singly authored work is the standard for the profession; only about 6 percent of the more than 32,000 scholarly works indexed since 2000 in this journal’s comprehensive bibliographic guide, “Recent Scholarship,” have more than one author. Works with several authors—common in the sciences—are even harder to find. Fewer than 500 (less than 2 percent) have three or more authors.Historical scholarship is also characterized by possessive individualism. Good professional practice (and avoiding charges of plagiarism) requires us to attribute ideas and words to specific historians—we are taught to speak of “Richard Hofstadter’s status anxiety interpretation of Progressivism.”2 And if we use more than a limited number of words from Hofstadter, we need to send a check to his estate. To mingle Hofstadter’s prose with your own and publish it would violate both copyright and professional norms.
A historical work without owners and with multiple, anonymous authors is thus almost unimaginable in our professional culture. Yet, quite remarkably, that describes the online encyclopedia known as Wikipedia, which contains 3 million articles (1 million of them in English). History is probably the category encompassing the largest number of articles. Wikipedia is entirely free. And that freedom includes not just the ability of anyone to read it (a freedom denied by the scholarly journals in, say, jstor, which requires an expensive institutional subscription) but also—more remarkably—their freedom to use it. You can take Wikipedia’s entry on Franklin D. Roosevelt and put it on your own Web site, you can hand out copies to your students, and you can publish it in a book—all with only one restriction: You may not impose any more restrictions on subsequent readers and users than have been imposed on you. And it has no authors in any conventional sense. Tens of thousands of people—who have not gotten even the glory of affixing their names to it—have written it collaboratively. The Roosevelt entry, for example, emerged over four years as five hundred authors made about one thousand edits. This extraordinary freedom and cooperation make Wikipedia the most important application of the principles of the free and open-source software movement to the world of cultural, rather than software, production.
Despite, or perhaps because of, this open-source mode of production and distribution, Wikipedia has become astonishingly widely read and cited. More than a million people a day visit the Wikipedia site. The Alexa traffic rankings put it at number 18, well above the New York Times (50), the Library of Congress (1,175), and the venerable Encyclopedia Britannica (2,952). In a few short years, it has become perhaps the largest work of online historical writing, the most widely read work of digital history, and the most important free historical resource on the World Wide Web. It has received gushing praise (“one of the most fascinating developments of the Digital Age”; an “incredible example of open-source intellectual collaboration”) as well as sharp criticism (a “faith-based encyclopedia” and “a joke at best”). And it is almost entirely a volunteer effort; as of September 2005, it had two full-time employees. It is surely a phenomenon to which professional historians should attend.
To that end, this article seeks to answer some basic questions about history on Wikipedia. How did it develop? How does it work? How good is the historical writing? What are the potential implications for our practice as scholars, teachers, and purveyors of the past to the general public?

Steve Job's thoughts on music. Music meaning DRM:
Some have argued that once a consumer purchases a body of music from one of the proprietary music stores, they are forever locked into only using music players from that one company. Or, if they buy a specific player, they are locked into buying music only from that company’s music store. Is this true? Let’s look at the data for iPods and the iTunes store – they are the industry’s most popular products and we have accurate data for them. Through the end of 2006, customers purchased a total of 90 million iPods and 2 billion songs from the iTunes store. On average, that’s 22 songs purchased from the iTunes store for each iPod ever sold.I'm impressed. And so is Jon Lech Johansen.
Today’s most popular iPod holds 1000 songs, and research tells us that the average iPod is nearly full. This means that only 22 out of 1000 songs, or under 3% of the music on the average iPod, is purchased from the iTunes store and protected with a DRM. The remaining 97% of the music is unprotected and playable on any player that can play the open formats. Its hard to believe that just 3% of the music on the average iPod is enough to lock users into buying only iPods in the future. And since 97% of the music on the average iPod was not purchased from the iTunes store, iPod users are clearly not locked into the iTunes store to acquire their music.

inside eBay's Innovation Machine
Thursday, January 4, 2007, 04:39 PM - Beautiful Code, Media
Business is steady on an early december afternoon at the iSold It consignment store on Skeet Club Road in High Point, N.C., as customers drop off items to be sold on eBay. Bikes, electronics, power tools --a steady flow of stuff, forming a tributary to the nearly $50 billion flood of goods and services that will be sold on the giant online marketplace in 2006.
iSold It LLC, with almost 200 outlets from coast to coast, has become one of the largest sellers on eBay Inc. by making it simple for anyone to move merchandise across the sprawling auction site. Simple for the folks consigning the stuff, that is -they just fill out a quick form, then go home to watch their online auction and wait for a check- but a fair amount of work for iSold It's employees, who must check the items in, list them in the most advantageous areas on eBay, keep track of bidding and sales, and follow through with shipping and payment.
Multiply that by the 50,000 different auctions iSold It manages in a typical month -about 15,000 at any given moment, closer to 18,000 during the December holiday rush- and, well, "it gets very complex," says Dave Crocker, senior vice president of business development at the privately held Monrovia, Calif., company. To deal with that complexity, iSold It is switching from internally developed software to a more sophisticated application from a Salt Lake City firm called Infopia Inc., which links directly to various eBay sites and handles pricing, listing and other key tasks more efficiently.
Infopia is not just another software vendor. It's part of a growing community of some 40,000 independent developers, all building products using eBay's own application programming interfaces, or APIs -the connection points that let a program share data and respond to requests from other software. These applications are tailor-made to work seamlessly with eBay's core computing platform. eBay provides its APIs to the developers for free; its cost is limited to maintaining the code and providing some support resources for the developers.
The payoff: a network of companies creating applications that help make eBay work better, grow faster and reach a broader customer base. (eBay's other business units, Skype and PayPal, also have open APIs and developer programs.) eBay says that software created by its developer network—there are more than 3,000 actively used applications, including a configurator that allows high-volume sellers to list items more efficiently, and a program that notifies buyers of auction status via mobile phone -plays a role in 25 percent of listings on the U.S. eBay site. The company has about 105 million listed items at any given time; roughly half of its sales come from within the United States.
Sharing APIs is common practice for software companies, but eBay, along with its fellow online-retail pioneer, Amazon.com, is breaking new ground in its industry by establishing a large community of outside developers. And the implications of this strategy go much further than the world of auctions and electronic storefronts. "It's about allowing people outside your company to write services that communicate with you-—it could be companies in your supply chain, sharing information about inventories or billing," says Adam Trachtenberg, senior manager of platform evangelism at eBay (i.e., the guy responsible for the care and feeding of the developer program).
"In the next few years you will see more and more companies with third-party developer networks, even companies you might not think of as likely candidates," adds Zeus Kerravala, senior vice president of enterprise research at Yankee Group. That could mean companies in far more traditional businesses than eBay, including manufacturers, he says. "These days, executives are telling me 'we're more like a software company than a hardware company'—and I say, then act like one. The long-term winners and losers in markets are determined by ecosystems around them, and developer networks fit that model. Developer communities allow companies to do things over the Internet with resources they don't have themselves," he says. Companies can't just flip a switch and join the game, though, says Daniel Sholler, a research vice president at Gartner Inc. They may need to first embrace the design model of service-oriented architecture, which hides the underlying complexity of a system from users, and allows components of an IT infrastructure to be reused and recombined to support particular processes instead of dedicated tasks. "This is part of the maturation of the Web, the trend toward service-enabling all kinds of systems and sharing information more freely," Sholler says.
Companies such as Infopia are now creating mash-ups—applications built around APIs from eBay and other firms such as SalesForce.com Inc. and FedEx Corp.—that extend the relationship between different companies and their customers. The mash-ups loosely join unrelated entities, portending a new level of interactivity between companies and customers of all kinds. "This is what Web 2.0 does for business," says Infopia CEO Bjorn Espenes. "Everyone can pick and share information in different ways that are much more automated."

Journalism without journalists
Wednesday, August 2, 2006, 05:55 PM - Media
On the Internet, everybody is a millenarian. Internet journalism, according to those who produce manifestos on its behalf, represents a world-historical development -not so much because of the expressive power of the new medium as because of its accessibility to producers and consumers. That permits it to break the long-standing choke hold on public information and discussion that the traditional media -usually known, when this argument is made, as "gatekeepers" or "the priesthood"- have supposedly been able to maintain up to now. "Millions of Americans who were once in awe of the punditocracy now realize that anyone can do this stuff -and that many unknowns can do it better than the lords of the profession," Glenn Reynolds, a University of Tennessee law professor who operates one of the leading blogs, Instapundit, writes, typically, in his new book, "An Army of Davids: How Markets and Technology Empower Ordinary People to Beat Big Media, Big Government and Other Goliaths."

Hollywood to Google (on video over IP): don't take it away from me!

Major article from the consultant office i2 Partners War of the Worlds: Hollywood Opts Out of the 'Google Economy':
Hollywood believes large-scale broadband video distribution would only destroy proven value, fail to provide alternative value, and alter a business model that is still far from being in decline. With near-total control of the most valuable program libraries and the business models governing their distribution, a shift towards broadband media will come largely on Hollywood’s terms and at an incremental pace.
