Tesla CTO Straubel Likes Biography of Tesla

J.B. Straubel, Chief Technology Officer of Tesla Motors. Source of photo: online version of the NYT article quoted and cited below.

(p. 2) J. B. Straubel is a founder and the chief technical officer of Tesla Motors in Palo Alto, Calif. The company makes electric vehicles that some compare to Apple products in terms of obsessive attention to design, intuitive user interface and expense.

READING I like to read biographies of interesting people, mostly scientists and engineers. Right now, it’s “Steve Jobs,” by Walter Isaacson. One of my favorites biographies was “Wizard: The Life and Times of Nikola Tesla,” by Marc Seifer, which I read even before Tesla Motors started.
. . .
WATCHING I really like the movie “October Sky.” It’s about a guy who grew up in a little coal-mining town around the time of Sputnik. He fell in love with the idea of building rockets and the movie follows him through his high school years when he’s building rockets and eventually he ends up becoming an engineer at NASA. I watch it every year or so. It’s inspirational. I always come out of it wanting to work harder.

Paul Allen’s Account of the Founding of Microsoft

Source of book image: http://www.entrepreneur.com/dbimages/slideshow/idea-man-paul-allen.jpg

(p. C6) The first half of “Idea Man” sets forth Mr. Allen’s version of the Microsoft creation myth, depicting Mr. Gates as a petulant, ambitious and money-minded mogul-to-be and Mr. Allen as an underappreciated visionary. Pictures of them from the 1970s and early ’80s also tell this story, making Mr. Allen look like a hirsute, powerful older brother and Mr. Gates like a kid.
. . .
“Idea Man” is long overdue. It turns out to be as remote, yet as surpassingly strange, as its author, whose receipt of a diagnosis of Stage 4 non-Hodgkin’s lymphoma in 2009 has made it that much more important for him to tell his story. Though it is written in the smoothly proficient style of many a collaborator-assisted memoir, it is a book filled with wild extremes: breakthrough, breakup, power, indulgence, blue-sky innovation. And it winds up offering Mr. Allen’s guarded, partial answer to a universal question: what if you could make your wildest dreams come true?

MOOCs “Will Really Scale” Once Credible Credentialing Process Is Mastered

A “MOOC” is a “massive open online course.”

(p. 1) Last May I wrote about Coursera — co-founded by the Stanford computer scientists Daphne Koller and Andrew Ng — just after it opened. Two weeks ago, I went back out to Palo Alto to check in on them. When I visited last May, about 300,000 people were taking 38 courses taught by Stanford professors and a few other elite universities. Today, they have 2.4 million students, taking 214 courses from 33 universities, including eight international ones.

Anant Agarwal, the former director of M.I.T.’s artificial intelligence lab, is now president of edX, a nonprofit MOOC that M.I.T. and Harvard are jointly building. Agarwal told me that since May, some 155,000 students from around the world have taken edX’s first course: an M.I.T. intro class on circuits. “That is greater than the total number of M.I.T. alumni in its 150-year history,” he said.
. . .
(p. 11) As we look to the future of higher education, said the M.I.T. president, L. Rafael Reif, something that we now call a “degree” will be a concept “connected with bricks and mortar” — and traditional on-campus experiences that will increasingly leverage technology and the Internet to enhance classroom and laboratory work. Alongside that, though, said Reif, many universities will offer online courses to students anywhere in the world, in which they will earn “credentials” — certificates that testify that they have done the work and passed all the exams. The process of developing credible credentials that verify that the student has adequately mastered the subject — and did not cheat — and can be counted on by employers is still being perfected by all the MOOCs. But once it is, this phenomenon will really scale.
I can see a day soon where you’ll create your own college degree by taking the best online courses from the best professors from around the world — some computing from Stanford, some entrepreneurship from Wharton, some ethics from Brandeis, some literature from Edinburgh — paying only the nominal fee for the certificates of completion. It will change teaching, learning and the pathway to employment. “There is a new world unfolding,” said Reif, “and everyone will have to adapt.”

Modern Cities Are “Successful Former Slums” that Allowed “Vibrant Economic Activity”

(p. 82) Babylon, London, and New York all had teeming ghettos of unwanted settlers erecting shoddy shelters with inadequate hygiene and engaging in dodgy dealings. Historian Bronislaw Geremek states that “slums constituted a large part of the urban landscape” of Paris in the Middle Ages. Even by the 1780s, when Paris was at its peak, nearly 20 percent of its residents did not have a “fixed abode”–that is, they lived in shacks. In a familiar complaint about medieval French cities, a gentleman from that time noted: “Several families inhabit one house. A (p. 83) weaver’s family may be crowded into a single room, where they huddle around a fireplace.” That refrain is repeated throughout history. A century ago Manhattan was home to 20,000 squatters in self-made housing. Slab City alone, in Brooklyn (named after the use of planks stolen from lumber mills), contained 10,000 residents in its slum at its peak in the 1880s. In the New York slums, reported the New York Times in 1858, “nine out of ten of the shanties have only one room, which does not average over twelve feet square, and this serves all the purposes of the family.”
San Francisco was built by squatters. As Rob Neuwirth recounts in his eye-opening book Shadow Cities, one survey in 1855 estimated that “95 percent of the property holders in [San Francisco] would not be able to produce a bona fide legal title to their land.” Squatters were everywhere, in the marshes, sand dunes, military bases. One eyewitness said, “Where there was a vacant piece of ground one day, the next saw it covered with half a dozen tents or shanties.” Philadelphia was largely settled by what local papers called “squatlers.” As late as 1940, one in five citizens in Shanghai was a squatter. Those one million squatters stayed and kept upgrading their slum so that within one generation their shantytown became one of the first twenty-first-century cities.
That’s how it works. This is how all technology works. A gadget begins as a junky prototype and then progresses to something that barely works. The ad hoc shelters in slums are upgraded over time, infrastructure is extended, and eventually makeshift services become official. What was once the home of poor hustlers becomes, over the span of generations, the home of rich hustlers. Propagating slums is what cities do, and living in slums is how cities grow. The majority of neighborhoods in almost every modern city are merely successful former slums. The squatter cities of today will become the blue-blood neighborhoods of tomorrow. This is already happening in Rio and Mumbai today.
Slums of the past and slums of today follow the same description. The first impression is and was one of filth and overcrowding. In a ghetto a thousand years ago and in a slum today shelters are haphazard and dilapidated. The smells are overwhelming. But there is vibrant economic activity.

Technology Brings Choices and Control, Which Brings Happiness

(p. 78) For the past 30 years the conventional wisdom has been that once a person achieves a minimal standard of living, more money does not bring more happiness. If you live below a certain income threshold, increased money makes a difference, but after that, it doesn’t buy happiness. That was the conclusion of a now-classic study by Richard Easterlin in 1974. However, recent research from the Wharton School at the University of Pennsylvania shows that worldwide, affluence brings increased satisfaction. Higher income earners are happier. Citizens in higher-earning countries tend to be more satisfied on average.
My interpretation of this newest research–which also matches our intuitive impressions–is that what money brings is increased choices, rather than merely increased stuff (although more stuff comes with the territory). We don’t find happiness in more gadgets and experiences. We do find happiness in having some control of our time and work, a chance for real leisure, in the escape from the uncertainties of war, poverty, and corruption, and in a chance to pursue individual freedoms–all of which come with increased affluence.
I’ve been to many places in the world, the poorest and the richest spots, the oldest and the newest cities, the fastest and the slowest cultures, and it is my observation that when given a chance, people who walk will buy a bicycle, people who ride a bike will get a scooter, people riding a scooter will upgrade to a car, and those with a car dream of a plane. Farmers everywhere trade their ox plows for tractors, their gourd bowls for tin ones, their sandals for shoes. Always. Insignificantly few ever go back. The exceptions such as the well-known Amish are not so exceptional when examined closely, for even their communities adopt selected technology without retreat.

Cooking Allowed the Toothless to Live

Source of book image: http://d.gr-assets.com/books/1344733081l/13587130.jpg

(p. C12) . . . the narrative, ragtag though it may be, is a good one and it starts with the single greatest achievement in cookware–the cooking pot. Originally made of clay, this simple invention allowed previously inedible foods to be cooked in water, a process that removed toxins, made them digestible and reduced the need for serious chewing, a deadly problem for the toothless. (Archaeologists find adult skeletons without teeth only at sites dating from after the invention of the cooking pot.)
. . .
When “Consider the Fork” turns to cultural history, Ms. Wilson’s points sometimes contradict one another. On one hand, she slyly condemns the rich throughout history and their use of cheap cooking labor. Yet she also relates how the Lebanese writer Anissa Helou remembers kibbé being made in Beirut by her mother and grandmother: They pounded the lamb in a mortar and pestle for an hour, a process described in loving terms. So is cooking labor a bedrock of family values or class exploitation?

New Technology Gets Better, Cheaper and More Diverse

(p. 75) Devices not only get better, they also get cheaper while they get better. We turn around to peer through our window into the past and realize there wasn’t window glass back then. The past also lacked machine-woven cloth, refrigerators, steel, photographs, and the entire warehouse of goods spilling into the aisles of our local superstore. We can trace this cornucopia back along a diminishing curve to the Neolithic era. Craft from ancient times can surprise us in its sophistication, but in sheer quantity, variety, and complexity, it pales against modern inventions. The proof of this is clear: We buy the new over the old. Given the choice between an old-fashioned tool and a new one, most people–in the past as well as now–would grab the newer one. A very few will collect old tools, but as big as eBay is, and flea markets anywhere in the world, they are dwarfed by the market of the new. But if the new is not really better, and we keep reaching for it, then we are consistently duped or consistently dumb. The more likely reason we seek the new is that new things do get better. And of course there are more new things to choose from.

Were Phone Phreaks Creative Incipient Entrepreneurs or Destructive “Sophomoric Savants”?

Source of book image: http://img1.imagesbn.com/p/9780802120618_p0_v2_s260x420.JPG

(p. C6) Mr. Lapsley also describes John Draper, aka Captain Crunch, who was probably the most celebrated of the phreakers; his nickname derived from the fact that whistles that used to come in Cap’n Crunch cereal boxes happened to generate the key 2600-Hz tone used in long-distance switching. . . .

The phone-phreak netherworld was introduced to a mass audience by the October 1971 issue of Esquire magazine, which included what has to be (at least indirectly) one of the most influential articles ever written: Ron Rosenbaum’s “Secrets of the Little Blue Box.” Not only did it turn phreakers into folk heroes, but it inspired two young men, Steve Wozniak (who provided the foreword for this book) and Steve Jobs, to construct and sell blue boxes. Going door to door in Berkeley dorms, they managed to sell several dozen at $170 each. The “two Steves” savored this mix of clever engineering and entrepreneurial hustle: As Mr. Lapsley quotes Jobs saying: “If we hadn’t made blue boxes, there would have been no Apple.” (Mr. Rosenbaum’s article also put the “phreak” into “phone phreak.”)
. . .: By the 1980s, computerized phone systems and fiber-optic cables rendered many of the old phreaking modes obsolete. In addition, I can’t help suspecting that the breakup of AT&T in 1984–the result of an antitrust lawsuit filed by the federal government–deeply discouraged the hard-core phreaks. Surreptitiously penetrating one of the shriveled new regional phone companies must have seemed a paltry caper compared with taking on mighty, majestic AT&T.
. . .
I must, however, take issue with one of Mr. Lapsley’s conclusions. In reflecting on the phreaks’ legacy, he writes: “The phone phreaks taught us that there is a societal benefit to tolerating, perhaps even nurturing (in the words of Apple) the crazy ones–the misfits, the rebels, the troublemakers.” Is that truly what they taught us? . . .
Wilt Chamberlain supposedly once said that “nobody roots for Goliath.” Perhaps. But the lesson to be learned from those waging guerrilla war against giants like the phone company and the Internet is that sophomoric savants who tamper with society’s indispensable systems ultimately harm all too many innocent people.

Knowledge Economy Migrating to Intangible Goods and Services

(p. 67) Our present economic migration from a material-based industry to a knowledge economy of intangible goods (such as software, design, and media products) is just the latest in a steady move toward the immaterial. (Not that material processing has let up, just that intangible processing is now more economically valuable.) Richard Fisher, president of the Federal Reserve Bank of Dallas, says, “Data from nearly all parts of the world show us that consumers tend to spend relatively less on goods and more on services as their incomes rise. . . . Once people have met their basic needs, they tend to want medical care, transportation and communication, information, recreation, entertainment, financial and legal advice, and the like.” The disembodiment of value (more value, less mass) is a steady trend in the technium. In six years the average weight per dollar of U.S. exports (the most valuable things the U.S. produces) (p. 68) dropped by half. Today, 40 percent of U.S. exports are services (intangibles) rather than manufactured goods (atoms). We are steadily substituting intangible design, flexibility, innovation, and smartness for rigid, heavy atoms. In a very real sense our entry into a service- and idea-based economy is a continuation of a trend that began at the big bang.

You Can Buy a New Flint Knife or Stone Ax

(p. 55) Let’s take the oldest technology of all: a flint knife or stone ax. Well, it turns out you can buy a brand-new flint knife, flaked by hand and carefully attached to an antler-horn handle by tightly wound leather straps. In every respect it is precisely the same technology as a flint knife made 30,000 years ago. It’s yours for fifty dollars, available from more than one website. In the highlands of New Guinea, tribesmen were making stone axes for their own use until the 1960s. They still make stone axes the same way for tourists now. And stone-ax aficionados study them. There is an unbroken chain of knowledge that has kept this Stone Age technology alive. Today, in the United States alone, there are 5,000 amateurs who knap fresh arrowhead points by hand. They meet on weekends, exchange tips in flint-knapping clubs, and sell their points to souvenir brokers. John Whittaker, a professional archaeologist and flint knapper himself, has studied these amateurs and estimates that they produce over one million brand-new spear and arrow points per year. These new points are indistinguishable, even to experts like Whittaker, from authentic ancient ones.
