(p. D3) Human ancestors were using stone-tipped spears to hunt 500,000 years ago, 200,000 years earlier than previously thought.

A new study reports that the stone tips, found in South Africa, were probably once attached to wooden spears and then hurled at animals by hominins of the species Homo heidelbergensis.
Homo heidelbergensis was the last common ancestor of modern humans and Neanderthals, said Jayne Wilkins, an anthropologist at the University of Toronto and the study’s first author. The spears “suggest that the behavioral complexity of these early humans was greater than expected,” she said. Creating a stone-tipped spear would have required attaching stone to wood, handling multiple types of material at once, planning and goal-oriented behavior.

Apple “Finding a Way to Leapfrog Over Its Competitors”

Isaacson says Jobs wanted two refinements in the iMac. One was new colors. The other is discussed below.
I am not sure what to make of this episode. Is Isaacson suggesting that it was good for Apple that Jobs made a mistake on the type of CD hardware to put in the iMac? That this added constraint “would then force Apple to be imaginative and bold”?
Or is the moral that good people who make a lot of quick decisions, make mistakes, sometimes big mistakes, and that Jobs found a way to bounce back from this one?

(p. 356) There was one other important refinement that Jobs wanted for the iMac: getting rid of that detested CD tray. “I’d seen a slot-load drive on a very high-end Sony stereo,” he said, “so I went to the drive manufacturers and got them to do a slot-load drive for us for the version of the iMac we did nine months later.” Rubinstein tried to argue him out of the change. He predicted that new drives would come along that could burn music onto CDs rather than merely play them, and they would be available in tray form before they were made to work in slots. “If you go to slots, you will always be behind on the technology,” Rubinstein argued.

“I don’t care, that’s what I want,” Jobs snapped back. They were having lunch at a sushi bar in San Francisco, and Jobs insisted that they continue the conversation over a walk. “I want you to do the slot-load drive for me as a personal favor,” Jobs asked. Rubinstein agreed, of course, but he turned out to be right. Panasonic came out with a CD drive that could rip and burn music, and it was available first for computers that had old-fashioned tray loaders. The effects of this (p. 357) would ripple over the next few years: It would cause Apple to be slow in catering to users who wanted to rip and burn their own music, but that would then force
Apple to be imaginative and bold in finding a way to leapfrog over its competitors when Jobs finally realized that he had to get into the music market.

UnCollege Seeks “to Open People’s Minds to a Different Set of Opportunities”

“Dale J. Stephens, who founded UnCollege.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. 1) BENJAMIN GOERING does not look like Facebook’s Mark Zuckerberg, talk like him or inspire the same controversy. But he does apparently think like him.

Two years ago, Mr. Goering was a sophomore at the University of Kansas, studying computer science and philosophy and feeling frustrated in crowded lecture halls where the professors did not even know his name.
“I wanted to make Web experiences,” said Mr. Goering, now 22, and create “tools that make the lives of others better.”
So in the spring of 2010, Mr. Goering took the same leap as Mr. Zuckerberg: he dropped out of college and moved to San Francisco to make his mark. He got a job as a software engineer at a social-software company, Livefyre, run by a college dropout, where the chief technology officer at the time and a lead engineer were also dropouts. None were sheepish about their lack of a diploma. Rather, they were proud of their real-life lessons on the job.
“Education isn’t a four-year program,” Mr. Goering said. “It’s a mind-set.”
The idea that a college diploma is an all-but-mandatory ticket to a successful career is showing fissures. Feeling squeezed by a sagging job market and mounting student debt, a groundswell of university-age heretics are pledging allegiance to new groups like UnCollege, dedicated (p. 16) to “hacking” higher education. Inspired by billionaire role models, and empowered by online college courses, they consider themselves a D.I.Y. vanguard, committed to changing the perception of dropping out from a personal failure to a sensible option, at least for a certain breed of risk-embracing maverick.
Risky? Perhaps. But it worked for the founders of Twitter, Tumblr and a little company known as Apple.
When Mr. Goering was wrestling with his decision, he woke up every morning to a ringtone mash-up that blended electronic tones with snippets of Steve Jobs’s 2005 commencement address at Stanford University, in which he advised, “love what you do,” “don’t settle.” Mr. Goering took that as a sign.
“It’s inspiring that his dropping out basically had no effect, positive or negative, on the work and company and values he could create,” he said of the late Apple co-founder.
In that oft-quoted address, Mr. Jobs called his decision to drop out of Reed College “one of the best decisions I ever made.” Mr. Jobs’s “think different” approach to education (backpacking through India, dining with Hare Krishnas) is portrayed in countless hagiographies as evidence of his iconoclastic genius.
. . .
. . . Dale J. Stephens, [is] the founder of a group called UnCollege that champions “more meaningful” alternatives to college. . . .
. . .
UnCollege advocates a D.I.Y. approach to higher education and spreads the message through informational “hackademic camps.” “Hacking,” in the group’s parlance, can involve any manner of self-directed learning: travel, volunteer work, organizing collaborative learning groups with friends. Students who want to avoid $200,000 in student-loan debt might consider enrolling in a technology boot camp, where you can learn to write code in 8 to 10 weeks for about $10,000, Mr. Stephens said.
THEY can also nourish their minds from a growing menu of Internet classrooms, including the massive open online courses, or MOOCs, which stream classes from elite universities like Princeton. This guerrilla approach hits home with young people who came of age seeking out valuable content free on Napster and BitTorrent.
Mr. Stephens, a dropout from Hendrix College in Arkansas (he later earned a Thiel Fellowship), started UnCollege less than two years ago, and already its Web site attracts 20,000 unique visitors a month. “I get on scale of 10 to 15 e-mails a day from people who say something along lines of, ‘I thought I was the only one out there who thought about education like this, I don’t feel crazy anymore,’ ” he said.
. . .
The goal is not to foment for a mass exodus from the ivy halls, Mr. Stephens said, but to open people’s minds to a different set of opportunities.

When Professors “Are Fearful, Hesitant, and Foolish” and When They “Screech, Snarl, and Spit”

(p. 243) “It is hardly possible to take very seriously any of the professoriate all of the time or most of them most of the time. They commonly are fearful, hesitant, and foolish when confronted by complex real issues and aggressive enemies, but they tend to screech, snarl, and spit when they perceive their territory, reputation, and perquisites to be threatened. They can pose as being valiant and principled, but they are inclined to disperse and camouflage themselves upon hearing the first volleys of significant battle.”

“A Fairy Tale About a Lonely Candle that Wants to Be Lighted”

“A newly found manuscript of a fairy tale by Hans Christian Andersen, which has been located in Odense, is pictured in the State Archives in Copenhagen, Denmark, Wednesday, Dec. 12, 2012. The story of ‘The Tallow Candle’ might have been written about 1823, when he was 18 year old.” Source of caption and photo: http://www.ctvnews.ca/entertainment/new-found-tale-of-a-lonely-candle-could-be-early-work-of-hc-andersen-1.1077533#ixzz2GmTQNcFvhttp://www.ctvnews.ca/polopoly_fs/1.1077539!/

(p. C2) A fairy tale about a lonely candle that wants to be lighted had been languishing in a box in Denmark’s National Archives for many years. In October it was discovered by a retired historian, who now believes it is one of the first fairy tales ever written by Hans Christian Andersen.
. . .
The six-page manuscript, called “Tallow Candle,” is dedicated to a vicar’s widow named Bunkeflod who lived across the street from Andersen’s home. Ejnar Stig Askgaard, a Hans Christian Andersen expert, said the work was probably one of Andersen’s earliest.

“Think Profit”

(p. 339) At the January 1998 San Francisco Macworld, Jobs took the stage where Amelio had bombed a year earlier. He sported a full beard and a leather jacket as he touted the new product strategy. And for the first time he ended the presentation with a phrase that he would make his signature coda: “Oh, and one more thing . . .” This time the “one more thing” was “Think Profit.” When he said those words, the crowd erupted in applause. After two years of staggering losses, Apple had enjoyed a profitable quarter, making $45 million. For the full fiscal year of 1998, it would turn in a $309 million profit. Jobs was back, and so was Apple.

Government Job Protection Regulations Reduce Youth Jobs

Source of graph: online version of the WSJ article quoted and cited below.

(p. A7) Socialist President François Hollande has come up with a plan to ease the problem: give €4,000 ($5,276) a year for three years to small companies that hire a young person on a permanent contract while committing to keep an employee age 57 or over.
. . .
The French government hopes as many as half a million youths will find permanent jobs over the next five years due to the measure, which could cost the government about €1 billion a year when it is in place.
Economists say the number of real new jobs is likely to be much lower because the government will be subsidizing jobs that would have been created anyway. Only around 100,000 new jobs will be created, according to OFCE, an economic-research think tank in Paris.
French companies say they are reluctant to hire young people on permanent contracts because it gives employees a level of protection the companies say they can’t afford to grant–even if they get the subsidy proposed by Mr. Hollande.
“It’s great to have €4,000, but if the new recruit isn’t good, we don’t know how long we’ll be stuck with them,” said Philippe Lehmann, who runs Lehmann Sarl, a mechanical-parts factory in Molsheim, eastern France that employs seven people.

How Chavez Punished Those Who Opposed Him

(p. 196) In 2004, the Hugo Chávez regime in Venezuela distributed the list of several million voters who had attempted to remove him from office throughout the government bureaucracy, allegedly to identify and punish these voters. We match the list of petition signers distributed by the government to household survey respondents to measure the economic effects of being identified as a Chávez political opponent. We find that voters who were identified as Chávez opponents experienced a 5 percent drop in earnings and a 1.3 percentage point drop in employment rates after the voter list was released.

“People Said He Was a Fraud, But He Turned Out to Be Right”

“Willis Whitfield with a mobile clean room in the 1960s.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. B16) Half a century ago, as a rapidly changing world sought increasingly smaller mechanical and electrical components and more sanitary hospital conditions, one of the biggest obstacles to progress was air, and the dust and germs it contains.
. . .
Then, in 1962, Willis Whitfield invented the clean room.
“People said he was a fraud,” recalled Gilbert V. Herrera, the director of microsystems science and technology at Sandia National Laboratories in Albuquerque. “But he turned out to be right.”
. . .
His clean rooms blew air in from the ceiling and sucked it out from the floor. Filters scrubbed the air before it entered the room. Gravity helped particles exit. It might not seem like a complicated concept, but no one had tried it before. The process could completely replace the air in the room 10 times a minute.
Particle detectors in Mr. Whitfield’s clean rooms started showing numbers so low — a thousand times lower than other methods — that some people did not believe the readings, or Mr. Whitfield. He was questioned so much that he began understating the efficiency of his method to keep from shocking people.
“I think Whitfield’s wrong,” a scientist from Bell Labs finally said at a conference where Mr. Whitfield spoke. “It’s actually 10 times better than he’s saying.”

Jobs Laid Off 3,000 from Apple to Save It from Bankruptcy

(p. 339) In his first year back, Jobs laid off more than three thousand people, which salvaged the company’s balance sheet. For the fiscal year that ended when Jobs became interim CEO in September 1997, Apple lost $1.04 billion. “We were less than ninety days from being insolvent,” he recalled.
