In Memoriam: 9 Tech Titans Who Died in 2012

"We made machines for the masses," said Jack Tramiel, the founder of the company that gave the world the Commodore 64. Then he nodded to the man sitting beside him, Apple co-founder Steve Wozniak. "They made machines for the classes."

The year was 2007, and Tramiel was on stage at the Computer History Museum in Mountain View, California, celebrating the 25th anniversary of the Commodore 64, a machine that debuted in August 1982 with a price tag of $595 and was soon selling for a mere $199. That made it several hundred dollars cheaper than the Apple II offered by Wozniak and fellow Apple man Steve Jobs — not to mention the IBM PC — and according to Tramiel, Commodore sold nearly half a million machines a month before he left the company in 1984.

All told, Tramiel said that night, somewhere between 22 million and 30 million Commodore 64s were sold, which likely makes it the best-selling home computer of all time. "We sold half that many," said ex-IBM exec William Love, referring to the original IBM PC.

Tramiel passed away this past April at the age of 83, and though he may not have been a household name, the Commodore 64 certainly was.

He was just one of several tech titans who died over the past year. None had the name recognition of a Steve Jobs -- who passed in 2011 -- but they may have moved our world in bigger ways. Among those that passed in 2012 are the IBMer who invented the bar code and the Zenith engineer who devised the first wireless TV remote -- not to mention one of the physicist who helped built the atom bomb dropped on Nagasaki. Click on the images above to remember them all.

Jack Tramiel was born to a Jewish family in Poland in 1928, and during the war, he was sent to Auschwitz, before he was moved with his father to a labor camp in Germany. He was freed in 1945 and emigrated to the States two years later, and in the mid-1950's, he founded a business called Commodore.

At first, it dealt in typewriters, but then it moved to adding machines, calculators, and, yes, home computers. After he was forced out of Commodore in 1984, Tramiel bought the consumer division of game outfit Atari and reformed it as Atari Corporation, which he ran until the end of the decade.

Well: Exercise and the Ever-Smarter Human Brain

Anyone whose resolve to exercise in 2013 is a bit shaky might want to consider an emerging scientific view of human evolution. It suggests that we are clever today in part because a million years ago, we could outrun and outwalk most other mammals over long distances. Our brains were shaped and sharpened by movement, the idea goes, and we continue to require regular physical activity in order for our brains to function optimally.

Phys Ed

Gretchen Reynolds on the science of fitness.

The role of physical endurance in shaping humankind has intrigued anthropologists and gripped the popular imagination for some time. In 2004, the evolutionary biologists Daniel E. Lieberman of Harvard and Dennis M. Bramble of the University of Utah published a seminal article in the journal Nature titled “Endurance Running and the Evolution of Homo,” in which they posited that our bipedal ancestors survived by becoming endurance athletes, able to bring down swifter prey through sheer doggedness, jogging and plodding along behind them until the animals dropped.

Endurance produced meals, which provided energy for mating, which meant that adept early joggers passed along their genes. In this way, natural selection drove early humans to become even more athletic, Dr. Lieberman and other scientists have written, their bodies developing longer legs, shorter toes, less hair and complicated inner-ear mechanisms to maintain balance and stability during upright ambulation. Movement shaped the human body.

But simultaneously, in a development that until recently many scientists viewed as unrelated, humans were becoming smarter. Their brains were increasing rapidly in size.

Today, humans have a brain that is about three times larger than would be expected, anthropologists say, given our species’ body size in comparison with that of other mammals.

To explain those outsized brains, evolutionary scientists have pointed to such occurrences as meat eating and, perhaps most determinatively, our early ancestors’ need for social interaction. Early humans had to plan and execute hunts as a group, which required complicated thinking patterns and, it’s been thought, rewarded the social and brainy with evolutionary success. According to that hypothesis, the evolution of the brain was driven by the need to think.

But now some scientists are suggesting that physical activity also played a critical role in making our brains larger.

To reach that conclusion, anthropologists began by looking at existing data about brain size and endurance capacity in a variety of mammals, including dogs, guinea pigs, foxes, mice, wolves, rats, civet cats, antelope, mongooses, goats, sheep and elands. They found a notable pattern. Species like dogs and rats that had a high innate endurance capacity, which presumably had evolved over millenniums, also had large brain volumes relative to their body size.

The researchers also looked at recent experiments in which mice and rats were systematically bred to be marathon runners. Lab animals that willingly put in the most miles on running wheels were interbred, resulting in the creation of a line of lab animals that excelled at running.

Interestingly, after multiple generations, these animals began to develop innately high levels of substances that promote tissue growth and health, including a protein called brain-derived neurotrophic factor, or BDNF. These substances are important for endurance performance. They also are known to drive brain growth.

What all of this means, says David A. Raichlen, an anthropologist at the University of Arizona and an author of a new article about the evolution of human brains appearing in the January issue of Proceedings of the Royal Society B, is that physical activity may have helped to make early humans smarter.

“We think that what happened” in our early hunter-gatherer ancestors, he says, is that the more athletic and active survived and, as with the lab mice, passed along physiological characteristics that improved their endurance, including elevated levels of BDNF. Eventually, these early athletes had enough BDNF coursing through their bodies that some could migrate from the muscles to the brain, where it nudged the growth of brain tissue.

Those particular early humans then applied their growing ability to think and reason toward better tracking prey, becoming the best-fed and most successful from an evolutionary standpoint. Being in motion made them smarter, and being smarter now allowed them to move more efficiently.

And out of all of this came, eventually, an ability to understand higher math and invent iPads. But that was some time later.

The broad point of this new notion is that if physical activity helped to mold the structure of our brains, then it most likely remains essential to brain health today, says John D. Polk, an associate professor of anthropology at the University of Illinois at Urbana-Champaign, and co-author, with Dr. Raichlen, of the new article.

And there is scientific support for that idea. Recent studies have shown, he says, that “regular exercise, even walking,” leads to more robust mental abilities, “beginning in childhood and continuing into old age.”

Of course, the hypothesis that jogging after prey helped to drive human brain evolution is just a hypothesis, Dr. Raichlen says, and almost unprovable.

But it is compelling, says Harvard’s Dr. Lieberman, who has worked with the authors of the new article. “I fundamentally agree that there is a deep evolutionary basis for the relationship between a healthy body and a healthy mind,” he says, a relationship that makes the term “jogging your memory” more literal than most of us might have expected and provides a powerful incentive to be active in 2013.

Chinese Regulator’s Family Profited From Stake in Insurer

The New York Times

The Ping An International Finance Center, being built in Shenzhen. Ping An is among the world’s biggest financial institutions.

SHANGHAI — Relatives of a top Chinese regulator profited enormously from the purchase of shares in a once-struggling insurance company that is now one of China’s biggest financial powerhouses, according to interviews and a review of regulatory filings.

The regulator, Dai Xianglong, was the head of China’s central bank and also had oversight of the insurance industry in 2002, when a company his relatives helped control bought a big stake in Ping An Insurance that years later came to be worth billions of dollars. The insurer was drawing new investors ahead of a public stock offering after averting insolvency a few years earlier.

With growing attention on the wealth amassed by families of the politically powerful in China, the investments of Mr. Dai’s relatives illustrate that the riches extend beyond the families of the political elites to the families of regulators with control of the country’s most important business and financial levers. Mr. Dai, an economist, has since left his post with the central bank and now manages the country’s $150 billion social security fund, one of the world’s biggest investment funds.

How much the relatives made in the deal is not known, but analysts say the activity raises further doubts about whether the capital markets are sufficiently regulated in China.

Nicholas C. Howson, an expert in Chinese securities law at the University of Michigan Law School, said: “While not per se illegal or even evidence of corruption, these transactions feed into a problematic perception that is widespread in the P.R.C.: the relatives of China’s highest officials are given privileged access to pre-I.P.O. properties.” He was using the abbreviation for China’s official name, the People’s Republic of China.

The company that bought the Ping An stake was controlled by a group of investment firms, including two set up by Mr. Dai’s son-in-law, Che Feng, as well as other firms associated with Mr. Che’s relatives and business associates, the regulatory filings show.

The company, Dinghe Venture Capital, got the shares for an extremely good price, the records show, paying a small fraction of what a large British bank had paid per share just two months earlier. The company paid $55 million for its Ping An shares on Dec. 26, 2002. By 2007, the last time the value of the investment was made public, the shares were worth $3.1 billion.

In its investigation, The New York Times found no indication that Mr. Dai had been aware of his relatives’ activities, or that any law had been broken. But the relatives appeared to have made a fortune by investing in financial services companies over which Mr. Dai had regulatory authority.

In another instance, in November 2002, Dinghe acquired a big stake in Haitong Securities, a brokerage firm that also fell under Mr. Dai’s jurisdiction, according to the brokerage firm’s Shanghai prospectus.

By 2007, just after Haitong’s public listing in Shanghai, those shares were worth about $1 billion, according to public filings. Later, between 2007 and 2010, Mr. Dai’s wife, Ke Yongzhen, was chairwoman on Haitong’s board of supervisors.

A spokesman for Mr. Dai and the National Social Security Fund did not return phone calls seeking comment. A spokeswoman for Mr. Che, the son-in-law, denied by e-mail that he had ever held a stake in Ping An. The spokeswoman said another businessman had bought the Ping An shares and then, facing financial difficulties, sold them to a group that included Mr. Che’s friends and relatives, but not Mr. Che.

The businessman “could not afford what he has created, so he had to sell his shares all at once,” the spokeswoman, Jenny Lau, wrote in an e-mail.

The corporate records reviewed by The Times, however, show that Mr. Che, his relatives and longtime business associates set up a complex web of companies that effectively gave him and the others control of Dinghe Venture Capital, which made the investments in Ping An and Haitong Securities. The records show that one of the companies later nominated Mr. Che to serve on the Ping An board of supervisors. His term ran from 2006 to 2009.

The Times reported last month that another investment company had also bought shares in Ping An Insurance at an unusually low price on the same day in 2002 as Dinghe Venture Capital. That company, Tianjin Taihong, was later partly controlled by relatives of Prime Minister Wen Jiabao, then serving as vice premier with oversight of China’s financial institutions. In late 2007, the shares Taihong bought in Ping An were valued at $3.7 billion.

The investments by Dinghe and Taihong are significant in part because by late 2002, Beijing regulators had granted Ping An an unusual waiver to rules that would have forced the insurer to sell off some divisions. Throughout the late 1990s, the company was fighting rules that would have required a breakup, a move that Ping An executives worried could lead to bankruptcy.

Obama blames GOP for 'fiscal cliff' brinksmanship

WASHINGTON -- President Obama blamed Republican leaders for the latest round of brinkmanship in Washington and said it was now up to lawmakers to find a way back from the so-called fiscal cliff.

In an interview with NBC’s “Meet the Press” aired Sunday, Obama said he had reached out to Republicans for weeks, but their refusal to raise taxes had blocked progress.

“They have had trouble saying yes to a number of repeated offers,” Obama said. In Friday’s meeting with congressional leaders at the White House, “I suggested to them if they can't do a comprehensive package of smart deficit reductions, let's at minimum make sure that people's taxes don't go up and that 2 million people don't lose their unemployment insurance.

“And I was modestly optimistic yesterday,” he added in the interview taped Saturday, referring to the aftermath of that meeting, “but we don't yet see an agreement. And now the pressure's on Congress to produce.”

PHOTOS: Notable moments of the 2012 presidential election

Senate leaders and their aides spent Saturday working on a deal that would protect most taxpayers from seeing their incomes taxes rise Jan. 1. The deal may also set new estate tax rates, prevent an expansion of the alternative minimum tax and extend unemployment insurance.

If the effort is successful, a final proposal is expected later Sunday, when senators are set to meet in party caucuses.

A spokesman for Senate Minority Leader Mitch McConnell responded to the president's criticism:

"While the president was taping those discordant remarks yesterday, Sen. McConnell was in the office working to bring Republicans and Democrats together on a solution," Don Stewart said. "Discussions continue today."

In the interview, Obama said he expected an “adverse reaction in the markets” and depressed consumer spending if lawmakers allow the tax increase to take effect as scheduled -- and he tried to lay the blame on Republicans. Economists have suggested the combination of the tax increases, along with nearly $65 billion in spending cuts, could knock the economy back into a recession.

Obama did not offer a clear strategy for avoiding those spending cuts, which Congress and the president agreed to in 2011 as a way to force themselves to act on a larger deficit reduction deal. That deal has remained elusive, and Obama said in the interview that Republicans have had trouble saying yes to his offers.

QUIZ: How much do you know about the fiscal cliff?

Pressed by host David Gregory on why that is, Obama answered:

“That's something you're probably going to have to ask them, because, David, you follow this stuff pretty carefully. The offers that I’ve made to them have been so fair that a lot of Democrats get mad at me. I mean, I offered to make some significant changes to our entitlement programs in order to reduce the deficit,” he said, referring specifically to a change in the way Social Security cost of living increases are calculated, which many liberal groups opposed.

“They say that their biggest priority is making sure that we deal with the deficit in a serious way, but the way they're behaving is that their only priority is making sure that tax breaks for the wealthiest Americans are protected. That seems to be their only overriding, unifying theme.”

Obama has tried to frame the debate as a battle over taxes. One Republican acknowledged Sunday that the president appears poised to win the political battle on that front. If lawmakers agree on allowing taxes to rise on top earners, “it will accomplish a political victory for the president,” said Sen. Lindsey Graham of South Carolina

“Hats off to the president. He stood his ground; he’s going to get tax rate increases … on upper income Americans. And the sad news for the country is we’ve accomplished very little in terms of not becoming Greece or getting out of debt.… Hats off to the president -- he won.”

[For the Record, 8:05 a.m. PST  Dec. 30: This post has been updated to include reactions to Obama's comments from McConnell's office.]

Hot spots draw believers, but not doomsday

As the sun rose from time zone to time zone across the world on Friday, there was still no sign of the world’s end — but that didn’t stop those convinced that a 5,125-year Mayan calendar predicts the apocalypse from gathering at some of the world’s purported survival hot spots.

Many of the esoterically inclined expected a new age of consciousness — others wanted a party. But, in some places said to offer salvation from the end, fewer people showed up than officials had predicted — much to the disappointment of vendors hoping to sell souvenirs.

Here are some key places being marked by the fascination over doomsday rumors:

MEXICO

In an area of Mexico that was once the ancient Mayan heartland, spiritualists gathered in the darkness before dawn on Friday to prepare white clothes, drums, conch shells and incense. They believed the sunrise would herald the birth of a new and better age as a vast cycle in the Mayan calendar comes to an end.

Many people who came to Yucatan for the occasion were already calling it “a new sun” and “a new era.”

FRANCE

According to one rumor, a rocky mountain in the French Pyrenees will be the sole place on Earth to escape destruction. A giant UFO and aliens are said to be waiting under the mountain, ready to burst through and spirit those nearby to safety. But there is bad news for those seeking salvation: French gendarmes, some on horseback, blocked outsiders from reaching the Bugarach peak and its village of some 200 people.

Eric Freysselinard, head of local government, said the security forces had “partially stopped the new age enthusiasts as well as curious people from coming to the area.”

Meanwhile, some Bugarach residents dressed up like aliens, with tinfoil costumes and funnels and fake antenna on their heads, strolling around their village Friday to make light of the rumored UFO prophecy.

RUSSIA

Doomsday rumors have prompted some people across Russia to stock up on candles, water, canned foods and other non-perishable foods. The apocalypse has proven a good business, with some shops selling survival aid packages that include soap and vodka.

In Moscow, salvation has also been promised in the underground bunker for the former Soviet dictator Josef Stalin — with a 50 percent refund if nothing happens. An underground stay was originally priced at 50,000 rubles ($ 1,625) but dropped to 15,000 ($ 490) a week ahead of the feared end.

The bunker, located 65 meters (210 feet) below ground, was designed to withstand a nuclear attack. Now home to a small museum, it has an independent electricity supply, water and food — but no more room, because the museum has already sold out all 1,000 tickets.

BRITAIN

Hundreds of people have converged on Stonehenge for an “End of the World” party that coincides with the Winter Solstice.

Arthur Uther Pendragon, Britain’s best-known druid, said he was anticipating a much larger crowd than usual at Stonehenge this year. But he doesn’t agree that the world is ending, noting that he and fellow druids believe that things happen in cycles.

“We’re looking at it more as a new beginning than an end,” he said. “We’re looking at new hope.”

Meanwhile, end-of-days parties will be held across London on Friday. One event billed as a “last supper club” is offering a three-course meal served inside an “ark.”

SERBIA

Some Serbs are saying to forget that sacred mountain in the French Pyrenees. The place to be Friday is Mount Rtanj, a pyramid-shaped peak in Serbia already drawing cultists.

According to legend, the mountain once swallowed an evil sorcerer who will be released on doomsday in a ball of fire that will hit the mountain top. The inside of the mountain will then open up, becoming a safe place to hide as the sorcerer goes on to destroy the rest of the world. In the meantime, some old coal mine shafts have been opened up as safe rooms.

On Friday a New Age group called “The Spirit of Rtanj” was holding a conference there. Participants, however, said they expect not the end of time but the start of a new time cycle. Locals turned out to sell brandy and herbs.

“There will be no tragedy, no doomsday,” said resident Dalibor Jovic. “It was supposed to happen at 12:12 and I think that time has passed. So, we can now go on with our lives and be happy to be alive.”

TURKEY

A small Turkish village known for its wines, Sirince, has also been touted as the only place after Bugarach that would escape the world’s end. But on Friday journalists and security officials outnumbered cultists. This outcome disappointed local business people who had prepared a range of doomsday products to sell, including a specially labeled Doomsday wine and Turkish delight candy whose “best before” date was Dec. 21, 2012. One restaurant prepared a special “last meal” menu that included a “heaven kebab” and “forbidden fruit dessert.”

ITALY

Another spot said to be spared: Cisternino, a beautiful small town in southern Italy in an area of trulli, traditional dry stone huts with conical roofs. The notion that Cisternino could be a safe haven at world’s end derives from an Indian guru, Babaji, who said “Cisternino will become an island” at world’s end. His followers built a community in Cisternino centered on an ashram built in 1979. Hotel bookings are up this weekend.

Mayor Donato Baccaro told the AP that the beauty of the place has inspired many foreigners to live there. “This confirms that this place has a special energy,” he said.

CHINA

A fringe Christian group has been spreading rumors about the world’s impending end, prompting Chinese authorities to detain more than 500 people this week and seize leaflets, video discs, books and other material.

Those detained are reported to be members of the group Almighty God, also called Eastern Lightning, which preaches that Jesus has reappeared as a woman in central China. Authorities in the province of Qinghai say they are waging a “severe crackdown” on the group, accusing it of attacking the Communist Party and the government.

U.S.

Dozens of Michigan schools canceled classes for thousands of students to cool off rumored threats of violence and problems related to doomsday. The fears were exacerbated by the recent shooting at a Connecticut elementary school, which “changed all of us,” the school system in Genesee County said. “Canceling school is the right thing to do.”

Associated Press writers Florent Bajrami in Bugarach, France; Mansur Mirovalev in Moscow; Peppino Ciraci in Cisternino, Italy; Suzan Fraser in Ankara, Turkey; Paisley Dodds in London; and Dejan Mladenovic in Mount Rtanj, Serbia, contributed to this report.

Suspect in homeless woman's burning is mentally ill, police say

By Ashley Powers, Bob Pool and Richard Winton

December 28, 2012, 8:36 a.m.

A man arrested on suspicion of setting a homeless woman on fire while she slept on a Van Nuys bus bench is believed to be mentally ill, police said.

There was no rhyme or reason for Thursday's attack that left the woman known as Flo in critical condition after she was allegedly doused with rubbing alcohol and set on fire by Dennis Petillo, 24, said Los Angeles Police Deputy Chief Kirk Albanese.

“There was no incident or dispute or clear motivation for this horrific attack. He did not know his victim. It defies explanation,” Albanese said. “He is not of sound mind.... The motive is mental illness.”

Police have not released the woman's name, but residents said she was Flo Parker. She was also known as Violet: a 5-foot-tall woman with dirty blond hair and a time-worn face that made her look older than her 67 years. She remained in critical condition Friday.

“This is a hate crime as far as I’m concerned. All this woman did was try to sit out here and get warm,” said Barbara Weiss, 57, who works for a company that provides transportation to the handicapped.

In Thursday’s early hours, witness Erickson Ipina told reporters, he watched in horror as the attack unfolded. A man walked out of the Walgreens with what appeared to be rubbing alcohol, he said.

“He just poured it all over the old lady,” Ipina said. “Then he threw the match on her and started running.”

Ipina said he gave chase. “Hey, stop right there!” he said he yelled. “Stop right there!” But the man kept running.

“I pulled out my cellphone and called 911 and then he just turned back on me and pulled out a knife,” said Ipina, whose account was confirmed by the LAPD.

Police arrested Petillo on suspicion of attempted murder. Since 2008, he has pleaded guilty twice to charges related to vehicle theft. The second time, he was sentenced to two years in prison.

Bluetooth Tracking Can Predict the Length of Your Commute Hell

Bluetooth is good for more than silly headsets and wireless speakers. The city of Calgary, Alberta, is using the technology to give drivers real-time information about travel time during their commute.

The Travel Time Information System along Calgary’s Deerfoot Trail anonymously collects Bluetooth signals from mobile phones, headsets and other devices to estimate travel times and gauge congestion. Travel times are then displayed on electronic signs along the roadway.

All Bluetooth devices contain a unique ID code. According city officials, the Travel Time Information System encrypts and monitors Bluetooth signals without tracking other information and gathers MAC addresses only. The system reads the Bluetooth codes at 15 sensor points along Deerfoot Trail.

A central server at the city’s traffic management center collects the data from 15 sensors and sends traffic info to seven roadside displays. Algorithms sift out signals from drivers, pedestrians and other sources near, but not on, Deerfoot Trail to minimize erroneous data.

The city found the system consistently accurate during a trial in 2010, and it has grown more precise as more people use Bluetooth devices. “Drivers will be able to make informed route planning choices in real time,” Gord Elenko, manager of Calgary’s road traffic division, told Phsy.org. “We believe it will eventually help reduce congestion and decrease driver frustration.”

The system operates during peak travel times — from 6:30 a.m. until 6:30 p.m. — Monday through Friday. After assessing the reliability of the system by monitoring travel times during rush hour, Calgary plans to extend the hours of operation.

The city spent about $400,000 on the system and plans to expand it to include other areas as funding becomes available. It hopes to eventually install 26 Bluetooth detection systems on major commuter routes citywide.
