Making a Dirt Dog, Vol. 4: As the Bike Turns

Editor’s note: For those of you joining us late, Peter Rubin’s a roadie making his first foray into mountain biking. He knows nothing — seriously, zero — about that side of cycling, so he’s chronicling his adventures in the hope that others might learn from his inevitable mistakes.

It’s Day 2 at Gene Hamilton’s Better Ride skills camp. After a day in which I spent close to eight hours in a parking lot and about 15 minutes riding on a trail, I can’t say I was all that excited about waking up at 7 on a Saturday for more of the same. But there I was (albeit in a different parking lot). And this time, we were learning how to steer.

No, really.

So here’s what you don’t do on a bike when you want to go around the corner: turn the handlebars. Well, kind of. Under 6 mph or so, that’s really the only way to do it. But once you’re going faster than that, wrenching the wheel in a given direction means you’re about a half-second away from kissing pavement. The front wheel will just keep turning in that direction until it hits a right angle and you fly over the handlebars. Don’t believe me? Try it yourself.

Done?

What happens, you no doubt noticed, is that you didn’t kiss the pavement. Your bike actually swerved in the opposite direction. That’s because your body, purely instinctively, counteracts what your brain thinks you’re trying to do. (Give it up for self-preservation!) All of this is to say that turning the wheel is not how you turn. The thing is, you already know that — at least, your body does. You’ve internalized what’s commonly known as “countersteering,” which essentially means initiating a turn in one direction with the intention of going the opposite direction. But as Hamilton, who founded Better Ride, and coach Dylan Renn pointed out, it’s not so much steering in the opposite direction as it is applying pressure in the opposite direction. That is, if you want to make a sharp left turn, you apply pressure on the left handlebar. That initiates a turn to the right, after which your bike will lean left to compensate, and you can lean into a sharp left turn.

Now, this is no secret among road cyclists and motorcyclists. But the effect on mountain biking is a bit more pronounced because the crux of MTBing is to stay balanced above your bike no matter what. From front to back and left to right, your mass should be centered above your bottom bracket. That means that if your bike is going to be leaning to the left for a sharp left turn, you separate your body from the bike and allow it to lean without leaning along with it. Which leads us, conveniently, to the Better Ride cornering method.

1. Attack position. Always attack position.


2. Look into the turn. Building on the vision drills of Day 1, we learned how to look at the apex of the turn as we initiated cornering, so that we’d be looking well past the turn by the time we were actually mid-corner.


3. Initiate cornering via counterpressure.


4. Separate from the bike by straightening the arm to the inside of the turn, and rotating the outside hand forward over the handlebar just enough so that the outside arm is bent at a 90-degree angle. (If this sounds confusing, see this image from Better Ride’s Facebook Page).

After lunch, we took to the trail (only five hours after the day’s class began!) and climbed through Pearson-Arastradero Preserve to the top of a series of sweeping turns. They weren’t switchbacks — that’s a whole ‘nother set of skills, and one I’d learn on Day 3 — but certainly tight enough that going through them with a good head of steam would press into service all the techniques drilled into me in the parking lot. Dylan stood at the apex of one, Gene at the apex of another, and we took turns bombing down through the turns. And then again. And again. Attack position. Counterpressure. Separate from the bike. And I swear to you, every time I headed down anew, my smile was bigger than the time before.

Lindsay Lohan arrested on assault charge in NYC

NEW YORK (AP) — Actress Lindsay Lohan was arrested Thursday after police said she hit a woman during an argument at a New York City nightclub.

The “Mean Girls” and “Freaky Friday” star was arrested at 4 a.m. and charged with third-degree assault.

She left a police precinct nearly four hours later with a black jacket pulled over her head. She was wearing leggings, a green mini skirt and high-heels, and drove off in a black SUV with a driver and another man who was seen going in and out of the precinct.

She allegedly got into the spat with another woman at Club Avenue, in Manhattan‘s Chelsea section. She struck the woman in face with her hand, police said. The woman did not require medical attention.

Lohan’s publicist did not immediately return a call for comment.

The arrest is Lohan’s latest brush with law enforcement in New York City.

She was involved in a NYPD investigation in September after alleging a man had assaulted her in a New York hotel, but charges against the man were later dropped.

Also in September, the actress was accused of clipping a man with her car outside another Manhattan nightclub, but prosecutors chose not to move ahead with charges.

In October, police were called to her childhood home on Long Island after a report of fight between her and her mother. An investigation revealed “no criminality.”

The actress was also involved in a car accident in California this summer that sent her and an assistant to a hospital, but didn’t result in serious injuries for anyone. The accident remains under investigation.

In May, she was cleared of allegations that she struck a Hollywood nightclub manager with her car.

Lohan remains on informal probation for taking a necklace from a jewelry store without permission last year. That means she doesn’t have to check in with a judge or probation officer but could face a jail term if arrested again.

Her latest film, “Liz & Dick,” in which she portrays screen icon Elizabeth Taylor, premiered on Lifetime on Sunday.

Lohan also recently filmed “The Canyons,” an indie film written by “Less Than Zero” and “American Psycho” author Bret Easton Ellis.

Poll says 6 in 10 Americans back tax hike on income over $250,000

WASHINGTON -- Six in 10 Americans support a tax increase on annual income of more than $250,000, according to a nationwide poll released Wednesday.

Such a hike is the centerpiece of President Obama's efforts to avoid the large automatic tax increases and spending cuts, collectively known as the fiscal cliff, that are coming at the start of next year.

The Washington Post/ABC News poll showed 73% of Democrats and 63% of independents back raising taxes on incomes over $250,000, while just 39% of Republicans support it. 

The poll results show the divide in Washington between Democrats and Republicans over reaching a major deficit-reduction package that would avoid the fiscal cliff. But the findings could boost Obama as he takes his case to the public.

House Speaker John Boehner (R-Ohio) has said he's open to raising additional tax revenue from the wealthy to help close the deficit, but wants to do it by eliminating deductions in the tax code.

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

The Post/ABC poll showed that approach has less support than Obama's, with 44% supporting a reduction in deductions that people can claim on their federal taxes and 49% opposed.

Democratic and independent support for that idea is about the same as the national figure, but only 39% of Republicans back the approach, the poll said.

One area of agreement among Democrats, Republicans and independents is opposition to raising the age for Medicare coverage to 67 years old from 65, with 67% of respondents opposing it.

Sen. Bob Corker (R-Tenn.) has proposed a gradual increase in the eligibility age for Medicare and Social Security as part of a deficit-reduction plan.

Robotic Autobot Transformer Shows Other 3D-Printed Gear Who's Boss

Forget scale models of the Aston Martin DB5 or personalized action figures. This is what 3D printers were meant to do: create real, robotic Transformers.

Or at least a version of a Transformer that would actually fit in your living room.

Brave Robotics developed a 1/12 scale Autobot transformer using a custom 3D printer, and it will be on display at Maker Faire Tokyo next week. Once fully morphed out of its initial automobile form, it takes the shape of a bipedal robot that moves about much like two-legged soccer-playing robots we’ve seen at Robocup and Robogames. This robot also has the ability to shoot some sort of dart from each of its arms.

A fully assembled and programed mini-Autobot, complete with remote control and housed in its own case, will be available for purchase, but a price has not yet been disclosed. Production is limited to 10 units, but you can choose the colors of your Decepticon fighting robot. Once you’ve placed your order, it’ll take about a month to produce.

Check out this Earth-defending, shape-shifting robot in action below.

Rihanna’s “Unapologetic” tops Billboard album chart

LOS ANGELES (Reuters) – R&B singer Rihanna shot straight to the top of the Billboard 200 album chart on Tuesday with her seventh record “Unapologetic,” scoring her first No. 1 album despite mixed reviews.

“Unapologetic,” which topped iTunes charts in 43 countries just hours after its release on November19, sold 238,000 copies according to Billboard, scoring the 24-year-old singer from Barbados her best opening sales week to date.

The album’s lead single “Diamonds” landed at the top of the Billboard Hot 100 chart last week, giving Rihanna her 12th No. 1 single and tying her with Madonna and The Supremes for the fourth-most chart-topping singles in Billboard history.

“Unapologetic” left some critics unsettled by the singer’s harder sound and close-to-home lyrics. One track in particular that had everyone talking is “Nobody’s Business,” Rihanna’s collaboration with ex-boyfriend Chris Brown, who was charged with assaulting her three years ago.

The album has been promoted extensively by Rihanna, who embarked on a seven day tour across seven cities around the world, accompanied by a plane full of fans and journalists.

The full Billboard charts will be released on Wednesday.

The New Old Age Blog: Doctor's Orders? Another Test

It is no longer news that Americans, and older Americans in particular, get more routine screening tests than they need, more than are useful. Prostate tests for men over 75, annual Pap smears for women over 65 and colonoscopies for anyone over 75 — all are overused, large-scale studies have shown.

Now it appears that many older patients are also subjected to too-frequent use of the other kind of testing, diagnostic tests.

The difference, in brief: Screening tests are performed on people who are asymptomatic, who aren’t complaining of a health problem, as a way to detect incipient disease. We have heard for years that it is best to “catch it early” — “it” frequently being cancer — and though that turns out to be only sometimes true, we and our doctors often ignore medical guidelines and ongoing campaigns to limit and target screening tests.

Diagnostic tests, on the other hand, are meant to help doctors evaluate some symptom or problem. “You’re trying to figure out what’s wrong,” explained Gilbert Welch, a veteran researcher at the Dartmouth Institute for Health Policy and Clinical Practice.

For these tests, medical groups and task forces offer many fewer guidelines on who should get them and how often — there is not much evidence to go on — but there is general agreement that they are not intended for routine surveillance.

But a study using a random 5 percent sample of Medicare beneficiaries — nearly 750,000 of them — suggests that often, that is what’s happening.

“It begins to look like some of these tests are being routinely repeated, and it’s worrisome,” said Dr. Welch, lead author of the study just published in The Archives of Internal Medicine. “Some physicians are just doing them every year.”

He is talking about tests like echocardiography, or a sonogram of the heart. More than a quarter of the sample (28.5 percent) underwent this test between 2004 and 2006, and more than half of those patients (55 percent) had a repeat echocardiogram within three years, most commonly within a year of the first.

Other common tests were frequently repeated as well. Of patients who underwent an imaging stress test, using a treadmill or stationery bike (or receiving a drug) to make the heart work harder, nearly 44 percent had a repeat test within three years. So did about half of those undergoing pulmonary function tests and chest tomography, a CAT scan of the chest.

Cytoscopy (a procedure in which a viewing tube is inserted into the bladder) was repeated for about 41 percent of the patients, and endoscopy (a swallowed tube enters the esophagus and stomach) for more than a third.

Is this too much testing? Without evidence of how much it harms or helps patients, it is hard to say — but the researchers were startled by the extent of repetition. “It’s inconceivable that it’s all important,” Dr. Welch said. “Unfortunately, it looks like it’s important for doctors.”

The evidence for that? The study revealed big geographic differences in diagnostic testing. Looking at the country’s 50 largest metropolitan areas, it found that nearly half the sample’s patients in Miami had an echocardiogram between 2004 and 2006, and two thirds of them had another echocardiogram within three years — the highest rate in the nation.

In fact, for the six tests the study included, five were performed and repeated most often in Florida cities: Miami, Jacksonville and Orlando. “They’re heavily populated by physicians and they have a long history of being at the top of the list” of areas that do a lot of medical procedures and hospitalizations, Dr. Welch said.

But in Portland, Ore., where “the physician culture is very different,” only 17.5 percent of patients had an echocardiogram. The places most prone to testing were also the places with high rates of repeat testing. Portland, San Francisco and Sacramento had the lowest rates.

We often don’t think of tests as having a downside, but they do. “This is the way whole cascades can start that are hard to stop,” Dr. Welch said. “The more we subject ourselves, the more likely some abnormality shows up that may require more testing, some of which has unwanted consequences.”

Properly used, of course, diagnostic tests can provide crucial information for sick people. “But used without a good indication, they can stir up a hornet’s nest,” he said. And of course they cost Medicare a bundle.

An accompanying commentary, sounding distinctly exasperated, pointed out that efforts to restrain overtesting and overtreatment have continued for decades. The commentary called it “discouraging to contemplate fresh evidence by Welch et al of our failure to curb waste of health care resources.”

It is hard for laypeople to know when tests make sense, but clearly we need to keep track of those we and our family members have. That way, if the cardiologist suggests another echocardiogram, we can at least ask a few pointed questions:

“My father just had one six months ago. Is it necessary to have another so soon? What information do you hope to gain that you didn’t have last time? Will the results change the way we manage his condition?”

Questions are always a good idea. Especially in Florida.

Ex-NASA Scientist’s Data Fears Come True

In 2007, Robert M. Nelson, an astronomer, and 27 other scientists at the Jet Propulsion Laboratory sued NASA arguing that the space agency’s background checks of employees of government contractors were unnecessarily invasive and violated their privacy rights.

Privacy advocates chimed in as well, contending that the space agency would not be able to protect the confidential details it was collecting.

The scientists took their case all the way to the Supreme Court only to lose last year.

This month, Dr. Nelson opened a letter from NASA telling him of a significant data breach that could potentially expose him to identity theft.

The very thing he and advocates worried about had occurred. A laptop used by an employee at NASA’s headquarters in Washington had been stolen from a car parked on the street on Halloween, the space agency said.

Although the laptop itself was password protected, unencrypted files on the laptop contained personal information on about 10,000 NASA employees — including details like their names, birth dates, Social Security numbers and in some cases, details related to background checks into employees’ personal lives.

Millions of Americans have received similar data breach notices from employers, government agencies, medical centers, banks and retailers. NASA in particular has been subject to “numerous cyberattacks” and computer thefts in recent years, according to a report from the Government Accountability Office, an agency that conducts research for Congress.

Even so, Dr. Nelson, who recently retired from the Jet Propulsion Laboratory, a research facility operated by the California Institute of Technology under a contract with NASA, stands out as a glaring example of security lapses involving personal data, privacy advocates say.

“To the extent that Robert Nelson looks like millions of other people working for firms employed by the federal government, this would seem to be a real problem,” said Marc Rotenberg, the executive director of the Electronic Privacy Information Center, an advocacy group which filed a friend-of-the-court brief for Dr. Nelson in the Supreme Court case.

In a 2009 report titled “NASA Needs to Remedy Vulnerabilities in Key Networks,” the Government Accountability Office noted that the agency had reported 1,120 security incidents in fiscal 2007 and 2008 alone.

It also singled out an incident in 2009 in which a NASA center reported the theft of a laptop containing about 3,000 unencrypted files about arms traffic regulations and wind tunnel tests for a supersonic jet.

“NASA had not installed full-disk encryption on its laptops at all three centers,” the report said. “As a result, sensitive data transmitted through the unclassified network or stored on laptop computers were at an increased risk of being compromised.” Other federal agencies have had similar problems. In 2006, for example, the Department of Veteran’s Affairs reported the theft of an employee laptop and hard drive that contained personal details on about 26.5 million veterans. Last year, the G.A.O. cited the Internal Revenue Service for weaknesses in data control that could “jeopardize the confidentiality, integrity, and availability of financial and sensitive taxpayer information.”

Also last year, the Securities and Exchange Commission warned its employees that their confidential financial information, like brokerage transactions, might have been compromised because an agency contractor had granted data access to a subcontractor without the S.E.C.’s authorization.

In a phone interview, Dr. Nelson, the astronomer, said he planned to hold a news conference on Wednesday morning in which he would ask members of Congress to investigate NASA’s data collection practices and the recent data breach.

Robert Jacobs, a NASA spokesman, said the agency’s data security policy already adequately protected employees and contractors because it required computers to be encrypted before employees took them off agency premises. “We are talking about a computer that should not have left the building in the first place,” Mr. Jacobs said. “The data would have been secure had the employee followed policy.”

The government argued in the case Dr. Nelson filed that a law called the Privacy Act, which governs data collection by federal agencies, provided the scientists with sufficient protection. The case reached the Supreme Court, which upheld government background checks for employees of contractors. The roots of Dr. Nelson’s case against NASA date back to 2004 when the Department of Homeland Security, under a directive signed by President George Bush, required federal agencies to adopt uniform identification credentials for all civil servants and contract employees. As part of the ID card standardization process, the department recommended agencies institute background checks.

Several years later, when NASA announced it intended to start doing background checks at the Jet Propulsion Laboratory, Dr. Nelson and other scientists there objected.

Those security checks could have included inquiries into medical treatment, counseling for drug use, or any “adverse” information about employees such as sexual activity, or participation in protests, said Dan Stormer, a lawyer representing Dr. Nelson.

But Dr. Nelson and other long-term employees of the lab challenged the legality of those checks, arguing that they violated their privacy rights. NASA, they said, had not established a legitimate need for such extensive investigations about low-risk employees like themselves who did not have security clearances or handle confidential information. Dr. Nelson, for example, specializes in solar system science — concerning, for example, Jupiter’s moon Io and Titan, a moon of Saturn — and publishes his work in scientific journals

“It was an invitation to an open-ended fishing expedition,” Dr. Nelson said of the background checks.

In friend of the court briefs for Dr. Nelson, privacy groups cited many data security problems at federal agencies, arguing that there was a risk that NASA was not equipped to protect the confidential details it was collecting about employees and contractors.

In 2008, the United States Court of Appeals for the Ninth Circuit in San Francisco temporarily halted the background checks, saying that the case had raised important questions about privacy rights. But last year, the Supreme Court upheld the background investigations of employees of government contractors.

Dr. Nelson said he retired from the Jet Propulsion Laboratory last June rather than submit to a background check. He now works as a senior scientist at the Planetary Science Institute of Tucson.

NASA has contracted with ID Experts, a data breach company, to help protect employees whose data was contained on the stolen laptop against identity theft. Mr. Jacobs, the NASA spokesman, said the agency has encrypted almost 80 percent of its laptops and plans to encrypt the rest by Dec. 21. He added that he too received a letter from NASA warning that his personal information might have been compromised by the laptop theft.

Former baseball union head Miller dead at 95

Marvin Miller, the union leader who created free agency for baseball players and revolutionized professional sports with multimillion dollar contracts, died Tuesday. He was 95.

Miller died at his home in Manhattan at 5:30 a.m., said his daughter Susan Miller. He had been diagnosed with liver cancer in August.

In his 16 years as executive director of the Major League Players Association, starting in 1966, Miller fought owners on many fronts, winning free agency for the players in December 1975. He may best be remembered, however, as the man who made the word "strike" stand for something other than a pitched ball.

Miller, who retired and became a consultant to the union in 1982, led the first walkout in the game's history 10 years earlier. On April 5, 1972, signs posted at major league parks simply said "No Game Today." The strike, which lasted 13 days, was to be followed by a walkout during spring training in 1976 and a midseason job action that darkened the stadiums for seven weeks in 1981.

Miller's ascension to the top echelon among sports labor leaders was by no means free from controversy among those he would represent. Players from the Los Angeles Dodgers, Atlanta Braves, California Angels and San Francisco Giants opposed his appointment as successor to Milwaukee Circuit Court Judge Robert Cannon, who had counseled them on a part-time but unpaid basis.

Miller overcame the opposition, however, due in part to his demeanor.

"Some of the player representatives were leery about picking a union man," Hall of Fame pitcher and U.S. Senator Jim Bunning, a member of the screening committee that recommended Miller, recalled in a 1974 interview. "But he was very articulate ... not the cigar-chewing type some of the guys expected."

Munich Subway Photos Resemble Abandoned Kubrickian Spacecraft

Nick Frank likes to summarize his approach to photography with one phrase: “Reduce to the max.”

Get to the point. Remove all distractions. It’s a framework that lends itself well to Frank’s series on subway stations in Munich, Germany, where he lives.

“Pictures are often overloaded with information so what I’m doing is trying to flatten the image until you see the essence of the main subject,” he says.

The Munich subway, or U-Bahn, began running in 1971 right before the 1972 Olympics and is known for the bright color schemes and artistic designs that line many of the subway’s 100 stations. In a 1997 book by Christoph Hackelsberger, a member of the city’s subway planning council is quoted as saying that transit stations should “radiate a positive mood” and purposefully “help make a passenger’s wait more pleasant.”

Many of the stations are designed by well-known German architects and the subways themselves are used by hundreds of millions of people each year.

To avoid the crowds and get the kind of clean, empty shots that make up the series, Frank says he has to show up between 5:30 and 6 a.m. on a Sunday morning because that’s the only time the subways aren’t packed. Even then, he says he only has about an hour before things get busy.

Frank is also not shy about using Photoshop to clean things up even further. The gist of the photo is still present, but he’s not afraid to remove trash from the floors or cut a stray person from the background, all with the end goal of trying to create the kind of singular focus that makes his photos pop.

“My photos are not about reality,” he says. “It’s about what I’m seeing.”

He says he was originally drawn to subways not only because many of them are architecturally interesting but also because they tend to be places of creativity. Like many people who ride the trains to work, Frank says he does some of his best thinking on his morning and afternoon commute.

“You usually use the time in the subway to reflect on your day,” he says. “It’s not about talking to other people, it’s all about yourself. Most of my advertising ideas are developed in the subway.”

He hopes his photos, with their sharp lines, symmetry and clear focus, help people call up a similar visceral experience to the one they have while on the trains.

“I want to transport you back,” he says.

Frank will be starting a Kickstarter campaing to fund more subway shoots around the globe so please check his website in early December for more information

New Jersey’s Christie, more popular than ever, seeks re-election

NEW YORK (Reuters) – New Jersey Governor Chris Christie, a Republican star who has enjoying record-high popularity for his hands-on approach to Superstorm Sandy, on Monday filed papers announcing his intention to seek a second term next November.

Christie, a popular surrogate on Republican Mitt Romney‘s failed presidential campaign, delivered the keynote address at the Republican National Convention this summer and is considered a popular choice to run for president in 2016.

Despite his popularity on the national stage, Christie – known for his blunt, sometimes over-the-top style – has sometimes struggled to win over his constituents in liberal New Jersey, where Democrats control both houses of the legislature.

Since Sandy tore through the state on October 29, laying waste to large stretches of the Jersey Shore, Christie’s approval rating has jumped 19 percentage points.

Christie appeared to set politics aside, touring the damage with Democratic President Barack Obama days before November 6 Election Day, and showing a personal touch with residents who lost their homes or loved ones in the storm.

Christie has a 67 percent favorability rating among registered voters, up from 48 percent in October, according to the Rutgers-Eagleton poll.

Since taking office three years ago, Christie’s signature achievement has been a 2011 law that made sweeping changes to the state’s pensions and health benefits for state workers.
