Stuxnet Missing Link Found, Resolves Some Mysteries Around the Cyberweapon

As Iran met in Kazakhstan this week with members of the UN Security Council to discuss its nuclear program, researchers announced that a new variant of the sophisticated cyberweapon known as Stuxnet had been found, which predates other known versions of the malicious code that were reportedly unleashed by the U.S. and Israel several years ago in an attempt to sabotage Iran’s nuclear program.

The new variant was designed for a different kind of attack against centrifuges used in Iran’s uranium enrichment program than later versions that were released, according to Symantec, the U.S-based computer security firm that reverse-engineered Stuxnet in 2010 and also found the latest variant.

The new variant appears to have been released in 2007, two years earlier than other variants of the code were released, indicating that Stuxnet was active much earlier than previously known. A command-and-control server used with the malware was registered even earlier than this, on Nov. 3, 2005.

Like three later versions of Stuxnet that were released in the wild in 2009 and 2010, this one was designed to attack Siemens PLCs used in Iran’s uranium enrichment program in Natanz.

But instead of changing the speed of spinning centrifuges controlled by the PLCs, as those later versions did, this one focused on sabotaging the operation of valves controlling the flow of uranium hexaflouride gas into the centrifuges and cascades — the structure that connects multiple centrifuges together so that the gas can pass between them during the enrichment process. The malware’s goal was to manipulate the movement of gas in such a way that pressure inside the centrifuges and cascade increased five times the normal operating pressure.

“That would have very dire consequences in a facility,” says Liam O’Murchu, manager of security response operations for Symantec. “Because if pressure goes up, there’s a good chance the gas will turn into a solid state, and that will cause all sorts of damage and imbalances to the centrifuges.”

The new finding, described in a paper released by Symantec on Tuesday (.pdf), resolves a number of longstanding mysteries around a part of the attack code that appeared in the 2009 and 2010 variants of Stuxnet but was incomplete in those variants and had been disabled by the attackers.

The 2009 and 2010 versions of Stuxnet contained two attack sequences that each targeted different models of PLCs made by Siemens being used in Iran’s uranium enrichment plant — the Siemens S7-315 and S7-417 models of PLC.

In these later variants of Stuxnet, however, only the 315 attack code worked. The 417 attack code had been deliberately disabled by the attackers and was also missing important blocks of code that prevented researchers from determining definitively what it was designed to do. As a result, researchers have long guessed that it was used to sabotage valves, but couldn’t say for certain how it affected them. There were also mysteries around why the attack code was disabled — was it disabled because the attackers had failed to finish the code or had they disabled it for some other reason?

The 2007 variant resolves that mystery by making it clear that the 417 attack code had at one time been fully complete and enabled before the attackers disabled it in later versions of the weapon. And because the 2007 variant only contained the 417 attack code — with no code attacking the Siemens 315 PLC — it appears that the attackers disabled the 417 code in later versions because they wanted to change their tactics, dropping their focus on sabotaging the valves in order to focus instead on sabotaging the spinning centrifuges.

Recipes for Health: Roasted Carrots and Scallions — Recipes for Health

Andrew Scrivani for The New York Times

I bought incredibly sweet, thick red scallions and multicolored bunches of carrots from a farmer at my market and roasted them with fresh thyme. Then I sprinkled on some crushed toasted hazelnuts, which contributed a nice crunchy texture and nutty finish to the dish. If you have a bottle of hazelnut oil or walnut oil on hand, a small drizzle just before serving is a welcome touch.

1 ounce hazelnuts (about 1/4 cup)

1 pound carrots, preferably young small carrots, any color (but a mix is nice)

1 bunch white or purple spring onions or scallions

Salt and freshly ground pepper

2 teaspoons fresh thyme leaves

2 tablespoons extra virgin olive oil

Optional: a drizzle of hazelnut oil or walnut oil for serving

1. Preheat the oven to 325 degrees. Place the hazelnuts on a baking sheet and roast for 8 to 10 minutes, until they smell toasty and they are golden all the way through (cut one in half to check). Remove from the oven and turn up the heat to 425 degrees.

2. Immediately wrap the hazelnuts in a clean, dry dish towel. Rub them in the towel to remove the skins. Then place the skinned hazelnuts in a plastic bag or, if you have one, a disposable pastry bag and set on your work table in one layer. Use a rolling pin to crush the nuts by rolling over them with the pin. Set aside.

3. Line a sheet pan with parchment or oil a baking dish large enough to fit all of the vegetables in a single layer. If the carrots are small, just peel and trim the tops and bottoms. If they are medium-sized, peel, cut in half and cut into 4-inch lengths. Quarter large carrots and cut into 4-inch lengths. Trim the root ends and greens from the spring onions or scallions. If they are bulbous, cut them in half. Season with salt and pepper, add the thyme and olive oil and toss well, either directly on the pan or in the dish or in a bowl. Spread in an even layer in the baking dish or on the baking sheet.

4. Roast in the oven for 20 to 30 minutes, stirring every 10 minutes. The onions may be done after 10 minutes – they should be soft and lightly browned. Remove them from the pan if they are and hold on a plate. When the carrots and onions are tender and browned in places, remove from the oven. Add the onions back into the mix if you removed them and toss together. Sprinkle on the toasted ground hazelnuts, drizzle on the optional nut oil, and serve.

Yield: Serves 4

Advance preparation: The vegetables can hold for a few hours once roasted; cover and reheat in a medium oven.

DealBook: Wall Street Pay Rises – for Those Who Still Have a Job

It’s nice work – if you can get it.

Wall Street has cut thousands of jobs over the past year or so. On Tuesday, JPMorgan Chase, one of the country’s biggest banks, announced that it was eliminating 4,000 more jobs through layoffs and attrition, adding its name to a string of large banks that continue to cut jobs to reduce expenses.

The good news? For the employees who remain, pay is up, according to a report released Tuesday by the New York State comptroller.

This may seem surprising given the outcry over high compensation during the financial crisis. In recent years, however, faced with greater regulation, a slow economic recovery and the loss of once big moneymaking businesses like selling products tied to mortgages, the banks have tried instead to cut people rather than pay, which they argue is needed in order to retain talent that might otherwise leave for better paying jobs at hedge funds or elsewhere.

The average cash bonus for people employed in New York City in the financial industry rose by roughly 9 percent, to $121,900, in 2012 and cash bonuses in total are forecast to increase by roughly 8 percent to $20 billion this year, said Thomas P. DiNapoli, the comptroller.

In recent years some firms have deferred cash payments to employees, and Mr. DiNapoli said part of the increase in the 2012 numbers was cash promised in recent years was actually paid out in 2012. He said that it was “tough” to break out what percentage of the total are deferrals but he believed that it was still a small part of the total.

All told, the average pay package for securities industry employees in New York was $362,900 in 2011, the last year for which data is available, almost unchanged from 2010.

Wall Street jobs are harder to get than they were just a few years ago, but for those who can get their foot in the door finance remains the best paying sector in New York City, Mr. DiNapoli told reporters during a confernce call

“Profits and bonuses rebounded in 2012, but the industry is still restructuring. Despite its smaller size, the securities industry is still a very important part of the New York City and New York state economies,” he said.

The current economic recovery, he said, is being driven by industries other than Wall Street, which he said has regained only 30 percent of the jobs lost during the downturn. The securities industry in New York City lost 28,300 jobs during the financial crisis and has added only 8,500 since, a net loss of 19,800 jobs. New York City financial industry employment totaled 169,700 at the end of 2012.

Before the start of the financial crisis, business and personal income tax collections from Wall Street related activities accounted for up to 20 percent of New York State tax revenues. In 2012, that contribution fell to just 14 percent.

“Wall Street is still in transition, but it is very slowly adjusting to changes in its economic and regulatory environment,” he said.

Oscars 2013: An 'Argo' night at Academy Awards

For the second straight year, the movie business fell for itself.

"Argo" — in which a Hollywood producer and makeup artist help engineer the rescue of six Americans from Iran — won the top prize at the 85th Academy Awards, one year after the silent film story "The Artist" took the best picture Oscar.

"I never thought I'd be back here. And I am," producer-director Ben Affleck said in accepting the best picture trophy Sunday night, 15 years after he won an original screenplay Oscar for "Good Will Hunting" and then saw his career fall into a tailspin that included "Gigli" and "Daredevil."

FULL COVERAGE: Oscars 2013 | Winners

"It doesn't matter how you get knocked down in life. That's going to happen," said Affleck, who wasn't nominated for directing "Argo," one of nine films in the best picture race. "All that matters is that you've got to get up."

"Argo," which became the first movie to win best picture without its director being nominated since 1989's "Driving Miss Daisy," collected two other Academy Awards, for editing and adapted screenplay. But it was not the evening's most recognized film: That honor went to Ang Lee's "Life of Pi," which won four Oscars — for directing, visual effects, cinematography and score.

"Thank you, movie god," said Lee, whose movie came into the evening with 11 nominations, one behind Steven Spielberg's "Lincoln." The film about the 16th president helped Daniel Day-Lewis make movie history, as he became the only man to ever win three lead actor statuettes. "Lincoln" won one other prize, for production design.

The song-and-dance heavy ceremony, hosted by Seth MacFarlane, hewed closely to a traditional awards show script, but there were several surprises. First Lady Michelle Obama, who joined the ABC telecast from the White House, announced "Argo" as the best picture. And the ceremony featured only the sixth tie in Oscar history and the first since 1994, with the sound editing award split between "Zero Dark Thirty" and "Skyfall." For the first time in Oscar history, six best picture nominees were $100-million blockbusters.

The ceremony was billed as a tribute to music in film, and boasted a number of extravagant musical numbers — including a medley of songs from movie musicals and an appearance by Barbra Streisand, who sang "The Way We Were." The telecast also paid homage to the long running James Bond series, with Adele singing the theme from "Skyfall" and Dame Shirley Bassey performing the theme from 1964's "Goldfinger."

Oscars 2013: Nominee list | Red carpet | Highlights

Jennifer Lawrence, 22, nabbed the lead actress prize for her role as an emotionally unstable widow in "Silver Linings Playbook" — and promptly tripped over her long dress walking up the stairs to accept her statuette. The crowd quickly gave her a standing ovation. "You guys are just standing up because you feel bad that I fell and that's embarrassing," Lawrence said to the applauding crowd at the Dolby Theatre.

The evening's very first award — for supporting actor — was a shocker, with long shot Christoph Waltz winning for his role as bounty hunter Dr. King Schultz in Quentin Tarantino's "Django Unchained" over favored contenders Robert De Niro ("Silver Linings Playbook") and Tommy Lee Jones ("Lincoln"). Waltz, who won the same award three years ago for Tarantino's "Inglourious Basterds," dedicated his prize to his writer-director, who also won the Oscar for original screenplay. "We participated in a hero's journey — the hero being Quentin," Waltz said.

Tarantino pulled off a mild surprise with the screenplay triumph for his slave-revenge tale. He dedicated his award to his eclectic cast of actors. "I actually think if people know my movies 30-50 years from now it's because of the characters I create," Tarantino said.

Anne Hathaway's supporting actress win for her emotionally raw portrayal of a doomed seamstress in "Les Misérables" was hardly as startling. The 30-year-old had been the odds-on favorite to win since the film first screened for members of the Motion Picture Academy in late November. "It came true," she stage-whispered as she picked up her trophy for her performance, the centerpiece of which is the lament "I Dreamed a Dream."

Oscars 2013: Backstage | Quotes | Best & Worst moments

Some of the evening's wins were bittersweet.

The animated feature Oscar was shared by "Brave" directors Mark Andrews and Brenda Chapman, an unusual pairing given that Chapman was fired from the Pixar Animation Studios film and replaced by Andrews in the middle of production. "Making these are a struggle — it's a battle, it's a war," Andrews said backstage. "I was very happy it was him who took my place," Chapman said.

Rhythm & Hues Studios, the company behind "Life of Pi's" visual effects win, recently filed for bankruptcy and laid off hundreds of its employees. As Oscar winner Bill Westenhofer addressed the situation in his acceptance speech, he ran over time and the theme from "Jaws" began to play him off the stage. His microphone was cut off just as he said the words "I urge you all…"

William Goldenberg was a double nominee in the film editing category — he worked on both "Argo" and "Zero Dark Thirty" — and won the prize for Affleck's CIA drama.

"Working at my father's deli, I had to do a million things at one time," Goldenberg said backstage about the best training for his job. "It really does prepare you for the multitasking it takes to be in an editing room."

Darpa Wants to Rethink the Helicopter to Make It Go <em>Way</em> Faster

Helicopters are great. They’re maneuverable in very tight spaces, they haul heavy things relative to their small sizes — and, very importantly, they take off and land vertically, removing the need for a big airstrip or aircraft-carrier deck. That function is so important to the military that the U.S. designed fixed-wing aircraft to do the same thing, like the Marines’ iconic Harrier jet or their weird tilt-rotor Osprey.

And they actually all suck, according to the Pentagon’s blue-sky researchers at Darpa, who are launching an effort to blow up and re-imagine helicopters, jump jets and tilt-rotors. It’s time to make these “VTOL” aircraft — the collective term for Vertical Take-Off and Landing — way, way faster, without sacrificing their ability to hover or other functionality.

Like any aircraft, VTOLs are most vulnerable to enemy attack when they’re taking off and landing. But unlike other aircraft, they’re slow to ascend and descend, a particular problem when an adversary lurking nearby knows exactly what pattern the VTOLs will use to get off the ground and back onto it. And when they’re flying, they’re not going nearly as fast as something with, say, a jet engine. It’s a problem the U.S. military has often encountered in warzones. Anyone who’s taken a ride on a Blackhawk or a Chinook in Afghanistan or Iraq has been very thankful for the guy with the .50-caliber gun hanging out the open back of the helo.

Hence Darpa’s newest aircraft program. It’s called the VTOL X-Plane and officially launches Monday. The idea is to rethink the designs of anything that takes off and lands vertically, to make it faster; hover and cruise more efficiently; and haul more stuff. By the time it’s done in 52 months, it just might result in an aircraft that doesn’t look at all like a helicopter, jump jet or tilt-rotor.

“What we’re interested in doing is flying much faster than we have been able to do with helicopters,” program manager Ashish Bagai told reporters on a conference call. Helos and other VTOL aircraft typically max out at 170 knots. Bagai wants the X-Plane to do 300. “We want to fly at improved efficiencies, both in hover and at forward flight,” he said, “and we want to demonstrate this is possible without sacrificing the ability to do useful work. And to do this concurrently is a very big challenge.”

It’s also not springing up from specific improvements in helicopter or other VTOL capability in the aerospace industry. Nor does it arise from any tech innovations Darpa sees on the horizon. “We have seen in the community a few isolated and novel approaches to addressing this problem but we’re in danger of suffering an attrition in our technology bases,” Bagai said. “This is an opportunity Darpa would like to put forth to advance the state of the art, well beyond where we are today.”

Good luck with that. Helicopters usually get faster by adding power and messing with the rotor placements. (See, for instance, Sikorsky’s funky ’70s-era designs.) But that typically compromises their ability to hover. Nor, Bagai conceded, have fixed-wing VTOLs cracked the speed/hover/power problem. And the V-22 Osprey tilt-rotor has endured more than its fair share of challenges.

All of which raises questions about the VTOL X-Plane’s ability to actually deliver on its promises. Bagai thinks there’s an opportunity for “hybridization” by mashing up the fixed-wing and helicopter design communities, but like many Darpa projects, the program will pulse those communities rather than take advantage of improvements on the cusp of maturity.

Darpa’s setting a “very aggressive” development schedule, Bagai said, that’s targeting a flight test in 42 months. Ten months later, when the program ends, “we want to have demonstrated all our key objectives and have a flying aircraft available,” he said. If it fails, helicopters, jump jets and tilt-rotors won’t be any worse off. If it succeeds, the VTOL X-Plane pretty much represents their next generation.

Quvenzhané Wallis to play title role in “Annie” movie

NEW YORK (Reuters) – Nine-year-old Oscar nominee Quvenzhané Wallis will play the title role in “Annie,” Sony’s Columbia Pictures announced on Sunday.

“Annie” is due to hit theaters in 2014 during the winter holiday season, and is based on the stage play about an orphan’s adventures in finding her family and a better life while overcoming the schemes of orphanage mistress Miss Hannigan.

President of production at Columbia Pictures Hannah Minghella expressed confidence in Wallis’ talent and star power.

“With the recent Academy Award nomination and critical acclaim, Quvenzhané Wallis is a true star and we believe her portrayal as Annie will make her a true worldwide star,” she said.

“She is an extraordinary young talent with an amazing range, not only as an actress but as a singer and dancer, and we can’t wait for audiences to further discover her.”

Among the film’s co-producers are Will Smith, Jada Pinkett Smith and Shawn “Jay-Z” Carter. Carter’s 1998 Grammy-winning album “Vol. 2… Hard Knock Life” contains a hip-hop version of “It’s a Hard Knock Life,” a song from the original Broadway musical “Annie.”

The hit musical was first made into a film starring Carol Burnett as Miss Hannigan in 1982. A made-for-TV version with Kathy Bates in the same role aired on ABC in 1999, and earned two Emmy awards.

Wallis is the youngest actress to ever be nominated for a Best Actress Oscar. She was nominated for her role as Hushpuppy in indie drama “Beasts of the Southern Wild,” which also earned a nod for Best Picture. “Beasts” is Wallis’ first acting job.

Among her other firsts, she will also be the first African-American actress to play Annie, who has been traditionally portrayed as a freckle-faced redhead.

Later this year, she will star alongside Brad Pitt and Michael Fassbender in Steve McQueen’s historical drama “Twelve Years a Slave,” based on the book by Solomon Northup.

Recipes for Health: Root Vegetable Sweetness — Recipes for Health

Andrew Scrivani for The New York Times

Last week I got a Facebook message from a Recipes for Health fan that said: “Help! Drowning in pounds of root vegetables from CSA…would love recipes for sweet potatoes, yellow potatoes, and carrots…” Since root vegetables and tubers keep well and can be cooked up into something delicious even after they have begun to go limp in the refrigerator, this week’s Recipes for Health should be useful. Root vegetables, tubers (potatoes and sweet potatoes, which are called yams by most vendors – I mean the ones with dark orange flesh), winter squash and cabbages are the only local vegetables available during the winter months in colder regions, so these recipes will be timely for many readers.

Roasting is a good place to begin with most root vegetables. They sweeten as they caramelize in a hot oven. I roasted baby carrots and thick red scallions (they may have been baby onions; I didn’t get the information from the farmer, I just bought them because they were lush and pretty) together and seasoned them with fresh thyme leaves, then sprinkled them with chopped toasted hazelnuts. I also roasted a medley of potatoes, including sweet potatoes, after tossing them with olive oil and sage, and got a wonderful range of colors, textures and tastes ranging from sweet to savory.

Sweet winter vegetables also pair well with spicy seasonings. I like to combine sweet potatoes and chipotle peppers, and this time in a hearty lentil stew that we enjoyed all week.

Spicy Lentil and Sweet Potato Stew With Chipotles

The sweetness of the sweet potatoes infuses this Mexican-inspired lentil dish along with the heat of the chipotles, which also have a certain sweetness as well because of the adobo sauce they are packed in. The combination, with the savory lentils, is a winner.

1 tablespoon extra virgin olive oil

1 medium onion, chopped

2 garlic cloves, minced

Salt to taste

2 teaspoons cumin seeds, lightly toasted and ground

2 medium carrots, diced

1 1/2 cups brown or green lentils, rinsed

6 cups water

2 medium-size sweet potatoes (aka yams, with dark orange flesh, 1 to 1 1/4 pounds), peeled and cut in large dice

1 to 2 chipotles in adobo, seeded and chopped (to taste)

2 tablespoons tomato paste

1 bay leaf

1/4 cup chopped fresh cilantro or parsley (to taste)

Lime wedges for serving

1. Heat the olive oil over medium heat in a large, heavy soup pot or Dutch oven and add the onion. Cook, stirring often, until it softens, about 5 minutes, and add the garlic and a generous pinch of salt. Cook, stirring, until the garlic smells fragrant, about 30 seconds, and add the ground cumin seeds and carrots. Stir together for a minute, then add the lentils, water, sweet potatoes, chipotles, tomato paste, salt to taste and the bay leaf. Bring to a boil, reduce the heat, cover and simmer 40 to 45 minutes, until the lentils and sweet potatoes are tender and the broth fragrant. Taste and adjust seasoning. Stir in the cilantro or parsley, simmer for another minute, and serve, passing lime wedges so diners can season their lentils with a squeeze of lime juice if desired.

Yield: Serves 6 to 8

Advance preparation: This will be good for three or four days but it will thicken as the lentils continue to swell. If you want to thin it out, add water or stock.

NBC’s Ratings Plummet From First to Worst

Will Hart/NBC

Megan Hilty, left, and Katharine McPhee in “Smash,” which is back for a second season but is still struggling.

With every passing week, the sudden blossoming of prime-time success that NBC experienced last fall is looking more like a mirage.

Patrick Harbron/NBC

“Do No Harm,” with Stephanie Roth Haberle and Steven Pasquale, was canceled quickly.

The ratings of last September through December, when NBC shocked the television industry by winning 13 of 15 weeks, have dissipated to numbers so small they have not been seen before by any broadcast network — certainly not during a rating period known as a sweeps month, when networks present their strongest programming.

When the official numbers are completed Thursday, NBC will finish this sweeps month not only far behind its regular network competitors, but also well behind the Spanish-language Univision. No broadcast network has ever before finished a television season sweeps month in fifth place.

NBC executives expected a falloff after the N.F.L. season, but last December they expressed hope that some momentum could be sustained. Now, the network is playing by the silver-linings playbook.

“This February was tough, but thankfully the fall did as well as it did,” said Jeff Bader, the chief scheduling executive for NBC. “If we had the fall we were expecting — which was an improvement, but not to be No. 1 — this month would have been a lot harder to take. This is just frustrating.”

It is also likely to be costly. NBC executives previously acknowledged that their entertainment operation has been losing hundreds of millions a year. The financial picture is exacerbated by the dearth of popular shows NBC owns that it can sell in syndication, an area that generates hundreds of millions in profits for competitors, especially CBS.

Advertising executives note that ratings this month on many shows are so low they may force NBC to offer a spate of what are known as make-goods — free commercials to cover shortfalls from rating guarantees. And in less than three months NBC must unveil a new schedule for advertisers, one that will emphasize the improvements of last fall, but will also contain a short list of holdover shows with attractive ratings to sell. That will put great pressure on the lineup of new shows NBC selects.

The network’s prime-time record this month is a litany of ratings sorrows: Shows that looked like hits last fall, like the new comedy “Go On,” have collapsed. New shows, like the comedy “1600 Penn,” started weak and have fallen fast. NBC even had the lowest-rated new network drama of all time, “Do No Harm,” which was rated 0.9 in the 18-49 category for its premiere this month and fell to 0.7 in its second week.

It was canceled after two episodes.

Perhaps more painful, because it was the favorite project of NBC’s top programmer, Robert Greenblatt, has been the fate of the Broadway drama “Smash.” Introduced last winter with great expectations — and a hugely expensive promotion campaign — “Smash” returned three weeks ago to audience indifference. Last week’s episode could not eke out even a 1 rating among viewers aged 18 through 49, the audience NBC sells to advertisers.

Over all, the network’s ratings have fallen so far that no episode of any show on NBC in February came within one million viewers of a show on PBS: “Downton Abbey.” And forget approaching the numbers of a cable hit like AMC’s “The Walking Dead.”

Nothing NBC has put on in prime time has matched even the appeal of the “Talking Dead,” a show with people simply discussing “The Walking Dead.” That show managed a 2.2 rating in the 18-49 audience. NBC’s best prime-time number for the month has been a 2.1, achieved by episodes of “The Biggest Loser” and “The Office,” a comedy that is about to go off the air.

Remarkably, the best-rated show on NBC all month has been “Saturday Night Live,” which produced two original versions in February, both times hitting a 2.3 rating, topping everything else on the network. “SNL,” though, is not even in prime time — and it is 38 years old.

This article has been revised to reflect the following correction:

Correction: February 25, 2013

A picture caption with an earlier version of this article misspelled the given name of an actress in the canceled show “Do No Harm.” She is Stephanie Roth Haberle, not Stepanie.

Oscars stage manager braces for his final cues to the stars

He delivered a forgotten harmonica to Stevie Wonder onstage at the Grammy Awards, supplied a shoulder to lean on for a post-hip-surgery Gregory Peck at the Oscars and served as a human Xanax for hundreds of other stars in the most terrifying and exhilarating moments of their careers.

Stage manager Dency Nelson, 61, works behind the scenes at the Oscars, plus at times the Grammys, Screen Actors Guild Awards, Teen Choice Awards, MTV Movie Awards and other shows. This year will mark his 25th — and last, he said — Academy Awards, as he plans to retire from one of show business' least known but most stressful gigs.

An anonymous but critical piece of the Hollywood awards season machinery, stage managers like Nelson control the chaos of the live TV broadcast — they deliver the correct winning envelopes, ensure that the pop-up microphone actually pops up and, most delicately, orchestrate the flow of talent through the stage wings.

Oscars 2013: Nominee list | Ballot | Trivia | Timeline

An avuncular former hippie with twinkling green eyes, a silver earring and a scruffy, salt-and-pepper beard, Nelson is stationed in the stage-right wings, a hot spot where most of the Oscar telecast's jittery presenters enter and elated winners exit.

"It's like air traffic control," he said one recent afternoon at the Dolby Theatre at the Hollywood & Highland Center, where he was preparing for Sunday's show. "Ninety percent of the people in the room don't know my name, but when they round the corner and come into the wings there's a smile, 'Oh, that guy.'"

Even seasoned performers rely on stage managers for assurance in the unforgiving medium of live TV, and backstage figures like Nelson develop a rapport with stars they see at multiple shows.

Last year, before Meryl Streep stepped onto the Oscar stage to present an award, she reviewed her script, smoothed her gown and cast a tentative glance at Nelson. "You'll push me out when it's time?" she asked. He gently led the actress by the arm to the edge of the curtain, sending her off to face an audience of 40 million.

An hour later, after winning lead actress for "The Iron Lady," the first person an emotional Streep saw was Nelson, with a chair and a welcome water bottle.

"Dency's businesslike, but he makes people comfortable," said American Film Institute founder George Stevens Jr., who met him when the recent college grad was lugging heavy film reels for the L.A.-based nonprofit. Charmed by the young man's work ethic, nearly four decades later Stevens still hires him to stage-manage the "Kennedy Center Honors" and "Christmas in Washington" shows every year.

Many of the approximately 500-person backstage crew at the Oscars have been performers themselves, including head stage manager Gary Natoli (Nelson's boss) and a stage manager who specializes in talent, Valdez Flagg, both former actors and dancers.

TIMELINE: Academy Award winners

According to guild minimums, the stage managers must make at least $746 for a 12-hour day, and many work other steady jobs. Thanks to the proliferation of performance-based reality shows such as "American Idol" and "The Voice," there's a lot of work available for the specialized group who know how to do it.

Nelson has stage-managed the game show "Let's Make a Deal" and the syndicated variety program "The Wayne Brady Show."

"Anyone can do this job as long as nothing goes wrong," said Flagg. "If you can't go with the flow, you won't last. You'll freak out."

The year Wonder forgot his harmonica, for instance, the Grammys crew had to think quickly — how do you subtly signal a blind man? Ultimately, Nelson asked the director to frame a tight shot on the singer's face while he sneaked up from below and tugged on Wonder's pant-leg. At the Emmys, when an impostor tried to walk off with "Hill Street Blues" star Betty Thomas' trophy, Nelson skidded on stage with another.

And then there's that other occupational hazard: jerks. "People are just nervous in some cases and take it out on you," Nelson said with a shrug.

This year's Oscar telecast is a particularly taxing one for the stage crew, with many singing and dancing casts to maneuver. The consequences of a missed cue can be dire — at several points in the show, 34.5-foot lifts built into the stage floor will open to move scenery pieces.

Nelson, who grew up in Menlo Park the son of an Army auditor, originally wanted to be an actor. As a child he hosted the Andy Williams Christmas show by himself in front of the Christmas tree, with a toilet paper roll as a microphone.

After graduating from UC Santa Cruz with a degree in theater, he took a job as a driver and mail clerk for AFI and worked behind the scenes as "the guy who guarded the doughnuts" for the 1970s soap opera parody "Mary Hartman, Mary Hartman" and a cue card man for "Saturday Night Live" and David Letterman.

Along the way he continued to act in commercials, basement theaters and tiny walk-on roles (in Woody Allen's "Manhattan," you can see Nelson stride across Park Avenue carrying an attaché case). "I wasn't really getting anywhere," he said. "I just saw my actor colleagues, their talent, and saw I'm not that."

The frustrated performance experience, however, gives Nelson a nuanced understanding of what the people he's pushing into the lights on Oscar night are feeling. "There have been plenty of times where I have held a trembling hand and smiled," he said. "I so admire anyone who can do that."

The stage crew prepares with the thoroughness of a military campaign. During rehearsals, Nelson marks his show rundown with different colors of highlighters and pens, noting when he'll send a performer upstage or where a piece of scenery will move. Unlike some younger stage managers, he still uses paper, not an electronic device, for storing his "road map."

In a change this year, six college film students will deliver the trophies onstage, instead of the usual cadre of models who float from show to show. On Wednesday, Nelson was coaching them on the subtle art of statuette distribution.

"Let the kiss and hug happen," he said, his hands stained with red ink from jotting notes on his script, six roles of tape swinging from his belt. "Just linger upstage, let that traffic happen."

At Nelson's first Oscars, before the students were born, Jack Lemmon was the host. Over the years, Nelson said he's noticed an evolution in the awards show scene, as older performers who approached show business with a certain gentility have given way to a more casual and sometimes cruder generation.

"I'm no prude, but there was a certain formality and respect to things," he said. "I'm sorry to see it go, although I understand the financial necessity 'cause it's about the ratings."

A married father of one grown daughter, Nelson lives in Hermosa Beach and is active in Democratic party politics and environmental causes; he helped found a nonprofit devoted to alternative vehicles called Plug in America (he owns two electric cars). Especially engaged in the union to which stage managers belong, the Directors Guild of America, this year he received the guild's Franklin J. Schaffner Award for service.

He said he's retiring to devote more time to his political passions, but he also appears ready to shed the pressures of awards season.

"I don't want to make any mistakes," Nelson said. "The worst is just before the show starts. That's awful. That last hour in the wings.... It's not calm inside. As I am nearing my retirement, I just keep thinking of Jack Nicholson's line in 'Terms of Endearment' ... 'Inches from a clean getaway.'"
