Suicide Bomber Kills 2 at Somali President's Villa

MOGADISHU, Somalia (AP) — A suicide bomber detonated explosives inside Somalia's presidential palace compound, killing two people, an official said Tuesday.

The man blew himself up Tuesday morning when he was questioned by soldiers manning a checkpoint in the palace complex known as Villa Somalia, said Mohamed Ali, a police officer at the official residence in Mogadishu, the capital.

Villa Somalia has a large compound with several buildings and checkpoints. The bomber was four more checkpoints away from President Hassan Sheikh Mohamud's home, Ali said. The president is said to be out of the country on state business. The checkpoint where the blast took place is near the home of Prime Minister's Abdi Farah Shirdon which is also in the compound, according to officials.

Two soldiers died and three others were wounded in the explosion, said Yusuf Abdi, a military officer at the palace.

Mohamud survived an assassination attempt on his second day in office in September when two suicide bombers blew themselves up while trying to gain access into a heavily guarded hotel serving as his temporary residence.

No one has claimed responsibility for the attack but it falls into a pattern of previous attacks blamed on the al-Qaida-linked rebel group al-Shabab. The extremist group has been waging an insurgency against Somalia's United Nations-backed government.

Mohamud, 56, who was an academic and activist before becoming president, is expected to form the county's first functioning central government since 1991, when warlords overthrew longtime dictator Mohamed Siad Barre.

Since 2004, Somalia has been represented by a U.N.-approved leadership structure called the Transitional Federal Government that until recently only controlled small parts of Mogadishu. That government accomplished little, but since African Union and Somali troops pushed the al-Shabab extremists out of the capital in 2011 and most parts of the country they occupied in 2012, positive momentum new stability is building.

The international community is supporting Mohamud's government saying it's a step toward moving the country out of its failed-state status but that much more remains to be done in a country bloodied by two decades of war.

In a sign of progress, the United States last week officially recognized the Somali government for the first time since Barre's fall 1991.

Mohamud faces an uphill task unifying a fractious country in the face of the Islamist radicals' insurgency and rebuilding a bombed-out infrastructure, food security and institutions. Another challenge is fighting the endemic corruption that plagued previous governments.

Cómo se desarrolló el Linux de las netbooks educativas

La elección de un sistema operativo para una computadora es una situación que, en situaciones cotidianas al ingresar a una tienda de venta de artículos electrónicos, está marcada por la presencia de la plataforma Windows de Microsoft. Nada de esto impide que los usuarios puedan optar por software libre, sin costo alguno al momento de realizar la descarga e instalación, con propuestas como Ubuntu, Fedora o Mint , por mencionar sólo algunas de las alternativas disponibles en Internet.

Esto mismo ocurrió con el plan Conectar Igualdad, que busca desarrollar su propia plataforma basada en GNU-Linux adaptada a las necesidades de la comunidad educativa, tanto para los docentes como para los alumnos.

La inciativa comenzó a tomar forma en 2010, cuando Javier Castrillo comenzó a trabajar en Conectar Igualdad, el programa del gobierno nacional que distribuye computadoras portátiles para alumnos y docentes de escuelas públicas. Desde aquel momento, con el antecedente de haber coordinado la implementación de estas iniciativas en el ambiente educativo, impulsó con su equipo el desarrollo de Huayra, el sistema operativo libre basado en GNU-Linux de las netbooks escolares.

“Debido al porte de este programa era necesaria una plataforma estable, libre, un estándar y sobre todo con soberanía tecnológica, para no depender de ninguna corporación. Con nuestro sistema nos aseguramos que va a ser constante en el tiempo, que va a ser gratuito para todos aquellos que lo quieran descargar y, por sobre todas las cosas, libre. Todo el código está publicado a disposición para que cualquiera que tenga los conocimientos lo pueda auditar y modificar”, asegura Javier Castrillo, coordinador del Proyecto Huayra.

En una entrevista exclusiva con LA NACIÓN , Javier Castrillo habla sobre la plataforma, sus características y los prejuicios que aún existen sobre el software libre.

¿Qué es Huayra?

Es el sistema operativo libre que las netbooks del Programa Conectar Igualdad van a traer instaladas a partir de este año. Además cualquier persona puede descargarlo en su máquina desde huayra.conectarigualdad.gob.ar

Está basado en Debian GNU/Linux, es seguro, ágil y con un desarrollo realizado en la Argentina, teniendo en cuenta las necesidades tanto de estudiantes como de docentes, y manteniendo nuestra identidad nacional.

¿En qué instancia se encuentra el desarrollo?

Está en fase Beta pero ya se puede bajar y utilizar.

Un mito presente en este tipo de plataformas es que muchas personas creen que no hay virus porque no se conoce mucho. Esto no es verdad, no hay virus porque el sistema no admite virus porque, como dije, está todo a la vista. Los servidores de la bases de datos de los bancos, las grandes bases de datos importantes son de código libre, Google es libre, por ejemplo.

¿Por qué pensaron que era necesario desarrollar un sistema operativo basado en software libre?

Porque se estaban dejando tres millones y medio de máquinas en manos de una corporación, que tiene intereses económicos y sus tiempos. Asimismo, por ejemplo, si queríamos hacer un procesador de texto para las comunidades aborígenes no podíamos hacerlo porque no es posible traducir el Word o si necesitábamos adaptar la placa de red, según el tipo de servicio de determinada zona también teníamos inconvenientes. Tener un software de una empresa es como comprarte un auto y tener el capó soldado.

¿Cuáles son las ventajas que presenta utilizar Huayra frente a Windows?

Es libre y puede ser utilizado por cualquier persona de la comunidad; es gratuito, y ofrece la libertad de poder administrar ese código y hacer las reformas que queremos. Uno de los problemas que veíamos era que los profesores traían un programa para compartir con los chicos y ponían el pendrive en cada computadora y lo bajaban, sin darse cuenta que podían utilizar la red de la escuela. Lo que sucede es que configurar una red no es algo trivial. Huayra, en cambio, autoconfigura la red entonces el profesor deja el programa directamente en una carpeta especial que comparte y los alumnos entran allí para utilizar el programa.

¿En qué se benefician los alumnos al utilizar Huayra?

Que el Estado les brinde su propio sistema operativo libre es un beneficio implícito es más seguro y mucho más rápido. Además, está pensado para que corra en las máquinas más livianas y también funciona bien en las máquinas más viejas.

Otra gran ventaja para los chicos es que tienen una herramienta que sale de la propia escuela, con las necesidades y el aporte de su institución. Hay cientos de aplicaciones del equipo de Huayra y aportadas por las comunidades escolares. En total son casi 30.000 piezas de software.

¿La interfaz es similar a la de Windows o los usuarios verán muchos cambios?

Es similar y además encontrarán programas que no tenían en Windows porque son muy caros. En Huayra, por ejemplo, hay un software para hacer animaciones en 3D que si tuviéramos que comprarlo saldría muy caro. También hay editores de fotos similares a Photoshop.

El procesador de textos de Huayra permite guardarlo en un formato de Word. En el pasado había grandes problemas de compatibilidad entre el software libre y el licenciado pero ahora todo ha evolucionado y ya no existen esos inconvenientes.

Las netbooks de Conectar Igualdad son de diez fabricantes distintos, y tuvimos que trabajar bastante para el desarrollo del sistema operativo, cuenta Javier Castrillo, responsable del proyecto Huayra

Todavía nos falta un buen programa de Autocad 3D, pero tenemos Autocad en 2D. Pero tenemos son muchas herramientas de programación y de robótica incluidas dentro de Hayra.

¿Cómo se realizará la capacitación?

Las netbooks de nuestro programa, a partir de 2012, incluyen TV Digital abierta y allí incluye un montón de tutoriales y paso a paso para poder aprender a utilizarla.

Por otro lado, todas las instancias de capacitación que tiene Educar y el Ministerio de Educación van a tener cursos de Huayra tanto para alumnos como para docentes. Y ya se han formado comunidades de Huayra en Facebook y en Twitter que hacen su propia formación y su aporte a la comunidad.

¿Qué obstáculos tuvieron que sortear?

La principal fue la compatibilidad de hardware. Las netbooks de Conectar Igualdad son de diez fabricantes distintos y tuvimos que trabajar bastante para hacer funcionar nuestro sistema en todos los equipos. Después debimos luchar con los prejuicios que difunden los propios monopolios, que dicen que Linux es difícil, por ejemplo.

Pero ahora estamos muy entusiasmados porque las pruebas están saliendo bien y estamos dentro de los tiempos previstos.

¿Cuáles son los principales proyectos?

La primera etapa de Huayra es que funcione bien en todas las netbooks y en eso estamos abocados. Luego estamos pensando en que funcione en tablets y celulares.

También queremos trabajar para que la TV digital no sirva sólo para ver canales sino que podamos interactuar y brindarle, a través de ella, información útil para el ciudadano.

Y queremos fomentar el desarrollo para que los chicos programen, dándoles herramientas para que puedan programar aunque no sepan hacerlo, para que puedan, por ejemplo, hacer sus propios juegos con las características de su región, de su lenguaje, sus costumbres y que lo compartan con la comunidad.

El software libre en Conectar Igualdad

Huayra toma su nombre del vocablo quechua que significa viento, una analogía que los responsables del proyecto buscan reflejar con la filosofía del proyecto, relacionada con la independencia tecnológica y la libertad que ofrece el software libre. “Es una práctica habitual dentro de la comunidad para que cada programa esté ser representado por un animal. Linux eligió el pingüino, nosotros una vaca”, explica Javier Castrillo.

El equipo de trabajo de Huayra consta de 13 personas, divididos en tres áreas: Desarrollo (programadores), Diseño (artistas, historiadores del arte, diseñadores gráficos) y Sistematización (Sociólogos y estadísticos).

Además de Huayra existe la iniciativa de la comunidad de software libre Tuquito, con sendas versiones para las computadoras de las iniciativas OLPC y Conectar Igualdad .

Rupert Sanders' wife files for divorce in LA

LOS ANGELES (AP) — Rupert Sanders' wife has filed for divorce five months after it was revealed the director had a brief affair with actress Kristen Stewart.

Liberty Ross, Sanders' wife of more than nine years, filed for divorce Friday in Los Angeles citing irreconcilable differences.

Ross' filing cites irreconcilable differences for the couple's breakup. They have two children, an 8-year-old daughter and 6-year-old son.

The model-actress is seeking joint custody of the children and spousal support from her estranged husband, who directed Stewart in "Snow White and the Huntsman."

TMZ, which first reported the filing, stated that Sanders also filed divorce paperwork but it was not available on Monday.

Stewart, who has been dating "Twilight" co-star Robert Pattinson, apologized for her fling with Sanders in July after it was revealed by US Weekly.

DealBook Column: Mary Jo White, Nominee for S.E.C.'s 'New Sherrif,' Has Worn Banks' Hat

“You don’t want to mess with Mary Jo.”

That’s what President Obama said about his pick to run the Securities and Exchange Commission, Mary Jo White. The nomination of Ms. White, a former prosecutor who took on the terrorists behind the bombing of the World Trade Center in 1993 and the Mafia boss John Gotti, was meant to signal that the S.E.C. would be getting tough on Wall Street. CBS called her “Wall Street’s new sheriff.” The Wall Street Journal said she would be “putting a tougher face on an agency still tainted by embarrassing enforcement missteps in the run-up to the financial crisis.” The New York Times said her appointment represented a “renewed resolve to hold Wall Street accountable.”

Hold on.

While Ms. White is a decorated prosecutor, she has spent the last decade vigorously defending — and billing by the hour — Wall Street’s biggest banks, as a rainmaking partner at the white-shoe law firm Debevoise & Plimpton. The average partner at the firm was paid $2.1 million a year, according to American Lawyer; but she was no average partner, very likely being paid at least double that. Her husband, John W. White, is a corporate partner at Cravath, Swaine & Moore. He counts JPMorgan Chase, Credit Suisse and UBS as clients. The average partner at Cravath makes $3.1 million. He, too, was a former official at the S.E.C. — he left Cravath to run the corporate division of the S.E.C. starting in 2006 just in time for the run-up to the financial crisis. He left in November 2008, a month after the bank bailouts, to return to Cravath.

It seems Mr. and Ms. White have made a fine art of the revolving door between government and private practice.

So how conflicted is Ms. White? Let’s count the ways.

They are well documented: she was JPMorgan Chase’s go-to lawyer for many of the cases brought against it relating to the financial crisis. She was arm-in-arm with Kenneth D. Lewis, Bank of America’s former chief executive, keeping him out of trouble when the New York attorney general accused Mr. Lewis of defrauding investors by not disclosing the losses at Merrill Lynch before completing Bank of America’s acquisition of the firm. (And empirically, Mr. Lewis did keep crucial information about the deal from investors.)

This is what she had to say about Mr. Lewis, in a court filing submitted on his behalf: “Some have looked to assign blame for every aspect of the financial crisis, even where there is no evidence of misconduct. This case is a product of that dynamic and does not withstand either legal or factual scrutiny.” It was a refrain she often made about her clients related to the financial crisis.

And then there was Senator Bill Frist, the Republican from Tennessee, whom she successfully represented when the S.E.C. and the Justice Department started an investigation into whether he was involved in insider trading in shares of HCA, the hospital chain. She persuaded them to shut down the investigation.

She also worked with Siemens, the German industrial giant, when it pleaded guilty to charges of bribery, paying a record $1.6 billion penalty.

And then, of course, there was John Mack. She worked for the board of Morgan Stanley during a now well-publicized 2005 investigation into insider trading that ended soon after she made a phone call to the S.E.C. Using her connections at the top of the agency, she dialed up Linda Thomsen, then the commission’s head of enforcement, to find out whether Mr. Mack, who was being considered for Morgan Stanley’s chief executive position, was being implicated. He ultimately wasn’t. As the Huffington Post pointed out in a recent article about Ms. White, Robert Hanson, an S.E.C. supervisor, later testified, “It is a little out of the ordinary for Mary Jo White to contact Linda Thomsen directly, but that White is very prestigious and it isn’t uncommon for someone prominent to have someone intervene on their behalf.”

All of Ms. White’s previous engagements create not only an “optics” problem, but a practical, on-the-job problem. She will most likely need to recuse herself from just about anything related to her previous work.

“I will not for a period of two years from the date of my appointment participate in any particular matter involving specific parties that is directly and substantially related to my former employer or former clients, including regulations and contracts,” is the language in an ethics pledge that she will have to agree to follow.

Some appointees, including Mary L. Schapiro, the former chairwoman of the S.E.C., recused themselves from any involvement in work that was related to a previous employer even after the two-year moratorium. Gary Gensler, the chairman of the Commodity Futures Trading Commission, recused himself from the investigation into MF Global because of his previous employment at Goldman Sachs, where Jon Corzine was the firm’s head, even though it had been years since the two had worked together.

And then there is the issue of Mr. White’s husband, who will have a continuing role at Cravath, one of the most pre-eminent firms in the country, whose clients include some of the nation’s largest corporations.

“This president has adopted the toughest ethics rules of any administration in history,” said Amy Brundage, a White House spokeswoman, “and this nominee is no exception. As S.E.C. chair, Mary Jo White will be in complete compliance with all ethics rules.”

None of these conflicts gets at another potential problem for Ms. White. The job of chairwoman of S.E.C. isn’t simply about enforcement; she has a deputy for that. The biggest challenge anyone who takes the job will have to confront over the next several years will be executing and enforcing provisions of Dodd-Frank and working to regulate electronic trading — something that even the most sophisticated financial professionals, let alone a lawyer, often have a tough time understanding. She has zero experience in this area.

Of course, there can always be a value to inviting a onetime rival onto the team.

“I believe she is one of those people who will understand that her public role will be very, very different than her role as a defense lawyer,” Dennis M. Kelleher of Better Markets, a watchdog group, told me. “I don’t think she’s going to be like so many others who don’t get that they have a very different role when they hold high public office.

“No question, she’s said some things that are controversial and questionable,” Mr. Kelleher said. “Moreover, I hope and expect that she will be asked publicly about them in the confirmation process and that she will have convincing answers.”

Of course, if she is confirmed, we must all hope that she can put her previous client relationships behind her and work for her new client — us.

Senators Agree on Blueprint for Immigration

J. Scott Applewhite/Associated Press

Senators Lindsey Graham, left, and Charles E. Schumer, shown in 2011, are two of the eight lawmakers behind the proposal.

A bipartisan group of senators has agreed on a set of principles for a sweeping overhaul of the immigration system, including a pathway to American citizenship for 11 million illegal immigrants that would hinge on progress in securing the borders and ensuring that foreigners leave the country when their visas expire.

The senators were able to reach a deal by incorporating the Democrats’ insistence on a single comprehensive bill that would not deny eventual citizenship to illegal immigrants, with Republican demands that strong border and interior enforcement had to be clearly in place before Congress could consider legal status for illegal immigrants.

Their blueprint, set to be unveiled on Monday, will allow them to stake out their position one day before President Obama outlines his immigration proposals in a speech on Tuesday in Las Vegas, in the opening moves of what lawmakers expect will be a protracted and contentious debate in Congress this year.

Lawmakers said they were optimistic that the political mood had changed since a similar effort collapsed in acrimony in 2010. Senator John McCain, Republican of Arizona and one of the negotiators, said he saw “a new appreciation” among Republicans of the need for an overhaul.

“Look at the last election,” Mr. McCain said Sunday morning on ABC’s “This Week With George Stephanopoulos.” “We are losing dramatically the Hispanic vote, which we think should be ours.” The senator also said he had seen “significant improvements” in border enforcement, although “we’ve still got a ways to go.”

He added, “We can’t go on forever with 11 million people living in this country in the shadows in an illegal status.”

According to a five-page draft of the plan obtained by The New York Times on Sunday, the eight senators — including Mr. McCain; Charles E. Schumer, Democrat of New York; and Lindsey Graham, Republican of South Carolina — have agreed to address the failings of the immigration system in one comprehensive measure, rather than in smaller pieces, and to offer a “tough, fair and practical road map” that would eventually lead to a chance at citizenship for nearly all of the immigrants here illegally.

“We on the Democratic side have said that we are flexible and we want to get a bill,” Mr. Schumer told reporters in New York on Sunday. “But there’s a bottom line, and that’s a path to citizenship for the 11 or so million people who qualify. We’ve made great, great progress with our Republican colleagues.”

Under the senators’ plan, most illegal immigrants would be able to apply to become permanent residents — a crucial first step toward citizenship — but only after certain border enforcement measures had been accomplished.

Among the plan’s new proposals is the creation of a commission of governors, law enforcement officials and community leaders from border states that would assess when border security measures had been completed. A proposal would also require that an exit system be in place for tracking departures of foreigners who entered the country through airports or seaports, before any illegal immigrants could start on a path to citizenship.

The lawmakers intend for their proposals to frame the debate in the Senate, which is expected to take up immigration this spring, ahead of the House of Representatives. Compared with an immigration blueprint from 2011 that White House officials have said is the basis for the president’s position, the senators’ proposals appear to include tougher enforcement and a less direct path for illegal immigrants than Mr. Obama is considering.

In a parallel effort, a separate group of four senators will introduce a bill this week dealing with another thorny issue that is likely to be addressed in a comprehensive measure: visas for legal immigrants with advanced skills in technology and science. The bill, written primarily by Senator Orrin G. Hatch of Utah, a Republican, and Senator Amy Klobuchar of Minnesota, a Democrat, would nearly double the number of temporary visas, known as an H-1B, available each year to highly skilled immigrants. It would also free up more permanent resident visas, known as green cards, so those immigrants could eventually settle in the United States and go on to become citizens.

Providence theater experiments with ‘tweet seats’

PROVIDENCE, R.I. (AP) — Sarah Bertness slipped into her seat at a recent staging of the musical “Million Dollar Quartet” and, when the lights dimmed, started doing something that’s long been taboo inside theaters: typing away at her iPhone.

The 26-year-old freelance writer from Providence wasn’t being rude. She had a spot in the “tweet seat” section at the Providence Performing Arts Center.

The downtown theater is now setting aside a small number of seats — in the back — for those who promise to live-tweet from the performance using a special hash tag. They might offer impressions of the set, music or costumes, lines of dialogue that resonate with them or anything else that strikes them, really.

At “Million Dollar Quartet,” based on the true story of a 1956 recording session that united music greats Johnny Cash, Elvis Presley, Jerry Lee Lewis and Carl Perkins, PPAC for the first time had cast members tweeting from backstage, too.

A growing number of theaters, including some on Broadway, have been experimenting in recent years with tweet seats and other real-time uses of social media as they try to figure out the relationship between the stage and the smartphone.

Some insist the theater should remain a sacred, technology-free place and that allowing the use of phones during a show — even discreetly — only serves as a potential distraction for other patrons. But others say theaters can’t afford not to engage the digital generation, and that the way performances were once enjoyed, in a vacuum, doesn’t hold up anymore.

“I think that it’s important that PPAC and cultural institutions in general kind of jump on the social media bandwagon and learn to engage a broader audience,” said Bertness, who runs the blog The Rhode Islander and is such a big Johnny Cash fan that she showed up to the performance wearing all black. “I think it’s such a valuable tool.”

Scott Moreau, an understudy for Johnny Cash, hadn’t ever tweeted from backstage during a performance. He tried to provide a glimpse of what life’s like on the tour, which he likened to the special features on a DVD. He said he enjoyed getting instant feedback from the tweeters — feedback he shared with other cast members.

“It makes it feel a lot more personal,” Moreau said.

A picture of Moreau that was tweeted out from backstage — he was tweeting in it himself — prompted someone in the tweet seats to declare that’s what the Man in Black would have looked like, with an iPhone.

Other theaters are also trying different digital ways to engage with patrons. In Boston, the Huntington Theater plans to introduce a “Twittermission” where an artist affiliated with the production, or someone from the theater’s staff, answers questions about the show on Twitter during intermissions. The tweets will also be projected on screens in the theater lobby, according to spokeswoman Rebecca Curtiss.

The theater won’t be introducing tweet seats, though.

“We feel strongly that the experience that an audience member has in our theater should be limited to what they are seeing on the stage,” Curtiss said. “When the lights go down and the show begins, we want the art on stage to speak for itself.”

PPAC isn’t sure yet whether any social media buzz generated by those in the tweet seats will have a measurable effect at the box office. But spokeswoman P.J. Prokop said the theater intends to keep the program through the end of the year, and then evaluate it. Those who sit in the tweet seats get their tickets for free.

Kirsten DiChiappari, who has tweeted three shows there to her nearly 1,400 followers, grew up in New Jersey going to Broadway musicals, plays and the opera. The 41-year-old social media consultant from Bristol sees her live-tweeting as a way to lure people from their living rooms, where many are glued to “horrible reality television.”

“It’s kind of a way to tease people back to support the live arts, the real arts, the original arts,” she said. “I feel like once they go, they’ll go again.”

'Argo' on a roll with big win at SAG Awards

LOS ANGELES (AP) — A few weeks ago, the Oscar race looked wide open. The stately, historical "Lincoln" seemed like the safe and likely choice, with the provocative "Zero Dark Thirty" and the quirky and inspiring "Silver Linings Playbook" very much in the mix for the Academy Award for best picture.

But now, an "Argo" juggernaut — an "Argo"-naut, if you will — seems to be rolling along and gathering momentum as we head toward Hollywood's top prize.

The international thriller from director Ben Affleck, who also stars as a CIA operative orchestrating a daring rescue during the 1979 Iranian hostage crisis, received the top honor of best ensemble cast in a movie at Sunday night's Screen Actors Guild Awards, their equivalent of the best-picture Oscar. It's a decent indicator of eventual Academy Awards success, with the two matching up about half the time.

The film, which also stars John Goodman and Alan Arkin as Hollywood veterans who help stage a fake movie as a cover, has received nearly unanimous critical raves and has proven to be a box-office favorite, as well, grossing nearly $190 million worldwide.

But "Argo" also won the Producers Guild of America Award on Saturday night, which is an excellent Oscar predictor, and it earned best picture and director statues from the Golden Globes two weeks earlier. The Directors Guild of America Awards next Saturday will help crystallize the situation even further.

The one tricky thing at work here: Affleck surprisingly didn't receive an Academy Award nomination in the director category, which most often goes hand in hand with best picture. (There are nine best-picture nominees but only five slots for directors.) Only once in modern times has a film won best picture without a directing nomination: 1989's "Driving Miss Daisy." The other two times came in the show's early years, at the first Oscars in 1929 with "Wings" and for 1932's "Grand Hotel."

Asked backstage at the SAG Awards what might happen when the Oscar winners are announced Feb. 24, Affleck said: "I don't do handicapping or try to divine what's going to happen down the road with movies.

"I didn't get nominated as a director and I thought, 'OK, that's that.' Then I remembered that I was nominated as a producer," said Affleck, who already has an original screenplay Oscar for writing 1997's "Good Will Hunting" with longtime friend Matt Damon. "Nothing may happen but it's a wonderful opportunity to be on the ride and I'm really honored."

Many of the usual suspects throughout the lengthy awards season heard their names called again Sunday night, including Daniel Day-Lewis as best actor for his intense, deeply immersed portrayal of the 16th U.S. president in "Lincoln." Accepting the prize on stage, he gave thanks to several of his colleagues including "The Master" star Joaquin Phoenix (who did not receive a SAG nomination), Leonardo DiCaprio and Liam Neeson.

Backstage, Day-Lewis elaborated for reporters that DiCaprio urged him to stick with Steven Spielberg's project, which was in the works for many years.

"He said, 'Don't give up, he's the greatest man of the 19th century,'" Day-Lewis said. "So this is all Leo's fault."

His co-star, Tommy Lee Jones, also won again in the supporting-actor category for his lacerating portrayal of abolitionist Thaddeus Stevens in Spielberg's Civil War epic.

Anne Hathaway, the front-runner for best supporting actress at the Oscars and a winner already at the Golden Globes, won at the SAGs for her performance as the doomed prostitute Fantine in the gritty musical "Les Miserables."

"I'm just thrilled I have dental," Hathaway joked on stage.

But in the already-tight best actress race, Jennifer Lawrence made things a little more interesting in winning for the drama "Silver Linings Playbook." The 22-year-old plays a damaged young widow opposite Bradley Cooper, whose character is fresh out of a mental institution. Jessica Chastain, the winner at the Golden Globes, has been her main competition as a driven CIA operative searching for Osama bin Laden in "Zero Dark Thirty."

Lawrence said on stage that she got her SAG card at 14 — which was only eight short years ago — for a promo for the MTV reality series "My Super Sweet 16," which she said felt like the best day of her life.

"And now I have this naked statue which means that some of you even voted for me, and that is an indescribable feeling," she said.

On the television side, the popular PBS series "Downton Abbey" bested more established shows like "Mad Men" to win the TV drama cast award in just its first nomination. "Modern Family won the comedy cast prize for the third straight year.

And Dick Van Dyke received the guild's life-achievement award, an honor he presented last year to his "The Dick Van Dyke Show" co-star, Mary Tyler Moore.

After receiving a lengthy standing ovation from the audience, he asked his fellow actors, "Aren't we lucky that we found a line of work that doesn't require growing up?"

Well: Keeping Blood Pressure in Check

Since the start of the 21st century, Americans have made great progress in controlling high blood pressure, though it remains a leading cause of heart attacks, strokes, congestive heart failure and kidney disease.

Now 48 percent of the more than 76 million adults with hypertension have it under control, up from 29 percent in 2000.

But that means more than half, including many receiving treatment, have blood pressure that remains too high to be healthy. (A normal blood pressure is lower than 120 over 80.) With a plethora of drugs available to normalize blood pressure, why are so many people still at increased risk of disease, disability and premature death? Hypertension experts offer a few common, and correctable, reasons:

¶ About 20 percent of affected adults don’t know they have high blood pressure, perhaps because they never or rarely see a doctor who checks their pressure.

¶ Of the 80 percent who are aware of their condition, some don’t appreciate how serious it can be and fail to get treated, even when their doctors say they should.

¶ Some who have been treated develop bothersome side effects, causing them to abandon therapy or to use it haphazardly.

¶ Many others do little to change lifestyle factors, like obesity, lack of exercise and a high-salt diet, that can make hypertension harder to control.

Dr. Samuel J. Mann, a hypertension specialist and professor of clinical medicine at Weill-Cornell Medical College, adds another factor that may be the most important. Of the 71 percent of people with hypertension who are currently being treated, too many are taking the wrong drugs or the wrong dosages of the right ones.

Dr. Mann, author of “Hypertension and You: Old Drugs, New Drugs, and the Right Drugs for Your High Blood Pressure,” says that doctors should take into account the underlying causes of each patient’s blood pressure problem and the side effects that may prompt patients to abandon therapy. He has found that when treatment is tailored to the individual, nearly all cases of high blood pressure can be brought and kept under control with available drugs.

Plus, he said in an interview, it can be done with minimal, if any, side effects and at a reasonable cost.

“For most people, no new drugs need to be developed,” Dr. Mann said. “What we need, in terms of medication, is already out there. We just need to use it better.”

But many doctors who are generalists do not understand the “intricacies and nuances” of the dozens of available medications to determine which is appropriate to a certain patient.

“Prescribing the same medication to patient after patient just does not cut it,” Dr. Mann wrote in his book.

The trick to prescribing the best treatment for each patient is to first determine which of three mechanisms, or combination of mechanisms, is responsible for a patient’s hypertension, he said.

¶ Salt-sensitive hypertension, more common in older people and African-Americans, responds well to diuretics and calcium channel blockers.

¶ Hypertension driven by the kidney hormone renin responds best to ACE inhibitors and angiotensin receptor blockers, as well as direct renin inhibitors and beta-blockers.

¶ Neurogenic hypertension is a product of the sympathetic nervous system and is best treated with beta-blockers, alpha-blockers and drugs like clonidine.

According to Dr. Mann, neurogenic hypertension results from repressed emotions. He has found that many patients with it suffered trauma early in life or abuse. They seem calm and content on the surface but continually suppress their distress, he said.

One of Dr. Mann’s patients had had high blood pressure since her late 20s that remained well-controlled by the three drugs her family doctor prescribed. Then in her 40s, periodic checks showed it was often too high. When taking more of the prescribed medication did not result in lasting control, she sought Dr. Mann’s help.

After a thorough work-up, he said she had a textbook case of neurogenic hypertension, was taking too much medication and needed different drugs. Her condition soon became far better managed, with side effects she could easily tolerate, and she no longer feared she would die young of a heart attack or stroke.

But most patients should not have to consult a specialist. They can be well-treated by an internist or family physician who approaches the condition systematically, Dr. Mann said. Patients should be started on low doses of one or more drugs, including a diuretic; the dosage or number of drugs can be slowly increased as needed to achieve a normal pressure.

Specialists, he said, are most useful for treating the 10 percent to 15 percent of patients with so-called resistant hypertension that remains uncontrolled despite treatment with three drugs, including a diuretic, and for those whose treatment is effective but causing distressing side effects.

Hypertension sometimes fails to respond to routine care, he noted, because it results from an underlying medical problem that needs to be addressed.

“Some patients are on a lot of blood pressure drugs — four or five — who probably don’t need so many, and if they do, the question is why,” Dr. Mann said.

Stanley Karnow, Historian and Journalist, Is Dead at 87

Stanley Karnow, a Pulitzer Prize-winning historian and journalist who produced acclaimed books and television documentaries about Vietnam and the Philippines in the throes of war and upheaval, died on Sunday at his home in Potomac, Md. He was 87.

The cause was congestive heart failure, said Mr. Karnow’s son, Michael.

For more than three decades Mr. Karnow was a correspondent in Southeast Asia, working for Time, Life, The Saturday Evening Post, The Washington Post, NBC News, The New Republic, King Features Syndicate and the Public Broadcasting Service. But he was best known for his books and documentaries.

He was in Vietnam in 1959, when the first American advisers were killed, and lingered long after the guns fell silent, talking to fighters, villagers, refugees, North and South Vietnamese political and military leaders, the French and the Americans, researching a people and a war that had been little understood.

The result was the 750-page book “Vietnam: A History,” published in 1983, and its companion, a 13-hour PBS documentary, “Vietnam: A Television History.” Unlike many books and films on Vietnam in the 1960s and ’70s and the nightly newscasts that focused primarily on America’s role and its consequences at home and abroad, Mr. Karnow addressed all sides of the conflict and traced Vietnam’s culture and history.

“Vietnam: A History” was widely praised and a best seller. The documentary, with Mr. Karnow as chief correspondent, was at the time the most successful ever produced by public television, viewed by an average of nearly 10 million people a night through 13 episodes. It won six Emmy Awards, as well as Peabody, Polk and duPont-Columbia awards.

Six years later, Mr. Karnow delivered his second comprehensive book and television examination of a Southeast Asian nation. The book, “In Our Image: America’s Empire in the Philippines” (1989), was a panorama of centuries of Filipino life under Spanish and American colonial rule, followed by independence under sometimes corrupt American-backed leaders. It won the 1990 Pulitzer Prize for history.

Narrated by Mr. Karnow, the three-part PBS documentary “The U.S. and the Philippines: In Our Image” traced America’s paternalistic colonial rule in the Philippines, the shared suffering of Filipinos and Americans under a cruel Japanese occupation in World War II, and Manila’s postwar independence under regimes nominally democratic but repressive, corrupt or indifferent to the miseries of its people.

Mr. Karnow also wrote “Mao and China: From Revolution to Revolution” (1972) and was a co-author of or contributor to books based on his years in Asia, including “Asian-Americans in Transition” (1992), “Passage to Vietnam” (1994), “Mekong” (1995) and “Historical Atlas of the Vietnam War” (1995).

Early in his career he lived in Paris for a decade, and in 1997 he published a memoir, “Paris in the Fifties.” A nostalgic reporter’s notebook of life among the cafe philosophers, berated musicians and pseudo-revolutionary artistes, it danced with digressions about taxes, restaurants, the guillotine, Hemingway, Charles de Gaulle and the Devil’s Island penal colony.

In its range, learning and appetite for fun, Bernard Kalb, the former CBS reporter and Mr. Karnow’s friend since Vietnam, told The Associated Press in 2009, the memoir was vintage Karnow. “Stanley has a great line about how being a journalist is like being an adolescent all your life,” he said.

Stanley Karnow was born in Brooklyn on Feb. 4, 1925, the son of Harry and Henriette Koeppel Karnow. He grew up in a city with more than a dozen daily newspapers and decided early that he wanted to become a reporter. He served in the Army Air Forces in World War II. After graduating from Harvard with a bachelor’s degree in 1947, he sailed for France, intending to spend the summer. He stayed for a decade.

This article has been revised to reflect the following correction:

Correction: January 28, 2013

An earlier version of this article misstated the year in which Stanley Karnow was a Nieman Fellow at Harvard University. It was 1958, not 2002. The article also misspelled the name of the Nieman Fellowship.

North Korean Leader Vows ‘High-Profile’ Retaliation

Kim Jong-un, the North Korean leader, has vowed to take “substantial and high-profile important state measures” and ordered his top military and party officials of what to do to retaliate against American-led United Nations sanctions on the country, the North’s official media reported on Sunday.

North Korea did not clarify what those measures might be, but it referred to a series of earlier statements in which Mr. Kim’s government has threatened to launch more long-range rockets and conduct a third nuclear test to build an ability to “target” the United States.

Mr. Kim threw his weight behind his government’s escalating standoff with Washington when he called a meeting of top security and foreign affairs officials and gave an instruction in his name. He inherited the supreme party and military leadership from his father, Kim Jong-il, who died in December 2011.

By calling such a meeting and having it reported in state news media, Mr. Kim seemed to assert his leadership in what his country called an “all-out action” against the United States, as opposed to his father, who tended to remain reclusive during similar confrontations.

“At the consultative meeting, Kim Jong-un expressed the firm resolution to take substantial and high-profile important state measures in view of the prevailing situation,” said the North’s Korean Central News Agency, or K.C.N.A. “He advanced specific tasks to the officials concerned.”

The K.C.N.A. dispatch, which was distributed on Sunday, was dated Saturday, indicating that the meeting in Pyongyang took place then. That was the same day on which the North’s main party newspaper, Rodong Sinmun, said that the United Nations Security Council’s resolution last Tuesday calling for tightening sanctions against the North left it with “no other option” but a nuclear test.

“A nuclear test is what the people demand,” it said in a commentary.

The resolution was adopted unanimously — with the support of the North’s traditional protector, China — as punishment for its Dec. 12 rocket launching. The Security Council determined that the launching was a cover for testing intercontinental ballistic missile technology and a violation of its earlier resolutions banning North Korea from such tests.

The North rejected the old resolutions, as well as the latest, insisting that launching rockets to put satellites into orbit was its sovereign right. Its successful rocket launching in December, coming after a failure last April, was the most visible achievement Mr. Kim’s government could present for its people, who have suffered decades of poverty and isolation. In North Korean propaganda, defending its rocket program is likened to protecting national pride and independence — even if it has to pay economic prices.

Last Thursday, North Korea said that its drive to rebuild its moribund economy and its rocket program, until now billed as a peaceful space project, would be adjusted into efforts to foil United States hostilities. On Sunday, it said the Security Council’s action “has thrown a grave obstacle” to its efforts to focus on “economic construction so that the people may not tighten their belts any longer.”

Still, it said it had to “defend its sovereignty by itself” because “different countries concerned” failed to “fairly solve the problem.” In the past few days, North Korea, without citing China by name, expressed bitterness and defiance against its long-time Communist ally for endorsing the American-led Security Council resolution. On Saturday, Rodong reaffirmed its dislike of “sadae,” or toadying big countries, including China.

China provides all of North Korea’s fuel and remains its biggest trade partner, but analysts believe that its influence is limited on the recalcitrant government in Pyongyang. Beijing has been thus far reluctant to use its economic leverage, fearing it could only drive its neighbor into more provocations and harming China’s interest in keeping stability in the region.

International attention has focused on the Punggye nuclear test site in northeastern North Korea, where the country conducted its two previous underground nuclear tests, in 2006 and 2009. Enough preparations have been made there recently that a third test could happen on short notice from the Pyongyang leadership, South Korean officials said.

In a report issued on Sunday, the Institute for National Security Strategy, a research organization affiliated with South Korea’s main intelligence service, said that North Korea may use provocations this year to tame the incoming government of President-elect Park Geun-hye, who will be sworn in next month.

“It will wait and see until the new government’s North Korea policy shapes up,” it said. “If the policy is not favorable, the North may lash out with provocations.”
