Facebook Instagram use dived after photo fiasco: AppData

SAN FRANCISCO (Reuters) – Facebook Inc’s Instagram lost almost a quarter of its daily users a week after it rolled out and then withdrew policy changes that incensed users who feared the photo-sharing service would use their pictures without compensation.

Instagram, which Facebook bought for $ 715 million this year, saw the number of daily active users who accessed the service via Facebook bottom out at 12.4 million as of Friday, versus a peak of 16.4 million last week, according to data compiled by online tracker AppData.

The popular app, which allows people to add filters and effects to photos and share them over the Internet or smartphones, experienced the drop over the brief, often-volatile holiday period.

Other popular apps also saw slippage in usage, and some were more pronounced. Yelp, for instance, saw daily active users — again via Facebook — slide to a weekly low of half a million on Thursday, from a high of 820,000 one week ago.

Instagram disputed the AppData survey, which was compiled from users that have linked the photo service to their own Facebook accounts, historically between 20 and 30 percent of Instagram members.

“This data is inaccurate. We continue to see strong and steady growth in both registered and active users of Instagram,” a spokeswoman said in an emailed statement on Friday.

Looking out over a broader timeframe, Instagram’s monthly active users edged up to 43.6 million as of Friday, an increase of 1.7 million over the past seven days, according to AppData.

“We’ll have to monitor the data over the coming weeks to gain perspective on trends in Instagram’s performance,” AppData marketing manager Ashley Taylor Anderson said in an email.

ATTENTION-SEEKING

The sharp slide in activity highlighted by AppData was bound to draw attention on the heels of the controversial revision to Instagram’s terms of service that, among other things, allowed an advertiser to pay Instagram “to display your username, likeness, photos (along with any associated metadata)” without compensation.

The subsequent public outrage prompted an apology from Instagram founder Kevin Systrom. Last week, a California Instagram user sued the company for breach of contract and other claims, in what may have been the first civil lawsuit to stem from the controversial change.

Instagram subsequently reverted to some of its original language.

The move renewed debate about how much control over personal data users must give up to live and participate in a world steeped in social media.

Analysts say Facebook, the world’s largest social network, was laying the groundwork to begin generating advertising revenue, by giving marketers the right to display profile pictures and other personal information, such as who users follow in advertisements.

Its shares closed down 13 cents or 0.5 percent at $ 25.91 on the Nasdaq, in line with the broader market.

Actress Katie Holmes’ Broadway show to close

NEW YORK (Reuters) – Actress Katie Holmes‘ return to Broadway has been cut short, with producers announcing that the play “Dead Accounts” in which she co-stars will close on January 6, nearly two months early.

Holmes, the ex-wife of actor Tom Cruise, played Lorna, a wan, beaten-down woman living with her parents in the five-character play by Theresa Rebeck which opened on November 29 to mostly negative reviews.

No reason was given for the play’s early closing, but media reports said it was earning only a fraction of its box office potential.

Many reviewers said Holmes acquitted herself alongside a roster of Broadway veterans, who included Tony-winning actor Norbert Leo Butz as the brother who returns to his Midwestern family and unleashes havoc in the comedy.

The New York Daily News said “she throws herself gamely into her second Broadway show … (but) Holmes’ efforts add up to zilch.”

Most critics laid blame on an undeveloped, sketchy play by the author of last season’s better-received “Seminar.”

Holmes, 34, reached a high-profile divorce settlement with Cruise last summer. She lives in New York with her young daughter, Suri. Holmes will co-star in an upcoming film which will be a modernization of Chekhov’s “The Seagull” along with Allison Janney and William Hurt.

Surgery Returns to NYU Langone Medical Center

Chang W. Lee/The New York Times

Senator Charles E. Schumer spoke at a news conference Thursday about the reopening of NYU Langone Medical Center.

NYU Langone Medical Center opened its doors to surgical patients on Thursday, almost two months after Hurricane Sandy overflowed the banks of the East River and forced the evacuation of hundreds of patients.

While the medical center had been treating many outpatients, it had farmed out surgery to other hospitals, which created scheduling problems that forced many patients to have their operations on nights and weekends, when staffing is traditionally low. Some patients and doctors had to postpone not just elective but also necessary operations for lack of space at other hospitals.

The medical center’s Tisch Hospital, its major hospital for inpatient services, between 30th and 34th Streets on First Avenue, had been closed since the hurricane knocked out power and forced the evacuation of more than 300 patients, some on sleds brought down darkened flights of stairs.

“I think it’s a little bit of a miracle on 34th Street that this happened so quickly,” Senator Charles E. Schumer of New York said Thursday.

Mr. Schumer credited the medical center’s leadership and esprit de corps, and also a tour of the damaged hospital on Nov. 9 by the administrator of the Federal Emergency Management Agency, W. Craig Fugate, whom he and others escorted through watery basement hallways.

“Every time I talk to Fugate there are a lot of questions, but one is, ‘How are you doing at NYU?’ ” the senator said.

The reopening of Tisch to surgery patients and associated services, like intensive care, some types of radiology and recovery room anesthesia, was part of a phased restoration that will continue. Besides providing an essential service, surgery is among the more lucrative of hospital services.

The hospital’s emergency department is expected to delay its reopening for about 11 months, in part to accommodate an expansion in capacity to 65,000 patient visits a year, from 43,000, said Dr. Andrew W. Brotman, its senior vice president and vice dean for clinical affairs and strategy.

In the meantime, NYU Langone is setting up an urgent care center with 31 bays and an observation unit, which will be able to treat some emergency patients. It will initially not accept ambulances, but might be able to later, Dr. Brotman said. Nearby Bellevue Hospital Center, which was also evacuated, opened its emergency department to noncritical injuries on Monday.

Labor and delivery, the cancer floor, epilepsy treatment and pediatrics and neurology beyond surgery are expected to open in mid-January, Langone officials said. While some radiology equipment, which was in the basement, has been restored, other equipment — including a Gamma Knife, a device using radiation to treat brain tumors — is not back.

The flooded basement is still being worked on, and electrical gear has temporarily been moved upstairs. Mr. Schumer, a Democrat, said that a $60 billion bill to pay for hurricane losses and recovery in New York and New Jersey was nearing a vote, and that he was optimistic it would pass in the Senate with bipartisan support. But the measure’s fate in the Republican-controlled House is far less certain.

The bill includes $1.2 billion for damage and lost revenue at NYU Langone, including some money from the National Institutes of Health to restore research projects. It would also cover Long Beach Medical Center in Nassau County, Bellevue, Coney Island Hospital and the Veterans Affairs hospital in Manhattan.

From Times Staff

December 27, 2012, 4:32 p.m.

Gen. H. Norman Schwarzkopf, who commanded the U.S.-led international coalition that drove Saddam Hussein's forces out of Kuwait in 1991, has died, according to a U.S. official. He was 78.

The official told the Associated Press that Schwarzkopf died Thursday in Tampa, Fla. The official wasn't authorized to release the information publicly and spoke on condition of anonymity. A much-decorated combat soldier in Vietnam, Schwarzkopf was known popularly as “Stormin' Norman” for a notoriously explosive temper.

750,000 Android apps invade OS X thanks to BlueStacks App Player

Earlier this year, BlueStacks App Player made headlines by allowing Android apps run on Microsoft’s (MSFT) Windows 8 platform. The company announced on Thursday its App Player is now available in beta form for free on Mac, giving OS X users access to 750,000 Android apps normally reserved for smartphones and tablets.

[More from BGR: Google names 12 best Android apps of 2012]

BlueStacks uses patent-pending virtualization software called “Layercake” to allow Android apps to run on other platforms. It works virtually the same as running Windows within OS X using software such as Parallels or VMWare. The Windows 8 version of BlueStacks has been out since March and has been installed on more than 5 million PCs, which is a good sign that people want to run mobile apps on their computers.

[More from BGR: Samsung looks to address its biggest weakness in 2013]

BGR tested BlueStacks on a mid-2011 MacBook Air running OS X 10.8 Mountain Lion and found performance to be hit or miss. Android apps can be searched and it will list which app stores to download them from, but sometimes apps won’t install properly because of missing code, especially from the Google Play store. Downloading apps from the Amazon (AMZN) Appstore seems to be a better bet, though. If it’s any consolation, Jetpack Joyride and Fruit Ninja are perfectly playable.

BlueStacks works as mostly advertised, but honestly, why bother running Android apps on your Mac? A mouse or trackpad isn’t a better substitute for a touchscreen. But if you must do so, it’s reassuring to know BlueStacks is available.

It is the third marriage for the 37-year-old Winslet. She was previously married to film directors Jim Threapleton and Sam Mendes.

The 34-year-old Rocknroll, who was born Abel Smith, is a nephew of billionaire Virgin Group founder Richard Branson.

The couple had been engaged since last summer.

Winslet won a Best Actress Oscar for her performance in the 2008 film “The Reader.”

By Matt Pearce

December 26, 2012, 4:02 p.m.

Former President George H.W. Bush has been moved to the intensive care unit at Methodist Hospital in Houston, hospital officials confirmed to the Los Angeles Times on Wednesday.

Bush, 88, has been struggling with fever, weakness and a bronchitis-like cough, according to the Associated Press. He was originally planning to spend Christmas at home, but that plan was prevented by high fever.

Bush originally was checked into the hospital in November with bronchitis symptoms.

Bush suffers from vascular Parkinson’s disease and missed the Republican National Convention this year.

Mint, otro Linux para quienes quieren explorar el mundo fuera de Windows

Una de las grandes virtudes de Linux (un sistema operativo libre para PC y otros dispositivos) es la cantidad innumerable de versiones disponibles. Estas distribuciones, además, son en su enorme mayoría de uso gratis, y representan una buena alternativa para los que no desean invertir en una licencia de Windows o quieren explorar -sin gastar- alternativas para la computadora hogareña.

Hemos recomendado en varias ocasiones opciones sencillas de usar e instalar que tienen herramientas iguales o muy similares a las que pueden encontrarse en Windows, destacando la ductilidad de las distribuciones disponibles y cómo hacer para probarlas sin complicarse demasiado , usando un CD regrabable o un pendrive, para no afectar el Windows instalado en la computadora.

En los últimos años fue Ubuntu el que más hizo para facilitarle el trabajo a los neófitos que venían de Windows, automatizando y simplificando procesos de instalación, creando un sitio amigable, sumando instrucciones de instalación y uso en lenguaje no técnico e incluso haciendo acuerdo para preinstalarlo en equipos de marca , pero la elección de la interfaz de usuario Unity (algo rígida) le hizo perder adeptos.

Una de las alternativas que venía creciendo en popularidad era Linux Mint (gratis), y los últimos números de DistroWatch , un sitio que lista las diferentes distribuciones y su popularidad, lo dan como el rey de 2012. Mint usa a Ubuntu como base, por lo que aprovecha algunas de sus herramientas (como la que permite instalarlo dentro de Windows para poder usarlo sin afectar la instalación original) y viene con una gran cantidad de componentes multimedia preinstalados, para facilitar la reproducción de audio y video, entre otras cosas (las distribuciones más “puras” suelen evitar esto para promover el uso de estándares libres de audio y video).

Hace poco más de un mes Linux Mint liberó su versión más reciente, Nadia 14, que incluye dos entornos de escritorio que resultarán muy agradables para quienes no se sienten cómodos con Unity, porque mantienen el esquema tradicional de Windows y Gnome 2.x: una barra de herramientas en la parte inferior de la pantalla, ventanas con los botones de control a la derecha, etcétera.

Linux Mint 14 tiene dos versiones: MATE (basado en Gnome 2.x, y cuyo nombre está inspirado en la yerba mate) y Cinnamon (canela, en inglés) de aspecto similar pero con algunos detalles visuales más atractivos: menús de notificaciones más sofisticados, escritorios virtuales persistentes, miniaturas en el administrador de ventanas y más.

cómo instalarlo

Cualquiera de ellas se puede meter en un pendrive o disco externo y correr desde allí o, si se quiere, instalarlas en la PC, junto con Windows (es compatible con Windows 8) o en una partición nueva. Alcanza con descargar el archivo ISO de instalación (hay uno para MATE y otro para Cinnamon). Ese archivo (900 MB, aproximadamente) se puede grabar en un DVD con una aplicación para quemar imágenes de disco: en Windows está el freeware CDBurnerXP , por ejemplo. Con el disco en la lectora, al encender al PC debería cargar primero Mint antes que Windows (si no, habrá que cambiar una configuración en el BIOS). Podremos usarlo como si estuviera instalado en la PC y luego, si queremos, instalarlo en el disco rígido de nuestra computadora, cuidando de hacerlo en una partición vacía o dentro de Windows.

Otra opción es instalarlo en una memoria USB (de 2 GB o más de capacidad). Para eso hay que usar la aplicación Image Writer (gratis, hay que cliquear donde dice win32diskimager-binary.zip para descargar el archivo). Luego habrá que cambiar la extensión del archivo de .ISO a .IMG para que Image Writer reconozca el archivo y pueda copiarlo en el pendrive (atención que borrará todo lo que está allí).

Si al prender la PC con el pendrive conectado no lo reconoce, habrá que cambiar el orden de carga de sistemas operativos, una opción que suele aparecer apenas se prende la PC (y que no estará disponible si la computadora es muy vieja) para ordenarle que cargue primero el contenido de la memoria USB.

Para quienes estén pensando en probar una distribución de Linux y buscan reducir el “choque cultural” con una interfaz de usuario que sea parecida -pero no idéntica- a la del Windows tradicional, y que además sea sencillo de usar, tienen en Linux Mint 14 Nadia una opción muy atractiva.

Natalie Portman, Kristen Stewart most bankable Hollywood stars

NEW YORK (Reuters) – Actresses Natalie Portman and Kristen Stewart are Hollywood’s most bankable stars and provide studios with the highest average returns for their films, according to Forbes.com.

Academy award winner Portman topped the list of best actors for the buck, providing about $ 42.70 for every dollar she earns.

“Black Swan,” for which she won her best actress Oscar, was produced for an estimated $ 13 million and earned $ 329 million in global box office sales.

“We estimate that for every dollar Portman is paid by the studios, she returns $ 42.70. Compare that to Eddie Murphy, our most overpaid star, who returns $ 2.30 for every dollar he gets paid,” Forbes.com said.

“Twilight” star Stewart was not far behind, bringing in $ 40.60. She also topped the Forbes list of highest-earning actresses with an estimated $ 34.5 million in salary in 2012.

“Stewart was able to earn a ton over the last three years and offer a healthy return thanks to ‘Twilight,’” according to Forbes.com. “Even though she was paid $ 25 million to star in the last two films, she was clearly worth the money.”

Forbes.com analyzed salaries, estimated box office grosses from the actor’s last three films over the previous three years to calculate the studio’s return on investment. The most bankable stars tended to be featured in the most profitable films.

Stewart’s two co-stars in the “Twilight” films were also good investments for the studio. Robert Pattinson came in fourth with a return of $ 31.70 and Taylor Lautner was No. 6, making $ 29.50 for the studio for every dollar he was paid.

Q & A: Should Older Adults Be Vaccinated Against Chickenpox?

Q. Should a 65-year-old who has never had chickenpox be vaccinated against it?

A. In someone who has never had chickenpox, the vaccine would protect against a disease that is far more serious in adults than it is in children, said Dr. Mark S. Lachs, director of geriatrics for the NewYork-Presbyterian Healthcare System and professor of medicine at Weill Cornell Medical College.

After childhood chickenpox, the varicella virus is never eliminated from the body but lies dormant in nerve roots. Decades later, it may reactivate along the nerve pathway and cause the very painful rash called shingles, and later, in many cases, a persistent pain called postherpetic neuralgia, or PHN.

Therefore, for most people over 60, the Centers for Disease Control and Prevention recommends the shingles vaccine. It safely reduces (but does not eliminate) the risk of both shingles and PHN in those who have had chickenpox, Dr. Lachs said.

In someone who never had chickenpox, he said, the concern is not shingles but adult chickenpox, which has “fatality rates 25 times higher than in children.”

Such a person should instead be vaccinated against a primary infection with the varicella virus, Dr. Lachs said. The vaccine differs in strength from the one for shingles and is given in two injections, a month apart.
