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.

Patrick Dempsey brews up coffee shop purchase

LOS ANGELES (AP) — Patrick Dempsey says he wants to rescue a coffee house chain and more than 500 jobs.

The "Grey's Anatomy" star said Wednesday he's leading a group attempting to buy Tully's Coffee. The Seattle-based company filed for Chapter 11 bankruptcy protection in October.

Dempsey said he's excited about the chance to help hundreds of workers and give back to Seattle.

The actor has a strong TV tie to the city: He plays Dr. Derek Shepherd on "Grey's Anatomy," the ABC drama set at fictional Seattle Grace Hospital.

Tully's has 47 company-run stores in Washington and California, as well as five franchised stores and 58 licensed locations in the U.S.

Any sale would have to be approved by a judge. A bankruptcy court hearing is set for Jan. 11 in Seattle.

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.

Patrick Dempsey wants to buy Tully's Coffee

McDreamy latte, anyone?

Patrick Dempsey, the actor who plays Dr. Derek Shepherd on “Grey’s Anatomy,” is leading a group that hopes to purchase Tully’s Coffee -- a coffee shop chain based in Seattle.

Tully’s filed for chapter 11 bankruptcy in October, due to cash flow problems. Since then, the company has closed some of its unprofitable locations and reduced overhead.

Dempsey couched his bid as a way to save jobs in the Seattle area.

“I’m excited about the opportunity to save hundreds of jobs, give back to Seattle and become a larger part of the economic growth and fabric of the community,” he said in a statement. “I’ve always loved this city, and with the purchase of Tully’s Coffee, I plan to spend a lot of time in Seattle and at the stores connecting with the community and growing the Tully’s brand.”

“It looks like Seattle may be my home away from home in the very near future,” he added.

Tully’s was founded in 1992 and has 46 stores in Washington and California, as well as 58 licensed locations throughout the U.S.

Dempsey may have some competition when it comes to purchasing the company, however. Early in December, Baristas Coffee Co. made an offer of $10.4 million to purchase Tully’s, according to Nation's Restaurant News.

Baristas  has been called the “Hooters of coffee” because it hires scantily clad women to pour coffee drinks, but Baristas CEO Barry Henthorn said if he were to take over Tully’s he would not try to remake it in his other chain’s image.

“Tully’s is an icon in Seattle,” he told the Seattle Post-Intelligencer.  “Tully’s will remain Tully’s.”

Tully’s will go up for a bankruptcy auction on Jan. 3.

Lakers snap Christmas Day streak with win over Knicks

Lakers 100, Knicks 94 (final)

The Lakers closed out the New York Knicks on Christmas Day to win their fifth in a row, avenging a Dec. 13 loss in New York, the low point of the season during a four-game losing streak. 

The Lakers haven't dropped a game since.

With the Lakers up by three points, Pau Gasol found a lane to the basket from the high post and flushed down a dunk to seal the victory with 11.6 seconds left.  Steve Nash, in his second game back from a leg injury, scored 16 points and dished 11 assists.

The Lakers shot 48.1% from the field but it was their defense that was instrumental in the victory, holding New York to only 16 points in the fourth quarter.

The Knicks shot 42.7% from the field despite 34 from Carmelo Anthony (13-23 shooting), who exploded in the third quarter to give the Knicks a nine-point lead.  The Lakers never led by more than five points.

Kobe Bryant also scored 34 points on 14-for-24 shooting.  Metta World Peace fouled out after scoring 20.  For the second consecutive game, Pau Gasol had six assists.

Knicks center Tyson Chandler also fouled out, finishing with six points and nine rebounds.  J.R. Smith helped carry the offensive load for New York with 25 points.

The Lakers will play on Wednesday night against the Nuggets in Denver.

Knicks 78, Lakers 77 (end of third quarter)

The Lakers survived a 17-point quarter from Carmelo Anthony to close to within one point after three quarters.

Falling behind by as many as nine points after halftime, the Lakers had a chance to go up by a point but Kobe Bryant missed a pair of free throws with 2.6 seconds left in the quarter.

Anthony climbed to 27 points for the game on 11-for-20 shooting while his Knicks shot 43.8% through three.  J.R. Smith contributed 20 points off the bench.

The Lakers were led by Bryant's 26 points on 11-for-18 shooting, while getting 18 points from Metta World Peace and 14 from Steve Nash.

Some of New York's lead was earned from behind the three-point line with eight makes in 22 tries.  The Lakers shot 48.3% from the field but only five of 18 (27.8%) from three-point range.

World Peace started the second half in place of Darius Morris but Anthony had the hot hand.

Lakers 51, Knicks 49 (halftime)

For the second consecutive quarter, the Lakers closed well against the Knicks. After New York's reserves had helped push the Knicks to a six-point advantage, the Lakers rallied to take a two-point lead at halftime.

Carmelo Anthony and Metta World Peace battled through a very physical period, challenging each other in the post. Anthony finished the half with 10 points while World Peace had a game-high 16 points after coming off the Lakers' bench.

Jessica Simpson's Christmas gift: She's pregnant

NEW YORK (AP) — Jessica Simpson's daughter has the news all spelled out: "Big Sis."

Simpson on Tuesday tweeted a photo of her baby daughter Maxwell playing in the sand, the words "Big Sis" spelled out.

The 32-year-old old singer and personality has been rumored to be expecting again. The tweet appears to confirm the rumors.

"Merry Christmas from my family to yours" is the picture's caption. Simpson used a tweet on Halloween in 2011 to announce she was pregnant with Maxwell. She is engaged to Eric Johnson and gave birth to Maxwell in May.

One possible complication regarding her pregnancy: She is a spokeswoman for Weight Watchers.

Vaulting into car history at the Petersen museum

Chris Brown's voice is giddy as the elevator in the Petersen Automotive Museum begins its descent to the basement. He is as excited as his visitors, but before the doors open he strikes a tone of caution.

"No touching, no photos and watch your step," he says. "Old cars are like little dogs: They tend to leave puddles."

The group chuckles nervously and follows him down a corridor lit by dim fluorescent lights into an enormous cavern filled with hundreds of neatly parked cars.

Brown, 38, is the museum's marketing director, but today he's exchanged suit and tie for a black racing jacket with "Petersen Museum" emblazoned in red letters on the back. Like an impresario, he faces his visitors and gestures out over the showroom, a place that has a nearly legendary status among automotive insiders around the world, a place known as the vault.

Taking up a city block on Wilshire Boulevard's Museum Row, the Petersen has drawn visitors since 1994. Its collection is considered one of the finest in the country, with detailed dioramas and presentations that provide historic and cultural context.

The vault — once restricted to high-ranking museum personnel and visiting VIPs, but now open to the public through Jan. 6 — is far different than the galleries upstairs. Inside, in a space the size of a football field, are 150 cars parked as if in a city lot. There are no special displays with manikins, velvet ropes and faux boulevards.

Many of the cars have been displayed at other times in the museum, but to see them in such simple circumstance is a chance to appreciate the swoop of a fender, the rake of a radiator grille or the grain of a leather interior.

"When you see a car upstairs," said Jay Leno, who visited the vault before its opening, "it's all polished up and roped off and everything. For a car guy like me, I prefer to walk up to a car and see it without all the pomp and circumstance."

Brown begins the hourlong tour following a clockwise pattern. To his right is a black 1952 Ferrari Barchetta once owned by Henry Ford. Behind him is the burgundy 1953 Cadillac coupe that Prince Aly Khan gave to Rita Hayworth. Herbie the Love Bug is against a far wall.

The tour group huddles in close so as not to miss a word. Stopping before a black Lincoln with undulating front fenders that hang over brilliant whitewalled tires, Brown raises a hand for dramatic effect.

"It was the first armored car ever commissioned for White House service," Brown says, his voice bouncing off the concrete walls.

Ordered the day after the attack on Pearl Harbor for President Franklin D. Roosevelt, the 1942 Lincoln was built with steel plating nearly a quarter-inch thick and has windows made up of nine panes of laminated glass.

Craig Parry, visiting from Morganville, Kan., is impressed. He is with his wife, Terri, and their son David. They hadn't intended to visit the vault but thought it would be an opportunity to see history. Crossing his arms, he looks out over the collection.

"I've never seen or heard of many of the cars they have here," Parry said. "We got lucky."

At a time when museums across the country are struggling to boost attendance, Petersen officials know the value of their collection and are eager to capitalize on any aspect of it that might increase the visitor count.

Terry Karges came up with the idea of marketing the vault (tours cost $25 on top of the museum's $12 admission fee). He is the executive director of the Petersen, and when he was hired in August he realized that he had a challenge. There was a time when Petersen officials hoped to draw 400,000 visitors a year. At best, the museum has succeeded in drawing half that number. Karges believes the problem has been underexposure.

"The Petersen is largely considered to be the crown jewel of automotive museums," he said. "You just stand back and say, 'There's so much more we can do to attract people.'"

Automobile museums are a hard sell.

"All museums have to get creative to bring in those crowds — whether that's a new exhibit, or opening the vault, whatever," said Jackie L. Frady, executive director of the National Automobile Museum in Reno and president of the National Assn. of Automobile Museums.

In Reno, Frady oversaw an exhibit that featured a group of wild cars from the Burning Man festival, including one automobile that resembled a plump baked potato and another that looked like two matching pink bunny slippers.

Dueling Santa trackers are off and running

A screen grab from Google's Santa Tracker. (Google / December 24, 2012)

By Deborah Netburn

December 24, 2012, 1:11 p.m.

All year long Santa keeps an eye on you. Now it's time to turn the tables.

One day a year, you are invited to keep an eye on Santa as he whips around the world in his sleigh, delivering a dizzying number of presents to children all over the world.

If you'd like to see where Santa is at the moment, you've got choices. Google and NORAD, which used to team up for your Santa tracking pleasure, have gone their separate ways this year and created two distinct tracking options.

Google's Santa Tracker is the slicker of the two. It takes you to Santa's Dashboard, where you can see Santa's current location, his next location, the number of miles traveled, and the number of presents delivered. Santa is also adding Twitter like status updates. The most recent one as of this writing: "Rudolph's nose just turned red." 

PHOTOS: Google Doodles of 2012

You can also click on the map and see where Santa has been, as noted by little present icons on the map. Click on the icon and you'll see how many presents Santa has delivered in each city. When Santa is on the move, you'll see him flying on the map in a sleigh. When he's stopped to deliver presents, you'll see him shoving presents down a chimney.

Over at the official NORAD Tracks Santa website you'll also find a running tally of how many presents Santa has delivered as well as what city he just left and what city he's currently headed toward. NORAD also offers Santa Cams that show animations of Santa flying around the world. 

Both Santa tracking services offer loads of extras. If you visit Santa's Village on Google's tracker you can send a message from  Santa to a friend or family member. And NORAD has more than 1,200 volunteers staffing a Santa hotline to answer all your Santa questions.  (877-HI-NORAD).

In the spirit of the season you might try them both out, but hurry up. The trackers shut down a few hours before Christmas morning. 

Happy tracking!

Thousands sign US petition to deport Piers Morgan

LONDON (AP) — Tens of thousands of people have signed a petition calling for British CNN host Piers Morgan to be deported from the U.S. over his gun control views.

Morgan has taken an aggressive stand for tighter U.S. gun laws in the wake of the Newtown, Connecticut, school shooting. Last week, he called a gun advocate appearing on his "Piers Morgan Tonight" show an "unbelievably stupid man."

Now, gun rights activists are fighting back. A petition created Dec. 21 on the White House e-petition website by a user in Texas accuses Morgan of engaging in a "hostile attack against the U.S. Constitution" by targeting the Second Amendment. It demands he be deported immediately for "exploiting his position as a national network television host to stage attacks against the rights of American citizens."

The petition has already hit the 25,000 signature threshold to get a White House response. By Monday, it had 31,813 signatures.

Morgan seemed unfazed — and even amused — by the movement.

In a series of Twitter messages, he alternately urged his followers to sign the petition and in response to one article about the petition said "bring it on" as he appeared to track the petition's progress.

"If I do get deported from America for wanting fewer gun murders, are there any other countries that will have me?" he wrote.

News Analysis: Getting Polio Campaigns Back on Track

How in the world did something as innocuous as the sugary pink polio vaccine turn into a flash point between Islamic militants and Western “crusaders,” flaring into a confrontation so ugly that teenage girls — whose only “offense” is that they are protecting children — are gunned down in the streets?

Nine vaccine workers were killed in Pakistan last week in a terrorist campaign that brought the work of 225,000 vaccinators to a standstill. Suspicion fell immediately on factions of the Pakistani Taliban that have threatened vaccinators in the past, accusing them of being American spies.

Polio eradication officials have promised to regroup and try again. But first they must persuade the killers to stop shooting workers and even guarantee safe passage.

That has been done before, notably in Afghanistan in 2007, when Mullah Muhammad Omar, spiritual head of the Afghan Taliban, signed a letter of protection for vaccination teams. But in Pakistan, the killers may be breakaway groups following no one’s rules.

Vaccination efforts are also under threat in other Muslim regions, although not this violently yet.

In Nigeria, another polio-endemic country, the new Islamic militant group Boko Haram has publicly opposed it, although the only killings that the news media have linked to polio were those of two police officers escorting vaccine workers. Boko Haram has killed police officers on other missions, unrelated to polio vaccinations.

In Mali, extremists took over half of the country in May, declaring an Islamic state. Vaccination is not an issue yet, but Mali had polio cases as recently as mid-2011, and the virus sometimes circulates undetected.

Resistance to polio vaccine springs from a combination of fear, often in marginalized ethnic groups, and brutal historical facts that make that fear seem justified. Unless it is countered, and quickly, the backlash threatens the effort to eradicate polio in the three countries where it remains endemic: Pakistan, Afghanistan and Nigeria.

In 1988, long before donors began delivering mosquito nets, measles shots, AIDS pills, condoms, deworming drugs and other Western medical goods to the world’s most remote villages, Rotary International dedicated itself to wiping out polio, and trained teams to deliver the vaccine.

But remote villages are often ruled by chiefs or warlords who are suspicious not only of Western modernity, but of their own governments.

The Nigerian government is currently dominated by Christian Yorubas. More than a decade ago, when word came from the capital that all children must swallow pink drops to protect them against paralysis, Muslim Hausas in the far-off north could be forgiven for reacting the way the fundamentalist Americans of the John Birch Society did in the 1960s when the government in far-off Washington decreed that, for the sake of children’s teeth, all drinking water should have fluoride.

The northerners already had grievances. In 1996, the drug company Pfizer tested its new antibiotic, Trovan, during a meningitis outbreak there. Eleven children died. Although Pfizer still says it was not to blame, the trial had irregularities, and last year the company began making payments to victims.

Other rumors also spring from real events.

In Pakistan, resistance to vaccination, low over all, is concentrated in Pashtun territory along the Afghan border and in Pashtun slums in large cities. Pashtuns are the dominant tribe in Afghanistan but a minority in Pakistan among Punjabis, Sindhis, Baluchis and other ethnic groups. Many are Afghan refugees and are often poor and dismissed as medieval and lawless.

Pakistan’s government is friendly with the United States while the Pashtuns’ territory in border areas has been heavily hit by American Taliban-hunting drones, which sometimes kill whole families.

So, when the Central Intelligence Agency admitted sponsoring a hepatitis vaccination campaign as a ruse to get into a compound in Pakistan to confirm that Osama bin Laden was there, and the White House said it had contemplated wiping out the residence with a drone missile, it was not far-fetched for Taliban leaders to assume that other vaccinators worked for the drone pilots.

Even in friendly areas, the vaccine teams have protocols that look plenty suspicious. If a stranger knocked on a door in Brooklyn, asked how many children under age 5 were at home, offered to medicate them, and then scribbled in chalk on the door how many had accepted and how many refused — well, a parent might worry.

In modern medical surveys — though not necessarily on polio campaigns — teams carry GPS devices so they can find houses again. Drones use GPS coordinates.

The warlords of Waziristan made the connection specific, barring all vaccination there until Predator drones disappeared from the skies.

Dr. Bruce Aylward, a Canadian who is chief of polio eradication for the World Health Organization, expressed his frustration at the time, saying, “They know we don’t have any control over drone strikes.”

The campaign went on elsewhere in Pakistan — until last week.

The fight against polio has been hampered by rumors that the vaccine contains pork or the virus that causes AIDS, or is a plot to sterilize Muslim girls. Even the craziest-sounding rumors have roots in reality.

The AIDS rumor is a direct descendant of Edward Hooper’s 1999 book, “The River,” which posited the theory — since discredited — that H.I.V. emerged when an early polio vaccine supposedly grown in chimpanzee kidney cells contaminated with the simian immunodeficiency virus was tested in the Belgian Congo.

The sterilization claim was allegedly first made on a Nigerian radio station by a Muslim doctor upset that he had been passed over for a government job. The “proof” was supposed to be lab tests showing it contained estrogen, a birth control hormone.

The vaccine virus is grown in a broth of live cells; fetal calf cells are typical. They may be treated with a minute amount of a digestive enzyme, trypsin — one source of which is pig pancreas, which could account for the pork rumor.

In theory, a polio eradicator explained, if a good enough lab tested the vaccine used at the time the rumor started, it might have detected estrogen from the calf’s mother, but it would have been far less estrogen than is in mother’s milk, which is not accused of sterilizing anyone. The trypsin is supposed to be washed out.

In any case, polio vaccine is now bought only from Muslim countries like Indonesia, and Muslim scholars have ruled it halal — the Islamic equivalent of kosher.

Reviving the campaign will mean quelling many rumors. It may also require adding other medical “inducements,” like deworming medicine, mosquito nets or vitamin A, whose immediate benefits are usually more obvious.

But changing mind-sets will be a crucial step, said Dr. Aylward, who likened the shootings of the girls to those of the schoolchildren in Newtown, Conn.

More police involvement — what he called a “bunkerized approach” — would not solve either America’s problem or Pakistan’s, he argued. Instead, average citizens in both countries needed to rise up, reject the twisted thinking of the killers and “generate an understanding in the community that this kind of behavior is not acceptable.”
