Ricardo Orrego y el Analfabetismo Digital.

Mención frecuente tiene la palabra tecnología dentro de los escenarios propios de telecomunicaciones, información y despliegue multimedia. El ejemplo de hoy nos remite a preguntas que parecen casi inconexas con el Mundial de Fútbol de Brasil 2014: ¿por qué esa vocación de personajes ancianos (no proclives al aprendizaje) para descalificar recursos informáticos evadiendo su propia torpeza? ¿Cuántas veces vamos a escuchar a un experto deportivo, académico o político evadir la crítica personal o escaparse a responder ¨no sé¨ o ¨me equivoqué¨? ¿Hasta qué punto sustentamos nuestro periodismo en lugares comunes de conversaciones vacías como la pertinencia de ese algo distinto intitulado tecnología?

Un problema elemental de comprensión de lectura digital describe la diatriba de seis comentarios de Ricardo Orrego cuestionando el segundo gol de Francia en su partido inaugural frente a Honduras. No leer un texto completo u observar en su totalidad un paquete de información son déficits razonables en los primeros años de educación escolar media. Fundar una exposición en un medio masivo de información (Caracol TV, con el rating del Mundial de Fútbol) en un error de análisis de información propio en salones de clase con preadolescentes nos recuerda cuán pertinente vuelve a ser reforzar habilidades ínfimas escolares antes de proporcionar un micrófono y salario a un personaje tan elemental como Ricardo.


How to Fix OS X Mavericks’ Biggest Annoyances

How to Fix OS X Mavericks\’ Biggest Annoyances


Everything You Need to Know About OS X Mavericks In Four Minutes

OS X Mavericks is coming today for free, and while there aren\’t that many new features this time around, it still has a few new tricks up its… Read…

OS X Mavericks was released yesterday, and while it\’s hard to complain too much about a free operating system, there\’s a few things Mavericks does that might get your goat. Here\’s how to fix those annoyances.P

Re-Enable Your Favorite Text ExpanderP

Most text expansion programs work by enabling a special accessibility option in the settings. That option was moved in OS X Mavericks, so there\’s a good chance your text expander of choice has suddenly stopped working. Thankfully, the fix is relatively easy:P

Open System Preferences.

Select Privacy & Security.

Click the Privacy Tab.

Select Accessibility.

Click the lock button and enter your password.

If you text expander is listed here, make sure the box next to it is checked. If not, open up your Applications folder and drag the icon to the System Preferences box.

Once your text expander is listed you should have no problem getting it to work properly. If you\’re using any similar tools that tap into Accessibility options like BetterTouchTool you\’ll need to do run through the same process.P

Disable Notification Center on the Lock ScreenP

Notification Center doesn\’t see a whole lot of improvement this time around, but the update does mess with your settings a little bit. If you\’re not a fan of getting a million notifications, you\’re going to want to pop into System Preferences > Notifications and take a look at the new options. The big one to check is \”Show notifications on lock screen.\” If you don\’t want your emails or anything else showing when you\’re computer is locked, uncheck this box.P

Disable Automatic App UpdatesP

Auto updates aren\’t new to OS X, but Mavericks handles them a bit differently than Mountain Lion did. This time around they happen in the background. The good news is you\’re offered a bit more control of what\’s updated.P

Head into System Preferences > App Store. Here you can turn off automatic updates or fine tune how they\’re handled. If you don\’t like the idea of just downloading every updated imaginable, it\’s a good idea to turn these off.P

Enable Offline DictationP


How to Talk to Your Mac: Using Dictation Effectively

One of the more useful and interesting features in OS X Mountain Lion is Dictation, which allows you to speak to your Mac and have your words… Read…

Dictation was introduced in Mountain Lion, but it required an internet connection to work. Since you can\’t always be connected, Mavericks allows you to download the dictation software so you can use it offline.P

Head to System Preferences > Dictation & Speech and check the \”Use Enhanced Dictation\” box. This enabled the ability to use dictation regardless of whether you have an internet connection or not.P

Prevent App Nap On Select AppsP

App Nap is the new system in Mavericks that helps save power and increase battery life. If an app\’s not currently doing anything, App Nap conserves battery life by slowing the app down. In most cases, this is good when you\’re working off a laptop, but if you find yourself in a special circumstance where you want to disable it on a per-app basis, you can. Just right-click an app and select \”Get Info.\” Then check the box labeled \”Prevent App Nap.\”P

Download Adobe Flash and Java RuntimeP

Mavericks doesn\’t come packed with two pieces of software you\’ll probably need at some point, Flash and Java. In fact, if you had either installed in OS X Mountain Lion, Apple went ahead and deleted it when you upgraded to Mavericks. Here\’s how to install Java:P

Open up Terminal (Applications > Utilities) and type:

java -version

If Java isn\’t installed, you\’ll see an option to download it. If it is, you\’ll see something similar to the screenshot above. Click the \”More info\” buttons. Find the file for Mavericks, then download and install it.

You\’ll need Java for all kinds of apps, from FTP clients to Minecraft servers, so it\’s not a bad idea to download it right away.P

Likewise, Apple deleted that copy of Adobe Flash you\’d installed before the updated. If you\’re having trouble playing any Flash content, head over to Adobe and re-download the plugin again.P

Check for App UpdatesP

We\’ve had pretty good luck with app compatibility in OS X Mavericks, but if you\’re having trouble you\’ll want to make sure you update your software. You can do this either by heading to Apple logo > Software Update, or through your software\’s own update system. If you want to double-check software compatibility before you make the upgrade, head over to Roaring Apps and search for your software of choice.P

Mars Curiosity rover’s Top 5 discoveries

NASA’s Curiosity rover has already made a number of remarkable discoveries in just seven months on Mars. Here’s a “Top Five” list:

— Chemicals of life: NASA announces Tuesday that analysis of a Martian rock finds chemistry that could have once supported living things on the Red Planet.

— Once-habitable environment: More than three billion years ago, relatively freshwater flowed over clay lake beds packed with minerals useful for biochemistry, inside Gale Crater, where the rover now roams.

— Gray Mars: The drill on the rover revealed sub-surface conditions on Mars that point to distinctly different coloration for the Red Planet in the past. Instead of the ubiquitous ruddy dust now coating the planet, a mudstone gray appears to have carpeted the floor of Gale Crater.

— Aloha, Mars: An X-ray spectrum analysis of the surface dust on Mars finds that chemically it resembles the basaltic lava spewed from Hawaii’s volcanoes. The find points to volcanic origins for the dust.

STORY: Life on Mars? Rover shows it could’ve been possible

— Astronaut hazards: Radiation monitoring sensors on the rover have confirmed that radiation on the Martian surfaces rivals conditions in interplanetary space, important knowledge for the safety of future explorers.

Harvard professor who resigned fabricated, manipulated data, US says – Boston Medical News – White Coat Notes – Boston.com

By Carolyn Y. Johnson, Globe Staff

Marc Hauser, a prolific scientist and popular psychology professor who last summer resigned from Harvard University, had fabricated data, manipulated results in multiple experiments, and described how studies were conducted in factually incorrect ways, according to the findings of a federal research oversight agency posted online Wednesday.

‘Organic’ a waste of money? Depends on your reason for buying it – latimes.com

‘Organic’ a waste of money? Depends on your reason for buying it





Gayle King speaks with registered dietitian Samantha Heller about a new study that says organically grown food is not more nutritious than non-organic foods.

By Rene Lynch

September 4, 2012, 12:20 p.m.

The American public has been hammered for years by seemingly everyone from First Lady Michelle Obama to Dr. Oz that buying organic produce is the way to go. Many of us have dutifully complied, even as it left a sizable dent in our bank account.

Now a new study suggests that buying organic might not be worth the money. The research, out of Stanford University, found that organic produce isn’t necessarily healthier than more conventional produce.

Consumers might well ask: Can’t all you “experts” with your fancy degrees and titles agree on anything?

Further, although the study found that organic produce carried fewer pesticides, the levels detected in the conventionally grown produce were well within federally established safety guidelines, the study says.

The upshot? “There isn’t much difference between organic and conventional foods, if you’re an adult and making a decision based solely on your health,” study senior author Dr. Dena Bravata of Stanford’s Center for Health Policy said in a university statement.

Instead of clarifying the issue of organics for the public, this latest study might complicate it, with some saying that  the findings miss the point and actually pose a red herring for consumers. 

One of the most recognized voices in this arena, author Michael Pollan, tweeted that nutritional questions are not necessarily the reason for the “buy organic” movement. There’s a long list of reasons to go organic, including limiting exposure to pesticides and a way of farming that is more environmentally friendly. (The Atlantic posted a reaction piece online titled “Organic Food Isn’t More Nutritious, But That Isn’t the Point.”)

Take the temperature over on Twitter, and you’ll find many blaming not just the study but the media as well for allegedly distorting the study’s findings with an overly negative headline and stories that miss the nuance. 

Our sister blog, Booster Shots, delved further into the study published in the Annals of Internal Medicine, and its findings.

The study is only the latest in a long list of seemingly contradictory health news, made more confusing by the media’s desire to boil months and years of research into a single headline.

One day, coffee is good for you, the next it’s bad. One day eggs are good for you, the next day egg yolks are right up there with smoking(!).

One finding that we won’t argue with: that fried food isn’t always bad for you — especially when that chicken is fried in heart-friendly olive oil or sunflower oil.

Full transcript of Julian Assange’s speech outside Ecuador’s London embassy – Home News – UK – The Independent

“Can you hear me?

“I am here today because I cannot be there with you today. But thank you for coming. Thank you for your resolve and your generosity of spirit.

“On Wednesday night, after a threat was sent to this embassy and the police descended on this building, you came out in the middle of the night to watch over it and you brought the world’s eyes with you.

“Inside this embassy, after dark, I could hear teams of police swarming up into the building through its internal fire escape. But I knew there would be witnesses. And that is because of you.

“If the UK did not throw away the Vienna conventions the other night, it is because the world was watching. And the world was watching because you were watching.

“So, the next time somebody tells you that it is pointless to defend those rights that we hold dear, remind them of your vigil in the dark before the Embassy of Ecuador.

“Remind them how, in the morning, the sun came up on a different world and a courageous Latin America nation took a stand for justice.

And so, to those brave people. I thank President Correa for the courage he has shown in considering and in granting me political asylum.

“And I also thank the government, and in particular Foreign Minister Ricardo Patino, who upheld the Ecuadorian constitution and its notion of universal rights in their consideration of my asylum. And to the Ecuadorian people for supporting and defending this constitution.

“And I also have a debt of gratitude to the staff of this embassy, whose families live in London and who have shown me the hospitality and kindness despite the threats we all received.

“This Friday, there will be an emergency meeting of the foreign ministers of Latin America in Washington DC to address this very situation.

“And so, I am grateful to those people and governments of Argentina, Bolivia, Brazil, Chile, Columbia, El Salvador, Honduras, Mexico, Nicaragua, Argentina, Peru, Venezuela, and to all other Latin American countries who have come out to defend the right to asylum.

“And to the people of the United States, United Kingdom, Sweden and Australia who have supported me in strength, even when their governments have not. And to those wiser heads in government who are still fighting for justice. Your day will come.

“To the staff, supporters and sources of Wikileaks, whose courage and commitment and loyalty has seen no equal.

“To my family and to my children who have been denied their father. Forgive me, we will be reunited soon.

“As Wikileaks stands under threat, so does the freedom of expression and the health of all our societies. We must use this moment to articulate the choice that is before the government of the United States of America.

“Will it return to and reaffirm the values, the revolutionary values it was founded on, or will it lurch off the precipice dragging us all into a dangerous and oppressive world, in which journalists fall silent under the fear of prosecution and citizens must whisper in the dark?

“I say it must turn back. I ask President Obama to do the right thing. The United States must renounce its witch-hunts against Wikileaks. The United States must dissolve its FBI investigation.

“The United States must vow that it will not seek to prosecute our staff or our supporters. The United States must pledge before the world that it will not pursue journalists for shining a light on the secret crimes of the powerful.

“There must be no more foolish talk about prosecuting any media organisation; be it Wikileaks, or be it the New York Times.

“The US administration’s war on whistleblowers must end.

“Thomas Drake, William Binney and John Kirakou and the other heroic whistleblowers must – they must – be pardoned or compensated for the hardships they have endured as servants of the public record.

“And to the Army Private who remains in a military prison in Fort Leavenworth, Kansas, who was found by the United Nations to have endured months of torturous detention in Quantico, Virginia and who has yet – after two years in prison – to see a trial: he must be released.

“Bradley Manning must be released.

“And if Bradley Manning did as he is accused, he is a hero and an example to us all and one of the world’s foremost political prisoners.

“Bradley Manning must be released.

“On Wednesday, Bradley Manning spent his 815th day of detention without trial. The legal maximum is 120 days.

“On Thursday, my friend Nabeel Rajab, President of the Bahrain Human Rights Centre, was sentenced to three years in prison for a tweet. On Friday, a Russian band were sentenced to two years in jail for a political performance.

“There is unity in the oppression. There must be absolute unity and determination in the response.

“Thank you.”
