Protagonistas 2.0

Hoy, Enrique Dans.



Enrique Dans, gallego afincado en Madrid, es, entre otras muchas
cosas, Doctor en Sistemas de Información por la Universidad de
California y profesor de Sistemas y Tecnologías de Información en
la IE Business School. Su figura, una de las más influyentes dentro
del panorama de la Web 2.0, su blog (y esto lo digo presa de una
malsana envidia), uno de los más visitados de nuestro país, le
convierten en el candidato idóneo para inaugurar esta sección
de protagonistas del mundo cibernético.


Buenos días, Enrique, ante todo gracias por acceder a contestar
estas preguntas, ¿comenzamos?

La palabra gurú suele aplicarse a personas que han marcado
algún tipo de tendencia con su pensamiento sobre un tema
determinado. Tiene una connotación casi religiosa, y no creo que
sea en absoluto apropiado aplicársela a alguien como yo. Yo soy un
simple profesor que disfruta con su trabajo y que intenta compartir
muchas de las cosas que aprende en el desempeño del mismo. Muchas
de esas cosas las comparto en la red desde hace ya mucho tiempo y
con un nivel de constancia elevado porque el desarrollo del blog
está muy integrado con mi trabajo de todos los días, y la red tiene
una característica importante: suele traerte lo mismo que pones en
ella, en edición corregida y mejorada. Si en la red pones
contenidos interesantes, la red te trae más contenidos
interesantes, de ahí que el blog me sirva habitualmente para
preparar mis clases y conferencias, escribir mis columnas de
prensa, etc.






En absoluto. Son muy pocos comparativamente, y se cansan
siempre en seguida, no me aguanta ninguno ni medio asalto

Marusys MS630S and MS850S set-top boxes stream straight to your iPhone

If you didn't already have enough ways to get content onto your iPhone, Marusys is adding two more to the pile with its MS630S and MS850S set-top boxes. Said to be PVR-ready, these boxes are designed to serve up content in all sorts of ways, with composite, component, and HDMI video outputs on the back and, inside, the ability to run Linux-based media players like XBMC. Both rock a Magnum DX6225 media chip, enabling on-the-fly transcoding of content into a variety of formats, including the hallmark feature of these devices: streaming straight to the iPhone over WiFi. It's not exactly clear how this will work as Marusys itself doesn't explain this functionality on its site, but Magnum certainly talks it up in the press release after the break. No word on price and availability of either, or when we might get more info on how this whole thing fits together, but you can be sure you'll know as soon as we do.

Samsung mejora la performance de sus tarjetas de memoria MicroSD

Samsung mejora la performance de sus tarjetas de memoria MicroSD: "

Samsung acaba de lanzar un comunicado de prensa oficial para anunciar que son la primera compañía de la industria en producir chips NAND de 20 nanometer (nm) class, los cuales se utilizan en tarjetas MicroSD.


Basados en esta tecnología se espera que Samsung expanda sus soluciones de tarjetas de memoria con una nueva tarjeta MicroSD de 32GB MLC NAND.

“En sólo 1 año desde que iniciamos la producción de 30nm-class NAND production, Samsung pone disponibles la nueva generación de 20nm-class NAND, la cual excede los requerimientos de la mayoría de los clientes para alta performance, con soluciones basadas en NAND de alta densidad”, explicaron en el press release.


La innovación en performance que ofrecen este nuevo tipo de tarjetas microSD significaría un aumento del 50% en el nivel de productividad frente a la tecnología anterior. Samsung Electronics empezó a producir tarjetas de memoria de 32GB NAND con la tecnología 30nm-class en marzo de 2009 y ahora está enviando tarjetas de prueba a los clientes que están construidas con el nuevo 20nm-class 32GB NAND con la idea de expandir la producción más tarde este año.


Se espera que las tarjetas de memoria microSD basadas en 20nm-class estén disponibles desde los 4GB hasta los 64GB.

Seguridad por un tubo

Seguridad por un tubo: "Desde que youtube sobrepasara a todas las webs de descarga y
visualización de videos, toda web que se precie que de un servicio de
vídeos tiene que tener el sufijo “tube” así, tenemos el pornotube, el
redtube...



Además de esos tipos de vídeos, una forma de
autoformarse en seguridad es asistir a las conferencias de seguridad de
todo el mundo a través de webs de distribución de vídeos. La mayoría de
las conferencias graban las sesiones y, en la web de SecurityTube.NET, se intentan
recoger de todos los sitios, guardar y catalogar. Esto permite que
cualquiera pueda asistir a la ShmooCon 2010, a la BlackHat o, incluso, a
la BlueHat de Spectra.

puedes parar y ver en varias veces, probar al mismo tiempo que ves la
charal y repetirlo hasta que lo entiendas bien… y si es aburrida… Fast
Forward, que esto no lo puedes hacer en la vida real. }:)

XAuth: One Share Button to Rule Them All?

XAuth: One Share Button to Rule Them All?: "

Have you ever visited a website (like, say, this one) and been bombarded with share buttons from sites like Twitter, Facebook and Google Buzz and login options for Facebook Connect, Google Friend Connect, Yahoo, Twitter and more?

A new proposed standard from IM and toolbar company Meebo hopes to solve this “Nascar problem” (i.e. logos everywhere) by detecting which networks you’re already logged into and only offering those as options.

Tonight Meebo is announcing the proposed standard, called XAuth (Extended Authentication), the New York Times and VentureBeat report. It’s not really a single login, but instead a way of offering only the login options that are relevant to you. Meebo is putting XAuth into its Meebo bar, which appears on a number of publisher websites. Robert Scoble of Building43 interviewed Meebo CEO Seth Sternberg about the plans — you can see the video below.

Who’s on board? Google, Microsoft, Yahoo, MySpace and Disqus, to name a few.

But there’s a big problem: Twitter and Facebook don’t appear to support XAuth yet. That means, rather than uniting these sharing services, the runner-up services are all banding together. That doesn’t simplify things for users or publishers.

And Facebook is unlikely to play along, as the company would much rather dominate the sharing space. On Wednesday at the F8 conference, Facebook will launch a product that aims to spread its “Like” button across the entire web. Facebook will also launch a website toolbar, reports The Times, hoping to kill off Meebo’s share bar.

While we love open standards and user choice, the smart money is on Facebook here. To the average user, one choice (Facebook) is much simpler than a handful of lesser-known services.

Controversial content and free expression on the web: a refresher

Controversial content and free expression on the web: a refresher: "Two and a half years ago, we outlined our approach to removing content from Google products and services. Our process hasn’t changed since then, but our recent decision to stop censoring search on Google.cn has raised new questions about when we remove content, and how we respond to censorship demands by governments. So we figured it was time for a refresher.



Censorship of the web is a growing problem. According to the Open Net Initiative, the number of governments that censor has grown from about four in 2002 to over 40 today. In fact, some governments are now blocking content before it even reaches their citizens. Even benign intentions can result in the specter of real censorship. Repressive regimes are building firewalls and cracking down on dissent online -- dealing harshly with anyone who breaks the rules.



Increased government censorship of the web is undoubtedly driven by the fact that record numbers of people now have access to the Internet, and that they are creating more content than ever before. For example, over 24 hours of video are uploaded to YouTube every minute of every day. This creates big challenges for governments used to controlling traditional print and broadcast media. While everyone agrees that there are limits to what information should be available online -- for example child pornography -- many of the new government restrictions we are seeing today not only strike at the heart of an open Internet but also violate Article 19 of the Universal Declaration of Human Rights, which states that: “Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers.”



We see these attempts at control in many ways. China is the most polarizing example, but it is not the only one. Google products -- from search and Blogger to YouTube and Google Docs -- have been blocked in 25 of the 100 countries where we offer our services. In addition, we regularly receive government requests to restrict or remove content from our properties. When we receive those requests, we examine them to closely to ensure they comply with the law, and if we think they’re overly broad, we attempt to narrow them down. Where possible, we are also transparent with our users about what content we have been required to block or remove so they understand that they may not be getting the full picture.



On our own services, we deal with controversial content in different ways, depending on the product. As a starting point, we distinguish between search (where we are simply linking to other web pages), the content we host, and ads. In a nutshell, here is our approach:



Search is the least restrictive of all our services, because search results are a reflection of the content of the web. We do not remove content from search globally except in narrow circumstances, like child pornography, certain links to copyrighted material, spam, malware, and results that contain sensitive personal information like credit card numbers. Specifically, we don’t want to engage in political censorship. This is especially true in countries like China and Vietnam that do not have democratic processes through which citizens can challenge censorship mandates. We carefully evaluate whether or not to establish a physical presence in countries where political censorship is likely to happen.



Some democratically-elected governments in Europe and elsewhere do have national laws that prohibit certain types of content. Our policy is to comply with the laws of these democratic governments -- for example, those that make pro-Nazi material illegal in Germany and France -- and remove search results from only our local search engine (for example, www.google.de in Germany). We also comply with youth protection laws in countries like Germany by removing links to certain material that is deemed inappropriate for children or by enabling Safe Search by default, as we do in Korea. Whenever we do remove content, we display a message for our users that X number of results have been removed to comply with local law and we also report those removals to chillingeffects.org, a project run by the Berkman Center for Internet and Society, which tracks online restrictions on speech.



Platforms that host content like Blogger, YouTube, and Picasa Web Albums have content policies that outline what is, and is not, permissible on those sites. A good example of content we do not allow is hate speech. Our enforcement of these policies results in the removal of more content from our hosted content platforms than we remove from Google Search. Blogger, as a pure platform for expression, is among the most open of our services, allowing for example legal pornography, as long as it complies with the Blogger Content Policy. YouTube, as a community intended to permit sharing, comments, and other user-to-user interactions, has its Community Guidelines that define its own rules of the road. For example, pornography is absolutely not allowed on YouTube.



We try to make it as easy as possible for users to flag content that violates our policies. Here’s a video explaining how flagging works on YouTube. We review flagged content across all our products 24 hours a day, seven days a week to remove offending content from our sites. And if there are local laws where we do business that prohibit content that would otherwise be allowed, we restrict access to that content only in the country that prohibits it. For example, in Turkey, videos that insult the founder of modern Turkey, Mustafa Ataturk, are illegal. Two years ago, we were notified of such content on YouTube and blocked those videos in Turkey that violated local law. A Turkish court subsequently demanded that we block them globally, which we refused to do, arguing that Turkish law cannot apply outside Turkey. As a result YouTube has been blocked there.



Finally, our ads products have the most restrictive policies, because they are commercial products intended to generate revenue.



These policies are always evolving. Decisions to allow, restrict or remove content from our services and products often require difficult judgment calls. We have spirited debates about the right course of action, whether it’s about our own content policies or the extent to which we resist a government request. In the end, we rely on the principles that sit at the heart of everything we do.



We’ve said them before, but in these particularly challenging times, they bear repeating: We have a bias in favor of people's right to free expression. We are driven by a belief that more information means more choice, more freedom and ultimately more power for the individual.
