Pek çok ülke internet erişimini kısıtlıyor. Özellikle bu kısıtlamalar ülkemizde gün geçtikçe artıyor. Yurtiçi ya da yurtdışı pek çok internet sitesine şu anda erişim engellenmiş durumda. Bazı sitelere DNS değiştirerek bile erişim sağlayamayabiliyoruz.

Bizim bu yazımızdaki konumuzda inadına açılmayan sitelere girmek. Anlatacağımız yöntem ile yasaklı tüm sitelere, bilgisayarınızın tarayıcısından normal bir siteye giriyormuş gibi girebileceksiniz.

Cómo acceder a una discoteca digital casi infinita desde la Argentina

Servicios como Spotify o Pandora sólo están disponibles en Estados Unidos o Europa, pero un truco informático permite saltar la barrera geográfica

Por Guillermo Tomoyose  | LA NACION

Durante la cobertura del Google I/O en San Francisco pude descubrir que, a pesar de su naturaleza, Internet no es tan libre ni se comporta de la misma forma en todo el mundo. Cuando accedía a la Red desde el Wi-Fi del hotel, sitios como Facebook detectaban mi ubicación geográfica y me obligaban (por razones de seguridad) a verificar el nombre de mis amigos mediante fotos para comprobar si efectivamente era yo, en Estados Unidos, quien accedía a mi perfil argentino en esa red social. No soy el único: todos hemos sufrido, alguna situación similar, desde la comprobación de la cuenta de correo hasta la imposibilidad de acceder a un videoclip, canción o película on line por limitaciones de licencias regionales.

¿Cómo puede ser posible esto? Con un mayor o menor grado de sofisticación, nuestra localización queda delatada por el número IP , el identificador único que cada usuario recibe cuando se conecta a Internet que, asociado a la ubicación geográfica, permite que determinados servicios detecten nuestra ubicación y limiten su servicio en función de las licencias que tienen en cada país.

Esto ocurre a menudo en YouTube, y en particular con los contenidos de Vevo. Por ejemplo, el perfil oficial de Jason Aldean , un solista estadounidense de música country, no ofrece lo mismo según la ubicación geográfica. Por supuesto, tal vez no haya un público demasiado interesado en ver el videclip oficial de Amarillo Sky en la Argentina, pero ese no es el punto. (Si se quedaron con la duda, pueden ver el clip por aquí , hasta que Content ID lo remueva)

 

De a poco, en este y otros ejemplos, se advierte la paulatina segmentación que vive Internet en cuanto a los contenidos, en donde no todos pueden ver o acceder a lo mismo. No es algo que nos sorprenda, ni será la primera vez que ocurra.¿Qué hubiera pasado si un ignoto cantante coreano llamado Psy hubiese puesto sus limitaciones geográficas al famoso videoclip del paso del caballo? ¿O si los hijos del Tano Pasman hubiesen restringido la reproducción de los insultos en otras partes del mundo?

Por fortuna, la fuerza de Internet trasciende mucho más allá de estos límites irritantes que imponen los dueños de los contenidos en Internet.

Hombre grande, ¿era necesario? 🙂

Un atajo para evitar las restricciones geográficas

Esto se replica en plataformas online de videojuegos y tiendas de aplicaciones. ¿Acaso mi dinero no vale? Depende de dónde viva , sería la respuesta del cantinero imaginario.

IntoNow , considerada una excelente aplicación para identificar series (algo así como el Shazam de la TV) sólo se encuentra disponible en Estados Unidos.

Lo mismo pasa con Hulu, una plataforma online gratuita de películas sustentada en avisos publicitarios o Pandora, una radio online que configura las estaciones de acuerdo a nuestras preferencias.

Sin embargo, quien se lleva toda la atención es Spotify , que se convirtió en la opción predilecta para los amantes de la música. En su versión gratis, la plataforma sueca que arribó al mercado estadounidense permite establecer un acceso ilimitado en streaming a un amplio catálogo de artistas de todo el mundo, patrocinado con eventuales avisos publicitarios, que se pueden evitar si uno se suscribe a un plan mensual.

No obstante, todo esto es posible si uno se encuentra conectado a Internet desde Estados Unidos. En la Argentina Sonora apunta a ofrecer un servicio similar , lo mismo que Taringa y otras alternativas gratis como Grooveshark , pero todas más limitadas en su catálogo. Por fortuna, existen atajos que permiten estar fuera de Estados Unidos y aún así usar Spotify, apelando a una VPN, un servicio de conexión a redes privadas que permite el acceso a estos servicios.

Si bien hay una gran cantidad de alternativas sin costo que permiten emular en Internet nuestra presencia en otro país, sus limitaciones (otra vez) hacen que pagar por este tipo de prestaciones sea la mejor alternativa.

Por mencionar sólo algunos servicios, StrongVPN y Hide My Ass! (curioso nombre para un servicio de Internet) permiten disfrutar de Spotify, Pandora o Hulu, entre otros, sin mayores problemas. Como ocurre con la mayoría de los casos, lograrlo requiere tener una comprensión básica de inglés y algo de maña al momento de realizar la configuración de la conexión de VPN, que es muy flexible y que se puede aprovechar incluso en tabletas, smartphones y hasta en routers Wi-Fi.

Si esta alternativa es muy compleja, también existe la posibilidad de probar Spotflux , un software muy simple (que por ahora es freeware ya que todavía está en desarrollo), disponible para PC y Mac. Prometen futuras versiones para dispositivos móviles.

 

Por supuesto, las prestaciones de las VPN van más allá del consumo de contenidos. Son servicios muy útiles para establecer una navegación Web segura en entornos como cafés u hoteles con conexiones públicas de Wi-Fi.Incluso en servicios globales que ya se encuentran disponibles en la Argentina, tales como la plataforma de descargas iTunes de Apple o el videoclub online Netflix, ofrecen un catálogo diferente (en algunos casos más actualizado, pero sin subtítulos en español en el caso de las películas) si se accede a allos a través de una VPN.

A pesar de sus prestaciones, la VPN no nos puede resolver la posibilidad de tener un servicio pago mensual de Spotify en la modalidad móvil.

¿Se imaginan llevar un servicio de streaming ilimitado de canciones en el celular? Bueno, por más que quisieran pagar los diez dólares mensuales que insume este excelente plan, las limitaciones de contenidos vuelven a estar presentes: sólo se puede abonar con tarjetas de crédito, débito o cuentas de PayPal radicadas en el país en donde Spotify se encuentra habilitado por las discográficas a ofrecer su catálogo musical.

Al final, y a contramano del espíritu libre que tenía Internet en sus comienzos, el dinero sólo vale según de dónde venga, más allá de la buena predisposición que puedan llegar a tener los consumidores..

My Personal Experience with Spotflux internet privacy application

The product website was sent to me from the author who got to know about me through the web, before I downloaded the product, I carefully went through the website and I feel if all the recipes provided on the website were true, this product is worth trying out.

Experiencing no difficulty, I downloaded the software, which was redirected from CNET download.com, I installed and guess what, and the experience has been great so far.

My other internet provider usually has a difficulty in visiting some web at afternoon hours, the power of Spotflux has worked wonders, and the product is just great. Unlike the VPN and Proxy which redirects, Spotflux is something totally different.

What amazes me so much is that this service is free; I guess these guys are running a philantropy organization because I know how much I pay to get a VPN service. I have tried so much of them anyway; none has really pleased me to an extent.

Article from GigaOm.

Zscaler a four-year-old startup that has bootstrapped its business by providing a new form of security designed for a mobile and cloud-dependent workforce, has raised $38 million in first-time financing. The round was led by Lightspeed Venture Partners and an unnamed strategic investor.

Zscaler has been fairly successful in its four years building a significant base of clients including Crutchfield Corporation, La-Z-Boy and Telefonica. The company’s software as a service is hosted in more than 100 data centers around the world and essentially protects a company’s web traffic. It does this by routing requests through Zscaler’s software. But there’s no software for users to download on their clients and there’s also no appliance for corporate IT to worry about.

As the cloud and mobility do away with the perimeter model of security where a firewall may prevent harmful traffic from getting in and corporate secrets from getting out, Zscaler is one of several new companies trying to adapt security to a world where there is no perimeter. And even if the corporate IT thought it had a perimeter, the corporation may not own it or have a say in what runs on it. A perfect example of this might be the CEO’s iPad (a aapl).

Zscaler doesn’t solve all problems, but it’s certainly ahead of the pack in thinking about security in a forward-looking way. Other companies trying to address the changes in security required by BYOD and corporate access to the cloud applications are Bromium and CloudPassage. And by waiting to take on venture capital Zscaler’s CEO Jay Chaudhry has joined a select group of established companies who are finally succumbing to the lure of VC cash. For example Qualtrics, a ten-year-old company this year raised $70 million in its first round of outside investment. Another company, Code 42, avoided VC dollars for 11 years before this year raising $52.5 million.

Article from NYTimes.

The Knight Capital Group confirmed on Monday that it had struck a $400 million rescue deal with a group of investors, staving off collapse after a recent trading mishap, even as the New York Stock Exchange temporarily revoked the firm’s market-making responsibilities.

The rescue package, which was arranged by the Jefferies Group, includes investments from TD Ameritrade and the Blackstone Group. Getco and Stifel, Nicolaus & Company were also involved.

“We are grateful for the support of these leading Wall Street firms that came together to invest in Knight,” Tom Joyce, the firm’s chairman and chief executive, said in a statement. “The array of participants in this capital infusion underscores Knight’s critical role in the capital markets.”

In a regulatory filing, Knight Capital said the investors agreed to purchase $400 million of the brokerage firm’s preferred stock. Under the terms of the deal, Knight will also expand its board by adding three new members.

The deal could provide the investors with more than 260 million shares of the firm, affording the investors the right to buy the shares at $1.50 a piece, according to the statement. Last week, before the trading blunder, the firm’s shares closed over $10.

The rescue deal will hugely dilute existing shareholders of the company. In mid-morning trading, shares of Knight Capital were down 24 percent.

The lifeline was assembled in the wake of Knight Capital’s disclosure of a $440 million trading loss. The loss stemmed from a technology error that occurred on Wednesday when the firm unveiled new trading software, a glitch that generated erroneous orders to buy shares of major stocks. The orders affected the shares of 148 companies, including Ford Motor, RadioShack and American Airlines, sending the markets into upheaval.

Knight Capital said it reached the deal on Sunday, and it expected to close the transaction on Monday. It was a rapid a recovery for a firm that just days ago was facing collapse.

Still, the firm faces significant challenges. The New York Stock Exchange said on Monday it “temporarily” reassigned the firm’s market-making responsibilities for more than 600 securities to Getco, the high-speed trading firm that also invested in Knight. Market makers buy and sell securities on behalf of clients.

The move, the exchange said in a statement on Monday, was a stop-gap measure needed until the investor deal was final. Once the recapitalization plan is complete, Knight will resume its duties.

“We believe this interim transition is in the best interests of investors, our listed issuers, market stability and efficiency, as well as Knight, as the firm finalizes its equity financing transaction,” Larry Leibowitz, chief operating officer of NYSE Euronext, said in the statement.

Knight Capital also faces heavy regulatory scrutiny. The Securities and Exchange Commission is examining potential legal violations as it pieces together the firm’s missteps.

The problems for Knight Capital began at the start of trading on Wednesday. The firm tweaked its computer coding to push itself onto a new trading platform that the New York Stock Exchange opened that day. Under this program, trades from retail investors shift to a special platform where firms like Knight compete to offer them the best price.

But when Knight’s new system went live, the firm “experienced a human error and/or a technology malfunction related to its installation of trading software,” the firm explained in the filing on Monday.

Chaos ensued. The error caused Knight to place unauthorized offers to buy and sell shares of big American companies, driving up the volume of trading and causing a stir among traders and exchanges.

Knight had to sell the stocks that it accidentally bought, prompting a $440 million loss. The loss drained Knight’s capital cushion and caused “liquidity pressures,” the firm said in the filing.

“In view of the impact to the company’s capital base and the resultant loss of customer and counterparty confidence, there is substantial doubt about the company’s ability to continue as a going concern,” the filing said.

Knight and its chief executive, Thomas M. Joyce, began contacting potential suitors for parts of the business, and the firm consulted restructuring lawyers on a potential Chapter 11 filing, according to the people with direct knowledge of the matter.

But events soon turned in the firm’s favor.

The firm secured emergency short-term financing that allowed it to operate on Friday, and it used Goldman Sachs to buy at a discount the shares Knight had erroneously accumulated.

Some of the firm’s biggest customers, including TD Ameritrade and Scottrade, said that they had resumed doing business with Knight by Friday afternoon.

The firm capped its efforts to stay afloat on Sunday with the rescue deal. Knight expects to finalize the agreement on Monday morning and detail the financing terms in a regulatory filing.

“Knight’s financial position and capital base have been restored to a level that more than offsets the loss incurred last week,” Mr. Joyce said in a statement. “We thank our clients, employees and partners for their steadfastness during a brief yet difficult period and we are getting back to business as usual.”
