Are Hackers the Next Bogeyman Used to Scare Americans Into Giving Up More Rights? | Alternet -
"That's just a tiny bit overwrought for an allegedly serious expert, don't you think? In fact, it sounds like the kind of thing we heard from various members of the Bush administration during the early days after 9/11. And it certainly indicates, as Wheeler has been speculating, that the government is stretching the terrorism laws to include hacking. They certainly are using the same histrionic language to describe it." - Miguel Caetano from Bookmarklet
Google confirms critical Android crypto flaw used in $5,700 Bitcoin heist - Dan Goodin (Ars Technica) -
Google confirms critical Android crypto flaw used in $5,700 Bitcoin heist - Dan Goodin (Ars Technica)
"Google developers have confirmed a cryptographic vulnerability in the Android operating system that researchers say could generate serious security glitches on hundreds of thousands of end user apps, many of them used to make Bitcoin transactions. This weakness in Android's Java Cryptography Architecture is the root cause of a Bitcoin transaction that reportedly was exploited to pilfer about $5,720 worth of bitcoins out of a digital wallet last week. The disclosure, included in a blog post published Wednesday by Google security engineer Alex Klyubin, was the first official confirmation of the Android vulnerability since Ars and others reported the incident last weekend. Klyubin warned that other apps might also be compromised unless developers change the way they access so-called PRNGs, short for pseudo random number generators." - Miguel Caetano from Bookmarklet

The Open Internet Advisory Committee at one year - Shane Greenstein (Digitopoly) -
"Let’s be clear about what we accomplished. We did not make policy for data caps. Rather, the report mapped the policy landscape. It identified and analyzed where the FCC or another consumer-protection policy-making body, such as FTC, might want to monitor events and where issues remained unsettled. It identified some choices too, and tried to identify bridges between general arguments and specific observable behavior and facts. Unless I am mistaken, we were the first organization to ever do something this comprehensive on this topic – namely, map the landscape by bringing all the arguments into one place. We did not settle anything, nor was it within our purview to settle anything. Rather, we attempted to move the conversation to a more productive place. Call me a naïve idealist, but that is what productive policy discussions are supposed to do." - Miguel Caetano from Bookmarklet

#Capitalism: Poder dos EUA foi construído com crises e Estado, dizem acadêmicos canadianos Leo Panitch e Sam Gindin - Eleanora de Lucena (Folha de S. Paulo) -
"Os autores começam desconstruindo a "falsa dicotomia entre Estados e mercados". Narram como o Estado atuou para estabelecer regras para a propriedade e competição que facilitaram a expansão das empresas dos EUA e a acumulação de capital. Tarifas de proteção à produção nacional, programas de infraestrutura, financiamento à inovação: tudo foi usado para a montagem do poder americano no início do século 20. Na área externa, deu apoio a ditadores locais e a proprietários de terras, o que ajudou a bloquear desenvolvimento." - Miguel Caetano from Bookmarklet

Open Content, An Idea Whose Time Has Come - James Cuno (J. Paul Getty Trust/The Getty Iris) #OpenCulture #OpenContent
"Today the Getty becomes an even more engaged digital citizen, one that shares its collections, research, and knowledge more openly than ever before. We’ve launched the Open Content Program to share, freely and without restriction, as many of the Getty’s digital resources as possible. The initial focus of the Open Content Program is to make available all images of public domain artworks in the Getty’s collections. Today we’ve taken a first step toward this goal by making roughly 4,600 high-resolution images of the Museum’s collection free to use, modify, and publish for any purpose." - Miguel Caetano from Bookmarklet

"The U.S security industry fears that it stands to lose $22-$35 billion over the next 3 years. This  as result of the PRISM effect abroad, especially in the European market.

However many voices in the EU are questioning the transparency of these services, thanks to the Guardian revelations concerning PRISM." - Miguel Caetano from Bookmarklet

"Ao finalizar a sua apresentação, Gerd Leonhard expõe que estamos caminhando para a era do desafio da privacidade global. Isto é, é preciso descobrir uma fórmula que utilize os dados das pessoas sem expô-las a todo o resto que está acontecendo. Afirma ainda que esse é o desafio crucial para os negócios na área de publicidade e marketing. E vocês o que acham? Acreditam que é possível explorar os dados das pessoas sem invadir a sua privacidade? Para mim é um contrassenso." - Miguel Caetano from Bookmarklet

Commodify Us: Our Data Our Terms - Marc Garrett (
"A significant value offered by the Commodify.Us platform is the power to manage our own data. The simple act of downloading our own data from Facebook, and then uploading it to Commodify.Us supports us to rethink what all this information is. What once was just abstract data suddenly becomes material that we can manipulate. Alongside this realization arrives the understanding that this material was made by our interactions with all these platforms, and that other people are spying on us and making money out of it all. Once this data material is uploaded onto the Commodify.Us platform, it ask if we want this stuff to be a product under our own terms, or if we wish to make art out of it using their tools." - Miguel Caetano from Bookmarklet
Varieties of what? Should we still be Using the Concept of Capitalism? - Fred Block (Political Power and Social Theory) -
"This article argues that social scientists should reconsider the analytic value of the term “capitalism.” The paper argues that the two most coherent definitions of capitalism are those derived from classical Marxism and from the World System theory of Immanuel Wallerstein. Marx and Engels’ formulation was basically a genetic theory in which the structure of a mode of production is determined by the mode of surplus extraction. During the course of the 20th century, however, Marxist theorists had to modify this framework and the result has been an uncomfortable hybrid. Wallerstein resolved these tensions by redefining capitalism in terms of the logic of a world system. However, his argument has difficulty in explaining the consequential variations over time in the specific rules and institutional structures that operate at the global level. The article goes on to argue in favor of Karl Polanyi's concept of market society because it focuses attention on the political governance of market societies at both the national and the global levels." - Miguel Caetano from Bookmarklet

Obama's NSA Reforms Off to a Bad Start - Timothy Karr (MediaCitizen)
"Obama said he wants "greater oversight, greater transparency, and constraints" on vacuuming up data, and urged Americans to trust him that abuses to existing laws weren't occurring. But the president seems unable to grasp that Americans want more than accountability for the wholesale surveillance of our online lives. We want the government to stop it altogether. And it may take the independent investigatory committee that the StopWatchingUs coalition has called for, and a significant rewrite of several surveillance laws already on the books." - Miguel Caetano from Bookmarklet

The Daily Mail caught plagiarising an entire article. Surprised? - Zee (The Next Web)
"Daily Mail author Ruth Styles published an article on the world’s worst tourists one day after author XJ Selman published his. Both articles had a similar focus and both feature exactly the same examples. It’s a shame really, I remember spotting that article yesterday on The Daily Mail and thinking “Genius idea for an article. Maybe the Daily Mail deserves its record traffic after all.” Sadly not, and what’s more, this appears to be a regular occurrence - this other example is from three days ago." - Miguel Caetano from Bookmarklet

Google Tells Court You Cannot Expect Privacy When Sending Messages to Gmail -- People Who Care About Privacy Should Not Use Service, Consumer Watchdog Says | Consumer Watchdog
"In a stunning admission contained in a brief filed recently in federal court, lawyers for Google said people should not expect privacy when they send messages to a Gmail account. Consumer Watchdog said today that people who care about their email correspondents’ privacy should not use the Internet giant’s service. Google’s brief said: “Just as a sender of a letter to a business colleague cannot be surprised that the recipient’s assistant opens the letter, people who use web-based email today cannot be surprised if their emails are processed by the recipient’s [email provider] in the course of delivery. Indeed, ‘a person has no legitimate expectation of privacy in information he voluntarily turns over to third parties.’”  (Motion to dismiss, Page 19)" - Miguel Caetano from Bookmarklet
Riseup and Government FAQ: Riseup and the recent email provider closures ( -
"We have received your emails asking a number of good questions in light of last week’s news about Lavabit and SilentCircle closing down (1). We would like to clearly state that Riseup has never given any user information to any third party. We have never permitted installation of any hardware or software monitoring on any system that we control. We will do everything in our power to protect the data of social movements and activists, short of extended incarceration. We would rather pull the plug than submit to repressive surveillance by our government, or any government. We are doing everything we can, as quickly as possible, to forge forward with options that would prevent us from having to shut down, in case we are faced with making such a decision. In cooperation with other groups, we are hard at work to develop and deploy a radical new infrastructure that would allow us to provide email in a way that is a thousand times more secure and that would prevent us from having access to any user’s data. We have been working on this for over a year, but we have a lot more work to do before it is finalized." - Miguel Caetano from Bookmarklet
Concorrência: No Brasil, menos é mais - Mariana Mazza ( -
"O caso norte-americano derruba a tese sustentada até agora que a união de grandes companhias é uma "tendência internacional", como gostam de dizer os burocratas de plantão. Essas incorporações também não tem o condão de melhorar a economia de ninguém. Fosse este o caso e os Estados Unidos seriam os primeiros a brindar com a American Airlines e a US Airways. O movimento feito pelo Departamento de Justiça norte-americano pode até não dar em nada, mas mostra o fim dessa "tendência" que tantos falam. Com a economia ainda frágil, os norte-americanos agora estão mais preocupados com a própria casa do que em conquistar novas fronteiras com empresas multinacionais. E o primeiro passo para assegurar a saúde financeira de seus cidadãos é preservar a concorrência e assegurar que a livre iniciativa realmente tenha espaço para florescer." - Miguel Caetano from Bookmarklet
DON'T FEED THE TROLLS!: Managing troublemakers in magazines' online communities - Amy Binns (Journalism Practice, Volume 6, Issue 4) -
"“Trolling” and other negative behaviour on magazine websites is widespread, ranging from subtly provocative behaviour to outright abuse. Publishers have sought to develop lively online communities, with high levels of user-generated content. Methods of building sites have developed quickly, but methods of managing them have lagged behind. Some publishers have then felt overwhelmed by the size and behaviour of the communities they have created. This paper considers the reasons behind trolling and the tools digital editors have developed to manage their communities, taking up the role of Zygmunt Bauman's gardeners in what they sometimes refer to as “walled gardens” within the Internet's wild domains. Interviews were conducted with online editors at the front line of site management at Bauer, Giraffe, IPC, Natmags, RBI and the Times. This article shows how publishers are designing sites that encourage constructive posting, and taking a more active part in site management. Web 2.0 and... more... - Miguel Caetano from Bookmarklet
Newspaper comments: Forget anonymity! The problem is management — Scott Rosenberg's Wordyard -
"Why didn’t newspapers do this to begin with? I think part of the problem is that a lot of them had only the vaguest rationale for opening up comments in the first place. Maybe some consultant told them it was a good idea. Or it looked like the right thing to do to the young members of the Web team, and the front office said “Go ahead and play, kids, just don’t spend any money.” And the comments got turned on with no one minding the store and no clear goal in mind, either on the business side or in the newsroom. So, media website operators, I suggest that you ask yourselves: When you opened up comments, was it really about having a conversation with the readers? Then have that conversation! Get the editors and reporters in there mixing it up with the public. Sure, there will be problems and awkward moments; there will also be breakthroughs in understanding. Maybe, though, no one was ever really serious about that conversation. Maybe the idea was to boost ad impressions with an... more... - Miguel Caetano from Bookmarklet
Why Anonymity Exists and Works on Newspapers' Web Sites - Steve Yelvington (Nieman Reports) -
"Those voices are now being heard on the Internet, where anyone can become a blogger in the two minutes it takes to fill out a form and create an account on any of the many free blog-hosting and social-networking sites. There is no longer a scarcity of places in which public conversation and interaction can happen. Some journalists, such as blogger Jeff Jarvis, have begun to question whether the editorial page has outlived its usefulness. Community conversation will thrive even if every newspaper disappears. Is there a vital and continuing role for newspapers, or even for journalists, to play in providing such a forum for civic and social conversation? Community conversation can benefit from a framework of goals, ground rules and leadership, and newspapers can perform a real public service by helping provide this. In online forums, five basic identity models exist, and below they are ranked from the "order" to "liberty" ends of the spectrum:" - Miguel Caetano from Bookmarklet
Navigating between Chaos and Bureaucracy: Backgrounding Trust in Open-Content Communities - Paul B. de Laat (Springer) -
"Many virtual communities that rely on user-generated content (such as social news sites, citizen journals, and encyclopedias in particular) offer unrestricted and immediate ‘write access’ to every contributor. It is argued that these communities do not just assume that the trust granted by that policy is well-placed; they have developed extensive mechanisms that underpin the trust involved (‘backgrounding’). These target contributors (stipulating legal terms of use and developing etiquette, both underscored by sanctions) as well as the contents contributed by them (patrolling for illegal and/or vandalist content, variously performed by humans and bots; voting schemes). Backgrounding trust is argued to be important since it facilitates the avoidance of bureaucratic measures that may easily cause unrest among community members and chase them away." - Miguel Caetano from Bookmarklet
