De forma surpreendente, a discussão sobre o padrão de Rádio Digital Brasileiro, que foi propositalmente esquecida pela grande mídia (sempre enviesada no sentido de garantir benefícios próprios, apoiadores do HD Radio), esquentou muito nas últimas semanas, graças a ativistas pró DRM (Digital Radio Mondiale) que de forma relativamente isolada começaram um grande movimento para a escolha de um padrão decente para o rádio brasileiro.

A situação ganhou um carater de disputa direta quando o CEO da Ibiquity, Robert Struble, lançou uma "Carta aberta aos nossos amigos brasileiros", que foi respondida por Michel Penneroux, também do alto escalão do consórcio DRM, que por sua vez foi respondida por John Schneider, mais um do alto escalão da Ibiquity. A Thomson, empresa integrante do consórcio DRM também tomou partido nesses últimos dias.

Since 1988, the Office of the United States Trade Representative has released an annual Special 301 Report which “examines in detail the adequacy and effectiveness of intellectual property rights” for every country in the world. The intention is to classify countries that either encourage or turn a blind eye to intellectual property piracy and countries can be put on a “Watch List” or “Priority Watch List”. This designation can then be used to pressure countries during trade negotiations.

Andres Guadamuz, a lecturer in law at the University of Edinburgh, recently noticed that the International Intellectual Property Alliance (IIPA) has been lobbying US Trade Representative Ron Kirk to designate countries that have mandated the use of free software (specifically, Brazil, Indonesia and India) to be placed on the Special 301 Watch List. The IIPA is a private sector coalition of trade associations, including the Business Software Alliance, Motion Picture Association of America (MPAA) and the Recording Industry Association of America (RIAA); these names are familiar to digital freedom supporters as cartels hell-bent on using their power to suffocate internet freedoms and to change the course of humanity’s path towards information-based societies in the interest of their enormous profiteering.

The assertion that a country’s choice to use free software is equivalent to illegal piracy is an absurdity and a desperate response to the the free software revolution happening throughout the world. In the 498-page Special 301 report released by the IIPA, they attack Brazil’s policy of mandating the use of free software on page 183 as a reason to keep it on the watchlist:

“Government software procurement: The Brazilian Government should be encouraged to continue its efforts to implement effective software asset management practices in its public ministries and agencies, while avoiding mandates for procurement of software based on the model of development or the business model of the developer.”

On page 170, the IIPA clarifies its demands of the Brazilian government:

“Avoid legislation on the mandatory use of open source software by government agencies and government controlled companies.”

Then, the IIPA takes us to Indonesia. Starting on page 79, they attempt to form a coherent argument about how mandating a switch to open source software is somehow an act against US trade interests:

“[I]n March 2009, the Ministry of Administrative Reform (MenPAN) issued Circular Letter No. 1 of 2009 to all central and provincial government offices including State-owned enterprises, endorsing the use and adoption of open source software within government organizations. While the government issued this circular in part with the stated goal to ‘reduc[e] software copyright violation[s],’ in fact, by denying technology choice, the measure will create additional trade barriers and deny fair and equitable market access to software companies.”

Huh? It’s as if the IIPA forgot that plenty of US companies sell open source software — a fact that they probably “forgot” because no open source software company is paying them off. Why is this form of institutionalized bribery accepted? The IIPA goes on to demand that Indonesia rescind this order on page 80:

“IIPA requests that the government of Indonesia take the following actions, which would result in the most significant near term commercial benefits to the copyright industries: […] Rescind March 2009 MenPAN circular letter endorsing the use and adoption of open source software […]”

The IIPA’s war against the free software revolution then takes us to the Philippines on page 148:

“IIPA was concerned regarding reports of consideration of a Free Open Source Software bill which would require government offices to use open source software. Passage of that bill would deny technology choice regarding software usage and ultimately would stunt the growth of the IT industry in the Philippines.”

Thailand’s commitment to open source is attacked on page 353:

“Among other market access restrictions to be addressed, reverse proposed policy mandating use of open source software, and, e.g., requiring bundling of government funded computers and computers for schools with open source software; maintain neutral policies with respect to technology choice.”

Vietnam is instructed to avoid open source on page 396: “Cease government-endorsed open source preference policy which is limiting technology choice in Vietnam.”

And, Ecuador is also cited for dangerously choosing open source software on page 453: “Most of USTR’s concerns were directed at patent issues, but one major copyright problem highlighted involved a poorly drafted provision in the Education Law which appears to allow free software to educational institutions. Due to their concerns, USTR moved Ecuador back to the Watch List […]”

The IIPA Report makes a few things very clear. First, although this is already well-known, the software industry is scared to death of open source software and must resort to strong-arming as it’s only means of competing with it. Second, free software is spreading like wildfire all over the world as the smart defense against the proprietary software industry. And, finally, we can see why free software for taxpayers is not gaining traction in the United States, where industry lobby groups have a much easier time bribing decision-makers.

The Brazilian federal government has launched a new version of their portal, offering more than 500 online services to Brazilian citizens, built entirely with free software. The new design and layout looks great and, in honor of the release, NXS is providing a translation of the press release about the launch. Translated from Portal Brasil: um novo conceito de comunicação (March 5, 2010) by North-by-South:

“The Brazil Portal marks a new stage in the communication from the State with society and the media,” declared the the president, Luiz Inácio Lula da Silva, during the launch of the new version of the www.brasil.gov.br website, held last Wednesday, the 3rd, by the Secretary of Communication for the Presidency - Secom.

According to Secom, the Portal was envisioned and developed to break with the current models of digital communication from the government. The proposed environment is to offer personalized content to diverse public interests, to gather in one space more than 500 services of electronic government and to promote interactivity between users and the State. “The Portal is a permanent work-in-progress and, therefore, open to everyone’s opinion,” the Secretary of Secom, Franklin Martins, said.

The Secretary emphasized the innovative design of the Brazil Portal and the importance of multimedia content. For him, this is an experience that treats information as a whole in the digital environment.

The form of navigation in the website is matched up with the user’s preference, since the Portal offers the organization of information by profile or themes. Workers, students, entrepreneurs and journalists get targeted content and Secom already plans for the creation of new profiles.

For the international version, the division is by focus of interest: investors, tourists and students. “We are radicalizing the experience of electronic government in Brazil,” said the Minister of Planning, Budgets and Management, Paulo Bernando.

Technology: The Brazil Portal is developed with Plone 3.1.7 and runs on Zope Application Server 2.10.6, programmed in Python 2.4.4. “The use of free platforms is the direction of the federal government. And the choice of the tools for the construction of the Portal would not be different. So, we chose Zope/Plone,” explained Silvia Sardinha, Director of the Internet and Events for Secom.

Cintia Cinquini, from the Presidency’s Department of Technology, said that Plone is a widely-used platform in the government to add distinctive features, such as usability (a multiuser platform with easy management), accessibility (standardized resources) and security.

The new Portal is hosted on servers at Serpro and counts on the support and experience of the company in the use of this software.

Oi Pessoal,
Coloco aqui um pequeno guia para receber Rádio Digital em OM e OC.
Como os receptores DRM ainda são caros e somente estarão disponíveis no mercado por um preço acessível em 2011, apresento aqui uma solução de qualidade superior, custo relativamente acessível e ampla flexibilidade (usando SDR - Software Defined Radio).

Como receptor de rádio, recomendo o K-PO WR2100, um rádio portátil, de dupla conversão, PLL, com uma antena telescópica grande que permite que você receba rádios em Ondas Curtas com uma qualidade muito boa, antena de ferrite, que permite recepção em OM com uma boa qualidade também, além de recepção FM mono ou estéreo selecionável, ganho de RF, e vários outros recursos, sendo que o mais importante para se receber rádio digital, é a saída de FI (Frequencia Intermédiária) em 455kHz.

On January 25th, SourceForge.net published a post on their official blog explaining that they were denying SourceForge services and site access to users residing in countries on the United States Office of Foreign Assets Control (OFAC) sanction list, including Cuba, Iran, North Korea, Sudan, and Syria. Since 2003, the SourceForge.net Terms and Conditions of Use have prohibited people from those countries from accessing their website but they only began enforcing the condition a week before posting the blog entry.

Part of their justification reads: “Our need to follow those laws supersedes any wishes we might have to make our community as inclusive as possible. The possible penalties for violating these restrictions include fines and imprisonment. Other hosting companies based in the US have similar legal and technical restrictions in place.”

Although, many users have posted comments criticizing SourceForge’s decision. Some, such as afsharm, who has contributed to projects hosted on SourceForge and can no longer access his work now: “I am an Iranian (an innocent one) and I am not responsible for what ever my government is doing. As nawwark mentioned I’ve sometimes have contributions in SF.NET projects, so why you are denying me from my own works? It’s against freedom and against FOSS.”

Others, like yemeth, could not understand how a project based in another country can be considered a US product: “I seriously can’t understand this. I’m Spanish, and my technology isn’t northamerican. It has nothing to do with the United States except that is hosted here. I can’t understand why said government has anything to say about my will to share my code with EVERYONE. I have no personal embargo against Cuba, nor does my country.”

And there were those, like pmarkiewicz, who pointed out the easier solution: “Folks, if you visit http://www.torproject.org and install tor, then SourceForge can not determine your country of origin. If you happen to traverse through an exit node that is not in an ‘axis of evil’ country, then there is no reason you would be denied that code. Senator Clinton even endorsed efforts to provide these tools to dissenters.”

The comment makes reference to Secretary of State Clinton’s request to Twitter to postpone a planned maintenance shutdown during the election protests in Iran, so that Iranian users could access and use the website (seemingly putting Twitter at legal risk, following the logic used by SourceForge). At the time, she said: “And it is the case that one of the means of expression, the use of Twitter is a very important one, not only to the Iranian people but now increasingly to people around the world, and most particularly to young people.”

Two weeks later, SourceForge posted another entry on their blog, announcing a change in their decision. Now, they have removed the block and added a feature that allows project owners to ban access to the sanctioned countries:

Beginning now, every project admin can click on Develop -> Project Admin -> Project Settings to find a new section called Export Control. By default, we’ve ticked the more restrictive setting. If you conclude that your project is *not* subject to export regulations, or any other related prohibitions, you may now tick the other check mark and click Update. After that, all users will be able to download your project files as they did before last month’s change.

While this was a positive change in the eyes of some, there are still many unanswered questions from SF users, especially those from outside of the US. They don’t understand the US laws and are not sure if they will be in some kind of trouble by choosing to freely distribute their software.

To be fair, SourceForge.net is not the only web service to block users from the sanctioned countries. NXS News reported on this before when it was noticed that Google was blocking access to users based on the country they were surfing from. The consensus being floated around the FOSS community is to start choosing hosts outside the US for their projects, where restrictions on internet use are not so strict. A good option would be Launchpad.net in the UK, used by MySQL and Ubuntu. Either way, the US Government’s arguments about standing up for freedom (remember, “they hate us for our freedom”) is certainly diluted by their own efforts to restrict the individual freedom of people to freely use the internet, regardless of where in the world they happen to be when using it.

CARTOGRAFA COMO ACTIVISMO GLOBAL

Los mapas son herramientas no neutrales e imprescindibles para
transformar la realidad. Históricamente han servido, por ejemplo, para
planificar la conquista militar o para promover la explotación
turística de ciudades y territorios. O como en el caso de la invasion
de Iraq, para manipular la mente de la poblacion con un mapa falseado

Com o Rádio Digital, o já antigo uso (mais de 80 anos) da faixa de OC (Ondas Curtas) pode ganhar nova vida. Para os que ouvem Ondas Curtas, estamos acostumados aos efeitos do desvanecimento e dos constantes xiados que acontecem na recepção AM na faixa de Ondas Curtas. Ao mesmo tempo que estamos acostumados a ouvir rádios em linguas que jamais imaginamos em escutar, rádios do leste europeu, rádios em árabe, a Rádio Habana Cuba, Rádio Nacional da Amazônia, BBC World Service, Rádios daqui do lado em espanhol e assim por diante.

Ao mesmo tempo que propicia que transmissões sejam ouvidas em locais muitos distantes, o som que chega ao ouvido do ouvinte muitas vezes tem uma qualidade sofrível, e este fato levou hoje a faixa de Ondas Curtas quase ao esquecimento, com uma diminuição do número de rádios e ouvintes dessa fantástica banda de transmissão.

Pessoal,

Estou lendo a tese de doutorado do Flávio Ferreira Lima, hoje no Ministério das Comunicações, e um dos principais responsáveis pelo estudo da digitalização no rádio no Brasil.

A tese é muito foda, e muito esclarecedora sobre como funcionam as intrigantes transmissões em Ondas Médias, Ondas Tropicais e Ondas Curtas, e é claro, sobre trasmissão digital de rádio nessas faixas de frequência.
