A CryptoRave é um evento anual que reúne, em 24 horas (+ festa a ser divulgada), diversas atividades sobre segurança, criptografia, hacking, anonimato, privacidade e liberdade na rede

A CryptoRave é aberta e gratuita e realizada na cidade de São Paulo, as inscrições serão feitas no local.

Inspirada em uma ação global, descentralizada para disseminar e democratizar o conhecimento e conceitos básicos de criptografia e software livre, o evento teve início em 2014, como reação à divulgação de informações que confirmaram a ação de governos e corporações para manter a população mundial sob vigilância e monitoramento constante. Junte-se a nós!

A programação parece muito boa!

 

This is the first of a two volume Special Issue. Both volumes will have a focus on commoning and property. The essay in this first volume - divided into three main parts, which can be read separately - is based on an inter-disciplinary PhD thesis titled “Property, Commoning and the Politics of Free Software” completed February 2010, by J. Martin Pedersen. Volume 2 will further combine practical insights with theoretical perspectives.

In legal and philosophical terms, property relations are relations between people with regard to things. In this way, the organisation of a commons is encoded in its property rules, which structure its use, access and decision-making rights and responsibilities accordingly. Property, then, is central to debates about commons and commoning: how do commoners relate to each other with regard to a given resource (land, code, rivers, forests, hills, cars) and how is a commons defined vis-a-vis the rest of the world? Questions such as class, gender and other hierarchies, environmental justice, sustainability and spirituality are relevant here. Most of these social dynamics – most of the time, even on the “outside of capital”– turn on property relations: who has access to what (tools, resources, land), when and under what conditions, who gets to decide and how are decisions made?

Often, however, property is juxtaposed to commons – as if commoning was a negation of property. Unfortunately, this view presupposes and consolidates a very narrow understanding of property, where the general is conflated with the particular. Property relations are not only exclusive, private property rights as instantiated within capitalist democracy (that is, a particular conception of property). As a jurisprudential concept, property can be used to understand, analyse, reflect upon and organise social relations with regard to things in any context (this is the general conception of property). The conflation of the general with the particular, which conceals the historical and anthropological fact that property can be and is understood (very) differently, takes on a further dimension in colloquial talk. We have come to accept that property is stuff: things that we own, and that we own exclusively. As a rhetorical device in privatisation arguments it is very powerful because it invokes feelings that are close to home, literally. We say things like “this house is my property”.

Similarly, privatisation arguments in the context of immaterial goods and resources invoke the same passions and feelings: this text or this source code “is the property of Microsoft”. Such a conception of property is not only a conflation, but furthermore hides the complexity of the social relations that property arrangements circumscribe and give rise to.

It is obvious that social, cultural and political practices define any given property regime, hence analytically exploring property relations gives us an insight into the relation between the socio-cultural and the law. It is precisely at this level that commons are created and organised - and through the language of property we can articulate practices of commoning into property protocols (rules and agreements) that can provide stability of the commons on the inside and protection against threats of capital’s enclosure from the outside. Self-determination and autonomy begins by taking the law into your own hands.

The purpose of this Special Issue is to instigate further debate about property, commoning and commons. In this first volume, the Free Software movement, which has autonomously constituted itself by articulating their social values in the GNU General Public License, is presented as an example of a commons, a commoning community, and critically analysed through the lens of property.

Doing so reveals that philosophical and political principles underlying the Free Software and the wider Free Culture movements fail to address the threat of enclosure at the most fundamental level, namely in the material realm. Without confronting ownership of land, its resources, and the means of production, the Free Software and Free Culture movements remain liable to the threat of enclosure.

After all, all immaterial things have a material base (space, energy, labour, resources, distribution) and exclusive control over these material underpinnings is de facto control over the immaterial goods that may spring from their potential.

 

Open-source, Decentralized Online Social Networks (DOSNs) are emerging as alternatives to the popular yet centralized and profit-driven platforms like Facebook or Twitter. In DOSNs, users can set up their own server, or instance, while they can actually interact with users of other instances. Moreover, by adopting the same communication protocol, DOSNs become part of a massive social network, namely the Fediverse. Mastodon is the most relevant platform in the Fediverse to date, and also the one that has attracted attention from the research community. Existing studies are however limited to an analysis of a relatively outdated sample of Mastodon focusing on few aspects at a user level, while several open questions have not been answered yet, especially at the instance level. In this work, we aim at pushing forward our understanding of the Fediverse by leveraging the primary role of Mastodon therein. Our first contribution is the building of an up-to-date and highly representative dataset of Mastodon. Upon this new data, we have defined a network model over Mastodon instances and exploited it to investigate three major aspects: the structural features of the Mastodon network of instances from a macroscopic as well as a mesoscopic perspective, to unveil the distinguishing traits of the underlying federative mechanism; the backbone of the network, to discover the essential interrelations between the instances; and the growth of Mastodon, to understand how the shape of the instance network has evolved during the last few years, also when broading the scope to account for instances belonging to other platforms. Our extensive analysis of the above aspects has provided a number of findings that reveal distinguishing features of Mastodon and that can be used as a starting point for the discovery of all the DOSN Fediverse.

 

Sei que no Reddit tem o r/UFMG com muitos estudantes de computação. Somos poucos aqui, mas parece uma iniciativa legal. Me disponibilizo pra moderar também, e divulgar na própria faculdade :)

Opa gente boa noite, beleza?

Tô fazendo meu trabalho de conclusão de curso em cima do fediverse, e meus orientadores recomendaram crawlear as redes pra fazer algumas análises. Como entendo que tá todo mundo meio ferrado com esses scrappers pra GPTs da vida, queria saber se isso seria okay pelos admins e qual seria a forma mais "respeitosa" de coletar esses dados sem gerar custos pro hosting.

 

Tô considerando subir uma instância de alguma coisa numa organização que participo, e quero primeiro checar minhas opções. Obviamente eu prefiriria o lemmy, mas ouvi falar de um Mastodon-like que chama Akkoma que parece mais leve. Quais vocês gostam de usar além daqui?

 

À medida que governos progressistas tomam posse no Sul Global, agora mais do que nunca há uma necessidade premente de uma nova teoria de desenvolvimento que possa satisfazer as aspirações prometeicas das nações do terceiro mundo.

Leitura obrigatória.
