description: Online conversations today exist primarily in the realm of social media and blogging platforms; these spaces that we so often think of as the “public sphere” are, however, privately owned. Instead of a decentralized Internet, we now have centralized platforms serving as public spaces: a quasi-public sphere that is subject to both public and private content controls spanning multiple jurisdictions and widely different social mores. Private companies set their own standards for content regulations, which often means striking a balance between keeping users happy and operating within a viable business model. A fine line also exists in keeping one’s site uncensored by national governments, while still attempting to provide a space for free expression. As private companies increasingly take on roles in the public sphere, the regulations companies must provide, and the rules users must follow, become increasingly perplex. This discussion will focus on case studies from platforms such as Twitter, Facebook, Blogspot, Flickr, and YouTube, and will look at the issues of content regulation, community policing, anonymity, and account deactivations.

description: Whistleblowing ermöglicht Journalisten und Bloggern neue Chancen für ihre investigative publizistische Arbeit, stellt sie aber auch vor neue Herausforderungen. Es werden Informationen verfügbar sein, die es in dieser Vielfalt und Transparenz zuvor nicht gab, zugleich müssen Publizisten diese Informationen prüfen, aufarbeiten und bewerten – ihre klassische Gatekeeper-Funktion wahren –, in Zeiten des Leaking aber ohne Kenntnis über die Identität der Informanten. Doch nicht nur innerhalb der Medien stehen wir vor großen Veränderungen, auch die Öffentlichkeit, für die wir schreiben, wird eine andere werden. Sie wird nach gezielter Intervention und Aufklärung stärker verlangen als nach vorgefasster Meinung und Bewertung. Und auch andere Institutionen (Stichwort: Open Government, Open Data) müssen dem Anspruch auf Transparenz zunehmend gerecht werden.

Serious Games – Seriously??

uk: Комп'ютерні науки

description: Der Oberbegriff "Serious Games" beschreibt diejenigen Games, deren Ziele über die Unterhaltung hinaus gehen. Vom Bildungsbereich über Weiterbildungs- und Schulungsprogramme deckt das Genre der "ernsten Spiele" bis hin zur politischen Simulation mannigfaltige Themen ab. In der Runde, die sich zur re:play zusammen findet, wollen wir den aktuellen Markt betrachten, über Herausforderungen in der Umsetzung und Rezeption von Serious Games reden, einen Zukunftsausblick wagen und dabei natürlich von der Erfahrung unserer Gäste profitieren. Mit dabei sind Steffen Boos von Daedalic Entertainment, die einige erfolgreiche Serious Games publiziert haben; Christoph K. Weidner, dessen MultiMediaManufaktur das erste PC-Therapiespiel entwickelt hat, welches man in einer Apotheke kaufen kann; und Computerspielforscher Sebastian Deterding.

description: Datenvisualisierungen verwenden grafische Metaphern, um abstrakte Datensätze darzustellen. Sie repräsentieren Daten in einer Weise, dass inhärente Muster und Strukturen sichtbar und verständlich werden. Durch den Siegeszug digitaler Technologien stehen immer komplexere Daten und immer größere Datenmengen zur Verfügung. Es ist die Aufgabe von Designern, gemeinsam mit Experten angemessene und expressive Darstellungsformen zu finden. Um ein breites Publikum erreichen zu können, müssen ästhetisch ansprechende Darstellungen und die Möglichkeit einfacher, interaktiver Erkundung genutzt werden. In unserem Vortrag stellen wir dar, wie Visualisierungen demokratisiert und sich zu einem nützlichen und nutzbaren Medium entwickeln. Unsere These ist, dass die kritische Nutzung von Datenvisualisierungen eine der zentralen Medienkompetenzen des 21. Jahrhunderts werden wird.

Das Internet und insbesondere das Web 2.0. verändern Gesellschaft, Politik und Unternehmen. Marken werden nicht mehr von “oben nach unten”, sondern von den Verbrauchern definiert. Alte Märkte verschwinden oder werden radikal verändert, neue (Online-) Märkte entstehen. Für die Demokratisierung etablierter Machtgefüge spielt das Internet eine immer wichtigere Rolle. Christian Friege, Chef des größten deutschen Öko-Energieanbieters LichtBlick, geht der Frage nach, welche Rolle das Internet jetzt bei der „Demokratisierung“ der Energiemärkte und der ökologischen Energiewende einnimmt und beschreibt unter anderem das SchwarmStrom-Projekt von LichtBlick. Beschleunigt das Web (2.0) den Weg in die CO2- und Atomstrom-freie Wirtschaft? Und wenn ja, wie?

description: In his new book, “The Internet of Elsewhere,” Cyrus Farivar looks at the role of the Internet as a catalyst in transforming communications, politics, and economics. In it, Farivar explores the Internet’s history and effects in four distinct and, to some, surprising societies — Iran, Estonia, South Korea, and Senegal. He profiles Web pioneers in these countries and, at the same time, surveys the environments in which they each work. After all, contends Farivar, despite California’s great success in creating the Internet and spawning companies like Apple and Google, in some areas the United States is still years behind other nations. Don’t forget: – Skype was invented in Estonia–the same country that developed a digital ID system and e-voting; - Iran was the first country in the world to arrest a blogger, in 2003; - South Korea is the most wired country on the planet, with faster and less expensive broadband than anywhere in the United States; - Senegal may be one of sub-Saharan Africa’s best chances for greater Internet access, and yet, continues to lag behind.

description: Das Internet und die Menschen, die es nutzen scheinen ständig in höchster Lebensgefahr zu sein, zumindest wenn man der Empörung, den Shitstorms und den Ängsten glaubt, die durch Blogs, Foren und Communities gehen, sobald mal irgendwo ein Problem auftaucht. Wir wollen uns all diese schrecklichen Themen, die da so durch die Netzwelt geistern (und geisterten) noch mal anschauen und drauf abklopfen, was denn wirklich dran ist: Ist denn wirklich so oft Weltuntergang? Ob es Blogger an den Kragen geht (z.B. aktuell Nerdcore), die Vorratsdatenspeicherung uns in Orwell Staatsbürger verwandelt, die Musikindustrie Gesetze diktiert die uns das Internet wegnehmen kann, ob die Aufhebung der Netzneutralität das Internet in ein Corporate-Web verwandelt, was Streetview eigentlich schlimmes tut bzw. die Verweigerung davon, ob der “Kontrollverlust” wirlich so groß ist oder die angeblich so sorglose Jugend gehirngewaschen und internetsüchtig in ihren Zimmern versauert, ob die allgegenwärtige Schleichwerbung und andere schrecklich bösen Manipulationsversuche (Bahn, Atomlobby,..) so super funktionieren… all das wollen wir einem Reality Check unterziehen. Die These wäre: Die Menschen sind gar nicht so manipulierbar. Sie geben Freiheiten nicht leichtfertig auf. Wenn man jedoch ständig Weltuntergang schreit und am Ende gar nichts schlimmes passiert (sondern im Gegenteil recht schnell sogar jede Menge gute Aktionen und Reaktionen erfolgen) hört man irgendwann nicht mehr drauf, wenn wirklich mal höchster Alarm angesagt ist.

Der Bundesbeauftragte für Informationsfreiheit Peter Schaar hat selbst in seinem zweiten Bericht zur Informationsfreiheit eine kritische Bilanz gezogen und die Praxis der Behörden kritisiert. Doch es ist nicht nur die Praxis der Behörden, die reichlich von den vielen Ausnahmeregelungen gebrauch machen, die ihnen das IFG ermöglicht. Es ist eine mangelhafte Gesetzgebung in Kombination mit einer immer noch weit verbreiteten Geiseshaltung. Vom kulturellen Wandel in den Köpfen und den Amtsstuben sind wir noch immer weit entfernt. Auf diesem Panel wollen wir die Faktoren die dazu beigetragen haben, dass fünf Jahre IFG nicht zur erhofften Transparenz und Offenheit in Politik und Verwaltung geführt haben.

description: Das Internet ist mit Games groß geworden, Computerspiele sind eines der wichtigsten und intensivsten Anwendungen des Netzes. Gaming ist für junge Menschen ein sehr bedeutendes Freizeitvergnügen, es entwickelt sich zu einem der beliebtesten Medien des 21. Jahrhunderts. Vor allem Online-Games wachsen rasant. Da auch im Games-Bereich das Internet die zukünftige Entwicklung vorgibt, steht das vernetzte Spielen einer weltweiten Jugendkultur im Mittelpunkt des Vortrages, etwa in den Sozialen Netzwerken oder den zahlreichen Communitys rund um das Thema Games. Abgerundet wird der Vortrag über Einblicke in die Welt des eSport als spezifische international ausgerichtete digitale Jugendkultur. Der Referent stellt die eSport-Plattform Electronic Sports League (ESL) vor, mit mehr als 2,8 Millionen Mitgliedern die größte eSport-Plattform Europas. In der ESL haben die Mitglieder vielseitige Möglichkeiten der Kommunikation, Information und Selbstdarstellung: Profile, Gästebücher, Foren, News, Live Streams und Videos On Demand können genauso abgerufen wie Fotogalerien und eigene Videos hochgeladen und anderen Nutzern zur Verfügung gestellt werden. Die ESL verbindet Menschen, die die selbe Leidenschaft verfolgen: das Spielen von Computerspielen, vor allem organisiert in Teams (Clans). Die zahlreichen Spielerteams sind ein wichtiger Pfeiler für Gaming-Communitys, vor allem im eSport. Clans sind analog zu herkömmlichen Sportvereinen zu sehen und bieten eine vergleichbare Organisationsstruktur. Ein großes User-Engagement und viele ehrenamtliche Positionen werden von den Computerspielern innerhalb der Social Gaming Networks abgebildet.

description: Während für viele Computerspieler das Prädikat „macht süchtig!“ als Qualitätsmerkmal eines Spiels gilt, wird in der Öffentlichkeit das Phänomen der Computerspielabhängigkeit seit einigen Jahren kontrovers diskutiert. Der Vortrag zeigt, wie „problematisches Computerspielen“ als individuelle Praxis reflektiert und als Phänomen von gesellschaftlicher Relevanz konstruiert wird. Dazu werden Befunde der wissenschaftlichen Forschung, Aussagen von Computerspielern über ihr eigenes Handeln sowie die Perspektive der professionellen Berater bzw. Therapeuten in einschlägigen Beratungseinrichtungen berücksichtigt. Grundlage des Vortrags ist ein Forschungprojekt, das u.a. fallstudienartige Spielanalysen, eine bevölkerungsrepräsentative Befragung sowie leitfadengestützte Interviews mit 40 Computerspielern und mit fünf Experten aus Beratungsstellen für Computerspielabhängigkeit umfasste und im Auftrag der Landesanstalt für Medien NRW durchgeführt wurde.

Wichtigste Instrumente für die (kostenlose) Markenetablierung: Social Media. Mit einem Fingerzeig auf die positive Wechselwirkung zwischen digitaler und realer Welt öffnen Twitter, Foursquare & Co die Schranken zu einem beispiellosen Kreativprozess, der demokratischer wirkt als gleichnamige Regierungsform.

description: Kommunikation (im Sinne von PR) über Medienunterhaltung – insbesondere über moderne Angebote wie Computer- und Videospiele – stellt einige besondere gesellschaftlich verankerte Herausforderungen. Vor allem, weil die Bandbreite möglicher Zugangsweisen hier besonders groß ist: Sie reicht von dem Wunsch nach gesetzlichen Verboten und gesellschaftlicher Ächtung über kritisch-rationale Positionen bis hin zu enthusiastischen Affirmationen. Immer noch sind die Kontroversen hier schärfer als bei den meisten anderen Medienangeboten. Um die Diskussion über Computer- und Videospiele in der Öffentlichkeit zu versachlichen, die Welt der interaktiven Unterhaltung aus ihren vielfältigen Perspektiven zu betrachten und so zur Aufklärung über Wirkung und Rolle dieser Medien in unserer Gesellschaft beizutragen, hat Electronic Arts im Herbst 2010 den EA Blog für digitale Spielkultur ins Leben gerufen. Im Vordergrund steht dabei ausdrücklich die kritische, journalistische Auseinandersetzung mit den dargestellten Themen. Diesen Blog und meine Motivation dahinter möchte ich in meinem Vortrag vorstellen.

description: For a long while, Africa seemed almost cut off from modern means of communication. However, recent events in Tunisia, Egypt and Libya show what status digital communication has now achieved there. The African-Arab wave of protest is largely based on the use of social tools; these platforms are experiencing a veritable explosion (growth of Facebook in Africa in the past six months: 50.12 per cent). But would this be possible in other parts of Africa as well? It is true that broadband Internet access is available only to an elite in most African countries. But Internet cafés and above all mobile Internet are alternatives available to the normal citizen. The growth rate in the number of African mobile communication users is almost 50 per cent – the biggest rate of growth in the world. Telephony, SMS, games and FM reception are important applications. The active posting of information and the formation of interest groups by means of digital networks open up access to educational opportunities and new market chances. Is the wave of protest in North Africa also a form of “cyber-revolution” and would it be possible in other regions of the continent as well? What chances for development do digital media offer people in Africa? How can African countries avoid the danger of a “digital divide” within the continent? Can anything be learnt from Africa’s digital development that can be applied to other world regions with an underdeveloped infrastructure?

description: In the recent political crises in Tunisia, Egypt, and elsewhere in the Middle East – and before that in Iran and Burma – citizen video played a central role in mobilizing people within the country, informing the world about the situation, and feeding mainstream media’s need for on-the-ground stories. There is a blurring of boundaries between the professional human rights defender, the citizen activist, and the journalist; all are documenting human rights violations – and they are also aggregating, shaping, re-mixing and sharing the content of the others. A world of ubiquitous video raises new opportunities to reveal compelling evidence and stories, challenge government propaganda, and galvanize local and international publics. It also raises challenges: how to protect visual anonymity, privacy and the safety of witnesses, survivors and human rights defenders, how to determine the context and authenticity of videos, and how to effectively turn visual evidence into real change. Building on the experience of WITNESS supporting people to use video to create change in policies and practices in over eighty countries this talk will highlight key principles of effective video for advocacy, emerging challenges and opportunities, and concrete next steps that technology providers, human rights organizations and social media communities can take to make the power of video-for-change safe, ethical and effective.

Die Revolutionen gegen die alten Herrscher in diesen Ländern kamen jedoch nicht von heute auf morgen. Sie sind in den vergangenen Jahren heimlich gewachsen – im Internet. Vor allem die Revolutionen in Tunesien, Ägypten oder in Bahrain sind auf die rasante Verbreitung des World Wide Web in diesen Ländern zurückzuführen. Die steigende Internetnutzung ist einer der Gründe, warum es gerade in Tunesien und Ägypten zu den ersten Revolutionen im arabischen Raum kam. Meinungsfreiheit und Meinungsvielfalt – im Netz ist möglich, was dem Volk durch das Regime untersagt ist. Gerade in Ägypten gab es ab spätestens 2005 eine große Zahl an politischen Bloggern. Sie schafften ein Meinungsbild in der Gesellschaft und haben dazu beigetragen, die Revolution und den Sturz des Mubarak-Regimes vorzubereiten. Warum ist das Internet für die Volksbewegung unverzichtbar? Und welche Rolle spielt der arabische TV-Sender Al Jazeera?

description: Regular talk in the form of a series of linked lightning talks. We would of course like some time for questions. Could eat up a one hour block with 5 min Q&A after each 5 min talk? (This would mesh better with RiverTV than having all the questions at the end? We’d love feedback and discussion: Much of this is work in progress. * Jinc-windowed Jinc clamped Elliptical Weighted Averaging: A superior alternative to Lanczos Sinc-windowed Sinc filtering Several improvements to Heckbert’s EWA method have produced a filter with the desirable features of the classical Lanczos filters. The method, suitable for demand-driven systems (GEGL, VIPS…) will be described, its strenghts and weaknesses stated, and comparative results involving image enlargement and reduction, computed with the ImageMagick implementation, will be shown. * High quality automated JPEG thumbnail and reduced image production with adaptive prefiltering JPEG is still the format of choice for the electronic transmission of small and full size versions of natural images. At low quality levels, however, its block and ringing artifacts reduce its edge over JPEG2000 and dithered PNG8. These artifacts can be reduced by increasing the strength the lowpass filter used to reduce the size of the image. ImageMagick examples, illustrating these and other ways of maximizing bang for the buck, will be discussed. * Nohalo subdivision with Locally Bounded Bicubic finish: A halo free upsampling method LBB-Nohalo is a novel halo-free resampling method which can be roughtly described as an adaptive blend of Hermite and Catmull-Rom interpolation. The method, suitable for demand-driven systems, will be described, its strenghts and weaknesses stated, and comparative results involving image enlargement, computed with the VIPS implementation, will be shown. * Jacobian adaptivity: How to smoothly blend a resampling method tuned for upsampling with one tuned for downsampling Suppose that you have a favorite sampler tuned for upsampling, and a favorite sampler tuned for downsampling. How do you “”blend”” them so that the “”right”” one is used, yet without “”switching”” artifacts when warping goes from up- to downsampling within an image (as can happen when performing a perspective transformation) or in different directions at a single point (like when resizing by making the width smaller but the hight larger)? Answer: Blend depending to the singular values of the Jacobian of the transformation at the point under consideration. Details will be provided, and GEGL results hopefully shown (still coding! the machinery is built into GEGL but no high quality sampler currently uses it). * The hacker’s guide to the computation of common resampling filters and related geometrical quantities Several simple but little known formulaic simplifications for common filters (bilinear, Catmull-Rom, Blackman, …) leading to speedups will be presented. Most have already been implemented in ImageMagick and VIPS. In some cases, calling them directly is faster (and more accurate) than using Look Up Tables. Another example of simplification: Highly efficient trig.-free computation of the smallest ellipse containing both the image of a disk by an linear tranformation and the disk itself, and computation of the containing parallelogram with horizontal top and bottom sides. * Highly accurate polynomial approximation of windowed-Sinc and windowed-Jinc filter kernels The Boost C++ minimax package can be used to produce fast and highly accurate polynomial approximations of non-polynomial filter kernels. Examples involving both the Sine and Bessel versions of Lanczos 2 and Lanczos 3 will be given. Similar approximations are used by ImageMagick.

Data Viz: Open Source and Sources

description: The main question with data today, is not so much their existence but what is processed, their continuous use and applications,”” said Jérémie Zimmerman from La Quadrature du Net, a French organisation that aims to defend the rights and liberty of Internet users. Today, data is everywhere around us. They were around yesterday but we did not have the means to work with and visualize them on massive scale before. Thanks to the Internet and the value of sharing and transparency engendered by its long-time users, we can nowadays access and find tools to process massive amounts of data and reveal information that used to stay hidden in lists of numbers. On one side, companies, governments and media put more and more datasets at our disposal. On the other hand there is more and more specialized and specified softwares that are provided to treat and visualize this profusion of information, and many of these tools are indeed, open source. To play on words, information sources could be considered as “”open sources””. Like never before, anyone may gain access to a significant amount of raw information via an Internet connection. Of course, not all of the datasets are available and sometimes we would prefer this raw information to be delivered at in better formats, but so much is ready to be cooked. In terms of expertise, datasets and softwares are no longer just the turf of scientists and journalists, artists and amateurs are exploring them. The increasing number of data-visualizations produced by people or making platforms that help people to create their own visualizations is an emerging tred. This presentation, focuses on data visualization. It puts in perspective the notion of information and its possible changes in this “”open sources”” world. The presentation of several examples taken in from media and some artists portfolio is shown, as well as paths for audience to get involved. Etymologically, information is what is put into form. Does the fact that we can all potentially process databases, extract meanings out of the information and visually represent data thanks to open source tools, modify the shape that information used to have and the how we used to interact with it?

She is also author about Inkscape book in french and docwriter on the french team of Inkscape. Cédric Gémy is a french graphic designer, teacher, art director, author (etc etc) about many floss graphic. He is also docwriter in some floss graphics. Cédric and Elisa have founded the new Association Floss Manuals Francophone, the french localisation of the fondation Floss Manuals. Floss Manuals is a fondation creat by Adam Hyde. Adam Hyde was a digital artist come from New Zealand. Now he manage Floss Manuals and Booki for creat new free and good manual about free culture and free tools. "Jon", "Phillips", "Fabricating a Libre Graphics Future", In art school we used to say there are people who work on themselves and those who make art. While this reductive analysis can’t possibly explain the complete path for promoting and growing development and usage of libre graphics software and ideologies, this presentation examines the two paths of conservatism and progressivism through several examples. From desktop vs web development with Inkscape vs Aiki Framework, software vs hardware with flickernoise and the MilkyMist1, and fixed-income vs dynamic business growth, both defensive and offensive strategies for the future of Libre Graphics is shown. Of course, the bias in this presentation is to grow the creative free software applications and libre graphics projects globally in the face of mass competition from locked-down creative web applications, the rapidly decreasing cost of consumer electronics for producing and consuming digital media, and possibly the largest threat to ourselves, the lactic acid of infinitely supporting legacy architectures of hardware, software and mental processes.

In this presentation I will quickly introduce why color management is required, and also the problems introducing an integrated color management workflow. We will compare and contrast the frameworks commonly used in OSX and Windows 7. By discussing the integration points, we will be talking to application developers and platform maintainers in order to shape the future development of colord and the front-ends such as GNOME Color Manager. We will also spend some time exploring the intricacies of an open source color management framework best suitable for display, scanning and printing, and how we can start to provide this functionality. I’ll cover how key projects have already been modified to work with colord, and what application authors still have to do. There will be time left for questions and discussion. It is expected the audience will be moderately technically skilled, and possess a basic understanding of color management.

While I was in London returning from Brussels, I received a call from the San Francisco Art Institute to teach a freshman foundation course titled “”Making and Meaning””. It was the first time I had the opportunity to create my own syllabus for undergraduates, so I chose to teach about free culture, and how create work and consider open principles when executing projects. Three weeks away from the end of the semester I was struck by a nearly life-ending infection. A fellow free culture advocate came to my aid, teaching in my place, and helped to produce and inspire a project called “”The Physical Word.”” In this presentation, I will share my story of how the principles of LGM serve as inspiration to recovery and regrowth.

description: As Douglas Rushkoff explains in Program or be Programmed, programming is a new literacy that ought to be mastered if you care about taking a part in directing our culture. To those who already program, it can sometimes seem odd that the number of people learning this vital skill is so small: after all, basic programming is not very hard. The catch is, programming as a skill is deeply embedded in a larger ecosystem, referred to as programming culture. To learn how to program is not just to learn how loops and variables work, but also how to navigate this culture. Like any culture there are biases in programming culture, and these can make learning how to program more difficult than strictly necessary. As a designer, there are certain biases that are especially remarkable. One of them is the way how text-based interfaces are in favour: Whereas everyone else is traipsing around picking dazzling fonts to describe their world, your nerd has carefully selected a monospace typeface, which he avidly uses to manipulate the world deftly via a command line interface while the rest fumble around with a mouse. This talk will highlight a number of ways in which the text-oriented view of traditional programming clashes with the visually oriented way of thinking of designers. It shows how text based thinking can enhance a design process, but also goes into how a bias towards text-based approaches can stifle the development process of software, and make programming less accesible to new audiences. It shares lessons learned from the process of learning to code as a designer, and subsequently teaching code to design students. It concludes with how developments in Libre Graphics software can mitigate between these two paradigms.”

Reviving public domain works is not limited to fonts, of course, so there are potential lessons for other areas of design as well.

It’s also mainly used for generating profits and not for helping people. FLOSS is nice, but it only covers software. Wikipedia is nice, but information is not enough to use a technology. CC-licensed art is nice, but it won’t fill your belly. Today, despite all our technology, a large part of mankind does not have sufficient access to clean water, food, energy or shelter. This talk sketches the idea of a public database for sustainable technological processes and sufficient information on how to implement them.

Explanation: Although Nicolas is prepared to do a live programming demo, this would not work well with river-valley.tv, hence the pretending. In addition, slides allow appropriate zooming on the action, which will make things easier to see, and allow for the insertion of useful comments. After completing his PhD in Theoretical Computer Science at the University of Kent, John Cupitt spent 15 years in the Scientific Department at the National Gallery, London, as the Gallery’s colour and imaging specialist. He was lead software developer on projects that built multispectral, visible, infrared, x-ray and 3D scanners for art objects. He designed and programmed the Gallery’s colorimetric print-on-demand service. In 2004 he moved to Imperial College, London, to work as a bioinformatics modeller for the analysis of FDG-PET images of COPD and asthma patients. He has published papers on camera calibration, image processing I/O systems, user-interface design, the measurement of colour change in paintings, infrared imaging of paintings and on the analysis of infrared reflectograms. He is the lead developer of VIPS, a popular open-source image processing system.
