- ZeitschriftenartikelForeword(Informatik Spektrum: Vol. 43, No. 1, 2020) Kelso, Patricia H.Marshall McLuhan thought that Johannes Gutenberg’s invention of movable type created the modern world. What kind of society will the Internet create? Will it be a democracy or a surveillance state, like Eastern Germany under the Stasi? We cannot have both! The Internet was developed by the U.S. Government during the Cold War to spy on foreign governments and to identify potential dissidents at home. It was explicitly designed as an instrument of espionage and control. But that was not what its early-stage originators intended, before the government took over. The original inventors were romantic peaceniks who believed that they were creating a good thing for humankind. The powerful in every age have tried to control access to information. Can the new generation of electronic technology experts devise ways to realign the Internet so that it can serve democracy?

- ZeitschriftenartikelBlockchain and society(Informatik Spektrum: Vol. 43, No. 1, 2020) Caradonna, ToniIn this text, the origin of blockchain technology is explained and put into the context of three waves of digitalization: digitalization of information represented by the internet, digitalization of communities and community building tools represented by social media and digitalization of value represented by blockchain. The text will show that blockchain can bring back promised features of digitalization of the first two waves, features that were lost with centralization tendencies created by business models that are independent of the underlying technology. After a short introduction to the terminology, a map of the potential blockchain has for society is sketched. The text also debates the decentralization aspects of the technology and the challenges it poses for individuals and organizations. Later, the storytelling aspects, as well as some religious aspects within and around the blockchain community are analyzed. Finally, some thoughts about adoption scenarios are laid out, and some ideas why blockchains have become very important in Switzerland are formulated. The focus of this text is on the opportunities and strengths of the technology. It deliberately oversimplifies the technological aspects in order to focus on the implication of the technology on society.
- ZeitschriftenartikelDemocracy and the language of power(Informatik Spektrum: Vol. 43, No. 1, 2020) Stone, RobData is a language spoken and transcribed by those without literacy. A form of capital produced by those without knowledge of its production. Our data has become a language owned as a capital. The concentration of ownership over “data capital” has created an unprecedented asymmetry of information and economic power; which calls into question the viability of a political and economic democracy. Meanwhile, we are presented with a singular yet temporary opportunity to take back ownership and control over the new language of power by claiming ownership over the productive power of the data we collectively serve to create. The following essay seeks to examine (a) the distinct nature of current technology platforms (b) the network effects at work within such platforms (c) the implications of replacing a platfrom owned by “absenstee” shareholders with one owned by those who comprise the platform/network.

- ZeitschriftenartikelMemristoren für zukünftige Rechnersysteme(Informatik Spektrum: Vol. 43, No. 1, 2020) Fey, Dietmar Fey; Karl, Wolfgang; Ungerer,TheoAls Memristor bezeichnet man eine Klasse von elektronischen Zweitor-Bauelementen, deren Strom-/Spannungsverlauf eine zumeist durch den Nullpunkt verlaufende eingeklemmte Hystereseschleife aufweist („if it’s pinched it’s a mem- ristor“). Memristoren bieten interessante Eigenschaften wie hohe Speicherdichten, niedrige elektrische Leistungen beim Schreiben und Lesen, Multibit-Speicherfähigkeit und CMOS-kompatbile Herstellungsprozesse. Darüber hinaus lassen sich Memristoren nicht nur zum Speichern, sondern auch zum Verarbeiten von Daten nutzen. Memristoren werden zukünfti- ge Rechensysteme auf verschiedenen Ebenen verändern und mehr in Richtung hin zu Speicher-zentrierten Architekturen verschieben. Dies beginnt bei noch weitgehend konventionellen Ansätzen wie den sog. Storage-Class-Memories, einer neuen Speicherhierarchieebene zwischen Arbeits- und Hintergrundspeicher, und endet bei unkonventionellen Near- und In-Memory-Architekturen, in denen Speichern und Verarbeiten von Daten ohne räumlich große und damit vergleichsweise Energie-intensive Datenbewegen zwischen Prozessoren und Speicher stattfindet. Ferner bieten Memristoren durch die dem biologischen Vorbild eines neuronalen Netzes weitgehend entsprechende direkte Nachbildung von Synapsen als flexible elektrische Widerstände vielfältige Möglichkeiten zur Realisierung neuromorpher und biologisch-inspirierter Schaltkreise und Architekturen.
- ZeitschriftenartikelUser trusts: broad-based ownership for online platforms(Informatik Spektrum: Vol. 43, No. 1, 2020) Schneider, NathanThis essay introduces what promise a novel broad-based capital strategy—trusts serving platform users—might hold for the online economy, especially as an enabler of more widespread, organized, and democratic user accountability. It draws on lessons from the experience of employee ownership alongside emerging opportunities for other kinds of broad-based ownership structures. User-oriented trusts could enable meaningful co-governance and profit sharing among essential stakeholders, a prospect that merits research and experimentation.
