Media archaeology-based Visual Music

This article describes the intersection of Media Archaeology and Visual Music in my artistic practice that repurposes obsolete devices to investigate new connections between light and sound. I revive and hack tools from our analogue past: oscilloscopes, early game consoles, and lasers. I am attracted to their aesthetic difference from the ubiquitous digital projections: fluid beam movement, vibrant light, infinite resolution, absence of frame rate, and line-based image. The premise behind all my work is the synthesis of both image and sound from the same signal. This strong connection envelopes the audience in synchronous audiovisual information that reveals underlying geometric properties of sound. In this text I describe the practice and the aesthetic potentials connected to few analog and digital hybridized systems to generate new sonic and visual experiences.

The Hybrid Color Film: Multiplicity of Space, Time, and Matter

Hybrid color films of the 1920s such as The King of Kings (Cecil B. DeMille, 1927)—that is, films comprising a mix of different historical color processes—are a particularly fruitful resource for the comparison of the silent era’s various color technologies. This article analyzes these cinematic hybridizations and argues that this type of film is much more than the sum of its parts. In embodying a multiplicity of layers of space, time, and color on a literal and metaphorical level, hybrid color films are not only symptomatic of the transformation of the medium in the 1920s but also symbolic of current approaches to film historiography based on media archaeology.

THE DEEP TIME OF BITCOIN: EXCAVATING THE "WORK" IN PROOF-OF-WORK CRYPTOCURRENCY SYSTEMS

Estimates place Bitcoin’s current energy consumption at 141.83 terawatt-hours/year, an amount comparable to Ukraine. While Bitcoin’s energy problem has become increasingly visible in both academic and popular discourse (see Lally et al. 2019), the computational mechanisms through which the Bitcoin network generates coins, proof-of-work, has gone under-examined. This paper interrogates the “work” in proof-of-work systems. What is this work? How can we access its material history? I trace this history through a media archaeology of computational heat, in an attempt to better situate the intimate relationship between information and energy in proof-of-work systems. I argue the “work” in these systems is principally heat-work, and trace its ideological constructions back to nineteenth-century thermodynamic science, and the reframing of doing work as something exhaustible, directional, and irreversible (Prigogine & Stengers 2017; Daggett 2019). I then follow thermodynamic discourse through Cybernetics debates in the 1940s, illustrating how, early in the formation of Information Theory, the heat-work undergirding the functioning of a “bit” was obscured and compartmentalized, allowing information to be productively abstracted apart from its energetic infrastructures (Hayles 1999; Kline 2015). I conclude with a discussion of the heat-work within the Application Specific Integrated Circuit (ASIC), Bitcoin’s principal mining tool, arguing that proof-of-work mining is not a radical exception to the computing status quo, but rather a lens through which to think more broadly about computing’s complex relationship to energy, and ultimately, how this relationship can be different.

Intervals of Intervention : Micro-Decisions and the Temporal Autonomy of Self-Driving Cars

Self-driving vehicles do not simply translate algorithmic definitions of their interaction with the environment into material actions. In the implementation of microdecisions, temporality itself becomes an element of the success of operations. Taking the fascination for a non-human and distributed capability of decision-making as a starting point, the paper explores how the temporality of microdecisions is integrated into technical systems that interact with their surroundings. On the basis of a media archaeology of these temporalities, it develops a heuristic of autonomous technologies that explores the role of micro-decisions. With self-driving cars, terms such as agency (based on algorithms), temporality (in different intervals of intervention), decision (in reference to alternative scenarios), and autonomy achieve new meanings worthy of a re-interpretation.

Beeldvorming over archeologie, beeldvorming bij archeologen

Imaging of archaeology, imaging by archaeologists. Among the general public and in the popular media, archaeology has a quite positive image, but one that is far from the realities of the everyday work of professional archaeologists. In this paper, I explore how that biased image became established and what role media professionals and archaeologists play in maintaining it. Further, I discuss what effect the image of excavation as the central, if not the only, aspect of archaeology has and has had on the careers of female archaeologists. Finally, I argue for self-reflection about our professional identities and the way we present our work.
