Peter Sunde at Transmediale 2015

Peter Sunde words at the opening ceremony of transmediale 2015. 28 Jan 2015 HKW Berlin, Germany.

The centralised model has destroyed the internet. We’ve lost and corporations have captured us all. We even carry the sensors, mics and cameras to monitor us. Don’t play the game: give up.

Update: Sunde’s base text published on Wired UK.

Freedom in your computer and in the net

Richard Stallman’s talk at the Chaos Computer Club in Hamburg, Germany on 29 December 2014.

Freedom in your computer and in the net.

For freedom in your own computer, the software must be free. For freedom on the internet, we must organize against surveillance, censorship, SaaSS and the war against sharing.

Tool for the visualization of historical data (Chronologies)


  1. In page 563 in paragraph 1 the sentence “In recent years, research in the humanities have started to …” should be: “In recent years, researchers in the humanities have started to …
  2. In page 563 in paragraph 2 the sentence ” … because there is no way to intervene from outside the way how the program process and render the data.” should be: “… because there is no way to intervene from outside the way how the program processes and renders the data.

What is a Machine?

B17 Bomber Belly

B17 Bomber Belly. ca.1939

A machine is that which behaves in a machine-like way, namely, that its internal state, and the state of its surrounding, defines uniquely the next state it will go [1, p.261].

Thus, the material or materials from which a machine is made becomes irrelevant. As the machine becomes a function of internal and external states.

This is a short media history of technical sound coding and distortion, from the military scrambling of speech through the robotic sounds of Kraftwerk to today’s linear predictive coding burned into mobile phones.

In the sciences the combination of different types of analysis, textual and visual, contributes to the legibility of the results of the research. Techniques such as data visualization and information graphics have a long history in the natural and social sciences. Recently, researchers in the humanities have got interested in producing visualizations to synthesize facts and trends. The purpose is to create novel observations and analysis of historical and cultural data. This paper presents the use of programming and markup languages to design a custom and open tool for the creation of one particular type of historical data visualization: chronologies.

KEYWORDS: Data visualization, chronology, XML, processing.
