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.

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.

Vocoder (Voice Coder)

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.

Sampling

Some weeks ago, I was discussing the term sampling; it was of course in relation to electronic music. I’m not into sound or music and my take on the conversation was that sampling is part of visual media too. My argument is that taken as a three-dimensional object, the moving image needs to be sampled to be experienced. Two axes of the object are the spatial coordinates x and y, and the third axis is time. Thus, film samples the moving image in the time-axis at 24 images per second; analogue video and digital video add to the sampling the spatial coordinates. However, the reorganization of a particular beat or sequence of beats of music to produce a new composition, rhythm, or even musical genre has no counterpart in the moving image media. One could argue that the narration and even framing or images of a particular film of video are remixed producing thus new productions. This is done all the time in cinema and more conspicuously in T.V. spots. This however is different from sampling and follows the logic of remix and media quotation (remediation?). When there is a case of visual sampling it is the sound that creates the rhythm, not the moving image.

Visual sampling? Close your eyes and see if you miss the images.
