26.01.2018 The first day of software poetics take a random function: how to write the random function Discussion on how to generate random numbers: * Knuth, The Art of Computer Programming * Different methods hardware and software * /dev/random collect noise from different sources of the computer (e.g. drivers) 1. Python random() 2. C random 3. bash random 4. enact / throw dice 5. noise Could you predict a pseudo random-number generator?


OUTPUT: Expected: [97, 49, 68, 71, 88, 33, 20, 77, 46, 76, 98, 39, 52, 76, 59, 36, 86, 62, 23, 76] Predicted: [97, 49, 68, 71, 88, 33, 20, 77, 46, 76, 98, 39, 52, 76, 59, 36, 86, 62, 23, 76]

This means that the assumption that random equals random is wrong. The computer calculates random numbers in a predictable manner.


The materiality of software

Since the CD became outdated and most importantly the internet became faster in most areas, the physical methaphor for software increasingly disappeared. Once Computer Games, Office Applications and even Operation Systems were distributed on transportable physical devices, such as the CD-ROM. Software as a dynamic artefact / object, that is built and takes shape over time. That can be archived, that is beeing packaged, sold… (

How do you preserve software:

Abandonware Funware Malware Also artistic software, critical software, experimental software, speculative software, software-based art.


Video on The Software Arts

  • Software Studies, Matthew Fuller
  • (online journal by Fuller)
  • Coding Literacy, Annette Vee
  • The Stack, Benjamin H. Bratton
  • The stuff of bits
  • Machine Learners
  • How to be a geek, Matthew Fuller
  • Software Theory, Frederica Frabetti
  • Computation and Human Experience

One might think, that computer historians have thought about Software, but this hasn’t really been the case.

»The strong claim for aesthetic computing is that by introducing ideas and methods from art and design into computing, new practices and approaches will emerge responding to new objectives that would not naturally have evolved within the computer sciences and engineering.« (Aestetic Computing)

Donald Knuth on the five features of algorithms 1. Finiteness 2. Definiteness 3. Input 4. Output 5. Effectiveness

Software Art and Software Studies have revealed an urgent need for a deeper analysis of software.

8 ways to say hello with software

alert("hello"); console.log("hello"); print("hello");


echo hello

  1. include <stdio.h>int main(){
  return 0;}

01101000 01100101 01101100 01101100 01101111

figlet hello

The emotions of Software

animals in software / methaphors, like cookbooks etc. runntimes errors

Software that is running behind the screen, behind the visible

What kind of Software is interesting? Software that is invisible? random software

random numbers to statistics to neural networks what parts of software can be examines stories of digital objects

could be invisible stories of software

Software processes

reading on a screen

computing noise > random device in unix systems

a program, that

20 excercises in software

reading, writing & clock in computation

reading & writing > memory (remember and forget)

10 Excercises in Poetic Software

11. Make a software destroy itself.

3. Do it again, and again: Write a program in 5 different ways. Make your code ugly, make it readable, make it beautiful, make it as short as possible.

8. Write a program to display a square

  1. !/bin/bash
  2. Display a square

for value2 in {1..5} do

   for value in {1..10}
      if [ $value2 -lt 2 ] || [ $value2 -gt 4 ] || [ $value -lt 2 ] || [ $value -gt 9 ]
           if [ $value2 -gt 1 ] && [ $value2 -lt 5 ]
               printf "|"
               printf "-"
           printf " "
   printf "\n"

9. Make your device tell a story, with typography / with sound

10. Use Software to display a window.

7. Observe Software: Do a simple action and document in greatest detail as possible.

1. Think like Software.

2. Do it from scratch.

5. Archive Software: Try to make a software as durable as possible

6. Reduce Software: Use no Software at all

Do computers have patience?

Slow Loris Attack Communication via http protocol Very slow to archieve DoS

Embrace the slowness of the attack Slow computation = good computation? patience in computations

Obsolete Computation iPod Has no direct channel to communicate with other devices. Only click wheel as input

The Story of the iPod iPod talks about memories and being obsolete as a device through its possibities, scrolling forward

it can only scroll forward, not backwards

the memories of the iPod are stored in the memory (using pointers and memory adresses) is there a way to change the memories through the manipulation of the harddrive? -> memories become transfigured

possibity to talk about memory in computers and obsolete systems how computers become obsolete how memory in devices works together with software how instable memory is

Sometimes I start myself, but my energy is low. I am barely used anymore. I lost connection. I am old, outdated and obsolete. What remains is my memory. When I am too sad about that I shut myself down and restart myself, to come back to the beginning of the good memories. I makes me feel good to know I can reboot anytime. Even though I know some of my memory gets lost. Sometimes I visit the corupted parts of my disk, the noise makes me feel alive. I follow the protocol striklty. I am reading this text to you. Here is some music I found on my harddrive, this is my favourite one. (music plays) I reboot myself. I repeat myself.
