Slow Loris
As a reflection on the matter of speed in computation. Do computers have patience?
Slow Loris is a Denial of Service Attack. It make many very slow connections to the server and therefore fully loads the server till the limit of possible connections. This method is exploiting the way Apache server work and how they handle connections.

Memory
The iPod is an old obsolete device. And sometimes it is bored, so it explores its own memory.
The iPod explores its own memory. It is a C program that is written specifically for the iPod (using rockbox patch). It reveals the inner processes of the iPod by telling a narrative about its potential thoughts.
Active Essay
The active essay embodies my thesis in a interactive form. The text "There is no Software" by Kittler is transformed into an active and engaging form.

Publishing poetic software
How do I publish the experiments that I did together with the insights I gained about software. I made a custom writing program that enables me to interlink and make visible the different layers and and influences of software.

Notes on poetic software

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)
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/char/random.c?id=refs/tags/v3.15.6#n52
1. Python random()
2. C random
3. bash random
4. enact / throw dice
5. noise
Could you predict a pseudo random-number generator?
https://ai.stackexchange.com/questions/3850/using-machine-deep-learning-for-guessing-pseudo-random-generator
----> reverse_random.py
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Since the CD became outdated and most importantly the internet became faster in most areas,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… (https://medium.com/@mkirschenbaum/software-its-a-thing-a550448d0ed3)

How do you preserve software:

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

»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.

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
#!/bin/bash
# Display a square
for value2 in {1..5}
do
for value in {1..10}
do
if [ $value2 -lt 2 ] || [ $value2 -gt 4 ] || [ $value -lt 2 ] || [ $value -gt 9 ]
then
if [ $value2 -gt 1 ] && [ $value2 -lt 5 ]
then
printf "|"
else
printf "-"
fi
else
printf " "
fi
done
printf "\n"
done

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

Do computers have patience?

Communication via http protocol
Very slow to archieve DoS
Embrace the slowness of the attack
Slow computation = good computation?

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.
