Week 1

Alan Turing's Universal Turing Machine (UTM) http://en.wikipedia.org/wiki/Universal_machine

was a concept for an infinite loop of tape that seperated into frames, each frame would present a different state. This created an infinite programming potential for reading. 

deconstructing the seamlessness of the factory line. The pipeline.

in the afternoon we played with Turtle.

stuff to do & Resources - start fetching data from the twitter api https://code.google.com/p/python-twitter/ http://pzwart3.wdka.hro.nl/wiki/PythonTwitter http://www.lynda.com/Python-tutorials/Up-Running-Python/122467-2.html

Week2=

In the morning we looked at SVG files, and how you can edit the xml of them in a live editor within inskape. You can also execute python commands by pasting in python drawings and the vectors will be generated within inskape.

In the afternoon we looked at making api grabs , loading them with Json libs

ajax.googleapis.com/ajax

add json extension for firefox

Json turns xml into a javascript object.

json has lists - lists [] append("milk")

and dictionary {} foods = [foods["chocolate"] = "love to eat it"]

runcron - can execute pythonn scripts from a server timed.

i got my twitter search function to write to a text file. Im going to look at automating that text file to network printer for this cloud project.

This script prints a json grab from twitter api, loops and sends to printer every 55 seconds.

week 4

basic arithmetic (moving the digit to another column when u reach *power 10*) keeping the count. binary systems would use 10 figures ( 0,1,2,3,4,5,6,7,8,9) and then when it gets to 10 will give to another cog to start counting giving you an infinite counting system. The difference engine

George Boole began implementing numerical binary into text in logic. He is the inventor of what is known as Boolean logic, true and false statements and conditionals.

Lewis carroll wrote logic conditionals in alice and wonderland "It is a very inconvenient habit of kittens (Alice had once made the remark) that, whatever you say to them, they Always purr.  'If them would only purr for "yes" and mew for "no," or any rule of that sort,' she had said, 'so that one could keep up a conversation!  But how can you talk with a person if they always say the same thing?' Lewis Carroll (1832 - 1898)

Alice predicament allows us to talk with computers. Alice's whole adventure is based on encountering scenarios and applying logic conditionals.

8-bit = 8 on and offs. giving you 255 characters to allocate. all commmands are distributed via the ascII table. http://en.wikipedia.org/wiki/ASCII unicode (utf-8) (UTF-16) Think about the task of the translator by Walter Benjamin/ Everything is interpreted. every webpage is being encoded all bytes are counters for their 8 bit reference gives them a Glyph. see last years page for more on human computation http://pzwart3.wdka.hro.nl/wiki/Human_Computation_(Slides) PYTHON AND AUDIO wav files have a header like how utf is encoded at the top of html. (16 bit little endian , rate 44100 hz, stereo) number of samples / sample rate = time of piece. using this example http://zacharydenton.com/generate-audio-with-python/

This code generates a sound byte the same frequency as the temperature of Rotterdam that day.
