20:30 < Shred00> so a reasonable fall back is being able to take an estimate based on the speed you hope to drive on certain types of roads.
20:30 < curious> yeah, but point is... calculating ETA is damn complex , and should be quite external from navit because
20:31 < curious> navit does NOT block way for such software
20:31 < curious> it allows live updates of map state
20:31 < curious> and this is quite enough
20:31 < Shred00> so, is there some documentation on this "external" interface?
20:31 < curious> read on 'traffic distortion'
20:32 < curious> there is no 'interface' - you provide just distortion.txt file which is included when re-calculating route
20:32 < curious> it can include all way of distortions
change of axis?

- Updated the TomTom software on TomTom Home
- For using OSM, in the navit.xml map section map type has to be modified
with either the exact name or *.bin
- During debugging these coordinates are retrieved from the navit.log http://www.google.com/search?client=ubuntu&channel=fs&q=48.133333%2C11.566667&ie=utf-8&oe=utf-8

27.3.2011. Meeting with Fawn Ellis, student from TU Delft, who does research on user behavior and the relation between people and interfaces, in the broadest sense. Research of this type is conducted in order to solve usability problems, and see how people feel when in direct contact with an interface, in order to improve design. In this research, people are either asked specific questions, or left to freely experience an interface, and afterwards asked how was there experience, what did they feel and why. It is important to have consistent groups ans ask consistent questions, not based on assumptions. From her experience the best people to test products on are the ones who have no experience. The ultimate goal of usability is offering people the feeling of control.
The most recent problem with Navit on my TomTom go 300 is the failure of loading maps, which cannot seem to be solved

Compiling Navit on TomTom go 300.
January
The decision to use a GPS device, and not a mobile phone came from the distinction between the two devices, the first being a multi-purpose entity, and the other serving as a device for a specific cause, diverse applications for phones are being built every day, and the gps device is closed source in more ways, because it has one purpose, to lead the fastest way from point a to point b, it is direct, useful, beneficial, it is an orientation and guide to completely surrender to (it is not interrupted by anything other than the lack of connection to a satellite)
Notes from tutorial November 8, 2010.
Before the tutorial with aymeric, I was considering the different interests that I have, and how to clarify what are the places where magical thinking comes into place in relation to technology, also which subjects am I particularly interested in. One approach would be observing elements of magical belief and elements of technological usage, finding the possible common points.
Things to use when writing:
- Describe the project and the desired outcome
- describe some previous projects
- describe what you want to do
- describe why you want to do it
- describe how you intend to achieve it
- describe the success criteria for this project
October
If I focus on new magical thinking, or a magical understanding of technology, the goal of this project would be to try and find a way of implementing it into my interest of navigating through information layers in the city.
Some things to look at:
cloud as a metaphor for mystifying data
tantalum chemical components in devices
i-phone suicides
Graham Harwood and his work on hardware energy
"The internet space, or the interactive space becomes so fractal, that we see things working on one level, that are self similar on the next level and self similar on the level after that. So once experienced in learning in a viral space, on a genuinely memetic viral space, a self similar space, is no longer through the traditional teaching stories of the Bible. We communicate through pattern recognition, rather than through teaching stories" Douglas Rushkof

Keywords: paranoia, procrastination, wild-domesticated, intuitive technology, spam, how does technology implement in popular culture, self referentiality, theories of conspiracy, vocabularies, concept of keywords, skyping, filtering, the Internet of things
Starting ideas:
Possible continuation of working with locative media in city spaces (the not realized element of my third thematic project), researching how does information shape spaces, and how do these layers of information communicate with space and with each other. How do we navigate through physical information?
animal-human-city how are animals perceived, what happens when the city is perceived as their natural habitat, antropomorphizateion of animals (pets), what belongs to "the wild", and what is "domesticated" in human-animal behavior. Where is the space of animals and who claims what. animal as meat, people as animals.
procrastinometer-a tool for measuring anxiety, unproductivity and frustration in today's working and living environment. How are our health and sanity affected by the shift of the working space
in combat with online semantics
software that measures key markers in, for example, youtube videos, through speech recognition
-prototype of a good internet citizen
-customizing vocabularies of browsing
