(re)search addicted

when we seek, finding something isn't that important. our "seeking system", as jaak panksepp calls it, doesn't seek for reward per se.

Its prototype is foraging behaviour, the search for resources – food, shelter, a mate etc. Its chemistry is characterised by dopamine, a neurotransmitter described as the ‘power switch’ because it turns on, energising and invigorating the individual in relation to their environment. Dopamine is similar in chemistry to cocaine, and it has the same effect on the individual – creating states of high arousal and focus. In animals it is quickly spotted: sniffing and persistent forward locomotion are indicators of the SEEKING system in action. | panic, seeking and playing

jaak panksepp, interesting yet controversial research and books, ie affective neuroscience

the seeking system is sensitized by (1) regulatory imbalances to yield general arousal and persistent forward locomotion (terry winograd once also talked about locomotion) and (2) external stimuli that can be either have strong or weak interactions with this emotional system and (3) it helps mediate appetitive learning so that the animals will become eager and exhibit expectancies in response to cues that have been previously associated with arousal and disarousal of the system. | p 146

we don't know what we are seeking for or: if rats go shopping:

dynabook, 40th anniversary of an idea

it may be 50 years that people don't have to share a mashine, the american computer history museum suggests, using it somehow as a definition for the personal computer. they organized a celebration where they invited alan kay to talk about dynabook. or as kay states: "the power of the context" and the "40th anniversary of an idea". it's actually a talk about heroes and landmarks in computing. recommended (if you ignore the moderator) | pointer via mivsek.

one think worth to celebrate is 40 years of engelbart's demo he gave at the 9th of december 1968. 3.45pm.

50 years ago: john mccarthy with lisp.

1962: the romance of interactive computing began with sutherland's sketchpad;

its the linc (wes clark, 1962), alan kay would give his vote for as "the first true personal computer", having the quote of wes clark on his slide: "the user should be able to see over the computer."

there have been lots of "single computers" around already in the mid 60's.

once i had a question about KiddieKomp, dynabook and notetaker. but i didn't ask alan kay, i asked adele goldberg instead ... hope she was invited, though.
