cloud computing clarified
after a vigorous discussion at a retreat in the castle yesterday, experts from Xensource (now Citrix) were able to help me understand what Cloud Computing is all about.
Basically, high up in the earth's atmosphere, there are these grey or white amorphous blobs of droplets of water and ice - there are officially ten types of these objects,in the now classic Hamblyn scale, ranging from Linux Nimbus, through Windows 7 Stratus and on to OSX Cumulus and finally down to TinyOS Pryoumulus. Some of these condense on
small intel ice particles, while others appear to be dropets of pure AMD.
The presence of very small particles of silicon in these droplets was made possible by the UC Berkeley research into so-called "smart" "dust", and followon work in Scotland on "speckled" "computing". Originally, it had been envisaged that these arrays would be used for weather prediction - indeed, one large storm grid was run for a while to detect or predict the weather, but then it became clear that self-fulfilling prophesy was the way to go, and the systems were used to control and pre-set ratehr than predict Internet weather.
However, early cloud computing was confusing and difficult to programme - much like the weather, it had a mind of its own, and was prone to chaotic, and even catastrophic
outcomes.
So then along came virtualisation. Now instead of a vast array of different clouds, we can now report that every cloud is controlled via its silver lining.
The wisdom of the Cloud is now commonplace. The layered architecture, with
clouds at ground level providing isolation through fog, while cloud 9 at the highest level presents an ecstatic API to the user, is complete. Many users are no longer at sea when the use the Cloud to access Ocean store services.

The Wisdon of the Clouds
aside from the wonderful novel, cloud atlas, we
have to put up with the latest internet fad in
cloud computing
but enough about xen - now
how to compare two competely different network architectures?
think about these:
1. internet & telephone
2. road and rail
3. food chain, family tree
4. social network, circulatory system
what is common and what would be a category error to try to compare?
a) user perception/mental model
1 - computers transfer information around v. humans communicate with each other
2. I can drive my car from a to b v. i get to sit and read a newspaper
going from a to b
3. a eats b eats c v. a begat b begat c
4. I know she thinks he hates her v. blood gets oxygen to let ADP/ATP
changes work so muscles can do things
b) economics
1. anyone can put any information application anywhere and everyone
else can use it - k*n^2 scale in income v.
I can call you or you call me....
2. road infrastructure is there, everyone has own vehicle v.
track and rolling stock are both infrastructures.
3. you need constant supply of food, so there has to be breeding as
well as good chain v. you convert O2 to CO2 so you need plants to do
CO2 -> O2 ,or we are in trouble - i.e. mutual dependency
4. If I know who relates to who and context, I can advertise right
good and services to them
c) technology
1. smart network + dumb edge, v. dumb network + smart edge
2. expensive wasteful car v. efficient rail, + user choose when to go,
but not control journey time, v. operator chooses when to go and
control journey time
3. biosphere v.
4. facebook and internet v. arteries and veins & heart
d) complexity
1. need moores law for end systems to keep going,
v. telephone service becomes marginal profit business
2. if oil and safety cost too high, individual car ownership bad idea
whereas if cheap, rail isnot worth infrastructure costs
3. food chain is exponential complexity, family tree is just
logarithmic
4 social net structures follow power law - so does artierial system
e) application/intended use
1. phones were origianlly thought to be useful for music (less
interference than radio) whereas internet was originally intended for
command and control and distributed community for US army.
2. road were for armiens to invade places - rail for industrial
revolution working class to go on vacation.
3. predators and prey...

proving the existence of google^H^H^H God
maxwell's demon sits at the entrance to heaven and asks you if you have free will or not
if you do, you go to hell - if not, heaven
if this is not true, there is no good. if it is true, there is no argghhhH!!!!!

lily allen admits...
...she doesn't "get" the rolling stones - all I can say is that the 72 live version of
Love in Vain sends shivers down my thing - Mick Taylor slide + keef and mick vocal/guitar is awesome
but really the meisterwerk is Exile on Main St.....definitive R'n'B

et in arcadia, placet
went to a talk at wolfson about publishers views on the academic world of stuff in the digital era -
basic premise is that:
past/once upon a time, a publisher was the venture capitalist of gutenberg
then/now (recently) they turned into the bankers of the journal/monograph era
future/where they'd like to be is the tax inspector of metadata...
sort of...

william gibson continuity error
In all tomorrow's parties
gibson refers to Rei Toei
as post human at one point.
here is your starter for ten:
why is this the wrong term for an Idoru?

special relationship
milliband(pede) and clinton (unhilarious) renewed the special relationship between the U[K|S] today = yippee - we are still in "special needs" and we can follow the US into war, be their european aircraft carrier, missile launch site, and supporter in all things
financially reckless.
I am so proud - it is so consistent with rolling over and letting foreign companies ship their exploited workforces here to work underpaid, underprotected AND displace local workers.
Just WTF is going on with people these days? have they no spine? how did we end up in this craphole?
civil rights, finance, services, just which policy (and mechanism) did anyone actually vote for (n.b. I have never voted for either major party in England since 1976 - although I voted in every election -)
stand up and be counted, you moron thatcherites and new labourites.
