IMDEA Workshop on Internet Science

See here for titles/speakers and slides...

So far Pablo's talk had some v. interesting stuff about scaling the twitter service - clever work on solving hotspots andoverloads in memcache/mysql setup - reminded me of previous work on trying to get the IMDB system to scale - seems like these inverted databases are a pain in general, so a fundamental solution would be welcome...for those of you working on social net analysis, worry about (particularly un-self-declared) spambots in twitter - see Mowbray's talk - plus looking at Vattay'sstats talk is worthwhile
anyhow, I was reading this Future Internet Roadmap and decided that Private Green Clouds is defintely the way to go (andwe are there yet, so that is good:-)
here's the barking bit: why not put a data center in every car?

rationale:1. future cars will be electric.2. its proposed that future electricity generation will incorporate a lot of micro-generation(certainly solar here in spain, and wind in uk etc etc)3. the power distribution net is not fit for "uplink" electricity in large amount, so...4. micro-generation is largely intermittent (esp. wind, but obviously solar is at least on/off day/nite)5. hence we need to do local distribution of micro-generated power6. or else we need to store micro-generated electricty
power solution=> use electric cars as storage; to get an idea of scale, (see Mackay's book) cars could store about 30% of UK generated power -when we get to 100% of the carpool of the UK being electric...
so then where we plug cars in, why not also have a dataport too then instead of using meagre compute resource in someone's house, have a big-fat data center in the car(s) in a street - they can run off stored power when local production exceeds demand (or predicted (say nighttime) production/stored exceeds local and car demand...

the numbers should work very well...you can easily smooth day/night variation, but also short term wind variation...
before you all shout, one problem is that the batteries are really designed for a relatively small number of discharge cycles - however, some technologies (hydrogen fuel cell etc) would fixthat
so this needs 2 things.1 a smaller unit for data center2 a plan to do fiber-to-the-charging-point....

     Interesting background to talk by Nick Maxemchuk - Heilmeier (ex bell labs and DARPA programme manager) rules for research project eval:-

    What are you trying to do? Articulate your objectives using absolutely no jargon.How is it done today, and what are the limits of current practice?What’s new in your approach and why do you think it will be successful?Who cares?If you’re successful, what difference will it make?What are the risks and the payoffs?How much will it cost?How long will it take?What are the midterm and final “exams” to check for success?

    These possibly work quite well for a paper as well as a research proposal!
