Free science free | @jjmerelo 3 My wishlist ● Low entry threshold ● Massive scalability ● All in one system ● Fault-tolerance (except byzantine failures)

Free science free | @jjmerelo 6 What do you want it for? ● Low cost or free science ● Citizen science ● Evolutionary algorithm experiments (or any other, for that matter) ● Web science: social distributed computers

Free science free | @jjmerelo 9 Software as a service

Slide 10

Slide 10 text

Free science free | @jjmerelo 10 Almost, but not quite ● Usually freemium services (pay after a use level) ● Heroku, OpenShift, Amazon, Google AppSpot... ● There's science in it: optimize the number of requests to the server to avoid charges.

Free science free | @jjmerelo 11 Can do nothing without you ● Eventually, somebody has to lend CPU time to an experiment. ● AJAX provides a perfect environment for doing that. ● COMET (server-push) too. ● New tech: WebWorkers, apps. ●

Slide 12

Slide 12 text

Free science free | @jjmerelo 12 Free as in free speech ● The whole process must be transparent: Open Science ● People won't give you cycles if they don't trust you. ● Release early, release often, release all: data, source, papers...

Slide 13 text

Free science free | @jjmerelo 13 What have you done? ● Distributed Computing on Rails: ● Ruby on Rails + AJAX on client = Distributed evolutionary algorithms ● Experiment with up to 1000 clients ● AGAJAJ: same thing (pretty much) with mod_perl.

Slide 14

Slide 14 text

Free science free | @jjmerelo 14 EvoSpace ● UGR + UEX + Tijuana tech. ● Redis + Django based distributed evoluitionary computation engine ● Embedded wetware: valid for interactive evolution ● Now moving to Heroku

La computación voluntaria tiene su origen en el proyecto SETI@Home de análisis de señales procedentes del espacio buscando regularidades.

Free science free | @jjmerelo 7 That's why We need an object store Imagen de Michael Flick en http://www.flickr.com/photos/17773534@N03/3237000861/ Object Store en general se define por oposición a una base de datos tradicional, en la que las columnas son fijas y se estructuran en tablas que tienen relación unas con otras. Una object store, o key-value store, o base de datos NoSQL, almacena documentos indexados, habitualmente, por una clave.
