How does the internet see you?

Personas is a fun project created by Aaron Zinman (along with the Social Media Group at MIT) that allows you to see how the internet views your particular name/alias (in this case, I entered “Doobybrain” and “Herman Yung” separately). Personas scours the internet for information about your name — regardless of whether or not it’s you or somebody else with the same name — and attempts to use computer algorithms to figure out the difference. The results for me were mixed each time I did it, but I think it’s still a worthy project to make note of. If anything, watching the computer figure you out is fascinating because the page turns into a plethora of rainbows.

Try it out for yourself here.

Bicilavadora: a pedal-powered washing machine

April 24, 2009 @ 2:12 pm

Students at MIT have engineered and built a prototype of a washing machine they believe to have significant impact in slums and other poor places around the world that have no easy access to water. The washing machine is built out of a standard drum barrel (shortened) and the rotating inner drum is made from identical plastic plates bolted together.

The plates are then pedal-driven by a rider sitting on a modified bicycle with chains going from the crank to the side of the barrel. Although the prototype was not a perfect success — there was water leakage on the barrel — the students think that a modified version can be made relatively quickly for the next round of testing.

As for the name ‘Bicilavadora’, it’s a combination of the Spanish word for bicycle and washing machine.
