The Great Gatsby showed me how the cars and outfits have changed, but commuting into and out of the city has not been updated much since the 1920s. Yes, bridges and roads have been improved, but it is still faster to get to certain places via car than train.

Lawrence Lessig, director of the Edmond J. Safra Center for Ethics at Harvard University, explains how our government -- given all the ways it can spy on us -- should just as determinedly use modern technology and technologists to protect our liberties.

A government that blocks its citizens from accessing The Pirate Bay (or tries to) is one step closer to being a government that also blocks its citizens from accessing a website that threatens to foment insurrection by being critical of the ruling powers or political system.

Isn't defending the former worth it to protect the latter? But we tend not to bother because we dismiss the whole matter as a debate about torrents and Daft Punk downloads. The key is to remember what is at stake.

The worldwide digital space is in danger. We, the citizens of the world, are equally in danger. We need a better and more truly democratic multistakeholder model and we want governments to be bounded by treaties to obey international law when most needed.

From Apple's legendary 1984 commercial to Google's "don't be evil" motto, the PRISM Nine have all pulled the wool over our eyes in one way or another. It is high time that companies level with us on the specifics -- most importantly where they stand on spying on us.

Wandering around the barricades near Istanbul's Taksim Square, I kept asking myself, "How could a few 'occupiers' manage to mobilize millions here and beyond, in 77 provinces of Turkey and dozens of cities in the world?"

Most brand relaunches fail under the best of circumstances, and this one is especially challenging. The fact is the MySpace brand, if it is known at all, has become something of a joke among a good of the young people they seek to attract.

Being one of the few women studying engineering at Florida International University proved to be an experience that further fueled my drive and passion for the field.
