Tech-centric human rights group Access has published a handy primer for those looking to participate in a Middle Eastern or North African revolution (and keep their identities private while at it). You know—those secret police are assholes.

The guide could be a huge boon for would-be dissidents who might otherwise be too scared for their lives to participate in democratic upheaval. But this is really great stuff, neatly organized—how to access blocked sites, use encrypted chats, text securely, and a lot more. Props to Access for doing something more with the internet than propagating cat videos—this guide could literally save someone's life. And maybe help boot a dictator, too. [Access]
