The latest online course venture, from Stanford professors Daphne Koller and Andrew Ng, aims to "flip" university lecture halls, leaving more time for "meaningful and engaging interaction between faculty and students," while freely sharing the prepared digital lessons with the world. Currently there are 16 courses slated for this winter and spring. Among them is a class on entrepreneurship by lean-startup demigod, Steve Blank. 

RoboBraille is an email service which can convert digital text documents into either Braille or audio files. It is quick and easy to use RoboBraille. You simply send an email with an attached text document to the specific RoboBraille e-mail account that suits your needs. Or you can upload your file by using our web interface. Both ways you will receive the document back from RoboBraille in the specified format - an audio file, for example. You do not need to install expensive and complicated software on your computer to use RoboBraille. It is free for non-commercial users to use RoboBraille. Many RoboBraille users are visually impaired or dyslexic individuals who use the email service for work, study or past-time activities. RoboBraille has also been taken on by teachers, commuters and other users who can benefit from accessing digital text documents in alternative formats.
