Free online file conversion tools

Free online file conversion tools

Though still in beta, these two online services do a good job at file format conversion. Zamzar is a multiple format file conversion tool,  supporting not only conversion to/from Microsoft and OpenOffice formats, but also various graphics and audio formats! See here for a complete list of all formats supported. Vixy on the other hand is a lot more specialised – it converts  FLV online video files (including YouTube ones!)  into downloadable files of various formats for your computer, iPod…

Opening a door with a credit card

While I’ve always seen it being done on TV and in the movies (even on supposedly modern locked doors!), I’ve never actually been able to open a single door using a credit card.

DrupalEd – Drupal for Education

DrupalEd – Drupal for Education

Nice to see an education-specific distribution of Drupal released. DrupalEd EdtechTalk has a thorough Screencast Tour of it here, and one can also create an account at the demonstration site here. From what I’ve seen, this system looks very clean and easy enough for end-users (i.e. busy teachers and students). Not sure about ease of installation or backend management though.
