Class 24: Silk Road

Posted: Mon 13 April 2015


Each team will have an opportunity to present their project the last three classes (April 20, 22 and 27). The schedule is here.

Note: due to a bug in slideshare's updated player, ink markings no longer appear in the viewer.
If you download the slides, they are present though. Hopefully, the player will be fixed someday.
