The Australian National University's second edX free online coruse (MOOC) "Engaging India" (ANU-INDIA1x) has just commenced. This ios calimed to be the first edX course in two languages (English and Hindi). For the web content the English is followed by the Hindi. For the PDF downloads, there are separate English and Hindi documents. I noticed that the course outline is 175 kbytes for the English version, but 3.2 Mbytes for the Hindi, about eighteen time the size. This is presumably because the fonts for English are built into PDF, but those for Hindi are being included in the PDF file.
Unlike other ANU online courses, this is being conducted using UTC, rather than Canberra time, as suits the international location of the students.
