There are a few ways to follow this blog, ask questions and contribute to online discussion. The ones below are already set up: please let me know if there is some other forum you would like to see included.
There is a Piazza discussion group for APL. If you have already used Piazza for other courses then you should be able to subscribe right away: otherwise you will need to create a new account.
Link: Piazza group APL16
The course mailing list is firstname.lastname@example.org. You can use this to send mail round all APL students. Access is restricted, so you will need to send from your university address s….@sms.ed.ac.uk.
This list will be used for announcements about the course, so please make sure you read mail sent to your university email address.
