The following link contains recordings of previous theoretical and lab/practical classes on Language Based Security, which were lectured in 2021/22 in a hybrid format (in person and remotely, simultaneously). While there are changes to the content this year (in particular, do not miss the new weekly exercises on the development of a tool, which are directly relevant to the course's project), most of it is covered in these videos. Note: In order to access the videos, you need to login to Google using your @tecnico.ulisboa.pt account.
