Blackboard bug & various questions/messages

Posting this both at course page and in Canvas ... still. 

• BUG at the end of the lecture: top-right of the board, should be "Lin. INDEP <=>".
• I didn't outright ask you whether you wanted that workshop.  Please remind me on Friday.  
  • But if so: Tuesdays 16-18 is the proposal, and it seems easy to find rooms.  
• Q for Friday: Would you want a seminar or seminar-type session on Friday 25th?  
• Canvas question, think of it for Friday:
  Canvas supports multiple choice.  I am not too much of a fan of that format (the important thing is show your work, not be good at guessing), but 
  • do you want a few "sanity check questions" posted there?  Do not expect them to look like exam questions
  • would that affect your idea of whether Canvas should be used or avoided?
• Topic for Friday: Will start on 2018-lecture2.  An hour after schedule. 
• And finally, contact student: Olav Abrahamsen. Spamshielded e-mail-address: before @student.sv.uio.no, put "olavabra".
