Tangled cables

First teaching session of the new semester today.  It was an online course and it was great to welcome part-time students who were in blue skyed carribbean towns, at work in a busy office or on their way home on public transport in Hong Kong.  I had booked a small meeting room so I didn't disturb the whole office. There's always a fair amount of cable swapping and testing needed before the session to make sure everything works with my surface. All was well this afternoon and hopefully I've returned all the cables to their rightful slots for anyone using the document scanner tomorrow.
