(I’m not counting weekends.) Some of the students went to Shenzen over the weekend and discovered “an electronics mall the size of Adelaide” which was the big motivator for going. Sadly, I wasn’t able to join them at the World Cup this morning as my flight got in late and I still had marking and work to do, but here’s a picture that one of the students, Sarah, took of the crowd – and they were a very vocal crowd for 3 in the morning!
Today we finished off talking about the way that programmers work with the network when they write applications. When someone sends information too fast for a receiver, we need to control the flow of the information, but when there’s just too much information on the network (from possibly many sources) we have to deal with the congestion. Both of these (and the solutions we use) are really important reasons why the Internet works today! We had a lot of discussion, group-based work and I spent a lot of whiteboard time motivating how we could get information out of the network without having to do anything beyond what we already wanted to do, just to use it.
We had started later so students could get some downtime and it certainly paid off because participation was as good as it had been on other days and brains were only slightly slower than usual. It’s the great thing about having the freedom we have here, teaching only one course and leaving time for work and thinking time. I certainly prefer it as a teaching approach!
Feedback on the quiz and short exam are also positive although there is work to do on making the questions slightly less ambiguous because the terminology of networking often coincides with other uses and there isn’t the same amount of time to get students used to a new reference frame.
After a steamy few days, it seems cooler today and we’re seeing a large amount of blue sky. Here’s what the campus looks like from outside the building I’m teaching in!
