COMP6023 Review of Week 04 / Preview of Week 05
Review
This was a slow week I felt. We didn't do much technically, although maybe the conversations about privacy were worthwhile.Hopefully those students who need to work on their writing skills are aware of that now.
Students should complete the NewsU online course and post some thoughts on that for the blog this week. Quite a number of students have yet to complete the course. Failure to do so by Sunday evening will very likely cost students some marks. We will return to some of the issues covered by the NewsU course later in the module.
Preview
Next week we will begin our look at Search Engine Optimization(SEO) in earnest.I won't be able to make the DNET1/COM1c class on Tuesday at 1400 as I have a meeting I must go to.
For next week's blog post students must write a book review. (And not the book of the movie reviewed last week)
COMP6023 DCOM1 Class 14
I asked students to consider the privacy issues they had identified in the past, and see if they could classify and group them into 5 or 6 categories.
This was probably the most interesting class I've given this academic year so far. And allI had was a marker. I wonder is there something to be said for going commando and leaving the laptop in my office.

COMP6021 Class 16 Tutorial
This was a tutorial class. In general, for tutorials students must bring the questions. However I gave the students some UTF-8 coding/decoding exercises. I think everyone has got it now.
Attendance at tutorials will be optional. But attendance is recommended.
