COMP6021 Week 05 Preview

Next week we will begin our look at compression algorithms.

I expect we will see

• Run Length Encoding
• Relative Coding
• Variable Length Codes
• Huffman Coding
• Lempel-Ziv-Welch Coding

but that might be asking a lot for one week

COMP6021 Online lesson on Compression

Students should watch this video in advance of the next class.

There's a downloadable higher quality version here.

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.

COMP6023 DWEB1 Class 15 & 16

I met with each student and discussed any language issues in the blog posts that needed to be addressed.

Class Recordings will Stop Soon

Making recordings of classes is becoming increasingly difficult and time consuming with the hardware I have. My machine is so slow that I'm not able to record to classes back to back anymore. My ability to properly record sound is starting to fail.

It's a pity that my experiments in putting classes online should end for money reasons. A lot of potential value is added to my teaching by making classes available online. It's hard to put a precise money value on it. But given how much I cost the taxpayers in a year, even a 1% increase in added value would justify the price of a new laptop every year.

The saddest part though is that it makes me feel like my efforts are not valued.

I'll continue to muddle through. But students should expect fewer classes to be available online from now on. Recordings from previous years will still be available. So they may be useful in filling in any gaps.

COMP6021 Classes 14 & 15

Today's classes are canceled.

I'm not feeling well so I'm going home.

COMP6023 DCOM1b Classes 15 & 16

I met with each student and discussed any language issues in the blog posts that needed to be addressed. Students are free to make corrections until the posts are actually assessed. (That will probably be at the end of Week 05)

COMP6023 ITM1 Class 15 & 16

Photoshop is working in C134x now, so students worked on the JPEG images for Assessment 2.

I met with each student and discussed any language issues in the blog posts that needed to be addressed. Students are free to make corrections until the posts are actually assessed. (That will probably be at the end of Week 05)

COMP6023 DNET1 Classes 15 & 16

Students worked on their blogs. Some took the NewsU course today. 

I met with each student and identified some issues with grammar and spelling that needed to be addressed. 

COMP6023 DNET1/COM1c Class 14

I asked student to discuss in group what 5 or 6 categories privacy concerns might fall into.

It didn't really go well.

COMP6021 Class 13

the one with the 日本語

[sound recording failed half way though. so video not posted]

We concluded our look at representing text. I explained how writing works in Japanese and we looked very briefly at HTML.

Aside:
Students who found this interesting might enjoy this radio programme on the story of written Cherokee.

COMP6023 DWEB1/ITM1 Class 14

I asked students to work on groups on figuring out headings of themes for privacy concerns.

I felt like students didn't really get into it. Perhaps I didn't make it clear what I was asking.

We put come ideas on the whiteboard.

COMP6023 DWEB1/ITM1 Class 13

We looked some more at how search engines work.

I asked students to consider and discuss what Google might now about them.

We looked at advanced searches using Google's syntax

COMP6023 DCOM1 Class 13

We looked a bit more at how search engines work.

I asked students to discuss for a few minutes the kinds of things Google might know about them. But of course many of those things are not things that one shares in class.

We looked at advanced searches using Google's syntax.

COMP6023 DNET1/COM1c Class 13

We continued our look at how search engines index sites.

I asked students to discuss for a few minutes the kinds of things Google might know about them. But of course many of those things are not things that one shares in class.

We looked at advanced searches using Google's syntax.

[No recording of today's class]

COMP6023 Week 03 Summary

The plan to do an olde school FTP session to a UNIX machine didn't work. The Windows security systems thought we were trying to bypass the local firewalls. We might try again another time.

Students got the images they needed for Assignment 2. Some were able to make a start on gather the data using Photoshop. Others had problems with Photoshop. Those issues should be resolved in those labs by next week.

Students should write a movie review for the blog this week.

Some students have completed the NewsU course. I have marked those students with a 1 on the blog list. I'm aware that the links to the student blogs are acting strange. I haven't been able figure out what's up with the PDF. In the source document they are fine.

The most popular essay choices are booked up now. Students shouldn't take too long to decide. I may have to consider a deadline soon to move that along.
