We looked at user input validation and checksums.
We looed at code for mobile phone number validation and the Luhn credit card algorithm.
In the next lab class students will start coding the Luhn algorithm. I advised students against look up solutions online. It's best to start with a clean slate and a blank sheet of paper.

COMP8035 Class 02
I met with each student and talked through some ideas.
All the students who were there seem to be on top of things. But the main output for this module is the research Report at the end. So all efforts should be considered as stepping stones on the way to that.

COMP6021 Class 02.4 - Zombies, Semaphore & ASCII
We looked at some solutions for the traffic light zombie code and considered some advantages and disadvantages.
We looked at Braille, Semaphore, ASCII, DOS Code Pages, and extended-ASCII
Next up: Unicode
COMP6021 Class 02.3 - Negative Numbers
We played Binary Bingo, but the winner wasn't aware that he had won.
We looked at One's Complement and Two's Complement representations of integers. I explained why they were better that sign & magnitude representations. We looked at using offset binary for awkward situations. I briefly mentioned IEEE Floating Point, but we won't be going into that.
We began our look at representing text. I outlined the problems facing Outpost 19 after an attack by the zombie hoard, and asked students to devise an efficient communication system for the traffic lights.
SOFT6008 Class 02.2
I asked students to continue working on the phone cost calculator.
And then the slot machine exercise.
These images might be useful

COMP6021 Binary & Hex Tutorial
This video is a great refresher if you've forgotten how binary and hex work.
COMP6021 Class 02.2 - The Sock on the Door
This was, in fact, our first class.
I introduced the module and talked a little bit about the assessment.
We look at how bits can be used to represent different numbers of things or state, depending on how many bits there are.
We looked at how bits can be used to represent positive integers, and represent integers that may be negative (sign & magnitude)
Slides:
Next up: two's compliment
SOFT6008 Class 02.1
We took our first look at the Document Object Model (DOM).
We looked at how to do rollovers. I showed students the coins toss game working and asked them to work in pairs and speculate what the code might look like.
Next up students will be expected to extend the coin game and turn it into a slot machine.

SOFT7008 Class 02.1
The projector wasn't working so we couldn't have a lecture.
I gave students a short programming skills assessment. Some student struggled with that. Students who are not comfortable with programming might want to consider another option.

SOFT6002 HCI Week 01
I introduced myself and talked a little bit about he assessment for the module. The modules descriptor is here.
I talked about the importance of HCI and we looked at five of Neilsen's heurstics.
Slides:
HCI-W01-L1
HCI-W01-L2 Starting Heuristics
I sent the slides by e-mail and a link to the module website maintained by Paul Rothwell.

SOFT6008 Class 01.4
We looked at prompts and dialog boxes, and loops.
I asked students to implement a change visualizer.
A few students finished quickly so they took a look at the Phone Cost calculator and tried to figure out how the absence of PasreInt was making the program fail in certain circumstances.

COMP8035 Class 01.3
I asked students to find an interesting article from the list of journals listed other there --->
and to write 400 words on the topic. That's for Week 4.
I want students to become familiar with ACM and IEEE journals. They are all available via
http://library.cit.ie

SOFT6008 Class 01.3
I asked students to make a craps shooting game using images of dice and Math.random()
Some students struggled with the escaping of the ", but otherwise it went well.
Good job guys

SOFT6008 Class 01.2
I asked students to take the examples we did in the last class and mess around with them, and tweak them, in order to understand how they work.
SOFT6008 Book Recommendations
I recommend students buy one of these books.

SOFT7008 Class 01.2
There were very few students in class. So rather than repeat everything next time, I decided I would post a video on how to set up PHP so that everyone can be up to speed for next week.
As of today there is no room timetabled for tomorrow's class. If it is there by tomorrow we will meet up. Otherwise I will see you again next week.
SOFT6008 Class 01.1
I spoke a bit a but JavaScrip and where it runs.
I outlined that the first 40% of the CA will be an in class written exam (date later) and the reaming 60% is a coding assignment.
We looked at two examples of dynamically building up a page using document.write ()
Time based greeting and New Orleans Random Image
There were quite a few very good questions. That makes me happy.
Slides: js01d.pdf
I stressed the importance of coming to class and working through the exercises. That's the best way to learn to program in JavaScript. Googling for solutions is less likely to result in success.

COMP8035 Class 01.1 Introductions
The module descriptor for this module is here
I gave a handout that outlined very briefly what the assessment for this module is going to look like. I gave a handout from wired.com about Predictions for 2015. We looked at those to see if there were any ideas worth looking in to some more.
By the end of Week 02 student will post to their blogs a list of 5 relevant twitter feeds worth following for this module and a brief description of what to expect from each feed.
I asked students sign-up to use Delicious.com and to tag pages relevant to this module with CIT-COMP8035
I will maintain a page of resources for this module and add to it from time to time.
I spent the bulk of the class discussing what the Written Report will look like.

SOFT7008 PHP Class 01.1
I introduced myself, but I had actually met most students before.
Only five students turned up and there wasn't a computer, so we didn't do a whole lot.
I emailed everyone in ITS2 and ITM2 about the module.

I emailed everyone in ITS2 and ITM2 about the module.
This is your recommended Free Choice module for this semester. This is a programming module.
You are free to choose a different free choice module, but it is very unlikely that you will find one that fits in with your timetable. If you are choosing a different one you should do so quickly.
The CRN for this module is in the e-mail I sent. Please register for it online.
The next class is Tuesday at 1400 in C169. Please attend.
This modules requires a web server and PHP server. If you typically bring your laptop to college please bring it on Tuesday. Alternatively please bring a USB memory stick.
