It wasn’t exactly *hard*, but the lack of concise documentation meant I had to mess around for quite a while before I managed to get the UoA package running. So here’s the complete list of commands to execute:

$ apt-get install R-base
$ R
> install.packages(“s20x”)
> library(“s20x”)

edit:
I forgot that command line programs can’t display graphics, so all the plots and stuff won’t show up. So back to Windows install… >.>

Still missing the sticker on the bottom, gonna do it tomorrow.

The probability of drawing the same name 3 times from the box is 0.0008. This event happened.

Question: Do you think the names in the box were well stirred?

My answer: I think the boxed was well mixed, but the drawer was cheating.

Result: -10

I’ve finished coding my SE251 assignment (chess). I had the code up and running since before the break started but recently I’ve been reading a certain book on software design and decided to change a certain abstract base class to an interface, like I said in my last uni post.

Today I looked back at my other code and realised a lot of it wasn’t as reusable as I would’ve liked. For example, the number 8 were hardcoded into many places that should have been using variables instead. So began a quest for refactoring. Now, my Board class can be completely reused for any other board game without any change of code (except for the package declaration), as long as the Piece class for that game satisfy a certain condition which I won’t mention due to any prying SE251 students’ eyes

I’m pretty happy with the resulting code.

CS201 test results were put up on Cecil today. I got A+, and I’m really happy, as you can tell from this smiley =D
