Hi all, Marks for the quiz are now available on csmarks (https secure.csse.uwa.edu.au run csmarks), and feedback on individual questions should be viewable on Moodle. The average mark for the quiz was 85 , which is excellent. Except for the very las...

Hi all, As mentioned in today's lecture, the 8am Thursday lab sessions have had very low turnout (only one person last week), which means it's difficult to justify running them. I'll therefore be cancelling that lab slot after this week - if you were ...

Hi all, The quiz has now closed, and it looks like the average is fairly high, which is great I take it to mean people have a pretty good understanding of basic concepts. (Or that I made the questions too easy.) As per the rubric rubric , short a...

Hi all, Just a reminder regarding student conduct requirements. I allow a fair bit of flexibility regarding when students sit the online tests they can be started at any convenient time in a 24-hour block. However, students must still comply with th...

Hi all, I won't be holding my usual office hours (4-5pm) today, as I'll be preparing to release the Moodle quiz (worth 5 ) that opens at 5pm. I'll discuss the quiz more in today's lecture, but there are some tips and instructions here quiz if needed...

Can you clarify exactly what it is you don't understand? Otherwise it's difficult for me to know what needs explaining. (In future, it would also be helpful if you gave the exact slide number you're referring to.) However, I do note that you've quoted...

I'd suggest working through (and reviewing) the lecture and lab content, first, and referring to the recommended readings if anything is unclear. There are a few topics which are often poorly understood, though, namely - setuid programs, and - integer ...

There are no incompatibilities between the libvirt disk image and the virtualbox disk image. They contain exactly the same software packages, running on exactly the same Linux kernel, on exactly the same (virtualised) hardware. The hostname (stor...

Glad to hear you got things working. I'll add the username and password details to the lab sheet. Cheers, Arran

WAIT Less stop By following the instructions on https cits3007.github.io labs lab01-utm.html, the .box file they get us to download is from the libvirt provider (you can see this by looking at the URL for the box, https ...

Hi. In the last lecture, it was said that " buf is a local variable, that s in the current stack frame. The other variables in this code are local variables. Those variables are overwritten, then the return address is overwritten, and then the ...

Hi. How necessary are the readings? Hypothetically, if a student could only do one, should they ensure that they understand the lecture and lab content, or should they ensure that they've read all of the readings?

YESSSSS I FINALLY DID IT WOO D D D Less gooo I've been trying this for HOURS But what you said was exactly what I was looking for I didn't realise that the other link that existed in the lab 1 worksheet here (https...

In case people are interested although Java and Python both use exceptions, some more recent languages have moved away from exceptions as an approach to error-handling. (For instance, neither Rust nor Go have exceptions.) A big problem with exception...

Thanks for letting me know. Just to clarify the lab worksheet "Using UTM on M-series Mac laptops" suggests a different process to the one you seem to have used. You've extracted a .vmdk file from your .vagrant.d directory, then used qemu-img to co...

I've tried doing numerous times this but had no success. It's a shame as I have successfully done this extraction before, though it has always been a hit-or-miss. Going into .vagrant.d boxes arranstewart-VAGRANTSLASH-cits3007-ubuntu2004 0.1.4 vir...
