55:45 That hospital should sue microshit and beyond that if the idiots in that hospital had any brains they wouldnt be using microshit for anything critical *at all*.

[ThunderAppeal]

I have never seen a segfault, a bugger overlfow or anything of this nature since I've been running Slackware GNU/Linux.

[BestTypoEver]

Stack frames actually start at 39:00

".. then you produced a stack overflow vulnerability and we write you a recommendation letter to Microsoft." ROFL

Really great lectures, it is really good for people learning the little problems of programming and how to begin solving a problem! Thumbs up.

[swaip1]

wonderful lectures, had problems doing sudoku assignment in java, and this helped me a lot

[darijo203]

Someone should give an update to this professor. Stack overflow attacks are "not" an issue any longer, ever since Intel introduced NX feature.

[unswelearning]

hi darijo, thanks for your comment. i think we'd all love it if a simple change at the chip level could remove the problem of buffer overflows and perhaps even mem vulns in general! With the low level memory flexibility C give us comes great responsibility, sadly not fully appreciated by many c programmers. (if you remain unconvinced google "stack overflow advisory 2009"...) keep up the sceptical thinking tho, it is good to see.

I'd like to say something about the taking notes to the exam idea: in our modern way, this is by far the most logical thing to do. Humanity has amassed tons and tons and tons (and tons and tons) of data now... it's impossible to remember even a reasonable fraction of it (unless you're Kim Peek, at which point you can't do much with the data but recall it), BUT we CAN remember where to find all the information. It's like code snips for a test ^.^

void TakeNotesToExam(){

knowledge++;

return knowledge;

}

[blackcastlesoft]

heh does that mean the knowledge is void? or that it's void of knowledge?

[doubleem12]

I reeeeeeeeeeeeealy hope that was intentional.

[amino0o]

it was

[0121ryanh117]

error : Void not ignored as it ought to be.

[skinnycat59]

lecture 22 is flagged as private :-(

I missed the sudoku program :-(

[Truthiness231]

Google: c source sudoku. It's been done a million times already.

When in doubt, Google it =P (and thus making them just a bit more powerful each time... but... yeah...)

[andrewredss]

Lecture 22 is now public again

[skinnycat59]

Yay! :-) thanks for letting me know

[witchhammercult]

Thank you, Richard and UNSW! :)

[theLichKing1]

is the wiki he talked about in the beginning available to the public? or just UNSW students?

[extension1337]

finishing up with sudoku program at 8:21

[cymonsgames]

Does any one of the link to the sumo robot video he was talking about and does anyone know the link to the forum he mentioned?

I love these videos.

[davidalfredjames]

Cheats!

[CptRick999]

Stacks are French?^^

[TijuSujiT]

At 31:38, how does 9x9x9 becomes 9^81????

9x9x9==9^3== 729

[sspoke]

yup 9 to power of 3 is 729

and by 9 to power of 81 i think he ment by max elements in array and 9 per box which means that much combations in the whole game.. like playing a lottery..

[themarman]

if you look at how he wrote the expression he went like this

9x9x9...9^81

because the are 81 cells in a soduko grid and each cell can have 9 possible values, thus,

9^81
