Also: the course ENGG1000, wiki textbook (idea from hong kong). Predicates, comparing with TRUE. Stack overflow.

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

  • 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.

  • ".. 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.
