Lecture 7: Side Effects - Richard Buckland UNSW 2008

[@DIABLOVT12]

Man, I love Richard. This is what teaching should be like. We need more Richards! :p :)

@UNSWelearning Oh no! Lecture 7 was replaced by a stub video! I was so excited to share Professor's impersonation of the computer(see comment below from a year ago). He does such a great job keeping things lively. This was honestly one of my favorite videos of all time. Please reupload if you can. Thanks!

you can download the full one.

@ download from where? Thanks.

[@YoeyYutch]

​@ This video is only three minutes long. The hour-long lecture video was removed and this video was put in its place. In order to download the original video I would need that url.... unless I'm missing something. No big deal. I just like his little spiel about returning zero from main. It's in the transcript...

32:47 if it's not there what's your operating 32:49 system gonna do what's that 32:52 whatever it's allowed to do whatever 32:54 wants I mean maybe there's a bit of 32:56 rubbish stored there there's it's 32:58 expecting this function to return a 33:00 number it's set aside a little spot 33:01 inside it's much precious area and 33:03 thinking I think the function finishes 33:05 they'll put a number there and that's 33:07 your whole program when it finishes is 33:09 summarized everything else your program 33:11 does is a side-effect when your program 33:13 finishes the only thing that summarizes 33:15 the behavior of the program is the 33:16 number it returns everything else is a 33:18 side-effect so the operating system it 33:20 doesn't know what you're doing it just 33:21 knows at the end it gonna give me a 33:22 number when they finished you don't give 33:26 it the number your party says he's 33:28 finished I'm gonna look in the precious 33:30 spot and see what number he returned oh 33:32 nine million three hundred and twenty 33:34 six thousand eight hundred and seventeen 33:36 - because that's cuz that's a random bit 33:39 of rubbish it was sitting in X it hasn't 33:41 been initialized yet oh that means he 33:44 wants me to explode

It's funnier when he says it :)

[@YoeyYutch]

32:57 He's so funny when he impersonates computers. I like how excited the computer is to get its int value returned.

Does anyone know the answer to the question regarding why the 24th instruction isn't named "Instruction #16"?

Video is not working, stops after minute 3

[@CerberusDawg]

What happened to this video? It was about 1 hour long and I watched it for about 10 minutes when I had to go off and do other things. Now it's suddenly only 3 minutes long and I can't watch the rest?

[@CerberusDawg]

Ah, it’s back and it seems to be complete now at around 39 minutes. From other comments it looks like this happened before. Weird. Anyway, great lecture as always. I am learning a lot!
