This was my favorite lecture so far. I loved learning about the mechanics of pixels and such. Thank you so much for uploading this course!

I just can't believe someone said the bliss image was from windows vista.
I can't.

He says the word "arcane" at least once every lecture.

At 41:00 does *(t + i) mean "the value at address of t plus i bytes"? If so, wouldn't it be better do it like so *(t + i * sizeof(char)) to make sure that the right byte offset is added to the pointer, if I don't remember size of a particular data type, for example?

Why, at 48:17, did he have to use "swap(&x, &y)" rather than "swap(*x, *y)"? How does the use of the * differ from that of &?

Lowest attendance, highest views... ;)

[daveridarelli]

Intro should finish with good ole' Super Troopers

[dhsaad]

I have one question" Why do we multiply when converting Ev to J alone"I hope someone will answer me quickly😢😢

[Akshay-cjhq]

im confused about addresses. So for example, if you say x=5, why does it change x to 5, and not just the address of x?

[abdelrahmangamalmahdy]

why does he say 42 "the meaning of life" ?!! where does it come from ?! was this a movie or what ???

[sighko]

There's this tiny high freq feed. My ears are annoyed.

[aalhalimsd]

well now it begins to be horribly complex 😣

[hasanalattar]

try this
*(s+i) = *(i+s)
hence,
s[i] = i[s]
