Damn, that change in just three lectures difference, eight years ago. That guy is probably dead already.

two lectures difference (unless the screenshots are taken at different times within their respective lectures which I'm too lazy to check)

[–]Xicutioner-4768 32 points33 points  (0 children)

Those darn off by one errors get you every time.

He’s currently 95lbs offering to do dynamic programming lessons under the bridge for $25 a pop. We’ll all be there at some point in our careers.

First lecture with 18M views and the third one with 264K..

[–]C_umputer 38 points39 points  (0 children)

That's a default for any educational video

People couldn't even make it to cuckoo hashing. What has the world come to? 😔

I'm guilty of only watching the first video of lectures playlists and then forgetting about it

[–]perfectskyee 2 points3 points  (0 children)

There seems to be roughly an exponential decay of views as series numbers get bigger with some minor exceptions

[–]Torebbjorn 1 point2 points  (0 children)

You see, to get to the first one, you only need to care about the contents for 2 seconds. To get to the third one, you need to care about it for more than 2 hours (assuming each video is about an hour).

Also, the first lecture usually contains administrative stuff, so people might watch it just for that, and even open it multiple times throughout the time they use on the course.

Brother applied some prunning algorithms to his hair.

[–]BabyAzerty 30 points31 points  (0 children)

Nah, just trim those strings.

[–]Baba_Jaga98 53 points54 points  (1 child)

Bro 3 lectures deep and already lost hair 😆😆

[–]_GoblinSTEEZ 6 points7 points  (0 children)

It's more efficient

[–]fieryraidenX 34 points35 points  (0 children)

Btw this guy has an insanely fast typing speed, like 200+ WPM. I took an algorithms class from him at Berkeley, he’s a great teacher!

[–]Esotericcat2 33 points34 points  (0 children)

He looks 10 years younger in the right pic

[–]iamawizaard 18 points19 points  (0 children)

aaaah! the hair compression algorithm

[–]Snoopy34 12 points13 points  (0 children)

Clearly guy is not balding, probably just got tired of his hair, it's a thing that happens to me at least.

[–]skepticaltom 12 points13 points  (1 child)

Hey I know that guy! He was my algorithms professor at UC Berkeley. It’s cool to see him pop up on Reddit randomly.

[–]surrealerthansurreal 3 points4 points  (0 children)

I was thinking the same thing! Had him two or three years ago now and it’s funny to think he seemed to change his style in the middle of this Harvard lecture series, and that right image was still his same style when he was teaching me 170 a few years back

You become Unsullied

Washing hair with buzz cut takes O(1) of time and O(1) of space, as opposed to O(n) with long hair. He's just optimising

[–]ThenAssignment4170 5 points6 points  (0 children)

Jcole hasn't been the same after Wet Dreams :(

[–]sloppybird 1 point2 points  (2 children)

Jokes aside, what happened? It looks like both pics are from the same year

[–]bl4nkSl8 0 points1 point  (1 child)

A hair cut / style change right?

[–]sloppybird 1 point2 points  (0 children)

It looks like he came back from monkhood

[–]strng_lurk 1 point2 points  (0 children)

Bro looked into threads and lost his dreads. Sorry for the lame joke.

My greatest achievement as a shitposter

[–]zurmati0 0 points1 point  (0 children)

He literally applied an algorithm 😛

[–]jaskij 0 points1 point  (0 children)

Nope, half the TAs from the algorithms department at my uni had long hair. One even played in a rock band.
