To those people complaining that this is not a great presentation - I would rather listen to somebody who really knows what he's talking about, and is enthusiastic about it, than listen to somebody who is a "professional presenter". I''m no fan of Facebook, but we should all be grateful when we get to listen to someone who is an expert in their field giving us the benefit of their experience.

Paying my respects to Zucc here, he does a good job at explaining memcache.

Video from 2008, uploaded in 2013, watching in 2020. UKposts algorithm, unresolved mystery ...

This talk really underscores the importance of optimization. I like how they got into the guts of the servers (such as network drivers) in order to make more efficient use of memory and processor use. Also, the switch from TCP to UDP made a lot of sense.

Nice work on the interplay of coding/design decisions and real expenses at long term and large scales

I like how Mark explained his lecture. So easy to understand. I've had problems with other lectureres, they just didn't explain it well. But he did very well.

Holy. Just having the string length instead of doing `string.length` saved so much money. It's crazy to think at the scale that Facebook has, having one duplicate line could cost millions of dollars in time over it's lifetime.

The video cuts off right when it gets to the really good stuff!

This is an interesting video. Mark explains this well, without being too technical.

I think it's awesome that andrew WK party hard breaks in at 14:47

Anyone have a link to the rest of the lecture?

Very good presentation

Is there kernel patch for making slab allocation from power of 2 to 1.3 ?

8:07 are these the right slides??? :P

Good presentation that I can keep watching

Do they still use memcached? What does their current stack look like?

11:16 and that brought about the largest ddos attack years later for github

where is the rest?

Did he write memcahce or did he just deploy it on FB? because thats a big difference

Superb sir

Many folk seem to reckon powers of 2 are wasteful. Java's ArrayList grows by powers of 1.5. SQL Server grows database files by powers of 1.1. These are general purpose algorithms. In your case powers of 2 might be the right thing. Understand your data and test accordingly!

awesome in depth understanding

Zucc is so much more personable when he isn't trying to be personable. A nerd in their element is so endearing

Daddy Zuck talking about memcache - omgz

watching this 8 years later.

Mark Zuckerberg is great at explaining complex things so simply.

World really missed an brilliant engineer

Who stole the rest of the video? ;-)

14:45 ...?

when is last time Z presented a tech talk?

it is not finished

Good morning sir!

Thanks yt algorithm

so basically he made redis for facebook?

why facebook didnt switched to some other technology?

and it saved millions of dollars!

Am I the only one that keeps scrolling up?

Hey great vid....I need some help here.The 'Gaming' tab has replaced my 'Friends' tab on my Facebook account... Is there a way to reverse this? I'm on a desktop PC ...Please note, You wont see it on your account once it is functioning properly ... But on my account on the area at the top of the page where there is usually : Home, Friends, Watch, Marketplace ,Groups etc, I am seeing 'Gaming' instead of 'Friends'...But not on all the Facebook accounts (For example:- if I log into my wife's account its fine and as it should be)...I also noticed, my new friend request has severely throttled down as a result; my account is set so everyone can send me a request...About two weeks ago it reverted just for a moment an the friend request bumped back up...but sadly was short lived...tried several attempts to contact Facebook and the Community for help...but nothing so far . Your help is appreciated.

Iterate really fast, build really bad UI / UX... woot..

2 -> 1.3

Just google everyone's name in this video...

facebook, why memcahe and not redis?

just love zuck❤

It will always be a rip off of myspace

Just say is not good

This is the most lame presentation I have recently watched
