Great recap of the 'Datastructures' course I followed at the Utrecht University in my BSc phase :)
SPL Data Structures and their Complexity
Jurriën Stutterheim (17.Sep.2011 at 13:30)
Talk at PFCongres 2011 (English - US)
PHP 5.3 gained several new SPL datastructures. Since it is important to know when to use which data structure, we will look at the way they work and their algorithmic complexity. An introduction to complexity analysis is given to familiarize the audience with the big-Oh notation and the concepts of space and time complexity. We will then continue with discussing several of the SPL data structures.

Great and interesting talk. Very educational and very good explaination of big-O notation.

Great talk. This kind of talks make me attend this conferences.

The content of this talk is way over my head, but now I understand at least that I have used heaps wrong

Got a great insight about the Spl dayastructures. I'm sure to use them soon.

Great talk, quite hard to follow the in depth math complexity and the abstract explanation. Did a good job keeping the crowd entertained

excellent talk, especially enjoyed the o, omega and theta parts.

Having a fresh memory of my data structures uni course the talk felt like a lecture. A big difference is that you explained it way better than my docent ever could and since university focused on Java it was very interesting to see the comparison to php. Well done :)

A solid talk focussing not on basic tips&tricks; but on the concepts and reasoning behind the uaage of these particular data structures. Very well done indeed!

You gave me a new inspiration. I never thought before about analyze PHP Structures this mathematical way. May be a new activity for me. Excellent hold session at all.

Pretty good speaker, but try to avoid "ehh".

His satin American English delivered a hugely interesting story. Kudo’s for making a difficult subject understandable in less than half an hour ánd making a point with it in PHP. I still think quality assurance is even more important for PHP, but this topic definitely deserves more attention. The talk itself was quite relaxed and Jurriën expertly answered the few questions that came his way.

Ten years have gone by since I heard about big-Oh, big-Omega and big-Theta. Because I didn't had a real use case for them I apparently forgot all about them, and as the slides evolved my memory came back (thank God).
I really enjoyed the presentation because it gave me a deeper insight in why you should use the different SPL structures. Some real use cases would have been welcome in when to use each. Jurriën basically said "reason with your logic and try to figure it out."
That people with no Math background found it hard(er) to follow is normal, the talk was labeled: "advanced".
About the speaker, well he was very clear to understand and did a great job promoting the usage of these SPL datastructures, which thx to this talk I am going to re-visit.

Very good talk and very easy to follow speaker.
The math was way over my head and I think most of the attendees. The presentation might do better with a little less theoretical information.
Also a bit more information how to use the different structures in PHP in reality would be nice. What structure to use in what situation for instance?

10 minutes in and quite a complex talk already. Too much math background for me. Good and native speaker though ;)
