If you’re like most developers, you can get through most of your projects with just lists and maps. Then every once in a while you read a blog post about a mind-blowing problems that can only be solved efficiently because of a data structure you’ve never heard of, and you wonder where long years of computer science education really got you. Or better yet, maybe you never

The world is full of interesting data structures like Merkel Trees, Bloom Filters, k-d Trees, Ropes, Tries, and just plain old heaps and graphs. Come to this talk for a fun walk through the composition, purpose, and implementation of a few of the data structures you think you need to know—and might actually be able to use!

Unsure if it got added. So I’ll double post

Mr berlund has a very pleasing style, similar to Edd Dumbills, both add a certain sense of style to the conference.

He covers data structures competently within the time limits, I learned about a new one so it was useful for me.
