I'm really excited (and nervous) about it because I'll give a talk about my last year GSoC, which I developed a tiled based engine for Okular. I didn't finish my presentation yet but I'll focus on how the tiles are managed inside Okular (the talk will be quite technical).
Of course, I'll publish my presentation here in my blog. But only after (or during) my talk. I just hate spoilers :)
I hope to see you there.
