I started the second day quite late. There were a few sessions I wanted to see there but not enough to get out of bed early enough. After lunch I saw parts of David Pollaks talk on Lift. Lift is definitely impressive – you can achieve very powerful things very quickly with it.

After that, I saw Rich Hickey talk about Persistent Data Structures. This was without doubt the best presentation at QCon this year. Rich spent lots of time talking about identity, state and value. It was very good – you should go to http://qconlondon.com/london-2009/schedule/thursday.jsp and take a look at the slides for it. It is pretty deep stuff. I heard many other people share my opinion of the quality of this talk. QCon and JAOO could do much worse than getting Rich back for the next time.

Overall, I spent most of the Thursday having chats with interesting people instead of watching presentations. It was a good day in many ways, especially due to Rich’s talk.
