Each year I try to attend at least one developer conference. Earlier OOPSLA was a given but it lost its appeal quite a few years back and now it is not even called OOPSLA anymore. As a die hard Smalltalker I instead attended the ESUG conference in Brest 2009 and it was easily the most rewarding conference I ever have attended! Missed last year in Barcelona but this year I am going to Edinburgh for a week of Smalltalking.
I am not presenting anything but I hope I will get my HP Touchpad from Amazon before it starts so that I can demonstrate a WebOS app running on it written in Jtalk.
If you are going too, see you there!
