This was my CodeRage 4 presentation back in late 2009. It's very introductory stuff and Pascal only. It's based around a couple of chapters in Marco Cantu's book Essential Pascal (produced with permission). The presentation is about 35 minutes long. You can watch YouTube.
This book will make you a faster Delphi developer, it doesn't matter if you are just starting out, or have been using Delphi since version 1, you will find all sorts of tips, tricks and hacks to boost your productivity.
