I have taken the decision to delete my presentations archive page on this blog. The reason is very prosaic: my presentation slide decks do not really work as handouts and they are simply an aide for the delivery. They are intentionally designed as such and would not work as well otherwise.
Without delivery the presentations do not make much sense and hinder more than they help understanding. It's like reading a book where most of the paragraphs are missing.
In case you were looking for a particular presentation I have done in the past, feel free to drop me a line.
