My talk for Smalltalk Solutions was a tutorial called Using Glorp. In contrast to some of the previous talks I've done, this one concentrates more on how to use Glorp and less on how it works internally or the rationale for design decisions. It was tricky, as you might expect from something with hands-on exercises that requires everyone to have a database. I was hoping we might be able to use wireless access and give people access to postgresql running on my laptop, but that didn't seem to work out.
In the end, enough people were able to get going using Access on the Windows machines. That had a few entertaining aspects. I had to hand-wave a bit - "Let us assume that a real database would not cause an error if you did a read before starting the transaction, and just do it afterwards".
I also had to go fairly quickly through some of the later material. I wasn't sure how fast things would move, so I had some extras, and also people asked a lot of fairly advanced questions in some of the early sections. So the ordering was interesting, but I was pretty happy with the amount we got covered.
