Thanks to everyone who came to my presentations during DevTeach. I’m going to try something different than zip files for distributing code samples. I’ve set up a public Subversion repository on Google Code here. If you’ve got a Subversion client (such as TortoiseSVN) installed, you can point it to:

The slidedecks are available in the repository, but I’ll provide them here for those that don’t want to go spelunking through the repository…

The Persistence Ignorant Domain Model – PI and, more generally, anti-corruption layers between your code and frameworks, are incredibly important in creating maintainable software. I’ll definitely be talking about these issues in the future. Slidedeck can be found here. Demos can be found in the SVN repository.

Agile Panel with David Laribee and Friends – I qualified in the “Friends” category. The discussion panel was a lot of fun and David did a great job moving the topics along. No slides or demos to see here. Move it along…

Enterprise Version Control – Bil Simser and I did a presentation on best practices in version control. We discussed both Subversion and TFS, though all of our demos were done with Subversion. (The reason… Setup time for a Subversion server – 5 minutes. Setup time for TFS – longer than we cared to take. Yes, both Bil and I have set up TFS before. It’s just a lot more complex than Subversion, though it offers more out of the box.) Slidedeck can be found here (SVN) or here.

Queuing and Caching to Scalability – Other than the technical difficulties in getting my laptop to talk to the projector, I had a fun time with this presentation. (Thanks to the attendee who lent me his laptop so I wasn’t just talking in front of a blank backdrop.) After spending so much time making sure the demos ran flawlessly, I was disappointed that I didn’t get to show them. Slidedeck can be found here. Demos can be found in the SVN repository. The code should be fairly self-explanatory. To run the demos, you need to install MSMQ and create two private queues called messageboardqueue and newbabblesqueue. If you have any questions or problems with the demos, please email me. I’ll try to put together a screencast in the next few weeks for those who are interested, but don’t want to go to the trouble of installing MSMQ.

I appreciate all the feedback I received, both the positive and negative. As a speaker, the best way to improve one’s craft is to critically examine the past presentations by accepting attendee feedback. I think about what went well (and should continue doing) as well as what didn’t go so well and how to improve. Very much like an iteration retrospective in agile development. So keep the feedback coming!
