Django for Beginners and Heroku

I finished up the Django for Beginners book yesterday. The book was pretty well put-together. It had six projects to work through, and I found it to be a pretty useful guide for the simpler parts of Django. I'm going to start working through the next book, Django for Professionals now. I expect I'll be using Heroku again for this book's projects, but I'd like to find a way to host these things on my own server. I may give that a try in the near future. Some of these projects are live now on Heroku. I signed up for Heroku's $5 monthly package since they did away with their free tier last year. It's not too hard getting a project up and running on Heroku, but you do need to have at least a basic understanding of Git and the command-line. I would have preferred hosting these projects on my own server, but unfortunately the book didn't cover that. I'm not posting any links to these Heroku projects yet, mainly because I'm a little concerned about security. The apps are pretty basic and some of them skipped over the security aspects, for simplicity's sake, so I'm going to think about what to do with them to make them more secure.
