I've been using Ruby and Rails and other ancillary technologies for a few weeks now. I've gone through many articles, blogs, tutorials, et al. However, I've rarely found any downloadable "working examples" or "real-world applications". Everything is very basic and it's proven difficult to learn beyond the basics. It could very well be that I'm searching Google with the wrong keywords? In any case, I know sometimes the real gems (pun intended) out there don't always show up in the top of the search results. So I wanted to ask the community for recommendations regarding tutorials, informative sites, and I'd REALLY like to find some apps I can download, run, tweak, etc. Thanks in advance!
