DHH is (obviously) David Heinemeier Hansson (the creator of Rails) and RIA (in this context) means Rich Internet Applications. And here is the quote: I think there's always room for new ideas, but I don't think that the whole fuss that's currently going on about RIA, rich Internet applications, is justified.

In the consolidated database, we needed to create single representation that would allow to store both new GUID based identities as well as old int-based keys.

Even with having Wiki as the main documentation repository, not all documentation ends up in a Wiki. Some documentation needs to be managed as part of the source tree - e.g. Readme's, compilation instructions and similar. This information is usually either plain text or in some form of text processor format, mostly Microsoft Word compatible. Both have their selection of problems. Word documents are large, bloated, harder to version controlled and not readable in shell environment (try to cat or tail Word document :-)).
