Time for another update on my DSL book's progress, since I've not been writing anything else recently.

I had my first round of technical review late in 2009 and have been incorporating comments into the current drafts. Progress on this has gone well, in large part because travel is light this time of the year. I'm also integrating my book production process into that of Pearson's.

The next visible targets are a second round of technical review and the launching of a roughcut. We're hoping to get these going in the next couple of months. The roughcut will also allow people other than official reviewers the chance to throw rocks at the text.

After that the material will be gradually readied for production. We're going to use a much more incremental process than I've used before, which will be both good and interesting. My sense at the moment that we'll see a physical book on bookshelves by the final quarter of 2010. It's currently looking at around 500 pages total in a DuplexBook split 150/350

The material currently on my web-site was last updated in June. While I've done quite a lot of detailed work on the book since, the broad structure is pretty similar, so the website gives a reasonably good picture of the scope of content.
