Update [2011-08-23 18:49 UTC]: The Rough Cut of Clojure Programming has been updated significantly since this post originally went live. Go check it out. :-)
Some time ago, I announced that I was coauthoring a book on Clojure for O'Reilly (see original announcement). I'm very happy to report that an early and incomplete version of Clojure Programming is now available in Rough Cuts.
Rough Cuts is O'Reilly's early-access program, similar to Manning's MEAP. By purchasing it now, you will be able to read the ebook via Safari as it progresses through its final stages, and leave feedback that we will take into account through that process. Please make use of the comment/feedback facility on the book's Safari page; we are eager to hear what you have to say about the book — though personally, I vacillate between hoping you'll be gentle and hoping you'll be brutal.
What's in the first Rough Cut is actually the state of the book from about two months ago. I dropped the ball on giving the final word to our editor to go ahead with the release, so I'm afraid you're all getting this much later than you could (and should) have. On the upside, there's a lot of content queued up to be added to the Rough Cut, so you'll be seeing new stuff stream in very rapidly from here on out.
I do want to apologize about (inadvertently) maintaining radio silence about the book since my original announcement. Writing the book has ended up overlapping with a very busy time in my life, and I needed to recruit new coauthors mid-stream to boot. Dave had some killer opportunities that he simply couldn't turn down; his departure was unfortunate, but it gave me the great opportunity to work with two very well-known figures in the Clojure community:
I'm biased of course, but the book is shaping up to be what I think will be a great introduction to Clojure — especially for those coming from Java, Ruby, and Python — and simply none of it would have been possible if it were not for Brian and Christophe. Thanks, guys! :-D
P.S. I just want to take a moment to let it settle in that, yes, O'Reilly is publishing a Lisp book, despite their explicitly discouraging Lisp topics in their book proposal guidelines. (Sorry guys, a single friendly needling is warranted. ;-)) I know it's not an old concept (they accepted our proposal, after all, and then there was the sadly ill-fated Lisp: Out of the Box), but now the bits are flowing, orders are being taken, and it can't get much more official. Happy days indeed.
