MongoDB in Action is now in print! This means two things:
- You can read a single book about MongoDB that takes you from total beginner to budding master.
- I can start blogging again. It turns out that book writing is much more intense that I’d imagined.
You can purchase and download the book from the publisher right now. ePub and Kindle versions will be available on December 23. If you’d like to read a bit more about the book, check out my MongoDB in Action
Finishing the book feels much like finishing a marathon. There’s deep sense of relief and accomplishment.
Of course, I could not have done it without the support of my family and my amazing colleagues at 10gen.
I’m grateful to all these folks.
The book is dedicated to peace and human dignity. Most technical books aren’t dedicated to ideals, but I
feel that working for peace and the dignity of all human beings is as important as ever and that
expressing that, even in a small way, is worthwhile.
If you end up buying the book, many thanks in advance. I sincerely hope that it proves useful, even enjoyable.

With MongoDB’s aggressive roadmap, new features are constantly being added. Notable in the 1.4 release are the $addToSet update operator, the findAndModify command, and indexes supporting two-dimensional coordinates. Usually the first question from users is whether their driver supports the new features. Happily, the answer is almost always yes; in this post, I explain why that is so.

Want to try MongoDB in your browser? Just deployed this a few days ago:
Anyone who’d like to contribute can fork the code on github.
(Almost forgot to mention that this is indeed inspired by, and is a little homage to, the great _why.)

This is the second in a series of articles on MongoDB’s aggregation functions.
In the first installment,
we looked at count(),
distinct(), and some of the basics of
group(). But group() is rather a beast, so
