I'm still not great at selfies... Here you get two for the price of one tho.

The second edition is officially out!

Thanks to everyone involved!

If you've been reading the free online edition and feel like showing your support, then now's the time! There's not a huge amount in it for me financially (I get about a dollar off every sale) but it does add up, and O'Reilly also deserve your support, they've been great.

Reviews, please!

More importantly, I really need some reviews for the book, on Amazon and elsewhere. They make a real difference to sales, and they really help other people to make the decision over whether they will find the book useful. So if you've enjoyed the book at all, do write a review for me online. That would be very, very much appreciated.

Thanks once again, dear readers, for your kind words and encouragement throughout the process. I couldn't do it without you.
