This offer has now closed, and everyone's books have been sent out. Well done, everyone!
Subscribers should already have started to receive LXF129, and the rest of you will be able to pick up your copy from this Thursday. Inside you'll find a four-page tutorial on how everyone - even someone with only a few weeks of coding experience - can submit patches to the Linux kernel. It might sound crazy, particularly as many people consider the Linux kernel to be Really Hard or out of reach of mere mortals. But I hope that when you've finished the tutorial, you'll feel confident enough to give it a try.
Now, we want to encourage everyone to give it a try, so here's the deal: if you follow our tutorial and submit a patch to the kernel that gets accepted - even if it's only a really, really tiny little change - we'll send you a free book. All you have to do is email me, email@example.com, with your name and address, plus a link to where I can see your patch was accepted. Don't forget, the Linux kernel mailing lists are available online for everyone to read, so a link pointing there is fine. Alternatively, just forward me an email from someone accepting it.
There are some limits: only 1 book per person; the offer is available worldwide; your patch must have been accepted; your patch can be really tiny or simple. Also, we have a limited stock of books, so we're offering this on a first-come, first-served basis.
NB: if you're a subscriber who lives overseas and you haven't received your copy yet, don't forget you can visit our subscriber-only area at www.linuxformat.com/subsarea and download all the PDFs from LXF129 now.
