Just like they did with No Starch Press, Humble Bundle has just offerred a new O'Reilly bundle with (up to) 16 *NIX ebooks for as little as $15 US$. Not bad. None are their newest titles, but there's still a lot of good stuff in there. And we all know that with *NIX most things don't go obsolete.
If my math is on target, you have until Dec 7-ish to act on this.
As with the NSP bundle, MUUG will be purchasing one bundle for DP giveaways. (And I'll be buying a set for myself too, though like many of you I already have around half of them on paper!)
Thanks to Adam for originally spotting this.
