As you probably know, I'm a fan of Humble Bundle. To date, I've made something like 6 posts about the various bundles which I've thought were relevant to this community, and will often drop hints about them anywhere that I see fit.
And, frankly, I have no desire to stop doing this, as I think they're great value for money, and can lead to some amazing things. But, I'm beginning to realise that I probably don't really need to start a new thread for each new bundle of relevance - instead, I can simply create one thread, and each time there's a new bundle, just post to that thread.
Welcome to that thread.
I'm kicking off this thread with a link to the Humble Book Bundle Unix:
Unix, I nix. We called up our friends at O'Reilly to put together this bundle of Unix resources for all! Find your nutshell reference, your pocket guide, and your power tools here. We've got you covered!
