Now in its third edition, Lifehacker: The Guide to Working Smarter, Faster, and Better ($19) is the perfect guide for streamlining your life — and unlike other tutorial books, you won’t feel like an idiot being seen with it. Featuring 121 new and classic hacks, tricks, and downloads from Lifehacker’s archives, the third edition has been updated to provide advice on using the latest mobile and desktop operating systems. We personally love the advice on mowing down email, and dealing with the insanity that can be managing multiple google accounts. Versions are available in dead tree, kindle, and ePub formats to suit your reading style. If you prefer the latter format, note that Lifehacker is offering a promo code to consumers who buy directly from their publisher here. Just type in code LHB3E for 40% off through June 30th.

Editor’s Note: Our reader Nate points out that the process for downloading the ePub discounted book offered by Lifehacker isn’t an easy proposition for iPad owners. He graciously sacrificed his time to figure it out and shared the details of how he did it with us, but the bottom line is don’t expect to get it on your iPad without quite a bit of work.
