• HTG Explains: Should You Shut Down, Sleep, or Hibernate Your Laptop?

Hibernate is like shutting down your computer, but you can still resume working where you left off. There’s no right answer in all situations. Some people leave their computers running 24/7, while others shut down computers the moment they step away. Each of these options has its advantages and disadvantages.

• How to Find Your Lost Android Phone, Even if You Never Set Up a Tracking App

  - by Chris Hoffman

  Android doesn’t come with a “find my Android” feature, so there’s no official way to track your phone if you lose it. You should prepare your phone for loss by setting up such a tracking app — but what if you didn’t? Your first instinct may be to download Lookout’s Plan B, which has been the go-to app for this purpose. However, Plan B only runs on Android 2.3 Gingerbread and lower, so modern Android phones will require a new solution. If you are still running 2.3 or lower, you should definitely check it out, but everybody else can keep reading.

• Unit testing to prove balanced tree

  - by Darrel Hoffman

  I've just built a self-balancing tree (red-black) in Java (language should be irrelevant for this question though), and I'm trying to come up with a good means of testing that it's properly balanced. I've tested all the basic tree operations, but I can't think of a way to test that it is indeed well and truly balanced. I've tried inserting a large dictionary of words, both pre-sorted and un-sorted. With a balanced tree, those should take roughly the same amount of time, but an unbalanced tree would take significantly longer on the already-sorted list. But I don't know how to go about testing for that in any reasonable, reproducible way. (I've tried doing millisecond tests on these, but there's no noticeable difference - probably because my source data is too small.) Is there a better way to be sure that the tree is really balanced? Say, by looking at the tree after it's created and seeing how deep it goes? (That is, without modifying the tree itself by adding a depth field to each node, which is just wasteful if you don't need it for anything other than testing.)
