Automatic object recognition in images is currently tricky. Even if a computer has the help of smart algorithms and human assistants, it may not catch everything in a given scene. Google might change that soon, though; it just detailed a new detection systemthat can easily spot lots of objects in a scene, even if they're partly obscured. The key is aneural network that can rapidly refine the criteria it's looking for without requiring a lot of extra computing power. The result is a far deeper scanning system that can both identify more objects and make better guesses -- it can spot tons of items in a living room, including (according to Google's odd example) a flying cat. The technology is still young, but the internet giant sees its recognition breakthrough helping everything fromimage searches through to self-driving cars. Don't be surprised if it gets much easier to look for things online using only vaguest of terms.
You can now instruct Facebook to encrypt every email it sends to you so nobody — not even the NSA — is likely to be able to read your messages anytime soon. All you have to do is import your public PGP key into your Facebook settings and you’re good to go. The problem here, of course, is that most people have no idea how public/private key email encryption works and how to even get started with it. In the wake of Edward Snowden’s leaks, a number of organizations, including Google, promised to completely hide the complexities of end-to-end email encryption from regular users. Very few of these products have materialized so far, however — not for lack of trying, but because this is actually a very complex problem, both from a technical and user experience perspective. Facebook uses the well-established PGP scheme (the GNU Privacy Guard implementation of OpenPGP, to be precise) to encrypt messages and tools lik...
