By its very nature, searches on Google Images are very visual things -- but that's not to say they couldn't be enhanced with some non-pictorial content. And that's exactly what Google has done, adding captions to image search results to make them more useful.

The aim is to provide greater context about results, giving users the chance to judge the quality of the image, and to perhaps determine whether the host site will have other useful images.

Ultimate Ears Bluetooth speakers are just the tops. They are well built, sound great, and are reasonably priced. Its lowest cost offering, the WONDERBOOM, is a remarkable value at just $99. Heck, the little guy is waterproof and floats.

Christine Lagarde, the head of the International Monetary Fund (IMF), has said that the blockchain technology behind cryptocurrencies could also be used to regulate them. She suggests that the IMF "fight fire with fire" in trying to address the "dark side of the crypto world."

While acknowledging the potential for the technology behind crypto-assets as being massively empowering -- particularly as a way to provide low-cost payment methods in poorer countries -- she says that cryptocurrencies also need regulation to avoid problems such as money laundering and funding terrorism.

This year’s Mobile World Congress was one of the best I’ve attended. While there was a lot of hype around the launch of Samsung’s Galaxy S9 , which looks pretty great, overall there was less of a focus on specific models and operating systems and more attention being paid to the new technologies that are solving customers’ problems, such as artificial intelligence (AI) and the Internet of Things (IoT).

Here are my main takeaways from this year’s show:

After a long flight, the first thing we do, as soon as we hit the runway, is switch our phone out of airplane mode and check our messages, emails and make sure we can connect to the local mobile network.

The problem is, this is expensive and most users mobile contract does not offer them free roaming, especially at long-haul destinations. You want to be connected to Wi-Fi as soon as possible.

It's become quite clear that the idea of having major updates available in a timely fashion remains a distant dream for many Android users. Lots of smartphones remain a version or two behind the latest big release of the popular operating system, even though the hardware is more than capable of handling it.

Trouble is it's not (just) obscure companies that are failing users, but major players too. Take Samsung and the Galaxy S8 for instance. The Oreo roll-out only just started, but it's based on Android 8.0 -- not 8.1, as you would expect. Fortunately, there are some exceptions, most notably OnePlus and its two most-recent flagships.
