Facebook Fiona: New Competition for Amazon Echo, Apple HomePod, and Google Home If you haven't already invested in one of the many smart home speakers on the market, this summer you'll have even more options, as Facebook plans to unveil its own version of voice-enabled smart home speakers, called Fiona and Aloha. Unlike most of the smart home speakers available today, like Amazon Echo, Google Home, and Apple HomePod, Fiona and Aloha will each feature a built-in 15-inch touchscreen. As an extra perk, Aloha will also boast facial recognition technology, which will allow users to access Facebook (and likely launch other tasks) when the smart speaker's camera lens recognizes them.   ClearStream View Wall-Frame HDTV Antenna Review: Nearly Picture Perfect By building the antenna into a large picture frame, Antenna Direct's ClearStream View is a unique solution to the visually challenging problem of how to hide an indoor antenna. ... the $70 ClearStream View is a large, black picture frame with cutouts for family photos.

You could also simply put one large, say, Monet print in the frame.   A Brief History of Aspect Ratios, a.k.a Screen Proportions This month, my Scientific American column tackles the new era of vertical video—videos shot and viewed as tall, thin rectangles, suitable for smartphone screens without having to turn them. It's kind of a mess: Vertical videos look ridiculous on TV sets and computer screens, but traditional horizontal videos play tiny and goofily on smartphones held upright. This isn't the first time aspect ratios (screen proportions) have changed—or have given society headaches. Here's a quick history lesson. (An aspect ratio is expressed as either a horizontal-by-vertical proportion, like 4:3, or as its resulting ratio, like 1.33. The smaller the ratio, the more square the picture; the larger the ratio, the wider the image.)
